Infant cognitive development

Abstract: The impact of maternal depression and adversity on mother-infant face-to-face interactions at 2 months, and on subsequent infant cognitive development and attachment, was examined in a low-risk sample of primiparous women and their infants. The severe disturbances in mother-infant engagement characteristic of depressed groups in disadvantaged populations were not evident in the context of postpartum mood disorder in the present study. However, compared to well women, depressed mothers were less sensitively attuned to their infants, and were less affirming and more negating of infant experience. Similar difficulties in maternal interactions were also evident in the context of social and personal adversity. Disturbances in early mother-infant interactions were found to be predictive of poorer infant cognitive outcome at 18 months. Infant attachment, by contrast, was not related to the quality of 2-month interactions, but was significantly associated with the occurrence of adversity, as well as postpartum depression.

Abstract: Our encounters with the physical world are filled with miraculous puzzles - wind appears from somewhere, heavy objects (like oil tankers) float on oceans, yet smaller objects go to the bottom of our water-filled buckets. As adults, instead of confronting a whole world, we are reduced to driving from one parking garage to another. "The Child's Conception of Physical Causality", part of the very beginning of the ground-breaking work of the Swiss naturalist Jean Piaget, is filled with creative experimental ideas for probing the most sophisticated ways of thinking in children. The strength of Piaget's research is evident in this collection of empirical data, systematically organized by tasks that illuminate how things work. Piaget's data are remarkably rich. In his new introduction, Jean Valsiner observes that Piaget had no grand theoretical aims, yet the book's simple power cannot be ignored. Piaget's great contribution to developmental psychology was his "clinical method" - a tactic that integrated relevant aspects of naturalistic experiment, interview and observation. Through this systematic inquiry, we gain insight into children's thinking. Reading Piaget will encourage the contemporary reader to think about the unity of psychological phenomena and their theoretical underpinnings. His wealth of creative experimental ideas probes into the most sophisticated ways of thinking in children. Technologies change, yet the creative curiosity of children remains basically unhindered by the consumer society. Piaget's data preserve the reality of the original phenomena. As such, this work will provide a source of information for developmental psychologists and those involved in the field of experimental science.
