Angry facial expressions hamper subsequent target identification

There is considerable evidence indicating that people are primed to monitor social signals of disapproval. Thus far, studies on selective attention have concentrated predominantly on the spatial domain, whereas the temporal consequences of identifying socially threatening information have received only scant attention. Therefore, this study focused on temporal attention costs and examined how the presentation of emotional expressions affects subsequent identification of task-relevant information. High (n = 30) and low (n = 31) socially anxious women were exposed to a dual-target rapid serial visual presentation (RSVP) paradigm. Emotional faces (neutral, happy, angry) were presented as the first target (T1) and neutral letter stimuli (p, q, d, b) as the second target (T2). Irrespective of social anxiety, the attentional blink was relatively large when angry faces were presented as T1. This apparent prioritized processing of angry faces is consistent with evolutionary models, stressing the importance of being especially attentive to potential signals of social threat.     

Social neuroeconomics: the neural circuitry of social preferences

Combining the methods of neuroscience and economics generates powerful tools for studying the brain processes behind human social interaction. We argue that hedonic interpretations of theories of social preferences provide a useful framework that generates interesting predictions and helps interpret brain activations involved in altruistic, fair and trusting behaviors. These behaviors are consistently associated with activation in reward-related brain areas, such as the striatum, and with prefrontal activity implicated in cognitive control, the processing of emotions, and integration of benefits and costs, consistent with resolution of a conflict between self-interest and other-regarding motives.     

Antecedents of Children's Adult Outcomes in the Texas Adoption Project

ABSTRACT Four composite variables concerning life outcomes were derived from a brief mail questionnaire describing 478 adults, now in their 30s and 40s, who had participated as children in the Texas Adoption Project. Responses were obtained from the participants themselves, their parents, and their siblings. MMPI scores of the parental generation were correlated with the adult outcomes of their biologically related and unrelated children. The obtained correlations were low, but for the biological relationships positive parent adjustment went with positive life outcomes of their children, whereas for adoptive relationships the reverse was the case. Favorable MMPI scores from late adolescence were favorably related to adult outcomes, as were favorable personality ratings from childhood.     

Predicate Logical Extensions of some Subintuitionistic Logics

The paper presents predicate logical extensions of some subintuitionistic logics. Subintuitionistic logics result if conditions of the accessibility relation in Kripke models for intuitionistic logic are dropped. The accessibility relation which interprets implication in models for the propositional base subintuitionistic logic considered here is neither persistent on atoms, nor reflexive, nor transitive. Strongly complete predicate logical extensions are modeled with a second accessibility relation, which is a partial order, for the interpretation of the universal quantifier.

What's in a name? Attachment-related attentional bias

Participants completed a dot probe task that presented pairs of first names: the participant's own name and a neutral name (Experiments 1-4), the name of their attachment figure and a neutral name (Experiments 1-4), or the name of a known person and a neutral name (Experiments 2-4). A significant attentional bias effect was found for the attachment name in attachment-related contexts, whether they were threatening or positive. The results of Experiments 2 and 4 showed that the attentional bias effects for the attachment name were not driven by familiarity effects and could not be interpreted in terms of salience. Attachment anxiety was associated with hypervigilance toward the attachment name in threatening and positive attachment contexts. Attachment avoidance was unrelated to any attentional bias effects.     

Attention for emotional faces under restricted awareness revisited: do emotional faces automatically attract attention?

Theoretical models of attention for affective information have assigned a special status to the cognitive processing of emotional facial expressions. One specific claim in this regard is that emotional faces automatically attract visual attention. In three experiments, the authors investigated attentional cueing by angry, happy, and neutral facial expressions that were presented under conditions of limited awareness. In these experiments, facial expressions were presented in a masked (14 ms or 34 ms, masked by a neutral face) and unmasked fashion (34 ms or 100 ms). Compared with trials containing neutral cues, delayed responding was found on trials with emotional cues in the unmasked, 100-ms condition, suggesting stronger allocation of cognitive resources to emotional faces. However, in both masked and unmasked conditions, the hypothesized cueing of visual attention to the location of emotional facial expression was not found. In contrary, attentional cueing by emotional faces was less strong compared with neutral faces in the unmasked, 100-ms condition. These data suggest that briefly presented emotional faces influence cognitive processing but do not automatically capture visual attention.     

A time-course analysis of attentional cueing by threatening scenes

Models of attention and emotion have assigned a special status to the processing of threatening information: Facilitated attentional capture by threat and its prioritized processing would allow for swift and adequate action to potentially dangerous stimuli. In four experiments, we examined the time-course of facilitated orienting of attention to threatening scenes in the exogenous cueing paradigm. Threat value and presentation duration of the cues were systematically varied. Facilitated attentional capture by threat was limited to highly threatening pictures presented for 100 ms. No attentional effects were observed with a 28 ms cue presentation duration. At slightly longer cue presentations, 200 ms and 500 ms, results indicated no and even reduced attentional capture by threat compared with neutral information. The present results provide support for the idea that threat facilitates fast attentional orienting to its location, followed by the inhibition of attention to threat.     

Current-events knowledge in adults: an investigation of age, intelligence, and nonability determinants.

This study expanded the scope of knowledge typically included in intellectual assessment to incorporate domains of current-events knowledge from the 1930s to the 1990s across the areas of art/humanities, politics/economics, popular culture, and nature/science/technology. Results indicated that age of participants was significantly and positively related to knowledge about current events. Moreover, fluid intelligence was a less effective predictor of knowledge levels than was crystallized intelligence. Personality (i.e. Openness to Experience) and self-concept were also positively related to current-events knowledge. The results are consistent with an investment theory of adult intellect, which views development as an ongoing outcome of the combined influences of intelligence-as-process, personality, and interests, leading to intelligence-as-knowledge (P. L. Ackerman, 1996b).
