This experiment aims to investigate whether bilingualism protects against age related decline in executive function. Your literature review should include a brief overview of executive function and the Stroop task and theories concerning how executive function is affected by age and bilingualism. This background information should provide a rationale and foundation for the experiment. At the end of the introduction you should introduce your hypotheses based on the information you have provided earlier in the introduction. You must make your hypotheses specific and clear, you do not need to present them as a list.
