Laterality and field dependence

The purposes of this study were (1) to replicate a right visual-field advantage for a version of the Embedded Figures Test modified for tachistoscopic presentation and (2) to test for a relationship between field independence and performance on modified Embedded Figures Test items presented to the right visual-field. 34 right-handed subjects were presented Embedded Figures Test items to the left, center, and right visual-fields for 150 msec. The Group Embedded Figures Test was also given. Results showed a right visual-field advantage on the modified embedded-figures test and (2) a negative relationship between Group Embedded Figures Test performance and right visual-field scores. These findings were discussed in terms of the differences between the two versions of the embedded-figures test, memory for simple figures, specificity of judgment, and sustained versus tachistoscopic perception. A tentative conclusion suggests that a better internal representation of the briefly presented complex figures places field-independent subjects at a disadvantage on the modified version of the test.     

Effects of figure-ground reversal on the visual-perceptual and visuo-motor performances of cerebral palsied and normal children

Individuals with brain damage often encounter visual perceptual and visuo-motor difficulties. Studies have indicated an improvement in exceptional individuals' performances when the colors of figure-ground materials were reversed. Effects of reversals were studied for spastic cerebral palsied and normal children's scores on the Developmental Test of Visual-motor Integration and the Motor-free Visual Perception Test. Normal children performed better than the cerebral palsied children on all tests; the cerebral palsied children performed best on the reversed-format Motor-free Visual Perception Test. Reversal affected neither group's scores on visual-motor integration.     

Improving the test-taking skills of learning-disabled students

16 learning-disabled second- and third-grade students were matched on previous years' achievement scores and grade and assigned at random to experimental and control conditions. Students in the experimental condition were given 8 20-min. sessions of training in test-taking skills particular to the Stanford Achievement Test. Analysis of test scores indicated trained students scored significantly higher on one subtest of a shortened version of the test than students who had not been trained.     

Longitudinal changes in time estimation in affective disorders: a preliminary study

8 patients with hospital diagnoses of major affective disorder were studied by repeated measurements of time estimation using the three different methods of metronome adjustment, verbal estimation and operative estimation (production) of short time intervals. Retrospective estimations of longer intervals were also studied. The diagnoses were evaluated according to DSM III criteria. The degree of mental disturbance was rated with subscales of the Comprehensive Psychopathological Rating Scale. Earlier findings had indicated that manic patients tend to overestimate short time intervals and that some depressed patients underestimated time, but some investigators have reported different results. A longitudinal study could possibly support the earlier findings if the time estimations should vary with the clinical states of the patients. Such a variation was suggested by the results of 5 of the 8 patients. In several cases there were statistically significant correlations between the results of time estimations and the rating scores. This partly supports earlier findings. Associations between time estimations and changes in clinical state seem to be present in some cases of major affective disorders. Operative estimations were best correlated with ratings in most cases.     

Compliance with homework to employ self-instructions in controlling ice water pain: an analogue to counseling

40 women were taught to use self-statements to cope with pain caused by ice water. The trainer used four different strategies for reassigning a homework task of using self-statements to cope with pain produced by immersing one hand in ice water. The strategies were equally effective in eliciting compliance with the homework assignment.     

Cognitive styles: illusory phenomena

The relationship between cognitive style and illusion magnitude was examined using the assimilation and contrast Delboeuf distortions. As in previous research, field dependence correlated positively with assimilation; however, a significant negative correlation with contrast was also found, suggesting that, while field dependence may involve the illusory integration of the stimulus field, field independence may involve its equally illusory differentiation.     

Sequential effects in dimensional contrast

Two experiments examined pigeons' response rates during short trials signaled by stimuli closely spaced along a wavelength continuum. In Experiment 1 separate halves of the continuum were correlated with different reinforcement schedules. In Experiment 2, the middle stimulus was accompanied by a lower probability of reinforcement than were the remaining wavelengths. Both procedures resulted in dimensional contrast “shoulders,” seen as relatively enhanced or depressed response rates in the presence of stimuli between the extreme of the continuum and the border separating the positive and negative stimuli. Sequential analyses addressed possible contributions of the following interactions: (a) local contrast, seen when rate during a given schedule depends on the schedule in the just-preceding trial; (b) modification of local contrast by the similarity of the signaling stimuli (P. Blough, 1983); and (c) schedule-independent rate contrast, seen when rate in a given trial depends on the rate controlled by the stimulus that accompanied the just-preceding trial (Malone & Rowe, 1981). Dimensional contrast functions were similar when isolated according to the schedule, to the similarity of the signaling stimulus, and to the response rate of the just-preceding trial. The interactions noted above do not appear to make important contributions to this effect.     

On narcissism and post-narcissism: Psychology and theology in context

A contextual approach to narcissism is developed in which theology is seen to articulate simultaneously with psychological needs and cultural values. Some implications of the psychology of the self for theology and culture are discussed in this framework.The author wishes to express his gratitude to Dr. Larry K. Graham for his comments on an earlier version of this paper.Dr. Fallot is a psychologist on the staff of the Student Counseling Service, University of Illinois at Chicago, P.O.

Induction of depressive affect after prolonged exposure to a mildly depressed individual

Scores on the Beck Depression Inventory (BDI) were periodically obtained from the roommates of college students who exhibited a persistent mild depression over a 3-month period. For comparative purposes, BDI scores were also obtained from roommates of individuals who were transiently depressed and from subjects with nondepressed roommates. In comparison with control subjects, the roommates of persistently depressed persons displayed a progressive increase in BDI score over the course of the study.     

Contributions of elicitation to measures of self-control

Pigeons' not pecking or pecking constituted choice between a delayed, large reinforcer and an immediate, small reinforcer (self-control) and at other times between a delayed reinforcer and no reinforcer (omission). Both a tone and a keylight were tested as choice signals, and the delayed reinforcer was either response independent or response dependent. Pigeons pecked during the choice signals on over 95% of the trials in the self-control procedure, and pecked during the choice signals on over 75% of the trials in the omission procedure. Consistent pecking was observed with either the tone or the keylight as a choice signal, with the exception that a tone paired with a response-independent delayed reinforcer did not maintain pecking in the omission procedure. Pigeons pecked during more choice signals when delayed reinforcers were response dependent than when the delayed reinforcers were response independent. These results indicate that Pavlovian conditioning influences self-control experiments, especially in single-key procedures.
