Abstract

An important goal of developmental science is to understand how the early organization of the brain and behavioral tendencies are interconnected. A foundational step in pursuit of this goal is to identify brain-behavior relations. Much progress has been made identifying such relations during infancy by linking baseline electroencephalography (EEG) activity to infants’ performance in lab-based measures of socio-emotional and cognitive development. Parent-report represents another resource in expanding our understanding to infants’ behavioral tendencies in their natural environment. The current study explored how parent-report of 6- to 12-month-old (N = 53) infants’ attention and regulatory abilities relates to cortical activity. The results confirmed one key hypothesis that lower levels of theta and higher levels of beta and gamma over the frontal region would be related to infants’ attentional abilities. These results are consistent with the extant baseline EEG literature. Cuddliness was robustly related to higher levels of theta and lower levels of beta over the posterior, likely reflecting infants’ tendency to use another person to self-regulate. Our results indicate links between these cortical rhythms and attention and regulatory processes have infant origins. Our results indicate furture research investigating brain-behavior relations using parent-report is warranted.
