Age-Related Changes in Temporal Allocation of Visual Attention: Evidence from the Rapid Serial Visual Presentation (RSVP) Paradigm

The present study explored the temporal allocation of attention in groups of 8-year-old children, 10-year-old children, and adults performing a rapid serial visual presentation task. In a dual-condition task, participants had to detect a briefly presented target (T2) after identifying an initial target (T1) embedded in a random series of distractors. A single-condition control task required participants to detect T2 without first identifying T1. The attentional blink (AB) reflects impairments in T2 detection due to the previous identification of T1. Although the "amplitude" of the AB (difference in T2 detection performance between the single task and the dual task) was found to be similar across age groups, its temporal expression (as a function of the T1-T2 lag) differed across age groups. Our results revealed age-related changes a) in the duration of the first lag(s) "sparing" effect (longer in the younger age groups), b) in the peak position of the AB (temporal displacement toward later lags in the younger age groups), and c) in the width of the AB (T2 impairments occurring for T1-T2 intervals of 400 ms and 500 ms in 8-year-old children, 300 ms in 10-year-old children, and 200 ms and 300 ms in adults). We discuss these differences in terms of changes in the efficiency of perceptual selection and inhibitory processes (attentional gating mechanisms) during development.
