Renewal of fear and avoidance in humans to escalating threat: Implications for translational research on anxiety disorders

Exposure-based treatment for threat avoidance in anxiety disorders often results in fear renewal. However, little is known about renewal of avoidance. This multimodal laboratory-based treatment study used an ABA renewal design and an approach–avoidance (AP–AV) task to examine renewal of fear/threat and avoidance in twenty adults. In Context A, 9 visual cues paired with increases in probabilistic money loss (escalating threats) produced increases in ratings of feeling threatened and loss expectancies and skin-conductance responses (SCR). During the AP–AV task, a monetary reinforcer was available concurrently with threats. Approach produced the reinforcer or probabilistic loss, while avoidance prevented loss and forfeited reinforcement. Escalating threat produced increasing avoidance and ratings. In Context B with Pavlovian extinction, threats signaled no money loss and SCR declined. During the AP–AV task, avoidance and ratings also declined. In a return to Context A with Pavlovian threat extinction in effect during the AP–AV task, renewal was observed. Escalating threat was associated with increasing ratings and avoidance in most participants. SCR did not show renewal. These are the first translational findings to highlight renewal of avoidance in humans. Further research should identify individual difference variables and altered neural mechanisms that may confer increased risk of avoidance renewal.     

Where (who) are collectives in collectivism? Toward conceptual clarification of individualism and collectivism

In psychological research on cultural differences, the distinction between individualism and collectivism has received the lion's share of attention as a fundamental dimension of cultural variation. In recent years, however, these constructs have been criticized as being ill-defined and "a catchall" to represent all forms of cultural differences. The authors argue that there is a conceptual confusion about the meaning of ingroups that constitute the target of collectivism. Collectives are rarely referred to in existing measures to assess collectivism. Instead, networks of interpersonal relationships dominate the operational definition of "ingroups" in these measures. Results from a content analysis of existing scales support this observation. To clarify and expand the individualism-collectivism distinction, a theoretical framework is proposed that draws on M. B. Brewer and G. Gardner's (1996) conceptualization of individual, relational, and collective selves and their manifestation in self-representations, beliefs, and values. Analyses of data from past studies provide preliminary support for this conceptual model. The authors propose that this new theoretical framework will contribute conceptual clarity to interpretation of past research on individualism and collectivism and guide future research on these important constructs.     

The importance of being we: human nature and intergroup relations

The author discusses the nature of in-group bias and the social motives that underlie ethnocentric attachment to one's own membership groups. Two common assumptions about in-group bias are challenged: that in-group positivity necessitates out-group derogation and that in-group bias is motivated by self-enhancement. A review of relevant theory and research on intergroup relations provides evidence for 3 alternative principles: (a) in-group attachment and positivity are primary and independent of out-groups, (b) security motives (belonging and distinctiveness) underlie universal in-group favoritism, and (c) attitudes toward out-groups vary as a function of intergroup relationships and associated threats to belonging and distinctiveness     

Self-control relies on glucose as a limited energy source: willpower is more than a metaphor

The present work suggests that self-control relies on glucose as a limited energy source. Laboratory tests of self-control (i.e., the Stroop task, thought suppression, emotion regulation, attention control) and of social behaviors (i.e., helping behavior, coping with thoughts of death, stifling prejudice during an interracial interaction) showed that (a) acts of self-control reduced blood glucose levels, (b) low levels of blood glucose after an initial self-control task predicted poor performance on a subsequent self-control task, and (c) initial acts of self-control impaired performance on subsequent self-control tasks, but consuming a glucose drink eliminated these impairments. Self-control requires a certain amount of glucose to operate unimpaired. A single act of self-control causes glucose to drop below optimal levels, thereby impairing subsequent attempts at self-control.     

Familiar other-race faces show normal holistic processing and are robust to perceptual stress

Other-race individuals are remembered more poorly and receive less holistic/configural processing than same-race individuals, at least when faces are novel. Here, we examine the amelioration of these effects with familiarity, using distinctiveness-matched Caucasian and Asian stimulus sets. We confirmed a cross-race deficit for upright faces following a single encoding trial, which disappeared rapidly with practice on a small set of other-race 'friends' and did not re-emerge when perceptual processing was put under stress (presentation in the periphery). We also examined holistic/configural processing for familiarised faces using the peripheral inversion effect (McKone, 2004 Journal of Experimental Psychology: Learning, Memory, and Cognition 30 181 - 197). A test for faces and nonface objects (dogs) confirmed the validity of this technique as providing a direct measure of holistic processing; we then showed that, after 1 h of training, holistic processing was as strong for other-race as same-race faces. We conclude that practice with other-race individuals can rapidly engage normal face-processing mechanisms.     

The Compensatory Role of Implementation Intentions for Young Adults with Low Working Memory Capacity

Many factors improve prospective memory performance both inside and outside of the laboratory, including the detailed planning of the situational cue and intended action (i.e., implementation intentions). In the current study, we obtained measures of working memory capacity and laboratory event‐based prospective memory performance in college‐aged adults. Half of our participants formed an implementation intention in the prospective memory task. Because of evidence that implementation intentions increase the encoding/retrieval efficiency of the prospective memory, it was predicted that forming an implementation intention would serve as a compensatory strategy for those with low working memory ability. Our results supported this hypothesis in that working memory capacity no longer correlated with prospective memory performance when participants employed an implementation intention encoding strategy. These findings suggest that implementation intentions may be an effective way for individuals with low working memory capacity to improve their performance in an attentionally demanding prospective memory task.

Memorial Monitoring and Control: How Confidence and Social and Financial Consequences Affect Eyewitnesses' Reporting of Fine‐Grain Information

Research suggests that accessible coarse‐grain (i.e. general) information is sometimes under‐reported in memory accounts. In two experiments, socially motivating conditions were manipulated to determine whether, and under what contexts, coarse‐grain information is avoided because eyewitnesses are motivated to be specific and willing to risk accuracy. In Experiment 1, response privacy (private, public) and audience (high authority, low authority) were manipulated. Response privacy and penalty for inaccurate reporting (penalty, no penalty) were manipulated in Experiment 2. Across both experiments, eyewitnesses' confidence estimation (i.e. monitoring) was effective, suggesting that coarse‐grain information is under‐reported through poor decision making (i.e. control). Eyewitnesses avoided coarse‐grain information because they sometimes displayed a bias towards reporting fine‐grain information. This bias was more apparent, and coarse‐grain information avoiding more likely, when the perceived consequences for reporting were minimal (i.e. when in private in Experiment 1 and when no penalty for inaccuracy was imposed in Experiment 2).

Imaging the medial temporal lobe: exploring new dimensions

Cognitive scientists have used developments in functional imaging to explore the role of the medial temporal lobe (MTL) in memory formation. Lesion studies have suggested that separate MTL subregions make distinct contributions to memory. Functional imaging of these distinct contributions, however, remains a challenge, because the proximity of the MTL substructures tests the spatial resolution limits of current techniques. Recent findings using electrophysiological measures of neural activity highlight the importance of using information from other imaging modalities. Integrating the different modalities of neuroimaging with lesion studies, and, further, combining modalities within experiments, will provide new insights into the function of MTL subregions.

Threat-related processing supports prospective memory retrieval for people with obsessive tendencies

Obsessive-compulsive disorder can result in a variety of deficits to cognitive performance, including negative consequences for attention and memory performance. The question addressed in the current study concerned whether this disorder influenced performance in an event-based prospective memory task. The results from a subclinical population indicated that, relative to non-anxious controls and mildly depressed controls, people with obsessive-compulsive tendencies (washing compulsions) incur decrements in remembering to respond to cues related to a neutral intention (respond to animals). This deficit was ameliorated by giving the subclinical group an intention about a threat-related category (respond to bodily fluids) and cueing them with concepts that they had previously rated as particularly disturbing to them. Thus, their normal attentional bias for extended processing of threat-related information overcame their natural deficit in event-based prospective memory.
