A psychologist carries out a case study of P, an adult with a rare communication condition. The psychologist is considering the conclusion that P can understand spoken instructions accurately in all settings.
| Method | Finding |
|---|---|
| Interview with P | P says, "I nearly always understand what people ask me to do." |
| Observation at P's home | P completes 9 out of 10 familiar spoken instructions without help. |
| Psychological task in a quiet room | P correctly follows 4 out of 10 unfamiliar spoken instructions. |
Explain how the findings from the three methods should affect the psychologist's confidence in this conclusion.
