Notes were ranked having attractiveness (for the a great nine-section Likert size) and in which the altruism credit was revealed in a single trial, the latest basic are revealed in the other. The latest graphs let you know the least-square mean (± SE) change in attractiveness ranging from trials (demonstration dos worthy of without demo 1 well worth) which have positive opinions demonstrating the get was highest from the 2 nd demo compared to the step 1 st demonstration. Bars with assorted characters a lot more than them are significantly different from for every other using Tukey fixed multiple contrasting.
We found a significant interaction between trial 2 condition and relationship length (? 2 1 = , p 3 ). However, in contrast to the male participant data, altruistic traits resulted in significantly higher attractiveness ratings, relative to neutral traits, for both long and short-term relationships (Figure 3 ), thought the effect was smaller for short-term relative to long-term relationships. We detected no significant interaction between trial 2 condition and z-skew (? 2 1 = 1.17, p =0.279), suggesting that the strength of altruistic trait did not predict the attractiveness scores given by women participants. In order to verify that differences in response to altruistic traits between the sexes could not be explained by the overall higher average age of female participants, as compared to male participants, we performed an additional analysis on a subset of the data that excluded participants over 23 years old. This revealed a similar pattern to the full dataset (Additional file 4: Figure S1), with a significant interaction between trial 2 condition and relationship length (? 2 1 = , p 2 1 = 0.293, p =0.588).

The newest graphs show at least-rectangular imply (± SE) change in elegance between trials (demonstration 2 well worth minus trial step 1 really worth) that have confident philosophy showing your get are higher from the dos nd demonstration compared to the brand new 1 st demonstration. Bars with various characters over them are somewhat not the same as per other having fun with Tukey corrected several reviews.
