Item Adversity in Infancy and Childhood Cognitive Development: Evidence From Four Developing Countries(Frontiers, 2022-12-12) Manalew, W. Samuel; Tennekoon, Vidhura S.; Lee, Jusung; O'Connell, Bethesda; Quinn, Megan; Economics, School of Liberal ArtsObjectives: We investigated whether adverse experiences at age 1 (AE-1) affect the level of and change in cognition during childhood using harmonized data from four developing countries. Methods: Data included children born in 2001/2002 and were followed longitudinally in 2006/2007 and in 2009/2010 by Young Lives study in Ethiopia, India, Peru, and Vietnam. Childhood cognition was measured using the Peabody Picture Vocabulary Test (PPVT) at ages 5 (PPVT-5) and 8 (PPVT-8). We also examined the effect on a change in cognition between age 5–8 (PPVT-Change). The AE-1 scores were constructed using survey responses at age 1. The ordinary least squares regression was used for estimation. Results: We found that children with higher adversities as infants had lower cognition scores at ages 5 and 8. The change in cognition between the two ages was also generally smaller for those with severe adversities at infancy. The negative association between adversities and childhood cognition was strongest for India. Conclusion: The results provide policy relevant information for mitigation of undesirable consequences of early life adversities through timely interventions.Item A Clinical Tool for Assessing Infants' Auditory Acuity(Office of the Vice Chancellor for Research, 2010-04-09) Houston, DerekMy translational research involves developing tools to assess speech perception and language skills during infancy. Language assessment during infancy helps identify children who are at risk for language disorders so that they can receive appropriate intervention as soon as possible. It also allows speech-language pathologists and other clinicians evaluate the success of their therapy and intervention strategies.
