Q

does the brain ever recover from a CNS injury?

A

the brain is able to reassign certian functions from the injured part to another part
if there’s a seizure, one full hemisphere is removed to prevent damage and more seizures

Q

dishabituation

A

after the process of habituation occurs, another stimulus occurs and interrupts the process of habituation

Q

positive vs negative recall
which is remembered more easily?
how does it work for people suffering from depression?
how does it work for older people?

A

positive memories are remember more easily; people with depression remember both equally; older adults show a stronger bias for positive vs negative memories

25
shallow vs deep processing
shallow: visual and/or sound processing deep: semantic processing
26
spreading activation
how semantic networks process recall events; thinking one node causes you to think of connected nodes. the shorter the connection, the faster the connection speed and the stronger the connection
27
stimulus types in classical conditioning: neutral unconditioned conditioned GIVE EXAMPLES
neutral: something that does not elicit a response. ex. bell for the dogs unconditioned: food presented to the dogs bc it causes salivation naturally, no learning required conditioned: something presented that does not happen naturally (correlated with the conditioned response of salivating when hearing the bell)
28
synaptic pruning
weak & least frequently used synapses are pruned while the most frequently used are strengthened
29
testing effect is?
Test -> Learn -> Rephrase normally testing is last but in this effect it comes before the actual learning
30
true or false: fresh long term memory is fragile
true: you need to be able to review this memory
31
true-false effect
true statements are verified more quickly than false statements
32
types of memories sensory working short term long term episodic semantic
sensory: information is first processed with this; short-lived working: actively engaged memory short term: sensory memory is converted into this for storage long term: essentially limitless episodic: things like your first day of school, graduation etc.; semantic: factual stuff like algebra
33
types of reinforcement positive negative
positive: giving something in order to encourage a behavior ( give a kid candy when he practices piano so that he keeps practicing) negative: removing something in order to encourage a behavior (remove a choire if he practices so that he keeps practicing)
34
types of punishment positive negative
positive: giving something to discourage behavior (giving a spanking when child arrives after curfew) negative: removing something to discourage a behavior (take away their phone when a child arrives home after curfew)
35
types of retrieval
recall: retrieval of memory recognition: associating info with an existing memory relearning: increased learning efficiency
36
typicality effect
using a typical example to increase recall ex. "robin is a bird" rather than saying "penguin is a bird"
37
what are the three types of encoding
Visual: encoding of image or visual acoustic: encoding of sound sematic: encoding meaning and understanding of information
38
What are the three types of memories
encoding, storage, retrieval
39
what causes a person to forget
insufficient repetition; cramming
40
what does operant conditioning entail
reinforcement or punishment of voluntary behavior
41
what is alzheimer's disease? what age does it affect people? what are the physiological changes (what are the two main things)?
-AD is a neurodegenerative disease causes memory loss, impaired cognition, and language degeneration -usually in older people, 65+ - B-amyloid plaques OUTSIDE the cell & neurofibrillary tangles INSIDE the cell
42
what is automatic vs controlled processing? give an example
things that you can do that takes no conscious effort ex. walking & talking on your phone) controlled processing is things that take thought such as solving a math problem
43
what is state dependent learning
memory is linked to a sight sound smell taste etc
44
what is the difference between memory and learning
memory is the storage and retrieval of information learning is a change in behavior due to experience
45
what is: acquisition extinction spontaneous recovery generalization discrimination
acquisition: when a stimuli has been acquired extinction: over time, the conditioned response will fade spontaneous recovery: if the conditioned stimulus is reintroduced, then the response comes back generalization: individuals will generalize a conditioned response discrimination: when you focus on one single stimuli while ignoring others
46
memory definition vs learning definition
memory: storage and retrieval of information learning: long lasting change in behavior resulting from experience
47
a working memory is the same as ________ memory. how long does it last?
short term; <30secs
48
explicit vs implicit memory
explicit: conscious and intentional recall implicit: automatic and unconscious recall
49
what is episodic memory
remembering specific events or situations
50
what is semantic memory
remembering facts and data
51
fixed interval vs variable interval
reinforcement is provided after a fixed amount of time has passed since the last reinforcement reinforcement is provided after an unpredictable amount of time has passed
52
fixed ratio vs variable ratio
fixed: reinforcement is provided after a fixed number of responses have occured variable: reinforcement is provided after an unpredictable number of responses have occured
53
escape learning vs avoidance learning
when punishment results in leaving a bad situation when punishment results in avoiding a bad situation altogether
54
rules based processing
humans can become aware that conditioning is occuring, skewing the results
55
latent learning
when humans/animals learn a behavior without a reward, and then demonstrate that behavior when a reward is presented
56
biological processes
it's much harder to associate a sense of nausea to a sound than a food
57
instrintive drift
animal can ignore conditioning in the presence of a strong instinctual driver (such as food)
58
what is weber's law
the minimum noticeable threshold is determined by the magnitude of the original stimulus ex. 5lb difference is much more noticeable when the original weight is 10lbs rather than 100lbs
59
describe sensation and threshold in terms of sensing the enviroment
sensation: detection of stimuli by receptors, which connect the stimuli into electrical impulses that can be interpreted by the CNS threshold: minimum difference between 2 stimuli that can be determined by the CNS
60
sensory adaptation is (physiological/psychological) and habituation is (physiological/psychological)
physiological psychological
61
rods vs cones define in terms of activity vision, concentration, and what can be seen
rods: low activity vision, highly concentrated, black & white cones: high activity vision, low concentration, sees colors
62
what do olfactory neurons do
convert ions and compounds in the air to electrical impulses that can be interpreted by the brain
63
where is does the brain taste form
thalamus
64
what is somatosensation
touch, texture, pain, pressure etc.
65
what is kinesthetic sense
body positioning and relative location/movement of joints and limbs
66
what is vestibular sense
balance and orientation
67
what does converging lens in the eye results in
forms a real positive inverted image
68
what effect does aging have episodic memory? how about semantic?
episodic: very sharp decline semantic: little to no decline
69
what is long term potentiation
the more you activate a synapse, the stronger that the synapse becomes
70
what is long term depression
the less you activate a synapse, the weaker that synapse becomes
71
what is the brain able to do after a traumatic brain injury?
brain is able to reassign functions that were damaged to healthy parts of the brain
72
social cognitive theory
theory that tries to explain behavior and learning
