This page contains demos of the study “Causal actions enhance percpetion of continuous body movements“. You need Quick Time player and QT browser plugins to view the movies.
Two-agent videos (Exp 1)
Video 1:
The two actors are demonstrating a causal interaction and the catcher’s limb movements are presented in the short-SOA condition. Participants tend to perceive smooth motion of the cacher.
Video 2:
The two actors are demonstrating a non-causal interaction and the catcher’s limb movements are presented in the short-SOA condition. Participants tend to perceive relatively less smooth motion of the cacher.
Video 3:
The two actors are demonstrating a causal interaction and the catcher’s limb movements are presented in the long-SOA condition. Participants tend to perceive smooth motion of the cacher.
Video 4:
The two actors are demonstrating a non-causal interaction and the catcher’s limb movements are presented in the long-SOA condition. Participants tend to perceive sudden motion of the cacher.
Two-agent with occluder videos (Exp 2)
Video 1:
The two actors are demonstrating a causal interaction and the catcher’s limb movements are presented in the short-SOA condition. Participants tend to perceive smooth motion of the cacher.
Video 2:
The two actors are demonstrating a non-causal interaction and the catcher’s limb movements are presented in the short-SOA condition. Participants tend to perceive relatively less smooth motion of the cacher.
Video 3:
The two actors are demonstrating a causal interaction and the catcher’s limb movements are presented in the long-SOA condition. Participants tend to perceive smooth motion of the cacher.
Video 4:
The two actors are demonstrating a non-causal interaction and the catcher’s limb movements are presented in the long-SOA condition. Participants tend to perceive sudden motion of the cacher.
Single-actor videos (Exp 3)
Video 1:
The actor is demonstrating a causal interaction with the ball and the person’s limb movements are prsented in the short-SOA condition. Participants tend to perceive smooth motion of the cacher.
Video 2:
The actor is demonstrating a non-causal interaction with the ball and the person’s limb movements are presented in the short-SOA condition. Participants tend to perceive relatively less smooth motion of the cacher.
Video 3:
The actor is demonstrating a causal interaction with the ball and the person’s limb movements are presented in the long-SOA condition. Participants tend to perceive smooth motion of the cacher.
Video 4:
The actor is demonstrating a non-causal interaction with the ball and the person’s limb movements are presented in the long-SOA condition. Participants tend to perceive sudden motion of the cacher.
