Abstract: Sense of agency (SoA) refers to feeling in control of our actions, and also external events caused by them. The aim is to investigate the link between SoA and attention, using the Eriksen flanker task, testing if the availability of attentional resources, by varying action-outcome intervals in blocks, will result in corresponding differences in SoA ratings, which refers to the amount of control felt over the outcome (coloured circles) that is triggered by pressing response keys to presented stimuli. The hypotheses are: (1) longer time intervals will yield higher SoA ratings, (2) congruent trials will yield the highest SoA rating, followed by neutral (no flankers), and then incongruent trials, and (3) at longer time intervals, with sufficient attentional resources available, SoA ratings will have no significant difference for all three congruency conditions. Standard congruency effects were found on accuracy and reaction times, but there were no significant effects found for congruency, intervals and interaction on agency ratings. This was linked to presence of temporal predictability, which mitigated disruptive effects of contiguity due to the strong causal relationship established, and incongruency from proactive conflict processes. Further studies are recommended to investigate the effect of predictability on attentional resources and agency.
