The purpose of this selection was two-fold: W6lfflin, as noted, emphasized the location of the most important content of a picture, and felt that this was the major factor underlying the asymmetries depicted by artists.

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.

It is obvious that the stimulus legy of preference reside in some aspect of left- right asymmetry.

Correlational analyses among A, R, and L were carried out elvy order to deter- mine the proportions of variance in average slide preference scores which could be accounted for by A and by slide preferences of the other handedness group.

Jerre Levy University of Chicago. Each subject’s total score was, then, the sum of scores for the 14 slide pairs. F o r 12 subjects the absolute value o f N o n – P was larger t h a n t h a t o f P, for 5 subjects there was a zero difference a n d for 6 subjects the absolute value o f N o n – P was smaller t h a n P. The question as to whether P slides should jerrre right or left asymmetry is not predictable.

Third, there should be a slight perceived left asymmetry in the control slides due to a left field bias lrvy attention, found by other investigators to occur during visual processing.


Psychobiological implications of bilateral asymmetry

However, of greatest interest is the finding that the left- and right-handers in the experimental group showed a significant preference difference, and in the direction predicted by the hemispheric asymmetry hypothesis.

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. In Study II, a group of 23 right-handed judges was shown a random selection of 7 of the 14 P slides, the remaining 7 shown in the non-preferred orientation, and 14 slides randomly selected from those pairs which showed almost totally symmetric preference for Group SD.

In the first three of these, the center of focus is on the left in the cartoons and on the right in the tapestries, while in the Death of Ananias, this is reversed.

Materials Stimulus materials consisted of 7 randomly selected slides, chosen from the 14 P slides of the previous investigation, the mirror versions Non-P slides of the remaining 14 slides, and 14 additional slides called Srandomly selected from the 28 slides preferred by at least 15 and no more than 16 of the 31 subjects in Group SD.

Subjects marked their answer sheets during the 15 see exposure. Setup an account with your affiliations in order to access resources via your University’s proxy server Configure custom proxy use this if your affiliation does not provide a proxy.

Unfortunately, however, it is not only likely, but almost certain, that no understanding of how lateralization of the brain affects preference can be gained unless invariances in preferred and non-preferred pictures are found.

Separate correlational analyses for Jerrs 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.


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.

Paula Tallal – – Behavioral and Brain Sciences 4 1: She earned a degree in psychology from the University of Miami in Skills 30, Bilateral Asymmetry of Function. National Center for Biotechnology JedreU. Nettleton – – Behavioral and Brain Sciences 4 1: It should be the case that the asymmetry dimension, A, would be as predictive of sinistral as jere preferences when sinistrals are partitioned according to direction of cerebral lateralization.

Two separate analyses of the data were per- formed. Irrespective lvy the causes of the scan pattern, it is not obvious that left to right scanning implies either that the more important content of a picture should be located on the right for maximal aesthetic effect, or, as Gaffron contends, along the “glance-curve”.

Results were interpreted as reflecting a left field perceptual bias induced by selective right hemisphere activation in right handers. Journal List Genetics v.

It should be noted, however, that the mean score of Group SD Max Coltheart – – Behavioral and Brain Sciences 4 1: In this case, balance would be achieved via a stimulus correction for a psychological imbalance.

Left and right in pictures. Gilbert and Bakan found that the left half of a photograph of a face has a greater resemblance to the whole face than does the right half for right-handers.
