Psychology Exam 3 Flashcards
Intelligence
the ability to learn from experience, solve problems, and use knowledge to adapt to new situations.
Spearman’s general intelligence (g)
Charles Spearman believed that we have one general intelligence that underlies all mental abilities.
a person who is able to solve more questions on an aptitude test has a higher intelligence when compared to a person who is able to solve lesser questions
He noted that those who score high in one area typically score high in other areas as well.
General intelligence (g) according to Spearman and others, underlies all mental abilities and is therefore
measured by every task on an intelligence test.
Cattell-Horn-Carroll Theory: (GHC)
This theory affirmed a general intellectual ability factor. It affirmed the existence of Gf and Gc And it identified more specific abilities, such as reading and writing ability, memory capacity, and processing speed
The CHC theory continues to influence psychologists, because it recognizes that many abilities comprise intelligence, but that these specific abilities exist under a broader umbrella of general intelligence.
fluid intelligence
our ability to reason speedily and abstractly, as when solving novel logic problems—decreases beginning in the twenties and thirties, slowly up to age 75 or so, then more rapidly, especially after age 85
crystallized intelligence
ouraccumulated knowledge and verbal skills
•Tends to increase with age
Crystallized intelligence (Gc)—
our accumulated knowledge as reflected in vocabulary and analogies tests—increases up to old age.
Gardner’s multiple intelligence theory
Howard Gardner proposed eight relatively independent intelligences
(linguistic, logical-mathematical, musical, spatial, bodilykinesthetic,
intrapersonal, interpersonal, and naturalist), as well as
a possible ninth (existential intelligence)
Brain damage, for example, may destroy ones ability but leave others intact.
Interpersonal
Intrapersonal
Bodily-kinesthetic
naturalistic
math
music
spatial
linguistics
*existential
Sternberg’s 3 intelligences
Creative: (trailblazing smarts) ability to generate novel ideas
Analytical: (school smarts) traditional academic problem-solving
Practical: (street smarts) skill at handling everyday tasks
Emotional intelligence
the ability to perceive, use, understand, manage, and handle emotions in positive ways to relieve stress, communicate effectively, empathize with others, overcome challenges and defuse conflict.
Achievement tests
which are intended to reflect what you have learned. Your final exam will measure what you learned in this class.
aptitude tests
which are intended to predict what you will be
able to learn. If you took an entrance exam, it was designed to predict your ability to do college or university work.
Intelligence assessments:
An intelligence test assesses an individual’s mental aptitudes and compares them with those of others, using numerical scores
Stanford-Binet
**the widely used American revision (by Terman at Stanford University) of Binet’s original
intelligence test
Alfred Binet who tended toward an environmental explanation of intelligence differences, started the modern intelligence-testing movement in France in the early 1900s when he developed questions to help predict children’s future progress in the Paris school system. Binet hoped that determining the child’s mental age (the age that typically corresponds to a certain level of performance) would help identify appropriate school placements. Binet hoped his test, which measured children’s mental age, would improve their education but feared it might also be used to label children.
During the early twentieth century,Lewis Terman of
Stanford University revised Binet’s work for use in the United States
Terman thought his “Stanford”-Binet could help guide people toward appropriate opportunities, but his belief in an intelligence that was fixed at birth and differed among ethnic groups realized Binet’s fear that intelligence tests would be used to limit children’s opportunities.
WAIS
Wechsler Adult Intelligence Scale
The most widely used intelligence tests today
are the Wechsler Adult Intelligence Scale (WAIS) and Wechsler’s test for children. These tests differ from their predecessors in the way they offer an overall intelligence score as well as scores for verbal comprehension, perceptual reasoning, working memory, and
processing speed.
WISC
Wechsler Intelligence Scale for Children
Psychologist David Wechsler created what is now the most widely used individual intelligence test, the Wechsler Adult Intelligence Scale (WAIS),
together with a version for school-age children (the
Wechsler Intelligence Scale for Children [WISC]), and another for preschool children.
Intelligence quotient
IQ tests : defined originally as the ratio of mental age (ma) to chronological age (ca) multiplied by
100 (thus, IQ = ma/ca × 100). On contemporary intelligence tests, the average
performance for a given age is assigned a score of 100.
Standardization
**defining uniform testing procedures and meaningful scores by comparison with the performance of a pretested group
The number of questions you answer correctly on an intelligence test would reveal almost nothing. To know how well you performed, you would need some basis for comparison. That’s why test-makers give new tests to a representative sample of people. The scores from this pretested group become the basis for future comparisons. If you then take the test following the same procedures, your score will be meaningful when compared with others. This process is called standardization.
Reliability vs. validity
For a test to be reliable, it also needs to be valid. For example, if your scale is off by 5 lbs, it reads your weight every day with an excess of 5lbs. The scale is reliable because it consistently reports the same weight every day, but it is not valid because it adds 5lbs to your true weight.
reliability
consistent results (on two halves of the test on alternative forms of the test, or on retesting)is the extent to which a test yields consistent results
validity
Is the extent to which a test measures or predicts what it is supposed to A test has predictive validity if it predicts a behavior it was designed to predict**
it is assessed by computing the correlation between test scores and the criterion behavior
A test’s validity is established in reference to a specific purpose; the test may not be valid for different purposes. For example, the test you use to make valid predictions about someone’s technical proficiency on the job may not be valid for predicting his or her leadership skills or absenteeism rate
Intellectual disability
neurological developmental disorder that is
apparent before age 18 sometimes with a known physical cause…test score of 70 or below
The common types of intellectual disabilities include
Autism
Down syndrome
Fragile x syndrome
Fetal alcohol syndrome
Prader-Willi syndrome : A genetic disorder that causes obesity, intellectual disability, and shortness in height.

interpretations.
