From: No evidence that monkeys attribute mental states to animated shapes in the Heider–Simmel videos
Monkeys’ mean fixation duration did not significantly correlate with humans’ fixation durations or intentionality ratings (data from Klein et al.8). (a) Monkeys’ mean fixation duration (ms) for each animation as a function of the humans’ mean fixation duration reported in Klein et al.8. (b) Monkeys’ mean fixation duration (ms) for each video as a function of humans’ intentionality ratings (0–5; 0 = nondeliberate action and 5 = deliberate action with the goal of affecting the other’s mental state). Each symbol represents data from a single animation. Colors represent animation categories, and match assignments used in Figs. 1, 2 and 3.
