Question

ray believes that a stimulating first date, such as attending a sporting event or visiting an escape room, helps ensure \chemistry\ with a prospective partner. rays belief best illustrates: the feel - good, do - good phenomenon. the spillover effect. relative deprivation. the adaptation - level principle.

Explanation:

• The feel - good, do - good phenomenon refers to when people do good deeds because they feel good. This is not related to Ray's belief about the first date.
• Relative deprivation is about feeling deprived compared to others. It has no connection to the situation of a first date and "chemistry".
• The adaptation - level principle is about getting used to a certain level of stimulation. This is not relevant to Ray's idea.
• The spillover effect is when physiological arousal from one situation spills over to another. A stimulating first date (physiological arousal from the event) can spill over and be misattributed as "chemistry" (arousal towards the partner).

Answer:

the spillover effect.
