Casual Actions Demos

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.
