Shaded bars “expert”, pale bars “naïve” responses. Cue conditions: b = clown target (blur available), d = binocular target (disparity available), p = looming dynamic target (proximal cues available), o = all cues minimised.
Asterisks denote statisticallly significant differences between expert and naïve response slopes.
