Kaplan Behavioral Science Unknown Concepts Flashcards
1
Q
What are reflex arcs?
A
interneurons in the spinal cord relay information to the source of stimuli and to the brain simultaneously
2
Q
How is the nervous system divided?
A
central nervous system = brain + spinal cord
peripheral nervous system = cranial + spinal nerves
1) somatic
2) autonomic = para and symp
3
Q
What are the main parts of the forebrain and their functions?
A
thalamus = relay station for sensory info
hypothalamus = homeostasis + endocrine system through a portal system that connects to anterior pituitary
basal ganglia = smooth movement + posture
limbic system = controls emotion and memory
- septal nuclei = pleasure, addiction
- amygdala = fear and aggression
- hippocampus = consolidates memories
cerebral cortex
- frontal = executive function, motor function
- parietal = somatosensation, spatial processing
- occipital = vision
- temporal = sound processing, speech perception, memory, emotion
4
Q
What is the most important peptide neurotransmitter to know?
A
endorphins = natural painkillers produced by the brain
- neuromodulator: slow, longer effects than NT
5
Q
Describe the disorders associated with dopamine.
A
Dopamine hypothesis of schizophrenia: delusions, hallucinations, and agitation arise from either too much dopamine or oversensitivity to it
Parkinson’s Disease: associated with loss of dopaminergic neurons in the basal ganglia
- bradykinesia, postural instability
6

A
gross to fine, head-to-toe order, core-to-periphery
10
Q
Describe social development in infants.
A
parent-oriented (separation anxiety, stranger anxiety) –> self-oriented (parallel play) –> other-oriented
11
Q
What is a threshold?
A
minimum stimulus that causes a change in signal transduction
- absolute threshold = minimum stimulus energy that is needed to activate a sensory system
- threshold of conscious perception = creates signal large enough in size and duration to be brought to awareness
- JND = minimum difference in magnitude between 2 stimuli before one can perceive the difference
12
Q

vestibulocochlear nerve–>MGN of the thalamus–> auditory cortex of temporal lobe
15
Q
What is responsible for pain perception?
A
nociceptors
- gate theory of pain: pain sensation is reduced when other somatosensory signals are present
16
Q
What is habituation? What is dishabituation?
A
repeated exposure to the same stimulus causes a decrease in response
recovery of a response to a stimulus AFTER habituation has occurred
17
Q
What is associative learning?
A
creation of pairing between two stimuli or between a behavior and a response
- classical or operant conditioning
18
Q
What is classical conditioning?
A
takes advantage of biological, instinctual responses to create associations between two unrelated stimuli
19
Q
What is an unconditioned stimulus vs. an unconditioned response? Compare to the conditioned situation.
A
unconditioned stimulus brings about reflexive unconditioned response
conditioned stimulus is normally neutral that through association causes a reflexive, conditioned response
Entire process = acquisition
loss of conditioned response = extinction
- spontaneous recovery reverses
20
Q
What is generalization? what is discrimination in classical conditioning?
A
a stimulus similar enough to the conditioned stimulus can produce a conditioned response
distinguish between similar stimuli
21
Q
What is operant conditioning? How does it relate to behaviorism?
A
way consequences change the frequency of voluntary behaviors
- theory that all behaviors are conditioned
22
Q
Compare reinforcement to punishment.
A
Reinforcement: increasing the likelihood of a behavior
- positive: add positive consequence or incentive = $$$
- negative: remove something unpleasant = escape learning + avoidance learning
Punishment: reduce the occurrence of a behavior
- positive: adds unpleasant consequences
- negative: removing stimulus to reduce behavior
23
Q
Name the types of reinforcement schedules in decreasing order of effectiveness.
A
- variable-ratio: reinforce a behavior after a varying number of performances of that behavior, with the average # of performances remaining the same
- gambling addiction - fixed-ratio: reinforce a behavior after a specific amount of performances
- variable interval: reinforce a behavior the first time that behavior is done after a varying amount of time
- fixed interval: reinforce the first instance of a behavior after a specific time has elapsed
24
Q
What is shaping in operant conditioning?
A
rewarding increasingly specific behaviors that come closer to a desired response
25
What is latent learning?
learning that occurs without a reward, but is then spontaneously demonstrated once a reward is introduced
26
What is automatic processing? What is controlled processing?
information gained without any effort
- passively absorbed from your environment

28
What are the methods of encoding?
1. Mnemonics: acronyms or rhyming phrases that provide organization
- method of loci: associating each item in a list with a location along a route
- peg-word system: associating numbers with items that rhyme with or resemble the numbers
2. Chunking: taking individual elements of a large list and grouping them together
29
What are the different types of memory?
sensory: <1 s, iconic + echoic
short-term memory: <1 min without rehearsal
- working memory: integrates STM, attention, executive function to manipulate information
long-term memory: lifetime

- retrograde and anterograde amnesia
- confabulation: creating vivid, but fabricated memories
caused by alcoholism
32
What is the misinformation effect?
person's recall of an event becomes less accurate due to the injection of outside information into the memory
33
What is source-monitor error?
confusion between semantic and episodic memory: a person remembered the details of an event, but confuses the context where they gained them
34
What is neuroplasticity?
the brain's ability to change and adapt to new experiences and stimuli by changing synaptic connections
- children are extremely plastic
35
What is synaptic pruning?
weaker neural connections are broken while stronger ones are bolstered, increasing processing efficiency
36
What is LTP?
the strengthening of neural connections through repeated use; basis of long-term memory
- increase in NMDARs (Glu receptors) and NT release is required
37
What is the dual-coding theory?

- "tree" and a pic of a tree recalls similar information
38
What is the information processing model? What are the pillars?
encoding -- storage --retrieval
1. Thinking starts with sensing, encoding, and storing information.
2. The brain analyzes the information to guide decisions.
3. Apply and adapt previous solutions to new problems.

- conclusion is probable, but NOT guaranteed
48
What is heuristic?
simplified principles used to make decisions
- "rules of thumb"

3) drive reduction theory: desire to eliminate drives (internal states of tension)
- primary drives: related to bodily processes
- secondary drives: stem from learning, including accomplishments and emotions
4) satisfy needs: primary (physiological) and secondary (mental states)
Maslow's hierarchy of needs prioritizes into 5 categories
- physiological needs, safety/security, love and belonging, self-esteem, self-actualization (realize one's full potential)
