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 decreases.
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 ...
Being exposed to female ovulating cues may increase testosterone, which in turn may increase males' motivation to engage in, and initiate, sexual behaviour. Ultimately, these higher levels of testosterone may increase the reproductive success of males exposed to female ovulation cues. The relationship between testosterone and female sexual ...
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 ...
Daniel Ellis Berlyne (April 25, 1924 – November 2, 1976) [1] was a British and Canadian psychologist. Berlyne worked at several universities both in Canada and the United States. His work was in the field of experimental and exploratory psychology. Specifically, his research focused on how objects and experiences are influenced by and have an ...
Motivational intensity and arousal are related, but are considered to be separate ideas; arousal has implications for action, but motivational intensity does not and it is possible to experience high levels of arousal, but not experience motivational intensity (e.g., laughing).
Sexual desire is an emotion [ 1][ 2] and motivational state characterized by an interest in sexual objects or activities, or by a drive to seek out sexual objects or to engage in sexual activities. [ 3] It is an aspect of sexuality, which varies significantly from one person to another and also fluctuates depending on circumstances.
