Effects of observer's experience and skill level on learning and performance in motor skill modeling

Downey, Margaret J. January 1991 (has links)
Expertise effects on response acquisition (learning) and performance reproduction (performance) (Bandura, 1986) in dance observational learning were investigated. Over an acquisition period, forty university students with varied movement backgrounds observed dance demonstrations, arranged still photos to represent the dances, and performed each dance. Learning was assessed via a pictorial-resequencing task. Dance performance accuracy and quality were evaluated via detailed analyses of videotaped performances. Results indicated that dance experts learn more and perform better than novices (p $<$.05) in a modeling situation, and learning and performance scores are positively correlated at a moderate level. Entry-level dance skill is the best present indicator of success in dance observational learning. Elementary instruction can improve beginner dancers' observational learning ability. The findings support Bandura's social cognitive theory of modeling (1986), extend the knowledge base related to the effects of expertise in motor skill acquisition, and have implications for dance and other motor skill educators.

Incidence de l'imagerie motrice sur les apprentissages moteurs/ Impact of motor imagery on motor learning

Delbecque, Laure A S 23 May 2008 (has links)
The topic of this work is motor imagery. Through 7 different studies, the process and proprieties of motor imagery and its impact on motor learning were assessed. It was found that this cognitive activity is closely linked to the motor system. This characteristic underlies the positive effects of motor imagery on motor learning. This can have many practical applications in the domain of sport and motor rehabilitation.

The Design, Fabrication, and Modeling of a Piezoelectric Linear Motor

Vaughan, Mark Edward 02 January 2002 (has links)
The focus of this research was to create a linear motor that could easily be packaged and still perform the same task of the current DC motor linear device. An incremental linear motor design was decided upon, for its flexibility in which the motor can be designed. To replace the current motor it was necessary to develop a high force, high speed incremental linear motor. To accomplish this task, piezoelectric actuators were utilized to drive the motor due their fast response times and high force capabilities. The desired overall objectives of the research is to create an incremental linear motor with the capability of moving loads up to one hundred pounds and produce a velocity well over one inch per second. To aid the design process a lumped parameter model was created to simulate the motor's performance for any design parameter. Discrepancies occurred between the model and the actual motor performance for loads above 9.1 kilograms (20 pounds). The resulting model, however, was able to produce a good approximation of the motor's performance for the unloaded and lightly loaded cases. The phase one design was limited by time constraints so a relatively low risk design was produced. The resulting incremental linear motor produced a velocity of 4.9 mm/sec (0.2 in/sec) at a drive frequency of 50 Hz. The velocity of the motor was limited by the drive frequency that the amplifiers could produce. The motor was found to produce a respectable stall load of 17 kilograms (38 pounds). The stall load of the phase one design was severely limited by clearance losses. An analysis of the motor's performance was conducted, possible improvements and future work recommendations for a phase two design are presented. / Master of Science
