All rights reserved Figure 7.1 Maturational Timetable for Motor Control This figure shows average ages at which each behavior is performed. There are considerable individual differences in the rate of development, so the time at which each response occurs is variable. Most infants, however, closely follow the sequence of development outlined here. Copyright © 2012 Pearson Education, Inc.

All rights reserved What Are the Developmental Tasks of Childhood? Nature and nurture work together to help children master important developmental tasks in the areas of language, acquisition, cognitive development, and development of social relationships.

All rights reserved Figure 7.2 Growth in Grade School Children’s Vocabulary The number of words in a child’s vocabulary increases rapidly during the grade school years—an even faster rate of increase than during the preschool years. The chart shows total vocabulary, including words that a child can use (production vocabulary) and words that a child can understand (comprehension vocabulary). These data were reported in 1995 by J. M. Anglin of the University of Waterloo, Ontario, Canada. Copyright © 2012 Pearson Education, Inc.

All rights reserved Testing Infants for Object Permanence Figure 7.5 Testing Infants for Object Permanence In this innovative test of object permanence, infants are shown a series of “possible” and “impossible” events. In (a), a short carrot approaches a screen with a window at the top, then moves behind the screen, and finally emerges from the other side of the screen. In (b), a tall carrot does the same thing. The top of the short carrot is not visible through the window as it passes (because it is shorter than the window), but the top of the taller carrot is visible as it passes the window. Because both of these scenarios are logical, they represent the “possible” events. In (c), a tall carrot approaches and passes behind the screen, but this time the carrot top is not visible through the window (as it should be). Three- to 4-month-old infants gaze longer at this “impossible” scenario than they do at the “possible” events, indicating what may be the beginnings of object permanence.

One mountain has a red cross at the top, one has a small house, and the third is snow-capped. On the other side of the figure (across the table from the child) sits a doll. When asked which mountain view the doll has, the preoperational child typically thinks the doll’s view is the same as the child’s own view. Piaget used this task to illustrate egocentrism or the inability to understand that others’ perspectives may differ from our own. Source: Berk, L. E. (2007). Development through the lifespan. 4th ed.

Copyright © 2012 Pearson Education, Inc.

Increases in hormonal levels • Estrogen and testosterone This leads to sensation seeking and risk taking, as well as preoccupation with body image and sex.
