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.     

Seeing the big picture: Broadening attention relieves sadness and depressed mood

We examined whether the broadened attentional scope would affect people's sad or depressed mood with two experiments, enlightened by the meaning of “seeing the big picture” and the broaden‐and‐build model. Experiment 1 (n = 164) is a laboratory‐based experiment, in which we manipulated the attentional scope by showing participants zoomed‐out or zoomed‐in scenes. In Experiment 2 (n = 44), we studied how depressed mood and positive and negative emotions were affected when participants watched distant versus proximal scenes for eight weeks in real life. Healthy participants in Experiment 1, who were induced to feel sad, could return to the baseline mood after having the broadened attention task but not after having the narrowed attention task, which indicated that immediate attention broadening manipulation could function as antidotes for the lingering effects of induced negative emotions. Participants with depressed mood in Experiment 2 showed reduced depressed mood, increased positive affect, and decreased negative affect after receiving attention broadening training compared to those receiving attention narrowing training. Our findings suggest a robust role of broadened attentional scope in relieving negative emotions and even mildly depressed mood in the long run.     

The influence of mood on perceptions of social interactions

Interpreting our own and others' social behaviors is an important cognitive task in everyday life. Recent work in cognitive psychology suggests that temporary mood states may have a significant effect on the way information about common social events is processed. This study investigated how (a) a person's current mood, (b) the target of the judgments (self vs other), and (c) the characteristics of the social episode (formal-informal; intimate-nonintimate) influenced people's assessment of, and memory for, social behaviors. Subjects were videotaped while engaging in four different kinds of interactions with trained confederates. One day later subjects were hypnotized, and a happy, positive, or depressed, negative mood was induced. They then watched and rated their own and their partner's interactions on the videotape. Results showed strong mood influence on behavior assessments and recall memory, and significant effects due to target (self vs other) and the type of interaction episode. These results are discussed in terms of their implications for contemporary research on social cognition, and their relevance to cognitively based theories of social maladjustment and depression are considered.     

Vulnerability to depression: cognitive reactivity and parental bonding in high-risk individuals

Although various conceptual proposals have suggested that disruptions in childhood bonding processes may be linked to the origins of these cognitive structures, little research has tested these proposals. This study assessed the information processing of vulnerable individuals and its relationship to childhood bonding. Formerly depressed (vulnerable) and never depressed (nonvulnerable) individuals participated in a mood induction task followed by an attentional allocation task. Results indicated that vulnerable individuals uniquely diverted attention toward negative stimuli when they were in a negative mood. Furthermore, level of maternal caring was found to be associated with performance on this task for vulnerable individuals in this mood state. These data support the idea that cognitive variables form a pathway between troublesome parental-child/adolescent interactions and depression.     

Affect and persuasion: Mood effects on the processing of message content and context cues and on subsequent behaviour

Two experiments are reported examining the impact of recipients' mood on the processing of simple, everyday persuasive communications and on subsequent behaviour. Consistent with the general assumption that affective states may inform an individual about the state of its current environment, it was found that positive (as compared to neutral or negative) mood reduced subjects' motivation to systematically process both content information and contextual cues. Specifically, Experiment I demonstrated that, in a field setting, the behaviour of subjects who had been put in a good mood was less likely to reflect differences in message content than the behaviour of neutral mood subjects. Experiment 2 replicated and extended these findings, showing that good mood subjects' behaviour was uninfluenced by content as well as context information, whereas bad mood subjects did make use of both types of information. Subject's cognitive responses and evaluations paralleled the behavioural data. The results are discussed in terms of their compatibility with contemporary models of persuasion, and their implications for future research on mood and persuasion and on the interplay of affect and cognition in general are considered.     

Neuroticism and the recall of positive and negative personality information

Recent investigations have shown that high-N scorers preferentially process negative information about themselves. The present experiment investigated: (1) whether this effect is related to, or independent of, the well-established effects of depressed mood on information processing; (2) whether the effect is specific to self-referent information or extends also to information about others; and (3) the mechanism by which the effect occurs. High-N scorers, compared to low-N scorers, recalled more negative information about themselves but not about others, and this effect was independent of depression. In addition, the positive self-referent, but not other-referent, personality information recalled by high-N scorers was more extremely positive than that recalled by low-N scorers. Detailed examination of the data provided evidence that the idiosyncracy in information processing associated with high neuroticism is one of selective attention. The findings are discussed in relation to cognitive vulnerability to depression, certain cognitive-therapy procedures and the effects that a therapeutically-induced change in neuroticism is likely to have on an individual's memory for past emotional experiences.     

Intrusive images and memories in major depression

Individuals with current major depression were interviewed to investigate the prevalence of distressing intrusive mental imagery among depressed patients and study the phenomenology of these intrusions. Of the 39 currently depressed patients, 17 experienced some form of repetitive intrusive imagery (i.e., either an intrusive memory or image), with intrusive memories being more common than images. The intrusive imagery was experienced as highly uncontrollable and interfered significantly with patients' everyday lives. The intrusions were experienced with a sense of 'nowness', as well as physical and emotional re-experiencing. Despite high levels of re-experiencing, levels of dissociation were very low. The intrusive imagery was in some patients part of a wider network of key defining autobiographical memories, consistent with the idea that it is likely to play a significant role in maintaining the patient's depressive mood. Interventions targeting these intrusions could potentially result in a positive shift in depressed mood.     

Emotion and prior knowledge in memory and judged comprehension of ambiguous stories

Abstract

Two experiments investigated the effects of experimentally induced mood states on memory and judged comprehension of stories. The experiments examined the issue of whether induction of a depressed mood would affect prose memory and comprehension and impair the ability of individuals to use prior knowledge, activated by way of a title, in remembering the passage. In Experiment 1, depressed subjects who were given a title for the passage recalled fewer idea units when compared with neutral control conditions, but no depressive deficit in recall occurred in the absence of a title. In Experiment 2 the same pattern of results occurred when subjects learned two successive passages. The depressive deficits obtained were interpreted in terms of a resource allocation model which proposes that emotional states increase the production of irrelevant, competing thoughts that interfere with processes important in remembering the criterion passage. Alternative explanations involving cognitive initiative and schema theory were discussed. Finally, judgments of comprehension predicted passage recall and were better predictors for neutral than depressed mood subjects. A depressed mood state did not affect average judgments of comprehension even when recall was correspondingly impaired.     

Mood and the generation effect

Three experiments address the assumptions, derived from a dual-force model, that positive mood supports assimilative (knowledge-driven) processes whereas negative mood supports accommodative (stimulus-driven) functions, and that mood-selective recall (mood congruency) is mainly a matter of assimilation. The generation-effect paradigm was borrowed from memory research to test these assumptions. In Experiment 1, the theoretical variable, degree of assimilation, was operationalised by the ease with which stimulus meaning could be generated from word fragments. In Experiment 2, self-generated stimuli (assimilation) were compared to experimenter-provided stimuli (accommodation). As predicted, positive mood supported assimilation which in turn enhanced mood-congruent recall. In Experiment 3, retrieval mood rather than encoding mood was manipulated. In this situation, positive mood facilitated the recall of all self-generated information, whether congruent or not. The empirical results are generally consistent with the predictions derived from the dual-force framework.     

The influence of induced mood on the inhibition of emotional information

The ability to inhibit affective information plays a major role in efficient cognitive processing. In this study the effect of mood induction on inhibitory processing of emotional material was investigated. In Experiment 1, performance on a negative affective priming task (NAP) following negative and positive mood induction (MIP) was compared to a neutral mood condition. Results revealed that, as compared with the neutral mood condition, inhibitory function for affective material was unaffected by negative MIP. However, after the positive MIP, inhibitory processes were significantly impaired. In Experiment 2, we replicated and extended the findings on positive affect and inhibition. The data concerning positive mood fit with the general findings that positive mood often leads to a “loose, flexible” processing mode. The null-finding concerning negative mood and inhibition is discussed in the light of research on inhibition in depression.     

Happiness increases verbal and spatial working memory capacity where sadness does not: Emotion,working memory and executive control

The effects of emotion on working memory and executive control are often studied in isolation. Positive mood enhances verbal and impairs spatial working memory, whereas negative mood enhances spatial and impairs verbal working memory. Moreover, positive mood enhances executive control, whereas negative mood has little influence. We examined how emotion influences verbal and spatial working memory capacity, which requires executive control to coordinate between holding information in working memory and completing a secondary task. We predicted that positive mood would improve both verbal and spatial working memory capacity because of its influence on executive control. Positive, negative and neutral moods were induced followed by completing a verbal (Experiment 1) or spatial (Experiment 2) working memory operation span task to assess working memory capacity. Positive mood enhanced working memory capacity irrespective of the working memory domain, whereas negative mood had no influence on performance. Thus, positive mood was more successful holding information in working memory while processing task-irrelevant information, suggesting that the influence mood has on executive control supersedes the independent effects mood has on domain-specific working memory.     

Effect of thought-stopping on thoughts,mood and corrugator EMG in depressed patients

The immediate effects of thought-stopping applied to depressive thoughts were compared to those of a control procedure in a group of depressed psychiatric day-patients. Thought-stopping had only a weak effect on average in reducing the frequency of depressive thoughts, and no significant effects on depressed mood or corrugator EMG. A small significant effect on anxious mood appeared related to non-specific factors. The results raise the possibility that thought-stopping may have little specific effect in reducing the frequency of unwanted thoughts. Corrugator EMG was significantly related to the frequency of spontaneously occurring depressive thoughts both between and within subjects.     

Persistent high self-focus after failure and low self-focus after success: the depressive self-focusing style

Two studies were conducted to assess the spontaneous self-focusing tendencies of depressed and nondepressed individuals after success and failure. Based on a self-regulatory perseveration theory of depression, it was expected that depressed individuals would be especially high in self-focus after failure and low in self-focus after success. The results of Experiment 1 suggested that immediately after an outcome, both depressed and nondepressed individuals are more self-focused after failure than after success. This finding led us to hypothesize that differences between depressed and nondepressed individuals in self-focus following success and failure emerge over time. Specifically, immediately following an outcome, both types of individuals self-focus more after failure because of self-regulatory concerns. However, over time, depressed individuals persist in higher levels of self-focus after failure than after success, whereas nondepressed individuals shift to the opposite, more hedonically beneficial pattern. The results of Experiment 2 provided clear support for these hypotheses. Theoretical implications of these results were discussed.     

Affective influences on partner choice: role of mood in social decisions.

Does mood influence our information search and decision strategies when choosing a partner? In Experiment 1 (N = 60), sad Ss preferred rewarding to competent partners and remembered information supporting that choice better. In Experiment 2 (N = 96), mood effects on information selectivity, decision speed, and processing strategy in partner choices were found. In Experiment 3 (N = 42), a computerized stimulus presentation revealed mood-induced differences in the latency, self-exposure, and eventual recall of interpersonal information. These results are interpreted as evidence for mood-induced selectivity in information search and decision strategies when making realistic partner choices. The implications of the findings for research on interpersonal relations and for contemporary affect-cognition theories are considered.     

Depression,restraint and eating behavior

Contrary to the belief that weight loss is a principal symptom of depression, several recent studies have suggested that certain people gain rather than lose weight when depressed. The present experiment concerned the effects of experimentally induced mood states on the eating behavior of high- and low-restraint persons. Sixty-eight female undergraduates were randomly assigned to one of three groups each designed to induce a different mood state (depressed, neutral or elated), and were classified as high or low restraint based on their responses to a questionnaire. During the mood induction procedure subjects were provided with the opportunity to eat. High-restraint persons induced into a depressed mood ate significantly more than high-restraint persons induced into neutral or elated moods, and more than low-restraint persons induced into a depressed mood. This effect was most prominent among subjects who scored high on the weight-fluctuation factor of the restraint scale. There was no evidence that this effect occurred among subjects who scored high on the concern for dieting factor. The role of emotional arousal on the self-control over eating behavior of high weight-fluctuation persons, and the implications of these findings for the evaluation of depression were discussed.     

特质性与情境性调节定向匹配效应的一致性

研究试图探讨基于不同性质的调节定向(特质性调节定向和情境性调节定向)而达成的匹配所导致的效应是否一致。实验一、二均采用2(调节定向：促进、防御)×2(信息框架：积极、消极)被试间设计, 分别考察了两种匹配对信息说服效果(包括信息价值评价、情绪强度、行为意向3项指标)的影响。MANOVA检验表明, 实验一中信息价值评价、情绪强度2项指标上的交互作用显著, 实验二中信息价值评价、情绪强度和行为意向3项指标上的交互作用显著; 这表明, 基于两种不同性质的调节定向所达成的匹配在对信息价值评价和情绪强度的影响上具有一致的效应, 但在对行为意向的影响上具有不一致的效应。这一结果对于理解两种不同性质的调节定向之间的差异以及基于两者而达成的两种调节匹配之间的差异具有较为重要的意义。     

Reduced specificity of autobiographical memory and depression: the role of executive control

It has been widely established that depressed mood states and clinical depression, as well as a range of other psychiatric disorders, are associated with a relative difficulty in accessing specific autobiographical information in response to emotion-related cue words on an Autobiographical Memory Test (AMT; J. M. G. Williams & K. Broadbent, 1986). In 8 studies the authors examined the extent to which this relationship is a function of impaired executive control associated with these mood states and clinical disorders. Studies 1-4 demonstrated that performance on the AMT is associated with performance on measures of executive control, independent of depressed mood. Furthermore, Study 1 showed that executive control (as measured by verbal fluency) mediated the relationship between both depressed mood and a clinical diagnosis of eating disorder and AMT performance. Using a stratified sample in Study 5, the authors confirmed the positive association between depressed mood and impaired performance on the AMT. Studies 6-8 involved experimental manipulations of the parameters of the AMT designed to further indicate that reduced executive control is to a significant extent driving the relationship between depressed mood and AMT performance. The potential role of executive control in accounting for other aspects of the AMT literature is discussed.     

Effects of positive mood on attention broadening for self-related information

Studies on cognitive effects of positive emotions have associated positive emotions to broadened attention. Given the widely investigated relationship between self-focused attention and mood, it is important to investigate the effect of positive mood on visuospatial attention for self-related information. We used a performance-based measure to assess fluctuations in attentional broadening from self-related contrasted to not-self-related information. In Experiment 1, we checked that the self-related versus not-self-related stimuli did not evoke differential attention effects in general. In Experiment 2, we manipulated mood and found that an increase in positive mood was associated with a relative broadening of attention for self-related information. These results suggest that the meaning of the target of attention provides an interesting dimension for further investigation into the relation between positive emotions and attentional broadening.     

A hidden cost of happiness in children

Happiness is generally considered an emotion with only beneficial effects, particularly in childhood. However, there are some situations where the style of information processing triggered by happiness could be a liability. In particular, happiness seems to motivate a top-down processing style, which could impair performance when attention to detail is required. Indeed, in Experiment 1, 10- to 11-year-old children (N = 30) induced to feel a happy mood were slower to locate a simple shape embedded in a complex figure than those induced to feel a sad mood. In Experiment 2, 6- to 7-year-old children (N = 61) induced to feel a happy mood found fewer embedded shapes than those induced to feel a sad or neutral mood. Happiness may have unintended and possibly undesirable cognitive consequences, even in childhood.
