From: No evidence that monkeys attribute mental states to animated shapes in the Heider–Simmel videos
Monkeys did not show longer fixations for ToM videos. (a) Monkeys’ fixation durations as a function of animation category. Each thick horizontal line is the group mean fixation duration and each symbol represents an individual monkey’s mean fixation duration with ± 95% CI (ms). Abbreviations: ToM, Theory of Mind; GoalDir, Goal Directed; Rand, Random. (b) For comparison, humans’ fixation durations (± 95% CI) and intentionality ratings (± SD) as a function of category. Adapted from Klein et al.8. (c) Peak visual motion, left, and standard deviation in visual motion, right, of the animations as a function of category. Visual motion was calculated as in39.
