I THE FIELDDaniel Glaser





Penology is the branch of criminology concerned with government policies and practices in dealing with persons convicted of crimes. Its etymology, from the Latin poena, meaning “pain” or “suffering,” reflects the early conception of punishment as the primary objective of state action toward criminals. However, in modern times interest in punishment has been largely replaced by concern with changing the abilities, interests, attitudes, and emotions of criminals. Accordingly, as we move farther into the second half of the twentieth century, we often find the term “corrections” being used instead of “penology.”

The treatment of criminals has always been motivated by (1) the feelings of hostility and desires for revenge that criminals arouse in their victims and in those who sympathize with the victims; (2) abstract philosophies, ideologies, and religious beliefs regarding punishment; (3) prevailing theories of crime causation. Usually all three of these motives and rationales operate simultaneously, but the sequence in which they are enumerated above corresponds to the historical shift that has occurred in the relative power of each to determine penal objectives. These objectives are epitomized by four words: revenge, restraint, reformation, and reintegration. All four have always been pursued to some extent, but there have been marked changes in the frequency with which each has been explicitly set forth as the primary penal goal.

Revenge and restraint

Evidence that government concern with punishing persons who commit crimes developed primarily to replace private vengeance-seeking by the victims and their kin is provided not only by historical accounts of early judicial agencies but also by objective statistical scaling of societies on the basis of their culture traits. Freeman and Winch (1957), in an analysis of 48 societies, found that where governments do not assume this private punishment function, the society rarely is able to maintain full-time priests; without full-time priests, they do not have full-time teachers; unless they have full-time teachers, they lack full-time bureaucrats; and so on up the scale of societal complexity. Thus, it seems well established that penal activity is a prerequisite to much elaboration of other functions by government and religious institutions; when there is no penal program, the regulation of society by church or state is continually subject to restriction by the anarchy of private feuding among offenders and victims.

Until the eighteenth century in Europe, and much later in many other areas, the structuring of penal policy by the prevailing religious and political status hierarchies was explicit. The nobility was subject to a criminal law different in its specification of penalties from that which prescribed punishments for commoners. The latter were dealt with most harshly, especially when the victims of their offenses were of the nobility. This was justified by an explanation of crime as the consequence of a base nature, a condition presumed to be most frequent in the “low-born.” An alternative theory, that crimes result from the possession of one’s spirit by the devil, through witchcraft and wizardry, justified both the imposition of some punishment by clerical courts and a strong church influence on the penal policies of secular courts.

Two major influences on punishment that may be latent at all times were blatantly manifest in Europe until the end of the eighteenth century. These influences were the social distance between the punisher and the punished and the economic interests of the punisher. When the punisher could perceive the offender as both alien and inferior, there was little reluctance to impose death, torture, physical mutilation, severe corporal punishment, or some combination of these. When punisher and punished were peers, the most frequent penalties were forfeiture of property, forced labor, and banishment. Rusche and Kirschheimer (1939) exhaustively document an argument that the supply of labor also determined penal policy with respect to lower-class offenders: when labor was scarce, punishment was most often forced work in galleys or in houses of correction, but when there was a surplus of labor, punishment by death or by transportation to the colonies prevailed. [SeePunishment.]

Beccaria and modern penology

There developed in the Enlightenment, partly in reaction to the severity of punishments imposed by the nobility, a conception of all men as equal. This was equality, not in possessions or status, but in rights and in potential amenability to guidance by reason. In 1764 these conceptions were brilliantly used by Cesare Beccaria as postulates for a new penal policy. His Essay on Crimes and Punishments had an immediate and tremendous influence throughout Europe and America and is often considered the beginning of modern penology. In the half century that followed, Beccaria’s arguments were extended by Voltaire, Bentham, Romilly, and others, reflecting the philosophy of utilitarianism. This resulted in so-called “classical” criminal law, which still provides the framework for our penal codes. This legal perspective calls for punishments based on the offense, rather than on the offender, and calculated to inflict no more pain than suffices to offset the satisfaction that a crime might yield to its perpetrator.

Imprisonment and forced labor, because their ostensible severity can be precisely graduated in terms of time, were well suited to the employment by judges of what Bentham called a “felicific calculus.” This is the prescription of punishment in precise degrees of severity, so that the pain the court imposes balances the presumed gratifications from the crime. The high valuation of liberty and the respect for all humans which were fostered in the democratic revolutions also promoted a preference for imprisonment or labor as penalties, rather than torture or death. Furthermore, the public felt protected when felons were confined. As a result of these several factors, during the half century which followed publication of Beccaria’s work, imprisonment replaced capital and corporal punishment in western Europe for over two hundred felonies.

Reformation and the reformatory movement

“Classical” legal philosophy stressed dual objectives : “individual deterrence” was to offset the happiness that an offender supposedly gains from his crime, and “general deterrence” was to make nonoffenders perceive crime as not conducive to happiness. However, a different justification for imprisonment was promulgated around the time of the American Revolution in the Pennsylvania colony, many of whose Quaker leaders had been imprisoned in Britain for their religious beliefs.

Like some European Roman Catholic penal pioneers in the same period, the Quakers were inspired by the monastery cells in which monks sought spiritual reformation through isolation and meditation. Prevailing penal construction congregated groups of inmates in large rooms, but the Pennsylvanians advocated a separate cell for each offender, cutting him off from communication with his fellows. They claimed that this promoted more penitent thought, especially when these “penitentiaries” limited the reading matter in each cell to a Bible and religious tracts, with little or no work and with visits only from preachers and pious laymen.

The “Pennsylvania system” spread rapidly. It became the predominant prison pattern in continental Europe during the nineteenth and twentieth centuries. However, it was opposed as costly, and its claims of reformation were challenged by advocates of a system developed at a prison in Auburn, New York, during the first half of the nineteenth century. The Auburn system, which soon prevailed in the United States, emphasized solitary confinement at night, but congregate work during the day, under a rigid rule of silence. Later in the nineteenth century the striped suit and lock step also were identified with the Auburn system; these features largely disappeared only after World War n. Despite their ostensible contrast, both the Pennsylvania and the Auburn prison systems were based on a conception of crime as learned in communication among criminals, rather than as a purely individual calculation of alternative utilities. Both prison systems also claimed that they trained offenders in legitimate modes of thought and behavior, instead of merely deterring them.

Emphasis on training increased in the latter part of the nineteenth century with the “reformatory movement,” which is usually traced to the Elmira Reformatory in New York. This special institution for young felons developed distinctive features in the 1870s under the leadership of Zebulon R. Brockway. It borrowed from Alexander Maconochie’s Norfolk prison colony in Australia the “mark system” of awarding inmates numerical credits for each period of good behavior, with loss of these “marks” for misconduct. A specified total number of marks was required for each small reduction of restrictions or increment of comfort in the institution, as well as for release. Elmira added to this an emphasis on education and vocational training. Most major prison systems established reformatories during the subsequent half century. However, they generally replaced the mark system by less mechanically assigned hierarchies of rank and small privilege for inmates, known as “honor” systems in the United States, and elsewhere as “graded” or “step” systems.

Classification and individual treatment

Concomitant with the reformatory movement were the separate developments of probation and parole[seePenology, article onProbation and Parole]. The simultaneous emphasis on institutional programs for reform and on conditional modes of release to test how well reform was achieved reflected the development of the biological and social sciences during the nineteenth and twentieth centuries [seeCriminology]. These fostered a conception of crime not as something to be morally condemned but as a phenomenon having natural causes and, hence, controllable if these causes are identified and altered. However, a great diversity of causes seemed to be involved. Early criminological researchers, notably Cesare Lombroso, ascribed crime to biological inheritance; psychologists first emphasized imbecility, and later the emotional disturbances of early childhood, as causes of crime; sociologists called attention to deviant subcultures and to the influence of social support in delinquent and criminal activity. The most prevalent explanation for crime, therefore, became “multiple causation” [seeCrime, article onCauses of Crime]. This justified the major prison management emphasis in the second quarter of the twentieth century, “classification” and “individual treatment” of inmates.

The classification process in correctional institutions begins with medical and psychological examination of the newly received prisoner, plus a caseworker’s preparation of the inmate’s life history. These reports are discussed by the institution’s classification committee, which usually consists of the head of its custodial staff, plus the director of its school, its physician, chaplains, and caseworkers. They first assess risk of escape, of violence, or of other misconduct by the inmate. Then, within the limits posed by these custodial concerns, they recommend a program of training and treatment by which the institution may help to correct the inmate’s deficiencies. As an incentive to his compliance with this treatment program, the inmate is advised that such a self-improvement effort will enhance his prospects for parole.

Two major problems have been widely recognized in these reformation efforts. The first is the fact that society has seldom been willing to invest in its treatment programs funds sufficient to correct serious educational, vocational training, psychological, and other deficiencies of most offenders. The second is the demonstration by research that, for many offenders, such treatment does not prevent a return to crime, especially when their social acceptance and their conception of themselves as successful has been and continues to be much more immediate and frequent in criminal than in noncriminal pursuits. Accordingly, the second half of the twentieth century has seen the penal objectives of deterrence and treatment, inherited from prior periods, augmented by concern with changing the social relationships of offenders.

Social reintegration

The distinctive feature of prison management in the second half of the twentieth century has been the extent to which the social boundaries within the institutions have become permeable while the isolation of these institutions from the outside world has been reduced. This appears to have been stimulated, in part, by a series of sociological analyses of prisons as communities, as well as by increasingly rigorous research on the consequences of alternative correctional programs.

Traditionally, prisons have had castelike relationships between staff and inmates. This is especially pronounced in prisons where custody and control are the primary managerial concerns. Devices to maintain the authority of staff include quasi-military movement of inmates in mass formations and the maintenance of social distance between staff and inmates by requiring that communication between the two be only formal. Clemmer’s pioneer sociological study of the prison as a community (1940) described the tendency of inmates to become “prisonized” by learning a new language and acquiring a way of life appropriate to the regulation of their lives by staff. Sykes (1958), and the various authors who contributed to Cressey’s collection of sociological essays on the prison (1961), described the special roles inmates develop to cope with each other, as well as to corrupt the authority of staff. Most prevalent, especially in highly repressive prisons, is the “right guy” role, which emphasizes loyalty to other inmates in opposing staff efforts to learn about illicit activities in the institution, and hostility to the inmate “stool pigeon” or “rat,” who purveys such information to staff. Most influential, however, are those inmates who attain the “politician’’ role by acquiring some measure of trust from both inmates and staff. This permits them to gain from the staff and to dispense to inmates some extra “privileges,” comforts, and “inside” information and, reciprocally, to enforce inmate cooperation and order in the performance of essential prison maintenance and production work. Crosscutting these categories, especially in womens’ prisons, according to Ward and Kassebaum (1965) and Giallombardo (1966), are social types based on role differentials in homosexual relationships.

In the treatment-oriented penology of the 1930s, psychotherapy was recommended for most offenders, but the psychiatric and clinical psychological staff available in correctional institutions never sufficed to provide therapy for more than a minute proportion of the inmates. After World War n, group therapy was seen as a solution to this need, not only because one clinician could deal with several subjects simultaneously in group sessions but also because a change in the social relationships among inmates was now seen as essential to their reformation. Increasingly, emphasis then shifted to changing the “social climate” of the institutions by co-opting both nonclinical staff and inmate leaders into the therapeutic process [compare Mentaldisorders, treatment of, articlethetherapeuticcommunity].

In the post-World War n years, concern for minimizing social distance between staff and inmates developed, and gained increasing concessions from the custodially oriented components of correctional management. Techniques for social distance reduction described by Glaser (1964) included assignment of line correctional staff to lead inmate groups meeting regularly for counseling; replacement of traditional institution classification committees by classification “teams” of lower-level staff; appointment of inmates to advisory committees on institution operations; and changing from disciplinary practices of solitary confinement for definite periods to periods of confinement with intensive staff counseling, the confinement terminating only when there is some gain in staff-inmate consensus. Street, Vinter, and Perrow (see Street et al. 1966), comparing inmate leadership attitudes in youth correction institutions of diverse social climates, found inmate support for staff objectives highest when social distance was minimized. Nevertheless, controlled experiments involving random assignment of inmates to heavily counseled and to noncounseled penal units failed to demonstrate marked or consistent recidivism reduction by these programs; they appeared to promote adjustment to institutional life more than preparation for the postrelease world.

Reduction of inmate isolation

Penal practice in the 1960s is distinguished by a rapid proliferation of programs to reduce the isolation of prison populations from the outside world. This was achieved, first, by inviting outsiders into the institutions, both on a voluntary and on a paid basis, as part-time instructors, as participants in inmate discussion or hobby clubs, and simply as personal visitors to inmates out of contact with outsiders. Mutual aid organizations, such as Alcoholics Anonymous, have been especially active in these functions, and they establish social relationships with inmates which continue in the free community. Also, several prison systems markedly reduced their restriction and censoring of inmate correspondence with outside parties. Conjugal visits, allowing a married prisoner to have sexual relations with his spouse, have long been permitted in Latin America, Scandinavia, eastern Europe, and some countries of Asia, but only in the state of Mississippi within the United States.

The second mode of reducing the isolation of prisoners has been to permit their temporary release before final departure from the institution. These releases include furloughs for a few days or a week when their parole or discharge dates are near, to permit them to make home and job arrangements for the future, and simply to make their adjustments to complete release less drastic. More dramatic has been the rapid spread in America and Europe of so-called “work release,” whereby inmates of a prison are permitted to depart daily, to hold jobs in adjacent communities.

Work release, as a means for achieving the social reintegration of offenders into the community, has been limited by the fact that prisons usually are in locations remote from the major metropolitan areas from which most of their inmates come and to which they return. Therefore, new types of penal institutions developed in the 1960s, small residences in large cities to which inmates are transferred for the last few months of their prison terms. The inmates in these graduated release centers depart daily to seek employment or to work on jobs in the community, and as their release date approaches, they may leave the centers in their leisure hours more often, for recreation and to visit their prospective postrelease homes. Indeed, they often may move out of the center in their last few weeks, although they return several times per week to discuss their outside experiences.

The counseling of inmates which occurs in conjunction with these releases is much more relevant to their real problems of community adjustment than counseling generally can be under traditional forms of imprisonment. Under the new programs, discussion deals with immediate circumstances as they are encountered, while counseling during longterm confinement necessarily deals primarily with selective recollections of the past, problems of institutional life, and speculations regarding a hypothetical future. Furthermore, staff assessment of the risk involved in recommending a prisoner’s complete and permanent release is presumably much more competent when the considerations on which the assessments are based include impressions gained following the prisoner’s temporary release, rather than being restricted to observations in prison.

Concern with the integration of offenders into legitimate roles in the free community has promoted more reluctance to remove them from the cornunity in the first place. Accordingly, there has been greater use of fines and of weekend or evening confinement only, presumably as deterrent sentences for prisoners with stable employment and family relationships, both of which might be jeopardized by confinement. Indeed, the increased flexibility of release from penal confinement has meant that traditional differences between imprisonment and alternative correctional practices have diminished. It is noteworthy that in the 1960s there is a general decline in the number of people in prison in most countries for which statistics are available, despite an increase in total population and in prosecutions for major crimes. A major factor in this diminution has been the increase in the principal alternative to penal confinement—release on probation or parole.

Probation and parole are procedures for release of convicted criminals or adjudicated delinquents on a conditional basis in order to assist them in pursuing a noncriminal life, with the proviso that they may be committed or returned to a correctional institution if their behavior after release fails to meet standards of the releasing authority. If granted by a court as an alternative to incarceration, this release is generally called “probation.” If granted by an administrative agency to someone who already has served part of a term of confinement, this release is usually called “parole” in the United States and “license” in Britain. The cognate or other equivalent of the term “conditional liberation” is used in non-English-speaking countries. However, in much popular speech and even in some legal statutes within the United States “probation” and “parole” are used interchangeably.

Both probation and parole represent a shift from the classic penal goal of deterrence to the modern goal of encouraging the offender to find some legitimate alternative to crime, while continuing to restrain him for the protection of society. Probation and parole also involve postponing a final decision in dealing with the criminal; the offender’s ultimate treatment is left uncertain until he is observed further.

History of probation

Probation evolved from the common-law procedure of suspended sentence, by which a judge first imposes a specific penalty, then orders that the penalty not be enforced if the offender behaves as directed. Probation differs from suspended sentence in that the court appoints someone to assist the convicted person in achieving a law-abiding life, as well as to check whether the conditions of release are obeyed.

The first probation officer is often said to have been John Augustus, a Boston cobbler, who in 1841 volunteered to assist offenders if the court would release them to his care. By his death in 1859 he and his friends were credited with providing this service for over 2,000 persons with remarkably few failures. These voluntary services first became official government functions in Massachusetts, where an 1869 law required the Board of Charities “visiting agent” to arrange family placement for children charged with offenses and where an 1878 law authorized court employment of a probation officer to serve any offender considered reformable without punishment.

In Britain and elsewhere it is claimed that some use of voluntary supervisors in suspended-sentence cases occurred well before the work of John Augustus. However, the first British law on conditional suspension of sentence was enacted in 1879, and the modern form of British probation, providing state assistance and supervision, was not established by law until 1907.

Laws for the conditional suspension of sentences were enacted in Norway in 1887, Belgium in 1888, and France in 1891. While this concept spread rapidly, government employment of probation officers was less readily accepted. The latter practice is said to have first occurred on the Continent at Neuchatel, Switzerland, in 1891, but it did not prevail in most of western Europe until after World War i, and it spread even more slowly in eastern Europe.

Probation was introduced into most of the British colonies in Asia and Africa early in the twentieth century and was then adopted in some of the adjacent countries. Its entrance into Latin America came with the establishment of juvenile courts there in the 1920s and 1930s; but it was not accepted in most Latin American courts for adults until much later.

Probation in juvenile courts. Almost everywhere, the most extensive use of probation has occurred in juvenile courts. Here children are also placed on “unofficial probation,” by continuing their hearings for perhaps six months or a year, then dismissing their cases if they and their parents have cooperated with the probation officer and behaved as the court directed during this period. In this way the child never is officially adjudicated delinquent. Unofficial probation is the most frequent disposition of cases in many juvenile courts, while in others it is either unknown or infrequent. This confounds efforts to compare delinquency rates from one jurisdiction to the next. An analogous practice in some adult courts is known as “deferred prosecution.”

These procedures for avoiding official decrees have been criticized because the court may thereby impose stringent behavior restrictions on an accused person without fully investigating the validity of complaints against him. Fear that noncooperation would result in commitment to a correctional institution inspires compliance with unofficial probation suggestions as though they were formal court orders. However, such practices have been defended as imposing less stigma on the accused than would result from full legal proceedings and as no more likely to be abused than formal procedure.

History of parole

The term “parole” can be traced to parole d’honneur (word of honor), a type of oath known in medieval days whereby military prisoners or offenders of noble birth were released on their promise not to escape or not to resume conflict. However, the practice to which the term generally is restricted today evolved from programs to motivate desired behavior in prisoners.

In 1840, Alexander Maconochie, head of a British penal colony in Australia, instituted a system whereby convicts earned “marks” for industry and obedience and lost them through misconduct. A specified number of marks had to be accumulated before a man could enter each of four “stages” of decreased restriction in confinement. In the last stage the offenders received a “ticket of leave,” which granted them freedom for the balance of their sentence provided they had no further conflict with the law.

Sir Walter Crofton, in 1846, introduced a ticketof-leave system in Ireland under which the released prisoners had to report regularly to the nearest police station. This system was extended to England by the Penal Law of 1857, where it was called “conditional release on licence.” The term “parole” was applied to the Irish system by its proponents in the United States, who finally had it instituted in 1877 at the state reformatory in Elmira, New York. It had been adopted in 22 states by 1900 and in 44 by 1922. In almost all parole systems in the United States, government-employed parole officers supervise the releasees.

In Britain, assistance for released prisoners, whether on “licence” or fully discharged, is known as “after-care” and is performed primarily by prisoners’ aid societies. These originally were purely voluntary organizations, but they have received government financial assistance since 1862. The British local organizations federated in 1936 as the National Association of Discharged Prisoners’ Aid Societies. Officers of this organization, by law, are also officers of the Central After-Care Association, a government agency created by the Criminal Justice Act of 1948 and gradually enlarged until, after 1961, it handled most compulsory after-care cases. Rather than engage a large staff, this association frequently appoints local probation officers as its “associates” to supervise licensees in their area. Several plans for decentralization of British aftercare have been widely debated.

Preprobation and parole investigations

Probation officers generally are employees of the courts. Their work differs from that of parole officers in that, in addition to supervising released offenders, they serve as advisers to judges. They do so through their presentence investigations (called “prehearing investigations” in juvenile courts). In these inquiries the probation officer usually interviews the accused and his family and any other persons or agencies having relevant information, such as employers or the armed forces. Psychological and psychiatric examinations may also be arranged. The report on such investigations summarizes the life history of the subject, analyzes his personality and his offense, describes his current situation, and assesses his probable future behavior under alternative possible court dispositions.

Investigationspro and con. In some jurisdictions a presentence or prehearing investigation is required by law for every case; elsewhere it is often required by court policy. In dealings with convicted adults presentence reports are useful to a judge even in cases for which probation is not under consideration, for they may guide decision as to the most appropriate type of prison sentence.

There has been some objection to mandatory prehearing investigations in juvenile courts on the grounds that inquiry by a court employee publicizes the status of the accused in a way that impairs his acceptance in his neighborhood and at his workplace or school. Such damage is of particular concern in cases where the court concludes that the subject has been unjustly accused. Mandatory investigations also are alleged to damage some juveniles by delaying court action for days or weeks even when information adequate for a sound disposition of the case should be provided by persons available at the initial hearings.

There has been continual controversy regarding the right of legal counsel to examine the presentence or prehearing report, to question the probation officer on it, and to present witnesses or evidence in opposition to the findings of this report. In support of such rights, it is charged that the probation officer frequently presents hearsay evidence as fact and obtains testimony from prejudiced sources without systematically determining what others might say in rebuttal. Denial of these rights is defended on the ground that exposure of sources would limit the range of relevant character information submitted to the court and that properly trained probation officers are competent to make a thorough and impartial investigation. A compromise on this issue frequently prevails, with the judge making the factual conclusions of the probation officer’s report available to counsel, and hearing testimony in rebuttal of these conclusions, without revealing the officer’s sources of information.

Purpose of investigations. Parole officers investigate an inmate’s proposed after-prison home and employment to ascertain whether they are actually available or may involve situations conducive to crime. Usually this inquiry is undertaken only after the inmate’s parole is approved; the parole board stipulates that parole will be deferred if postrelease arrangements are not satisfactory. Officers may also endeavor to arrange housing and employment for a prospective parolee.

Men from prison, however, are so often deficient in work skills and experience, and there is such prejudice against hiring them, that many promises of postrelease employment actually are only favors granted the prisoner’s family in order to hasten his release. Such jobs usually prove only temporary or nonexistent. Consequently, many parole authorities advocate less insistence on prelease job arrangements and more assistance to newly released prisoners while they seek their own jobs.

Factors in release decisions

Probation frequently is prohibited by law to persons found guilty of so-called heinous crimes, such as murder, rape, or narcotics offenses. Advocates of rehabilitation as the primary objective in dealing with criminals object to such statutory restrictions on the grounds that they hamper the state’s adjustment of its actions to meet individual differences among offenders.

Both concern with rehabilitation and interest in protecting the public require that probation and parole decisions be based on prediction of the offender’s future conduct. This prediction includes not just assessment of the risk of further crime if the offender is released immediately but also judgment whether these prospects will be better or worse after a period of confinement. Since the potentialities of humans and the situations they may encounter can never be completely known in advance, considerable error is inevitable in all judicial and correctional prediction. Furthermore, the practice of making each decision on a purely individual basis and the lack of systematic analysis of the accuracy of past predictions impair the ability of judges or parole boards to learn from experience.

Prediction research and release procedure. Since its inception in the 1920s, probation and parole prediction research has repeatedly been heralded as a basis for scientific release decisions. Such figures as Ernest W. Burgess and Sheldon and Eleanor Glueck in the United States, Franz Exner and his students in Germany, Leslie T. Wilkins in Britain, and many others developed statistical tables relating prerelease information on offenders to their postrelease behavior. There have been numerous demonstrations that these tables generally lead to more accurate predictions than is achieved through prognosis from case impressions by correctional officials, psychiatrists, psychologists, or sociologists. Nevertheless, for about thirty years the Illinois parole system was the only agency systematically making statistical prediction data available to makers of release decisions. Resistance to this practice reflected exaggerated claims for the tables by some of their proponents, which aroused an opposition fearing that use of the tables would dehumanize casework or would make relative violation risk the sole factor in release decisions. This situation changed in the early 1960s when Britain and several jurisdictions in the United States, notably California and Wisconsin, sponsored research leading to improved tables. They treated the tables as an adjunct to other data facilitating release decisions, rather than as the sole basis for decision [see Prediction].

Supervision of probationers and parolees

The conditions under which probation or parole is granted generally are expressed as a set of rules. These usually specify a county or other area in which the releasee must remain, unless granted special permission to go elsewhere. They require regular employment or school attendance, if possible, and avoidance of known criminals. There are rules against carrying weapons and other more or less specific injunctions. Usually the probationer or parolee is required to report to his supervision officer at regular intervals and to cooperate with the officer in other ways.

Restitution and compensation. Frequently in probation, but rarely in parole, the offender is required to make restitution to the victim of his offense. Occasionally the judge may require some other compensatory action, such as unpaid labor at public agencies. Such acts have been interpreted psychologically as essential to rehabilitation, for good works give the offender a conception of himself as a good person and facilitate his identification with anticriminal persons. However, for optimum rehabilitation from such experience the offender must be inspired to undertake these acts on his own initiative, rather than just perform them involuntarily.

Role dilemma of the probation officer. Probation and parole officers often experience a conflict in their work between the requirements of assistance to a releasee and the requirements of rule enforcement. There is increasing emphasis on such positive aid as counseling, obtaining employment, and mediating family conflicts for the releasee. Such assistance may require a relationship of mutual respect and trust, while effective rule enforcement requires surveillance, inquiry, and other expressions of distrust. Solutions for this role dilemma vary from leaving surveillance exclusively to the police to counseling primarily by threat, but most practice is intermediate between these extremes.

Rehabilitation and the public interest. The granting of probation or parole implies that the state has no interest in punishing the offender but is concerned only with assuring his achievement of a legitimate way of life. Most jurisdictions, however, prescribe a minimum term of confinement before parole may begin, and some judges frequently require that a jail term precede probation. Argument for this practice asserts that prior experience of the punishment to be imposed if release conditions are violated deters the releasee from violation. An opposing argument is that confinement, particularly in the idleness characteristic of jails, is a criminalizing experience. It is also contended that a major advantage of probation for many cases is noninterruption of the subject’s employment and family relationships. Of course, the latter arguments are not relevant for the large proportion of offenders who are unemployed at the time of their trial, nor for the many who lack satisfactory family relationships.

Revocation of parole or probation generally occurs if the releasee is convicted of a felony, or if he commits serious or repeated rule violations. Usually a court hearing is required to revoke probation, and a parole board hearing to declare a parolee a violator. However, these hearings seldom can be arranged before some weeks after the releasee has been in custody.

Convergence of penal practices

In concluding the article on the field of penology, I noted that under certain new types of prison management, which are rapidly spreading, many prisons are allowing inmates who are soon due to be paroled to leave the institution during the day for private employment and to return to prison at night, as well as to depart for several days at a time on leaves or furloughs. Thus, the contrast between conditions of imprisonment and those of parole are diminishing, so that the adjustments required in making a transition from one to the other are encountered less abruptly.

A contrasting but convergent development consists in the establishment of counseling centers or residential hostels to which offenders placed on probation or parole must report when not at work or at school. The residential hostel, or “halfway house,” has most often been operated by private charitable groups, usually church-affiliated, but sometimes they are also established by government agencies. Halfway houses provide temporary shelter and counseling services for parolees or probationers for whom a satisfactory family home is not available. Those operated by private groups often also aid discharged prisoners.

A series of highly publicized experiments in special counseling programs at such shelters during the 1950s and 1960s set patterns that subsequently were widely copied. Highfields, an estate given to the state of New Jersey by the flier Charles Lindbergh, was made a residence to which delinquents could be sent for up to four months, as a condition of probation. There they participated in “guided group interaction” for several hours daily, a type of discussion oriented toward their helping each other reach an understanding of why they behaved in a delinquent manner and of how they might change this behavior. H. Ashley Weeks, Lloyd W. McCorkle, and numerous other social scientists have published analyses of this innovation (see bibliography for the article on the field of penology). Other centers followed. Some—notably those at Provo, Utah, and Essexfields, New Jersey—served only as counseling establishments, rather than as residences, so that probationers assigned to them returned daily to their homes. Under this arrangement the daily conduct of the participants in community life could become the subject of the group’s discussion. The discussion at these centers often includes the topic of whether a particular participant’s behavior warrants either revocation of his probation or alteration of its conditions, and the group’s advice frequently is followed by authorities.

Paralleling these developments have been numerous experiments with intensive parole services in California. Random assignment of parolees to smaller than usual parole caseloads—even as few as 30 cases per officer—was found associated with little or no reduction in parole-violation rates. However, a more dramatic series of experiments involved establishment of nonresidential “community treatment centers” for daily counseling and tutoring of randomly selected delinquents paroled within a month after their commitment to institutions. These parolees were assigned to caseloads of only eight to twelve per officer, with different styles of supervision specified according to a classification of the offenders on a number of psychological and sociological variables. Thus, those called “enculturated” and “manipulative” received “firm but fair” supervision, while those called “immature” received highly “supportive” counseling. For most types of offenders, these programs have been dramatically more successful, as well as less costly, than those of institutionalization, and they have spread rapidly. An additional feature of many community counseling centers, especially those for adults, has been the employment of clearly rehabilitated ex-offenders as counselors. These persons have shown unusual communication skills and influence as role models for offenders whose status they once shared.

The major thrusts in penal development have been the expansion of all services in the community and the recommendation of distinctive correctional strategies for particular types of offender. In penology, as in medicine at a much earlier period, the use of controlled experiments and the objective analysis of experience is leading to more specific prescriptions for remedial action. The function of the state in coping with delinquents and criminals has become less a matter of physical containment and more a matter of continuous corrective effort within the settings where these offenders must achieve a legitimate way of life if they are no longer to be a problem for the state.

penology The study of the management and punishment of criminals. The term is associated with the nineteenth-century movement in penal reform, which redefined prisons as correctional rather than retributive establishments, and at that time described a large number of interested parties (including reformers and lawyers) and a discrete debate. However, in its contemporary usage it normally refers to specific sociological or criminological studies of punishment and deterrence, rather than a separate intellectual or academic discourse.
