10.26165/JUELICH-DATA/F8WCGM Mengotti, Paola0000-0001-8427-1737(INM-3) Jülich DATA 2025 This dataset comprises behavioural data of from a longitudinal (2 sessions, 2 weeks apart) online study with two versions of a cueing task (spatial and motor) with changing predictive value of the cue. In the spatial task, participants were asked to orient their attention towards the left/right hemifield based on the spatial cue and respond to the target, by indicating its missing corner. Raw data of 40 participants (mean age ± SD: 31 ± 5 years; 18 females, 22 males) who completed both sessions are presented here. In the motor task, participants were asked to prepare the most probable motor response (left/right index finger) based on the motor cue and respond to the target, by indicating its missing corner. Raw data of 43 participants (mean age ± SD: 28 ± 5 years; 19 females, 24 males) who completed both sessions are presented here. This dataset includes also the stimuli used in experiment 1 and 2, the code of the experiment is not available due to its online format implemented in Gorilla (https://gorilla.sc). This dataset includes also the code for the behavioral and modelling analyses. Mengotti, Paola(INM-3)
