Title: Crossed Hands and Closed Eyes
Ebbinghaus Empire Series 2013-2014
The data explore the relation between posture and tactile temporal processing. As our arms move through space we must keep track of their position to interact with the world. When the arms are crossed over the body midline there are a series of deficits observed. Specifically, when required to make temporal order judgements of stimuli delivered to each hand, performance can be up to 300% worse in the crossed posture compared to the uncrossed posture. Through manipulations of response demands, visual deprivation, and overall body posture, we explore the idea that the deficit arises from a conflict between frames of reference.
