logistics, creating strategy o Instituted first large-scale intelligence testing for army conscription to assign people to roles in the army Intelligence test can include many different types of tests o Vocabulary test – give definition of word o Digit span backward test – repeat digits in reverse order o Understanding relationship btwn concepts – asking how 2 things are alike o Using blocks to recreate a shape or picture while being timed If given to large number of people, people who tend to do well in one type of test tend to do well on other things All the tests have something in common – they are all normed o Normed – tests have been administered to really large numbers of people that you can compare any one person to a population (person performed some percentage better than people of their age) There are 2 major domains of intelligence – (1) crystallized intelligence (2) fluid intelligence o Crystallized intelligence – abilities that develop thru experience, schooling, knowledge from environment Includes vocabulary, knowing relationship between things o Fluid intelligence – ability to manipulate abstract information in your mind Includes solving a block puzzle to form a picture Fluid Intelligence Test Raven’s Progressive Matrices test – 12 puzzles that progressively increased in difficulty, test of fluid intelligence o Fluid intelligence – ability to reason abstractly and to solve novel problems o People w/ high fluid intelligence are good at solving puzzles and at logical reasonings Fluid intelligence tests don’t test content that is taught in educational context o Fluid intelligence is highest when an individual is in her 20s then decreases over time Raven’s score is NOT valid IQ score – valid intelligence test must be administered in standardized environment Who’s in the Expert’s Chair – Dr. Elliot Tucker-Drob Intelligence predicts performance in school and performance on the job o Some people worry ability of intelligence to predict performance is just an index of family background o Children who grow up in families w/ skills that are prized may give them an extra advantage Children who score higher on IQ tests than siblings do better on school and have better jobs

    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.
