Coping repertoire: Integrating a new conceptualization of coping with transactional theory

This research develops the construct of coping repertoire, a new trait-based conceptualization of coping based on the number of strategies consumers use in coping with consumer stress. We posit that the number of strategies consumers use is an important determinant of consumers' coping confidence appraisals, a key determinant of consumers' ability to effectively manage stress. In five studies, we establish the importance of this construct and the mechanism through which it influences appraisal. These studies establish the theoretical importance of coping repertoire as an important moderator, and we conclude with a discussion of future research related to this coping perspective.     

Moderating the route angularity effect in a virtual environment: Support for a dual memory representation

Research has shown that increasing the number of turns that a route takes through the environment increases estimates of distance—the route angularity effect. This study tested implications of different memory-based explanations of the route angularity effect within a virtual setting. Participants maneuvered through virtual pathways of varying length that included zero, two, or seven turns. After each set of three paths, they estimated relative path lengths on an analog scale. Results demonstrated that both increasing memory load during navigation and making retrieval more difficult by interpolating another spatial task prior to estimation significantly increased the magnitude of route angularity effects. These results are consistent with the idea that the number of turns is categorically encoded and used as a memory heuristic when fine-grained memory for the route distance is degraded either at encoding or prior to retrieval.     

Superordinate identity and intergroup roommate friendship development

A common ingroup identity promotes positive attitudes and behavior toward members of outgroups, but the durability of these effects and generalizability to relationships outside of the laboratory have been questioned. The present research examined how initial perceptions of common ingroup identity among randomly assigned college roommates provide a foundation for the development of intergroup friendships. For roommate dyads involving students who differed in race or ethnicity, respondents who were low on perceived intergroup commonality showed a significant decline in friendship over-time, whereas those high on perceived commonality showed consistently high levels of friendship. Similarly, participants in these dyads demonstrated a significant decline in feelings of friendship when their roommate was low in perceived commonality but not when their roommate was high in perceived commonality. These effects were partially mediated by anxiety experienced in interactions over-time. The implications of a common identity for intergroup relationship development are discussed.     

Reconsidering the two-second decay hypothesis in verbal working memory

A common belief in the study of short-term memory is that the verbal trace decays around two seconds after it is encoded. This belief is typically assumed to follow from the finding that in immediate serial recall, the time required to rapidly articulate a span-length list is around two seconds. Empirically, this belief is in opposition to a broad set of findings across a number of domains that establish mean decay times to be longer than two seconds. Theoretically, the available computational and mathematical models of immediate serial recall do not address this issue directly, because they typically rely on other mechanisms in addition to decay to account for forgetting. As such, they may show that decay times can be longer than two seconds, but they fail to show that they cannot be as short as two seconds. We address the issue directly and set a lower bound on mean trace decay times, even under the limiting assumption that all forgetting is due to trace decay. We do this by presenting a simple item-based model of trace decay that allows us to estimate values of mean trace duration. For a set of words whose span-length lists can be rapidly articulated in about two seconds, the model offers a conservative estimate for their mean decay times of around four seconds. Both the experimental and theoretical evidence show that items in verbal working memory decay considerably slower than the two-second decay hypothesis claims.     

The Power of Reinforcement: A Review

The Psychological Record -     

Mental toughness, stress, stress appraisal, coping and coping effectiveness in sport

The aim of the present study was to investigate the relationship between mental toughness, stressor appraisal, coping strategies and coping effectiveness among a sample of athletes. Participants were 482 athletes (male n = 305; female n = 177), aged between 16 and 45 years (M age = 20.44 years, SD = 3.98). In support of a priori predictions, mental toughness was associated with stress intensity and control appraisal, but not the type of stressor experienced by athletes. Total mental toughness and its six components predicted coping and coping effectiveness in relation to the self-selected stressor. In particular, higher levels of mental toughness were associated with more problem-focused coping, but less emotion-focused and avoidance coping. Coping effectiveness was influenced by the coping strategy employed by the athletes.     

The expression of c-Fos and colocalisation of c-Fos and glucocorticoid receptors in brain structures of low and high anxiety rats subjected to extinction trials and re-learning of a conditioned fear response

We designed an animal model to examine the mechanisms of differences in individual responses to aversive stimuli. We used the rat freezing response in the context fear test as a discriminating variable: low responders (LR) were defined as rats with a duration of freezing response one standard error or more below the mean value, and high responders (HR) were defined as rats with a duration of freezing response one standard error or more above the mean value. We sought to determine the colocalisation of c-Fos and glucocorticoid receptors-immunoreactivity (GR-ir) in HR and LR rats subjected to conditioned fear training, two extinction sessions and re-learning of a conditioned fear. We found that HR animals showed a marked decrease in conditioned fear in the course of two extinction sessions (16 days) in comparison with the control and LR groups. The LR group exhibited higher activity in the cortical M2 and prelimbic areas (c-Fos) and had an increased number of cells co-expressing c-Fos and GR-ir in the M2 and medial orbital cortex after re-learning a contextual fear. HR rats showed increased expression of c-Fos, GR-ir and c-Fos/GR-ir colocalised neurons in the basolateral amygdala and enhanced c-Fos and GR-ir in the dentate gyrus (DG) in comparison with LR animals. Our data indicate that recovery of a context-related behaviour upon re-learning of contextual fear is accompanied in HR animals by a selective increase in c-Fos expression and GRs-ir in the DG area of the hippocampus.     

Promoting aggression and violence at Abu Ghraib: The U.S. military's transformation of ordinary people into torturers

The torture of detainees at Abu Ghraib has been characterized as an isolated incident and blamed on a few “bad apples.” However, as similar reports of war crimes throughout Iraq continue to surface, it seems increasingly apparent that in the anxious post-9/11 context, the low-level agents who carried out such violence were designed to function in this way. This paper suggests that the U.S. military transformed ordinary soldiers into the cruel and ruthless guards at Abu Ghraib through the use of basic recruitment and training strategies, general authorizations for increased aggression and violence after 9/11, specific authorizations for more aggressive interrogations, a range of pressures and protections, and the dehumanization of prisoners. While the legitimate needs of an effective Army must be preserved, this paper offers several specific ways we might reform the U.S. military and prevent such abuses in the future.     

A comparison of displacement and reinforcer potency for typically developing children

Previous researchers found that individuals with intellectual and developmental disabilities tend to prefer edible over leisure stimuli, although leisure stimuli may still function as reinforcers. We replicated and extended previous research in a 2-part experiment with typically developing children. In Experiment 1, we evaluated 15 children's preference for leisure and edible stimuli. Five of 15 participants preferred edible over leisure stimuli, 3 of 15 participants preferred leisure over edible stimuli, and the remaining 7 of 15 participants did not show a preference for a stimulus class. In Experiment 2, we compared the reinforcer potency of the top-ranked stimulus from each class with 7 of the 8 participants who showed displacement of one stimulus class. Four of 7 participants allocated more responding to the task associated with the top-ranked stimulus and 3 of 7 participants showed no differences in responding to the task regardless of the stimulus rank.     

Individual differences in preference for risky behaviors during courtship

Engaging in risky behaviors is a sexual signalling strategy that men use to procure mates. The present study investigates men’s preferences for engaging in risky behaviors (along with women’s preferences for their male partner’s risky behavior) within dating couples. We investigated associations between relationship length, self-perceived attractiveness, sociosexuality orientation, and preference for risky behaviors in a sample of 256 couples. Results indicated that men had stronger preferences for risky behaviors than their partner’s ideal preference. Furthermore, relationship length was associated with a decline in women’s preference for their partner’s risk-taking, but not men’s preference for their own risk-taking. Self-perceived attractiveness was negatively associated with risk preference, and sociosexuality orientation was not directly related to risk preference. Female preferences for less intense male risky behaviors could reflect the need of paternal investment which is required for offspring care. Decreased male sexual signalling could account for lower preferences of risky behaviors in females who are involved in longer lasting romantic relationships.
