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 ...
Eysenck's three-factor model of personality was a causal theory of personality based on activation of reticular formation and limbic system. The reticular formation is a region in the brainstem that is involved in mediating arousal and consciousness. The limbic system is involved in mediating emotion, behavior, motivation, and long-term memory.
Frederick Toates presented a model of sexual motivation, arousal, and behavior in 2009 that combines the principles of incentive-motivation theory and hierarchical control of behavior. The basic incentive-motivation model of sex suggests that incentive cues in the environment invade the nervous system, which results in sexual motivation ...
High levels of vasopressin can lead to decreases in sexual motivation for females. [13] A link between vasopressin release and aggression has been observed in females, which may impair female sexual arousal and sexual motivation by leading to feelings of neglect and hostility toward a sexual partner.

Gray's biopsychological theory of personality was informed by his earlier studies with Mowrer on reward, punishment, and motivation and Hans Eysenck's study of the biology of personality traits. [8] Eysenck linked Extraversion to activation of the ascending reticular activating system , an area of the brain which regulates sleep and arousal ...
The Biopsychological Theory of Personality was created in 1970 after Gray disagreed with Hans Eysenck's arousal theory that dealt with biological personality traits. [8] According to Eysenck, differences in extraversion are a result of differences in sensitivity of the ascending reticular activating system. [ 9 ]
The reward system (the mesocorticolimbic circuit) is a group of neural structures responsible for incentive salience (i.e., "wanting"; desire or craving for a reward and motivation), associative learning (primarily positive reinforcement and classical conditioning), and positively-valenced emotions, particularly ones involving pleasure as a core component (e.g., joy, euphoria and ecstasy).
Distraction-conflict is an alternative to the first tenet in Zajonc's theory of social facilitation. This first tenet currently seems to be more widely supported than the distraction-conflict model. Zajonc formulates that the presence of an individual generates arousal, and this arousal facilitates well-learned tasks and inhibits complex tasks.
