Psychopathic Traits in Boys With and Without Attention-Deficit/Hyperactivity Disorder: Concurrent and Longitudinal Correlates

To investigate the role of psychopathic traits in a clinical and comparison sample, we obtained dimensional California Child Q-Set (CCQ) personality profiles for 66 preadolescent boys with attention-deficit/hyperactivity disorder (ADHD) and 56 comparison boys during naturalistic summer programs and correlated each boy's CCQ profile with an expert-derived CCQ psychopathy prototype. These scores, representing each boy's degree of similarity to the prototype, were significantly associated with concurrent externalizing diagnoses and symptoms and, with statistical control of these externalizing features, concurrent measures of objectively observed noncompliance, overt and covert antisocial behavior, and peer sociometric nominations indexing peer rejection. Psychopathic traits were not associated with peer acceptance. CCQ psychopathy dimension scores also predicted severity of delinquency at a 5-7-year prospective follow-up, with statistical control of age, baseline externalizing diagnoses and symptoms, and baseline objective observations of antisocial behavior. Predictions held when overt behavioral items from the CCQ, which may have overlapped with the delinquency outcome criterion, were eliminated. Despite these strong effects, a plethora of false positives were evident in the prospective predictions to delinquency status. We discuss research and clinical implications of measuring psychopathic traits in childhood.     

The effect of repetition on search through active memory

Short lists of digits, some of which contained repeated items, were searched in memory. Repeated items were recognized faster than non-repeated items. Search times for non-repeated items in lists with a repeat were slightly faster than those for lists of the same length in which no items were repeated. A serial position effect was found such that items at either the beginning or end of the memory list were responded to faster than items in the middle of the list. Neither the repeated digit effect nor the serial position effect support serial exhaustive search. An empirical equation was found by which response time is predicted by the log proportion of items in a memory list that match the test stimulus. These results are compatible with the notions of neural pathway activation and trace strength.     

Fairness and preference

Two equity models were evaluated by fitting them to subjects' judgments of the fairness of payment distributions to “self” and “other” under hypothetical work situations. Neither the E. Walster, G. W. Walster, and E. Berscheid (Equity: Theory and Research, Boston: Allyn and Bacon, 1978) equity formulation nor Harris' (Journal of Experimental Social Psychology, 1976, 12, 194–209) linear model adequately accounted for the fairness judgments regardless of whether self worked more or less than other. Subjects also were asked to indicate their most preferred payment distributions and these preferences were significantly different from the fairness judgments. Results suggested that fairness judgments were influenced by a bias in the direction of overpayment to self.     

Alcoholics treated by individualized behavior therapy: One year treatment outcome

One-year treatment outcome results are reported for 70 male alcoholics who, while hospitalized at Patton State Hospital, served as subjects in an experiment evaluating ‘Individualized Behavior Therapy (IBT)’ techniques. Initially, subjects had been assigned to a controlled drinking or non-drinking (abstinence) treatment goal, and then were randomly assigned to either an experimental group receiving IBT or a control group receiving conventional state hospital treatment. One year follow-up results demonstrated that IBT treated subjects had functioned significantly better than control subjects. Dependent variable measures included daily drinking disposition, general emotional adjustment, vocational satisfaction, occupational status, driving status and an index of residential status and stability. The results support the view that some ‘alcoholics’ can acquire and maintain controlled drinking behavior over at least a 1-yr follow-up interval. The difficulties of designing and applying sophisticated follow-up procedures and measures are discussed.     

Imitative play behavior of children: The importance of model distinctiveness and prior imitative training

The frequency of play behaviors of nursery school and second grade subjects (N = 116) who were imitative of one of two models depended upon the extent to which the two models were previously distinguished by the proportion of reinforcement each delivered, and whether reinforcement delivery was contingent upon imitative behavior. A model, high in distinctiveness and also involved in prior imitative training, engendered reliably more imitations than models high (or low) in distinctiveness but involved in nonimitative (or imitative) training.     

Effects of density,activity, and personality on environmental preferences

The effects of room density, type of ongoing activity (party vs studying), and a personality variable (“personal space” or the distance which subjects place between themselves and others) on room liking were investigated. Results supported the prediction that type of activity is an important determinant of whether a high or low density setting is preferred. Evidence was also presented that a mediator between activity type and density preference is whether the presence of other people facilitates or inhibits the individual's goals in the setting. Personality factors also influence density preferences: Close standing Ss preferred a high to a low density setting; far standing Ss showed an opposite preference pattern, but only in the party condition. Correlations between Ss' personal space scores and several background and personality variables are also presented.     

Writers and critics: Two types of vocational consciousness in the art system

Vocational interests, personality, work environment, and background of authors and critics, male and female, in children's literature are examined in terms of Holland's theory of vocational types, supplemented with concepts of an art system and styles of consciousness. On SVIB indicator scales, both authors and critics score as artistic types with “consistent” profiles, but authors are more “differentiated.” Critics have stronger social interests and less aversion to conventional activities, appropriate to their position as gate-keepers in the art system. In work style there are again common features, but authors describe themselves as having “alternative” states of consciousness, where critics emphasize their social roles and rationality. Both groups have peaks on Achievement via Independence (CPI), but the critics are more socially ascendant, efficient, and conventional. Most critics have full-time employment under institutional auspices; most writers do not. Difference in occupations of fathers of authors and critics are consistent with interest patterns of the subjects. Several personality and background findings, including interactions between sex and field, are interpreted as supporting the usefulness of supplementing Holland's theory.     

A comparison of parents' models and expansions in promoting children's acquisition of adjectives

This study investigated the effects of parental models plus nondifferential praise and expansions plus nondifferential praise on 2-year-old children's spontaneous use of color and size adjective-noun combinations. Mothers modeled either a color or size adjective-noun combination and expanded the other. Both parental models and expansions increased the children's spontaneous use of the target adjective-noun combinations, but expansions produced a stronger effect than models. These results, and naturalistic data indicating that parents often provide a large number of expansions for their children, suggest that expansions may play an important role in normal language development.     

Developmental changes in retention: Independent of age?

It is commonly believed that age differences in memory are due primarily to input processes and secondarily, if at all, to retention processes. The present study examined this belief with a test-retest paradigm, varying rehearsal conditions orthogonal to age (first- and second-graders vs. college students). Large age effects were found for both original learning and retention, and these effects were independent of rehearsal conditions. An estimate of the relative magnitude of each suggested that age effects on retention were about half as large as age effects on original learning (e.g., input).     

Natural anchoring at the neutral point of category rating scales

Contextual theories of judgment assume that the rating of any stimulus depends on its relationship to a context of similar stimuli. For example, any specific act of behavior would be rated less favorably when considered in the context of good behaviors then when considered in the context of bad ones. However, two experiments suggest an absolute anchoring of the natural neutral point, an exception to this generalization. In Experiment 1, morally indifferent acts remained “neutral,” regardless of context; and in Experiment 2 the break-even or zero-point in a simulated game of chance was always rated “neutral.” In both experiments, contextual manipulations had powerful effects upon ratings of other stimuli, though never shifting them across the neutral point. Furthermore, both experiments suggest that neutral-point anchoring also affects the use of the most extreme categories in a manner that is unique to this phenomena. In Experiment 2 for example, the introduction of extremely positive “wins” not only made other wins seem less favorable while leaving ratings of the zero-point unchanged, but also made the most negative losses seem more favorable. It is as if the introduction of an extremely positive “win” also introduces the possibility of an extremely negative “loss.” Taken together these findings contradict the basic adaptation-level premise that the entire scale is determined by the neutral point; they are also inconsistent with the assumption of range theories that the scale is anchored by the endpoints of the range of stimuli actually experienced.
