Bogus Publicity Items and the Contingency Between Awareness and Media-Induced Pretrial Prejudice

Venue surveys can be criticized because they do not attempt to control for response biases, such as the tendency to report having read about any story that seems plausible. Bogus items (fabricated publicity items) are a common way to control for this bias. In two studies we examined whether controlling for this bias changes the relation between exposure to media and prejudice. Based on two actual crimes with quite different media exposure rates, communities were surveyed about their exposure to media surrounding the case and their prejudice toward the defendants. A bogus item was included on each survey. In both studies the correlations between exposure to media and prejudice were significant and remained unchanged when data from respondents who indicated having read about the bogus item were excluded. These findings suggest that, in parallel to the social desirability literature, the response tendency to report awareness of media events does not threaten the validity of venue surveys.     

Juror decision making in eyewitness identification cases

The lay-person's knowledge of the factors that influence eyewitness memory was examined by evaluating the manner in which mock jurors integrated eyewitness evidence to draw inferences about defendant culpability and the likelihood that an identification was correct. Three hundred and twenty-one undergraduates viewed a videotaped trial within which ten witness and identification factors were manipulated between trials. Manipulation checks showed that subjects demonstrated superior memory for the evidence and the manipulated variables had their intended impact on appropriate rating scales. However, only one variable, witness confidence, had reliable effects on subjects' perceptions of culpability, on the perceived likelihood that the identification was correct, and on several other relevant dependent variables. Eight variables that have been shown to affect identification accuracy in the empirical literature had trivial effects on mock jurors' inferences. It was concluded that lay-people are insensitive to the factors that influence eyewitness memory.     

Survey of high-technology-transfer mechanisms in Japan and the USA

Based on the author's recent survey in Japan and the United States, this paper describes the principal ways how industrial researchers in those countries use certain new technologies resulting from university research. Personal communication and technical collaboration turned out to be key factors in the rapid diffusion of research results. However, Japanese government agencies and professional societies are much more active in organizing and energizing the civilian technology-transfer process than are their American counterparts.     

The relation of relative hormonal levels and physical development and social-emotional behavior in young adolescents

The study examined the relation between timing of physical maturation and problems of adjustment and peer relations. The participants were 9-14-year-old boys (N=56) and girls (N=52). Assessments of physical maturation consisted of pubertal staging according to Tanner criteria and serum determinations of luteinizing hormone, follicle stimulating hormone, testosterone, estradiol, dehydroepiandrosterone, dehydroepiandrosterone sulfate, and androstenedione. There was approximately an equal number of boys and girls in each pubertal stage. The psychological measures were the Psychopathology and Emotional Tone subscales from the Offer Self-Image Questionnaire for Adolescents and interview questions to assess interactions with peers. Psychopathology and emotional tone (sad effect) scores were higher for boys with high-for-age adrenal androgens and lower for boys with high-for-age sex steroids. Behavioral manifestations of sexuality, interest in dating, was higher for boys with high-for-age adrenal androgens. Dating and spending time with friends were higher for boys with high-for-age gonadotropins. Psychopathology and emotional tone were higher for girls with high-for-age gonadotropins. The results indicate that high-for-age hormone level or early timing of puberty generally was related to adverse psychological consequences for boys and girls, with relations being stronger for boys than for girls.     

Ensuring the validity of police use of force training

This research examined the skills and abilities required of officers to effectively manage situations where the use of force may be required. The research also considered the nature of training required to facilitate the development of these skills/abilities. Seventy Western Australia Police officers participated in focus groups. Identified skills/abilities fell into seven categories: Aware, Assess, Approach, Act, Automatic, Appraise and Adapt. With regard to developing proficiency in these skills, officers emphasised the importance of relevant, applied and dynamic training, debriefing and the use of scenarios/role plays. The research highlights the need to change the scope of annual refresher training from the appropriate and effective application of force to the effective management of situations in which the use of force may be required, in their entirety. Findings also highlight the need to change the focus of training from performance and assessment to continued skill development (i.e. practice and learning).
