question 22

Multiple Choice

In a controlled experiment,Rosenthal and Jacobson (1968) informed grade school teachers that some of their students (called "bloomers") would show great academic improvement in the upcoming year.In reality,the "bloomers" were chosen randomly by the researchers,and were no smarter than any of the other students.Which of the following best describes the results of this study? At the end of the year,

• A) both bloomers and non-bloomers improved more on IQ tests than was expected.
• B) there were no IQ differences between bloomers and non-bloomers, but the bloomers were more interested in school.
• C) non-bloomers improved more on an IQ test than did bloomers.
• D) bloomers and non-bloomers performed equally well on an IQ test.
