Abstract

In order to overcome our limited amount of attentional resources, particular items in space must be selected as targets. For infants, attentional resources are even more limited. Models of attention have proposed that resources are restricted to particular spatial locations, enhancing processing at these locations. Evidence for selection due to spatial attention has been provided by studies that use a spatial cueing paradigm, in which attending to the particular location indicated by a preceding cue results in faster and more accurate selection of, and eye movements to, items presented at that location compared to when no cue is presented. Whether infants exhibit similar spatial attention and target selection mechanisms has yet to examined. To this end, in the current study, 3-month-old infants were presented with either no cue or with a 150 msec cue to either the right or left of fixation indicating the subsequent location of the target to which they should make an eye movement. Then, either one stimulus or two stimuli were presented at 5° from fixation and the latency of infants’ eye movements was measured to the one of the stimuli or to the cued target. Preliminary results have indicated that, consistent to findings with adults, presentation of the spatial cue resulted in a facilitation of target selection as exhibited by a decrease in infants’ eye movement latency. Infants’ eye movement latencies, however, were much slower than typically found in studies with adults. This finding suggests that the mechanisms responsible for the allocation of spatial attention in guiding target selection is functioning in early infancy. Yet, these mechanisms require further development to reach full efficacy, though the full extent of the developmental deficiencies remains to be determined.
