Neighborhood Deprivation during Early Childhood and Conduct Problems in Middle Childhood: Mediation by Aggressive Response Generation

The tremendous negative impact of conduct problems to the individual and society has provided the impetus for identifying risk factors, particularly in early childhood. Exposure to neighborhood deprivation in early childhood is a robust predictor of conduct problems in middle childhood. Efforts to identify and test mediating mechanisms by which neighborhood deprivation confers increased risk for behavioral problems have predominantly focused on peer relationships and community-level social processes. Less attention has been dedicated to potential cognitive mediators of this relationship, such as aggressive response generation, which refers to the tendency to generate aggressive solutions to ambiguous social stimuli with negative outcomes. In this study, we examined aggressive response generation, a salient component of social information processing, as a mediating process linking neighborhood deprivation to later conduct problems at age 10.5. Participants (N = 731; 50.5 % male) were drawn from a multisite randomized prevention trial that includes an ethnically diverse and low-income sample of male and female children and their primary caregivers followed prospectively from toddlerhood to middle childhood. Results indicated that aggressive response generation partially mediated the relationship between neighborhood deprivation and parent- and teacher-report of conduct problems, but not youth-report. Results suggest that the detrimental effects of neighborhood deprivation on youth adjustment may occur by altering the manner in which children process social information.     

Mental exercising through simple socializing: social interaction promotes general cognitive functioning

Social interaction is a central feature of people's life and engages a variety of cognitive resources. Thus, social interaction should facilitate general cognitive functioning. Previous studies suggest such a link, but they used special populations (e.g., elderly with cognitive impairment), measured social interaction indirectly (e.g., via marital status), and only assessed effects of extended interaction in correlational designs. Here the relation between mental functioning and direct indicators of social interaction was examined in a younger and healthier population. Study 1 using survey methodology found a positive relationship between social interaction, assessed via amount of actual social contact, and cognitive functioning in people from three age groups including younger adults. Study 2 using an experimental design found that a small amount of social interaction (10 min) can facilitate cognitive performance. The findings are discussed in the context of the benefits social relationships have for so many aspects of people's lives.     

Assessing male batterers with the Personality Assessment Inventory

In this study, we sought to provide empirical data on the utility of the Personality Assessment Inventory (PAI; Morey, 1991) for the assessment of male batterers. The sample consisted of 93 men who were court mandated to treatment. In the study, we were able to replicate 2 of 3 clusters (borderline/dysphoric and nonelevated) commonly found in the literature on male batterers; however, we only partially replicated the 3rd cluster (antisocial/narcissistic). This new finding may reflect a difference in the assessment instrument used to assess male batterers (i.e., PAI). In this study, we also investigated a previously understudied subgroup of batterers, specifically, men who engage in positive impression management. In this study, we conclude that the PAI is a potentially useful instrument in assessing male batterers and provide suggestions for future research.     

Growth points in research on memory and hippocampus.

We present an overview of two of our on-going projects relating processes in the hippocampus to memory. We are trying to understand why retrograde amnesia occurs after damage to the hippocampus. Our experiments establish the generality of several new retrograde amnesia phenomena that are at odds with the consensus view of the role of the hippocampus in memory. We show in many memory tasks that complete damage to the hippocampus produces retrograde amnesia that is equivalent for recent and remote memories. Retrograde amnesia affects a much wider range of memory tasks than anterograde amnesia. Normal hippocampal processes can interfere with retention of a long-term memory stored outside the hippocampus. We conclude that the hippocampus competes with nonhippocampal systems during memory encoding and retrieval. Finally, we outline a project to understand and manipulate adult hippocampal neurogenesis in order to repair damaged hippocampal circuitry to recover lost cognitive functions.     

Hypocrites or maligned cooperative participants? Experimenter induced normative conflict in zero-sum situations

The failure to recognize the influence of two distinct forms of moral norms can lead to the misattribution of moral behavior to egoistic motives. This is illustrated in the research of Batson and his colleagues (e.g., Batson, Kobrynowicz, Dinnerstein, Kampf, & Wilson, 1997). They reported the appearance of moral failure and hypocrisy motivation in several experiments employing essentially the same “zero-sum” experimental situation. They cited as evidence the discrepancy between participants’ apparently self-serving private acts and their subsequent public ratings of the morality of what they had done as well as their recognition of the “most” moral way to behave. The research reported here supported an alternative explanation that located the experimenter’s implicit and explicit instructions as the source of the discrepancy between the participants’ private acts and their public ratings. The findings confirmed the hypothesis that Batson and his colleagues had not merely made moral norms “salient”. They had actually presented their participants with contradictory “demands”: explicitly inviting them to meet the norm of justified self-interest in private but then give public lip-service to the experimenter’s instructions as to a supererogatory way to behave. When either of the demands was removed, the “hypocrisy” no longer occurred.
