Exam 11: Intelligence

A researcher administers a certain intelligence test to a large sample of adults. The test contains verbal, numerical, and spatial subtests. The researcher finds a correlation coefficient of .65 between verbal and numerical scores, a correlation coefficient of .75 between numerical and spatial scores, and a correlation of .55 between verbal and spatial scores. Do these data support the hierarchical model of intelligence? Why or why not?

Assume that, in general, reacting to a stimulus entails noticing the stimulus, then selecting the appropriate response depending on stimulus, then actually making the appropriate response. If this assumption is correct, which of the following sequences correctly orders simple reaction time, choice reaction time, and inspection time tasks with respect to the speed with which the average participant could complete them, from the most rapid to the slowest?

A researcher examines the verbal and math SAT scores of a large sample of young men and women. For each gender, she computes a statistic called the variance, a measure of the average distance of the scores from the group mean. Based on past research, what might she predict regarding the variance in scores for each gender?

Which of the following pairs of correlation coefficients most closely corresponds to the observed correlations between the intelligence scores of adopted children and those of their adoptive or biological parents?

Dr. O'Connor believes that intelligence comprises hierarchically arranged general and specialized abilities. He administers to a large sample of adults an intelligence test containing verbal, numerical, and spatial subtests. Which pattern of correlation coefficients is most consistent with Dr. O'Connor's view of intelligence?
