Public but not private ego threat triggers aggression in narcissists

One line of research indicates that people are more aggressive when they are insulted publicly rather than privately, whereas another indicates that subclinical narcissism predicts aggression. Drawing on these lines of research, we predicted that aggression would be increased among participants who scored higher on narcissism (as opposed to lower), received negative (as opposed to positive) self‐relevant feedback, and did so in public (as opposed to private). The findings supported that prediction and further confirmed that narcissism was only predictive of aggression in the negative‐public condition. The findings thus indicate that aggression is influenced by the interaction of situational and dispositional factors. Copyright © 2011 Crown in the right of Canada.

Late adolescent nonsuicidal self-injury: the roles of coping style, self-esteem, and personality pathology

This study examined the relationship between late adolescent nonsuicidal self-injury (NSSI) and coping style, self-esteem, and personality pathology. Participants were 302 late adolescent (18-19-year-old) college students who completed questionnaires on self-esteem, coping style, personality disorder symptoms, and NSSI. Participants who engaged in NSSI reported more personality pathology, more maladaptive coping styles, less rational coping, and lower self-esteem than did non self-harming participants. As hypothesized, total NSSI correlated with several personality disorders, emotional coping style, and inversely related to self-esteem and adaptive coping styles. Regression equations tested several mediation models to determine whether self-esteem or coping style mediates the relationship between personality disorder symptoms and NSSI. Emotional coping and self-esteem each fully mediated the relationship between various personality disorders and NSSI in the anticipated direction. Results also indicate self-esteem, rational, detached, and emotional coping partially mediate the relationship between several personality disorders and NSSI.     

Positive overgeneralization and Behavioral Approach System (BAS) sensitivity interact to predict prospective increases in hypomanic symptoms: a behavioral high-risk design

Recent work has identified Behavioral Approach System (BAS) sensitivity as a risk factor for the first onset and recurrence of mood episodes in bipolar disorder, but little work has evaluated risk factors for the prospective development of hypomanic symptoms in individuals at risk for, but without a history of, bipolar disorder. The present study used a prospective behavioral high-risk design to evaluate the impact of positive overgeneralization, a cognitive correlate of risk for hypomania, on hypomanic symptoms in individuals with high vs. moderate BAS sensitivity, but without a history of mood elevation. Hierarchical linear regressions indicated that upward positive overgeneralization and BAS sensitivity interacted to predict increased levels of hypomanic symptoms at follow-up, controlling for initial hypomanic symptoms. The pattern of this interaction was such that positive overgeneralization predicted higher levels of hypomanic symptoms among high-BAS, but not moderate-BAS, individuals. Thus, the self-reported tendency to experience grandiose increases in confidence following success may confer additional risk for mood elevation among individuals already at risk for developing bipolar disorder. Potential implications for prevention and treatment are discussed.     

Vision-fair neuropsychological assessment in normal aging, Parkinson's disease and Alzheimer's disease

We examined performance of healthy older and younger adults and individuals with Alzheimer's disease (AD) and Parkinson's disease (PD) on digit cancellation, a task putatively sensitive to cognitive impairment, but possibly affected by visual impairment, particularly in contrast sensitivity. Critical contrast thresholds were established to create custom stimulus arrays that were proximally matched across individuals. Age- and PD-related differences in search were fully accounted for by the sensory deficit. Increased contrast benefited AD patients, but could not override cognitive impairment. We conclude that visually fair neuropsychological testing can effectively compensate for normal age- and PD-related visual changes that affect cognitive performance.

Parenting Young Children (PARYC): Validation of a Self-Report Parenting Measure

The measurement of parenting behaviors is important to the field of psychology and the goal of remediating problematic parenting as a means of reducing child problem behaviors. The Parenting Young Children (PARYC) is a self-report measure designed to address parenting behaviors relevant for the caregivers of young children, and was assessed in sample of 579 high risk families. The measure assesses the frequency of several parenting behaviors, the perception of the parenting behaviors as problematic, and the degree to which the caregiver would like to make changes in specific parenting skills. An examination of the validity of the parenting behavior items revealed three parenting scales: (1) Supporting Positive Behavior (2) Setting Limits, and (3) Proactive Parenting. Confirmatory factor analysis results corroborate the findings of the exploratory factor analysis, supporting the measurement structure of these parenting scales. Tests of convergent validity indicate the PARYC scale is a suitable measure of parenting behaviors. In addition, the self-perception of parenting behaviors as problematic predicted concurrent levels of service utilization while controlling for simultaneous child behavior problems.     

Priming semantic relations in patients with Huntington's disease

To investigate the hypothesis that Huntington's Disease involves a breakdown in the organization of the lexico-semantic representational system, mildly and moderately demented patients with Huntington's Disease and age-matched normal control subjects were given a brief battery of language tests and a semantic priming free association task. Results of the language tests provided suggestive, but confounded, evidence for a semantic deficit in Huntington's Disease. Less equivocal evidence was yielded by results of the priming task, which showed a decline in the effect of association strength of primed stimulus-target word pairs on target hit rates. This finding was interpreted as a disruption in the system of spreading activation in a lexico-semantic network. This breakdown was contrasted with the more severe language deficits found in dementias which are primarily cortical in origin.     

Motor learning-dependent synaptogenesis is localized to functionally reorganized motor cortex.

The regional specificity and functional significance of learning-dependent synaptogenesis within physiologically defined regions of the adult motor cortex are described. In comparison to rats in a motor activity control group, rats trained on a skilled reaching task exhibited an areal expansion of wrist and digit movement representations within the motor cortex. No expansion of hindlimb representations was seen. This functional reorganization was restricted to the caudal forelimb area, as no differences in the topography of movement representations were observed within the rostral forelimb area. Paralleling the physiological changes, trained animals also had significantly more synapses per neuron than controls within layer V of the caudal forelimb area. No differences in the number of synapses per neuron were found in either the rostral forelimb or hindlimb areas. This is the first demonstration of the co-occurrence of functional and structural plasticity within the same cortical regions and provides strong evidence that synapse formation may play a role in supporting learning-dependent changes in cortical function.     

The Visual Guide to Morality: Vision as an Integrative Analogy for Moral Experience,Variability and Mechanism

Analogies help organize, communicate and reveal scientific phenomena. Vision may be the best analogy for understanding moral judgment. Although moral psychology has long noted similarities between seeing and judging, we systematically review the “morality is like vision” analogy through three elements: experience, variability and mechanism. Both vision and morality are experienced as automatic, durable and objective. However, despite feelings of objectivity, both vision and morality show substantial variability across biology, culture and situation. The paradox of objective experience and cultural subjectivity is best understood through constructionism, as both vision and morality involve the flexible combination of more basic ingredients. Specifically, both vision and morality involve a mechanism that demonstrates Gestalt, combination and coherence. The “morality is like vision” analogy not only provides intuitive organization and compelling communication for moral psychology but also speaks to debates in the field, such as intuition versus reason, pluralism versus universalism and modularity versus constructionism.
