Means and Effect Sizes for Selected Variables From Experiment 2 for Non-Exposed Control (CON) and Alcohol-Exposed (ALC) Groups
| Variable | CON M (SD) | ALC M (SD) | ESa | F | p |
|---|---|---|---|---|---|
| Confirmed correct verbal | 9.41 (2.50) | 8.91 (3.72) | 0.16 | 0.23 | 0.64 |
| Confirmed correct perceptual | 10.82 (1.74) | 7.04 (3.47) | 1.38 | 16.93 | <0.001 |
| Percent accuracy sorting | 8.88 (2.42) | 6.04 (3.84) | 0.88 | 7.15 | 0.01 |
| Percent accuracy description | 9.06 (2.41) | 6.17 (3.74) | 0.92 | 7.72 | 0.008 |
| Repeated sorts | 2.76 (1.75) | 4.61 (3.43) | 0.68 | 4.09 | 0.05 |
| Set loss errors | 0.00 (0.00) | 0.22 (0.67) | 0.46 | 1.77 | 0.19 |
| Nontarget even sort | 0.53 (0.94) | 0.96 (1.11) | 0.42 | 1.65 | 0.21 |
| Repeated descriptions / free | 1.06 (1.56) | 3.48 (4.56) | 0.71 | 4.38 | 0.04 |
| Incorrect description / free | 1.76 (1.89) | 6.00 (5.28) | 1.07 | 9.93 | 0.003 |
| Structured description score | 9.00 (2.45) | 5.22 (3.49) | 1.25 | 14.60 | <0.001 |
| Incorrect description / structured | 3.18 (3.66) | 7.74 (5.11) | 1.03 | 9.80 | 0.003 |
| Repeated description / structured | 1.29 (1.76) | 5.00 (4.48) | 1.09 | 10.38 | 0.003 |
| CST compositeb | 97.18 (6.06) | 83.39 (14.92) | 1.21 | 12.86 | 0.001 |
| FSIQ–CST | 13.59 (13.24) | 1.83 (11.78) | 0.94 | 8.77 | 0.005 |
All scores except the FSIQ–CST difference score and error scores are scaled scores with a mean of 10 and a standard deviation of 3. Scaled scores were converted to standard scores to calculate the CST composite. Error scores are presented as raw scores.
Effect sizes are Cohen’s d with small effects > 0.2, medium effects > 0.5, and large effects > 0.8.
CST composite is an average of the following scores: confirmed correct verbal, confirmed correct perceptual, percent accuracy sorting, percent accuracy description, and recognition description. Before averaging, scores were converted from scaled scores to standard scores to be consistent with FSIQ.
