The fresh new graphs reveal the least-square indicate (± SE) change in elegance between products (trial dos value minus demo step one worth) having confident beliefs proving that rating was high on the 2 nd trial compared to new step one st demo. Pubs with different letters more than them are notably unlike for every most other playing with Tukey remedied numerous 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).

Bars with various emails over are usually significantly different from for each other using Tukey fixed numerous comparisons.
