Task-set inhibition involves suppressing interference from recently performed tasks. Previous research has demonstrated that returning to a recently abandoned task (e.g. ABA) is more difficult than switching to a less recently abandoned one (e.g. CBA), as indicated by slower reaction times (RTs) and higher error rates. Although this mechanism has been consistently observed in cued task-switching paradigms, it remains unclear whether it impacts the decision-making process in voluntary task selection. The present study investigated whether task-set inhibition operates in both cued and voluntary task-switching paradigms, and how it influences task selection processes. Thirty-six participants performed two task-switching paradigms. In the cued version, participants were required to switch between three tasks (parity, size and distance) according to the presented cue. In the voluntary version, participants decided voluntarily the task to perform among one of these three tasks, avoiding consecutive repetitions. Preliminary results showed an inhibitory effect in both paradigms, with ABA sequences being slower than CBA sequences. In the voluntary switching paradigm, differences between sequences persist independently of task type when considering reaction times (RTs), but not when considering 'choice proportion'. In the cued switching paradigm, results revealed a significant interaction between task type and sequence, suggesting a task-dependent control mechanism. These results suggest that task-set inhibition operates as a general cognitive mechanism. However, the differential patterns observed between cued and voluntary conditions highlight the complex interplay between this mechanism and switching processes. Further research could focus on generalizing findings to different settings and populations, and on understanding the impact of representativeness during the decisional process.
