1
New cards
Intelligence test

A method for assessing an individual's mental aptitudes and comparing them with those of others, using numerical scores.

2
New cards
Mental age

A measure of intelligence test performance devised by Binet; the chronological age that most typically corresponds to a given level of performance.

3
New cards
Chronological age

The precise number of years that a person has lived, calculated from their date of birth.

4
New cards
Intelligence Quotient (IQ)

Defined originally as the ratio of mental age (ma) to chronological age (ca) multiplied by 100 units (thus, IQ= ma/ca x 100). On contemporary tests, the average performance for a given age is a score of 100.

5
New cards
Intelligence

Mental quality consists of the ability to learn from experience, solve problems, and use knowledge to adapt to new situations.

6
New cards
Factor analysis

A statistical procedure that identifies clusters of related items (called factors) on a test; used to identify different dimensions of performance that underlie one's total score.

7
New cards
General intelligence (g)

A general intelligence factor that Spearman and others believed underlies specific mental abilities and is therefore measured by every task on an intelligence test.

8
New cards
Multiple Abilities (g theory)

A psychological theory that states that people have different ways of learning and different types of intelligence

9
New cards
Creativity

The ability to produce novel and valuable ideas.

10
New cards
Aptitude test

A test designed to predict a person's future performance; aptitude is the capacity to learn.

11
New cards
Achievement test

A test designed to assess what a person has learned.

12
New cards
Flynn effect

A generational phenomenon in which average Intelligence Quotient (IQ) scores have been found to increase across time in developed countries at a startlingly consistent rate of approximately 0.33 points per year, or 3.3 points per decade

13
New cards
Standardization

Defining meaningful scores by comparison with the performance of a pretested "standardization group".

14
New cards
Psychometric

A field of study within psychology concerned with the theory and technique of measurement. Generally covers specialized fields within psychology and education devoted to testing, measurement, assessment, and related activities.

15
New cards
Norming

The process of establishing a standard or reference point for a particular measurement or assessment.

16
New cards
Percentile rank

The percentage of individuals in a given population who score lower than or equal to a specific value. It indicates the relative position of a score within a distribution

17
New cards
Reliability

A measure of how well a psychological test or assessment accurately reflects the theoretical construct it is designed to measure.

18
New cards
Test-retest reliability

A way to measure the internal consistency of a test, survey, or other instrument. It's a type of internal consistency reliability that assesses how well a test measures the same variable.

19
New cards
Split-half reliability

The extent to which a test yields consistent results, as assessed by the consistency of scores on two halves of the test, on alternate forms of the test, or on retesting.

20
New cards
Validity

The extent to which a test measures or predicts what it is supposed to.

21
New cards
Constructive validity

A measure of how well a psychological test or assessment accurately reflects the theoretical construct it is designed to measure.

22
New cards
Predictive validity

The success with which a test predicts the behavior it is designed to predict; it is assessed by computing the correlation between test scores and the criterion behavior. (also called criterion-related validity).

23
New cards
Fixed mindset

The view that intelligence, abilities, and talents are unchangeable, even with effort.

24
New cards
Growth mindset

A focus on learning and growing rather than viewing abilities as fixed.

25
New cards
Stereotype threat

A self-confirming concern that one will be evaluated based on a negative stereotype.

26
New cards
Stereotype lift

A phenomenon in psychology where individuals from a group that is not typically stereotyped in a negative way perform better on a task when they are aware of a negative stereotype about another group.

27
New cards
Concept

A mental grouping of similar objects, events, ideas, or people.

28
New cards
Prototype

A mental image or best example of a category. Matching new items to the prototype provides a quick and easy method for including items in a category.

29
New cards
Assimilation

Interpreting our new experiences in terms of our existing schemas

30
New cards
Accommodation

Adapting our current schemas to incorporate new information.

31
New cards
Algorithm

A methodical, logical rule or procedure that guarantees solving a particular problem.

32
New cards
Heuristic

A simple thinking strategy that often allows us to make judgments and solve problems efficiently; usually speedier but also more error-prone than algorithms.

33
New cards
Mental Set

A tendency to approach a problem in a particular way, especially a way that has been successful in the past but may or may not be helpful in solving a new problem.

34
New cards
Functional Fixedness

The tendency to think of things only in terms of their usual functions; an impediment to problem solving.

35
New cards
Representativeness Heuristic

Judging the likelihood of things in terms of how well they seem to represent, or match, particular prototypes; may lead one to ignore other relevant information. (sterotypes) 

36
New cards
Availability Heuristic

Estimating the likelihood of events based on their availability in memory; if instances come readily to mind (perhaps because of their vividness). We presume such events are common. (seen on the news)

37
New cards
Schema

A concept or framework that organizes and interprets information.

38
New cards
Creativity

The ability to produce new & valuable ideas

39
New cards
Convergent thinking

Narrowing the available problem solutions to determine the single best solution

40
New cards
Divergent thinking

Expanding the number of possible problem solutions; creative thinking that diverges in different directions

41
New cards
Gambler’s Fallacy

A cognitive bias that occurs when someone believes that a past event will impact the outcome of a future event.

42
New cards
Sunk-Cost Fallacy

The cognitive bias where people tend to continue investing time, money, or effort into something even when it is no longer beneficial because they've already invested significantly in it, essentially feeling like they can't "waste" what they've already put in, regardless of future potential gains or losses.

43
New cards
Executive Functions

Higher-level cognitive skills that help people manage their thoughts and actions.
