Wiping out memories: New support for a mental context change account of directed forgetting

Costs and benefits of directed forgetting are observed when a between-list instruction to forget List 1 impairs List 1 recall while enhancing List 2 recall. These effects are often ascribed to intentional inhibition of List 1. Contrary to this inhibition account, we found that a forget instruction did not produce costs unless an explicit instruction to concentrate on List 2 was used (Experiment 1). Alternatively, costs may be ascribed to a shift in mental context between encoding and retrieval. Consistent with this mental context-change account, an unexpected task (wiping the computer screen and one's hands) produced costs comparable to a forget instruction, as did as a brief chat between lists (Experiment 2). A number-search task between lists produced neither costs nor benefits (Experiment 3), suggesting that mere distraction is insufficient for inducing mental context change. Our findings support the claim that mental context change underlies both intentional and unintentional forgetting.     

A context-informed approach to the study of negative-feedback seeking in depression

The purpose of the current study was to examine the link between negative-feedback seeking (NFS) and depression using a behavioural task that addressed many of the limitations of existing measures of NFS, to use a remitted-depressive design to determine whether NFS is a temporary or stable feature of depression, and to examine the role of personality and contextual variables (e.g., marital quality, spousal characteristics) in NFS. Using a sample of 59 couples (12 wife currently depressed, 20 wife remitted-depressed, and 27 wife never-depressed), we designed a task that correlated with an established measure of NFS and was able to distinguish between non-depressed and currently depressed wives. Using this behavioural task, we found that NFS is stably associated with depression and that relationship and partner characteristics may protect depressed individuals from engaging in destructive interpersonal patterns.     

A cross-cultural examination of the relation of marital communication behavior to marital satisfaction.

Numerous studies have examined the communication behaviors of Western, primarily North American, couples and have demonstrated a robust and reliable association between marital satisfaction and couple communication. However, there has been relatively less attention given to the generalizability of these findings to non-Western couples. To address this issue, the authors conducted an observational study of marital communication among couples from 3 different cultural groups: 50 White American couples, 52 Pakistani couples in Pakistan, and 48 immigrant Pakistani couples in America. The results show that positive and negative communication behaviors were associated with marital satisfaction within each of the 3 cultural groups. However, the American group's marital satisfaction was more strongly related to marital communication behaviors than was that of the Pakistani group and, to a lesser extent, the immigrant group.     

High involvement HR systems and innovative work behaviour: the mediating role of psychological empowerment,and the moderating roles of manager and co-worker support

Employees’ innovative work behaviour can help firms’ competitiveness. Existing research focuses on several factors, including HR policies, psychological empowerment as well as manager and co-worker support, to explain innovative work behaviour. However, much of this literature analyses just one of these, neglecting how they interact and limiting our understanding of the causes of innovative work behaviour. Synthesizing this work, we develop a novel and holistic framework that examines 1) how high-involvement HR systems are linked via the mediating role of psychological empowerment to innovative work behaviour and 2) how both manager and co-worker support moderate this relationship. Analysing software companies in Pakistan, we use hierarchical linear modelling to assess this framework. We draw on a unique dataset that captures HR policies at the organizational level as well as management and co-worker support, and supervisors’ assessments of individuals’ innovative work behaviour at the individual level. We analyse specific groups of HR practices. Psychological empowerment mediates the relationship between high-involvement HR systems and employees’ innovative work behaviour. Manager and co-worker support moderate the relationship between psychological empowerment and innovative work behaviour. Motivation-enhancing HR practices have a direct effect on innovative work behaviour, whereas ability- and opportunity-enhancing ones are mediated by psychological empowerment.     

Revisiting the relationship between depressive symptoms and marital communication using an experimental paradigm: The moderating effect of acute sad mood

Although research has consistently demonstrated an association between depression and negative marital interactions, it remains unclear whether marital behaviors are specifically associated with depression, above and beyond the effects of a troubled marital relationship. Past research investigating this question has produced inconsistent results. In the present study, we re-examine this question and suggest that one possible reason for past inconsistencies is that across different investigations, samples may have differed in the acute mood state of the depressed partner. It is possible that the marital communication behaviors associated with depression only become evident during acute sad mood states. Seventy-one heterosexual couples who varied on marital satisfaction levels and wife depressive symptoms were videotaped during two marital problem-solving discussions, one of which was preceded by a sad mood induction for the wife. As predicted, results revealed a unique relationship between negative communication patterns and depressive symptoms only when wives had received a sad mood induction. Findings are discussed in light of interpersonal theories of depression.     

Self‐confirmation strivings in depression: An extension to the affective domain using an experimental design

The purpose of the present study was to compare the emotional reactions of depressed and nondepressed individuals to experiences of romantic rejection versus acceptance. We tested our hypotheses in a sample of 28 depressed and 43 nondepressed undergraduate students. In support of self‐consistency theories, the results showed that depressed individuals reported significantly greater negative mood in the romantic acceptance versus rejection condition, while there was no significant difference across the two conditions in the self‐reported mood of nondepressed individuals. Further, symptoms of anxiety mediated the interactive effects of depression status and rejection status on mood. Our findings demonstrate how the responses of depressed individuals to interpersonal feedback contribute to their affective disturbance. Copyright © 2009 John Wiley & Sons, Ltd.     

The relationship between psychological test results and EEG patterns in healthy children

222 children (112 girls and 110 boys) aged 5–16 years with different types of EEG pattern, selected according to well defined normal criteria in order to exclude cerebral lesion elements, were investigated by current child-psychiatric diagnostic methods, including the Wechsler Intelligence Scale for children (WISC), which gave a mean IQ of 116.5. With two so-called tests of organicity (Bender Gestalt Test and Benton's Revised Visual Retention Test) poor performances indicating brain damage were shown in 22% and 24% of the children respectively. Various EEG patterns showed few significant correlations with the test variables. According to clinical judgement "slight symptoms of cerebral dysfunction" was found in some children, but no correlation appeared between such symptoms and poor performance in the psychological tests. The high frequency of defective scores in the Bender and Benton tests in this selected material of healthy children means that these tests cannot be used in clinical work for diagnosing brain injury in individual children. Nor can they be used to throw light on the clinical significance of the different EEG variables studied.
