The Effects Of Cognitive And Perceptual Load

The effect of cognitive and perceptual load, cued attentional focus and stimulus rarity on attentional capture by abrupt-onset stimuli.

ABSTRACT:
Abrupt-onset stimuli have been observed to exhibit significant attentional capture effects, however the automaticity of this process has been questioned in recent literature (Yantis & Jonides, 1990; Neo & Chua, 2006). The current study examined the effect of pre-focused attention and stimulus frequency on attentional capture by abrupt-onset stimuli, in order to further explore the automaticity of this process. It was observed that abrupt-onset stimuli are effective in capturing attention, but the strength of this effect is greatly determined by other variables, including attentional focus and stimulus rarity; and in particular, cognitive and perceptual load (Minamoto et al., 2015; Lavie & Tsal, 1994). It was concluded that attentional capture by abrupt-onset stimuli is not an automatic process as it fails to meet the load-insensitivity and intentionality criteria (Yantis & Jonides, 1990). These findings lay a foundation for further attentional research, an important factor of educational psychology.

Attention is a cognitive phenomenon that describes an individual’s ability to focus their awareness on salient external stimuli (Rensink et al., 1997). Automatic attentional capture, i.e.
