After an illness, N developed an unusual difficulty finding familiar routes. A psychologist investigated N for 12 months and collected the following information.
| Source | Month 1 | Month 12 |
|---|---|---|
| N's diary | "I usually need someone with me, even on familiar journeys." | "I can now complete several familiar journeys alone." |
| Interviews with N's brother | N often telephoned for help when travelling locally. | N rarely telephoned for help when travelling locally. |
| Familiar-route task | N completed 3 out of 10 routes without help. | N completed 8 out of 10 routes without help. |
The psychologist concluded that N's route-finding had improved and that the same pattern of improvement would occur in all adults with this difficulty.
Using the information, explain why the first conclusion is supported but the second conclusion is not justified.
