Visual perspective-taking in complex natural scenes

Studies of visual perspective-taking have shown that adults can rapidly and accurately compute their own and other peoples’ viewpoints, but they experience difficulties when the two perspectives are inconsistent. We tested whether these egocentric (i.e. interference from one’s own perspective) and altercentric biases (i.e. interference from another person’s perspective) persist in ecologically-valid complex environments. Participants (N=150) completed a dot-probe visual perspective-taking task, in which they verified the number of discs in natural scenes containing real people, first only according to their own perspective and then judging both their own and another person’s perspective. Results showed that the other person’s perspective did not disrupt self perspective-taking judgements when the other perspective was not explicitly prompted. In contrast, egocentric and altercentric biases were found when participants were prompted to switch between self and other perspectives. These findings suggest that altercentric visual perspective-taking can be activated spontaneously in complex real-world contexts, but is subject to both top-down and bottom-up influences, including explicit prompts or salient visual stimuli.
