Abstract:The aim of this study was to find out whether motor sequence learning could contribute to less perceptual attention, which in turn caused reduced Stroop conflict. Thirty two students of the University of Twente completed a computer task that consisted of the Discrete Sequence Production (DSP) Task and the Stroop Task. Subjects had to react to the ink color of a color word, while disregarding the meaning of the word. In this study, subjects of one group practiced two fixed motor sequences (each sequence consisted of six key presses) across six blocks while the subjects of the other group did not. After the training phase, the sequence training group was presented with two familiar and two unfamiliar sequences in the test phase. Results showed that subjects in the sequence training group showed smaller Stroop effect when they performed motor sequences that they previously had learned compared to when they were exposed to unfamiliar sequences. But this was only the case when reaction times of the first key press were omitted. Furthermore, this group did not overcome the Stroop effect completely when confronted with familiar sequences. The results were in line with the Dual Processor Model of sequencing skill. The findings suggested that motor sequence learning reduced Stroop effect. Future research could focus on whether repeated exposure to the task (without fixed sequences being presented) would reduce Stroop conflict, which would suggest increased cognitive control.
