Stability of Individual Differences in Social and Nonsocial Visual Attention From Newborn to 14 Months
Given the foundational nature of infant visual attention and potential cascading effects on later development, studies of individual variability in developmental trajectories in a normative sample are needed. We longitudinally tested newborns (N = 77) at 1–2 and 3–4 weeks, then again at 2, 4, 6, 8 and 14 months of age, assessing individual differences in their attention. Newborns viewed live stimuli (facial gesturing, rotating disk), one at a time, for 3 min each. Older infants viewed a 10-s side-by-side social–nonsocial video (people talking, rotating disk). We found short-term developmental stability of interindividual differences in infants’ overall, social, and nonsocial attention, within the newborn period (1–4 weeks), and within the later infancy period (2–14 months). Additionally, we found that overall attention, but not social and nonsocial attention, was developmentally stable long term (newborn through 14 months). This novel finding that newborn overall attention predicts later overall attention through the first year suggests a robust individual difference. This study is a first step toward developing individual difference measures of social and nonsocial attention. Future studies need to understand why newborns vary in their attention and to identify the potential impact of this variability on later social and cognitive development.
期刊介绍:
Developmental Psychobiology is a peer-reviewed journal that publishes original research papers from the disciplines of psychology, biology, neuroscience, and medicine that contribute to an understanding of behavior development. Research that focuses on development in the embryo/fetus, neonate, juvenile, or adult animal and multidisciplinary research that relates behavioral development to anatomy, physiology, biochemistry, genetics, or evolution is appropriate. The journal represents a broad phylogenetic perspective on behavior development by publishing studies of invertebrates, fish, birds, humans, and other animals. The journal publishes experimental and descriptive studies whether carried out in the laboratory or field.
The journal also publishes review articles and theoretical papers that make important conceptual contributions. Special dedicated issues of Developmental Psychobiology , consisting of invited papers on a topic of general interest, may be arranged with the Editor-in-Chief.
Developmental Psychobiology also publishes Letters to the Editor, which discuss issues of general interest or material published in the journal. Letters discussing published material may correct errors, provide clarification, or offer a different point of view. Authors should consult the editors on the preparation of these contributions.
