Jennifer Mascaro finds that a toddler’s gender influences the brain responses and behavior of fathers

Jennifer Mascaro (PhD, Emory Anthropology) published a study in the journal Behavioral Neuroscience based on work she did as a postdoctoral fellow with Professor James Rilling.

The study found differences in behavior fathers showed their children, depending on the child’s gender, from response time to commonly used terminology. The split between fathers of sons and fathers of daughters was also present during brain scans employed in the study. Faced with different pictures, fathers of daughters reacted strongly to pictures of their daughters with happy expressions, while fathers of sons’ strongest reactions were to pictures of their child showing a neutral expression. (eScienceCommons)
