Voluntary action affects perception of bistable motion display

Area of Science:

• Cognitive Psychology
• Neuroscience
• Visual Perception

Background:

• Action can influence how we perceive visual motion.
• Common coding frameworks suggest shared representations for action and perception.
• The role of movement representation and action goals in this interaction needs further clarification.

Purpose of the Study:

• To investigate if movement representation and distal action goals affect biased motion perception.
• To determine how action goals link movement and perceptual representations.

Main Methods:

• Utilized a stream-bounce display where participants controlled disk movement via mouse.
• Manipulated the consistency of mouse and disk directional motion.
• Conducted experiments to rule out attention as a confounding factor.

Main Results:

• Mouse movement biased perceived motion towards the 'stream' when mouse and disk directions were consistent.
• This bias was absent when mouse and disk directions were orthogonal.
• The action goal of controlling the disks was critical for the biased perception.

Conclusions:

• Feature matching in action-perception interaction occurs at the movement representation level.
• Action goals are crucial for integrating movement and perceptual representations.
• This research provides insight into the mechanisms of action-perception coupling.
