Abstract [en]

Testing facilitates memory retention more than studying. The current experiment aimed to investigate neural memory-related processes during repeated testing and studying, thereby contributing to more elaborate theories. 5 participants (aged 19-31) practiced word-pair associates during fMRI through repeated studying (40 pairs) and testing (40 pairs). One week later they returned for a test and the outcome was used to calculate subsequent memory differences during fMRI. Findings included higher subsequent memory difference in left parietal lobe, precuneus and superior frontal gyrus for the test condition, implying more elaborate semantic processing. Also, an interaction effect was found in anterior cingulate cortex, possibly indicating an early beneficial recruitment of memory enhancing functions in the test condition.

Abstract [sv]

Testning förbättrar minnesinlagring mer än studium. Det aktuella experimentet syftade till att undersöka neurala minnesrelaterade processer under upprepad testning och studium, och därmed bidra till mer konkreta teorier. 5 deltagare (i åldern 19-31) tränade ordpar (Swahili-Svenska) i en fMRI-scanner, antingen genom upprepat studium (40 par) eller upprepad testning (40 par). En vecka senare återvände de för ett slutgiltigt test på alla ordpar. Resultatet användes för att beräkna skillnader mellan lyckade och ej lyckade omgångar i fMRI-scannern. Högre skillnader i vänstra inferiora parietalloben, precuneus och superiora frontalgyrus hittades för testning jämfört med studium, vilket kan spegla en djupare semantisk bearbetning. En interaktionseffekt hittades i anteriora cingulate cortex, vilket möjligen indikerar en tidig rekrytering av fördelaktiga minnesfunktioner i test-betingelsen.
