Smoking mediates the effect of conscientiousness on mortality: The Veterans Affairs Normative Aging Study

This study examined the relationship between conscientiousness and mortality over 18 years and whether smoking behavior mediated this relationship. We utilized data from the Veterans Affairs Normative Aging Study on 1349 men who completed the Goldberg (1992) adjectival markers of the Big Five. Over the 18-year follow-up, 547 (41%) participants died. Through proportional hazards modeling in a structural equation modeling framework, we found that higher levels of conscientiousness significantly predicted longer life, and that this effect was mediated by current smoking status at baseline. Methodologically, we also demonstrate the effectiveness of using a structural equation modeling framework to evaluate mediation when using a censored outcome such as mortality.     

Neurobiological correlates of cognitions in fear and anxiety: a cognitive-neurobiological information-processing model

We review likely neurobiological substrates of cognitions related to fear and anxiety. Cognitive processes are linked to abnormal early activity reflecting hypervigilance in subcortical networks involving the amygdala, hippocampus, and insular cortex, and later recruitment of cortical regulatory resources, including activation of the anterior cingulate cortex and prefrontal cortex to implement avoidant response strategies. Based on this evidence, we present a cognitive-neurobiological information-processing model of fear and anxiety, linking distinct brain structures to specific stages of information processing of perceived threat.     

Wishing for Change in Japan and Canada

Japanese and Canadian university students were compared on the changes they wanted in their lives. Contrary to their characterization as self-effacingly relational and group-minded, Japanese were no more likely than Canadians to wish for social or collective goods. Rather, Japanese were more likely than Canadians to wish for money or material goods, and less likely than Canadians to wish for better family relations, increased self-understanding, and improved academic performance. Whether these findings reflect dissimilar cultural priorities, unequal opportunities and constraints, or both, is discussed.     

Peer assessments of normative and individual teacher–student support predict social acceptance and engagement among low-achieving children

This study used hierarchical linear modeling to predict first grade students' peer acceptance, classroom engagement, and sense of school belonging from measures of normative classroom teacher–student support and individual teacher–student support. Participants were 509 (54.4% male) ethnically diverse, first grade children attending one of three Texas School districts (1 urban, 2 small city) who scored below their school district median on a measure of literacy administered at the beginning of first grade. Peer nominations from 5147 classmates were used to assess both normative and individual levels of teacher support. Normative classroom teacher–student support predicted children's peer acceptance and classroom engagement, above the effects of child gender, ethnic minority status, and individual teacher–student support. Results are discussed in terms of implications for teacher preparation and professional development.     

Treatment of co-occurring child maltreatment and substance abuse

Despite high prevalence and severe negative consequences of child maltreatment (e.g., Brown, G. R., & Anderson, B., (1991). Psychiatric morbidity in adult inpatients with childhood histories of sexual and physical abuse. American Journal of Psychiatry, 148, 55–61; Jaudes, P. K., Ekwo, E., & Van Voorhis, J.V., (1995). Association of drug abuse and child abuse. Child Abuse and Neglect, 19, 1065–1075; Murphy, J. M., Jellinek, M., Quinn, D., Smith, G., & Goshkom, M., (1991). Substance abuse and serious child mistreatment: Prevalence, risk, and outcome in a court sample. Child Abuse and Neglect, 15, 197—211), the treatment of perpetrators and victims of child abuse and neglect remains grossly understudied (Behl, L. E., Conyngham, H. A., & May, P. F., (2003). Trends in child maltreatment literature. Child Abuse and Neglect, 27, 215–229). More than half of parentes founded for the abuse and neglect of their children have evidenced drug abuse, yet no treatments have been validated that concurrently address these problems. The reciprocal interaction between substance abuse and child maltreatment supports the need to concurrently treat these problems. This article illustrates the relationship between child maltreatment and parental substance abuse and proposes a behavioral model to explain the reciprocal influence of drug abuse and child maltreatment. A behavioral treatment plan that is designed to concurrently address drug abuse and child abuse is proposed and suggestions are made for future directions in this area.     

Affiliative Need,Different Types of Social Support,and Physical Symptoms1

Less tangible types of social support (emotional, informational, and companionship) were shown to predict reports of physical symptoms as a joint function of both affiliative need and negative life events, while the effects of tangible support depended only upon the occurrence of negative life events (the prototypical buffering effect). Low affiliative need individuals tended to benefit from both types of support, while high affiliative need individuals benefited primarily from more tangible support. The results were discussed in terms of the proposal that low affiliative need individuals hold a more problem-focused view of social support, while high affiliative need individuals tend to take a less personally instrumental stance toward interpersonal interaction.     

EFFECTS OF ETHNICITY,ACCENT, AND JOB STATUS ON SELECTION DECISIONS

The present study investigated the effects of ethnicity, accent, and job status in the selection interview. Two hundred and ten student subjects viewed simulated, videotaped selection interviews in which applicant ethnicity, applicant accent, and job status were manipulated in a completely crossed 3 × 2 × 2 factorial design. Two sets of ratings were obtained, selection decision ratings of the job applicant, and subjective importance ratings based on the previous selection decisions. Significant main effects were obtained for ethnicity and job status in selection decision as predicted. Contrary to predictions however, the main effect for accent was not found significant. Further analysis of the importance ratings indicated a significant main effect for accent, but not for ethnicity. These findings indicated that applicant ethnicity and job status were important in selection interview decision and accent was not. Contrary to this however, subjects considered that accent was important in their selection decision ratings, while ethnicity was not.     

The influence of context on lexical decision times for emotionally aversive words

Forty-eight undergraduates made lexical decisions about emotionally aversive and nonemotional words. Emotionally aversive target words were preceded either by an emotionally aversive prime word, a nonemotional but semantically related prime or a nonemotional and semantically unrelated prime. Nonemotional targets were preceded by nonemotional primes which were either semantically related to targets, unrelated, or neutral (strings of Xs). Primes were presented for 50 ms to one group of 16 participants, 500 ms to a second group and 1250 ms to a third group. Measurement of lexical decision time showed significant semantic primary effects for nonemotional targets, and these were not influenced by prime duration. Priming effects for emotionally aversive targets due both to emotional and nonemotional relatedness of primes and targets were also found and these effects were not influenced by prime duration. The results are considered to be consistent with Bower’s (1981) associative network theory of memory, and possible clinical implications for explaining spontaneous panic attacks and the incubation of anxiety are discussed.     

Memory for two types of spatial location: effects of instructions, age, and format

Three experiments, with old persons (59-80 years) and college students (17-30 years) in Experiments 1 and 2 and with college students (17-24 years) in Experiment 3, investigated the differences between two types of spatial location memory: memory for the location of individual items in an array and memory for occupied, as opposed to unoccupied, locations in an array. Young persons performed better than old persons on both measures of location memory. However, an effect of instructions (intentional vs. incidental for spatial location) was consistently obtained for memory for occupied, as opposed to unoccupied, locations, whereas no effect of instructions was obtained for memory for individual item locations. In addition, item location memory was superior for objects as opposed to matched words (Experiment 2), whereas occupied location memory was not affected by presentation format (Experiments 2 and 3). These differences indicate that spatial memory is a complex process whose properties are affected by variations in stimulus characteristics and task demands. It was concluded that the distinction of Hasher and Zacks (1979) between automatic and effortful processes is not adequate for understanding spatial memory. A recognition of the complex nature of spatial processing suggests a resolution of discrepancies in the literature based upon differences in stimulus characteristics, task demands, and the effectiveness of task-appropriate mnemonic strategies.
