Arousal
Arousal is important in regulating consciousness, attention and information processing. It's crucial in response situations, mobility, eating right, the fight-or-flight response and sexual activity. Hans Eysenck claims the difference in arousal levels causes introversion or extroversion. The arousal level, the same, reaction to stimulus is individual.
The Yerkes-Dodson law states there is an optimum level of arousal for performance, too little or too much can affect task adversity. Easterbrook says an increase of arousal leads to a decrease in the number of cues used.
In psychology, arousal is described as a response to a difficult challenge from a subject with moderate skills.
A person with low arousal reacts less to stimuli than one without. Hare calls this a chronic state of 'stimulus-hunger', a claim more sensory inputs are needed to feel normal.
Latent learning is when you learn something, but it's not immediately put to use.
In a classic experiment, rats were put in a maze. Group one always found food at the end of the maze. Group two never did find food. Group three found food only on the eleventh day, not any sooner. Group one quickly learned to rush to the end of the maze for food. Group two never learned to go to the end. Group three acted like Group two up until the eleventh day.
