2. Hypothesis: Monozygotic female twin partners will end up receiving and earning a higher rating of attractiveness than the monozygotic male twin partners would do in the experiment that was conducted in this article.
3. Method: The hypothesis was tested through an experiment where they had photographs of 16 monozygotic male twin pairs and 18 monozygotic female twin pairs. However, they included 30 black and white photographs (8 female pairs and 7 male pairs) and 38 color photographs (10 female pairs and 9 male pairs) as their final …show more content…
The 2nd set of raters were also used to be in charge of recording and rating which twin was more attractive than the other and to rate each twin by how attractive they looked.
Procedure: The 1st set of rater were given a booklet with the LL and RR images of each twin and were instructed to record which pair of mirror-image composites (Twin 1 LL and RR or Twin 2 LL and RR) was more similar and to rate from a scale of 1-7 the similarity of each LL and RR twin pair, 1 being the least similarity and 7 being the most similarity. The 2nd set of raters were given the photographs of the 68 monozygotic twin pairs of both male and female to survey on. They rated which twin of each pair was the more attractive and to rate on a scale from 1 to 7 the attractiveness of each individual.
