Psyc 100 1st Edition Lecture 18Outline of Last Lecture I. What is intelligence?II. Can intelligence be measure? How?Outline of Current Lecture I. Measuring IntelligenceII. Constructing Intelligence TestsCurrent LectureModern Measures (2 basic types): Aptitude tests Used to predict future performance, ability to learn (WAIS, WISC) Achievement tests Used to measure what you have already learnedExamples:1. Wechsler tests of intelligence Wechsler Adult Intelligence Score (WAIS) Wechsler Intelligence Score for Children (WISC)Used to measure higher intelligence or determine if child has learning disabiltyGeneral components measured by lots of subtests: Verbal component Performance (non-verbal) componentThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Points: You get two component scores and one overall score Differences between component scores can illuminate learning disabilities2.

ReliabilityThe test must yield the same scores each time it is given to the same quantity. Split half Reliability Test retest Reliability3. ValidityThe test has to measure what it claims to be measuring Content validity- Does the test contain questions that directly assess the relevant behavior? Predictive validity- Can it predict what it is supposed to
