The effect of experimental exposure condition on norm judgements and underestimation in Study 3
| Normal weight exposure | Obese exposure | Test results | |
|---|---|---|---|
| Female (N = 142) | (N = 68) | (N = 74) | |
| Upper norm boundary | 4.66 (2.28) | 5.28 (1.97) | t(140) = −2.31, p = 0.022, d = 0.37 |
| Lower norm boundary | 2.18 (1.01) | 2.31 (1.38) | t(140) = −0.08, p = 0.935, d = 0.01 |
| Average | 3.60 (1.07) | 4.32 (1.29) | t(140) = −3.36, p = 0.001, d = 0.52 |
| Norm width | 3.47 (2.72) | 3.91 (2.17) | t(140) = −1.92, p = 0.057, d = 0.33 |
| Underestimation of weight status | 9 (13%) | 32 (43%) | χ 2(1, N = 142) = 15.54, p < 0.001, V = 0.33 |
| Male (N = 148) | (N = 75) | (N = 73) | |
| Upper norm boundary | 4.56 (1.50) | 5.52 (1.98) | t(146) = −3.27, p = 0.001, d = 0.50 |
| Lower norm boundary | 2.67 (0.88) | 2.74 (1.01) | t(146) = −0.048, p = 0.962, d = 0.01 |
| Average | 4.18 (1.10) | 4.78 (1.19) | t(146) = −3.20, p = 0.002, d = 0.50 |
| Norm width | 2.88 (1.82) | 3.78 (2.42) | t(146) = −2.12, p = 0.036, d = 0.35 |
| Underestimation of weight status | 62 (83%) | 67 (92%) | χ 2(1, N = 148) = 2.75, p = 0.097, V = 0.14 |
For upper norm boundary, lower norm boundary and average, values refer to body sizes selected using body size guide scales and are M (SD). Norm width refers to number of body sizes selected using body size guide scales are M (SD). Underestimated refers to number of participants underestimating the weight status of the overweight model (frequency [%]).
