Quizplus · Accepted Answer

Heart rate and breathing rate are two physical indicators that can provide insight into an individual's emotional state. When someone feels a strong emotion, like anger or fear, their heart rate and breathing rate increase. Therefore, measuring these physiological responses can be a good way to infer the intensity of someone's current emotion.

Choice B is incorrect because the velocity of conduction of action potentials refers to the speed at which nerve impulses travel through neurons, which is not directly related to emotional intensity.

Choice C is a possible option, as facial microexpressions can be an indicator of emotion. However, it may not always be reliable, as individuals can hide or control their expressions to some extent.

Choice D is also a possible option, as hand gestures can be used to convey emotion. However, like facial expressions, they may not always be reliable or indicative of an individual's true emotional state.
