Demographics, Psychological Functioning, and Neuropsychological Test Scores (mean ± SD) in TD and WS groups in Study 1
| TD (n = 13) | WS (n = 19) | Difference | |
|---|---|---|---|
| Age (years) | 27.1 ± 3.6 | 27.8 ± 6.4 | t30 = .381, p = .706 |
| Sex (% male) | 38.5 | 52.6 | χ2 = .622, p = .430 |
| BDI-II | 2.8 ± 2.9 | 3.5 ± 4.1 | t30 = −.574, p = .570 |
| BAI | 3.2 ± 3.9 | 7.7 ±7.3 | t30 = 1.969, p = .058, d = 0.7 |
| K-BIT IQ | 115.4 ± 14.0 | 67.4 ± 13.8 | t30 = −9.585, p < .001, d = 3.5 |
| VMI [Age Equivalence (years)]a | 15.7 ± 3.3 | 5.6 ± 0.8 | U = 0.00, p < .001, d = 4.6 |
| Grooved Pegboard [time (s)]a,b | 122.2 ± 10.5 | 334.2 ± 37.9 | U = 0.00, p < .001, d = 7.0 |
BDI-II = Beck Depression Inventory-II
BAI = Beck Anxiety Inventory
VMI = Visual Motor Integration, 4th edition
a
Non-parametric statistics (Mann-Whitney U) used due to non-normality.
b
Due to concerns that allowing participants to complete the Grooved Pegboard would result in very different time durations for the neuropsychological battery for TD and WS participants, individuals were limited to 180 seconds per side on this task.
