Sensorimotorset

Sensorimotorset, sometimes written as sensorimotor set, refers to a cognitive–motor state in which the sensory system and motor system are primed for efficient perception and action. In this view, perception is not passive; prior experience, expectations, and task demands bias sensory analyses toward information relevant for upcoming actions, while motor plans prepare specific responses.

Mechanisms underlying sensorimotorset involve learning, attention, arousal, and context. Neural activity in sensorimotor networks, including premotor and parietal areas, supports the ready alignment of perception and action. This state can modify how stimuli are weighted, speed up decision-making, and improve the speed and accuracy of motor responses when cues are aligned with the intended task.

Applications of the concept appear in sports training, rehabilitation, driving, and human–computer interaction. Trainers and researchers manipulate cues to evoke sensorimotorset, observing impacts on reaction times, accuracy, and fluidity of movement. It helps explain why performance can improve with familiarity, cue predictability, or focused attention, and why it may decline under fatigue or distraction.

Measurement and debates: sensorimotorset is an informal construct that overlaps with related ideas such as psychological set, attentional set, and priming. It is typically inferred from behavioral indices like reaction time and error rates, and sometimes explored with neuroimaging or electrophysiological methods. Ongoing discussion concerns its precise definition, boundaries with related constructs, and how best to operationalize it across tasks.
