Abstract (Swedish)
Tidigare forskning på diverse olika sporter har visat att mått på visuell kontroll, exempelvis tidig och lång sista blickfixering på målobjektet (Quiet Eye Onset och Quiet Eye Duration) innan en kritisk fas av kinetisk aktivitet hänger ihop med positivt utfall på precisionsuppgifter. Mått på kinetisk aktivitet har också studerats och visat att exempelvis maxhastighet i rörelsen är lägre på träffar vid vissa uppgifter. Även arbetsminneskapacitet har visats vara en faktor som påverkar variationen på dessa mått. Inga tidigare studier har dock till uppsatsförfattarnas kännedom undersökt ovanstående fenomen för datoriserade precisionsuppgifter. Syftet med aktuell studie var därför att försöka replikera tidigare forskningsfynd gällande visuell... (More)

Även arbetsminneskapacitet har visats vara en faktor som påverkar variationen på dessa mått. Inga tidigare studier har dock till uppsatsförfattarnas kännedom undersökt ovanstående fenomen för datoriserade precisionsuppgifter. Syftet med aktuell studie var därför att försöka replikera tidigare forskningsfynd gällande visuell och kinetisk kontroll på datoriserade precisionsuppgifter. En grupp män mellan 18-30 år (n = 16) fick genomföra två datoriserade test där måltavlor på en datorskärm skulle skjutas ner, samtidigt som mått på visuell och kinetisk kontroll registrerades med eye-tracker och dator. I det senare deltestet manipulerades arbetsminnesbelastningen genom en reverse-Stroop betingelse. Resultatet visar att flertalet fynd gällande visuell och kinetisk kontroll gått att replikera här och att ökad arbetsminnesbelastning påverkar dessa mått. Variation i måltavlornas durationstid mellan deltesten utgör dock en confounder och mer forskning krävs för att säkra slutsatser ska kunna dras. (Less)
Abstract
Previous research on various sports has shown that aspects of visual control, namely an earlier onset and longer duration of the final fixation on the target (Quiet Eye Onset and Quiet Eye Duration) before a critical movement is associated with successful outcome on a precision task. Measurements on kinetic activity have also been studied and shown that hits are associated with lower max velocity of the movement for certain tasks. Working memory capacity has also been shown to have an impact on these measurements. No previous studies have, to the knowledge of the authors, investigated these phenomena on computerized precision tasks though. The purpose of this study was to investigate if previous findings regarding visual and kinetic... (More)
Previous research on various sports has shown that aspects of visual control, namely an earlier onset and longer duration of the final fixation on the target (Quiet Eye Onset and Quiet Eye Duration) before a critical movement is associated with successful outcome on a precision task.

No previous studies have, to the knowledge of the authors, investigated these phenomena on computerized precision tasks though. The purpose of this study was to investigate if previous findings regarding visual and kinetic control could be replicated on such tasks. A group of men aged 18-30 years (n = 16) completed two subtests on a computer where the purpose was to shoot down stationary targets while measurements on kinetic and visual control were recorded. Working memory load was manipulated using a reverse-Stroop task. The results show that many findings regarding visual and kinetic control were indeed replicable and susceptible to influence from increased working memory load. Due to confounders, further research is required to validate these findings. (Less)
