Effect of emotions on temporal attention.

Abstract

Emotions play a significant role in guiding everyday actions and strongly interact with attention. The processing of emotional information over time and the influence of attention on such processing has been studied through the phenomenon of attentional blink using rapid serial visual presentations (RSVP) tasks. This chapter discusses the interaction between temporal attention and the type of emotional information (words, scenes, and facial expressions) presented during or before the RSVP stream. The findings show that the affective content and the arousal value of the emotional stimuli presented as first target, second target, or both affects the magnitude and the duration of the blink window. In addition, modulation of emotional context or presentation of emotions in the RSVP stream as task irrelevant distractors also influenced attentional blink. Further, this chapter discusses different models and theories of attentional blink and attempts to explain the emotional effects. The chapter concludes with possible scope for future studies.
