Working memory load moderates late attentional bias in social anxiety

The vigilance–avoidance hypothesis suggests that socially anxious individuals attempt to detect signs that they are being evaluated (vigilance) and subsequently direct attention away from such stimuli (avoidance). Although extensive evidence supports vigilance, data concerning subsequent avoidance is equivocal. Drawing from models of attention, the current study hypothesised that working memory load moderates late attentional bias in social anxiety such that avoidance occurs if working memory load is low, and difficulty disengaging attention occurs if working memory load is high. Forty-one undergraduates (19 socially anxious; 22 non-anxious controls) completed a dot-probe task with emotional (happy and disgust) and neutral facial expressions and a concurrent n-back task. Results supported the hypothesis such that socially anxious subjects demonstrated avoidance of disgust faces when working memory load was absent, but had difficulty disengaging attention during high working memory load. Theoretical implications and directions for future research are discussed.     

Within-person variations in self-focused attention and negative affect in depression and anxiety: A diary study

This study examined within-person co-occurrence of self-focus, negative affect, and stress in a community sample of adolescents with or without emotional disorders. As part of a larger study, 278 adolescents were interviewed about emotional disorders. Later, they completed diary measures over three days, six times a day, reporting their current thoughts, affect, and levels of stress. Negative affect was independently related to both concurrent stress and self-focus. Importantly, the association between negative affect and self-focus was stronger among participants with a recent unipolar mood disorder, compared to those with an anxiety disorder, comorbid anxiety and depression, or those without an emotional disorder. The implications of these findings to theories of self-focus and its role in emotional disorders are discussed.     

Survival processing of faces

The mnemonic benefit of rating words according to their relevance in a survival scenario is well documented (e.g., Nairne, Thompson, & Pandeirada, 2007). The present study examined whether the survival processing effect would extend to face stimuli. We tested this hypothesis in five experiments, using multiple survival and control scenarios, real and computer-generated face sets, within- and between-subjects designs, and several memory tests, as well as free recall of survival-relevant and survival-neutral attribute statements written about the person. Although the standard survival processing effect was obtained for survival-relevant and neutral attribute statements, the survival processing effect was not obtained for face memory across all experiments. These results identify an important boundary condition for survival processing benefits.     

Levels of Community Engagement in Youth Violence Prevention: The Role of Power in Sustaining Successful University-Community Partnerships

Previous research indicates that communities can be engaged at various levels in research to reduce youth violence. In this paper, we argue that the method of power sharing among partners is a central factor distinguishing different levels of engagement. Using cases from the Nashville Urban Partnership Academic Center of Excellence, we identify community initiation and community collaboration as distinct approaches to community engaged violence prevention research. The power relationships among partners are analyzed to highlight differences in the types of engagement and to discuss implications for establishing and sustaining community partnerships. Also, the implications of levels of engagement for promoting the use of evidence-based practices are discussed.     

Sun,Wind, Rock and Metal: Attitudes toward Renewable and Non-renewable Energy Sources in the Context of Climate Change and Current Energy Debates

Current energy debates are often framed in terms of the extent to which energy sources may mitigate global climate change (GCC) and facilitate energy independence (EI). However, little is understood about whether and how attitudes towards GCC and EI influence attitudes toward energy sources. Our study included 277 undergraduate students enrolled in introductory psychology classes at a large, Southeastern university. As hypothesized, results from ordinal and binary logistic regression analyses revealed that the likelihood participants would support the use of solar, wind, coal or nuclear energy decreased as a function of their belief that an energy source contributed to GCC. The belief that an energy source contributed to EI increased participants’ likelihood of support. Results suggest that beliefs about GCC and EI are important to determining support for energy sources and will likely contribute to effective marketing strategies and efforts to implement more environmentally-sustainable behavior and energy policy.     

The signature of inhibition in theory of mind: children’s predictions of behavior based on avoidance desire

Theory-of-mind reasoning may require inhibitory processing, a view for which we provide new, more direct, evidence. Our research capitalizes on the lingering property of inhibition: After a response is inhibited, it temporarily becomes more difficult to select than uninhibited responses. In two experiments, 3-year-olds predicted to which of three buckets a girl would go, given a desire to avoid one (e.g., the red one). When next predicting where a boy would play, children were biased against the location the girl had avoided. However, predictions for the boy were unbiased when not preceded by predictions for the girl. These findings suggest that preschoolers predict behavior based on avoidance desires by inhibiting the target to be avoided, as well as that the inhibition lingers, reducing the target's accessibility for subsequent predictions.     

Modeling the Impact of Control on the Attractiveness of Risk in a Prospect Theory Framework

Many decisions involve a degree of personal control over event outcomes, which is exerted through one's knowledge or skill. In three experiments we investigated differences in decision making between prospects based on a) the outcome of random events and b) the outcome of events characterized by control. In Experiment 1, participants estimated certainty equivalents (CEs) for bets based on either random events or the correctness of their answers to U.S. state population questions across the probability spectrum. In Experiment 2, participants estimated CEs for bets based on random events, answers to U.S. state population questions, or answers to questions about 2007 NCAA football game results. Experiment 3 extended the same procedure as Experiment 1 using a within-subjects design. We modeled data from all experiments in a prospect theory framework to establish psychological mechanisms underlying decision behavior. Participants weighted the probabilities associated with bets characterized by control so as to reflect greater risk attractiveness relative to bets based on random events, as evidenced by more elevated weighting functions under conditions of control. This research elucidates possible cognitive mechanisms behind increased risk taking for decisions characterized by control, and implications for various literatures are discussed.     

The causes and consequences of transient epileptic amnesia

Transient epileptic amnesia (TEA) is a recently recognised syndrome of epilepsy in which the principle manifestation of seizures is recurrent episodes of isolated memory loss. In this article, we describe the clinical and cognitive profile of this emerging syndrome, and present new data that provide at most weak support for its proposed relationship to cerebrovascular disease. TEA is often associated with two unusual forms of interictal memory impairment: accelerated long-term forgetting and remote memory impairment. We discuss the clinical and theoretical implications of these relatively novel cognitive deficits.     

Powerful postures versus powerful roles: which is the proximate correlate of thought and behavior?

Three experiments explored whether hierarchical role and body posture have independent or interactive effects on the main outcomes associated with power: action in behavior and abstraction in thought. Although past research has found that being in a powerful role and adopting an expansive body posture can each enhance a sense of power, two experiments showed that when individuals were placed in high- or low-power roles while adopting an expansive or constricted posture, only posture affected the implicit activation of power, the taking of action, and abstraction. However, even though role had a smaller effect on the downstream consequences of power, it had a stronger effect than posture on self-reported sense of power. A final experiment found that posture also had a larger effect on action than recalling an experience of high or low power. We discuss body postures as one of the most proximate correlates of the manifestations of power.     

Finding levels of abstraction in speech production: evidence from sound-production impairment

A widely held view in linguistics and psycholinguistics is that there are distinct levels of processing for context-independent and context-specific representations of sound structure. Recently, this view has been disputed, in part because of the absence of clear evidence that there are abstract mental representations of discrete sound-structure units. Here, we present novel evidence that separate context-independent and context-specific representations of sound structure are supported by distinct brain mechanisms that can be selectively impaired in individuals with acquired brain deficits. Acoustic data from /s/-deletion errors of 2 aphasic speakers suggest both a phonological level of processing at which sound representations (e.g., /p/) do not specify context-specific detail (e.g., aspirated or unaspirated) and a distinct level at which context-specific information is represented. These data help constrain accounts of sound-structure processing in word production and crucially support the claim that context-independent linguistic information affects language production.
