Psych Flashcards
What do parvocellular neurons specialize in?
parvocellular neurons specialize in picking up details (spatial resolution)
not great at detecting motion
What are hallucinogens?
drugs that distort perceptions, enhance sensations, and promote introspection
What is paternalism?
a pattern found with physicians who provide the treatment they believes is best without regard for the patient’s desires.
Like how parents make decisions on their children’s behalf, without necessarily giving them background information
What is representativeness heuristic?
Comparing people or groups to a prototypical example
estimating the likelihood of an event by comparing it to an existing prototype that already exists in our minds.
what’s typical
What is stage 2 of non-REM sleep?
- theta waves
- eye motion stops
- heart rate & breathing slow down
- memory consolidation
- k-complexes and sleed spindles
- bursts of activities
- k-complexes and sleed spindles
What is the function of the thalamus?
acts as a relay for information traveling through the brain and helping it get to where it needs to go

Where are magnocellular neurons and parvocellular neurons located?
the lateral geniculate nucleus

What is the function of ossicles in the ear?
ossicles amplify the vibrations of the tympanic membrane

What is the elaboration likelihood model?
focuses on attitude change and the factors that tend to promote it.
This model theorizes that a message may be processed either peripherally (shallowly) or centrally (in a more thorough manner).
Central processing tends to have a more long-lasting effects than peripheral processing, although both can alter attitude at least temporarily

What is the cocktail party effect?
The idea that we can “tune in” to a particular stimulus, like a name being said from across the room
background information is being processed to some degree even if its not the center of focus
What is a positive symptom?
positive symptoms are defined by their “presence” – an addition
What is a latent function?
Latent functions are those that are not specifically intended to occur. unconcious, unintended, and beneficial

What is social exchange theory?
individuals ground relationship decisions in their evaluation of the costs and benefits of maintaining each relationship

What is Neuropeptide Y?
A hormone that increases hunger
What is social-desirability bias?
the tendency for a study participant to alter their responses or selectively respond to a study questionnaire with responses that they think will make the experimenter like them more
Through what neural mechanism does caffeine work?
A mild central nervous system stimulant
promotes alertness by blocking adenosine receptors (a compound in the brain which promotes drowsiness)
What is an in-group?
categories that someone identifies as a member of
What muscle causes our pupils to dilate in response to a stimulus that triggers the fight or flight response?
pupillae muscle

What are 4 features of barbiturates and benzodiazepines?
- depressants
- increase GABA receptor activity (inhibitory neurons)
- treat anxiety and insomnia
- high risk of overdose, addiction, and withdrawal dangers
What is signal detection theory?
a means to measure the ability to differentiate between information-bearing patterns and random patterns that distract from the information
For example, if you are incredibly focused on driving your car you might notice road hazards even if they present at a relatively low intensity. However, if you are sleepily driving your car, then a road hazard may need to present itself at a much higher intensity for your brain to correctly detect it and produce a “hit”

What is parallel processing?
The act of integrating multiple inputs (color, shape, motion, etc.) spontaenously
What is the major function of the enteric nervous system?
regulates activity of the gut
What is primary appraisal?
Cognitive appraisal of stress consists of two stages: primary and secondary
During primary appraisal, the person analyzes the potential stressor along with the surrounding environment to determine whether it represents a threat

A loss/decrease of what neurotransmitter leads to Parkinson’s disease?
Dopamine
