Abstract or Summary
  • In rapid serial visual presentation, identification of the second of two targets is impaired when it closely follows the first target. This attentional blink (AB) effect suggests limited capacity in processing successive visual stimuli in working memory. Awh et al. (2004) found that face identity Target 2 was immune to the AB when performed together with a digit Target 1. They proposed a mul$-channel model in which digit processing utilizes a featural channel, leaving the configural channel available for face processing. The present study examined whether the processing of facial emotion (via the configural channel) facilitates the bypassing of capacity limitations for a word (via the featural channel), producing no AB effects. We further examined whether AB effects will increase when Target-2 difficulty is increased (requiring more processing resources).
