IPA: //ˌaɪdiˈmoʊtər//
KK: /ˈaɪdiˌmoʊtər/
Relating to movements that happen without conscious control, often triggered by thoughts or ideas instead of physical sensations.
The ideomotor response can be observed when a person moves their hand without realizing it, simply because they are thinking about the action.
Ideomotor is formed from "ideo-" (from Greek "idea", meaning form or concept) and "motor" (from Latin "motor", meaning mover). The term refers to movements that are initiated by the thought of the action rather than by conscious intention.
Think of 'idea' as a thought that leads to a 'movement' ('motor') — that's how ideomotor actions happen.
