AB The planning and execution of manual actions can be influenced by concomitant processingof manual action verbs. However, this phenomenon manifests in varied ways throughoutthe literature, ranging from facilitation to interference effects. Suggestively, stimuli acrossstudies vary randomly in two potentially relevant variables: verb motility and effector quantity(i.e., the amount of movement and the number of hands implied by the word, respectively).Here we examine the role of these factors during keyboard typing, a strategic bimanual taskvalidated in previous works. Forty-one participants read and typed high and low motilityitems from four categories: bimanual, unimanual, and non-manual action verbs, as well asminimally motoric verbs. Motor planning and execution were captured by first-letter lag (thelapse between word presentation and first keystroke) and whole-word lag (the lapsebetween the first and last keystroke). We found that verb motility modulated action planningand execution, both stages being delayed by high (relative to low) motility verbs. Effectorquantity also influenced both stages, which were facilitated by bimanual verbs relative tounimanual verbs and non-manual verbs (this effect being confined to high motility items during action execution). Accordingly, motor-language coupling effects seem sensitive towords’ implied motility and number of evoked limbs. These findings refine our understandingof how semantics influences bodily movement.
