Abstract
Frontal asymmetry (FA), the difference in brain activity between the left versus right frontal areas, is thought to reflect approach versus avoidance motivation. This study (2012–2021) used functional near‐infrared spectroscopy to investigate if infant (Mage = 7.63 months; N = 90; n = 48 male; n = 75 White) FA in the dorsolateral prefrontal cortex relates to psychopathology in later childhood (Mage = 62.05 months). Greater right FA to happy faces was associated with increased internalizing (η2 =.09) and externalizing (η2 =.06) problems at age 5 years. Greater right FA to both happy and fearful faces was associated with an increased likelihood of a lifetime anxiety diagnosis (R2 >.13). FA may be an informative and early‐emerging marker for psychopathology. [ABSTRACT FROM AUTHOR]
