The development of perceptual motor sequencing ability

The purposes of this study were (a) to investigate the possibility that short-term memory may be a limiting factor in the development of perceptual-motor sequencing ability, (b) to determine whether sex differences exist in sequencing ability, (c) to determine whether organized information facilitates serial recall, and (d) to ascertain whether the recall of serial perceptual-motor responses results in a bow-shaped serial-position curve. A 2 × 2 × 3 factorial design was used to analyze the independent variables of age, sex, and pattern organization. Further, an age × serial position ANOVA was performed to investigate the serial-position curve. Serial recall improved with age; however young children experienced difficulty in recalling a complex task. The poor recall performance of 5-yr.-old children was discussed in terms of the possibility that young children fail to use labeling strategies to facilitate recall. No sex differences were found. A primacy effect was obtained on the complex task.
