Catatonia in affective disorder: new findings and a review of the literature

The historical development of the concept of catatonia in affective disorders and contemporary papers on this topic are reviewed. In addition, data from a current study on the frequency of catatonia in mixed mania are reported. Differences between catatonic and noncatatonic patients with mixed mania are presented and their relevance to clinical practice is discussed.     

Psychological treatment of depression: a review

The available empirical evidence on the efficacy of psychological intervention in depressive disorders is reviewed. No fully adequate study has yet appeared; but there seems sufficient consensus to justify the conclusion that psychological treatment can be effective in alleviating current depressive states and that more complex therapies involving both behavioural and cognitive elements appear the most promising. However, it remains to be seen whether the success of these techniques depends upon the type of depressive disorder manifested; and whether they are applicable across a full range of verbal reasoning ability and socio-economic class.     

Oculomotor control and occipital alpha activity: a review and a hypothesis

Findings relating occipital alpha rhythm with the visual system appear to be difficult to interprete. This is due to the fact that the discrimination between oculomotor control monitored by visual input and monitored by other factors — a distinction which is independent of the presence or absence of visual stimulation — has been widely neglected. A review of the available evidence leads to the conclusion that the inflow of visual information itself has no relation with occipital alpha activity. Blocking occurs only when such information serves also as a monitoring principle in oculomotor position control. Some implications of this hypothesis especially in relation to the concept of alertness and arousal in tasks demanding a high level of visual attention, such as car driving, are discussed.     

Reduced positive future-thinking in depression: Cognitive and affective factors

A pessimistic view of the future is an important feature of depressive thinking, and appears to be influenced at least as strongly by reduced positive expectancies as it is by increased negative expectancies. The present study examined whether reduced positive future-thinking in depression could be accounted for by a reduced capacity to anticipate experiencing pleasure. Depressed and nondepressed participants were asked to generate positive future expectancies using a future-thinking task, and their capacity to anticipate experiencing pleasure in such events was also assessed. Depressed participants provided fewer anticipated positive experiences, a finding which was not accountable for by their reduced pleasure ratings. This reduced positive anticipation was related to levels of depression but not to levels of anxiety. The results are consistent with the view that the lack of anticipated positive experiences in depression arises from a difficulty in accessing mental representations of such experiences.     

Bulimia nervosa: a descriptive and therapeutic study

This study examined a sample of 24 Ss who met strict criteria for a diagnosis of bulimia nervosa. Assessments were made on: (1) demographic characteristics, (2) eating attitudes and behaviour and (3) personality measures. The effectiveness of two types of therapeutic intervention (cognitive-behavioural group therapy vs cognitive-behavioural group therapy plus specific behavioural instruction) was examined in a baseline, therapy intervention, follow-up design.The group was characterized prior to therapy by high N, Depression and Anxiety and low Self-esteem scores compared with control group data. Following therapy, Depression and Anxiety scores were significantly lower and Self-esteem scores higher, whereas N scores remained high. Binge-purging frequencies were significantly reduced in some of the Ss but the reduction could not unequivocally be attributed to the therapeutic interventions. The pattern of results suggested that bulimia nervosa (defined by a binge-purging pattern in association with high neuroticism) should be distinguished from bulimia (defined by a binge pattern not related to purging or high neuroticism) and that DSM-III should be revised to reflect this distinction. A theory is advanced to account for the rapid association of binging and purging in Ss high in neuroticism but not in Ss low in neuroticism.     

Prenatal depression effects on the fetus and newborn: a review

A review of research on prenatal depression effects on the fetus and newborn suggests that they experience prenatal, perinatal and postnatal complications. Fetal activity is elevated, prenatal growth is delayed, and prematurity and low birthweight occur more often. Newborns of depressed mothers then show a biochemical/physiological profile that mimics their mothers' prenatal biochemical/physiological profile including elevated cortisol, lower levels of dopamine and serotonin, greater relative right frontal EEG activation and lower vagal tone. Elevated prenatal maternal cortisol is the strongest predictor of these neonatal outcomes. Moderate pressure massage can alleviate these effects including reducing prematurity.     

Construct accessibility and depression: an examination of cognitive and affective factors

Two studies in which the parameters of construct accessibility in depression were examined are reported. In Experiment 1, depressed and nondepressed subjects were required to name the colors of tachistiscopically presented depressed-content, neutral-content, and manic-content words. Because of the predicted accessibility and interference effects of the depressed-content words, the depressed subjects were expected to demonstrate longer response latencies to these words than to the non-depressed-content words. This response pattern was found for the depressed subjects; the nondepressed subjects did not demonstrate differential response latencies. In Experiment 2, a mood-induction paradigm was used to investigate whether the interference effects obtained in Experiment 1 were due to temporary mood differences between the depressed and nondepressed subjects, or were a function of more stable depression-associated patterns of information processing. Although predicted group differences were obtained on a mood adjective checklist, no effects were found for task performance. These results suggest that transient mood is not a sufficient explanation for the results obtained in Experiment 1. The implications of the present findings for the understanding of both construct accessibility and depression are discussed, and directions for future research are suggested.     

Anxiety sensitivity and major depression: examination of affective state dependence.

An emerging body of research suggests that anxiety sensitivity (AS), and particularly a facet of AS labelled fear of cognitive dyscontrol, is elevated in depressed individuals and is associated with severity of depressed mood. The current prospective study extended previous work by investigating the extent of affective state dependency in the AS-depression relationship in 51 patients who had major depressive episode (MDE) at baseline assessment (Time 1) and did not have MDE 1 year later at follow-up (Time 2). Despite considerable reduction in severity of depressed mood, scores on the Anxiety Sensitivity Index (M=27) remained elevated. Hierarchical regression analysis indicated that, after controlling for both Time 1 and Time 2 depression severity, Time 1 AS continued to predict residual Time 2 AS and increased prediction of variance from approximately 25% to 50%. Time 1 fear of cognitive dyscontrol AS continued to significantly predict Time 2 fear of cognitive dyscontrol AS when Time 2 fear of physical symptoms AS was statistically controlled. A subsample of recovered patients who displayed only minimal depression symptoms was compared to a matched sample of community controls. While the two groups did not significantly differ on level of depressed mood, the formerly depressed patients had significantly higher levels of AS. Implications for a proposed "depression sensitivity" are discussed.     

Age of acquisition and the cumulative-frequency hypothesis: a review of the literature and a new multi-task investigation

Early-acquired words are processed faster than late-acquired words. This is a well-accepted effect within the word recognition literature. Different explanations have been proposed, either localizing the effect of age of acquisition (AoA) in a particular substage of word processing or seeing it as the result of the way in which information is stored and accessed in the brain in general. The cumulative-frequency hypothesis is an example of the latter type of explanation: it states that the total number of times a system has come across a particular stimulus will determine the speed with which the stimulus can be recognized. The present multi-task investigation provides a critical test of the different explanations. Results show that in a variety of word processing tasks the effects of frequency and AoA are highly correlated, and that the impact of AoA is consistently higher than would be expected on the basis of the cumulative-frequency hypothesis. The findings are interpreted as evidence for recent demonstrations of a loss of plasticity in neural networks due to training and/or for mathematical models that describe the growth of the lexico-semantic network as the attachment of new nodes to existing nodes.     

The affective underpinnings of job perceptions and attitudes: a meta-analytic review and integration

Using psychometric meta-analysis, the authors present a quantitative and qualitative review (k = 205, total pairwise N = 62,527) of the literature relating trait and state positive affect (PA) and negative affect (NA) to job-related attitudes, including job satisfaction, organizational commitment, turnover intentions, and dimensions of job burnout. Results indicated substantial correlations, ranging in absolute value from -.17 (PA and turnover intentions; NA and personal accomplishment) to.54 (NA and emotional exhaustion). Correlational results largely were consistent across hypothesized and exploratory moderator conditions. Meta-analytic multiple regression results generally supported the unique contribution of each affect to each attitude variable of interest. Implications and suggestions for future research on emotion-related aspects of job attitudes are discussed.     

Some tests of the hypothesis that obesity is a defence against depression

The hypothesis that obese Ss who lose weight would become depressed was investigated by assessing the relationship between weight loss and changes in Beck Depression Inventory scores. The results failed to support the hypothesis for the group taken as a whole. Nor was it possible to isolate subgroups for whom the hypothesis seemed to hold.     

Attributional style in depression: a meta-analytic review

In this article we report meta-analyses of the relation of attributional styles to depression. In 104 studies involving nearly 15,000 subjects, several attributional patterns had reliable associations with depression scores. For negative events, attributions to internal, stable, and global causes had a reliable and significant association with depression. Studies in which the attribution factors of ability and luck were measured also showed a reliable association with depression. For positive events, attributions to external, unstable, and specific causes were associated with depression. Ability and luck attribution factors for positive events were also associated with depression. The relations for positive events, however, were weaker than the corresponding ones for negative events. In general, these patterns of relations were independent of a number of potential mediators suggested by authors in this literature, including the type of subject studied (psychiatric vs. college student), the type of event about which the attribution is made (real vs. simulated), the depression measure used, or the publication status of the research report. These conclusions are compared with those of other reviews. Implications for attributional models of depression are discussed.     

The affective shift hypothesis: The functions of emotional changes following sexual intercourse

This article develops the Affective Ship Hypothesis, which suggests that women experience positive affective shifts following first‐time intercourse as a means to facilitate a longer‐term, more committed relationship. The hypothesis predicts a negative affective shift in men who pursue a short‐term mating strategy; this shift is hypothesized to function to curtail commitment by motivating the man to terminate the relationship. Study 1 (N= 177) documented sex differences predicted by the affective shift hypothesis. Study 2 (N= 203), using a somewhat different methodology involving reports of presex and postsex feelings, found that men with high numbers of sex partners, but not men with low numbers of partners, experienced a decrease in their partner's physical and sexual attractiveness following first‐time sexual intercourse. In contrast, women, more than men, experienced increases in feelings of love and commitment following first‐time sex.     

Attentional control in depression: A translational affective neuroscience approach

Translational research refers to the application of basic science to address clinical problems and acquire knowledge that can be used to guide and refine clinical practice. This special issue of Cognitive, Affective, & Behavioral Neuroscience seeks to explore and integrate some of the most promising findings offered by recent cognitive and affective neuroscience studies in hopes of filling the gap between basic and applied research, thereby heightening our understanding of vulnerability for depression. The studies presented in this special issue focus specifically on attentional processes. We solicited contributions from leading researchers involved in basic cognitive and neuroscience research investigating processes underlying depression-related disturbances in emotion processing. In this introductory article, we present an integrative overview to demonstrate how these specific contributions might be valuable for translational research.     

The contribution of the insula to motor aspects of speech production: a review and a hypothesis

Based on clinical and functional imaging data, the left anterior insula has been assumed to support prearticulatory functions of speech motor control such as the "programming" of vocal tract gestures. In order to further elucidate this model, a recent functional magnetic resonance imaging (fMRI) study of our group (Riecker, Ackermann, Wildgruber, Dogil, & Grodd, 200) investigated both overt (aloud) and covert (silent) production of highly overlearned word strings ("automatic speech"), based on the suggestion that "inner speech" might provide a "window" into preparatory motor activities (Jeannerod, 1994). As a control condition, subjects were asked to reproduce a nonlyrical tune. In contrast to hemodynamic responses within motor cortex and cerebellum, activation of the intrasylvian cortex turned out to be bound to overt task performance. Rather than prearticulatory processes, these findings suggest the left insula to contribute to the actual coordination of the up to 100 muscles engaged in articulation and phonation. Conceivably, the association of speech production with intrasylvian cortex might have evolved within the framework of phylogenetically older connections between the insula and limbic structures, on the one hand, and nonspeech functions of the upper midline musculature such as swallowing, on the other. Whereas (overt) speech tasks predominantly elicit activation within left anterior insula, reproduction of a nonlyrical tune yielded an opposite response pattern. Conceivably, the opposite distributional pattern of speaking and singing at the level of intrasylvian cortex reflects operation of the two hemispheres across different time domains ("double filtering by frequency theory": left hemisphere=segmental information, right hemisphere=intonation contours of verbal utterances and musical melodies; ). In line with this suggestion, a further study of our group (Ackermann et al., 2001) provided first evidence that differential hemispheric filtering might be bound to insular cortex.
