Effect of depression on quantity and quality of social inferences

Two studies explored depressives' sensitivity to social information as an impediment to their gaining a sense of confidence and control. In Study 1, Ss viewed a videotape of an actor performing an achievement task and were asked to list their impressions of the actor. As compared with nondepressed Ss, depressed Ss generated more inferences overall, generated more abstract inferences, and exhibited less overall confidence in their impression of the actor. In Study 2, Ss reported their beliefs of the utility of information about a person's past behaviors and personality for understanding, predicting future behavior, and describing that person. Depressed Ss expressed more interest than did nondepressed Ss in both types of information but were less confident of the utility of the information for prediction.     

Influence of mood on health-relevant cognitions

Three experiments assessed the effects of mood on symptom appraisal, health behavior self-efficacy, outcome expectations, and perceptions of vulnerability. Ss in Experiments 1 and 2 were acutely ill, whereas Ss in Experiment 3 were healthy. In each experiment, happy, sad, and neutral moods were induced. In Experiment 1, Ss who experienced sadness reported more aches and pains and greater discomfort than happy Ss. Sad Ss were less confident that they could carry out illness-alleviating behaviors. Experiments 2 and 3 demonstrated that mood's influence on vulnerability perceptions is moderated by health status. Although mood had little impact on perceptions of vulnerability among ill Ss, probability estimates of future negative health-relevant events among healthy Ss were mood sensitive. Seeing oneself as invulnerable to future negative events was accentuated among happy Ss and attenuated among sad Ss. Mood may be an important determinant of care seeking, adherence, and recovery from illness.     

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 two 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.     

The effects of stimulus structure and familiarity on same-different comparison

It was hypothesized that performance in the same-different comparison task is based on two modes of processing: (1) structural processes that organize the detailed parts of a stimulus into a well-formed whole, and (2)analytic processes that decompose the stimulus into features. This hypothesis was supported, but with the unexpected finding of individual differences in the mode of processing underlying “same” responses. Those Ss in the “same” condition whose reaction times were faster for symmetrical than for asymmetrical patterns supported the hypothesis for structural processes. The remaining Ss in the “same” condition, as well as all the Ss in the “different” condition, were unaffected by symmetry. These Ss supported the hypothesis for analytic processes. Although familiarity effects were obtained for both structural and analytic Ss, the rotation of the familiar patterns into an unfamiliar orientation virtually eliminated familiarity effects for the structural Ss, but left them intact for analytic Ss.     

A Test of the Adams-Creamer Decay Hypothesis for the Timing of Motor Responses

The Adams-Creamer hypothesis states that S uses the decay of proprioceptive feedback from an early portion of a movement to cue a timed response at some later time. This hypothesis was tested by creating passive left-arm movement in one group and withholding it from another, and having Ss make a right-hand response when exactly 2.0 sec. had elapsed since the end of the movement Ss with left-arm feedback had less absolute and algebraic error, and greater within-S consistency than did the no-movement control Ss and, when KR was withdrawn, Ss with left-arm movement regressed less than did Ss without the left-arm movement, which provided 2 lines of support for the decay hypothesis.     

Relationship between pulse pressure, arteriosclerosis, and a visual reversal phenomenon.

Varying numbers of Ss were studied on a task producing a perceived reversal in the direction of rotating objects. Ss were required to indicate when reversal in the direction of rotation of the percept occurred for the first time. Low initial reversal time coincided with high pulse pressure which is an indicator or arteriosclerotic processes. The relationship of initial reversal time and pulse pressure existed for all Ss with histories of cerebro-vascular accident, amputees secondary to diabetes mellitus, and many control Ss (a nonpatient group of higher socio-economic and intellectual levels) who had a poor health history regarding high blood pressure and/or diabetes mellitus. In contrast, control Ss with no cardio-vascular or diabetic problems had high initial reversal times or no reversal at all. Initial reversal time was stable over a short as well as longer periods of time. Initial reversal time may be useful as an adjunct in the prognosis of arteriosclerotic pathology.     

Are shy people reluctant to ask for help?

Examined the help-seeking behaviors of shy and not-shy men and women. In Study 1, Ss worked on an impossible task in the presence of a male or female confederate whom they were told had just successfully completed the task. Shy Ss asked for help no less frequently than did not-shy Ss overall, but they did seek help less frequently from opposite-sex confederates than from same-sex confederates. In Study 2, shy and not-shy men and women were required to call a man and a woman and ask them to complete a questionnaire. All respondents agreed to return the questionnaire. However, when shy Ss (compared with not-shy Ss) called opposite-sex respondents, fewer of the questionnaires were actually returned. When making their calls, shy Ss sounded somewhat less warm and confident than did not-shy Ss, and they also spoke less fluently. Fluency, in turn, predicted response rate for the shy subjects calling respondents of the opposite sex.     

Contextual relations: The influence of familiarity,physical plausibility,and belongingness

Individual differences were obtained in a task requiring the same-different comparison of multiobject scenes. For some Ss, performance depended only on whether the objects were in a physically plausible arrangement. It was inferred that these Ss used internalized rule systems to interrelate arrays of objects into organized scenes. For the other Ss, performance depended on whether the objects belonged together, and whether their arrangement was familiar. It was inferred that these Ss dealt with each object on an individual basis, using information concerning belongingness and familiarity of arrangement to anticipate which objects would be present and where they would be located.     

Temporal Orientation,Human Movement Responses and Time Estimation

The relationship between temporal orientation, human movement (M) responses on the Barron inkblots, and brief time estimates was investigated. Knapp's Time Metaphor Test and the Barron inkblots were administered to 110 Ss. 40 Ss were selected on the basis of their scores on the Time Metaphor Test to participate in an individual time estimation experiment This produced two criterion groups: 20 Dynamic-Hasty (D-H) Ss and 20 Naturalist-Passive (N-P) Ss. Results indicated that N-P Ss had a lower M threshold, perceived more M and overestimated the passage of time. Discussion focused on the relationship between temporal orientation, fantasy behavior, and impulse control.     

Improving recall by recoding interfering material at the time of retrieval.

Our experiments demonstrate that interference of an interpolated list of items with recall of an original list can be substantially reduced by forming Ss just before testing how to reorganize and simplify the interpolated material. In Experiments 1 and 2, Ss better recalled an initial serial list of letters when informed at testing that an interpolated list spelled a certain phrase backward. Similarly, in Experiments 3 and 4, Ss better recalled an initial list of cities when told that the interpolated cities were also names of former U.S. presidents. Control experiments rule out several simple explanations. In contrast to an editing hypothesis, the postorganizing clue helped recall even when problems of list differentiation were minimized. Current memory models appear unable to explain this benefit of a postlearning clue that enables Ss to segregate the interpolated material from the to-be-remembered material.     

Operant GSR conditioning with cool air reinforcement

Two groups of 20 Ss each were run individually in a soundproof chamber heated to 115 F and humidified to 100%. Ss in the experimental group received brief presentation of cool air contingent upon emitted GSRs during 20 min of acquisition. Control Ss were matched one at a time in operant rate and were yoked one at a time to receive the cool air on a response-independent schedule. Both groups increased significantly in rate of unelicited GSRs during acquisition, with the experimental Ss’ curve rising more rapidly and both groups attaining equivalent terminal levels. During extinction, the groups maintained high levels of responding and did not differ. Examination of basal skin conductance data ruled out an activation hypothesis. In the control Ss, terminal response frequency was significantly correlated with percentage of fortuitous response-contingent reinforcement. It was concluded that both groups were conditioned, with the controls receiving intermittent reinforcement sufficiently often to elevate their responding. The cool air was judged to be an effective reinforcer of unelicited GSRs, perhaps more effective than those used in previous studies.     

Providing help and desired relationship type as determinants of changes in moods and self-evaluations

Observed in 2 initial studies was converging evidence that helping improves the helpers' moods and self-evaluations. In these studies Ss induced to help showed improved moods and self-evaluations relative to Ss not given an opportunity to help. A 3rd study examined the moderating effects of desired relationship type on reactions to having helped. In this study Ss were led to desire either a communal or an exchange relationship with another. They then helped the other or were not allowed to help. Among Ss led to desire a communal relationship, but not among those led to desire an exchange relationship, helping was associated with greater improvements in moods than not helping. Helping tended to improve self-evaluations regardless of desired relationship type. However, this effect reached statistical significance only among subjects led to desire a communal relationship.     

Asymmetry of doubt in medical self-diagnosis: the ambiguity of "uncertain wellness".

In 2 studies Ss received a clear or an unclear diagnosis, indicating either disease or no disease. In Experiment 1, Ss responded to a hypothetical bacteria test. In Experiment 2, Ss performed 2 saliva tests purportedly measuring risk for pancreatic disorders. Responses to the unclear well diagnosis were unique in several ways. Ss thought the test more invalid, inferred a greater likelihood of illness from a 2nd identical result, saw the disorder as more pernicious, and held no self-protective beliefs about the test or the disease. Moreover, desire for treatment among these Ss was as great as among those receiving a clear diagnosis of illness. Possible mechanisms are discussed, as are potential applications to clinical issues and to the development and maintenance of hypochondriacal health concerns.     

Positive Emotions Speed Recovery from the Cardiovascular Sequelae of Negative Emotions

Two studies tested the hypothesis that certain positive emotions speed recovery from the cardiovascular sequelae of negative emotions. In Study 1, 60 subjects (Ss) viewed an initial fear-eliciting film, and were randomly assigned to view a secondary film that elicited: (a) contentment; (b) amusement; (c) neutrality; or (d) sadness. Compared to Ss who viewed the neutral and sad secondary films, those who viewed the positive films exhibited more rapid returns to pre-film levels of cardiovascular activation. In Study 2, 72 Ss viewed a film known to elicit sadness. Fifty Ss spontaneously smiled at least once while viewing this film. Compared to Ss who did not smile, those who smiled exhibited more rapid returns to pre-film levels of cardiovascular activation. We discuss these findings in terms of emotion theory and possible health-promoting functions of positive emotions.     

Sequential letter and word recognition in deaf and hearing subjects

To examine the processing of sequentially presented letters of familiar and nonsense words, especially among Ss of vastly differing experience on sequential tasks, three groups of Ss were tested on letters of words spelled sequentially on an alphanumeric display and on letters of words fingerspelled. These were a deaf group (N=33) with little or no hearing and who varied in their fingerspelling ability; a staff group (N=12) who taught fingerspelling and were highly proficient; and a hearing group (N=19). Of principal interest was the finding that the hearing Ss did better on nonsense letter recognition, while the deaf group did better on word recognition. Word length was important except to the staff Ss on fingerspelled words, which also suggests that concentration on fingerspelling proficiency forces attention to the whole word and not its component letters. Hearing Ss, who are the group faced with an unfamiliar task, seemed to attend to each letter and hence had more difficulty with recognition of the longer unit.     

Image, issues, and ideology: the processing of information about political candidates

Ss watched a videotaped nonpolitical speech by a male political candidate that conveyed either a favorable or an unfavorable image. Then they heard an excerpt of a radio program in which the candidate was described as holding either conservative positions or liberal positions on a series of specific issues. The impact of the candidate's speech on evaluations of him decreased over time. However, Ss used the speech as a basis for judgment only when the candidate's issue stands had unfavorable implications. When Ss learned the candidate's issue stands 24 hr after they heard the speech, they based their evaluations on their personal agreement with these stands. When Ss learned the candidate's issue positions immediately after the speech, however, they based their evaluations on the ideological implications of the issue stands instead.     

Self-Actualization of “Paranormals”

A sample of 56 Ss nominated by others as paranormals and self-stated as experiencing paranormal (occult) phenomena, were administered measures purportedly reflected dimensions of the self-actualization concept. Ss reported both their interest in, and experience of, 15 areas of paranormal phenomena. Ss were given the Marlowe-Crown Social Desirability Scale (measuring ego-defensiveness), Shostrom's Self-Actualization Test (POI), and an Aphorism test (designed to measure degree of “expanded awareness”). Ss scores were compared with various normative and experimental group scores for the three tests. Although statistically significant differences were rare, there was usually a trend for paranormals to score in the direction of self-actualization on most measures.     

Human sensory dominance

Human Ss matched an auditory and a visual stimulus for subjective magnitude. Then each stimulus was used as a cue in a reaction time task. On occasions when both stimuli were presented simultaneously, Ss’ responding was seen to be dominated by the visual stimulus. Of further interest was the finding that on some occasions of simultaneous light-tone presentation Ss were unaware that the tone had been presented. This apparent prepotency of the visual over the auditory stimulus was seen to persist across a variety of experimental conditions, which included giving Ss verbal instructions to respond to the tone when both stimuli were presented simultaneously.
