Patterns of experience with verbs affect long-term cumulative structural priming

Recent studies of structural priming have demonstrated that although there is evidence of verb-based effects in short-term priming (e.g., stronger priming when verbs are repeated between prime and target sentences), such effects are absent in long-term priming. We present evidence that verb-based effects can be observed in long-term priming situations. This result has important implications for theoretical accounts of the mechanisms that give rise to structural priming and other such adaptation effects in language production.     

A longitudinal twin study of the genetic and environmental etiology of maternal hostile-reactive behavior during infancy and toddlerhood

Children's negative characteristics are thought to be a factor in evoking hostile parenting responses. This can result in genotype/environment correlations (rGE) in which children's heritable traits influence the parenting they experience. We did genetic analyses on 292 mothers' self-reported hostile-reactive behaviors toward each of their twins at 5, 18 and 30 months. Finding heritability for a parenting behavior analyzed as a child phenotype is evidence of rGE correlation. The heritability of maternal behavior was modest (29% at 5 months, 0% at 18 months, and 25% at 30 months) and longitudinal analyses indicated that genetic factors at 5 and 30 months were uncorrelated. Common environment factors, probably reflecting characteristics of the mothers, were the main source of variance at the three ages and were highly correlated through time. We concluded that children's heritable characteristics evoked maternal negative response at specific times, but were not responsible for the stability of maternal hostility from infancy to toddlerhood.     

The Effects of Images of African American Women in Hip Hop on Early Adolescents’ Attitudes Toward Physical Attractiveness and Interpersonal Relationships

This qualitative study was designed to identify African American early adolescents’ subjective meanings of African American women’s sexuality through an examination of Stephens & Phillips (2003) sexual images—the Diva, Gold Digger, Freak, Dyke, Gangster Bitch, Sister Savior, Earth Mother, and Baby Mama. These eight sexual images both inform and reflect beliefs about African American women’s physical attractiveness. Interpersonal relationship decision making processes also were influenced by these conceptual frameworks of African American women’s sexuality. Findings from this study are important given the tendency of previous researchers to ignore race and intraethnic variations in studies of beliefs about attitudes toward sexuality.     

Leadership styles and Deming's behavior factors

Although total quality management scholars, including W. Edwards Deming, consider leadership to be important, there has been little work which considers linkages between specific leadership styles and TQM behaviors/policies. This paper examines the relationship between a full range of leadership styles (Bass & Avolio, 1994) including laissez-faire, management-by-exceptionpassive, management-by-exception-active, transactional and transformational leadership, and five specific TQM behavior factors derived from Deming's (1986) Fourteen Points, i.e., change agency, teamwork, trust-building, short-term goal eradication and continuous improvement.The authors gratefully acknowledge the helpful suggestions of Boas Shamir, Don Spangler, Bruce Avolio, Francis Yammarino, and Susan Kang to earlier versions of this paper.     

Looming Threats and Animacy: Reduced Responsiveness in Youth with Disrupted Behavior Disorders

Theoretical models have implicated amygdala dysfunction in the development of Disruptive Behavior Disorders (DBDs; Conduct Disorder/Oppositional Defiant Disorder). Amygdala dysfunction impacts valence evaluation/response selection and emotion attention in youth with DBDs, particularly in those with elevated callous-unemotional (CU) traits. However, amygdala responsiveness during social cognition and the responsiveness of the acute threat circuitry (amygdala/periaqueductal gray) in youth with DBDs have been less well-examined, particularly with reference to CU traits. 31 youth with DBDs and 27 typically developing youth (IQ, age and gender-matched) completed a threat paradigm during fMRI where animate and inanimate, threatening and neutral stimuli appeared to loom towards or recede from participants. Reduced responsiveness to threat variables, including visual threats and encroaching stimuli, was observed within acute threat circuitry and temporal, lateral frontal and parietal cortices in youth with DBDs. This reduced responsiveness, at least with respect to the looming variable, was modulated by CU traits. Reduced responsiveness to animacy information was also observed within temporal, lateral frontal and parietal cortices, but not within amygdala. Reduced responsiveness to animacy information as a function of CU traits was observed in PCC, though not within the amygdala. Reduced threat responsiveness may contribute to risk taking and impulsivity in youth with DBDs, particularly those with high levels of CU traits. Future work will need to examine the degree to which this reduced response to animacy is independent of amygdala dysfunction in youth with DBDs and what role PCC might play in the dysfunctional social cognition observed in youth with high levels of CU traits.     

Multiple factors of cognitive failure and their relationships with stress vulnerability

Use of the Cognitive Failures Questionnaire (CFQ) in clinical research assumes that the questionnaire measures a single factor. A factor analysis of the CFQ was performed, on a sample of 475 students, using accurate procedures for determining the number of factors. These procedures gave mutually inconsistent results: at least two alternative factor structures can be extracted from the CFQ. An interpretable seven factor solution was found, but the CFQ probably has insufficient items to measure more than two strongly defined factors. The capacity of CFQ multiple factors to predict measures related to stress vulnerability was tested in a further study (N=57). Correlations between CFQ total score and neuroticism and use of coping strategies appeared to depend mainly on a single CFQ multiple factor, related to failures of concentration. Some of the other CFQ factors predicted other criteria. Further research on multiple factors of cognitive failure might improve the validity of the CFQ as a predictor of stress vulnerability and of cognitive performance.     

Interactive Links Between Theory of Mind,Peer Victimization,and Reactive and Proactive Aggression

This study investigated the relation between theory of mind and reactive and proactive aggression, respectively, as well as the moderating role of peer victimization in this context. The 574 participants were drawn from a longitudinal study of twins. Theory of mind was assessed before school entry, when participants were 5 years old. Reactive and proactive aggression as well as peer victimization were assessed a year later in kindergarten. Results from multilevel regression analyses revealed that low theory of mind was related to a high level of reactive aggression, but only in children who experienced average to high levels of peer victimization. In contrast, a high theory of mind was related to a high level of proactive aggression. Again, this relation was especially pronounced in children who experienced high levels of peer victimization. These findings challenge the social skills deficit view of aggression and provide support for a multidimensional perspective of aggressive behavior.
