Suppose a single random sample of workers in a factory is exposed to five different reward systems in succession, with each system being used for one month. What is the name of the threat that reminds researchers that the research results for the last reward system may not generalize to the population of workers?

Multiple-treatment interference occurs when the effects of one treatment carry over and affect the results of subsequent treatments. In this scenario, the effects of the previous reward systems may carry over and affect the results of the last reward system, making it difficult to generalize the results to the population of workers. The other options (reactive effect of experimental setting, reactive effect of testing, and selection bias) refer to different threats to internal validity that are not applicable to this scenario.
