Behavioral performances on the tool tasks
| Task | Healthy subjects |
Patients |
|
|---|---|---|---|
| Raw score | Raw score | Corrected t score | |
| Tool use | 6.58 (0.23) | 5.71 (0.80) | −4.04 (3.85) |
| Tool concept | |||
| Oral picture naming | 98% (3%) | 74% (32%) | −8.44 (10.83) |
| Picture associative matching | 96% (6%) | 87% (14%) | −1.47 (2.13) |
| Word associative matching | 96% (6%) | 87% (15%) | −1.21 (2.34) |
Raw score for tool use was the mean 7-point-scale rating value; for tool concepts, it was the mean accuracy on each task. The corrected t score of patients reflected the degree of behavioral deficits by taking into consideration the performance of healthy subjects. Numbers in parentheses are SD.
