Depression and causal attributions for success and failure

The present study investigated the effects of depression on causal attributions for success and failure. Specifically, female university students were separated into depressed and nondepressed groups on the basis of Costello--Comrey Depression Scale scores, and then received either 20%, 55%, or 80% reinforcement on a word association task. Following the task, attributions were made for outcome using the four factors of effort, ability, task difficulty, and luck. In accord with predictions generated from a self-serving biases hypothesis, nondepressives made internal (ability, effort) attributions for a successful outcome (80% reinforcement) and external attributions (luck, task difficulty) for a failure outcome (20% reinforcement). As predicted from consideration of the self-blame component of depression, the attributions made by depressives for a failure outcome were personal or internal. Contrary to expectations, depressives also made internal attributions for a successful outcome. The findings for depressives were discussed in relation to the recently revised learned helplessness model of depression, which incorporates causal attributions. For nondepressives, the findings were considered in terms of the self-serving biases hypothesis.     

Depression and preference for self-focusing stimuli after success and failure

Depressed individuals, who tend to have large perceived-self/ideal-self discrepancies, have been shown to be particularly high in private self-consciousness. On the bases of this finding and of several converging theoretical perspectives, we hypothesized that depressives, unlike nondepressives, do not find self-focus more aversive after failure than after success, and thus either (a) show no differential preference for self-focusing stimuli after success versus after failure (weak hypothesis), or (b) prefer self-focusing stimuli after failure over self-focusing stimuli after success (strong hypothesis). Depressed and nondepressed college students succeeded or failed on a supposed test of verbal intelligence, and then worked on two sets of puzzles, one in the presence and one in the absence of a self-focusing stimulus (mirror). Whereas nondepressed subjects liked the mirror-associated puzzle more after success than after failure, depressed subjects did not; depressed subjects tended to like the mirror-associated puzzle more after failure than after success. Nondepressed subjects also exhibited a self-serving pattern of attributions, viewing the test as less valid and luck as more responsible for their performance after failure than after success; depressed subjects showed no such differences. In consistency with their failure to use defensive strategies, depressed subjects showed a decrease in self-esteem after failure; nondepressed subjects showed no such change.     

The extent of Panum's area and the human cortical magnification factor

The horizontal extent of Panum's fusional area was measured by means of a single-vertical-line stimulus placed at thirty-two locations throughout the peripheral visual field. These results were transformed by using known values of the human cortical magnification factor (CMF), and the hypothesis that variations in the magnitude of Panum's area may be accounted for by variations in the CMF was tested. It was found that the increase in Panum's area with increasing stimulus eccentricity correlates well with the CMF, but that variations in the extent of Panum's area as a function of angular position around the line of sight do not correspond well with the CMF.     

Optical magnification as event information

Summary The geometrical optics of approach events is delineated. It is shown that optical magnification provides information about distance and time until collision. An experiment is described in which two objects - white styropor® spheres 10 cm in diameter, seen against a white plaster wall - were moved simultaneously at equal, constant speed along straight, converging paths at eye level towards a human observer and towards a common, virtual point of collision which either coincided with the observer's station point or was placed in front of, or behind, that point. Approach events differed with regard to trajectories, distances, velocities, and times-to-collision involved. Events were observed monocularly fixating and binocularly non-fixating, without head movements. The objects always stopped before colliding, and subjects had to respond to the virtual collisions. Most responses were too early, especially for impending collisions at, or behind the observers' station point. Responses for impending collisions in front of the observers tended to be too late, especially for larger total amounts of optical magnification and higher velocities, which together imply shorter times-to-collision. Relative errors were comparatively larger for very short and very long times-to-collision throughout, where events of the first kind were overshot, the latter ones undershot. Results are interpreted with reference to biological theories and the constraints imposed by geometrical optics. Special attention is focused on the issue of unavoidable, necessary confounding of variables in time-to-collision studies.     

Difficulties in the Treatment of Depression During Pregnancy and Postpartum Depression

Treatment with women who become depressed during pregnancy or who develop postpartum depression can be challenging. In certain cases where women have a poor parental representation rooted in a negative relationship with their own mothers, a powerful resistance emerges and can take the form of abandoning the treatment. For women who have a history of abandonment by one of the parents, this particular aspect of the relationship may be repeated. In others, where there is a great deal of anger towards the parent, in spite of conscious wishes to be different, there is an identification with this negative parental image; the new mother feels herself to be a bad mother and flees the treatment as a way to protect the baby. Biological as well as psychological factors present during pregnancy and postpartum depression, as well as the impact of the mother’s depression on the developing infant are described and clinical vignettes are provided to illustrate the main points.     

Depression and the soul

Clergy are often confronted by challenges in dealing with the depressed congregant. This paper addresses the interface between psychology, psychiatry, and religion in a discussion of two cases. Models are suggested for dealing with the issues raised by the depressed congregant. The paper developed from a symposium on “The Depressed Congregant: Three Pastoral Responses to a Case Vignette” presented at a conference for cleargy onDepression and The Soul, at Temple Sholom in Chicago.     

The effect of visual magnification and reduction on perceived hand size

The aim of the present study was to clarify the mechanisms underlying body understanding by examining the impact of visual experience (magnification and reduction) on perception of hand size and neutral external objects (squares). Independent groups of participants were asked to look through a 2× magnification lens, a ½-× reduction lens, or a control UV filter and to make visual size judgments about square stimuli and their hands. In Experiment 1, participants used a measuring device with unmarked wooden slats orientated in horizontal and radial/vertical space for their visual judgments. In Experiment 2, participants used an upright frontal slat for visual length judgments of their hands to eliminate any potential foreshortening in viewing the measurement apparatus. The results from the two experiments demonstrate that participants significantly underestimated both the square stimuli and their hands when they viewed them under a reduction lens. While overestimation and underestimation of squares was found for females in Experiment 2, males generally underestimated the squares. However, overestimation was not seen when the participants viewed their hands under a magnification lens. Implications of these findings are discussed.     

Age and individual differences in visuospatial processing speed: Testing the magnification hypothesis

Forty young adults and 40 older adults performed seven visuospatial information processing tasks. Factor analyses of the response times (RTs) yielded a single principal component with a similar composition in both age samples. For both samples, regressing the mean RTs of fast and slow subgroups for the seven tasks (18 conditions) on the corresponding mean RTs for their age group accounted for 99% of the variance. Taken together, these findings suggest that individual differences in processing time were largely task independent. The magnification hypothesis, a simple mathematical model of the interaction between age and ability, is presented. This model correctly predicts the finding that in both the young and the older adult groups, individual differences increased systematically with task difficulty. The magnification hypothesis also explains the regression parameters describing individual differences among young adults and predicts correctly that equivalent parameters describe individual differences among older adults. According to the magnification hypothesis, the RTs of slower individuals are more affected by aging than those of faster individuals, and slower individuals may be more at risk with respect to other biological insults (e.g., changes in health status) as well.     

Depression and the empty nest

The empty nest syndrome is a depressive reaction in middle-aged mothers attributed to role loss when all her children have grown up and left the nest. However, analyses of data from a large community mental health survey found that parents (both mothers and fathers) whose children were not living with them were significantly less depressed than other respondents of comparable age, income, occupational role, and marital status. This suggests that depression is not a typical reaction to an empty nest.     

Depression and the interpretation of ambiguity

A number of studies have produced findings consistent with the possibility that depressives display a negative bias in interpretation. However, the results of such studies can equally well be explained by the operation of a depression-linked response bias, reflecting an elevated tendency for depressives to emit or endorse negatively-toned response options. The present experiment compares the patterns of interpretative processing displayed by subjects who differ in their BDI scores, using a priming methodology developed by anxiety researchers to eliminate the contaminating influence of emotional response bias. The pattern of priming effects obtained provides no evidence to support the existence of a negative interpretative bias in the more depressive individuals. Indeed, quite the reverse conclusion is sustained by the findings, which indicate that high BDI subjects showed an attenuated tendency to activate the more negative interpretations of the ambiguous textual stimuli. The conceptual and methodological implications of these findings are discussed, together with some specific suggestions for future research on this topic.     

经验性回避对抑郁症发病的影响及慈心冥想干预方法的研究

经验性回避和反刍思维导致了抑郁症的发病和症状的持续,并且抑郁症的反刍思维与认知行为的回避倾向有非常密切的联系.以正念为基础的干预方法是当代心理学研究的一个热点,而与其密切相关的慈心冥想则很少被讨论.慈心冥想是指发展出对人的一种无条件、积极的慈爱与宽容的情感.正念能够增加对此时此刻的觉察,慈心冥想能够增加积极情感、降低消极情感,两者恰恰能够针对性地应对回避行为和反刍思维,从而减轻抑郁的症状.慈心冥想和正念冥想相结合,能为抑郁症提供更为有效的治疗.     

Boundary extension: the role of magnification, object size, context, and binocular information

Boundary extension is a tendency to remember close-up scenes as if they extended beyond the occluding boundaries. The authors explored the contributing factors using brief retention intervals and computer-generated images. Boundary extension turns out to be more complex than previously thought and is not linked to the effects of image magnification and field-of-view changes. Although this is consistent with the idea that boundary extension is the product of the activation of a mental schema that provides information of what is likely to exist outside the picture boundaries, the authors also found that properties of the object at the center of the picture can affect boundary extension independently of the information at the boundaries. In a test of boundary extension using stereograms, the effect does not seem to depend on amount of perceived depth, suggesting a weaker link to perception of space than previously hypothesized.     

Depression and Mortality in the Elderly

It is well known that depression can be a consequence of medical illness and disability, but a growing literature suggests also that depression can cause biological changes linked to morbidity and mortality. Depression is strongly implicated as a contributor to cardiovascular disease and mortality. Using the cascade-to-death model as a conceptual framework, we explore the complex relations among behavior, affect, motivation, and pathophysiology that might account for the association between depression and premature death. Our model suggests that some individuals become entrapped in a downward spiral in which behavior, medical illness, and depressive affect feed on each other to undermine the biological integrity of the organism. In addition to specifying behavioral and biological mechanisms linking depression to mortality, future research needs to more closely examine phenomenological aspects of depression in order to determine what aspects of depression and related constructs such ashopelessness, vital exhaustion, and motivational depletion account for the link between depression and mortality.
