title: Lateral differences in visual inspection time? The role of apparent motion cues.
abstract: There are a number of reports of a left hemisphere advantage for visual inspection time, but some investigators employing slightly different methodologies have failed to replicate the effect. The present experiment was an attempt to identify one of the factors that could have lead to these discrepant findings: The role of apparent motion cues. In Experiment 1, a lateralized version of the inspection time task was administered via a computer monitor wherein the pi stimulus was masked with a figure vulnerable to apparent motion cues. With this mask, a strong left hemisphere advantage was observed. In Experiments 2 and 3, the test was administered on a tachistoscope or computer monitor, but in both cases the stimulus was masked with a pattern "forest" mask. Under these conditions, there was no lateral difference. This result implies that the left hemisphere advantage for inspection time relies on apparent motion cues.
