„’Spending time just talking‘ is the parental activity most frequently and most strongly associated with students’ life satisfaction. And it seems to matter for performance too: students whose parents reported ’spending time just talking‘ were two-thirds of a school-year ahead in science learning, and even after accounting for social background, the advantage remains at one-third of a school year.“
