Cinema seating in right, mixed and left handers.

摘要

Two hundred and sixty four right-handed, 246 mixed-handed and 360 left-handed students were requested to indicate on five maps of cinema halls what place they would choose. All three handedness groups showed a preference for the right and a corresponding directional bias towards the left space. However, they differed significantly from each other on the magnitude of this bias which was most pronounced in right and less in left handers. It is assumed that lateralized mechanisms underlying such biases have developed evolutionarily and serve right-handed persons best. Non-dextrality considerably reduces their phenotypic expressions, but even left-handedness does not reverse the directional bias towards the left. It is also hypothesized that right, mixed and left handers differ in a large number of behavioral choices and strategies, modeled by cerebrally lateralized mechanisms and that the cinema seating preference is only one of them.
