MedicalResearch.com Interview with: Lukas D. Lopez Doctoral Candidate Psychological Sciences, Developmental Psychology University of California, Merced MedicalResearch.com: What is the background for this study? What are the main findings? Response: "This study is unique because it uses LENA recording devices which are small recording devices that infants wear in the pocket of a vest that record all infant babbles and caregiver responses in the home. We then had trained listeners annotate infant-adult vocal exchanges within sections of those recordings focusing on the specific types of sounds infants made and specific types of adult responses to those sounds. Using this combination of methods is distinctive because it allowed us to capture a more natural picture of a family's language environment in the home context, whereas most research on this topic is conducted in the laboratory. We then related this information to caregivers' reports of their infant's vocabulary. Our study finds that the caregivers who scaffold and elaborate on their infant’s babbling report that their infants can say more words." (more…)
