Researchers approached potential male and female participants at a number of bars. The researchers repeated this process at 9pm, 10:30pm and 12am. When a potential participant agreed to participate, they were asked to rate a set of pictures (of members of the opposite sex) on physical attractiveness (using a scale of 1-7). The researchers conduct their research and conclude that:Males rate females as more attractive than females rate males; and as the evening progresses both genders increase their ratings of the attractiveness of the photos.

Question

Researchers approached potential male and female participants at a number of bars. The researchers repeated this process at 9pm, 10:30pm and 12am. When a potential participant agreed to participate, they were asked to rate a set of pictures (of members of the opposite sex) on physical attractiveness (using a scale of 1-7).
The researchers conduct their research and conclude that:
Males rate females as more attractive than females rate males; and as the evening progresses both genders increase their ratings of the attractiveness of the photos. However, males increase their ratings over time at a much higher rate than females.
What is being described?

		two main effects and an interaction
		a main effect of gender; no main effect of time; and no interaction
		no main effect of gender; a main effect of time and no interaction
		no main effect of gender; a main effect of time and an interaction of gender and time on ratings of physical attractiveness
