Affective valence and memory in depression: Dissociation of recall and fragment completion.

Depressed (n?=?16) and nondepressed (n?=?16) Ss' memory for affectively valenced words was assessed by an explicit test (free recall) and an implicit test (word fragment completion). Under free-recall instructions, depressed Ss recalled significantly more negatively valenced than positively valenced words, whereas the opposite pattern was observed in nondepressed control Ss. These results replicate those previously reported in the literature. The differential effect of word valence was absent, however, when memory was tested implicitly: Depressed and nondepressed Ss exhibited equivalent priming of positive and negative words. These data are discussed in terms of the J. M. Williams et al (1988) model of depression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Schematic and situational determinants of depressed and nondepressed students' interpretation of feedback.

We examined whether depressed persons' social skill deficits contribute to their negative cognitions and whether this contribution is independent of their negative schemata. Depressed (n?=?60) and nondepressed (n?=?60) Ss engaged in group discussions. We assessed Ss' social competence schemata with a questionnaire and Ss' actual level of social competence in the discussion through objective ratings made by codiscussants and outside observers. We found that independently of their negative schemata, depressed Ss' social skill deficits explained a significant portion of the variance in their more negative interpretation of feedback (relative to nondepressed Ss'). This suggests that real deficits in depressed persons' performance compound the effects of their negative schemata and further contribute to their negative cognitions. We also further explored findings by B. M. Dykman et al (see record 1989-18948-001) and P.M. Lewinsohn et al (see record 1980-12088-001).

Attributional, perceptual, and affective responses to depressed and nondepressed marital partners.

Husbands of wives with (n?=?22) or without (n?=?23) a history of a depressive disorder indicated their attributions about and affective reactions to real and hypothetical positive and negative events occurring to their wives, rated their wives on personality traits categorized as depression-related and depression-neutral, and reported their own marital satisfaction. Husbands of depressed, relative to nondepressed, wives made more dispositional attributions, reported more negative affect in reaction to negative events, and indicated less marital satisfaction. Depressed wives were rated more negatively on both depression-related and depression-neutral personality traits. Results are interpreted as suggesting that spouses of depressed wives have a generalized negative view of their wives, which may also be operating within distressed marriages.

Depression in multiple sclerosis: Relationship to working memory capacity.

Recent research has shown that depression in multiple sclerosis (MS) is associated with deficits on cognitively demanding tasks. One explanation for this relationship is that depressed NIS patients may have reduced working memory capacity. The present study was designed to test this hypothesis. Depressed NIS patients were compared with nondepressed MS patients and nondepressed healthy controls on a task of working memory capacity (reading span) and a short-term memory task not taxing working memory capacity (word span). In support of the capacity-reduction model, compared with the nondepressed groups, depressed MS patients performed significantly worse on reading span but not on word span. Additionally, reading span was significantly correlated with capacity-demanding tasks shown to be impaired in depressed NIS patients in previous reports. Results suggest that depressed MS patients are characterized by limited working memory capacity and that the central executive component of the working memory system may be most affected.

Depressed mood in multiple sclerosis: Relationship to capacity-demanding memory and attentional functioning.

Because it is theorized that depression results in reduced available attentional capacity that, in turn, can explain the impaired performance on capacity-demanding tasks in depressed individuals, the authors predicted that multiple sclerosis (MS) patients with depressed mood would have difficulty with these types of tasks. Twenty depressed mood MS participants were compared with 41 nondepressed mood MS participants and 8 nondepressed mood controls on 5 attentional capacity-demanding clinical memory and attentional tasks and 3 tasks with minimal capacity demands. Depressed mood MS patients performed significantly worse than both nondepressed mood groups on the 3 speeded capacity-demanding attentional measures but not on any of the tasks requiring few capacity demands, supporting the authors' predictions. The possibility that the impaired performance of depressed mood MS patients on speeded attentional tasks was mediated by reduced verbal working memory capacity, impaired deployment of executive strategies that access working memory capacity, or psychomotor slowing is explored.

Interpersonal betrayal and cooperation: Effects on self-evaluation in depression.

Assessed the effect of interpersonal betrayal and cooperative social interaction on self-evaluation processes among 54 female undergraduates scored as depressed or nondepressed on the Self-Rating Depression Scale. Depressed Ss who experienced interpersonal betrayal in a prisoner's dilemma game were more critical of their performance on a subsequent task than were nondepressed Ss or depressed Ss who had experienced a cooperative interaction. Depressed Ss in the betrayal condition also behaved more aggressively toward their betraying partner than did nondepressed betrayed Ss. Depressed Ss were more critical of their own personality characteristics than were nondepressed Ss, regardless of condition. Results suggest that some negative cognitive schema among depressed persons may be altered by interpersonal factors, although it is not clear whether such effects are secondary to increases in self-criticism after conflict or to decreases in self-critical tendencies after positive interaction. Researchers are urged to use multiple, diverse measures of self-evaluation in future efforts to study variability in self-appraisal.

Episodic memory functioning in a community-based sample of old adults with major depression: Utilization of cognitive support.

Community-based samples of old adults with current major depression (n?=?17; mean age 83.29 yrs) and healthy old adults (n?=?51; mean age 83.29 yrs) were examined on a variety of episodic recall and recognition tasks. Results indicate depression-related deficits in recall that were reduced but not eliminated, in recognition. Control Ss were able to utilize cognitive support in the form of more study time and item organizability in free recall, whereas depressed Ss were not. However, both groups showed equal gains from the provision of category cues and beneficial effects of prior knowledge and more study time in recognition. Results suggest that depression results in deficits in effortful, elaborate processes at encoding and retrieval and that old age depression is associated with a reduced ability to utilize cognitive support to improve episodic memory. Depressed older adults appear to require cognitive support at both encoding and retrieval to demonstrate memory facilitation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Evaluating the continuity of symptomatology between depressed and nondepressed individuals.

Debate is contentious concerning whether depression should be viewed as a distinct category or as a continuum including overlapping normal and clinical phenomena. A nonparametric item response model was used to evaluate whether the probability of expressing individual symptoms differed between nondepressed and clinically depressed adults experiencing similar levels of overall severity. Even though depressed and nondepressed individuals were equated in terms of overall severity, differences on specific symptoms emerged. Depressed mood, anhedonia, and suicidality were more likely to be expressed in depressed than in nondepressed individuals, whereas hypochondriasis and middle insomnia were more likely to be expressed in nondepressed individuals at similar levels of severity. Such differences are inconsistent with the view of depression as a simple continuum. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Depression, interpersonal standard setting, and judgments of self-efficacy.

Investigated the relationship between standard setting and judgments of self-efficacy in the domain of interpersonal functioning for depressed and nondepressed Ss. Consistent with a self-control model of depression, a large discrepancy between personal standards and judgments of personal efficacy for performance was postulated to be related to depression. Undergraduate students who scored above 13 on 2 administrations of the Beck Depression Inventory composed the depressed group. 39 depressed and 39 nondepressed students rated their minimal standards for adequate interpersonal performance, its importance to them, and their judgments of self-efficacy for the same tasks, using the Interpersonal Concerns Questionnaire. Depressed Ss showed a larger discrepancy between strength of interpersonal standards and strength of self-efficacy than did normal Ss. Depressed Ss expressed a lower strength of self-efficacy than did nondepressed Ss, but they did not differ on their interpersonal standards. Importance and the strength for standards are consistent with recent extensions of P. M. Lewinsohn's (1974) model of depression, which suggests that disruptions in self-evaluation are related to lowered judgments of self-efficacy for depressed Ss.

Attributional style among depressed patients.

Male depressed unipolar patients (n?=?30) were more likely to attribute bad outcomes to internal, stable, and global causes than were nondepressed schizophrenics (n?=?15) and nondepressed medical patients (n?=?61). Also, the depressed patients were more evenhanded in their attributions for good and bad events than the other patients. These results support the existence, in clinical depression, of the depressive attributional style postulated by the reformulated learned helplessness model and indicate that it is not a general characteristic of psychopathology.

Depression and the magnification of failure.

Theory and observation suggest that depressed individuals minimize the importance of successes while magnifying the significance of failures. An experimental test of these predictions was performed. Depressed and nondepressed college students were given predetermined success or failure feedback on an ostensible test of social perceptiveness. Prior to taking the test, subjects indicated the degree to which they possessed various personality traits (including social perceptiveness) and the importance of those traits. After subjects received the feedback, the trait scales were readministered. The results indicated that depressed subjects inflated the importance of social perceptiveness after learning they had done poorly on a test presumed to measure that trait. In contrast, nondepressed subjects inflated the importance of social perceptiveness after succeeding on the test. Depressed subjects also displayed a tendency to overgeneralize from the social perceptiveness test results by lowering their estimates of their general proficiency following failure. The results suggest that depressed individuals evaluate personal feedback in a manner that tends to be self-derogating. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A hybrid computational model for ultrasound phased-array heating in presence of strongly scattering obstacles

BACKGROUND: Studies using electroencephalogram (EEG) measures of activation asymmetry have reported differences in anterior asymmetry between depressed and nondepressed subjects. Several studies have suggested reciprocal relations between measures of anterior and posterior activation asymmetries. We hypothesized that depressed subjects would fail to show the normal activation of posterior right hemisphere regions in response to an appropriate cognitive challenge. METHODS: EEG activity was recorded from 11 depressed and 19 nondepressed subjects during the performance of psychometrically matched verbal (word finding) and spatial (dot localization) tasks. Band power was extracted from all epochs of artifact-free data and averaged within each condition. Task performance was also assessed. RESULTS: Depressed subjects showed a specific deficit in the performance of the spatial task, whereas no group differences were evident on verbal performance. In posterior scalp regions, nondepressed controls had a pattern of relative left-sided activation during the verbal task and relative right-sided activation during the spatial task. In contrast, depressed subjects failed to show activation in posterior right hemisphere regions during spatial task performance. CONCLUSIONS: These findings suggest that deficits in right posterior functioning underlie the observed impairments in spatial functioning among depressed subjects.     

Processing of ambiguous and unambiguous feedback by depressed and nondepressed college students: Schematic biases and their implications for depressive realism.

Explored schematic processing as a mechanism for predicting (a) when depressed Ss would be negative relative to nondepressed Ss and (b) when depressed and nondepressed Ss would show biased or unbiased (i.e., "realistic") processing. Depressed and nondepressed Ss performed multiple trials of a task under conditions in which the 2 groups held either equivalent or different schemas regarding this task. Ss received either an unambiguous or objectively normed ambiguous feedback cue on each trial. In full support of schematic processing, depressed Ss showed negative encoding relative to nondepressed Ss only when their schemas were more negative, and both depressed and nondepressed Ss showed positively biased, negatively biased, and unbiased encoding depending on the relative feedback cue-to-schema match. Depressed and nondepressed Ss' response latencies to unambiguous feedback also supported the occurrence of schematic processing. We discuss the methodological, treatment, and "realism" implications of these findings and suggest a more precise formulation of Beck's schema theory of depression.

Effects of Subclinical Depression and Aging on Generative Reasoning About Linear Orders: Same or Different Processing Limitations?

The performance of older adults and depressed people on linear order reasoning is hypothesized to be best explained by different theoretical models. Whereas depressed younger adults are found to be impaired in generative inference making, older adults are well capable of making such inferences but exhibit problems with working memory (Experiments 1 and 2). Restriction of the available study time impairs reasoning by nondepressed control participants and. as such, proves to be a good model of older adults' but not depressed participants' limitations (Experiment 3). These results are replicated comparing depressed and older participants with a control group in the same study, providing increased power and linking the results to additional control measures of processing speed and working memory (Experiment 4).

Body image, physical attractiveness, and depression.

224 17–63 yr olds completed measures of self-perceived physical attractiveness and depression, and static full-body videotapes of Ss were assessed by objective raters, to investigate the relationship between Ss' body image, rated physical attractiveness, and depression. Measures included the Body-Self Relations Questionnaire, Center for Epidemiologic Studies Depression Scale (CES-D), a body parts satisfaction scale, and a self-labeling depression scale. Ss were classified as depressed (n?=?35) or nondepressed (n?=?42) on the basis of conjunctive criteria of self-labeling and extreme groups on the CES-D. It was hypothesized that (1) depressed Ss would report being less satisfied with their body parts and physical appearance and would regard themselves as less physically attractive than would nondepressed Ss, (2) objective raters would perceive depressed Ss as less physically attractive than nondepressed Ss, and (3) depressed Ss would distort their degree of physical attractiveness and perceive themselves to be less attractive than objective raters regarded them. Results indicate that, as hypothesized, depressed Ss were less satisfied with their bodies and saw themselves as less physically attractive than nondepressed Ss. These groups did not differ with respect to observer-rated physical attractiveness. Support was obtained for A. T. Beck's (1973, 1976) cognitive hypothesis that depressed persons negatively distort their body images; however, results also indicate substantial positive distortion among nondepressed Ss.

Rumination and impaired resource allocation in depression.

Depression is characterized by a range of cognitive deficits that theorists posit are due to the resource capturing properties of rumination. The present study was designed to examine the relation between rumination and resource allocation in depression. Twenty-five depressed and 25 nondepressed participants completed a modified dual-task version of the recency-probes task, which assesses the controlled allocation of cognitive resources by comparing performance across low- and high-interference conditions. In low-interference conditions, participants performed either the recency-probes task or a tracking task, which required participants to track specific stimuli across trials (i.e., no dual-task interference). In the high-interference condition, participants performed both the recency-probes task and the tracking task, which required the controlled allocation of resources to resolve dual-task interference. Depressed participants performed significantly worse than did their nondepressed counterparts in only the high-interference condition; performance of the 2 groups was comparable in the low-interference conditions. Furthermore, the degree to which depressed participants were impaired in the high-interference condition was correlated .74 with rumination. These findings suggest that an association between rumination and impairments in resource allocation underlies the cognitive difficulties experienced by depressed individuals.

Impairment in risk-sensitive decision-making in older suicide attempters with depression.

Suicidal behavior is a potentially lethal complication of late-life depression. In younger adults, suicide has been linked to abnormal decision-making ability. Given that there are substantial age-related decreases in decision-making ability, and that older adults experience environmental stressors that require effective decision-making, we reasoned that impaired decision-making may be particularly relevant to suicidal behavior in the elderly. We thus compared performance on a probabilistic decision-making task that does not involve working memory (“Cambridge Gamble Task”) in four groups of older adults: (1) individuals with major depression and a history of suicide attempt (n = 25), (2) individuals with major depression with active suicidal ideation but no suicide attempt (n = 13), (3) individuals with major depression without suicidality (n = 35), and (4) nondepressed control subjects (n = 22). There was a significant effect of group on quality of decision-making, whereby the suicide attempters exhibited poorer ability to choose the likely outcome, compared with the nonsuicidal depressed and nondepressed comparison subjects. There were no group differences in betting behavior. The suicide attempters differed in several aspects of social problem-solving on a self-report scale. Quality of decision-making was negatively correlated with the score on the impulsive/careless problem-solving subscale. These data suggest that older suicide attempters have a deficit in risk-sensitive decision-making, extending observations in younger adults. More specifically, older suicide attempters seem to neglect outcome probability and make poor choices. These impairments may precipitate and perpetuate suicidal crisis in depressed elders. Identification of decision-making impairment in suicidal elders may help with designing effective interventions. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Effects of self-esteem manipulation on arousal and reactions to sad models in depressed and nondepressed college students.

24 depressed and 24 nondepressed college students were given spurious feedback, either positive or negative, about the results of personality tests. They then watched a film of an intensive encounter group. Psychophysiological reactions to both feedback and observation of sad film models were recorded. Depressed Ss showed greater arousal than nondepressed Ss only after negative feedback. Depressed Ss reacted emotionally to the sad models after negative feedback; nondepressed Ss, after positive feedback. Arousal results indicate that depressed Ss were particularly reactive to a "loss" of self-esteem. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
