Considerable effort has been made in recent years to unravel the mechanisms by which motivational and affective processes impact on behaviour and reasoning. Recent research shows that attentional processing is strongly influenced by motivational states, such as appetite. However, little has been done to investigate how affective processes influence attentional selection with naturally occurring stimuli, which is motivationally arousing. This study utilised an adapted version of Piech et al’s (2010) emotional blink of attention (EBA) paradigm by using affective priming to investigate to effect of positive affect on attentional capture. Participants (n = 30) were required to detect targets appearing in a rapid stream of visually presented stimuli, after different types of distractors irrelevant to the task. Findings show that food stimuli were captured to a greater extent following priming of positive affect within the visual streams. The study demonstrates that EBA’s may be manipulated to alter affective state and measure its influence on motivationally arousing stimuli, though the opposite may also be possible.
