Exploring interhemispheric collaboration in older compared to younger adults

Physical and Name Identity letter-matching tasks were used to explore differences in interhemispheric collaboration in younger and older adults. To determine whether other factors might also be related to across/within-hemisphere processing or visual field asymmetries, neuropsychological tests measuring frontal/executive functioning were administered, and comparisons were made for participants split into low and high efficiency groups based on performance on the letter-matching tasks. A Task by Across/Within interaction was found for both groups, but with a stronger within-hemisphere advantage for the Physical Task and a weaker across-hemisphere advantage for the Name Task for older participants. More efficient groups and better performers on several neuropsychological tasks showed a reduced across-hemisphere advantage for the Name Identity task. Findings suggest that computational complexity, specific task demands, and perhaps trade-offs between age-related changes in gray and white matter all contribute to whether processing loads are distributed across or within hemispheres as we age.     

In search of the silver lining: the justice motive fosters perceptions of benefits in the later lives of tragedy victims

Past research has demonstrated that people's need to perceive the world as fair and just leads them to blame and derogate victims of tragedy. The research reported here shows that a positive reaction--bestowing additional meaning on the lives of individuals who have suffered--can also serve people's need to believe that the world is just. In two studies, participants whose justice motive was temporarily heightened or who strongly endorsed the belief that reward and punishment are fairly distributed in the world perceived more meaning and enjoyment in the life of someone who had experienced a tragedy than in the life of someone who had not experienced tragedy, but this pattern was not found for participants whose justice motive was not heightened or who did not strongly endorse a justice belief. These results suggest that being motivated to see the world as just--a motivation traditionally associated with victim derogation--also leads people to perceive a "silver lining" to tragic events.     

Target-uncertainty effects in attentional capture: Color-singleton set or multiple attentional control settings?

Previous spatial cuing studies have shown that the capture of spatial attention is contingent on top-down attentional control settings whose specificity varies as a function of the certainty of the defining features of the target. For example, when the target is a singleton defined by one specific color, observers adopt a control setting for that color. When the target can be one of two possible colors, however, observers appear to adopt a control setting for color singletons in general (see, e.g., Folk & Remington, 2008). The present study tested whether such results instead reflect the simultaneous maintenance of control settings for multiple colors (Adamo, Pun, Pratt, & Ferber, 2008). Observers searched for targets that were unpredictably red or green, preceded by spatial cues that were red, green, or blue. All three cue types produced evidence of capture, consistent with a general set for color singletons rather than the maintenance of multiple control settings.     

Achieving difficult agreements: Effects of Positive Expectations on negotiation processes and outcomes

Two studies demonstrate that negotiation processes and outcomes can be altered by the creation of Positive Expectations. Study 1 participants were American undergraduates seeking agreement with a confederate about allocation of funds to programs differentially favoring undergraduates vs. graduates. Study 2 participants were Israeli Business School students seeking agreement with an Arab confederate about allocation of funds to projects differentially favoring Israelis vs. Palestinians. In both studies prior information suggesting the consistent success of previous dyads prompted acceptance of the confederate’s “final proposal” whereas merely urging participants to try to reach agreement resulted in consistent rejection of the same proposal. Moreover, participants reaching agreement in these Positive Expectations conditions subsequently offered more positive assessments of the negotiation process and of their counterpart than those doing so in control conditions. The theoretical and applied relevance of these findings, including the role played by post-agreement dissonance reduction, are discussed.     

Students’ stereotypes of professors: an exploration of the double violations of ethnicity and gender

This study examined students’ stereotypes of professors based on professor ethnicity, gender, teaching style, and course taught. An ethnically diverse sample of undergraduates (N = 594) rated hypothetical professors on several dimensions including perceived warmth, professional competence, and difficulty. Evidence consistent with response amplification and expectancy violation theories was found. Women professors were viewed as more warm than men professors even though their course syllabuses were identical. Students’ ratings of women and Latina/os were, in some cases, based on their teaching style and the courses they taught, whereas ratings of Anglo men were not. Implications for women and Latina/os in the academy are discussed.     

Support for Affirmative Action Initiatives Among Diverse Groups: The Role of Ethnic Identity

This study investigates the relationships among demographic factors (race/ethnicity, color, and gender), ethnic identity (i.e., the degree to which one identifies with and feels a part of one's racial or ethnic group), and support for affirmative action initiatives. Using a sample of 1,880 university employees, the results of this survey study reveal that women and minority group members express higher levels of ethnic identity and support for affirmative action initiatives, mirroring previous research. In addition, the findings indicate that ethnic identity and support for affirmative action initiatives are correlated and that ethnic identity serves as a mediator and moderator in the relationship between demographic variables and support for affirmative action for some subgroups.     

Managing Employees in the Service Sector: A Literature Review and Conceptual Development

Our economy is slowly shifting from a manufacturing base to a service base. Yet, management literature has been slow to respond. We know little about the unique challenges faced by managers in the service sector. This paper reviews literature on research on management practice and employee perceptions that lead to positive customer outcomes. Specifically, relational coordination efforts by a manager are suggested to lead to specific employee behaviors that have been correlated with customer outcomes. This literature review and conceptual development are presented here in hopes that future research will take a deeper look at the challenges faced by service sector managers.     

Interactive effects of life experience and situational cues on aggression: The weapons priming effect in hunters and nonhunters

Recent research (Anderson, Benjamin, & Bartholow, 1998) indicates that the presence of guns increases the accessibility of aggressive thoughts via automatic priming. Our research examined whether this “weapons priming effect” differs depending on the structure of an individual's knowledge about guns, and if so, whether that difference results in corresponding differences in aggressive behavior. Experiment 1 revealed that individuals with prior gun experience (hunters) have more detailed and specific information about guns than do individuals with no direct gun experience (nonhunters), and that hunting experience interacts with gun type (hunting versus assault) in predicting affective and cognitive reactions to guns. Experiment 2 revealed that pictures of hunting guns were more likely to prime aggressive thoughts among nonhunters, whereas pictures of assault guns were more likely to prime aggressive thoughts among hunters. Experiment 3 showed differences in aggressive behavior following gun primes that correspond to differences in affective and cognitive responses to gun cues. Our findings are discussed in light of the General Aggression Model.
