GRIDLAT: Toward a constructivist methodology to investigate brain lateralization

Verbal conceptual processes and emotional experience (in general, as well as positive vs. negative) are phenomena that appear to have lateralized correlates. A general method is herein put forth by which researchers can investigate the lateralization of various constructive processes in the brain. The technique, called GRIDLAT, is a computerized repertory grid protocol that displays element and construct information to a single hemisphere (vis à vis visual field) at a time during grid elicitation. GRIDLAT is described in detail. Then some preliminary findings are described, and several dependent variables possible in studies employing methods such as GRIDLAT are discussed.
