Question

Quizplus · Accepted Answer

Ekman's studies suggest that simulated facial emotional expressions can influence sympathetic activity, as shown through changes in heart rate and skin conductance. However, there is no evidence to suggest that fear and happiness produce similar changes in the autonomic nervous system, and there is no mention of parasympathetic activity in Ekman's research. Option A is incorrect because Ekman's research actually found distinct facial muscle movements associated with different emotions. Option E is incorrect because choice C and D cannot both be correct.
