Active participants explored a desktop three-dimensional computer-simulated
environment, whereas observer participants passively watched the screen. T
he ostensible task for all participants was to remember as many objects as
possible that were encountered during the course of exploration. In a test,
all participants were asked to indicate the direction of test locations fr
om a position where these were not directly visible. Contrary to the hypoth
esis of superior orientation performance in the active group, the error sco
res for the two groups were found to be statistically equivalent. There wer
e no significant differences between the scores of the active and passive g
roups on three tests of memory for objects. The results suggest that the fa
ilure to find a beneficial effect on orientation of active exploration in a
virtual environment is not due to high levels of attention to the spatial
aspect of the task in the passive condition.
