Rorschach space response and aggression

The study investigated the construct validity of the Rorschach space response by factor analyzing the stress-coping reactions to highly stressful conditions. Self-report reactions to stress of 173 medical students measured on the Habits of Nervous Tension showed that space responding loaded highest on a factor identified as "anger affect" and secondarily loaded negatively on a factor identified as "regressive withdrawal." Findings were consistent with earlier results for space response on validity.     

Androgyny,depression, and self-esteem in irish homosexual and heterosexual males and females

An examination was made of the following research questions: (a) Do Irish homosexuals and heterosexuals differ in the frequency of their classification in sex-role categories? (b) Is sexual orientation related to psychological adjustment? (c) Is androgyny related to psychological adjustment? Subjects were 112 Irish men and women who were administered Bem's Sex-Role Inventory, Rosenberg's Self-Esteem Scale, Zung's Self-Rating Depression Scale, and a questionnaire. Results indicated that Irish homosexuals were classified more frequently than Irish heterosexuals as androgynous. Homosexuals did not differ from heterosexuals in self-esteem or depression scores. Among these Irish subjects, psychological sex-role category is a more powerful influence on psychological health than actual sexual orientation. It is not whether you are homosexual or heterosexual that affects your psychological health, but how you perceive your own psychological masculinity and femininity.     

Processing of visual syntax in a globally aphasic patient

A globally aphasic patient was trained on a computerized visual communication system. His ability to comprehend reversible locative prepositional phrases after training was studied and compared with the performance of Broca's aphasics on a similar task. This patient's ability to generalize symbols for actions was also investigated. The results demonstrate our patient's capacity to master a formal visual syntax in the absence of natural language and illustrate how this capacity may be used successfully in a visual communication system. A problem in generalizing symbols for actions is demonstrated, suggesting that certain heuristic and cueing capabilities in the approach may be helpful.     

From Site Unseen to Experiential Learning: Religious Studies in the “Discover Chicago” Model

This paper examines David Kolb’s theory of experiential learning and its usefulness in developing religious studies courses in a ‘Discover Chicago’ program, wherein students spend an intensive ‘immersion’ week before the start of the autumn quarter touring, researching, interviewing, discussing, and analyzing a variety of phenomena in the Chicago metropolitan area. Then, during the quarter, they critically revisit issues raised by the immersion week, probing more deeply and letting their initial impressions take on more mature reflective forms by engaging in extensive reading and systematically relating text with experience. Finally, research projects are developed, being outgrowths of the activities of the summer week and the readings and discussions from the first part of the quarter.     

Intentional versus unintentional use of contingencies between perceptual events

In three experiments we studied human ability to use statistical contingencies between visual stimuli (flankers and targets) to improve performance in a letter-digit classification task. We compared the performance of explicitly informed subjects with that of subjects who were told nothing of the contingencies. Simultaneous presentation of flankers and targets (Experiment 1) produced evidence of unintentional contingency use by both informed and uninformed subjects. When stimuli on trialn predicted target stimuli on trialn+1 (Experiment 2) there was no evidence of unintentional processes, but informed subjects showed strong evidence of using intentional prediction strategies. When flanker onset preceded target stimuli presentation (Experiment 3), evidence of contingency use by both informed and uninformed subjects was found, but the data illustrated qualitative differences in response style (e.g., speed-accuracy tradeoffs) between the two groups. Intentional and unintentional uses of contingencies between perceptual events are qualitatively distinct with respect to the time frame in which they can be applied and the performance patterns they produce. Finally, we argue that the unintentional processes studied here are implicit in nature.     

Reaction time, intelligence, and attention

The roles of attention in reaction time and in the relationships among reaction time, intelligence, and achievement were analyzed. The subjects were 105 seventh-grade children. The results were generally consistent with most studies involving the Hick paradigm: both mean reaction time and the standard deviation of reaction time correlated with the intelligence and achievement measures used. Reaction time measures were correlated with attention and perceptual speed as well as with general intelligence, or g. Implications of these results for current theories linking reaction time and intelligence are discussed.     

Reversal and nonreversal shifts in autistic children

Reversal and nonreversal shifts in nineteen 2- to 14-year-old autistic children were studied. Each child was taught both a reversal and nonreversal shift discrimination task. The reversal shift condition entailed teaching the child to respond to one (the S+) of a pair of stimuli during training and subsequently reversing the S+ during testing. The nonreversal shift condition consisted of teaching the child two unrelated discriminations during training and testing. The results indicated that the older autistic children did better on reversal shifts than younger children who did better on nonreversal shifts. These findings are consistent with those for normal children.     

Modes of information integration and Piagetian measures of concrete operational thought

The purpose of the study was to investigate the relationships between modes of information integration and performance on a variety of Piagetian concrete operational tasks. The sample consisted of 180 6- to 8-year-olds. Factor analysis of the Piaget tests revealed five interpretable factors: conversation of substance—equality, conservation of substance— inequality, conservation of number, class inclusion, and matrices. Factor analysis of the marker tests for information integration revealed two factors: simultaneous and successive. All the Piaget measures, with the exception of class inclusion, were related to the simultaneous factor. Class inclusion was weakly related to the successive factor.     

EYEMOVEMENT AND PERCEPTUAL ADAPTATION TO CURVATURE

It is proposed that perceptual adaptation is basically an immediate localized consequence of stimulation but can become generalized through a process of conditioning by temporal contiguity. Experimental conditions were designed to assess the aftereffect of adaptation to curvature under various combinations of eye position and eye movement activity for adapting vs. test periods. In general, the results support the hypothesis that perceptual adaptation to a visual stimulus can be associated with the nonvisual factors present at the time the adaptation occurs.
