1 Memory and Intelligence
Finding Nemo Ch. 8 & 9

2 Memory Memory Flashbulb Memory
persistence of learning over time through the storage and retrieval of information Flashbulb Memory a clear memory of an emotionally significant moment or event How Does Your Memory Work?

3 Memory Encoding Storage Retrieval
the processing of information into the memory system (extracting meaning) Storage the retention of encoded information over time Retrieval process of getting information out

4 Memory Short-Term Memory Long-Term Memory
activated memory that holds a few items briefly Long-Term Memory the relatively permanent and limitless storehouse of the memory system

5 Encoding Automatic Processing
unconscious encoding of incidental information space time frequency well-learned information word meanings we can learn automatic processing reading backwards

6 Encoding Effortful Processing Rehearsal
requires attention and conscious effort Rehearsal conscious repetition of information to maintain it in consciousness to encode it for storage

7 Encoding Imagery Mnemonics Chunking mental pictures
a powerful aid to effortful processing, especially when combined with semantic encoding Mnemonics memory aids (ROY G BIV) especially those techniques that use vivid imagery and organizational devices Chunking organizing items into familiar, manageable units use of acronyms HOMES--Huron, Ontario, Michigan, Erie, Superior

8 Storage: Long-Term Memory
How does storage work? Karl Lashley (1950) rats learn maze lesion cortex test memory Synaptic changes Long-term Potentiation Strong emotions make for stronger memories some stress hormones boost learning and retention

9 Storage: Long-Term Memory
Implicit vs. Explicit Memory Retention independent of conscious recollection vs. memory of facts and experiences Tasks requiring implicit memory Tasks requiring explicit memory mirror tracing recalling last year reading reversed text paired associate learning doing a word-completion task identifying the head of state singing part of a familiar song writing a term paper

10 Retrieval Recall Recognition
the person must retrieve information learned earlier as on a fill-in-the blank test Recognition the person has only to identify items previously learned as on a multiple-choice test

11 Retrieval Cues Deja Vu (French)--already seen
cues from the current situation may subconsciously trigger retrieval of an earlier similar experience "I've experienced this before."

12 Retrieval Cues Mood-congruent Memory State-dependent Memory
tendency to recall experiences that are consistent with one’s current mood memory, emotions, or moods serve as retrieval cues State-dependent Memory what is learned in one state (high, drunk, or depressed) can more easily be remembered when in same state

13 Forgetting Forgetting as encoding failure
Information never enters long-term memory External events Sensory memory Short- term Long- Attention Encoding failure leads to forgetting

14 Forgetting Interference Proactive (forward acting) Interference
disruptive effect of prior learning on recall of new information Retroactive (backwards acting) Interference disruptive effect of new learning on recall of old information

15 Forgetting Interference, cont. Motivated Forgetting Repression
people unknowingly revise memories Repression defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings, and memories Amnesia – loss of memory

16 Memory Construction We filter information and fill in missing pieces
Misinformation Effect incorporating misleading information into one's memory of an event Source Amnesia attributing to the wrong source an event that we experienced, heard about, read about, or imagined (misattribution)

17 Origins of Intelligence Testing
ability to learn from experience, solve problems, and use knowledge to adapt to new situations Mental Age a measure of intelligence test performance devised by Binet chronological age that most typically corresponds to a given level of performance Stanford-Binet IQ Test

18 Multiple Intelligences?
Social Intelligence the know-how involved in comprehending social situations and managing oneself successfully Emotional Intelligence ability to perceive, express, understand, and regulate emotions Howard Gardner (7 Intelligences) Visual-Spatial, Kinesthetic, Musical, Interpersonal, Intrapersonal, Linguistic, Logical-Mathematical

19 Assessing Intelligence
Wechsler Adult Intelligence Scale (WAIS) most widely used intelligence test subtests verbal and performance Aptitude Tests a test designed to predict a person’s future performance aptitude is the capacity to learn Achievement Tests a test designed to assess what a person has learned

20 Assessing Intelligence
Standardization defining meaningful scores by comparison with the performance of a pretested “standardization group” Normal Curve

21 Assessing Intelligence
Reliability the extent to which a test yields consistent results assessed by consistency of scores on: two halves of the test alternate forms of the test retesting Validity the extent to which a test measures or predicts what it is supposed to
