Figure 2. Stimulus temperatures (°C) for two-point vs. line stimuli (means±SEM).

Figure 2

Infrared video thermography revealed that stimulus temperatures were not different between 2 points and line patterns at 4cm and 8cm distances. However, at 12cm distances, the temperatures of the two-point stimuli were significantly lower than those of the lines. Accordingly, the 12cm psychophysical data have been excluded from analyses.
