|
Term
| arousal can be activated by |
|
Definition
| emergency, danger, pain, sound |
|
|

Term
| sympathetic targets are activated -- |
|
Definition
|
|
Term
|
Definition
rest or digest, low arousal
conserves energy
acetylcholine |
|
|
Term
|
Definition
| sympathetic system is constantly activated. Constant stress response |
|

Definition
| Reticular activating system (RAS) |
|
|
Term
| Parts of the brain the RAS involves |
|
Definition
| Brainstem -> thalamus -> cortex |
|
|
Term
| RAS is different from -- pathways, acts more like a -- |
|
Definition
|
|
Term
| Surgically cut below medulla/before spinal cord of the RAS |
|
Definition
| animal is fine functions normal |
|
|
Term
| If RAS cut up at the top by thallamus |
|
Definition
| the animal was never aroused |
|
|
Term
| RAS activity is measured by |
|
Definition
|
|
Term
|
Definition
synchronized
high voltage, low frequency |
|
|
Term
| synchronized EEG would indicate whats going on in the brain? |
|
Definition
| (not diverse things going on in different areas of the brain) |
|
|
Term
|
Definition
desynchronized EEG
low voltage, high frequency |
|
|
Term
| Study the EEG of awake vs delta sleep |
|
Definition
|
|
Term
| Gary on top of the space needle and is afraid of heights, what does his brain waves on EEG look like? |
|
Definition
| Would be desynchronized, high arousal |
|
|
Term
| if you disconnect RAS from brain and present a stimulus what happens/ |
|
Definition
| synchronized EEG (sensory input, but no arousal) |
|
|
Term
| • Leave RAS intact & stimulate it w/electrical current |
|
Definition
| Even tho no “real” stimulus -> desynchronized EEG (no sig. sensory input, but general arousal) |
|
|
Term
| Bc the RAS reacts to electrical stim w/no actual stimulus what does it suggest? |
|
Definition
| RAS acts as an amplifier for the brain, it tells us what is important |
|
|
Term
|
Definition
| Increases attention/vigilance around stimuli in the environment |
|
|
Term
| 3 Theoretical models of arousal |
|
Definition
|
|
Term
energy model says arousal is -- that invigorates --
Is it homeostatic? |
|
Definition
energy
ongoing actions
non-homeostatic |
|
|
Term
| What two theories/studies fit into energy model? |
|
Definition
hull's generalized drive theory
Freuds concept of libido |
|
|
Term
regulatory model says arousal -- action by --
Is it homeostatic? |
|
Definition
| modulates action by maintaining appropriate activation levels (homeostatic) |
|
|
Term
| Generalized Drive Theory says arosal as |

Definition
| (produced by deprivation) motivational variable |
|
|
Term
|
Definition
| • High drive = high energy, very deprived = high motivation. |
|

Term
|
Definition
| with number of reinforcements/ learning |
|
|
Term
two rats trained to run maze for food. Rat 1 30d of training rat2 10d train. Both rats are deprived for 24 hours.
who runs faster? |
|
Definition
| rat 1 runs faster (from more learning H) |
|
|
Term
| Assumptions/ Predications of arousal in Generalized drive theory in which arousal is -- for action, but is -- so the organism will -- |
|
Definition
| • Arousal is necc. For action, but stressful (organism seeks to reduce it) |
|
|
Term
| • Well practiced skills-- from arousal while unpracticed -- from arousal |
|
Definition
practiced benefit
unpracticed will suffer from arousal |
|
|
Term
| Reason for training in jobs? |
|
Definition
| Bc you are bumping up the pool of energy (increasing habit), and stronger behaviors will be activated |
