The Effects of Body Movements on Attitudes
I. Motor actions and emotion
- Strack, Martin, & Stepper (1988):
Asked participants to look at different drawings while holding a pen in their mouth
Gripping with teeth (smile) vs. gripping with lips (frown)
Those in the smile condition found the drawings significantly more amusing
II. Motor actions and attitude
- Wells & Petty (1980):
Listen to an editorial through headphones, believed they were evaluating the quality
of the headphones
Nod their head (jogging quality) or shake their heads (cycling quality)
Nodders agreed more than the shakers
- Cacioppo, Priester, & Berntson (1993):
Seated at a desk, asked to say whether they liked or disliked 24 different Chinese
ideographs
Indicate attitude while lifting their palms up against the bottom of the table
(flexion) vs. pressing their palms down against the top of the table (extension)
Ideographs viewed during arm flexion were subsequently liked significantly more
Did not rate the two movements as different in enjoyment
How do Motor Actions Affect Attitude?
- ELM: bodily actions can function as a cue, an argument, or a factor affecting the amount
of issue-relevant thinking and the amount of bias in these thoughts; can affect the
confidence in these thoughts (congruent with Meta-Cognition Model)
Lack of motivation and ability to think about a persuasive message bodily actions
as a cue
Some motivation bodily actions determines how much we think about the
message strong arguments more impactful
Reclining participants thought more than standing participants
- Briñol and Petty (2008): variables can also affect our confidence in the thoughts that we
have after reading a message
Occur when people enact behaviour after receiving information and forming
cognitive responses to it
Behaviour affect the confidence in any positive responses to strong arguments
and negative responses to weak arguments
