Age Differences on a Coincident Anticipation Task: "Preferred" Movement Speed and Response Strategy Use.
Williams, Kathleen
An investigation examined the use of "preferred speeds" by young children in their response to a timing task. Three groups of boys, 5, 7, and 9 years old, made a simple horizontal arm movement that would end with contacting a microswitch at the same time a light reached the end of the runway. One stimulus traveled at the individual's preferred speed (predetermined during an initial session); four others were selected in .8 mph increments from that baseline preferred speed (two faster, two slower). The hypothesis was that subjects of all ages would perform most accurately when stimuli traveled at their preferred speed. Young children would be inaccurate at all other speeds, while older subjects would modify their response in relation to stimuli traveling at slow to intermediate speeds. As hypothesized, the 5-year olds responded accurately when the light speed matched their preferred speed. At other velocities, they either moved too quickly or too slowly. Seven- and 9-year old children were able to match their arm speeds to stimulus velocities up to and including their preferred speed. At higher velocities, they moved too slowly. Observation suggested that most children were attempting to use a rudimentary response strategy by 7 years of age. (Author/JM)
