ERP Evidence for the Effects of Anthropomorphic Icons on Attention and Perceptual Decision Making

Abstract

Prior neuro ergonomic studies have shown that anthropomorphic app icons produce a more attractive attention effect. In this study, we investigate whether the attention effect of anthropomorphic icons influences the perceptual decision making process and whether the behavior performance changes with different cue durations. The attentional effects of anthropomorphic icons elicited larger N250 amplitudes. For the time course of attention effect, the results showed that the response time in the 500 ms stimulus duration is significantly faster than 250 ms. The speed of information accumulation explains the attention effects of anthropomorphic icons, as in the anthropomorphic icon cues, increased N250 amplitude was only associated with higher drift rates. These results contribute to research on the spatial attention effect of anthropomorphic icons and can be demonstrated by N250 amplitude and information accumulation speed.
