Table 1.
Mean values and standard deviations of participants’ main characteristics across both the stereotype threat and control samples.
| Variable | Stereotype Threat | Control | t | p | Cohen’s d | ||
|---|---|---|---|---|---|---|---|
| Mean | SD | Mean | SD | ||||
| Male/female ratio | 16/5 | 17/4 | |||||
| Age (in years) | 70.86 | 4.81 | 70.24 | 4.35 | 0.44 | 0.66 | 0.14 |
| Annual mileage (in thousands of km) | 14.48 | 6.36 | 13.67 | 6.28 | 0.42 | 0.68 | 0.13 |
| Mini-Mental State (score out of 30) | 29.00 | 0.78 | 29.19 | 1.29 | 0.58 | 0.57 | 0.18 |
| Driving task involvement (9-point scale) | 8.00 | 1.84 | 7.93 | 1.33 | 0.14 | 0.89 | 0.04 |
| Manipulation check (9-point scale) | 4.67 | 2.58 | 2.74 | 2.15 | 2.84 | 0.01 * | 0.81 |
Note: SD—standard deviation; t—value of Student’s t-test for two independent samples; p—p-value; * p < 0.05. The Mini-Mental State (range 0–30) is a French translation of the original Mini-Mental State [55]. None of the mentioned differences reached significance across groups, except for the manipulation check.
