Psychologist Edwin Boring
answer
who said that intelligence is whatever intelligence tests measure? (but is not very useful
question
Intelligence is the by-product of sensory capacity. He reasoned that most knowledge first comes through the senses, especially vision and hearing. Therefore, he assumed, people with superior sensory capacities, like better eyesight, should acquire more knowledge than will other people.

question
psychologist Charles Spearman
answer
the phenomenon of positive correlations among intelligence test items caught the attention of who??
question
The development of G and S -G: general intelligence: all intelligence test items are positively correlated because they reflect the influence of overall intelligence, spearman wasn't sure what produces individual differences in g, but speculated that it has something to do with "mental energy" -for Spearman ,g corresponds to the strength of our mental engines -g is exceddingly controversial becasue it implies that some people are just plain smarter than others
answer
this lead to what??
question
-s: specific abilities that is unique to each item -according to Spearman, how well we perform on a given mental task depends not only on our general smarts (g), but also on our particular skills in narrow domains (s).
answer
Spearman also proposed the existence of a factor called s:
question
General intelligence -accounts for overall differences in intellect among people
answer
G:
question
Specific abilities -each individual's particular skills

S:
question

question
entirely different domains of intellectual skill -the concept of g is wrong, or at least incomplete -we can't simply say that Sally is smarter than bill, because there are many ways of being smart -Spearman's concept of S is a partial acknowledgement of the existence of multiple intelligences, because tit recognized that people with equal levels of g can have different intellectual strengths and weaknesses.
answer
multiple intelligneces

answer
triarchic model...?
question
1. analytical intelligence: the ability to reason logically, "book smarts" the kind of intelligence we need to do well on traditional IQ tests and college admission exams, the form of intelligence most closely related to g, for Sternberg, only one component of intelligence and not necessarily the most crucial 2. practical intelligence, also called "tacit intelligence" the ability to solve real world problems, especially those involving other people, contrasts analytical intelligence, the form of "street smarts" the kind of smarts we need to "size up" people we've just met, or figure out how to get ahead on the job, also relates to social intelligence (the capacity to understand others 3. Creative intelligence: also called "creativity" our ability to come up with novel and effective answers to questions, kind of intelligence we need to find new and effective solutions to problems like composing an emotionally moving poem or exquisite piece of music, sternberg argues that practical and creative intelligences predict outcomes, like job performance, that analytical intelligence doesn't

question
-Arthur Jensen studied a group of families in an extremely poor area of rural Georgia. FOr African-American (but not Caucasian) children, he found evidence for cumulative declines, that is, differences that increase over time. Older siblings consistently lhad lower IQs than did younger siblings, with a steady decrease of about 1.5 IQ points per year. Jensen's explanation was that siblings in this impoverished region experienced progressively more intellectual deprivation as they aged, leading them to fall further behind other children.

Flynn Effect:
question
