Document Summary
Describe the structure of modern intelligence tests: validity, reliability, discuss the type of information that can be extracted from intelligence tests. Introduce and evaluate the main claims of 3 theories of intelligence: g, multiple intelligences, triarchic theory, discuss how well the theories explain (un)intelligent behaviour. Most iq batteries (because made up of a number of smaller tests) consist of scales made up of subtests. A good test should have reliability and validity. Any test score consists of the true score plus error varobs = vartru + varerr. Error can be random or systematic varerr = vare + vars. Reliability tells us how much of the observed score reflects the true score (low error variance means a reliable score) Structure of intelligence tests varobs = vartru + varerr. ___________ r = vartru / varobs r = vartru / vartru + varerr. If varerr = 0, r = vartru / vartru + 0 r = 1.
