The P300 component of the average evoked potential was recorded at Pz during two divided visual field tasks. During a lexical decision task, reaction time and P300 latency were faster to stimuli in the right visual field, indicating that the latency of the P300 may be a useful measure in laterality research. A right visual field advantage was obtained for reaction time in a face perception task and the P300 latency difference showed a similar but non-significant advantage. Use of the P300 latency to assess the validity of the assumptions underlying the application of an additive factors model to divided visual field studies of cerebral assymetry was discussed. The present evidence suggests that the assumptions are valid. / Arts, Faculty of / Psychology, Department of / Graduate

The thesis describes research investigating differences between the two hemispheres in automatic and in attentionally controlled processes. It is suggested that the interaction between these two processes may be a source of hemispheric differences. Three different paradigms that each imply different definitions of automatic and attentionally controlled processes are used: A paradigm used to demonstrate illusory conjunctions, a modified priming paradigm and a modified Stroop-task. Converging evidence from all three paradigms indicates that automatic processes are common to both hemispheres. Lateral asymmetries only emerge in attentional effects. For verbal information, selective attention mechanisms in the left hemisphere are found to be selective for left hemisphere items only, whereas right hemisphere mechanisms are sensitive to information from both hemispheres. The right hemisphere appears to be able to give some automatic support to attended verbal processing in the left hemisphere, while the reverse seems to be more difficult. / Arts, Faculty of / Psychology, Department of / Graduate
