Automatic and voluntary control of attention in young and older adults

Young and older adults searched for a target character in a 3-item display. On each trial, both a symbolic cue (arrow at fixation) and a spatial cue (abrupt onset of one item) could indicate the target's position. Participants were told to use the central arrow cue on all trials because it had 75% validity. The onset cue also had 75% validity for half the participants and 25% validity for the other half. Both age groups showed about the same cost and benefit effects for the central arrow cues, but the abrupt onsets had much larger cuing effects for older adults. Young adults were able to suppress at least partially an automatic attentional response to an abrupt onset item when the arrow cue preceded the onset and had a higher validity than the onset cue. Older adults appeared to be less able to inhibit their responses to abrupt onsets and to disengage their attention from invalid onset cues than were the young adults.     

Peer victimization and social anxiety in adolescence: a prospective study

This study reports a one‐year prospective investigation of the relations between overt and relational victimization and social anxiety and phobia in a sample of adolescents. The Social Experience Questionnaire—Self Report Form (SEQ‐S), Social Anxiety Scale for Adolescents (SAS‐A), and Social Phobia and Anxiety Inventory for Children (SPAI‐C) were administered to 144 ninth grade adolescents. A follow‐up assessment with the SEQ‐S, SAS‐A, and SPAI‐C was conducted one year later. Results indicated that relational victimization predicted symptoms of social phobia but not general social anxiety and avoidance one year later. Overt victimization was not a significant predictor of social anxiety and phobia one year later. Social anxiety and phobia did not predict peer victimization one year later. However, increases in social anxiety and social phobia symptoms (for boys) over time were positively associated with increases in relational victimization over time. Implications of these findings for peer victimization and social anxiety in the development of social phobia and negative peer experiences are discussed. Aggr.

Happiness Inducing Behaviors in Everyday Life: An Empirical Assessment of “The How of Happiness”

The frequency of Happiness Inducing Behaviors (HIB) was assessed in a survey of 903 university students; measures of Big Five personality traits and happiness were also obtained. Students reported engaging in many HIBs about 1–3 times per week. Analysis of HIB yielded three factors: Positive/Proactive Behaviors; Spiritual Behaviors; and Physical Health Behaviors. Positive/Proactive behaviors predicted significant additional variance in happiness beyond the variance predictable from Big Five personality traits. Mediation analysis suggested that effects of Big Five traits on happiness may be mediated to varying degrees by engagement in Positive/Proactive Behaviors and Physical Health Behaviors. Additional analyses examined possible moderation of the association between HIB and happiness by gender and Big Five traits; the strength of association between behavior and happiness did not differ between women and men, or across people with different scores on Big Five traits. This study provides additional evidence that naturally occurring behaviors are predictive of happiness in everyday life and confirms earlier findings about the degree to which behaviors mediate effects of Big Five traits on happiness.     

Morphologic asymmetries of the face: A review

It has been suggested that asymmetries in the morphological properties of the face contribute to or produce asymmetries in facial emotional expression. Over 50 years of research on hard tissue, soft tissue, and facial surface asymmetries is reviewed here. Generally, it appears that if consistent asymmetry characterizes facial morphology, it is extremely small in magnitude or characterizes regions yet to be examined. In contrast, marked homology and asymmetry in regional size and area has been noted often. At present, it does not appear that asymmetry in facial morphology is associated with facial expressive asymmetry, with the latter more likely to be an outcome of functional brain asymmetry.
