Figure 1.
Mean group dendrograms of the mental practice group (n = 13) for the golf putt.
The dendrograms refer to (a) pre-test, (b) post-test and (c) retention-test. The numbers on the x-axis relate to the BAC number, the numbers on the y-axis display Euclidean distances. The lower the link between related BACs, the lower is the Euclidean distance. The horizontal dotted line marks dcrit for a given α-level (dcrit = 3.41; α = .05): links between BACs above this line are considered not related; horizontal grey lines on the bottom mark clusters. BACs: (1) shoulders parallel to target line, (2) align club face square to target line, (3) grip check, (4) look to the hole, (5) rotate shoulders away from the ball, (6) keep arms-shoulder triangle, (7) smooth transition, (8) rotate shoulders towards the ball, (9) accelerate club, (10) impact with the ball, (11) club face square to target line at impact, (12) follow-through, (13) rotate shoulders through the ball, (14) decelerate club, (15) direct clubhead to planned position, and (16) look to the outcome.

Mean group dendrograms of the combined practice group (n = 13) for the golf putt.
The dendrograms refer to (a) pre-test, (b) post-test and (c) retention-test (α = 0.05; dkrit = 3.41).
Figure 3.
Mean group dendrograms of the physical practice group (n = 13) for the golf putt.
The dendrograms refer to (a) pre-test, (b) post-test and (c) retention-test (α = 0.05; dkrit = 3.41).

Mean group dendrograms of the control group (n = 13) for the golf putt.
The dendrograms refer to (a) pre-test, (b) post-test and (c) retention-test (α = 0.05; dkrit = 3.41).

Mean radial error (i.e., accuracy) in cm from pre-test to post- and retention-test. The different lines relate to the different groups. Error bars represent standard errors.

Bivariate variable error (i.e., consistency) in cm from pre-test to post- and retention-test. The different lines relate to the different groups. Error bars represent standard errors.
