Effects of target speed and number of revolutions of practice on rotary pursuit performance of adult females: Measuring procedural intelligence
Year: 1988
Type: dissertation
Abstract: The present study investigates the effects of target speed and number of revolutions of practice on rotary pursuit performance of right-handed female college students (N=80) on ten derived measures.Subjects practiced at one of four target speeds (40, 50, 60, or 70 rpm) in one of tw o pre-rest practice conditions (550 revolutions or 8 min.).All subjects rested for 20 minutes and then resumed practice for 8 minutes.Results indicate major effects due to target speed.However, reducing target speed should not be conceptualized as merely making the task "easier."Data suggest this manipulation so alters the nature of the task confronting the perceptual system of the subject that rotary pursuit might better be regarded as an entirely different task at different target speeds.Manipulating the number of revolutions of practice at a given target speed significantly affected only one derived measure of rotary pursuit performance, mean total tim e-on-target during the post-rest practice.Two randomly selected groups who practiced at 70 rpm for 8 min.did not differ significantly on any of ten m easures of performance.When subjects who practiced at 70 rpm for 8 min.were divided into two groups based on pre rest performance levels, significant differences were found on several of the m easures.Implications of these findings are considered as a m easurem ent problem confronting investigators employing any visual-motor task in a study of the development of the procedural system.
