Q

ironic processes of mental control

A

proposes that such ironic errors occur because the mental process that monitors errors can itself produce them

25
freudian theory and the activation-synthesis model differ how?
freud's theory: dreams begin with meaning | activation: dreams begin randomly, but meaning can be added as the mind lends interpretations in the process of dreaming
26
freudian theory
dreams are confusing and obscure because the dynamic unconscious creates them to be that way -problem is that there are so many interpretations `
27
psychoactive drugs
chemicals that influence consciousness or behavior by altering the brain's chemical system
28
depressants
substances that reduce the activity of the central nervous system - calming effect - tend to induce sleep in high doses - ex: alcohol
29
expectancy theory
suggests that alcohol effects can be produced by people's expectations of how alcohol will influence them in particular situations
30
myopia
theory that proposes that alcohol hampers attention, and leads people to respond in simple ways to complex situations
31
stimulants
substances that excite the central nervous system, heightening arousal and activity levels - increase the levels of dopamine and norepinephrine in the brain - ex: caffeine, amphetamines, nicotine, cocaine, ecstasy
32
amphetamines (also called speed)
- originally prepared for medical uses and as diet drugs | - when widely abused, they can cause insomnia, aggression, and paranoia with long-term use
33
marijuana
plant whose leaves and buds contain a psychoactive drug called tetrahydrocannabinol (THC) -drug produces an intoxication that is mildly hallucinogenic
34
anadamide
- involved in the regulation of mood, memory, appetite, and pain perception - normally activates receptors in the brain (which is also what THC does) - some chemicals that mimic anadamide are found in dark chocolate for example
35
hypnosis
refers to a social interaction in which one person (the hypnotist) makes suggestions that lead to a change in another person's (the subject's) subjective experience of the world
36
posthypnotic amnesia
the failure to retrieve memories following hypnotic suggestions to forget
37
hypnotic analgesia
the reduction of pain through hypnosis in people are susceptible to hypnosis
38
3 key functions of memory
encoding, storage, and retrieval
39
memory
the ability to store and retrieve information over time
40
encoding
the process of transforming what we perceive, think, or feel into an enduring memory
41
storage
the process of maintaining information in memory over time
42
retrieval
the process of bringing to mind information that has previously encoded and stored
43
semantic encoding
the process of relating new information in a meaningful way to knowledge that is already stored in memory
44
during semantic judgement, the _____________ lobe of the brain is active.
lower left frontal lobe
45
During visual judgments, the _______________ lobe is active.
occipital
46
During organizational judgments, the ________________ is active.
upper left frontal lobe
47
visual imagery encoding
the process of storing new information by converting it into mental pictures
48
organizational encoding
the process of categorizing information according to the relationships among a series of items
49
survival encoding
draws on elements of semantic, visual imagery, and organizational encoding, which may give it an advantage over any one of the other three
50
sensory memory
type of storage that holds sensory information for a few seconds or less
51
2 types of sensory memory
iconic memory and echoic memory
52
iconic memory
a fast-decaying store of visual info
53
echoic memory
a fast-decaying store of auditory info
54
short-term memory
holds nonsensory info for more than a few seconds but less than a minute
55
rehearsal
process of keeping info in short-term memory by mentally repeating it
56
chunking
involves combining small pieces of info into larger clusters or chunks that are more easily held in short-term memory
57
working memory
refers to active maintenance of info in short-term storage - manipulates visual images or verbal info ex: contemplating your next move
58
long-term memory
type of storage that holds information for hours, days, weeks, or years
59
difference between short and long term memory
long term has no known capacity limits
60
anterograde amnesia
the inability to transfer new info from the short-term store to the long-term store
61
retrograde amnesia
the inability to retrieve information that was acquired on a particular date, usually the date of an injury or surgery
62
sights, sounds, smells, emotional content of a single memory are stored....
in the cortex
63
consolidation
the process by which memories become stable in the brain
64
REconsolidation
the process that causes memories to become vulnerable to disruption when they are recalled, thus requiring them to become consolidated again
65
long-term potentiation (LTP)
a process whereby communication across the synapse between neurons strengthens the connection- making further communication easier
66
state dependent retrieval
tendency for info to be better recalled when the person is in the same state (mood) during encoding and retrieval ex: happy mood when learning, happy when retrieving= more likely retrieving information
67
encoding specificity principle
states that a retrieval cue can serve as an effective reminder when it helps re-create the specific way in which info was initially encoded
68
retrieval cues
hints that help bring stored info to mind | ex: mc exams
69
explicit memory
occurs when people consciously or intentionally retrieve past experiences
70
implicit memory
occurs when past experiences influence behavior and performance, even without an effort to remember those experiences or an awareness of the recollection implicit= implied by our actions even though not consciously recalled
71
procedural memory
a type of implicit memory that refers to the gradual acquisition of skills as a result of practice -"knowing how" to do things
72
areas of the brain that are involved in procedural memory
brain regions outside the hippocampal area (including areas in the motor cortex)
73
semantic memory
type of explicit memory that refers consciously knowing facts and generally knowledge of the world
74
episodic memory
type of explicit memory that refers to consciously recalling personal experiences and EVENT (time and place)
75
priming
type of implicit memory that refers to enhanced ability to think of a stimulus, such as a word or an object, as a result of a recent exposure to a stimulus
76
area of the brain plays an important role in episodic memory
hippocampus- part of the medial temporal lobe
77
people who have amnesia are not able to retain...
explicit memory
78
transience
forgetting what occurs with the passage of time | -occurs during the storage phase of memory after an experience has been encoded and retrieved
79
retroactive interference
situations in which later learning impairs memory for information acquired later -ex: if you carry out the same activities at work each day, by the time Friday rolls around, it may be difficult to remember what you did on Monday because later activities blend in with earlier ones
80
proactive interference
refers to situations in which earlier learning impairs memory for information acquired later -ex: parking car in the same spot each day except for once, and that one time you forget where your car is!
81
absentmindedness
a lapse in attention that results in memory failure (lack of attention)
82
prospective memory
remembering to do things in the future
83
blocking
(tip-of-the-tongue) a failure to retrieve info that is available in memory even though you are trying to produce it
84
misattribution
assigning a recollection or an idea to the wrong source
85
suggestibility
the tendency to incorporate misleading information from external sources into personal recollections
86
bias
the distorting influences of present knowledge, beliefs, and feelings on recollection of previous experiences
87
persistence
the intrusive recollection of events that we wish we could forget
88
flashbulb memories
detailed recollections of when and where we heard about shocking events ex: remember when you heard about robin williams death?
