Stimulussuch

Stimulussuch is a term used in German-language psychology to describe the process or tendency to seek external sensory input. It encompasses behaviors aimed at obtaining novel or intense stimuli to regulate arousal or information intake. It is often discussed as a facet of motivation or exploration.

The term derives from stimuli and such, and appears in literature on behavior, learning, and human–computer interaction. It is sometimes used to describe a task in experiments designed to quantify how much a subject will explore environments or seek out rewarding stimuli. The term is less standardized than related concepts like curiosity, novelty seeking, or sensation seeking, and its exact definition can vary by author.

Theoretical accounts link stimulussuch to reward systems in the brain, especially dopaminergic signaling, norepinephrine, and cortical arousal. Experimental measures include exploration duration in a maze, frequency of checking for new stimuli, eye-tracking toward novel stimuli, and performance in information-seeking tasks. It may be modulated by age, prior experience, context, and clinical conditions.

In human–computer interaction, stimulussuch informs adaptive interfaces that present stimuli to maintain engagement. In psychology, it is often discussed alongside curiosity, sensation seeking, and novelty seeking; some researchers treat stimulussuch as a broader or different construct.
