Abstract [sv]

Syftet med denna studie var att undersöka om träning av exekutiva funktioner kan påverka den intra-individuella variabiliteten (IIV) i reaktionstid hos unga vuxna och äldre. De 29 yngre och 30 äldre deltagarna i studien delades upp i två grupper, en träningsgrupp som gick igenom 15 sessioner av träning i exekutiv funktion och en kontrollgrupp som endast deltog vid pre- och posttestning. I träningsbatteriet tränades de exekutiva funktionerna uppdatering, skiftning och inhibering i enlighet med det teoretiska ramverk om exekutiv funktion som skapats av Miyake (2000). I studiens pre- och postmätningar användes reaktionstidsdata från tre tester: Serial Reaction Time (SRT), Flanker och Alternating Runs. Dessa tester skiljde sig från de som användes i träningsbatteriet. Resultaten visade inte på några signifikanta skillnader vad det gällde möjligheten att träna sig till homogenitet i IIV. Dock fanns det skillnader i IIV i ålder på gruppnivå i de mer komplexa uppgifterna Flanker och Alternating Runs där den äldre försöksgruppen var signifikant mer heterogen än den yngre, vilket är i linje med tidigare forskning. Vi fann också en huvudeffekt av betingelse på båda dessa tester. Detta betyder att alla grupper hade en signifikant högre IIV om betingelsen var mer kognitivt utmanande.

Abstract [en]

The purpose with this study was to examine if training of executive functions can have an influence on the intra-individual variability (IIV) in reaction time in young and older adults. The 29 young and 30 older participants in the study were divided into two groups, one that went through 15 sessions of training in executive functions and one that only participated in pre- and post-testing. The executive functions that were trained were updating, shifting and inhibition in accordance with the theoretical framework made by Miyake (2000). In this study the reaction time data from three cognitive tests were used: Serial Reaction Time (SRT), Flanker and Alternating Runs. These tests were slightly different from the ones used in the training battery. The results did not show any significant differences on the possibility to decrease IIV with training in executive functions. The younger and older adults did differ in IIV on Flanker and Alternating Runs with the older adults being significantly more heterogeneous as a group, which is in line with earlier research. We also found main effects of trials in both these tests which would mean that all groups had a significantly higher IIV on trials that were more challenging for the cognitive functions.
