Mouse-tracking experiment of a memory task
Description
This dataset contains a subset of data originally presented in Coco & Duran (2016). In this task participants see sentence and scene pairs that varied in plausibility and are requested to classify the pairs as congruent or incongruent. The experimental variables are congruency with two categorical levels (i.e., congruent, incongruent) and plausibility with two categorical levels (i.e., plausible, implausible). Participants have to classify each stimulus as belonging to one of these four levels.
The dataset contains two participants (I=2), each measured along three trials, two categorical variables (Q=2) each with two levels (K=2). The total number of trials is J=12. Mouse-tracking trajectories are raw-data, i.e. they have not been previously pre-processed.
