Depression and perceived reinforcement: A reconsideration.

Evidence for the depressed S's hypersensitivity to any feedback about his performance and for the reversibility of depression-based perceptual deficits suggests that the depressed S can perceive response–reinforcement contingencies correctly, but only if given unassailable evidence of the efficacy of his actions. A high rate of response-contingent reinforcement is one instance of such evidence. The authors predicted that depressed Ss would misperceive skill task rewards under low- but not under high-reinforcement conditions. Changes in verbalized expectancies of success on skill and chance tasks at either 50 or 75% reinforcement rate were compared for 20 depressed and 20 nondepressed college students. Contrary to prediction, depressed Ss in no way differed from the nondepressed on the skill task at 50% reinforcement, and they produced larger expectancy changes on the chance task than did nondepressed Ss at 75% reinforcement. Results argue against the view that the depressed person misperceives response reinforcement contingencies, and they suggest instead that the depressed person overgeneralizes from any experience of success or failure in forming expectations for future successes.

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.

Cognitive theory and the generality of pessimism among depressed persons.

38 depressed (as measured by the Beck Depression Inventory) and 52 nondepressed college students were given a series of anagrams to solve. A 1-chance subgroup was informed that they would win a free movie ticket if they were successful in the task. A 2nd-chance subgroup received the same instructions as the 1-chance subgroup but were also informed that if they failed, they would have another opportunity in a different, undefined task. Ss were subdivided into success and failure subgroups that either succeeded at or failed the anagram task. Immediately afterwards, Ss reported their emotional state on the Multiple Affect Adjective Check List. Depressed Ss reported greater depression, anxiety, and hostility than nondepressed Ss in the 1-chance condition but not in the 2nd-chance condition; this interaction occurred independent of Ss' success or failure in the task. Results are viewed as indicating that current cognitive theories about the generality of pessimism in depression are incomplete. An explanation of the results in terms of the saliency of future reward opportunity is suggested as a basis for further study.

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)     

Depressive self-presentation: Beyond self-handicapping.

An experiment was conducted to examine the notion that depressives' responses would reflect a protective self-presentation style (M. G. Hill et al, 1986), the underlying goal of which would be the avoidance of future performance demands and potential losses in self-esteem. In this study, depressed and nondepressed Ss were asked to perform a relatively simple visual–motor task. Half of the depressed and half of the nondepressed Ss were told that if they were successful at the task, they would be asked to perform a 2nd similar task. The remaining Ss were given no such expectation of future performance. We predicted and found that depressed compared with nondepressed Ss strategically failed at the task when presented with the possibility of future performance and further losses in esteem. Moreover, this strategic failure was associated with some costs; depressed, future performance expectancy Ss experienced more discomfort or negative affect as a result of their performance. The relationship between this depressive self-presentation and self-handicapping strategies is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Decision style in depression: The contribution of perceived risks versus benefits.

The present study investigated the contribution of cognitive and social factors to the decision style of depressed persons. During two sessions (Times 1 and 2), depressed and nondepressed college students were asked to imagine themselves making decisions about common life situations that afforded potential benefits but that also entailed potential risks. The decision scenarios varied in content. For each situation, subjects evaluated several potential risks and benefits and indicated what decisions they would make. In both sessions and for all types of decision scenarios, the depressed assigned greater weight to risks than did the nondepressed. Furthermore, for decisions about initiating social contact and establishing intimacy, the depressed expressed a greater reluctance to take the target action than did the nondepressed, and their perceptions of risks appeared to influence their estimated decisions more strongly. The Time 2 study also revealed that most of these differences applied equally when individuals were thinking about themselves or another person. However, risk perceptions were found to contribute more to the decision style of the depressed, relative to the nondepressed, only when their thoughts were focused on themselves and not when their thoughts were focused on another person.

Universal versus personal helplessness in depression: Belief in uncontrollability or incompetence?

The learned helplessness model of depression predicts that depressed individuals believe outcomes are more response independent than do nondepressed individuals in a skill situation. The present study assessed whether depressives' cognitive distortions are specific to their belief about their own skilled action or are a result of a general belief in uncontrollability in the world. Changes in expectancies following success and failure in skill and chance tasks were examined in 32 depressed and 32 nondepressed college students who either performed themselves or observed a confederate perform a pair of tasks. In the skill task, depressed Ss showed significantly smaller changes in expectancy than nondepressed Ss when estimating the probability of their own success. In contrast, depressed and nondepressed Ss did not differ when estimating the probability of another person's success on the identical skill task. It is inferred that depressed individuals view themselves as helpless in a skilled situation but do not view the situation itself as uncontrollable. Results are discussed in terms of the reformulated learned helplessness model. (52 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Selective recall of positive and negative feedback, self-control behaviors, and depression.

Tested 2 sets of hypotheses, derived from cognitive–behavioral theories of depression, that (a) compared to a sample of nondepressed controls, depressed Ss would underestimate the frequency of reinforcement and overestimate the frequency of punishment received during an ambiguous laboratory task; and (b) when given the opportunity to self-reinforce or self-punish, depressed Ss would self-reinforce less often and self-punish more often than controls. Three of these predictions were supported. In an experiment with 24 depressed and 21 nondepressed undergraduates (Beck Depression Inventory), depressed Ss recalled less positive and more negative feedback than controls. As expected, these differences were significant only at a high rate of reinforcement and at a low rate of punishment. In the latter condition, however, depressed Ss were accurate in their recall, while nondepressed Ss underestimated the frequency of negative feedback. Depressed Ss self-reinforced less often than controls, but there were no differences in rates of self-punishment. Implications for cognitive and behavioral theories of depression are discussed.

Attributional and social comparison processes in depression.

In this study we examined the consequences for depressed and nondepressed individuals of receiving comparison feedback regarding their causal understanding of an event. Specifically, the effects of similar, dissimilar, or no-comparison feedback on depressed and nondepressed subjects' evaluations of the comparison other and on their feelings about themselves were investigated. Because the reduction of uncertainty about one's conception of social reality is a major motive underlying social-comparison processes, we expected that depressed individuals, who are assumed to have experienced heightened uncertainty associated with frequent exposure to uncontrollable life events, would be more motivated to engage in social comparison and would be more sensitive to social-comparison feedback. Results generally were consistant with this reasoning. The implications of the results in terms of the development and maintenance of depression were discussed.

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)     

Selective attention and clinical depression: Performance on a deployment-of-attention task.

Clinically depressed and nondepressed individuals completed a deployment-of-attention task developed by I. H. Gotlib, A. L. McLachlan, and A. N. Katz (1988). Results indicated that the clinically depressed individuals perform the task in an unbiased fashion, attending equally to positive-, negative-, and neutral-content stimuli. In contrast, the nondepressed individuals demonstrated a "protective" bias against the perception of negative stimuli by avoiding such material in favor of positive or neutral stimuli. Overall, the results of this study suggest that clinically depressed individuals do not show an attentional bias toward negative information, but rather, fail to demonstrate the positive or protective bias that is evident in nondepressed individuals.

Interpersonal and impersonal problem-solving skills in mildly and clinically depressed university students.

Administered the Beck Depression Inventory and the State-Trait Anxiety Inventory to 20 nondepressed and 20 depressed university students and 8 nondepressed and 10 depressed university students being treated at a university counseling service. Ss were then tested on the Means–Ends Problem-Solving Procedure (a measure of interpersonal problem-solving ability) and the anagram task used in the investigations of learned helplessness (a measure of impersonal problem-solving ability). All Ss were administered the Clarke Institute of Psychiatry version of the Vocabulary subscale of the WAIS. A significant negative correlation was found between depression and interpersonal problem-solving ability, while only anxiety was correlated with anagram performance. Differences between groups were found only in interpersonal problem-solving performance. Nondepressed Ss performed significantly better than the other 3 groups, while depressed counselees obtained the lowest scores on the interpersonal measures. No relationship was found between performance on the anagram task and performance on the Means–Ends Problem-Solving Procedure. Results are consistent with predictions generated by interpersonal theories of depression, but they raise questions about the validity of the learned helplessness model as an analog of clinical depression.

Frontolimbic Response to Negative Feedback in Clinical Depression.

Functional neuroimaging suggests that limbic regions of the medial frontal cortex may be abnormally active in individuals with depression. These regions, including the anterior cingulate cortex, are engaged in both action regulation, such as monitoring errors and conflict, and affect regulation, such as responding to pain. The authors examined whether clinically depressed subjects would show abnormal sensitivity of frontolimbic networks as they evaluated negative feedback. Depressed subjects and matched control subjects performed a video game in the laboratory as a 256-channel EEG was recorded. Speed of performance on each trial was graded with a feedback signal of A, C, or F. By 350 ms after the feedback signal, depressed subjects showed a larger medial frontal negativity for all feedback compared with control subjects with a particularly striking response to the F grade. This response was strongest for moderately depressed subjects and was attenuated for subjects who were more severely depressed. Localization analyses suggested that negative feedback engaged sources in the anterior cingulate and insular cortices. These results suggest that moderate depression may sensitize limbic networks to respond strongly to aversive events. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of failure on the self-esteem of depressed and nondepressed subjects.

Hypothesized that depressed Ss would show greater negative change in self-esteem in response to failure than nondepressed Ss, and investigated the relationship between lability and stability in mood and susceptibility of self-esteem to failure. 24 depressed and 24 nondepressed Ss completed daily mood ratings for 1 wk. and were categorized into stabile and labile groups. Each S was given a puzzle-solving task on which a 25, 50, or 75% failure condition was possible. Before and after the task, each S completed a self-esteem measure. Differences between depressed and nondepressed, stabile and labile groups did not reach statistical significance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Thinking about a close relationship differentially impacts cardiovascular stress responses among depressed and nondepressed women.

Objective: Individuals with depression and low social support are at elevated risk for developing cardiovascular disease—presumptively through mechanisms involving dysregulated stress physiology. While depressed individuals often report diminished social support and elevated levels of social distress, few studies have examined how social factors impact stress-related cardiovascular activity in depressed samples. Accordingly, we evaluated the social modulation of stress-related cardiovascular activity in a sample of 38 medically healthy, unmedicated depressed and nondepressed individuals. Methods: Cardiovascular and psychological measures were obtained before and after depressed and nondepressed women engaged in a speech stress task. To evaluate the impact of social factors on stress responses, half of the women completed the speech stress task first, while the other half completed the speech stress after engaging in a relationship-focused imagery task. Results: Nondepressed women who first thought about a close relationship displayed global attenuations in blood pressure throughout the subsequent stress task, consistent with a stress-buffering effect of perceived social support. Conversely, depressed women who first thought about a close relationship displayed global elevations in blood pressure throughout the subsequent stress task, consistent with a stress-enhancing effect of perceived social distress in depressed women. Conclusion: Thinking about a close relationship differentially impacted subsequent cardiovascular activity during an evocative stressor in depressed and nondepressed women. Understanding the social context in which stress is experienced may aid in identifying, and ultimately attenuating, cardiovascular risks observed among patients with major depressive disorder.

Performance benefits of depression: Sequential decision making in a healthy sample and a clinically depressed sample.

Previous research reported conflicting results concerning the influence of depression on cognitive task performance. Whereas some studies reported that depression enhances performance, other studies reported negative or null effects. These discrepant findings appear to result from task variation, as well as the severity and treatment status of participant depression. To better understand these moderating factors, we study the performance of individuals—in a complex sequential decision task similar to the secretary problem—who are nondepressed, depressed, and recovering from a major depressive episode. We find that depressed individuals perform better than do nondepressed individuals. Formal modeling of participants' decision strategies suggested that acutely depressed participants had higher thresholds for accepting options and made better choices than either healthy participants or those recovering from depression.

Specificity and stability of self-referent encoding in clinical depression.

The self-referent encoding task was to investigate the specificity and stability of the self-schema in depression. Results of a comparison between depressed psychiatric (n?=?24), nondepressed psychiatric control (n?=?15), and nonpsychiatric control (n?=?14) patients revealed that the self-referent encoding task is specific to depression and that the use of content-specific adjectives in the task is important for the results obtained. A subset of the depressed group (n?=?9) who completed the task at a second occasion while still depressed showed results very similar to those obtained at the first testing occasion. A subset of depressed subjects (n?=?14) who completed the task on remission of their depression, however, evidenced a pattern of results quite dissimilar to those obtained while they were depressed. The pattern of results showed considerable shift in these subjects' self-referent encoding, and their results approximated those obtained by the two control groups. These results are discussed with reference to (a) the concept of the self-schema and its relevance for depression and (b) the self-referent encoding task as a means of assessing the self-schema.

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.
