TL;DR: In this paper, the effect of low versus high approach-motivated positive affect on attentional blink was explored, and the results showed that both low and high positive affect improved the performance of attentional blinking.
Abstract: Attentional blink reflects the limitation of attention resource over time. This is the first study to explore the effect of low versus high approach-motivated positive affect on attentional blink. We used food and humor videos to induce high approach-motivated positive affect (desire) and low approach-motivated positive affect (amusement) separately. Subjects were required to complete classic attentional blink tasks. The performance of attentional blink was indicated by the accuracy of T2 when T1 was correct. Results showed both low and high approach-motivated positive affect improved the performance attetional blink, and this effect was bigger in low approach-motivated positive affect than high. Further analysis revealed that low approach-motivated positive affect improved the accuracy of T2 when T1 was correct on lag4 and lag5, however, high approach-mo- tivated positive affect improved the accuracy of T2 when T1 was correct on lag1 and lag2, which may indicate different mechanisms of effect of low versus high approach-motivation on attention- al blink. In the end, we summarized the deficiencies of this research and proposed future direc- tions.

TL;DR: The results of the first study suggest that an attentional blink affects the whole visual processing system and speak for the existence of a unified attentional system operating comprehensively within the visual system.
Abstract: We are constantly exposed to an abundance of visual information in our environment. Selective visual attention allows us to behave in a goal-directed and flexible manner in this crowded environment. However, we still do not understand the complex neuronal networks underlying the ability to attend and filter out selected information. This thesis contains four studies investigating the networks of selective visual attention in the human and non-human primate. The prefrontal area FEF has been suggested to play a fundamental role in guiding attentional modulation in visual areas. However, the methods used until now were unable to distinguish between direct and indirect effects of the FEF on visual areas. We provide histological evidence that the method of optogenetics can be used to target the fronto-visual and fronto-parietal network and its long-range axonal projections. Based on these results, we inhibited the direct connection of the FEF to visual area MT in one monkey performing a visual spatial attention task. By using optogenetics, we show that the modulation that the FEF exerts on visual area MT during attention results at least partly from a direct input from the FEF. In two psychophysics projects, we investigated the phenomenon of the attentional blink for stimuli processed in the dorsal visual pathway. The attentional blink has so far primarily been studied for stimuli processed in the ventral visual pathway. The results of our first study suggest that an attentional blink affects the whole visual processing system and speak for the existence of a unified attentional system operating comprehensively within the visual system. In the second study, we measured pupil size as a measure for internal cognitive processes in addition to behavioral performance. We show that pupil size can reflect different parameters of the task and could be related to the activity of the locus coeruleus.
