Feedback and Skill Learning

Abstract

This study was an investigation of the course of learning a specified arm movement pattern under conditions that varied as to the type and frequency of feedback information. After several days of practice, subjects performed a criterion test which was the same as the learning movement pattern, but explicit visual feedback was withdrawn.

Forty undergraduate students were divided into five groups. Each group was randomly assigned a method of learning the task. The methods of receiving information about performance were as follows: (a) concurrent visual feedback, (b) concurrent proprioceptive feedback and terminal knowledge of graphs, (c) a combination of (a) and (b), (d) concurrent visual feedback interspersed with passive watching, and (e) concurrent visual feedback at two different speeds.

The results indicated the following: (a) the most effective variable for learning the pattern was concurrent visual feedback, (b) performing the movement at a slower than normal rate was detrimental to performance on the criterion test, (c) sitting and watching was as effective a learning method as performing at two speeds, and (d) subjects in the slow-standard speed group were significantly poorer than subjects in other groups during performance of the criterion test. The other methods did not differ significantly from each other.     

Editorial Policies

Abstract

A screening test for lateral dominance was administered to 167 college women. Twenty-six showed left dominance. Of this group four were taught to bowl left-handed, six were eliminated from the study for various reasons and 16 were taught to use their preferred hand, the right. All 20 subjects preferred using their right hand. Both groups were equated as to the amount of practice and motor ability. The group using the presumably dominant left hand were significantly poorer in their bowling average than the group which, though demonstrating left dominance, were permitted to bowl with their preferred hand.     

Comparison of Seriation and Multidimensional Scaling: Two Techniques for Validating Constructs in Physical Education

Abstract

Several scaling techniques were identified as procedures that might be useful in the statistical validation of constructs in physical education. The purpose of this study was to examine solutions obtained by the techniques of seriation and multidimensional scaling, one- and two-dimensional, as varying degrees of error were introduced into specific data sets. Using a Monte Carlo model, four different sized matrices were selected to represent situations that could be applicable to research problems in physical education, such as ordering developmental sequences, course objectives, and levels of behavior in curriculum hierarchies. Kendall's tau (τ) values were computed between the ordering resulting from the matrix with no error and all other solutions for a particular matrix size in order to compare the solutions utilizing various scaling techniques, matrix sizes, and degrees of error. An analysis of variance of the 4 × 3 × 3 design of the study yielded three significant main effects of matrix size, random error, and scaling technique. Tau values served as the dependent measures with ten replications per cell. The following results were obtained: (a) the larger matrix sizes produced the most accurate results; (b) as error increased, the accuracy of all solutions decreased; (c) the technique of seriation produced slightly more accurate solutions than one- and two-dimensional multidimensional scaling.

Relationships of hip abductor strength,neuromuscular control,and hip width to femoral length ratio with peak hip adduction angle in healthy female runners

ABSTRACT

A large peak hip adduction angle during running is a risk factor for several overuse injuries in women. The purpose of this study was to determine if female runners with a large peak hip adduction angle have differences in eccentric hip abductor muscle strength, hip neuromuscular control, and/or hip width to femoral length ratio (HW:FL) compared to those with a small angle. Hip adduction during running, hip strength, hip control, and HW:FL were measured in sixty healthy female runners (1.66 ± 0.06 m; 63.2 ± 8.3 kg; 27 ± 6 years). Data from twenty runners with the largest and twenty with the smallest peak hip adduction angles were analysed. Between-group differences in hip strength, control, and HW:FL were determined using independent t-tests (p < 0.05). Variables that were significantly different between groups were entered into a regression model. Runners in both groups had similar hip strength (p = 0.90) and control (p = 0.65). HW:FL was greater in the large peak angle group (p = 0.04), but only explained a small amount of peak hip adduction angle variance for all sixty runners (R² = 0.05). Alarge peak hip adduction angle in some healthy female runners may simply be instinctive as there were no deficiencies in the strength or neuromuscular control constructs assessed.     

Perceptions of School and Aspirations of Rural Students with Learning Disabilities and Their Nondisabled Peers

This study examined the school perceptions and educational aspirations of 6,599 rural high school students, a sample that included 428 students with learning disabilities (LD). Regardless of disability status, rural high school students who had negative perceptions of school had less well‐defined postsecondary educational plans and less often aspired to complete college or pursue an advanced degree. Compared to nondisabled youth, rural students with LD were more likely to have negative perceptions of school and lower postsecondary aspirations. However, students with LD who had positive perceptions of school more often planned to pursue postsecondary education and aspired to complete college or an advanced degree. Implications for research and interventions pertaining to the educational attainment of students with LD are discussed.
