Table 1.
Means and standard deviation for visual fixation in seconds for baseline (first two habituation trials), final two habituation trials, posthabituation (two no-change trials just following habituation reflecting final interest level), test trials, processing time (total number of seconds fixating the habituation events), and visual recovery (difference between test trial and posthabituation fixation) as a function of the presence vs. absence of intersensory redundancy (bimodal, redundant vs. unimodal, nonredundant) and task difficulty (low, moderate, high).
