Arousal and Performance (Chpt. 5) Flashcards
Arousal (Woodworth, 1918 & Hull, 1940)
is the activation of the brain (Reticular Activating system) RAS and the body (Autonomic nervous system) ANS
Arousal’ mainly means cortical arousal.
Most arousal theories are about ‘humans in general’ (not related to individual differences).
But introverts are cortically aroused’ more easily than extraverts.
Cortical arousal
Visual, Auditory, and Tactile sensory receptors
involves the activation of various brain systems often in combination with other systems as the task demands. The autonomic nervous system arouses the body again directing blood to those parts of the body again directing blood to those parts of the body that demand greater energy
Cortical activity, is caused by the hypothalamus, which triggers two parallel and complementary reactions. It stimulates activity in the autonomic nervous system and in the endocrine glandular system systematic nervous system a division of the autonomic nervous system
Fuster, 1958 Monkey study
Rhesus monkeys were required to learn to discriminate between 2 objects to learn which object had a food reward hidden under it when the objects were presented for a fraction of a second at a time. Speed and coordination of reactions under higher levels of arousal.
Electroencephalograms
The brain is composed of many interconnecting nerve pathways. Electrical impulses generated by chemical processes travel along these pathways. The electroencephalograph was designed to amplify these impulses so that permanent record could be made of the activity of various brain structures
Prefrontal cortex
executive function of the brain in goal oriented behavior
Optimal Stimulation Theory
individuals with high baseline levels of arousal should prefer lower levels of stimulation or lower levels of complexity whereas individuals with low baseline levels of arousal should prefer higher levels of incoming stimulation or higher levels of complexity
The most pleasant arousal is moderate. Does not explain Y-D law but maybe explained b Y-D law
Telic goals/ Reversal theory
They plan their activities carefully and tend to complete them to receive satisfaction that comes from achieving a goal.
Telic state serious minded, businesslike.
Paratelic state: playful, ‘having fun,’ sports.
Paratelic: High arousal is pleasant.
Pleasant ‘high arousal’ of paratelic state is the exact opposite of what ‘drive theory’ would predict.
Relaxation vs. Excitement (Paratelic)
Boredom vs. Anxiety (Paratelic)
Paratelic goals
They are inclined to prolong activities as long as they are producing high levels of pleasure
Relaxation
when we are in the achievement state, low arousal can be pleasant we call it relaxation
Pleasure seeking state
we call the same low level of arousal boredom. Similarly, high arousal can be very unpleasant (anxiety) in the achievement state and very pleasant (excitement) in the pleasure seeking state.
Negative Activation
avoidance system to keep organisms out of trouble it does this by inhibiting behaviors that might lead to pain, punishment, or some other negative consequence
Positive Activation
system is an approach system its function is to direct individuals to situations and experiences that could offer pleasure and reward
Trait arousal
characterizes the individual more or less independently of the situation or across situations
State arousal
arises out of the individual’s interaction with the environment
Brain arousal
Neocortex brain’s main decision maker the word cortex is from bark of tree means surrounding layer of brain. The RAS is sensitive to sensory info and can also be activated by non sensory brain sources
