Ad. Mckenzie et Bl. Howe, THE EFFECT OF IMAGERY ON SELF-EFFICACY FOR A MOTOR SKILL, International journal of sport psychology, 28(2), 1997, pp. 196-210
A multiple-baseline-across-subjects design was used to investigate the
effect of mental imagery training on the magnitude of individuals' se
lf-efficacy for a dart throwing task. Six (n = 6) subjects were admini
stered a 15-session mental imagery training program following baseline
sessions of varying lengths. Each imagery session included a relaxati
on component, followed by specific imagery training. Subjects were the
n asked to stand, perform a one minute centering exercise, and to imag
e successful performance of the task. This war immediately followed by
the completion of a self-efficacy and imagery rating scale, and actua
l performance of the task while blindfolded. Two subjects showed that
their self-efficacy magnitude for the task had increased as a result o
f the imagery training. All subjects reported an improvement in their
overall ability to image the task as a result of the intervention. It
was concluded that imagery was able to enhance self-efficacy magnitude
for the dart throwing task in subjects who were high ability imagers,
had previous experience at throwing darts, believed in the performanc
e-enhancing capabilities of mental imagery training, and had been expo
sed to relaxation and imagery procedures prior to the study.
