Lab 6

¨ We associate colors with feelings, emotions, experiences ¤ Examples? ¤ Among other things, we associate the color red with

love, passion, romance

Elliot & Niesta (2008)

¨ One group viewed a picture of a woman in red (or in front of a red background)

¨ A different group viewed a picture of the woman in another color shirt (or in front of a non-red background) ¤ The group that saw the ”red” woman rated her

attractiveness higher than the group that saw the “non- red” woman n Men were unaware of this favoritism towards red n Women did not show a clear preference for women paired

with red

Lab 6

¨ In our experiment… ¤ Every participant in our sample:

n Viewed an image of a woman in red shirt or white shirt n Rated general attractiveness, facial attractiveness, prettiness

n Viewed an image of same woman in red shirt or white shirt (whatever you didn’t see in the first image)

n Rated general attractiveness, facial attractiveness, prettiness

Lab 6

¨ Our study… ¤ Do people find women wearing red more appealing

than women wearing an achromatic color? ¤ IV?

n Shirt color

¤ DV? (3 of them) n General Attractiveness n Facial attractiveness n Prettiness

Lab 6

¨ Our study… ¤ Hypotheses

n Red shirt rated as more attractive than white shirt n Attractiveness

n H1: µ red > µ white n H0: µ red ≤ µ white

Lab 6

¨ Our study… ¤ What kind of experimental design is this?

n Repeated measures design

¤ How many levels of our IV? n 2: red shirt vs. white shirt

¤ How did we counterbalance level of our IV? n Incomplete: all possible orders n Some saw red shirt first; others saw white shirt first

¤ What statistic? n Paired samples t-test or repeated measures ANOVA

Lab 6 Results: Step-by-step

¨ Write down the question you are trying to answer with your analysis

¨ Write down the analysis you are going to do, including the variables you are including.

¨ Write the result of the analysis ¤ INCLUDE MEANS and STANDARD DEVIATIONS for each level,

for each DV n “The red shirt photo was rated as more attractive (M = ____, SD =

_____) than the white shirt photo (M = ____, SD _____).” n “A paired-samples t-test confirmed that this difference was

significant, t(__) = ___, p = ___. n DO THIS FOR ALL THREE DVs!

Lab 6 Discussion

¨ 3 main components ¤ Review findings of our experiment– consistent with

hypothesis? n How results compare to Elliot and Niesta (2008) and other

research on color and attraction (at least one more)? n How did our study differ? WHY NOTABLE DIFFERENCES? n What might explain these findings?

¤ Limitations of our study, future directions ¤ Implications of these studies Remember to use APA style citations throughout
