27. (p. 263) Helen is conducting an experiment to determine how temperatures affect the productivity of
employees. She has just completed the first phase of her experiment, in which she had a group of employees
perform job related tasks in a special room where the temperature was 10 degrees cooler than on the factory
floor. The employees in the experimental group consistently outperformed employees in the factory. The
Hawthorne effect suggests that the most likely reason for this improvement in performance is that the cooler
working conditions allowed the employees in the experiment to work harder without getting tired.
28. (p. 263) Hal is a small business owner who wants to find a way to increase the productivity of his employees.
He has just finished reading a book on worker motivation, and found the book’s discussion of the Hawthorne
studies particularly relevant. Based on his reading, Hal is likely to view pay increases as the best way to
improve employee motivation.
