Experimental sport psychology studies cognitive processes underlying performance with the aim of its optimization. Twenty goalkeepers were tested by using a temporal occlusion paradigm. The experimental variable was the amount of visual information provided by the penalty kicker during the run-up. Fifteen kickers shot 40 penalties for each of 4 sectors in which the goal was divided. At the centre of each sector a light bulb marked the target zone. In the baseline condition, the kickers were told in advance where to kick, while in the other conditions they started the run-up without knowing where to shoot. The temporal gap between the visual stimulus presentation and the foot-ball contact was set on 3 anticipation levels: RT ( kicker’s reaction time), RT + 300 ms, RT + 600 ms. Result show that the best goalkeeper’s performance corresponded to the baseline condition, whilst a performance decrease was observerd for RT condition. The results underline the relevance of available visual cues and of the temporal factors connected to efficiency of anticipation skills.

Abstract
Experimental sport psychology studies cognitive processes underlying performance with the aim of its optimization. Twenty goalkeepers were tested by using a temporal occlusion paradigm. The experimental variable was the amount of visual information provided by the penalty kicker during the run-up. Fifteen kickers shot 40 penalties for each of 4 sectors in which the goal was divided. At the centre of each sector a light bulb marked the target zone. In the baseline condition, the kickers were told in advance where to kick, while in the other conditions they started the run-up without knowing where to shoot. The temporal gap between the visual stimulus presentation and the foot-ball contact was set on 3 anticipation levels: RT ( kicker’s reaction time), RT + 300 ms, RT + 600 ms. Result show that the best goalkeeper’s performance corresponded to the baseline condition, whilst a performance decrease was observerd for RT condition. The results underline the relevance of available visual cues and of the temporal factors connected to efficiency of anticipation skills.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
