In Search of Causes of Hung Juries

A major problem facing the jury system is the hung jury. Several solutions have been proposed i.e., to minimize the decision rule, to create mixed juries, or to give the jury the 'dynamite' instructions. Nevertheless, no efforts have been made to determine the underlying causes of a hung jury. This paper presents an empirical study of hung versus unanimous juries in terms of the deliberation style and content. It suggests ways of avoiding hung juries.     

“Transient structures”: The effects of practice and distractor grouping on within-dimension conjunction searches

It has been stated that whereas between-dimension (color × orientation) conjunctions can be searched in a “parallel” fashion, within-dimension (color × color) conjunctions are necessarily searched in a “serial self-terminating” fashion (Wolfe et al., 1990). We explored the effects of practice (within 1-h experimental session) and distractor grouping on within-dimension conjunction search tasks. In Experiments 1 and 3, the stimuli were rectangles formed by two adjacent squares; in Experiment 2, the stimuli were plus signs formed by two segments and an intersection. In Experiments 1 and 2, observers were assigned to one of two experimental conditions: In one, all the distractors shared a simple feature (the color blue); in the other, distractors did not share that simple feature. In the first condition, search became more efficient with practice and observers’ performance was characterized by a shallow reaction time (RT) × set size slope; in the second condition, observers’ performance did not improve as much with practice. We propose that the differential effects of practice between these two experimental conditions can be explained in terms of distractor grouping induced by the shared color of the distractors. Experiment 3 showed that, with practice, a shallow RT × set size slope characterized observers’ search for a color × color target among four different distractors that shared a common color. The present results contradict a main tenet of some current visual search models— namely, that within-dimension conjunctions cannot be searched in parallel, and question the validity of using RT × set size slope functions to distinguish between preattentive versus attentive search.     

Social behavior and off-target verbosity in elderly people

This study investigated social behavior in older adults with varying levels of off-target verbosity (OTV). After screening 455 adults in Phase 1, 198 individuals were selected to participate in both a get-acquainted conversation and an experimental cues situation and to complete social and cognitive measures. Higher OTV participants had lower cognitive inhibitory scores, talked more, were less interested in their partners, and focused more on themselves. Their conversational partners were less satisfied. Age and cognitive functioning were not related to OTV scores or conversational style for low- and mid-range participants. Although high-OTV individuals talked less when exposed to social cues signalling boredom, they spoke more relative to other participants. Self-reported social behavior had little relation with OTV and conversational style, but higher OTV individuals were less accurate in judging videotaped social interactions. Gender differences in conversational behavior are also discussed.     

Role of anxiety and brooding in specificity of autobiographical recall

Overgeneral schemas and lack of autobiographical memory (AM) specificity about our past experiences can predict mood disturbance. Rumination, functional avoidance and executive processes are the main explanatory variables of such overgenerality. However, in non‐clinical samples, rumination predicts overgenerality most consistently after the induction of dysphoric mood. Anxiety also activates rumination. Furthermore, anxiety predicts memory performance and has effects on mood which are independent of the effects of rumination. So, what might be the role of anxiety in autobiographical memory performance? A sample of 210 voluntary participants reported measures of autobiographical memory, anxiety, rumination (brooding and reflection), functional avoidance and executive functions (semantic and phonetic verbal fluency task). Autobiographical performance (specificity) was negatively associated with brooding and age and positively with phonetic verbal fluency but not with functional avoidance and anxiety. However, anxiety and brooding were positively correlated even after controlling for depression scores. Moreover, using structural equation modeling, anxiety showed a significant indirect effect on autobiographical specificity through brooding rumination. These results suggest a possible association of anxiety with autobiographical recall through brooding rumination.     

Protective behavioral strategies and the relationship between depressive symptoms and alcohol-related negative consequences among college students

Approximately 40% of college students reported engaging in heavy episodic or "binge" drinking in the 2 weeks prior to being surveyed. Research indicates that college students suffering from depression are more likely to report experiencing negative consequences related to their drinking than other students are. The reasons for this relationship have not been well-studied. Hence, the purpose of this study was to determine whether use of protective behavioral strategies (PBS), defined as cognitive-behavioral strategies an individual can use when drinking alcohol that limit both consumption and alcohol-related problems, mediated the relationship between depressive symptoms and alcohol-related negative consequences among college students. Data were obtained from 686 participants from a large, public university who were referred to an alcohol intervention as a result of violating on-campus alcohol policies. Results from structural equation modeling analyses indicated that use of PBS partially mediated the relationship between depressive symptoms and alcohol-related negative consequences. Implications for clinicians treating college students who report experiencing depressive symptoms or consuming alcohol are discussed.

The Benefits of Using Psychotherapy Skills Following Treatment for Depression: An Examination of “Afterwork” and a Test of the Skills Hypothesis in Older Adults

It has long been assumed that one of the reasons clients maintain improvement after psychotherapy is that they learn skills during the course of therapy and continue to apply them once therapy has ended. While research on homework completion and psychotherapy outcome provides support for this assumption, there has been no direct examination of “afterwork,” the use of skills learned in therapy after therapy has ended, or how those posttherapy skills differ across different theoretical approaches. The purpose of this study is to test a skills hypothesis of long-term psychotherapeutic benefit in a sample of 90 older adults who have completed psychotherapy for depression. Helpfulness of the techniques learned in therapy was negatively associated with depressive symptoms up to 2 years after treatment. The number of techniques used was positively correlated with depressive symptoms within 6 months of treatment once helpfulness was controlled, indicating that skills learned in therapy are used when symptoms return. There were also between-group differences in which skills were reported to be covered and used by patients after therapy ended. These findings support the expectation that the benefits of therapy are extended by continuing to use helpful skills learned in therapy.     

Measuring alcohol-related protective behavioral strategies among college students: further examination of the Protective Behavioral Strategies Scale.

Heavy drinking among college students has been recognized as a public health problem on American college campuses (e.g., R. Hingson, T. Heeren, M. Winter, & H. Wechsler, 2005). Recently, protective behavioral strategies, or cognitive-behavioral strategies that can be implemented when using alcohol to reduce consumption and resulting negative consequences, have been shown to be associated with less alcohol use and fewer alcohol-related problems (e.g., S. L. Benton et al., 2004; M. P. Martens et al., 2005). The purpose of the present study was to conduct additional psychometric work on a measure designed to assess the use of such strategies: the Protective Behavioral Strategies Scale (PBSS; M. P. Martens et al., 2005). Data were collected on 505 undergraduate students from 2 universities who reported having consumed alcohol at least once in the past 30 days. Results of a confirmatory factor analysis supported the hypothesized 3-factor version of the PBSS, and scores on each subscale were correlated in the expected direction with both alcohol use and alcohol-related problems. Thus, the PBSS appears to be reliable and valid for use among college student drinkers.     

Self-monitoring and the prediction of one's own and others' personality test scores

This study had two aims. Firstly, it examined the similarity between subjects' ratings of themselves and others and their scores on various personality tests. A group of 264 undergraduates in psychology completed Snyder's (1974) Self-Monitoring Scale and the Neuroticism and Extraversion Scales from the Eysenck Personality Questionnaire (Eysenck and Eysenck, 1975; 1986). Then, they estimated both their own score and that of a peer on those questionnaires. The results showed that subjects (i) were fairly good at estimating their own and others' extraversion and neuroticism scores, (ii) were less accurate at estimating self-monitoring scores, (iii) were better at predicting their own scores than those of others, and (iv) erroneously believed themselves to be significantly similar to the chosen peer. Secondly, individual differences in the accuracy of personality estimation were studied. According to Synder's (1974) self-monitoring construct, people high in self-monitoring would be especially adept at reading others' expressive behaviours; therefore, any differences in the accuracy of perceiving the personality of others might be associated with differences in self-monitoring. High self-monitors were more accurate than low self-monitors at estimating neuroticism scores for others. Another implication of the self-monitoring theory is that, taking high and low self-monitors as targets of others' estimations, there should be greater discrepancy between actual scores and peer estimations for high self-monitors. The results here supported this prediction, but only in self-monitoring estimation.     

Activation and elaboration effects in recognition and word priming

Two experiments investigated the effect of direct and indirect activation on subsequent accessibility to individual items. In the first experiment, words were semantically processed in the context of either phonologically (rhyming) or conceptually (categorical) related words and tested subsequently for recognition and word completion. On the completion test the initial three letters of a word are presented for completion. The previously presented target word is one of several possible completions. The presence of different contexts had no differential effect either on recognition memory—which persisted at high levels for two days—or on completion—which decayed in the course of about 15 min.

In the second experiment, the contexts were presented but the target words were not. Thus the rhyming and categorical contexts were directly activated but not the actual words that were scored on the subsequent tests. Prior activation of phonologically similar items affected both recognition and completion performance on immediate testing, but not after 10 min. Conceptual activation affected only recognition—an effect that lasted for a period of days. Completion performance demonstrates access to the integration component of recognition. The results were compared with attempts to demonstrate independence of recognition and completion.
