Explanation of the velocity profile plots. For all (time-normalized) trajectories, the timepoint of maximal orthogonal deviation (MAD) from the ideal line is computed (left). Trajectories are then separated into pre-and post-MAD parts (middle). The resulting subtrajectories are time-normalized again before velocities can be aver-

Mouse-tracking is regarded as a powerful technique to investigate latent cognitive and emotional states. However, drawing inferences from this manifold data source carries the risk of several pitfalls, especially when using aggregated data rather than single-trial trajectories. Researchers might reach wrong conclusions because averages lump togethe...

... (right). Although participant averages (thin lines) are smooth and do not cross our exclusion criterion, the response-effect compatibility effect in spatial measures completely vanishes when multi-step movement trials are excluded: Compatible (blue) and incompatible (red) average trajectories overlap for single-step movements the movement (see Fig. 4 for an explanation of this novel procedure). Table 1 provides a summary over all re-analyzed experiments, highlighting how the results change when multi-step movements are excluded with the proposed cutoff criterion. Due to consistency in the pattern of results across all experiments, we textually describe only one re-analysis in ...
