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.     

Mood regulation in depression: Differential effects of distraction and recall of happy memories on sad mood

Recent research suggests that the recall of positive memories plays an important role in mood regulation. In this study, the authors examined the ability of currently depressed, formerly depressed, and never-depressed participants to regulate sad mood through the recall of positive memories or through distraction. Although improvement in mood was found for all participants in response to distraction, under instructions to recall positive memories, never-depressed participants' moods improved, whereas formerly depressed participants' sad moods remained unchanged. It is important to note that depressed participants exhibited a worsening of their sad moods after recalling positive memories. These results suggest both that depression is associated with an impaired ability to use positive recall to regulate a sad mood and that this impairment continues to be evident following recovery.     

Personality, political skill, and job performance

Based on the socioanalytic perspective of performance prediction [Hogan, R. (1991). Personality and personality assessment. In M. D. Dunnette, L. Hough, (Eds.), Handbook of industrial and organizational psychology (2nd ed., pp. 873–919). Chicago: Rand McNally; Hogan, R., & Shelton, D. (1998). A socioanalytic perspective on job performance. Human Performance, 11, 129–144.], the present study tests whether motives to get along and to get ahead produce greater performance when interactively combined with social effectiveness. Specifically, we investigated whether interactions of the Five-Factor Model constructs of agreeableness and conscientiousness with political skill predict job performance. Our results supported our hypothesis for the agreeableness-political skill interaction. Additionally, after correcting for the unreliability and restricted range of conscientiousness, we found that its interaction with political skill also significantly predicted job performance, although not precisely as hypothesized. Implications of the results and directions for future research are provided.     

Early activity in the lateralized readiness potential suggests prime-response retrieval as a source of negative priming

Negative priming (NP) refers to increased response time (RT) for a probe target that was a distractor in a preceding prime presentation (distractor-target shift, DT), compared to novel targets. The present study used the lateralized readiness potential (LRP) to investigate, in a four-choice identification task, a novel episodic-retrieval explanation of NP introduced by Rothermund, Wentura, and de Houwer (2005). This theory proposes that retrieval reactivates the prime response which interferes with selection of the correct probe response, thereby producing NP. 20 participants responded to pairs of red and blue digits, contingent on the identity of the digit presented in the target color. Behavioral NP involved RT increase by 16 ms. With shift trials (different hands used for prime and probe responses), in the DT condition LRP onset was delayed relative to control. By contrast, earlier LRP onset was observed for DT relative to control with no-shift trials (same hand used for prime and probe responses). Behavioral NP effects showed similar magnitude for shift and no-shift trials. Results support the Rothermund et al. (2005) theory of prime-response retrieval.     

The psychobiology of trait shame in young women: extending the social self preservation theory

OBJECTIVE: The social self preservation theory (SSPT) proposes that social evaluative threat evokes the emotion of shame, which then shapes a coordinated psychobiological response. While this is supported in acute stress studies, there is no data on chronic experiences of shame. DESIGN: We investigated the association of trait shame with activity of the hypothalamic-pituitary-adrenal (HPA) axis, of the sympathetic nervous system (SNS), and regulation of inflammation in n = 56 young women. MAIN OUTCOME MEASURES: Daily profiles of salivary cortisol and alpha-amylase were assessed as indices of HPA axis and SNS activity, respectively. Inflammatory regulation was assessed by lipopolysaccharide-stimulated production and glucocorticoid inhibition of interleukin-6 in vitro. RESULTS: Trait shame was associated with SNS (r = .49; p = .001), but not HPA activity (r = .14; ns). Shame was associated with inflammatory activity (r = .35; p = .006) and glucocorticoid sensitivity (r = -0.43; p = .001). Relationships were not mediated by HPA and SNS activity. CONCLUSIONS: Results support SSPT predictions with respect to chronic shame experience and inflammation. Results further suggest the importance of SNS activation related to shame, and the possibility that HPA activation may be limited acute experiences of shame.     

Neural correlates of rumination in depression

Rumination, or recursive self-focused thinking, has important implications for understanding the development and maintenance of depressive episodes. Rumination is associated with the worsening of negative mood states, greater affective responding to negative material, and increased access to negative memories. The present study was designed to use fMRI to examine neural aspects of rumination in depressed and healthy control individuals. We used a rumination induction task to assess differences in patterns of neural activation during ruminative self-focus as compared with a concrete distraction condition and with a novel abstract distraction condition in 14 participants who were diagnosed with major depressive disorder and 14 healthy control participants. Depressed participants exhibited increased activation in the orbitofrontal cortex, subgenual anterior cingulate, and dorsolateral prefrontal cortex as compared with healthy controls during rumination versus concrete distraction. Neural activity during rumination versus abstract distraction was greater for depressed than for control participants in the amygdala, rostral anterior cingulate/medial prefrontal cortex, dorsolateral prefrontal cortex, posterior cingulate, and parahippocampus. These findings indicate that ruminative self-focus is associated with enhanced recruitment of limbic and medial and dorsolateral prefrontal regions in depression.

Maladaptive coping, adaptive coping, and depressive symptoms: Variations across age and depressive state

Rumination has consistently been found to be associated with the onset and duration of major depressive episodes. Little research, however, has examined factors that may weaken the association between maladaptive coping, such as rumination, and depressive symptoms. In three samples of participants, including 149 never-depressed adolescent girls, 41 never-depressed women, and 39 depressed women, we examined whether generally adaptive forms of coping interacted with generally maladaptive forms of coping to predict depressive symptoms. Age-appropriate measures of coping and depression were administered to participants in each sample. In never-depressed females, maladaptive coping/rumination were more strongly related to depressive symptoms in the presence of lower levels of adaptive coping. The relation between depression and maladaptive coping/rumination was weaker in the context of higher levels of adaptive coping. In contrast, for the depressed females, we found main effects for rumination and adaptive coping, with higher levels of rumination and lower levels of adaptive coping being associated with higher levels of depressive symptoms. The present findings highlight how adaptive coping and maladaptive coping, including rumination, differentially relate to each other and depressive symptoms depending on individuals' current depressive state.
