1 / 53

54 Terms

1

Echoic memory

Auditory stimulation

New cards
2

Ionic memory

Visual stimulation

New cards
3

Short term memory

The place where we sort and encode information before transferring it to long term memory

New cards
4

Long term memory

Essentially all of your knowledge of yourself and the world around you

New cards
5

Implicit bias

If it can affect behavior or mental processes without fully conscious (knowing how)

New cards
6

Explicit memory

Always involve consciousness (knowing what)

New cards
7

Attention

The brains ability to focus on stimuli

New cards
8

Encoding

The modification of information to fit the preferred format for the memory

New cards
9

Storage

The retention of encoded material over time

New cards
10

Retrieval

The locating and recovering of information from memory

New cards
11

Role of sleep in memory

Memory is encoded during REM sleep, the hippocampus processes memories for later retrieval

New cards
12

Retroactive interference

When a new memory blocks the retrieval of an old memory

New cards
13

Proactive interference

When an old memory disrupts the learning and remembering of a new memory

New cards
14

Distributed practice

A learning procedure in which practice periods for a particular task are separate by rest periods

New cards
15

Chunking

Creating memory patterns or meaningful unit of memory

New cards
16

Mnemonics

Memory aids, especially those techniques that use visual imagery and organizational devices

New cards
17

Semantic encoding

Encoding of memory, including meaning of words (Pi story)

New cards
18

Retrieval cues

Search terms we use to activate

New cards
19

Serial position effect

Tendency to recall last terms in a list the best

New cards
20

Mood-Congruent memory

A theory which says we tend to selectively remember memories that match (are congruent with) our mood

New cards
21

Memory construction

We often construct our memories as we encode them, and we may also alter our memories as we withdraw them

New cards
22

“Forgetting curve” (Herman Ebbinghaus)

People tend to continually halve their memory of newly learned knowledge in a matter of days or weeks unless they actively review the learned material

New cards
23

Absent-mindedness

Forgetting caused by lapse in attention

New cards
24

Source amnesia

Attributing to the wrong source an even we have experienced, heard about, read about, or imagined

New cards
25

Anterograde amnesia

Loss of the ability to create new memories after the event that caused the amnesia

New cards
26

Retrograde amnesia

Unable to recall events that occurred before the development of amnesia

New cards
27

Infantile amnesia

The inability of adults to recollect early episodic memories

New cards
28

Neon Chomsky

Argues that children’s readiness to learn language is a preprogrammed step to acquire language

New cards
29

Phoneme

In a spoken language, the smallest distinctive sound unit

New cards
30

Morpheme

In a language, the smallest unit that carries meaning

New cards
31

Syntax

Grammar rules for combing words into sensible sentences in a given language

New cards
32

Critical period

The time during which a given behavior is especially susceptible to, and indeed requires specific environmental influences to develop normally

New cards
33

Telegraphic speech

Early speed stage in which the child speaks like a telegram (“go car”) using mostly bounds and verbs, omitting “auxiliary” words

New cards
34

Spearman’s G Factor

Linked to many fosters that can be analyzed by factor analysis

New cards
35

Howard Gardner’s theory of intelligence

Proposes eight types of intelligences and speculates a ninth one -existential intelligence

New cards
36

Stern berg’s theory of intelligence

Proposes three intelligences rather than eight, analytical intelligence, creative intelligence, practical intelligence

New cards
37

Standardized Test

Administering the test to a representative sample of future test takers in order to establish a basis for meaningful comparison

New cards
38

Validity

How well a test measures what it has been designed to measure, reliability is the ability to consistently find similar results

New cards
39

Recall

When one must reproduce previously presented material (Police sketch)

New cards
40

Recognition

When one must identify information that is provided, which was previously presented

New cards
41

Parallel processing

Processing of servers aspects of a problem simultaneously (motion, depth, color, and form)

New cards
42

Long term potentiation

An increase in a cells firing potential after brief, rapid stimulation. Believed to be a neural basis for learning and memory

New cards
43

Algorithm

Problem solving procedures or formulas that guarantee a correct outcome if correctly applied

New cards
44

Heuristic

Simple, basic rules that serve as shortcuts to solve complex mental tasks

New cards
45

Confirmation bias

Tendency to search for information that confirms one’s preconceptions

New cards
46

Belief perseverance

Clinging to one’s intials conceptions after the basis on which they formed has been discredited

New cards
47

Convergent thinking

More logical and has the goal of arriving at a “correct answer”

Involves exploring many possible solutions, spontaneous, unorganized thought

New cards
49

A mental image or best example of a category, formed on the basis of frequently experienced features

New cards
50

Mental set

Tendency to approach a problem in a particular wah

New cards
51

Priming

Triggers a thread of associations that bring us to a concept

New cards
52

Framing

The way an issue is posed

New cards
53

Crystallized intelligence

What we know from experience, culture, learning and education, used when we try to solve problems we’ve seen before

New cards
54

Fluid

Raw processing speed, mental quickness, and abstract reasoning, used to solve problems we haven’t seen before
