Intelligence is a person’s ability to learn and remember information, to recognize concepts and their relations, and to apply the information to their own behavior in an adaptive way. - differential approach favors the development of tests that identify and measure individual differences in people’s abilities to solve problems. It is uses to screen applicants to schools and candidates for jobs. - Developmental approach studies ways in which children learn to perceive, manipulate, and think about the world. - Information processing approach focuses on the types of skills people use to think and to solve various types of problems. Some intellectual ability may be independent of one another. Spearman proposed that a person’s performance on a test of intellectual ability is determined by two factors: the g factor (general factor) and the s factor (factor specific to a particular test). The g factor compromises of three qualitative principles of cognition. - Apprehension of experience : refers to the people’s ability to perceive and understand what they experience. - eduction of relations : refers to the ability to perceive the relation between lawyer and client. - eduction of corre lates: refers to the ability to apply a rule inferred from one case to a similar case. The correlation of unrelated and independent tests will be zero. The correlations among various tests of intellectual ability range from 0.30 to 0.70. Factor analysis: permits researchers to identify underlying commonalities among group of tests. Common factors are particular abilities that affect people’s performance on more than one test. A factor analysis determines which sets of tests forms groups. Factor analysis generates clues about the nature of intelligence; it doesn’t provide a theory of intelligence. The names given to the factors are up to the investigator and include a degree of subjective judgment. And it can never be more meaningful than the individual tests on which it is performed. To identify the relevant factors in human intelligence, one must include an extensive variety of tests in the factor analysis. WAIS is a useful predictor of scholastic performance and vocational success. Fluid intelligence is defined by relatively culture-free tasks, those that measure the ability to see relations among objects or the ability to see patterns in a repeating series of items.

Crystallized intelligence is defined by tasks that require people to have acquired information from their culture, vocabulary and information learned in school. Fluid intelligence is a person’s native capacity of intellectual performance, it represents a potential ability to learn and solve problems. Crystallized intelligence is what a person has accomplished through the use of his fluid intelligence or what he has learned. A person with high fluid intelligence exposed to an intellectually impoverished environment will develop a poor crystallized intelligence.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
