While the languages of the world differ in many respects, they share certain commonalties, which can provide insight on our shared cognition. In a new study Prof. Inbal Arnon and Dr. Ori Lavi-Rotbain explore the learnability consequences of one of the striking commonalities between languages.
A new study in Child Development examined whether typically developing (TD) twins of non-TD children demonstrate enhanced empathy and prosociality. Of 778 Hebrew-speaking Israeli families who participated in a twin study, 63 were identified to have a non-TD child with a TD twin, and 404 as having both twins TD. TD twins of non-TD children (27% males) were compared to the rest of the cohort of TD children (46% males) on measures of empathy and prosociality. Participants were 11 years old. TD twins of non-TD children scored significantly higher than TD twins of TD children in a measure of cognitive empathy (d = .43). No differences were found in emotional empathy and prosociality. The specificity of the positive effect on cognitive empathy is discussed.
