Divided Visual Field Studies of Cerebral Organisation

The divided visual field paradigm: methodological considerations.

The divided visual field methodology has been used to examine a wide variety of lateralised processes. When conducting such studies it is important to employ a number of strict controls in order to maximise the effectiveness of the paradigm for examining the processing of stimuli by each hemisphere. The use of these controls is discussed in this paper. The following issues are discussed: select...

Evidence for stimulus-response compatibility effects in a divided visual field study of cerebral lateralization.

The question addressed here was whether lateral asymmetry of processing might be influenced by response position, a factor which is usually considered irrelevant in divided visual field studies of cerebral lateralization. For this purpose a lexical decision task, which had previously been investigated with lateral unimanual two-finger choice reactions (Heister et al. 1983) was carried out under...

Cerebral aneurysms presenting with visual field defects.

ANEURYSMS occur more frequently within the cranium than elsewhere in the body, and most-75 to 85 per cent. according to Walsh (1964)-are situated on the anterior part of the circle of Willis. In this region they are closely related to the primary visual pathways and motor nerves to the eye. Extra-ocular muscle palsies are well recognized by ophthalmologists as indicative of such lesions, partic...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
