Planning not to do something: Does intending not to do something activate associated sensory consequences?

Area of Science:

• Cognitive Neuroscience
• Neuroscience

Background:

• Ideomotor theory posits that voluntary actions become associated with their sensory consequences.
• Previous research has primarily focused on the association between executed actions and their effects.

Purpose of the Study:

• To investigate the neural underpinnings of ideomotor theory using functional magnetic resonance imaging (fMRI).
• To examine whether sensory effects can become associated with the voluntary omission of an action.

Main Methods:

• Participants underwent a training phase where decisions to act or not act were paired with specific auditory effect tones.
• In the test phase, participants performed actions or nonactions without effect tones, while brain activity was monitored using fMRI.
• Behavioral responses and neural activity in the auditory cortex were analyzed.

Main Results:

• Increased activity in the auditory cortex was observed for self-chosen actions and nonactions that were previously associated with an effect tone.
• Neural binding effects were found for stimulus-cued actions but not for stimulus-cued nonactions.
• fMRI data demonstrated that effect tones can become associated with intentionally not acting.

Conclusions:

• The findings provide neural evidence supporting ideomotor theory by confirming the association between actions and their sensory consequences.
• The study demonstrates, at a neural level, that sensory effects can be associated with the voluntary omission of an action.
• This supports the concept of neural binding between intentional nonaction and its environmental effects.
