Effect of the bottom - up salience in the rapid serial visual presentation paradigm

S Shih

The attentional blink (AB) paradigm was used to examine the effect of bottom - up salience (BUS) by varying the task relevance of BUS and the temporal location of a colour singleton distractor (SD) in relation to that of the second (T2) of the two targets in a rapid serial visual presentation (RSVP) stream. The T2 was never a singleton. Despite the variation in the certainty regarding the BUS of the first target (T1), the number of colour singletons in a stream, and the colour congruence between the singleton T1 and the SD, the results were consistent across the three experiments. Independent of the onset asynchrony between T1 and T2, the SD displayed prior to the T2 increased the identification accuracy of T2 without affecting the AB effect per se. The results were consistent with the proposal that the BUS in RSVP affects the kind of attention gating (automatic versus controlled) that transfers the preliminary representations in the perceptual buffer into working memory (Shih, 2000 Perception & Psychophysics 62 1348 - 1355). The findings are interpreted in terms of the attention-cascade model that incorporates the AB models and the strength model of spatial visual attention (Shih and Sperling, 2002 Psychological Review 100 260 - 305).
