Adults with autistic traits (high-autism quotient [AQ] scores) and matched controls (low-AQ) observed
intentional hand actions, and pictures of manipulable and non-manipulable objects. The high-AQ group compared to
the control group, showed anomalous modulation of the electroencephalographic motoric rhythms (mu and beta) while
observing familiar goal-directed actions, confirming an impairment of their mirror neuron system. Also, their brain
rhythms were anomalous when they watched manipulable objects, which suggest a dysfunction in their relation with
objects (affordance system).
