Comparing the Predictive Accuracy of Case Linkage Methods in Serious Sexual Assaults

The empirical support for linkage analysis is steadily increasing, but the question remains as to what method of linking is the most effective. We compared a more theory‐based, dimensional behavioural approach with a rather pragmatic, multivariate behavioural approach with regard to their accuracy in linking serial sexual assaults in a UK sample of serial sexual assaults (n = 90) and one‐off sexual assaults (n = 129). Their respective linkage accuracy was assessed by (1) using seven dimensions derived by non‐parametric Mokken scale analysis (MSA) as predictors in discriminant function analysis (DFA) and (2) 46 crime scene characteristics simultaneously in a naive Bayesian classifier (NBC). The dimensional scales predicted 28.9% of the series correctly, whereas the NBC correctly identified 34.5% of the series. However, a subsequent inclusion of non‐serial offences in the target group decreased the amount of correct links in the dimensional approach (MSA–DFA: 8.9%; NBC: 32.2%). Receiver operating characteristic analysis was used as a more objective comparison of the two methods under both conditions, confirming that each achieved good accuracies (AUCs = .74–.89), but the NBC performed significantly better than the dimensional approach. The consequences for the practical implementation in behavioural case linkage are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

Acquisition of expertise on a difficult perceptual-motor task by an amnesic patient

While numerous studies have reported learning of perceptual-motor skills by amnesic patients, few if any have documented the eventual acquisition of expertise on a given task. This paper recounts the learning of the computer game Tetris by a hippocampal amnesic, whose acquisition of the task in a formal evaluation was somewhat slower than that of a comparison group, but who after many hours of self-paced practice achieved expert-level play.     

Bullying and victimization in elementary schools: a comparison of bullies, victims, bully/victims, and uninvolved preadolescents

Research on bullying and victimization largely rests on univariate analyses and on reports from a single informant. Researchers may thus know too little about the simultaneous effects of various independent and dependent variables, and their research may be biased by shared method variance. The database for this Dutch study was large (N = 1,065) and rich enough to allow multivariate analysis and multi-source information. In addition, the effect of familial vulnerability for internalizing and externalizing disorders was studied. Gender, aggressiveness, isolation, and dislikability were most strongly related to bullying and victimization. Among the many findings that deviated from or enhanced the univariate knowledge base were that not only victims and bully/victims but bullies as well were disliked and that parenting was unrelated to bullying and victimization once other factors were controlled.     

The assessment of cognitive procedural learning in amnesia: why the tower of Hanoi has fallen down

The Tower of Hanoi has been widely accepted as an evaluation of cognitive procedural learning in amnesia but inconsistent findings have raised questions about the nature of the learning process involved in this task. This article presents the performance of a hippocampal amnesic, MS, who, showing poor learning across daily sessions of a formal evaluation, subsequently solved the puzzle through spontaneous use of a declarative-level strategy (the odd-even rule), suggesting that his primary approach to the task was the deployment of declarative solution-searching strategies. The presented data suggest normal learning within daily sessions, but subnormal learning across daily sessions due to the forgetting of acquired declarative information. It is suggested that tasks that are potentially solvable by an algorithm or rule, as is the Tower of Hanoi, be regarded as inappropriate for use in cognitive procedural assessments.     

Using Motive Scores in the Psychobiographical Study of an Individual: The Case of Richard Nixon

ABSTRACT Content analysis measures of imagery for the achievement, affiliation-intimacy, and power motives were applied to Richard Nixon's 1969 first inaugural address The resulting motive profile–high achievement, high affiliation-intimacy, and average in power motivation–was validated through a systematic analysis of the course of Nixon's everyday behavior as reported in the memoirs of six aides, and was also used to explain several paradoxes of Nixon's political career     

Responsibility and the power motive in women and men

Previous research on the correlates of power motivation in women and men had shown no gender differences, when the presence of younger siblings (reflecting responsibility training) was used as a moderator variable This study reports development of an empirically derived direct TAT measure of responsibility as a moderator variable for the power motive The new measure includes mention of legal or moral standards, obligation concern about others, concern about consequences, and self-judgment It is related to perceived parental expectations concerning responsibility Among women and men high in responsibility, power motivation predicts responsible social power actions, but among women and men low in responsibility, power motivation predicts a variety of profligate, impulsive actions Responsibility then, rather than gender, appears to determine the ways in which the power motive is expressed     

How automatic are social judgments?

Do people infer personality dispositions automatically when they encode behavior? Tulving's encoding-specificity paradigm was adapted to test three operational indicants of automatism: absence of intention, of interference from other mental activity, and of awareness. Recruited for a digit-recall study, subjects read sentences describing actions during the retention interval of either an easy or a difficult digit recall task. Later, sentence recall was cued by (a) disposition cues, (b) strong semantic associates to the sentence actor, or (c) words representing the gist of the sentence, or (d) sentence recall was not cued. Awareness was measured immediately after the last sentence was read. Disposition-cued recall was higher than (b) or (d) and was unaffected by digit recall difficulty. Awareness of making dispositional inferences was only weakly correlated with disposition-cued recall. Results suggest that disposition inferences occurred at encoding, without intention, without interference by differential drain on processing capacity, and with little awareness. Thus, making dispositional inferences seems to be largely, but not entirely, automatic.     

Socialization and themes in popular drama: An analysis of the content of child-rearing manuals and Don Juan plays in sixteenth to twentieth centuries

A content analysis is reported of child-rearing manuals published in sixteenth to nineteenth centuries and of the themes of the Don Juan plays in seventeenth to twentieth centuries. The relationship between the content of the manuals and the themes of the plays supports the thesis that child-rearing patterns advocated in one century are reflected in the next in the attitudes expressed in popular cultural activities towards aggression, achievement and sex roles.
