The influence of personality on induced depressive mood

An experimental group (n = 40) of normal female undergraduates underwent a Velten type of depressive mood-induction procedure (DMIP) and was compared with a control group (n = 40) which underwent a neutral mood-induction procedure (NMIP). Ss were selected on the basis of scores on the EPI to give a composition in each group of 10 neurotic introverts (NI), 10 neurotic extraverts (NE), 10 stable introverts (SI) and 10 stable extraverts (SE). Depressive mood was assessed before and after each MIP using a measure of psychomotor retardation (writing speed). An ANOVA applied to residualized change scores on the writing-speed measure showed that the DMIP produced a significantly greater depressive effect on mood than the NMIP and that neurotic Ss displayed a significantly greater degree of depressive deficit than stable Ss regardless of type of MIP undertaken. However, a significant interaction between neuroticism and type of MIP showed that neurotic Ss were especially prone to depressive deficits in the DMIP. No effects of extraversion/introversion on susceptibility to depressed mood were detected. The results are discussed in terms of Eysenck and Gray's theory of personality predisposition to depression and it is suggested that the Velten technique may have limitations for the induction of depressed mood.     

Contrasting rule-based and similarity-based category learning: The effects of mood and prior knowledge on ambiguous categorization

This study adopts a dual-system view of category learning. The findings suggest that consumers who learn a dominant feature as a verbal rule for a product category will classify a new ambiguous product according to that feature even if it more closely resembles a different product category. The findings also demonstrate that dominant features can bias categorization toward a less prototypical category in the event that the new product breaks the rule. We refer to this phenomenon as criterial inferencing. Lastly, we offer unique empirical evidence to suggest that mood influences category learning and thus attenuates the criterial inferencing bias.     

Levels of processing in disruptive effects of prior information

Under certain conditions, advance information about possible letter alternatives may depress recognition of single tachistoscopically presented letters followed by a pattern mask. Neill and Walling (1981) found that this “before-disruption effect” occurred specifically when alternatives were featurally similar. In contrast, Experiment 1 of the present study found that precuing facilitated identification of unfamiliar stimuli composed of letterlike features, particularly when alternatives differed in only one critical feature. Contrary to Smith, Haviland, Reder, Brownell, and Adams (1976), composition of letterlike features is therefore not sufficient to produce the before-disruption effect. The before-disruption effect appears to occur when there is opportunity to represent the stimulus at a deeper (i.e., name) level, but foreknowledge of a critical distinguishing feature biases processing instead toward the level of physical features. Congruent with this analysis, Experiment 2 found the before-disruption effect for letters to be attenuated when targets were unpredictably upper- and lowercase, necessitating name-level matching to the alternatives. Experiment 3 found the superior identification of unprecued letters to be paradoxically associated with inferior target detection, as indicated by concurrent presence/absence judgments. In addition, identification of unprecued letters, but not precued letters, was significantly above chance on trials in which overt target detection failed to occur. The results are consistent with recent suggestions that pattern masking does not terminate perceptual processing, but rather interferes with conscious awareness of completed visual analysis.     

The effects of attention retraining on depressive mood and cortisol responses to depression‐related stimuli1

Although it has been reported that attentional bias at an early stage is found in depression, no study has investigated the effects of modification of attentional bias at an early stage on depressive mood and cortisol response to a stressor. Therefore, this study tested the hypotheses that the modification of attentional bias at an early stage would reduce depressive mood and cortisol response. Fifty‐three participants were allocated alternately either to the training or the control group. They were administered attention retraining for modification of attentional bias or a sham attention task, and then underwent a stress task. With respect to depressive mood response, depressive mood increased in response to a stress task in the control group, while for high‐dysphoric participants in the training group, depressive mood response remained constant. These results indicate that attention retraining is efficacious for reducing depressive mood response. With respect to cortisol response, the percentage change in cortisol is associated with the amount of change in the attentional bias index scores. The results suggest the possibility that attention retraining could reduce cortisol response.     

Negative mood,depressive symptoms,and major depression after smoking cessation treatment in smokers with a history of major depressive disorder

Negative mood, depressive symptoms, and major depressive episodes (MDEs) were examined in 179 smokers with a history of major depression in a trial comparing standard smoking cessation treatment to treatment incorporating cognitive-behavioral therapy for depression (CBT-D). Early lapses were associated with relatively large increases in negative mood on quit date. Mood improved in the 2 weeks after quit date among those returning to regular smoking but not among those smoking moderately. Continuous abstinence was associated with short- and long-term reductions in depressive symptoms. MDE incidence during follow-up was 15.3% and was not associated with abstinence. Unexpected was that CBT-D was associated with greater negative mood and depressive symptoms and increased MDE risk. Results suggest complex bidirectional associations between affect and smoking outcomes.     

Sad-and-social is not smart: The moderating effects of social anticipation on mood and information processing

We examined if anticipating working collectively, rather than individually, moderates the effects of mood on information processing through (a) distraction, (b) loafing, and/or (c) task engagement. When participants anticipated working collectively, rather than individually, those in sad moods became distracted by the social elements of the task, resulting in a reduced information focus. In contrast, those in happy moods became engaged in the collective task, increasing their intended effort, raising their information focus, and improving their performance on the task. Social loafing effects did not occur. Mediation analyses revealed that these effects were due to changes in information focus, not social focus or intended effort.     

The effects of unemployment on the mood,self-esteem,locus of control,and depressive affect of school-leavers

The purpose of this study was to investigate some psychological effects of unemployment in school-leavers using a longitudinal research design. Questionnaires which included mood questions and scales measuring self-esteem, locus of control and depressive affect, were administered twice to 761 students, once while they were at school, and then again one year later. Comparisons between the unemployed and employed groups revealed that the unemployed were generally less well-adjusted than their employed counterparts. Specifically they reported greater negative mood and had higher depression scores, and the unemployed girls also displayed lower self-esteem. These differences, however, resulted largely from an improvement in outlook on the part of the employed, rather than from the unemployed becoming more depressed and losing self-esteem.     

Social-cognitive processing and depressive symptoms in children: A comparison of measures

We assessed aspects of the reliability and validity of three measures of socialcognitive processing in children that have been developed to investigate the relations of such processes to childhood depression: the Children's Attributional Style Questionnaire (CASQ), the Children's Negative Cognitive Error Questionnaire (CNCEQ), and the Common Beliefs Inventory for Students (CBIS). In an unselected sample of 61 children, aged 8 to 12, the internal consistencies of the total scores on the CNCEQ and the CBIS were good; for the CASQ, it was only moderate. Internal consistencies of all subscale scores were inadequate. Despite this, several subscale and total scores were significantly associated with depressive symptoms, and the measures were generally correlated with each other. Although these data are encouraging concerning the role of social-cognitive processing in childhood depression, the field needs to develop psychometrically stronger measures and to test the role of social cognition in prospective studies of depression.This study was supported in part by a grant from the Spencer Foundation Awards to Young Scholars Program to the first author.

Feeling good and feeling truth: The interactive effects of mood and processing fluency on truth judgments

Can mood states influence the perceived truth of ambiguous or novel information? This study predicted and found that mood can significantly influence people’s reliance on processing fluency when making truth judgments. Fluent information was more likely to be judged as true (the truth effect), and consistent with Bless and Fiedler's (2006) assimilative vs. accommodative processing model, negative mood eliminated, and positive mood maintained people's reliance on processing fluency as an indication of truth. Post hoc analyses confirmed the predicted mood-induced differences in processing style, as judges in a negative mood adopted more accommodative processing and paid greater attention to external stimulus information. The relevance of these results to contemporary affect-cognition theories is discussed, and the real-life implications of mood effects on truth judgments in applied areas are considered.     

The influence of prior choices on current choice

Three pigeons chose between random-interval (RI) and tandem, continuous-reinforcement, fixed-interval (crf-FI) reinforcement schedules by pecking either of two keys. As long as a pigeon pecked on the RI key, both keys remained available. If a pigeon pecked on the crf-FI key, then the RI key became unavailable and the crf-FI timer began to time out. With this procedure, once the RI key was initially pecked, the prospective value of both alternatives remained constant regardless of time spent pecking on the RI key without reinforcement (RI waiting time). Despite this constancy, the rate at which pigeons switched from the RI to the crf-FI decreased sharply as RI waiting time increased. That is, prior choices influenced current choice-an exercise effect. It is argued that such influence (independent of reinforcement contingencies) may serve as a sunk-cost commitment device in self-control situations. In a second experiment, extinction was programmed if RI waiting time exceeded a certain value. Rate of switching to the crf-FI first decreased and then increased as the extinction point approached, showing sensitivity to both prior choices and reinforcement contingencies. In a third experiment, crf-FI availability was limited to a brief window during the RI waiting time. When constrained in this way, switching occurred at a high rate regardless of when, during the RI waiting time, the crf-FI became available.     

Psychometric detection of depressive mood conditions

An investigation into the diagnostic value of psychometric methods for the diagnosis of depressive states involved five psychometric questionnaires, one concentration test procedure, and one problem-solving approach to register cognitive processes. The data obtained for 80 depressive patients of varied aetiology were compared with those of sample of 80 neurotics without depressive aberration. Even univariate comparisons revealed statistically significant differences between the two samples. Multivariate methods (factor analysis, discriminative analysis) yielded more differentiated information. The "Scale for depression depth measurements" was found to be of particular diagnostic relevance; it was standardized for the time being.     

The effects of storage and processing complexity on comprehension repair in children and adults

In four experiments, the ability of young children (6 to 10 years of age) and college adults to repair a comprehension problem in situations varying repair difficulty was examined. The subjects were read short stories describing a consistent or inconsistent adult response to a child's action, and repair information that resolved or failed to resolve the inconsistency. The subjects were asked questions after each story to determine if they had detected and resolved the inconsistency. The repair information was manipulated as a means of varying the storage and prosessing complexity of integrating problem and repair information. The information was separated from or adjacent to the inconsistent response, before or after the response, and the relevancy of the repair information was obvious or only inferentially available. The results showed that even first graders can repair a comprehension problem in situations of minimal information processing complexity, and that increments in complexity affect the repair performance of younger more than older subjects.     

Diurnal mood variation in major depressive disorder

Depression disturbs mood, but a clear picture of diurnal mood rhythms in depression has yet to emerge. This study examined variations in positive affect (PA) and negative affect (NA), two dimensions of mood that generate diurnal patterns among healthy individuals. Repeated measurements of NA and PA in daily life were obtained over 6 days from 47 depressed outpatients and 39 healthy individuals using the Experience Sampling Method. Relative to healthy individuals, depressed individuals exhibited increasing PA levels during the day with a later acrophase. In contrast, depressed persons' NA exhibited a more pronounced diurnal rhythm and was more variable from moment to moment than healthy individuals'. Ambulatory mood measurements in depression suggest distinct diurnal disturbances of positive and negative affect.     

Selective effects of prior motivational experience on current on-line control of attention

This study examined the influence of prior motivational experience on the efficiency of executive attention control during performance of a task set reconfiguration task (Rogers & Monsell, 1995). Results revealed that motivation manipulations selectively affected attention switching mechanisms, but did not influence either inhibition of crosstalk from competing stimuli, or basic response execution time. This provides additional evidence for distinct attentional systems involved in resolution of response and perceptual competition. Speculations regarding the neural systems that mediate both motivation and attention switching are considered, pointing to a possible involvement of dopaminergic influences on the ventral striatum.     

Adaptive social reasoning in depressed mood and depressive vulnerability

In this study we evaluate the evolutionary hypothesis that depressed states are associated with more adaptive reasoning about social risks, such as defeat or rejection. A total of 78 women were administered one of two mood inductions (depressed vs. neutral), followed by four Wason selection reasoning tasks (truth-detection, cheater-detection, and two social risk tasks addressing attachment and social competition risks). Those in the depressed mood condition gave significantly more correct responses on a task requiring participants to reason about social competition. There were no significant differences on performance for the other reasoning tasks between the two mood induction conditions. Furthermore, measures of two dimensions of depression prone personality (sociotropy and autonomy) were associated with less adaptive reasoning about social risks. These results suggest that mildly depressed states may indeed facilitate adaptive reasoning within certain domains, whereas vulnerability to depression may be associated with a relative impairment in reasoning about social risks.     

Effects of daily events on mood states in major depressive disorder

Major depressive disorder (MDD) is characterized by high negative affect (NA) and low positive affect (PA), but little is known about emotional reactivity in daily life. The authors used experience sampling methodology to investigate changes in NA and PA following minor daily events in MDD compared with healthy participants. Contrary to expectation, MDD participants did not report more frequent negative events, although they did report fewer positive events. Multilevel regression showed that both NA and PA responses to negative events were blunted in the MDD group, whereas responses to positive events were enhanced. NA responses to negative events persisted longer in MDD participants. Depressed participants with a positive family history or longer current episodes showed relatively greater NA responses to negative events.     

The effects of maternal mood on mother-infant interaction

The effects of depressed mood on mother-infant interaction were studied in 30 mother-infant dyads using the Velten mood induction procedure. It was predicted that maternal depressed mood would induce dysphoria in the infants, disrupt the infants' natural responsiveness to their mothers, and interfere with the mothers' ability to manage the interaction. In addition, it was predicted that such deficits would be the result of depressed maternal mood and not simply due to any change in maternal mood. The results indicated that the infants were sensitive to depressed mood and were less contingently responsive to their mothers than were controls. Also, mothers in the depression induction condition were less successful in eliciting positive responses from their infants than were controls. These results have implications for the development of a helplessness vulnerability in infants and for the two-way direction of effect present in depressed mother-infant dyads.This research was partially funded by NIMH grant MH39283 and a Spelman-Rockefeller Seed Grant awarded to Michael O'Hara.

Understanding the impact of prior depression on stress generation: Examining the roles of current depressive symptoms and interpersonal behaviours

Stress generation is a process in which individuals contribute to stressful life events. While research has supported an association between current depression and stress generation, it has been noted that individuals with prior depression tend to contribute to stressors even when they are no longer experiencing a depressive episode. The aim of the study is to elucidate the pathways through which prior major depression predicts interpersonal stress generation in women. Specifically, we examined current subsyndromal depressive symptoms and problematic interpersonal behaviours as potential mediators. Fifty‐one college women were followed prospectively for 6 weeks. Participants were interviewed to assess current and past depression as well as stressful life events they experienced over the 6‐week period. The findings suggest that prior major depression continues to have an impact even after the episode has ended, as the disorder continues to contribute to stress generation through residual depressive symptoms.     

The depressive personality disorder inventory and current depressive symptoms: implications for the assessment of depressive personality

The Depressive Personality Disorder Inventory (DPDI; Huprich, Margrett, Barthelemy, & Fine, 1996; see Appendix) was created to assess Depressive Personality Disorder in clinical and nonclinical samples. Since its creation, the DPDI has been used in multiple studies, and the psychometric properties of the measure have generally supported its reliability, convergent validity, and construct validity; however, evidence for the measure's discriminant validity has been mixed. Specifically, the DPDI tends to correlate highly with measures of current depressive symptoms, which limits its efficacy in differentiating current depressive symptoms from a depressive personality structure. A principal components analysis of 362 individuals who completed both the DPDI and Beck Depression Inventory (BDI-II; Beck, Steer, & Brown, 1996) found that 49% of the variance was accounted for in two components. Seven items from the DPDI loaded more strongly on the first component composed of many BDI-II items. These items were removed in order to create a measure believed to assess DPD without the confounding influence of current depressive symptomology. Principal components analysis of the revised measure yielded three components, accounting for 46% of the variance. The revised DPDI was used to calculate convergent, discriminant, and construct validity coefficients from measures used in former studies. Virtually no improvement in the validity coefficients was observed. It is concluded that assessing DPD via self-report is limited in its utility.
