Other theories and models of arousal do not affirm the Hebb or Yerkes-Dodson curve. The widely supported theory of optimal flow presents a less simplistic understanding of arousal and skill-level match. Reversal theory actively opposes the Yerkes-Dodson law by demonstrating how the psyche operates on the principle bistability rather than ...
According to Eysenck's arousal theory of extraversion, there is an optimal level of cortical arousal, and performance deteriorates as one becomes more or less aroused than this optimal level. Arousal can be measured by skin conductance, brain waves or sweating. At very low and very high levels of arousal, performance is low, but at a better mid ...
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 ...
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.
The evaluation apprehension theory was proposed by Nickolas B. Cottrell in 1972. He argued that we quickly learn that the social rewards and punishments (for example, in the form of approval and disapproval) that we receive from other people are based on their evaluations of us. On this basis, our arousal may be modulated. In other words ...
Cantharidin can cause priapism — a type of painful, long-lasting arousal that can damage your member when left untreated. Priapism is a serious medical emergency that requires urgent attention ...
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.
One theory is that the secretion of various hormones during and after orgasm — including oxytocin, serotonin, and dopamine — play specific roles in limiting arousal and preventing arousal ...
