Deck 9: A: Intelligence and Iq Testing

Question 1

Describe why standardized tests such as the SAT and GRE are not strong predictors of grades in college or graduate school?

Answer 1

Many intervening variables influence grades besides standardized test scores.
Variables such as work ethic,achievement motivation,amount of time studying,quality of teaching,subject matter rigour,program rigour,and the reliability and validity of classroom tests and assessments used to calculate one's grade can all influence overall correlations between SATs and GPA for example.Given all the variables that could influence one's GPA,standardized tests should not be expected to do well in predicting GPAs over a four-year period.SATs,which focus on math and verbal skills,may be stronger predictors of GPAs for students taking math and English courses during their first year of college.

Question 2

In your estimation,which subtests of the WAIS do you believe are most significantly environmentally influenced?

Answer 2

Scores on the information and vocabulary section are likely the result of schooling and exposure to certain information through upbringing.Scores on the comprehension section are likely linked to familiarity with the social norms,traditions,and morals of those writing IQ test items.

Question 3

Which subtests of the WAIS do you believe are most significantly genetically influenced?

Answer 3

Performance scale items including digit symbol,picture completion,block design,picture arrangement,and object assembly could be linked to genetics in cases that involve visual impairments,perceptual deficiencies,or motor skill delays.
