Arousal
oMobilization or activation in preparation of actual behaviour
oActivation of the brain and body
Selective Attention
oHigh levels of arousal
oNarrow attention to classify new info
Negative Activation System
oAvoidance, inhibiting, when we are threatened
Positive Activation System
oApproach, directed toward pleasure and reward
Stimuli
oCue function
Determines type of response
oArousing function
Determine intensity of response
Collative Variables

Novelty- new and different
Complexity- # elements and dissimilarity
Incongruity- Difference, conflicting
Incentives
oStimuli that elicit affective response
Attract or repel, positive or negative
Can heighten arousal

location and identification of things in the environment that might threaten
our survival

Document Summary

Determine intensity of response: stimuli, collative variables, stimuli characteristics that include. Can heighten arousal: tasks, activity in order to attain incentive. Chapter 5: arousal, characterizes the individual more or less independently of the situation, characterization across situations, continuous state. How on approaches: state arousal apprehension, transitory emotional response involving feelings of tension and, arises out of the individuals interaction with the environment, 2 types. Sensory overload: over stimulation, complex environment. Cognitive dissonance: when two pieces of info are contradictory, narrow attention. Chapter 6: biological rhythms, periodic fluctuation in a bio system, endogenous biological rhythms, when arousal becomes very high our attention is directed toward the location and identification of things in the environment that might threaten our survival. Every 24 hours: circadian rhythms, infradian, ultradians. Chapter 7: drug addiction, uncontrollable craving controversial, generally depends upon a physiological need created by the lack of drug.
