Abstract
The purpose of this research was to investigate the effect of differential training and contextual interference on learning and mental representation of the golf shot.
. Fifty female students with an age range of 20-35, were purposefully selected. Participants were randomly divided into five groups: random differential learning, blocked differential learning, random contextual interference, blocked contextual interference, and control. Standard golf balls and sticks, circular targets with a diameter of 11 cm on a grass field with dimensions of 9 x 4 meters, and mental representation measurement software were used to carry out the task. In the pre-test, the subjects performed the task of measuring mental representation and took 15 golf shots from a distance of 3 meters. During the acquisition phase of 12 blocks, participants made 15 attempts in accordance with the educational instructions related to their groups. 24 hours after the acquisition session, they participated in a memory test under similar conditions to the pre-test
.Results
The results showed that the performance of the random differential group was significantly different from the other groups and performed weaker than them (P=0.001). In the retention test, the random differential and random contextual interference groups had higher accuracy than the blocked differential and blocked contextual interference groups (P=0.001). However, in the transfer test, the differential learning groups performed more accurately than all the groups. There was a significant change in mental representation in memory in the random differential group compared to the pre-test (P=0.001).
