SOCIAL AND EMOTIONAL DEVELOPMENT

Human beings are social creatures. Connecting to the social world is all the more crucial for the infant, because without the attention and care of others, she would not survive. Fortunately, others (particularly parents) tend to be strongly motivated to involve children in the social world, and to attend to their needs. Just as importantly, the infant is well equipped to participate in the social world from the beginnings of life. Perceptual abilities are closely implicated in the infant’s early social experiences. For example, we noted earlier that infants reveal a very early interest in the human face. This is an interesting perceptual preference, but it is still more important as a social characteristic. After all, faces are one of the best means of differentiating between people, and a valuable source of information about how others are reacting to us or the environment. There is evidence that infants can gather information about faces remarkably swiftly. Researchers using visual preference techniques or measurements of sucking rates have shown that newborns only days or even hours old prefer their mother’s face to that of a female stranger (Bushnell, Sai & Mullin, 1989; Walton, Bower & Bower, 1992). The other senses are exploited similarly. For example, infants as young as one or two weeks of age can discriminate the smell of their own mother’s breasts from those of other breastfeeding women (Porter et al., 1992).
