Abstract
Targets embedded within three-dimensional stimuli had lower identification thresholds than did targets embedded within two-dimensional stimuli. This finding extends the object-superiority effect to include duration thresholds for identification. The pattern of identification errors supports previous findings that structurally relevant targets are harder to identify than nonstructurally relevant targets.
