A suggested hemispheric basis for the guided search model

Abstract

Experimental findings not suiting the guided search model (GSM) of Cave and Wolfe (1990) and Wolfe (1994) and the modified guided search model (mGSM) of Efron and Yund (1996) are reviewed. Assumptions which explain these discrepancies are added. Thus two possible alternative models are obtained. According to both models the preattentional parallel processing stage of the GSM is related to the right hemisphere, while the attentional stage is related to the left hemisphere. Experiments determining whether one of these models is correct are suggested.
