Psychobiological implications of bilateral asymmetry

She has also found evidence that the left hemisphere specializes in linear reasoningwhile the right brain is more involved in holistic reasoning. Fifth, the degree of per- ceived asymmetry in P and Non-P slides should be equal when compared after the control slide baseline has been subtracted out, since, once this is done, psychological asymmetry is removed.

Lateral dominance and aesthetic preference | Jerre Levy –

The Canadian Student Journal of Anthropology 21 1: Lateral organization, perceived depth and title preference in pictures. The investigators concluded that “. In this case, balance would be achieved via a stimulus correction for a psychological imbalance. One would guess that one of the two factors derives from cerebral lateralization, that the other is extrinsic to it, and the two variables are negatively correlated in S slides for subjects with typical dextral brain organization.

In the slide-analysis, slide-specific asymmetry scores A were assigned to each of the 28 slides. Handedness was determined by self-classificationinto one of three categories: Jerre Levy University of Chicago.


This jefre demonstrated by reversing the face and comparing the original and reversed faces to the same face composed of two left halves or two right halves.

Though the present investigation offers strong confirmation for the role of cerebral lateralization in determining aesthetic preference for mirror image pictures, it provides no clue as to why this should be so, the nature of any jerte which may be present in preferred pictures, nor how the direction of cerebral lateralization interacts with such invariances if they are present.

A Model for the Genetics of Handedness

Each slide was then projected for 15 sec on to a standard projection screen located in a classroom, followed immediately by the next slide in the sequence, with subjects usually marking their answer sheets during the last 5 see of each projection. The asymmetry of human neurological organization was, for over a century, of concern only to neurologists and neurosurgeons.

Neuropsychologia 12, In Gedanken zur Kunstgeschichte, Schwabe, Basel, Whether preferences for mirror-symmetric pictures derive from Western reading habits, brain lateralization, or both, the mechanisms by which these factors may affect aesthetic responses have not been specified. I t is a p p a r e n t l y the case that, in general, when a n a s y m m e t r i c pre- ference is manifested b y right-handers, the preferred scene is the one with the m o r e i m p o r – t a n t content, or, if this is equal, the greater heaviness, on the right.

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 Cerebral Hemisphere Relations, J.

Norman Adler for allowing her to duplicate 32 of his vacation slides, and to Drs. The preferred version was labeled ” P ” and was assigned a weighted score which was the Z-equivalent of the obtained X2, while the non-preferred version, ” N o n – P ‘was assigned a negative Z- equivalent. Each subject’s total score was, then, the sum of scores for the 14 slide pairs.


Received23 October Abstract–Left and right handers were found to differ in their preferences for mirror versions of vacation slides.

Balance is to be determined on the basis of two criteria: Am J Hum Genet. She states, “All objects within the range of this path are recognized spontaneously, while we must look separately for those located outside, i. However, the deviations of both groups from random expectation were so small that the left- and right-handed groups did not differ from each other, and the interpretation of their findings remains in doubt.

An ,evy was made to select slides which, rather than merely recording some vacation scene, might be perceived as appealing or interesting by viewers. The preference variances for left-handers L scoreshowever, did not differ F 1. Minor hemisphere dominance for certain visuospataial functions. Refinements designed to explain relevant qualitative facts are proposed and discussed. Males and females within each handedness category were then compared, and for neither right-handers nor left-handers did they differ significantly, nor even ap- proach significance.

Two separate analyses of the data were per- formed. Dyspraxia following division of the cerebral commissures.
