Deficits in temporal sequencing of verbal material: The effect of laterality of lesion

Temporal sequencing of verbal materials (digits, words, and geometric forms) presented in two sensory modalities (auditory and visual) to three groups of subjects (Broca's with left anterior lesions, patients with right hemisphere lesions, and normals) was examined. Each subject was asked to point to a set of stimuli in the same sequence as presented by the examiner. Results indicated that patients with left hemisphere lesions were more impaired on all tasks than the right hemisphere lesioned patients who, in turn, were impaired compared to normal controls. Response to auditory presentation was superior to response to visual presentation. Also, digits were the easiest for all groups, and words were easier than geometric forms. Of special interest was the finding which suggested that right hemisphere lesions are associated with impairment of verbal temporal sequencing under either auditory or visual presentation.     

A note on the gross configurations of the human auditory cortex

Gross inspection of 30 human brains (60 hemispheres) from patients without hearing impairment revealed the following configurations of gyri: one on left and two on right (14 of 30); two on left and two on right (11 of 30); one on left and one on right (3 of 30); two on left and one on right (1 of 30); and two on left and three on right (1 of 30). The last group has since been extended to include all combinations other than the first four and the proportions of these combinations appear to persist in larger tallies. Thirteen of the 30 brains displayed double gyri on the left while 25 had double gyri on the right. Seventeen of the 30 brains possessed a single gyrus on the left and four specimens had a single gyrus on the right. In general, the left side has a tendency to fewer gyral markings. The average cortical surface area on the left is 1198 mm² compared to 1380 on the right.     

The nonverbal mediation of self-fulfilling prophecies in interracial interaction

Two experiments were designed to demonstrate the existence of a self-fulfilling prophecy mediated by nonverbal behavior in an interracial interaction. The results of Experiment 1, which employed naive, white job interviewers and trained white and black job applicants, demonstrated that black applicants received (a) less immediacy, (b) higher rates of speech errors, and (c) shorter amounts of interview time. Experiment 2 employed naive, white applicants and trained white interviewers. In this experiment subject-applicants received behaviors that approximated those given either the black or white applicants in Experiment 1. The main results indicated that subjects treated like the blacks of Experiment 1 were judged to perform less adequately and to be more nervous in the interview situation than subjects treated like the whites. The former subjects also reciprocated with less proximate positions and rated the interviewers as being less adequate and friendly. The implications of these findings for black unemployment were discussed.     

Disagreements and self-esteem: Support for the competence-reinforcement model of attraction

The competence-reinforcement model of attraction (Byrne & Clore, 1967) theorizes that interpersonal disagreements produce negative affect and decrements in personal competence. Subject dislike for disagreeing strangers has been a frequent and reliable finding, but the theoretical issue of whether disagreements elicit negative affect because they threaten one's sense of personal competence has been less thoroughly investigated. The present study examines the relationship between attitude disagreements and self-esteem. On the basis of the competence-reinforcement model of attraction it was hypothesized that disagreements would produce decrements in selfesteem, and that the decrements would be most pronounced among subjects expressing the greatest dislike for the disagreeing stranger. Both hypotheses were supported, and it was concluded that the competence-reinforcement model provides an adequate account of both attraction and self-esteem loss.     

Task-hemispheric integrity in dual task performance

A condition of task hemispheric integrity is predicted to result in a dual task situation when the central processing and response components of each task are associated exclusively with a given cerebral hemisphere. The prediction that this condition will generate more efficient time-sharing is tested in a series of four experiments. In experiment 1 the prediction is confirmed when a spatial (tracking) and verbal (letter memory search) task are time-shared, and the hand assignment to task responses is manipulated. In experiment 2 a spatial variant of the memory search is used instead of the verbal letter search, and hand assignment effects are not obtained, since when two spatial tasks are time-shared an integrity assignment is impossible. Experiment 3 validates the hemispheric lateralization of the two single task variants of the memory search task, while experiment 4 establishes the separate “spatial’ and “verbal” resource demands of the two variants by observing their differential interference with concurrent spatial and verbal tasks.     

Career choice and orality

The field of vocational psychology is replete with schemata for the determinants of career choice in adulthood (e.g., A. Roe, The psychology of occupations. New York: Wiley, 1956; D. E. Super, The psychology of careers. New York: Harper &Row, 1957; J. O. Crites, Vocational psychology: The study of vocational behavior and development. New York: McGraw-Hill, 1969). A view not given much weight in empirical research in this area is that of psychoanalytic theory relating career choice to unresolved childhood conflicts and their derivatives. To examine the validity of this psychoanalytic prediction, students' Rorschach protocols were analyzed to yield an index of frustrated oral needs. The students were given decks of careers to rank from most to least preferable. Results showed that the ranking of the oral careers was a function of the Rorschach index of frustrated oral needs for women only but not for men.     

Acting on one's attitudes: Procedures for linking attitude and behavior

Two investigations examined the determinants of correspondence between attitudes and behaviors. The first investigation examined the relationship between previously measured attitudes toward affirmative action and subsequent behavioral verdicts in a sex discrimination court case. In this basic situation, correspondence between measured attitudes and judicial decision-making behavior was minimal, for both low-self-monitoring individuals and high-self-monitoring individuals. Increasing the availability of attitudes generated substantial correspondence between attitudes and behavior for low-self-monitoring individuals, but not for high-self-monitoring individuals. Increasing the relevance of attitudes generated substantial correspondence between attitudes and behavior for both low-self-monitoring individuals and high-self-monitoring individuals. The second investigation examined the decisions of individuals with favorable attitudes toward psychological research to volunteer to participate in extra sessions of a psychology experiment. Once again, increasing the relevance of attitudes was an effective procedure for inducing individuals to translate existing attitudes into corresponding behaviors. These empirical outcomes are interpreted within a theoretical framework that specifies the interactive contributions of availability, relevance, and self-monitoring to the creation of “action structures” that link attitudes and behavior. Practical implications of this viewpoint are discussed.     

Affective isolation as a coping strategy for persons with low and high amounts of life stress

Previous research has investigated two diverse operational definitions of stress, experimentally induced, short-term stress and long-term, life stress. The purpose of this study was to intersect these two research methodologies and determine the effect of a laboratory-induced stress (failure feedback) on persons with differing levels of life stress. Women with high or low amounts of life stress were given failure feedback, no failure feedback, or a cognitive coping strategy (affective isolation) in addition to failure feedback. Failure feedback increased self-reported anger and anxiety immediately following feedback and also after a follow-up test and decreased expectations about performance for the second test. Affective isolation significantly reduced anger and anxiety but failed to affect expectations. Women with high amounts of life stress reported significantly less anxiety than women with low amounts of life stress in response to failure feedback. These results were interpreted within C. D. Spielberger's (in C. D. Spielberger & R. Diaz-Guerrero (Eds.), Cross-cultural anxiety, New York: Wiley, 1976) cognitive model. It was proposed that differing levels of previous life stress cause people to make varying judgments about the degree of threat in a short-term stressful situation. Persons with high amounts of life stress may not be aroused in response to short-term stress because they perceive the short-term stress as only a “drop in the bucket” compared to the other events which they have experienced.
