Q

What is elaboration?

A

Q

What was the basis behind the dual coding theory?

A

imagery faciliates memory because it provides a second kind of memory code and two codes are better than one

Q

What is dual-coding theory?

A

holds that memory is enhanced by forming both semantic and visual codes since either can lead to recall

Q

What is known about motivation to remember?

A

when motivation to remember is high at time of encoding, recall is better because it perceived to be more important

Q

What is sensory memory?

A

holds information in its original sensory form for a brief time
-allows the sensation of visual patter, sound or touch to linger for brief moment after the sensory stimulus is over

Q

How does information move from short term to long term memory?

A

rehearsal (repeating it over and over); without rehearsal information in short-term is lost in 10-20 seconds

25
What type of memories suggest that long-term memories might be permanant?
flashbulb memories
26
What is a flashbulb memory?
unusually vivid and detailed recollections of momentous events -when people do forget its based of retrival failure but there is no convincing evidence that supports this
27
What is the tip of the tongue ?
The temporary inability to remember something you know, accompanied by a feeling that it’s just out of reach
28
What are retrieval cues ?
things that help a person to remember a certain memory
29
What is used sometimes in eyewitness recall of legal investigations
hypnosis
30
What is true of our reconstructions of memories?
they are reconstructions of the past and may be distorted and may include details that did not actually happen
31
What is the misinformation?
participants recall of an event they witnessed is altered by introducing misleading post information -it can distort recall of basic true events
32
What is source monitoring?
process of making inferences about the origins of memories (misinformation effect appears to be due to unreliability of source monitoring)
33
What is true of the source of memories?
people decide at the time of retrieval where memories come form
34
What is a source-monitoring error?
when memory from one source is attributed to another source
35
What is ineffective encoding?
when you never encoded the memory correctly in the first place
36
What is psuedoforgetting?
phenomenon of thinking you forgot something that you never really learned -usually attributed to lack of attention
37
What is decay theory?
The idea that forgetting occurs because memory traces fade with time
38
What is interference theory?
people forget information because of competition from other mateiral
39
What is retroactive interference?
occurs when new information impairs the retention of previously learned information
40
What is proactive interference?
occurs when perviously learned information interferes with the retention of new information
41
What is encoding specificity principle ?
states that the value of a retrieval cue depends on how well it corresponds to the memory code
42
What is true about language aquisition?
language is a species-specific behavior, seems to be localized in the brain -– Listening to speech is associated with greater electrical activity in the left hemisphere than rightq
43
What is aphasia?
an acquired communication disorder that impairs a person’s ability to process language, but does not affect intelligence
44
What type of theory for language did Skinner propose?
behaviorist theory; children learn language through imitation, reinforcement and other principles of conditioning
45
What is the Nativst approach by Noam Chomsky?
human have language acquisition device (LAD) that is an innate mechanism or process that facilitates the learning of language -humans learn language in the same way that birds learn to fly
46
What three levels of analysis can intelligence be decribed as?
As consisting of one thing As consisting of a few things As consisting of many things
47
What is the germinal stage ?
fertilized zygote; the first 2 weeks after conception
48
What is the embryonic stage?
2 weeks-8 week
49
What time fetal stage?
9th week until birth
50
What did Freud say about defense mechanisms as they relate to the id ego and superego?
Saw behavior as conflict between the id ego and superego with conflicts on sex and aggressive impulses having far reaching consequences
51
Why do we have defense mechanisms according to Freud?
conflicts in life cause us anxiety so we have defense mechanism s
52
What are some of the defense mechanisms suggested by Freud?
repression, projection, displacement, reaction formation, regression, rationalization, identification, sublimation
53
What did Jean Piaget say about cognitive development?
it comes from the interaction of environment and maturation
54
What two things did Jean paiget say cognitive development depends on?
assimilation and accommodation
55
What is assimilation?
when individual interprets new info in terms of existing mental structures
56
What is the last part of the brain to develop?
prefrontal cortex
57
What is true of the white matter in the brain?
the white matter increases myelinization and increased synaptic pruning
58
What is the Bayley Scale of Infant development ?
a test given to infant to tests for developmental issues
59
What are the WISC and WAIS used for?
to test the intelligence of children and adult and broken up in to a verbal and performance portion
60
What is true overall about the iq scores of boys and girls?
on average they score similarly
61
What areas of IQ do girls typically perform better in?
writing, perceptual speed, and verbal fluency
62
What areas of IQ do boys typically perform better in?
visual-spatial processing, science, and math problem solving
63
What does Skinner say about language development?
reinforcement can explain language development
64
What does Bandura say about language development?
learning language occurs through observation -kids imitate what their kids say and generalization
