“…This investigation sought to determine whether a sample of 15 month old infants, who had experienced maltreatment during the first year of life, would manifest aberrations in neural processing of facial expressions of emotion. We have continued to focus our work on the early years of life because it is a period when critical aspects of neurodevelopment, driven in large part by experience in and transactions with the environment, are occurring (Cicchetti & Curtis, 2006; Huttenlocher, 2002; Stiles, 2008). Moreover, increasingly complex abilities to recognize and understand facial expressions of emotion continue to emerge throughout infancy and early childhood (e.g., Mondlach, Geldart, Maurer, & Le Grand, 2003), and brain areas relevant for facial emotion processing, such as the prefrontal cortex and amygdala, continue to develop through childhood and adolescence (e.g., Giedd et al, 1996).…”
