Resumen:
Abundant research shows that processing action verbs (e.g., applaud) modulates the execution of manual actions (e.g., object grasping). To examine such effects in the context of language-relevant actions, we designed a word typing task. Participants typed the second of two visually presented verbs, denoting motor-manual, motor-non-manual or non-motor activities. We analyzed the lapse from (i) target onset to first letter press and (ii) first to last letter press. Relative to non-motor verbs, both primes and targets denoting motor actions interfered with typing speed. First-letter lag was greater when primes denoted manual actions and when targets denoted non-manual actions. Motor primes, but not motor targets, also interfered with whole-word typing. However, typing was facilitated when the target was primed by a semantically congruent verb. These results suggest that motor-semantic integration processes evince different dynamics during motor planning vs. motor execution.
