Electrophysiological studies of human face perception. II: Response properties of face-specific potentials generated in occipitotemporal cortex.
In the previous paper the locations and basic response properties of N200 and other face-specific event-related potentials (ERPs) were described. In this paper responsiveness of N200 and related ERPs to the perceptual features of faces and other images was assessed. N200 amplitude did not vary substantially, whether evoked by colored or grayscale faces; normal, blurred or line-drawing faces; or...
متن کاملThe effects of hemispheric asymmetries and depression on the perception of emotion.
The present study investigated hemispheric asymmetries in the perception of positive and negative emotion. The moderating effect of depression on hemispheric asymmetries was also examined. Forty undergraduates were presented with happy and sad faces using a bilateral visual half-field design. Subjects were classified as depressed or nondepressed based on scores on the Beck Depression Inventory....
متن کاملDifferences between visual hemifields in identifying rapidly presented target stimuli: letters and digits, faces, and shapes
The right hemisphere has been shown to play a dominant role in processing of visuo-spatial information. Recently, this role has been studied in the two-stream rapid serial visual presentation task. In this task, two alphanumerical targets are embedded in left and right simultaneous streams of rapidly changing letters. The second target (T2) is identified better in the left than in the right vis...
متن کاملThe visual basis of category effects in object identification: evidence from the visual hemifield paradigm.
The basis for the category specific living things advantage in object recognition (i.e., faster and more accurate identification of living compared to nonliving things) was investigated in two experiments. It was hypothesised that the global shape of living things on average provides more information about their basic level identity than the global shape of nonliving things. In two experiments ...
متن کاملGerstmann’s syndrome in non- dominant hemisphere: a case report
Gerstmann’s syndrome is caused by a left (dominant) inferior parietal lesion, particularly involving the angular gyrus or subjacent white matter of the left hemisphere. We describe case of an 80 year old right handed man admitted to our hospital with history of sudden onset of blurred vision. At first in neurological examination, he had left hemonymus hemianopia and characteristic features of G...
