Now, we don't know, in this context, if we're seeing this because those boys have always had a problem learning to laugh because of these conduct disorders and these callous-unemotional traits that they have, has that affected how they engage with laughter, or have they never had the opportunity to learn to laugh?
Não sabemos, nesse contexto, se esses meninos tiveram dificuldade em aprender a rir por causa desses distúrbios de conduta e se a falta de sensibilidade emocional afetou a maneira com que lidam com o riso, ou se nunca tiveram a oportunidade de aprender a dar risada.
