The attentional blink and lag 1 sparing are nonspatial.
The attentional blink (AB) refers to the finding that the perception of the second of two targets (T2) is impaired when presented in close temporal proximity to the first target (T1). An exception to this deficit occurs when T2 immediately follows T1, an effect referred to as lag 1 sparing. So far, it has been unclear whether the AB is location specific or nonspatial in nature. Most demonstrati...
متن کاملDoes failure to mask T1 cause lag-1 sparing in the attentional blink?
The attentional blink (AB) effect demonstrates that when participants are instructed to report two targets presented in a rapid visual stimuli stream, the second target (T2) is often unable to be reported correctly if presented 200-500 msec after the onset of the first target (T1). However, if T2 is presented immediately after T1, in the conventional lag-1 position (100-msec stimulus onset asyn...
متن کاملThe Attentional Blink at 20 items/sec, Model Prediction and Empirical Validation of Lag-2 Sparing
The Attentional Blink (AB) paradigm uses a Rapid Serial Visual Presentation (RSVP) stream, with two targets (denoted T1 and T2). There is a period of approximately 500 msec during which processing of T1 seems to impair the ability to detect and report T2 (Raymond, Shapiro and Arnell 1992). This suggests that the deployment of attention to processing T1 has a temporal window of a little over hal...
متن کاملLag-1 sparing in the attentional blink: benefits and costs of integrating two events into a single episode.
When people monitor a visual stream of rapidly presented stimuli for two targets (T1 and T2), they often miss T2 if it falls into a time window of about half a second after T1 onset--the attentional blink. However, if T2 immediately follows T1, performance is often reported being as good as that at long lags--the so-called Lag-1 sparing effect. Two experiments investigated the mechanisms underl...
متن کاملThe attentional blink provides episodic distinctiveness: sparing at a cost.
The attentional blink (J. E. Raymond, K. L. Shapiro, & K. M. Arnell, 1992) refers to an apparent gap in perception observed when a second target follows a first within several hundred milliseconds. Theoretical and computational work have provided explanations for early sets of blink data, but more recent data have challenged these accounts by showing that the blink is attenuated when subjects e...
