In a crowded dynamic world, temporal expectations guide our attention in time. Prior investigations have consistently demonstrated that temporal expectations speed motor behavior. We explore effects of temporal expectation on "perceptual" speed in three nonspeeded, cued recognition paradigms. Different hazard rate functions for the…

Examined the ability of 1-year olds to remember the location of nonvisible targets. Found that infants were able to associate a nonvisible target with a direct landmark and to code its distance and direction with respect to themselves or the larger framework. Difficulty of coding with indirect landmarks was associated with cognitive complexity and…

Discusses changes occurring in two-, four-, and six-month-old infants' visual attention span, through a series of experiments examining their ability to orient to peripheral visual stimuli. The results obtained were consistent with the hypothesis that infants get faster with age in shifting attention to a spatial location. (AA)
