psych unit XI and VIII

intelligence

intelligence

the ability to learn from experience, solve problems, and use knowledge to adapt to new situations

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 a person's total score.

Charles Spearman

believed we have one general intelligence (g) that is at the heart of all out intelligent behavior

general intelligence (g)

according to Spearman and others, underlies all mental abilities and is therefore measured by every task on an intelligence test

L.L. Thurstone

identified seven clusters of primary abilities (word fluency, verbal comprehension, spatial ability, perceptual speed, numerical ability, inductive reasoning, and memory)

Howard Gardiner

identified eight relatively independent intelligences (Linguistic, Logical/Mathematical, Spatial, Bodily-Kinesthetic, Musical, Interpersonal, Intrapersonal, and Naturalist)

savant syndrome

a condition in which a person otherwise limited in mental ability has an exceptional specific skill, such as in computation or drawing

Robert Sternberg

agrees with Gardner, came up with Triarchic Theory (3 intelligences)

-analytical (problem-solving)

-creative intelligence

-practical intelligence

emotional intelligence

the ability to perceive, understand, manage, and use emotions

creativity

the ability to produce novel and valuable ideas

intelligence test

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

Alfred Binet

commissioned by the French government to design fair and unbiased intelligence tests to administer to the French schoolchildren

mental age

a measure of intelligence test designed by Binet; the level of performance typically associated with children of a certain chronological age

Lewis Terman

standford professor, modified Binet's tests for use as a numerical measure of inherited intelligence, adapting some of Binet's original items, adding others, and establishing new age norms, Terman extended the upper end of tests range from teenagers to "superior adults"

Flynn effect

people from 100 years ago would fail IQ tests today, whereas people today would get the highest scores on IQ tests from 100 years ago

Stanford-Binet

the widely used American revision (by Terman at Stanford University) of Binet's original intelligence test.

intelligence quotient (IQ)

IQ = mental age/chronological age x 100

-doesn't work for adults past puberty

aptitude test

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

-ACT/SAT

achievement test

a test designed to assess what a person has learned

-EOC

Wechler Adult Intelligence Scale (WAIS)

the WAIS and its companion versions for children are the most widely used intelligence tests; they contain verbal and performance (nonverbal) subtests

standardization

to make score meaningful, they are compared to a pretested sample population

normal curve

scores form a bell-shaped pattern call the "bell curve", most scores fall near the average, fewer and fewer near extremes

reliability

the test gives consistent scores no matter who takes it or when they take the test

validity

the test measures or predicts what it is supposed to

content validity

the extent to which a test samples the behavior that is of interest (it has what was promised on the test)

criterion

what it supposed to be on the test

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

cohort

crystalized intelligence

our accumulated knowledge and verbal skills; tends to increase with age

fluid intelligence

our ability to reason speedily and abstractly; tends to decrease during late adulthood

intellectual disability

a condition of limited mental ability, indicated by an intelligence score of 70 or below and difficulty in adapting to the demands of life; varies from mild to profound

down syndrome

a condition of mild to severe intellectual disability and associated physical disorders caused by an extra copy of chromosome 21 (trisomy 21)

heredity

the proportion of variation among individuals in a group that we can attribute to genes

-genetic influence explains about 50% of the observed variation among people

steryotype threat

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

motivation

(david mecclelland) a need or desire that energizes and directs behavior

instinct

a complex behavior that is rigidly patterned throughout a species and is unlearned

drive-reduction theory

we have a physiological need like hunger or thirst and actions satisfy the behavior are aroused

homeostasis

a tendency to maintain a balanced or constant internal state; the regulation of any aspect of body chemistry, such as blood glucose, around a particular level

incentive

positive or negative environmental stimuli that lure or repel us

hierarchy of needs

Maslow's pyramid of human needs, beginning at the base with physiological needs that must first be satisfied before higher-level safety needs and then psychological needs become active

Abraham Maslow

theorized that human needs are hierarchical, some have priority over others

Yerks-Dodson Law

we seek a certain level of arousal, if performing an easy task, you need stress added to do your best. Difficult tasks need to be done with no stress

-moderate arousal leads to optimal performance

glucose

the form of sugar that circulates in the blood and provides the major source of energy for body tissues. When its level is low, we feel hunger.

set point

the point (weight) at which your "weight thermostat" may be set (fixed)

basal metabolic rate

the body's resting rate of energy expenditure for maintaining basic body functions

anorexia nervosa

an eating disorder in which an irrational fear of weight gain leads people to starve themselves

bulimia nervosa

an eating disorder characterized by episodes of overeating, usually of high-calorie foods, followed by vomiting, laxative use, fasting, or excessive exercise

Alfred Kinsey

studied american sexology, known for proposing rational emotivitie behavior therapy to get people with dissatisfaction with sex to realize their life was not a failure

sexual response cycle

excitement, plateau, orgasm, resolution

refractory period

a resting period after orgasm, during which a man cannot achieve another orgasm

-men: lasts minutes to days

-women: a lot shorter

sexual disorder

a lack of desire for sex

estrogen

sex hormone that contributes to female sex characteristics and is secreted in greater amounts by females than by males

testosterone

both males and females have it, but the additional testosterone in males stimulates the growth of the male sex organs in the fetus and the development of the male sex characteristics during puberty

sexual orientation

what sex a person is attracted to

lateral hypothalamus

stimulates hunger, when removed, can't stimulate hunger
