In the literature it can be found that acoustic information can influence motor performance. This suggests that sound can provide a mental temporal motor representation of the movement itself. Voluntary movements can be decomposed in the relative timing component and the overall duration component. Movement recognition is an important aspect in both daily life and sport activities. The present work was aimed to investigate whether golfers are able to discriminate between the sounds associated to their own from other golfers' swings. The main goal of the experiment was to study the role of the temporal structure of the stimuli. Participants were provided with acoustic cues produced during the swing. A manipulation of movements overall duration and relative timing was applied to others’ tracks, leading to the creation of five stimuli, corresponding to five experimental conditions: participant's swing sound, other golfers' sounds having equal both relative timing and overall duration, other golfers' sounds having equal relative timing but different overall duration, other golfers' sounds having different relative timing but equal overall duration, and other golfers' sounds having both different relative timing and overall duration. The task of the participants was to say whether each sound corresponded or not to their own swing. Results show that participants were able to identify their own movements, and wrongly recognize others’ tracks as their own, when both overall duration and relative timing were equal to individual sounds. These conditions are significantly different from the other ones. This suggests that the temporal features are quite relevant in the sound recognition of a motor action, but they are not the only information provided by the sound. Therefore, these findings provide further evidence to the relevance of timing for auditory movement recognition and are consistent with recent Gestalt interpretations of motor control.

Abstract
In the literature it can be found that acoustic information can influence motor performance. This suggests that sound can provide a mental temporal motor representation of the movement itself. Voluntary movements can be decomposed in the relative timing component and the overall duration component. Movement recognition is an important aspect in both daily life and sport activities. The present work was aimed to investigate whether golfers are able to discriminate between the sounds associated to their own from other golfers' swings. The main goal of the experiment was to study the role of the temporal structure of the stimuli. Participants were provided with acoustic cues produced during the swing. A manipulation of movements overall duration and relative timing was applied to others’ tracks, leading to the creation of five stimuli, corresponding to five experimental conditions: participant's swing sound, other golfers' sounds having equal both relative timing and overall duration, other golfers' sounds having equal relative timing but different overall duration, other golfers' sounds having different relative timing but equal overall duration, and other golfers' sounds having both different relative timing and overall duration. The task of the participants was to say whether each sound corresponded or not to their own swing. Results show that participants were able to identify their own movements, and wrongly recognize others’ tracks as their own, when both overall duration and relative timing were equal to individual sounds. These conditions are significantly different from the other ones. This suggests that the temporal features are quite relevant in the sound recognition of a motor action, but they are not the only information provided by the sound. Therefore, these findings provide further evidence to the relevance of timing for auditory movement recognition and are consistent with recent Gestalt interpretations of motor control.
