Abstract
Forty first-grade children performed 25 lever-pulling responses, with measures being taken on each trial of starting time, movement time, and response amplitude (force exerted at the termination of the response chain). For each S, Pearson r values were computed relating starting speed and movement speed (reciprocals of the respective time values) to response amplitude across trials (excluding the first). The results provided virtually no evidence for a relationship between starting speed and amplitude (r= +. 058). In contrast, a rather substantial relationship between movement speed and amplitude was revealed (r = +.511). Implications for lever studies employing children asSs are discussed.
