Acquired equivalence of cues by presentation in a common context in rats

It is well established that humans and other animals may treat two perceptually different cues alike, if the cues have been individually paired with a common antecedent or a common consequence. Recently, Molet et al. (Psychon Bull Rev 18:618–623, 2011) reported evidence for a new form of acquired equivalence in human conditional discrimination, namely context-mediated equivalence. In the present research, using a flavor conditioning procedure, we asked whether rats would show similar context-mediated equivalence to demonstrate that this new form of acquired equivalence is a general phenomenon. Rats experienced two flavor cues A and B each presented either in the same context, X, or each in its own distinctive context, X or Y. Subsequently, the rats experienced B with sucrose in a third context, Z, and then the generalization of conditioning to A was assessed. When tested in Context Z, consumption of A was more marked when A and B had both been presented in the same context than when they had been presented in two different contexts. Thus, importantly, in the absence of the training context, cues that shared a common context at different times came to be treated as equivalent. This represents the first evidence of context-mediated equivalence in a nonhuman species.     

Mood repair and processing mode in depression

Recalling positive autobiographical memories is a powerful emotion regulation strategy that can be used to repair low mood and alleviate negative affect. Unlike healthy individuals, those with current or past depression do not experience an improvement in mood as a consequence of recalling positive memories. We tested whether differences in processing mode might account for this impairment. Following mood induction procedures designed to ensure equivalence of mood state, depressed (n = 35) and recovered depressed (n = 33) participants were instructed to recall a positive memory and focus on it while adopting either an abstract or a concrete mode of processing. Participants in the abstract processing condition experienced no change in mood, while those in the concrete processing condition showed improved mood after memory recall. This research illustrates that the process by which positive autobiographical memories are recalled is important in determining their emotional impact and suggests that psychological interventions for depression may be improved by explicitly targeting processing mode.     

Group-based treatment for internalized stigma among persons with severe mental illness: findings from a randomized controlled trial

Elevated internalized stigma is common and is linked to subjective and objective outcomes for severe mental illness. The authors developed a manualized group-based intervention (Narrative Enhancement/Cognitive Therapy; NECT) to address internalized stigma in severe mental illness. The purpose of the present study was to evaluate the feasibility and effectiveness of NECT. In total, 144 individuals were screened at two sites to evaluate if they met criteria for "elevated" internalized stigma; 39 and were eligible were randomized to NECT or to treatment as usual (TAU) and were assessed at baseline, posttreatment, and 3-month follow-up. Fifteen of the 21 individuals assigned to NECT were classified as "exposed" to treatment. Intent-to-treat analyses found no significant difference between the NECT and TAU groups. A comparison of exposed versus unexposed participants noted trends for exposed participants to have improved more in two aspects of self-stigma as well as insight. We conclude that NECT is feasible and tolerable, but findings did not support the hypothesis that NECT was more effective than TAU, although small sample size and significant dropout may have restricted the ability to detect an effect.     

Elevated responding to safe conditions as a specific risk factor for anxiety versus depressive disorders: evidence from a longitudinal investigation

The current study evaluated the degree to which startle reflexes (SRs) in safe conditions versus danger conditions were predictive of the onset of anxiety disorders. Specificity of these effects to anxiety disorders was evaluated in comparison to unipolar depressive disorders and with consideration of level of neuroticism. A startle paradigm was administered at baseline to 132 nondisordered adolescents as part of a longitudinal study examining risk factors for emotional disorders. Participants underwent a repetition of eight safe-danger sequences and were told that delivery of an aversive stimulus leading to a muscle contraction of the arm would occur only in the late part of danger conditions. One aversive stimulus occurred midway in the safe-danger sequences. Participants were assessed for the onset of anxiety and unipolar depressive disorders annually over the next 3 to 4 years. Larger SR magnitude during safe conditions following delivery of the aversive stimulus predicted the subsequent first onset of anxiety disorders. Moreover, prediction of the onset of anxiety disorders remained significant above and beyond the effects of comorbid unipolar depression, neuroticism, and subjective ratings of intensity of the aversive stimulus. In sum, elevated responding to safe conditions following an aversive stimulus appears to be a specific, prospective risk factor for the first onset of anxiety disorders.     

Validation of a Buddhist Coping Measure Among Primarily Non‐Asian Buddhists in the United States

Researchers have developed scales to measure religious coping among Christians, Jews, Muslims, and Hindus. However, there is no quantitative measure of religious coping for Buddhists. The present study describes the development and initial validation of a scale of Buddhist coping (BCOPE). Eight hundred sixty participants in the United States completed the BCOPE along with demographic information and scales of adjustment to stress. Construct validity of the BCOPE is demonstrated through exploratory and confirmatory factor analyses, which reveals 14 types of Buddhist coping. BCOPE subscales exhibited criterion validity through significant correlations with outcome measures. The BCOPE has incremental validity, predicting adjustment over and above demographic and global religious measures. The research and practical implications of the BCOPE are discussed.     

When local processing increases the appeal of healthy options

People often encounter self-control challenges in complex everyday environments in which objects that promote a given goal (e.g., to eat healthily) are mixed together with objects that obstruct that goal. For example, healthy and unhealthy food choices are often mixed together in restaurant menus. Because local processing facilitates attention to low-level details, we expect that it may play an important role in these complex situations. In the present studies, we test the hypothesis that local processing supports self-control when goal items and temptations are contextually paired. As predicted, our findings revealed that local processing (relative to global processing) increased evaluations of healthy items when those items were presented together with unhealthy items. As hypothesized, this effect of local processing only occurred when healthy and unhealthy foods were presented as complementary – not competing – options, suggesting that local processing may increase evaluations of healthy options by decreasing the extent to which individuals accept environmental cues that healthy and unhealthy foods belong together. These findings support recent research demonstrating that despite strong evidence of the advantages of global processing for self-control, local processing may also support self-control efforts in some important everyday situations.     

Selectively friending: Racial stereotypicality and social rejection

Three studies show that people whose physical features are seen as more (versus less) racially stereotypical are more vulnerable to social rejection and exclusion from those outside their group. In Study 1, which used an online social networking site, Blacks perceived as more physically stereotypical were found to have fewer non-Black friends, compared to less-stereotypical Blacks. In Study 2, which used an experimental paradigm, requests for friendship made to non-Blacks by more-stereotypical Blacks were more likely to be rejected than those made by less-stereotypical Blacks. Finally, in a college dormitory, people judged to have more (vs. less) racially stereotypical physical features were found to interact less often with outgroup members. This work substantiates a growing body of research demonstrating that people who are perceived as more physically stereotypical of their racial group are particularly vulnerable to discriminatory treatment by outgroup members across a variety of life domains.
