RESEARCH STUDY: Dr. Jones is interested in testing the 'midlife crisis' theory of personality development where it is theorized that people reach a 'midlife crisis' during their 40s and becomes increasingly self-centered (i.e., narcissistic). To test this theory, she conducted a study comparing the level of narcissism in adults in their 40's compared to individual in other developmental stages of their lives. Dr. Jones found no differences in narcissism between adults in their 40's than younger (or older) people. After this research, which of the following is not an example of scientists 'digging deeper' Select one: a. Speak to journalists about the importance of the midlife crisis b. Attempt the same study again to see if the results are replicated c. Use a different research design to test the same hypotheses d. Evaluate an alternative theory of midlife crisis
