The purpose of this study was to compare a provided video demonstration and point lights display to learn a novel skill. For this purpose, 24 participants were divided into three groups including video, point lights display and control. Participants, in the acquisition phase, should perform 30 trials. According to the previously stated classification, demonstration groups observed the corresponding film 5 times before the first trial. They also observed the model before each throw in the subsequent trials. The control group received only verbal instructions. The accuracy and variability of intra limb coordination was calculated in relation to the model. The results showed that there was no difference between the groups movement accuracy measure, but the experimental groups performed more like the model than the control group in intra limb coordination measure. However, there was no difference among experimental groups. These results were interpreted in relation to the role of task constraints.
