| Abstract: | This study aimed to explore the role of isoluminant stimuli in reducing attentional capture in motor sequence learning using a Discrete Sequence Production (DSP) task. We predicted that using isoluminant stimuli could ignore later stimuli, improving performance in the DSP task. Participants were divided into three experimental groups: the Mix Incompatible group (MixInc), the Single Stimulus group (SinStim), and the Different Compatible group (DifCom)—each group practised by repeating two 4-key sequences, followed by three different test conditions. The Mix Incompatible group practised sequences with an isoluminant stimuli and incompatible Stimulus-Response (S-R) mappings, predicting that the isoluminant stimuli combined with incompatible S-R mappings would force participants to ignore the later stimuli and identify the sequence using only the first stimulus. The Single Stimulus group was provided with the complete sequence in terms of letters before the experiment and was required to complete the sequence based solely on the first stimulus. The Different Compatible group participated in a standard DSP task. Results showed that during the Single Stimulus test condition, where participants recreated the practised sequence based on the first stimulus, the Mix Incompatible group had significantly longer response times (RT) and higher error rates than the other groups. The Mix Incompatible group exhibited significant RT differences in the Random and Random Distractor conditions, which involved responding to a random order of stimuli, including isoluminant distractor stimuli. This indicates an inability to ignore isoluminant stimuli. The findings suggest that isoluminant stimuli with incompatible S-R mappings do not reduce attentional capture, indicating continued reliance on stimuli hindering motor sequence learning. |
