Bs. Lerner et al., THE EFFECTS OF GOAL-SETTING AND IMAGERY TRAINING-PROGRAMS ON THE FREE-THROW PERFORMANCE OF FEMALE COLLEGIATE BASKETBALL PLAYERS, The Sport psychologist, 10(4), 1996, pp. 382-397
The purposes of this study were to investigate the effects of goal-set
ting and imagery programs, as well as a combined goal-setting and imag
ery training program, on the free-throw performance among female colle
giate basketball players over the course of an entire season. A multip
le-baseline, single-subject A-B-A design was employed in which partici
pants were randomly assigned to one of three interventions: (a) goal-s
etting (n = 4), (b) imagery (n = 4), or jc) goal-setting and imagery (
n = 4). Free-throw data were collected during practice sessions. Data
were examined by way of changes in mean, level, trend, latency, and va
riability between baseline and intervention, and then between interven
tion and a second baseline phase. Three participants in the god-settin
g program, and one participant in the goal-setting and imagery program
, increased their mean free-throw performance from baseline to interve
ntion. However, three participants in the imagery program decreased th
eir mean free-throw performance from baseline to intervention. Goal di
screpancy scores also were investigated. A positive correlation was fo
und between participants' free-throw performance and personal goals.
