Sensorimotor Learning Modulates Automatic Imitation in Visual Speech
نویسندگان
چکیده
People automatically imitate observed actions, including speech. Automatic Imitation (AI) is linked to observationexecution associations in the mirror neuron system (MNS). AI is measured using interference tasks, in which prompts (say ”ba” or ”da”) are paired with congruent or incongruent distracters (video of someone saying ”ba” or ”da”). Faster responses for congruent than for incongruent prompt-distracter pairings signal AI. Observation-execution associations for speech actions are thought to be inflexible, unlike associations for manual actions, which have been shown to be flexible. We trained participants to reinforce or abolish their AI response by providing them with compatible (say ”ba” for a video of someone saying ”ba”) or incompatible training (say ”ba” for a video of ”da”). After training, the AI response was reduced for participants who received incompatible training, thus showing that the MNS for speech actions is also flexible and subject to experience, like the MNS for manual actions.

The associative sequence learning model proposes that the development of the mirror system depends on the same mechanisms of associative learning that mediate Pavlovian and instrumental conditioning. To test this model, two experiments used the reduction of automatic imitation through incompatible sensorimotor training to assess whether mirror system plasticity is sensitive to contingency (i.e....

Associative (not Hebbian) learning and the mirror neuron system.
The associative sequence learning (ASL) hypothesis suggests that sensorimotor experience plays an inductive role in the development of the mirror neuron system, and that it can play this crucial role because its effects are mediated by learning that is sensitive to both contingency and contiguity. The Hebbian hypothesis proposes that sensorimotor experience plays a facilitative role, and that i...

متن کاملFunctional brain outcomes of L2 speech learning emerge during sensorimotor transformation
Sensorimotor transformation (ST) may be a critical process in mapping perceived speech input onto non-native (L2) phonemes, in support of subsequent speech production. Yet, little is known concerning the role of ST with respect to L2 speech, particularly where learned L2 phones (e.g., vowels) must be produced in more complex lexical contexts (e.g., multi-syllabic words). Here, we charted the be...
