dc.description.abstract | Lateral eye movement (LEM) and finger pulse volume
(FPV) measures were taken while subjects responded to
questions incorporating both a cognitive component,
Visuo-spatia 1 or verbal processing, and an emotional
component, excitement or fear= Initial LEMs immediately
following stimulus offset and predominant LEM direction
during a 10 second period were recorded by EOG. Both LEM
measures and FPV did not yield significant bilateral differences
as a function of either emotional or cognitive
content. Subjects displayed a propensity for left looking
across conditions.
There was an intriguing, but nonsignificant similarity
between left LEMs and increased blood flow to subjects'
left sides in response to negative questions. However, no
clear evidence was found for hemispheric effects on LEMs
or FPV.
Results are discussed in terms of the use of automation,
the possible effects of subject stress and stimulus
development and construction. Recommendations for future
research include the gathering of evidence for the connection
of hemispheric activity and LEMs at the neurophysiological
level and the continued use of corroborative
physiological measures such as FPV. | |
