Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The detection threshold (°C), defined as the smallest temperature change relative to the base temperature at which a participant reliably reports a temperature sensation (usually corresponding to a detection probability of 50%). | — |
Secondary
| Measure | Time frame |
|---|---|
| The slope of the curve around the threshold value, which indicates how strongly the detection probability increases. A steeper slope indicates a more consistent perception near the threshold. | — |
