If we turn the question around and now say not, what does the laughter sound like in terms of being real or posed, but we say, how much does this laughter make you want to laugh, how contagious is this laughter to you, we see a different profile.
Jeśli zadamy pytanie nie o to, jak brzmi śmiech: szczerze, czy nie, ale o to, jak bardzo nas rozśmiesza  i jak bardzo jest zaraźliwy, ujrzymy inny profil.
