The relationship of vocational decidedness and satisfaction with dogmatism and self-esteem

The purpose of this study was to investigate the relationship of levels of vocational decidedness and the satisfaction or dissatisfaction of one's level of vocational decidedness with dogmatism and self-esteem. The results indicated that vocationally decided and undecided subjects represent uniquely different populations on measures of dogmatism and self-esteem.

The roles of contour and luminance distribution in determining perceived centers within shapes

Two sources of visual information that likely could be employed by the perceptual system in locating the centers of bounded shapes—boundary configuration and luminance distribution—have been perfectly confounded in every study thus far aimed at investigating perceived centters. Observers, using either a revolving or stationary x-y plotter, made judgments on the location of centers within either revolving or stationary shapes of both uniform and varied luminance distributions. Results indicate that the location of perceived centers depended predominantly upon boundary contour and was affected by the distribution of luminance within these edges to a much lesser degree.     

Autonomous processes in comprehension: A reply to Marslen-Wilson and Tyler

A criterion which has been proposed for distinguishing minds from computing systems is examined from the point of view of some current work on computer induction.     

Intrahemispheric differentiation of vowels: Principal component analysis of auditory evoked responses to computer-synthesized vowel sounds

Auditory evoked brain responses (AER) were recorded in response to a series of synthesized vowel sounds which varied in formant bandwidth. Multivariate analyses indicated that changes in AER component structure recorded from different scalp regions over both hemispheres varied as a function of different vowel sounds and formant bandwidth. No interhemispheric differences in scalp AER distributions were noted.     

Interdisciplinary agreement in the diagnosis of headache types

The degree of agreement in independent diagnosis of headache by a neurologist and a clinical psychologist was determined to be 86.4% in a series of 66 consecutive patients. Fifty-five percent of the disagreements were due to the patients' giving different information to the two assessors. This source of disagreement was associated with the patients' having had previous psychiatric treatment.This research was supported in part by Grant NS-15235 from the National Institute of Neurological and Communicative Disorders and Stroke.     

An analysis of spatial orientation test performance

Spatial Orientation ability correlates with important criteria such as achievement in calculus and physics, but this ability has not been investigated systematically. Performance on individual items adapted from a standard test of Spatial Orientation was studied. Subjects judged whether aerial views would be seen by an observer oriented in various ways. For practiced subjects, the time to answer items was an approximately linear function of the number of abstract spatial dimensions on which the aerial view and the observer's orientation were consistent. Practice led to lower error rates and lower intercepts for the response-time functions. Subject's ability correlated with the linearity of their response-time functions suggesting that lower ability subjects fail to code one or more spatial dimensions. A model specifying serial, self-terminating comparison of abstract spatial dimensions is proposed as an ideal which subjects approach after practice.     

Capacity and strategy for syntactic comprehension after left or right hemidecortication

The left and right hemispheres perform different encoding and decoding operations on a syntactically complex sentence in order to identify its meaning. Hemispheric asymmetry for syntax involves not only variations in capacity, but also differences in the strategy used to effect similar language performance.
