Eye movements were recorded in 10 adult subjects during the viewing of fiction and nonfiction films. Individual differences in scan paths for fiction films were found to be relatively small. Generally, eyes concentrated on the screen center when looking at characters and objects in rapid motion. Scan paths through the screen were observed in special cases, for example, in the case of a dialogue between two characters. No differences emerged in scan paths for the same clip presented in black-and-white and color versions. Results are relevant for both filmmaking and research on perceptual and cognitive strategies involved in processing motion pictures.
A list is given of 60 basic references (monographs and general reviews) in the field of evoked potentials and event-related brain potentials applied to vision research in man.
Eyeblink signals and evoked potentials were recorded and averaged in humans during the tachistoscopic presentation of gratings at various spatial frequencies and levels of luminance. It was confirmed that at high spatial frequencies and low levels of luminance the latency of evoked potentials increased and their amplitude decreased. At the same time there was a longer inhibition of the eyeblink, which was more precisely timed on the stimulus. This points to the existence of a central system that regulates the eyeblink in accordance with the attention involved in visual information processing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
