In Experiment 1, only orthographically projected plws were presented and subjective responses on the perceived in-depth orientation were recorded.
The size of the effect of looming sound on the perceived in-depth orientation found in Experiment 1 may thus be an underestimation.
Schouten and Verfaillie [34] recently developed a technique to gradually manipulate the perceived in-depth orientation of plws with perspective cues.
The goal of the present study was to test whether looming and receding sounds affect the perceived in-depth orientation of depth-ambiguous plws.
The goal of the present study was to test whether the perceived in-depth orientation of depth-ambiguous point-light walkers (plws) is affected by the presentation of looming or receding sounds synchronized with the footsteps.
First, under the hypothesis that looming sounds (green bars) affect the perceived in-depth orientation of orthographic plws, relative to trials without sound (blue bars), we should observe an increase in performance for trials containing receding plws and a decrease in performance for trials containing looming plws.
Alternatively, if looming and receding sounds had an effect such that the perceived in-depth orientation was modified in the direction suggested by the sound, proportions of FTV responses should be higher in the looming condition and lower in the receding condition, compared to the no-sound condition.
A possible explanation of the absence of an effect of receding sounds in Experiment 2 is that receding sounds, under particular circumstances, affect the perceived in-depth orientation of plws but that in Experiment 2 it was easier to ignore receding sounds than to ignore looming sounds.
Second, under the hypothesis that receding sounds (red bars) affect the perceived in-depth orientation of orthographic plws, relative to trials without sound (blue bars) we should observe a decrease in performance for trials containing receding walkers and an increase in performance for trials containing looming walkers.
The statement suggests that Dr. Jiang acknowledged the threat that the party perceived in the student-led protests.
The internal clock remains steady, regardless of the emotion perceived in the other.
