Abstract: Four case studies of time-series motor performances were designed to examine relationships among serial recall, visual and kinesthetic perceptual attributes, and spatial complexity. The task included four nine-element serial sequences and two tossing sequences. Subjects performed a series of movement patterns that included walking, simple hand motions, ducking under or stepping over obstacles, stacking blocks of differing colors, and walking in geometrically shaped floor patterns. Selected perceptual demand characteristics were structured into the four serial sequences, i. e., high-visual (HV) versus low-visual (LV) attributes and a four- versus nine-destination spatial environment. Subjects first completed two perceptual tests, The Rod-and-Frame Test and the Space relations subtest of the Differential Aptitude Test. Fifteen trials were conducted over three weeks. Performances were timed and coded by trained observers. Timed data included total time for each trial and partial times for each element within the trial. Two interventions changed element order within sequences and sequence order within task.
