A dual task procedure combined with rapid serial visual presentation to test attentional blink for nontargets.
When viewers search for targets in a rapid serial visual presentation (RSVP) stream, if two targets are presented within about 500 msec of each other, the first target may be easy to spot but the second is likely to be missed. This phenomenon of attentional blink (AB) has been widely studied to probe the temporal capacity of attention for detecting visual targets. However, with the typical proc...
متن کاملA Connexionist Model of the Attentional Blink Effect During a Rapid Serial Visual Presentation Task
We introduce a connectionist model that reproduces the attentional blink effect during a rapid serial visual presentation task. The model is composed of two layers, a competitive one that acts as an identification layer and a recurrent one that acts like short term memory where the main mechanisms is the presence of an inhibition gate and a neural fatigue. Simulations show that the model genera...
متن کاملAn attentional blink for nontargets?
In a typical attentional blink experiment, viewers try to detect two target items among distractors in a Rapid Serial Visual Presentation (RSVP): processing of the first target impairs participants' ability to recall a subsequent target at short stimulus onset asynchronies (SOAs). However, little is known about whether target detection interferes with memory for nontarget items. To answer this ...
متن کاملEndogenous and Rapid Serial Visual Presentation-induced Alpha Band Oscillations in the Attentional Blink
The attentional blink (AB) is a deficit in conscious perception of the second of two targets if it follows the first within 200-500 msec. The AB phenomenon has been linked to pre-target oscillatory alpha activity. However, this is based on paradigms that use a rapid serial visual presentation (RSVP) stimulus stream in which the targets are embedded. This distracter stream is usually presented a...
متن کاملPriming T2 in a visual and auditory attentional blink task.
Participants performed an attentional blink (AB) task including digits as targets and letters as distractors within the visual and auditory domains. Prior to the rapid serial visual presentation, a visual or auditory prime was presented in the form of a digit that was identical to the second target (T2) on 50% of the trials. In addition to the "classic" AB effect, an overall drop in performance...
