Table 2. One-sample t tests for each type of ambiguous expression of pain (i.e., morphed with happiness, neutral, and fearful expressions) and for each contrast.

Morphing	Contrast (Primes)	Responses	Reaction times
		t (66)	t (65)
Pain- Happiness	Distress - Compassion	−0.15	−1.87
	Distress - Neutral	−0.15	−0.23
	Distress - Negative	−0.50	0.94
Pain- Neutral	Distress - Compassion	−1.96	−1.54
	Distress - Neutral	−1.61	−1.69
	Distress - Negative	−1.21	−2.95***
Pain- Fear	Distress - Compassion	0.94	1.29
	Distress - Neutral	2.03*	−0.07
	Distress - Negative	0.68	1.08

Note. For Responses, positive values correspond to higher sensitivity to detect pain in ambiguous expressions of pain primed with distress words relative to compassion, neutral or negative primes. For Reaction Times, negative values correspond to quicker detection of pain in ambiguous expressions of pain primed with distress words relative to compassion, neutral or negative primes.
