A

impaired organizing of motor chains

in execution and observation of actions

3
Q

how and what Exp1 Cattaneo

A

observing condition: grasp + eat vs grasp + container

measurement of mouth muscles (MH)

TD: activation in MH from reaching phase

autistic: no activity
- > lack of understanding intention?

4
Q

how and what Exp3 catteano

A

acting condition: grasp+eat vs grasp+container

TD: MH active before grasping

autistic: MH only active while bringing to mouth phase
- > lack of complete motor chain

5
Q

how and what Exp3 catteano

A

acting condition: Hand/foot movement

TD: preparatory activity observed

autistic: no preperatory activity
- > problem: chaining single motor acts to whole

6
Q

Conclusion catteano: chaining organization

A

TD: forming complete chain of single motor acts

  • > final muscle active from first element on
  • > observing: chain also competely active (understanding intention)
    autistic: failure to organize motor chain in forward fashion
  • >observing: failure to mirror motor chain leads to trouble understanding the intention in someones action
7
Q

understanding intention: 2 processes

A
  1. what is he doing? no understanding of mental state required
  2. why is he doing it? understanding of mental state required
