Pupil dilation: A fingerprint of temporal selection during the "Attentional Blink"

Pupil dilation indexes cognitive events of behavioral relevance, like the storage of informa- tion to memory and the deployment of attention.Yet, given the slow temporal response of the pupil dilation, it is not known from previous studies whether the pupil can index cog- nitive events in the short...

Attentional blink Processing bottleneck Psychological refractory period Pupil dilation Timing of attention Pupil dilation indexes cognitive events of behavioral relevance, like the storage of informa- tion to memory and the deployment of attention.Yet, given the slow temporal response of the pupil dilation, it is not known from previous studies whether the pupil can index cog- nitive events in the short time scale of ~100 ms. Here we measured the size of the pupil in the Attentional Blink (AB) experiment, a classic demonstration of attentional limitations in processing rapidly presented stimuli. In the AB, two targets embedded in a sequence have to be reported and the second stimulus is often missed if presented between 200 and 500 ms after the first. We show that pupil dilation can be used as a marker of cognitive pro- cessing in AB, revealing both the timing and amount of cognitive processing. Specifically, we found that in the time range where the AB is known to occur: (i) the pupil dilation was delayed, mimicking the pattern of response times in the Psychological Refractory Period (PRP) paradigm, (ii) the amplitude of the pupil was reduced relative to that of larger lags, even for correctly identified targets, and (iii) the amplitude of the pupil was smaller for missed than for correctly reported targets. These results support two-stage theories of the Attentional Blink where a second processing stage is delayed inside the interference regime, and indicate that the pupil dilation can be used as a marker of cognitive processing in the time scale of ~100 ms. Furthermore, given the known relation between the pupil dilation and the activity of the locus coeruleus, our results also support theories that link the serial stage to the action of a specific neuromodulator, norepinephrine. © 2012 Zylberberg, Oliva and Sigman.
