MANAGERIAL APPLICATION Imagine that you work for the Consumers Union, the consumer protection organization that publishes Consumer Reports. Your supervisor asked you to test the effectiveness of several subliminal self-help CDs that are currently on the market. Before designing your experiment, you performed a literature review and found a classic experiment on the effectiveness of subliminal self-help audiotapes. Students were randomly assigned to conditions in a 2 X 2 fac- torial design in which expectations and audiotape contents were manipulated experimentally." Half the students were told that the audiotape improved memory performance. The other half were told that the audiotape improved self-esteem. Half of the students received the memory audio- tape, and half received the self-esteem audiotape, regardless of what they were told earlier. Hence, in half of the conditions, expectations and content matched (e.g., students expected the audiotape to improve memory and the audiotape was supposed to actually improve memory). For the remaining half, expectations and content were mismatched (e.g., students expected the audiotape to improve memory, but the audiotape was supposed to actu- ally improve self-esteem). The results showed that expectations influenced memory performance and self-esteem ratings and that the content of the audiotapes had no effect. Imagine that you conduct ed a replication experiment using currency subliminal self-help CDs and that you obtained same pattern of results. "g currently available YOUR CHALLENGE: 1. Explain your results. Which of the seven sins of memory is at work here and how is it operating? 2. Placebo effects are common in medical research. Which of the seven sins of memory is responsible for placebo effects? How do medical researchers design experiments to test for placebo effects 3. How are marketing expectation effects and medical placebo effects similar? 4. How would you protect consumers from subliminal self-help CDs that don't work
