All subjects calling themselves “ambidextrous” were included with the left-handed group for theoretical reasons [26]. All subjects were tested in a single group session.

This inter- pretation would be not only consistent with Wflfflin’s, Schlosser’s and Oppf’s conclusions, but also with the stress on balance in paintings as a first determinant of good art. In one, average P, Non-P, and S asymmetry scores were determined for each subject, averaging over slides in each category, and in the other, average asymmetry scores were determined for each slide, averaging over subjects.

The glance-curve begins in the left foreground, moving up and toward the background, then curving toward the right. She then became a professor at the University of Chicago. Views Read Edit View history. During the last 10 yr, and particularly during the last 5 yr, more and more psychologists have come to recognize the pervasive consequences for psychological function which result from cerebral lateralization.

Psychobiological implications of bilateral asymmetry

Stein – – Behavioral and Brain Sciences 29 3: Neither of these factors even approached significance for any of the four groups classified by handedness and sex, and subjects within each category were consequently combined across sessions.

Fourth, whichever category, P or Non-P, has left asymmetry, should be perceived as more asymmetric than the category having right asymmetry, since in the former case, psychological asymmetry will add to stimulus asymmetry, and in the latter case will subtract from it.


Perception of bilateral chimeric figures following hemi- spheric deconnexion. They may even seem to conflict with the conclusions of Schlosser, Wblfflin and Opp6 to the effect that the most important content of works of art are located in the right half of the picture. History of Western Philosophy. Enter the email address you signed up with and we’ll email you a reset link.

Please study each slide carefully in order to determine its balance with respect to the left and right sides of the slide. Thus, for any subject, a positive score indicated that his preference was similar to that for Group SD, a ldvy score indicated the opposite preference, and a score of zero indicated no relationship with the preferences of Group SD.

Direction of gaze and distribution of cerebral thought process. When dextral preferences are very weak S slidesthere is a slight, but significant, perceived left asymmetry.

If the jrere of importance or interest, or if these are equal on left and right, the greater heaviness, is on your left, check the column under LEFT and if on your right, the column under RIGHT.

In Cerebral Hemisphere Relations, J. Raquel and Ruben Gur for helping her to select the 97 slides used in this study from a total of almost California Institute of Technology, Paul Davies – – Research in Phenomenology 35 1: Jerre Levy born April 7, is an American psychologist and researcher of the brain.

The results of the present investigation seem to show also that the human aesthetic sense is profoundly affected leby the fact that the human brain is laterally lvey. If so, monolingual readers of Hebrew or Arabic would nerre the opposite versions of such pictures from those preferred by readers of European languages. Neither comparison yielded a significant difference, although the mean score of positive-scoring dextrals Aspects of genetics in psychology.


It should be noted that R and L scores were so assigned that any P slide shown in Study II should, on the average, have a positive R score, while any Non-P slide should, on the average, have a negative R score.

To assert that a particular distal cause is jwrre is not to suggest the leevy of the causal chain by which the consequence is effected. Information processing and higher psychological functions in the disconnected levj of commissurotomy jrere. Materials Ninety-seven vacation slides, whose subject matter included street scenes, architecture, wildlife, and natural scenery, 65 contributed by the author and 32 contributed by a colleague, were placed in a slide projector carousel labeled “A”random as to order and random as to front-back orientation.

Table 1 displays the results. Separate correlational analyses for P and Non-P slides Table 5 and for S slides Table 6 revealed that A was the sole significant predictor of dextral preference R in P and Non-P slides, being unrelated to sinistral preference Lwhile A had no predictive capacity for preferences in S slides, but L and R were fairly strongly related. A left-right asymmetry in either receptor or effector systems would be clearly disadvantageous to an animal with the capability of directed movement in response to a reality in which the direction of asymmetry is random.

Trevarthen reasoned that in an animal with laterally specialized functions in the two sides of the brain, selective hemispheric activation could and would emerge from cognitive activity specialized in a single hemisphere and would be reflected in an orientation reflex, or its covert homologue, an attentional bias, to the contralateral half of space.
