Eysenck's theory of criminality and the personality types and offences of young delinquents

It has been proposed recently that the conflicting findings in studies of Eysenck's theory of criminality may be explicable in terms of the different personality subgroupings within the criminal population. It is proposed further that these different personality types may be associated with particular kinds of offences.The results of the present study confirm the existence of different personality types within a delinquent population. Four subgroups were identified, two of which were consistent with predictions from Eysenck's theory. The four subgroups could be distinguished on the basis of number of previous convictions but not by the kinds of offence committed. It is suggested, however, that future studies of this question, instead of examining kinds of offence committed, should focus their attention on situational components of the offences committed by the different personality subgroups.The general pattern of results is interpreted as supporting a modified or limited model of Eysenck's theory of criminality.     

Recognition memory for pictures as a function of poststimulus interval: an empirical clarification of existing literature

Shaffer and Shiffrin (1972) found no effect of the duration of a blank poststimulus interval on recognition memory for visual scenes. The majority of subsequent studies, however, have found a positive relationship between interval duration and recognition accuracy. The present experiments were conducted to clarify these contradictory outcomes. Experiment 1 determined that Shaffer and Shiffrin's results are replicable with the method that they used in which stimulus durations and poststimulus-interval durations vary randomly within the study list. Experiments 2-3 showed that this random intermixing of durations is the critical factor that results in poststimulus interval having no effect. The results were interpreted in terms of a voluntary rehearsal process that is abandoned when there is uncertainty regarding the time of onset and offset of the stimuli.     

The role of motion in infants' perception of solid shape

Previous research has shown that infants as young as the first few months of life perceive several aspects of the three-dimensional environment. Yet we know relatively little about the visual depth information which serves as a basis for their spatial capacities. A study is reported in which a visual habituation procedure was used to examine what types of optical depth information four-month-old infants find useful in visually perceiving solid (three-dimensional) shape. Results imply that in the absence of binocular depth cues four-month-olds rely on kinetic depth information to perceive solid shape.     

The ecological approach to perceiving as a foundation for understanding the development of knowing in infancy

The ecological thesis of direct realism is used as a framework for examining the development of knowing in human infancy. When information for perceiving is defined ecologically (i.e., relative to the situational context and to the physical dimensions, capabilities, and needs of the perceiver), knowing need not be construed as the act of using representations to give meaning to acts or percepts. Knowing, alternatively, is the act of noticing affordances, situation and perceiverspecific meanings of objects, according to their value to the perceiver for achieving specific goals. Changes with development in infant sensorimotor functioning may, in this view, be explained by a process of increasing economy in noticing potentially available affordances, rather than a process of constructing a representational system for making present something not present. Studies of three infant skills widely attributed to the onset of representation are examined with regard to this ecological thesis. Results indicate that the noticing of affordances is critically involved in each of these skills.     

Genetic foundation of social behaviour

This contribution was invited by the Editor, and translated by him from the German. Dr Schlegel is a leading exponent of the large group of German workers in the field of constitutional psychology and medicine. He lectured on these topics at the University of Hamburg before being forced to leave his post in the first half of the 1970s by militant students during the German equivalent of the Chinese “cultural revolution”. His work, which fits well into the new school of socio-biology, is relatively unknown in English-speaking countries and, in view of its originality and importance, should be more widely read. Dr Schlegel, in line with socio-biological thinking generally, has not confined himself to a narrow study of correlations between physique and personality, but has also tried to integrate his findings into a wider social context.     

A comparison of observed and reported adult-infant interactions: Effects of perceived sex

Interactions of 16 adults (eight married couples whose youngest child was less than 2 1/2 years old) with a single actor infant, dressed as either a male or a female, were recorded and analyzed in four categories: direction of gaze, facial expression, physical contact with the infant, and toy used. After the interaction period, a 45-minute interview on child rearing was conducted with each member of the couple. Observed interactions were then compared with interview data. The results support previous studies which show that both male and female parents behave differently toward unfamiliar infants on the basis of perceived sex. However, parents, especially mothers, appeared unaware of their differential treatment of male and female infants. These results suggest subtle sex-typing of infants by adults.     

Working through a group's fantasy of the deceased leader's wish for the group's continuation

This paper reflects the working through of a group's fantasy that the deceased group leader wished the group to continue. As in any defense, the fantasy protected members from the pain of the finality of the leader's death. This article reveals the subjective experience concerning the effect of the leader's death on the group and members' intrapsychic struggle to separate and individuate from the deceased leader, while attending to and striving toward the group's continuation. The group's painful and growing individuation enabled the group to follow its own tasks without the spector of the deceased leader.     

The deterrent effect of capital punishment during the 1950s

This investigation examines the deterrence hypothesis of an inverse relationship between state execution rates and homicides. Although this question has received some attention in recent studies, the findings of these investigations are mixed. Cross-sectional analyses of states have typically shown execution and homicide rates to be positively associated, while at least two national time-series studies report support for the deterrence hypothesis. To test whether these divergent findings are result of the two different methodologies employed (cross-sectional vs. time-series), a methodology that combines the strengths of each is used in the present study. For the period 1950 to 1960, we examine cross-sectionally for states the relationship between changes in execution rates and changes in murder rates. This analysis does not find support for the deterrence argument for the certainty of the death penalty when a number of models of the execution rate--murder rate relationship are considered, and when a variety of imprisonment and socio-demographic factors are considered as control variables.     

A factorial study of a new measure of authoritarianism

In the present study scores on Ray's Directiveness scale were subjected to Varimax rotation. Three factors explaining more than 50% of the variance of authoritarianism were interpreted and labelled Submissiveness, Dominance and Aggressiveness, respectively. Although these are in line with Ray's earlier conception of the nature of authoritarianism and do, to some extent, support other findings, it is suggested that the Directiveness scale be expanded to accommodate more characteristics of authoritarianism such as rigidity, hostility and superstitiousness.     

Malpractice in clinical social work: A perspective on civil liability in the 1980's

Recently reported cases involving the malpractice of psychiatrists have also focused attention on the potential liability for similar acts by clinical social workers. While there is no appellate case authority holding social work clinicians liable for malpractice at this time, the potential for such litigation is enormous. This article explores some of the more common areas of concern and suggests several prophylactic measures that clinicians may employ to safeguard both their professional career and their continued financial independence.
