Abstract
The crossmodal congruency effect (CCE) is augmented when viewing an image of a hand compared to an object. It is unclear if this contextual effect extends to a non-spatial CCE. Here, participants discriminated the number of tactile vibrations delivered to the hand whilst ignoring visual distractors on images of their own or another's hand or an object. The CCE was not modulated by stimulus context. Viewing one's hand from a third person perspective increased errors relative to viewing an object (Experiment 1). Errors were reduced when viewing hands, from first or third person perspectives, with additional identity markers (Experiments 2 and 3). Our results suggest no effect of context on the non-spatial CCE and that differences in task performance between hand and object images depend on their visual properties. These findings are discussed in light of the relationship between body representation and perception of body-centred stimuli in the temporal domain.
