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 together two distinct contributions that speak towards fundamentally different mechanisms underlying between-condition differences: influences from online-processing during action execution and influences from incomplete decision processes. Here, we propose a simple method to assess these factors, thus allowing us to probe whether process-pure interpretations are appropriate. By applying this method to data from 12 published experiments on ideomotor action control, we show that the interpretation of previous results changes when dissociating online processing from decision and initiation errors. Researchers using mouse-tracking to investigate cognition and emotion are therefore well advised to conduct detailed trial-by-trial analyses, particularly when they test for direct leakage of ongoing processing into movement trajectories., Competing Interests: Declarations.

Modality-compatible stimulus-response mappings (e.g., responding vocally to an auditory stimulus and manually to a visual stimulus) are often easier to perform than modality-incompatible sets (reversed modality mappings). Here, we investigate sequential, trial-to-trial, modulations of modality compatibility effects. By reanalyzing a previous experiment and conducting two specifically tailored, new experiments, we demonstrate robust within-task sequential modulations. Furthermore, we test for between-task adaptations by intermixing the modality switching task with a Simon task. Results show reliable sequential adaptations within the modality switching task, but no transfer of adaptation between tasks in either direction. We discuss how a combination of prominent theoretical accounts such as conflict adaptation and episodic binding can serve as the cognitive underpinnings of the observed sequential adaptations.

Distributing complex actions across agents is commonplace in human society. The objective efficiency of joint actions comes with critical challenges for the sense of agency of individual agents, complicating an accurate formation of these agents' perceived control over actions and action outcomes. Here we report a new experimental paradigm to investigate sense of agency for supervisors and subordinates in hierarchical settings. Results indicate profound differences in the sense of agency between both roles, while also indicating additional contributions of such situational factors as degrees of freedom, action decision versus action execution, outcome valence, and veto options. We further observed a tight coupling of sense of agency and sense of responsibility, with only weak links to affective responses to the action outcome.

Human actions sometimes aim at preventing an event from occurring. How these to-be-prevented events are represented, however, is poorly understood. Recent proposals in the literature point to a possible divide between effect-producing, operant actions, and effect-precluding, prevention actions, suggesting that the control of operant actions relies on codes of environment-related effects whereas prevention actions do not. Here we report two experiments on this issue, showing that spatial features (Experiment 1) as well as temporal features (Experiment 2) of to-be-prevented events influence actions in the same way as corresponding features of to-be-produced effects. This implies that selecting and executing prevention actions relies on anticipated environmental changes, comparable to operant actions., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023 Elsevier B.V.

Human agents draw on a variety of explicit and implicit cues to construct a sense of agency for their actions and the effects of these actions on the outside world. Associative mechanisms binding actions to their immediate effects support the evolution of agency for operant actions. However, human agents often also act to prevent a certain event from occurring. Such prevention behavior poses a critical challenge for the sense of agency, as successful prevention inherently revolves around the absence of a perceivable effect. By assessing the psychological microstructure of singular operant and prevention actions we show that this comes with profound consequences: agency for prevention actions is only evident in explicit measures but not in corresponding implicit proxies. These findings attest to an altered action representation in prevention behavior and they support recent proposals to model related processes such as avoidance learning in terms of propositional rather than associative terms., (Copyright © 2020 Elsevier B.V.
