Further exploration memory bias in compulsive washers

The aim of the present study was to replicate Radomsky and Rachman's findings on memory bias in obsessive-compulsive disorder (OCD), using the same procedure but an increased sample size, more specific control groups, and a full analysis of contamination attribution data. Sixteen OCD-washers, 16 OCD-checkers, 16 social phobic patients and 16 non-anxious controls were presented with 50 'clean' or 'dirty' objects. After this incidental encoding phase, participants were asked to freely recall the objects, to rate their anxiety when almost touching each object, and, finally, to attribute each object to one of the two contamination conditions ('clean' or 'dirty'). Verbal episodic memory was also assessed with the California Verbal Learning Test. The results indicate that, contrary to Radomsky and Rachman's findings, OCD-washers did not differ from the other participants in their memory for 'clean' and 'dirty' objects. However, the OCD-washers recalled more accurately the 'dirty' source of contamination than the 'clean' source. This result was specific to the OCD-washers, and suggests a memory bias for contextually threatening information. The differences between our findings and those published by Radomsky and Rachman's are discussed.     

Of deadly beans and risky stocks: Political ideology and attitude formation via exploration depend on the nature of the attitude stimuli

An attitude formation task examined how conservatives and liberals explore information about novel stimuli and form attitudes towards them. When framed as the BeanFest game, conservatives sampled fewer beans and exhibited a stronger learning asymmetry (i.e., better learning for negative than positive beans) than liberals. This has been taken as strong evidence that conservatives are more sensitive to negative stimuli than liberals. We argue that the learning asymmetry and sampling bias by conservatives is due to framing of the game. In addition to the BeanFest, we framed the game as StockFest (i.e., a stock market game) where participants learned about novel stocks. We replicated the pronounced learning asymmetry for conservatives in the BeanFest game, but found a pronounced learning asymmetry for liberals in the StockFest game. We suggest that conservatives and liberals are equally sensitive to negative stimuli but in different domains.     

A motivation-enhancing treatment to sustain goal engagement during life course transitions

Although theory-driven control striving treatments may sustain motivation for individuals navigating life course transitions, their efficacy during these challenging junctures remains unexamined. In a pre-post randomized field study (n = 316), a novel control striving treatment based on Heckhausen et al.’s (Psychol Rev 117:32–60, 2010) motivational theory of life-span development was administered to young adults making the landmark transition to university. For students who faced obstacles to goal attainment, the motivation-enhancing selective secondary control (SSC) striving treatment (vs. no-treatment) increased performance by 8 % in a two-semester course (74.85 % vs. 66.68 %). Consistent with theory, the SSC treatment-performance linkage was mediated by selective secondary and selective primary control in a hypothesized causal sequence. Findings advance the literature by showing control striving treatments can improve performance for some young adults in transition by promoting adaptive changes in theoretically-derived psychological process variables.     

The development of selective inhibitory control: The influence of verbal labeling

The role of language in the development of selective inhibitory control was examined in four groups: Children aged 7-9 years, children aged 11-13 years, adults aged 20-27 years, and adults aged 62-76 years. We used a modified stop-signal task in which participants inhibited or executed responses based on a visual signal. Response execution and inhibition were assessed by measurement of reaction times (RTs) and error rates to a go signal and RTs to a stop signal. Four task variations were compared in which subjects named (1) the stimulus, (2) the intended action (go/stop), (3) something irrelevant, or (4) nothing. Results showed different developmental trends for response execution and inhibition across the lifespan. Moreover, response execution was faster and more accurate when subjects named the stimulus instead of the intended action. The increase in response accuracy when naming the stimulus was greatest for children. In contrast to expectations, naming the intended action did not influence response inhibition. Overall, these findings suggest that verbal labeling supports the initiation but not the inhibition of actions.     

Stress on the dance floor: the cortisol stress response to social-evaluative threat in competitive ballroom dancers

The social self-preservation theory states that humans have a fundamental motivation to preserve the social self and that threats to the social self perturb biological markers such as cortisol. Five studies were designed to examine the cortisol response to competitive ballroom dancing as a paradigm for real-life social-evaluative threat. Competitive dancing produced substantial increases in cortisol compared to a control day. These increases were not due to the physical strain of dancing and were greater than those found during social-evaluative laboratory stressors. Responses did not habituate across competitions and were mostly elevated under highly focused conditions of threat (couple vs. group competition). These findings support the notion of a social self-preservation system that is physiologically responsive to threats to the social self.     

Adapting to changing memory retrieval demands: Evidence from event-related potentials

This study investigated preparatory processes involved in adapting to changing episodic memory retrieval demands. Event-related potentials (ERPs) were recorded while participants performed a general old/new recognition task and a specific task that also required retrieval of perceptual details. The relevant task remained either constant or changed (predictably or randomly) across trials. Responses were slowed when participants switched from the specific to the general task but not vice versa. Hence, asymmetrical switch costs were observed, suggesting that retrieval preparation is dependent not only on the current retrieval goal but also influenced by recent retrieval attempts. Consistently, over posterior scalp regions ERPs associated with advance preparation were modulated by the preceding task, reflecting increased attentional selection requirements for the general task, and by the foreknowledge about the task sequence. When retrieval demands remained constant, frontal slow-waves elicited by retrieval-cues were more positive going for the specific task, indicating full implementation of a retrieval orientation that allows more efficient retrieval of perceptual details.     

Rating Scales for the Assessment of Empathic Communication in Medical Interviews (REM): Scale Development,Reliability, and Validity

Empathy has been shown to affect the quality of care by enhancing the physician–patient relationship and promoting effective communication. In this study, the newly developed Rating Scales for the Assessment of Empathic Communication in Medical Interviews (REM), designed to assess empathy and confrontation in physician–patient interactions, were subjected to preliminary psychometric testing. Particular attention was paid to face validity, reliability, sensitivity, and practicality. A total of 118 volunteers were asked to assess transcribed interactions between physicians and a standardized patient using the REM. In order to assess the convergent validity of the REM, the Motivational Interviewing Treatment Integrity Code (MITI) and the Behavior Change Counseling Index (BECCI) were used. Factor analysis identified two subscales, reflecting empathy and confrontation. Interrater reliability coefficients for items ranged from r = .82 to .97; Cronbach’s alphas for the two subscales were .89 and .88, respectively. The convergent validity was supported by substantial correlations between the REM scores and the MITI scores and by significant correlations between the REM scores and the BECCI score. The REM demonstrated good psychometric properties suggesting the rating scales might be useful in clinical practice, research endeavors, and medical education. Further research is necessary to assess the test-retest reliability as well as the predictive validity of this instrument.     

Selective attention to emotional faces following recovery from depression

This study was designed to examine attentional biases in the processing of emotional faces in currently and formerly depressed participants and healthy controls. Using a dot-probe task, the authors presented faces expressing happy or sad emotions paired with emotionally neutral faces. Whereas both currently and formerly depressed participants selectively attended to the sad faces, the control participants selectively avoided the sad faces and oriented toward the happy faces, a positive bias that was not observed for either of the depressed groups. These results indicate that attentional biases in the processing of emotional faces are evident even after individuals have recovered from a depressive episode. Implications of these findings for understanding the roles of cognitive and interpersonal functioning in depression are discussed.
