The Yerkes–Dodson law is an empirical relationship between arousal and performance, originally developed by psychologists Robert M. Yerkes and John Dillingham Dodson in 1908. [1] 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 ...
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 ...
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 ...
The hormones oxytocin and vasopressin are implicated in regulating both male and female sexual motivation. Oxytocin is released at orgasm and is associated with both sexual pleasure and the formation of emotional bonds. [13] Based on the pleasure model of sexual motivation, the increased sexual pleasure that occurs following oxytocin release ...

It was developed by philosopher John Dewey and named for two 19th-century scholars, William James and Carl Lange (see modern criticism for more on the theory's origin). [1][2] The basic ...
The two-factor theory of emotion posits when an emotion is felt, a physiological arousal occurs and the person uses the immediate environment to search for emotional cues to label the physiological arousal. The theory was put forth by researchers Stanley Schachter and Jerome E. Singer in a 1962 article. According to the theory, emotions may be ...
In the 1950s, British psychologist Hans Eysenck theorized that the trait of introversion-extraversion could be explained in terms of Clark Hull's drive theory of motivation. He later developed his own arousal theory to explain individual differences in the trait, suggesting that the brains of extraverts were chronically under-aroused, leading ...
