Loudness, but not shot power, influences simple reaction times to soccer penalty sounds4

Abstract

Objective: The aim of the present study was to investigate how ecological sport sounds (i.e., foot-ball impacts of soccer penalty kicks) affect simple reaction times. Design: Three within-subjects, simple reaction time experiments were carried out; they differed among each other for the manipulations performed on the stimuli. Method: In Experiment 1, the loudness of the stimuli was manipulated; instead, in Experiment 2 and 3 shot power was manipulated, using as stimuli impacts of shots with different speeds. Results: The results highlighted an inverse relation between stimuli loudness and reaction times; instead, the natural differences among shots with different power were not sufficient to influence reaction times. Conclusions: Sounds associated to different shot power seem to differ in parameters which are not actually relevant for simple reaction times. Future studies should further investigate on similar issues, better clarifying whether the properties of ecological sounds can naturally influence reaction times.
