We have argued elsewhere (e.g., to come to mind in the prospective fluency task for older Freeman & Ellis, in press-a) that there may be similarities adults than for young adults. There was no apparent between the advantage for to-be-enacted laboratory-age difference in the inaccessibility (or inhibition) of based actions and the advantage that is frequently already completed intentions, however, with both age observed for verbally presented action words that have groups demonstrating evidence of an intention-been enacted during encoding (the subject-performed completion effect.
