Longitudinal, neuroimaging, and genetic designs independently confirmed spanking’s adverse effects

Evidence

Over the next twenty years, the literature grew considerably. The meta-analyses accumulated. Gershoff’s 2002 synthesis brought eighty-eight studies together and documented the pattern across eleven child outcomes with a consistency that individual studies could not achieve. Longitudinal research improved — studies that followed the same children across years, rather than measuring a single point in time, began addressing the directionality questions that had allowed critics to argue the associations ran from difficult children toward more punishment rather than the reverse. The brain imaging evidence emerged from McLean Hospital in Boston — Tomoda, Teicher, and colleagues documenting reduced gray-matter volume in the prefrontal cortex of young adults who had experienced childhood corporal punishment. Behavioral genetics studies controlled for heritable temperament and still found independent effects of physical punishment on child outcomes. — , The Rod and the Child, 6720
