Evidence: 88 • authority: 72

Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire, mobility, and reactivity. Arousal is mediated by several neural systems. Wakefulness is regulated by the ARAS, which is composed of projections from five major neurotransmitter systems that originate in the brainstem and form connections extending throughout the cortex; activity within the ARAS is regul…

A Quantum Model of Arousal and Yerkes Dodson Law. We present the Oscillating Field Perturbation (OFP) model, a quantum model that provides a quantitative account of the Yerkes-Dodson law concerning the relationship between arousal and performance. Inspired by neural models, OFP conceptualizes cognitive control as an oscillating field that perturbs a quantum system, and represents arousal as the ``gain'' induced by this field. By integrating OFP with the Multiple Particle Multiple Well (MPMW) framework, we demonstrate that OFP successfully explains how the shape of the Yerkes-Dodson law varies with task difficulty and familiarity, consistent with empirical findings. To the best of the author…

The Yerkes–Dodson law is an empirical relationship between arousal and performance, originally developed by psychologists Robert M. Yerkes and John Dillingham Dodson and published, in 1908, in the Journal of Comparative Neurology and Psychology. The law dictates that performance increases with physiological or mental arousal, but only up to a point. When levels of arousal become too high, performance decreases. The process is often illustrated graphically as a bell-shaped curve which increases and then decreases with higher levels of arousal. The original paper (a study of the Japanese house mouse, described as the "dancing mouse") was only referenced ten times over the next half century, y…

Optimum Level of Arousal (Yerkes–Dodson Law)

Psychostimulants and cognition: a continuum of behavioral and cognitive activation.. Psychostimulants such as cocaine have been used as performance enhancers throughout recorded history. Although psychostimulants are commonly prescribed to improve attention and cognition, a great deal of literature has described their ability to induce cognitive deficits, as well as addiction. How can a single drug class be known to produce both cognitive enhancement and impairment? Properties of the particular stimulant drug itself and individual differences between users have both been suggested to dictate the outcome of stimulant use. A more parsimonious alternative, which we endorse, is that dose is the…
