The aim was to study emotional responses to thermal stimulation. Stimuli were varied by increasing or decreasing temperature by 2, 4 or 6°C in respect to the participants’ hand temperature. The stimuli were either dynamic (i.e. heated or cooled while touching) or pre-adjusted (i.e. heated or cooled to the target temperature before touching). The results showed, for example, that 6°C change in temperature was rated as unpleasant, arousing, dominant, and avoidable especially when the stimulus was warm. 4°C increase was rated as arousing, dominant, and pleasant. In addition, pre-adjusted 6°C increase elevated the physiological arousal in terms of skin conductance response.
