Disentangling decision errors from action execution in mouse-tracking studies: The case of effect-based action control.

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.

Sequential adaptation to modality incompatibility.

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).

Sense of agency in social hierarchies.

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.

Action representations in prevention behavior: Evidence from motor execution.

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.

To prevent means to know: Explicit but no implicit agency for prevention behavior.

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.
