Gender differences in human interpersonal conflicts: A reply to Ingram et al. (2012)

From the book : Evolutionary Psychology 11 issue 4 : 781-787.
In the article, I comment on the study results of Ingram et al.
(2012).
Feelings of anger were hypothesized to be reported more often in the descriptions of past conflicts of boys than in the descriptions of past conflicts of girls.
However, the authors found that boys were no more likely than girls to describe feelings of anger ensuing from a conflict.
An explanation of this interesting finding is not provided in the discussion section.
The present study provides possible theoretical explanations for this finding, also using the results of our studies published in the past.
