Abstract
Social stimuli, like faces (Kanwisher, McDermott, & Chun, 1997) or bodies (Downing, Jiang, Shuman, & Kanwisher, 2001), engage specific areas within the visual cortex. Behavioural research reveals an attentional bias to these same stimuli (Ro, Friggel, & Lavie, 2007). The current study examined whether there is an attentional bias towards hands, and whether such a bias is distinct from any bias towards human bodies. In a two-alternative, forced-choice dot-probe task, participants saw two side-by-side pictures for 500 ms. A probe dot then appeared on either side and participants indicated where the dot appeared. Participants were significantly faster to respond when the probe location coincided with the location of pictures of bodies, hands, or feet, compared to dogs, starfish, hand tools, toaster ovens, inverted hands, or inverted bodies. Results suggest an attentional bias to bodies and body parts but found no evidence of a difference in attentional advantage of hands over bodies or feet.
