  1. Testing Methods • TM-09-16 Q1 • Researching human behaviour can be difficult. Why?

  2. The Hawthorne Effect

  3. Example – Hawthorne Effect • Hawthorne effect • The Hawthorne effect is a form of reactivity whereby subjects improve or modify an aspect of their behavior being experimentally measured simply in response to the fact that they are being studied, not in response to any particular experimental manipulation. • The term was coined in 1955 by Henry A. Landsberger when analysing older experiments from 1924-1932 at the Hawthorne Works (a Western Electric factory outside Chicago). Hawthorne Works had commissioned a study to see if its workers would become more productive in higher or lower levels of light. The workers' productivity seemed to improve when changes were made and slumped when the study was concluded. It was suggested that the productivity gain was due to the motivational effect of the interest being shown in them. Although illumination research of workplace lighting formed the basis of the Hawthorne effect, other changes such as maintaining clean work stations, clearing floors of obstacles, and even relocating workstations resulted in increased productivity for short periods. Thus the term is used to identify any type of short-lived increase in productivity.

  4. Six Methods of Observation • Testing method

  5. Testing Method • TM-09-16 Q2 • What do you think is an obvious problem with only relying on the testing method?

  6. Longitudinal Method • Group observation over a period of time

  7. Case-Study Method • In depth investigation of an individual or small group

  8. Cross-Sectional Method • Examines differences and similarities of demographic groupings

  9. Naturalistic Observation Method • Examines subjects in their natural environment

  10. Laboratory Observation Method • Examines participants in a lab setting

  11. TM-09-16 Q3 • TM-09-16 Q3 • Imagine that we as a research group wanted to test the efficacy of an advertising campaign targeting our students with the goal of having them make healthy eating choices at lunch time. Which method(s) would be best to employ and why?
