Summary
These lecture notes detail different types of intelligence tests, such as the Stanford-Binet and Ravens Progressive Matrices. They cover topics like testing procedures, scoring, and the structure of intelligence. The document also explores general intelligence factor, Spearman's g, and Thurstone's primary mental abilities.

# 10/10 W10 Lecture 3 ## Intelligence Tests ### Stanford-Binet (TV edition) Jauks IQ with four categories of testing: 1. Verbal reasoning 2. Abstract/visual reasoning (timed) 3. Quantitative reasoning 4. Short-term memory (remembering visuals in order) - Standard age score (SAS) of 100, SD = 16 - Standard materials include various printed and intractable things. - Examiner must be highly trained. *Clinicians use these as well for observations* *Tests are multiple each with harder difficulty* *Test intermixed to avoid boredom, each 30-90 minutes* ### General IQ test process: 1. Establish a basal and ceiling level for each task - Usually start at a point suggested by examinee age. - Basal level = 4 items passed in a row. - Ceiling level = 3 or more at of 4 consecutive items failed. 2. Scoring: each response is recorded verbatim, and Pass/Full is given to each item according to strict guidelines 3. Raw score = # of correct items. - Score later converted to a scaled Score ### Group testing: Ravens progressive Matrices - Prototype test of fluid intelligence (GAF) - Depends minimally on learning and acculturation ### How can we infer the structure of intelligence? 1. Examine correlation patterns - How different scores move together. - Helps single out different or same ability. 2. Factor analysis of intelligence in a correlation matrix - Positive manifest: every single result is positively correlated with all other results, implying there is something dearly that correlation. - Clustering correlations at various levels could reveal different driving factors of intelligence. ### General intelligence factor: Spearman's g - Thurstone's primary mental abilities: 21 intelligence - When there are a few (or simply >1) mental abilities driving different levels of intelligence test correlation. *There can also be hybrid assumptions - combination of the two.*
