Will jurors correct for evidence interdependence in their verdicts? It depends

Throughout an investigation, pieces of evidence are likely to contaminate one another, yet at trial jurors are expected to treat pieces of evidence as if they are independent. Are jurors able to understand potential evidence contamination? The present study showed mock jurors a videotaped trial simulation. Participants were randomly assigned to hear testimony regarding one piece of evidence, two pieces of independent evidence, or two pieces of interdependent evidence. The study tested the hypothesis that jurors who hear evidence that is interdependent will be just as likely to find the defendant guilty as jurors who hear about two pieces of independent evidence. When an eyewitness's identification was the uncontaminated piece of evidence, our hypothesis was supported. However, when the confession was the uncontaminated piece of evidence, jurors seemed to understand that one piece of evidence had been influenced by another and adjusted their beliefs about the defendant's guilt accordingly. This study supports the conclusion that jurors can sometimes identify and correct for evidence contamination in their perceptions of a defendant's guilt. Implications for reform support are discussed.     

Response competition and target word detection during shadowing in a dichotic listening task

College students (N = 24) served as subjects in a within-subjects study of auditory attention in which four tasks were performed. In the easiest task, a single passage was presented and shadowed while target word detections were indicated by pressing a key. The other three tasks also required target word detection, but a second passage was presented simultaneously. One task had no target words in the unshadowed passage; the other two tasks required a key-pressing response to the target words in both passages, either with one hand or with each hand. We expected performance to decrease as task complexity increased; this was partially confirmed. The task of shadowing and detecting target words is too difficult to be used to test perception or response limitations of attention.     

The Crosstown Initiative: Art,Community, and Placemaking in Memphis

This case study examines an arts organization at the center of an urban neighborhood revitalization effort and its contributions to creative placemaking and inclusive community building. The study documents innovative arts practices and explores their meaning for a local context, an understudied city in the Mid‐South region of the United States. It builds on the research team’s ongoing work as teachers, students, and scholars in partnership with the arts organization. It includes systematic participant observation, interviews with stakeholders, and a review of historical and contemporary media coverage. We found that the organization and its practices provided a rich context for exploring an expanded sense of community including bridging social capital and place‐based frameworks. Analysis suggests that the organization’s intentional arts based practices bring multiple understandings of community and art into meaningful dialogue through the generation of creative and social friction. These practices illustrate one context‐specific strategy addressing the tensions in a community–diversity dialectic (Townley et al. in Am J Commun Psychol 47:69–85, 2011 ).     

Physical self-concept and self-esteem mediate cross-sectional relations of physical activity and sport participation with depression symptoms among adolescent girls.

The authors tested whether physical self-concept and self-esteem would mediate cross-sectional relations of physical activity and sport participation with depression symptoms among 1,250 girls in 12th grade. There was a strong positive relation between global physical self-concept and self-esteem and a moderate inverse relation between self-esteem and depression symptoms. Physical activity and sport participation each had an indirect, positive relation with global physical self-concept that was independent of objective measures of cardiorespiratory fitness and body fatness. These correlational findings provide initial evidence suggesting that physical activity and sport participation might reduce depression risk among adolescent girls by unique, positive influences on physical self-concept that operate independently of fitness, body mass index, and perceptions of sports competence, body fat, and appearance.     

Child Support Enforcement and Father Involvement Among Victims of Intimate Partner Violence

The focus of this article will be intimate partner violence among custodial parents receiving welfare benefits and their required cooperation with the child support enforcement system to encourage the financial involvement of the noncustodial parent. The majority of the mothers in the study encouraged the father's continued emotional involvement with their child despite the violence. This article will illustrate through the use of a case study the desire of these mothers to encourage both a financial and emotional relationship with their child's father, with safety always a priority.     

Sanctity of the Body and the Relational Paradigm

The individual is in constant interaction with others from birth onwards. The primary experience evolves from the innate need for bodily touch and connection, which form the foundation for the psychobiological structure of the individual. The body’s anatomy is made to yearn for another, for building a home with the body of another. This makes the body the focal instrument, which is discernible already in the mother–child relationship, as well as later in male–female or husband–wife relationships. The body thus provides the most sacred space, and deep within it carries a natural yearning for another, for having a relationship with another. Relationships are the means through which the body can come to full realization.     

The Effects of Competition on the Decision Quality of Diverse and Nondiverse Groups

Research has validated that intragroup cooperation, rather than competition, produces more positive group interaction and interpersonal acceptance which leads to better performance. The unique values of culturally diverse group members, however, may influence group processes and performance if these group members respond differently to situational cues. Research on the interaction between cultural diversity and competitive team situations would benefit organizations that employ an increasingly diverse work force. The primary purpose of this study is to explore the effects of cultural diversity on group performance and group processes by comparing culturally diverse and culturally nondiverse groups under conditions of intergroup competition and noncompetition. This experiment was conducted using 500 upper-level undergraduate students enrolled in a principles of management course at a large university in the southwestern United States. The results of this experiment indicate that the competitive nondiverse groups performed better than did the noncompetitive diverse groups in terms of quality of performance. Results also suggest that both the culturally diverse and culturally nondiverse groups outperformed their best individual members' scores when they were matched with competitive situations that enhanced their innate group processing styles. Organizations can increase their effectiveness by appreciating that diverse and nondiverse groups respond differently under conditions of competition and noncompetition.     

Addendum to "Summation in the chimpanzee (Pan troglodytes)"

Rumbaugh, Savage-Rumbaugh, and Hegel (1987) reported that two chimpanzees (Pan troglodytes) could select, with better than 90% accuracy, the greater of two paired quantities of chocolate chips. In that study, no one quantity of chocolates (from 0 through 5) was used in both pairs on a given trial. We investigated the effect of having one quantity in common (CQ) in both pairs. Whether the other quantities (OQs) of chocolates were both less than or greater than the CQ, summation still occurred. Accuracy was primarily a function of the ratios of sums to be differentiated. This finding substantiated the earlier conclusion that summation was based on both quantities of each pair and not on some simpler process such as the avoidance of the tray with the smallest single amount or selection of the tray with the single largest amount.
