CHAPTER 6
Realms of Cognition in Middle Childhood In the preceding chapters, we have described
some of the major developmental tasks and achievements of infancy and the preschool years. The
pace of developmental progress is quite remarkable during those pe
riods, and much of the
foundation for later achievements is laid down. Consider, for example, the qualitative difference
between the skills of a newborn and those of his 6
-
year
-
old sibling. Development has been so rapid
during this first 6 years that it is
not uncommon for parents with a newborn second child to view their
older child as having grown up, almost overnight, because of physical size, motor skills, and verbal
ability. However, in middle childhood, the years spanning the elementary school period,
children are
still far from grown up. Their growth takes on new forms in this stage, metamorphosing into ever
more highly differentiated patterns of cognitive, emotional, and social functioning. For children at the
start of the middle years, school and it
s peer group structure represent a new frontier. The
movement into the school years ushers in a whole new set of developmental challenges for children.
Many youngsters begin to spend longer periods away from home, and all children must adjust to
more rigor
ous schedules. They must learn to control their behavior, monitor their attention, and
acquire more formal and more complicated academic competencies than have been formerly
attained. They must make friends and learn to navigate the schoolyard, with its gr
eater demands for
athletic prowess, social skill, and cooperative negotiation of conflicts. They must also learn the rules
of the group and when to abide by them. They must learn what it means to be male or female, not to
mention what it means to be themse
lves. So many challenges await them. However, children at
elementary school age are also more adept at almost every task when compared to their preschool
-
aged siblings. Observing the eagerness and energy young children exhibit in the early school years
mak
es it easy to understand the capacity for industry that Erikson described (see Chapter 1). For
most children, the challenges of school and peer group will be mastered gradually, and in many
different ways. Armed with foundational skills in language, mobili
ty, understanding of self and others,
and self
-
control, the youngster is now poised to assume membership in a larger social network.
Clearly, the years of elementary school, as the years to follow, are marked by ups and downs. These
normal fluctuations cre
ate opportunities for helpers to provide support or guidance for children, their
families, and their teachers. What are the cognitive, emotional, and social needs of children at this
stage? What approaches are most helpful given children’s developmental le
vel? In the next two
chapters, we will attempt to provide you with information that will be useful when working with
children at this point in their development. Your understanding of cognitive development, the focus of
this chapter, will enable you to und
erstand children’s ways of construing the world, helping you
appreciate their academic needs as well as the intellectual bases for their friendships, gender roles,
moral understanding, and conflicts. BRAIN AND BEHAVIOR Let’s begin by briefly considering th
e
child’s changing brain. Changes in brain size and organization accompany the accomplishments of
middle childhood. It is tempting to assume that these brain changes are “maturational,” that is,
triggered by pre
-
programmed genetic activity. But remember th
e epigenetic process when you think
about brain development: “it is the ongoing interaction of the organism and the environment that
guides biological . . . development. Brains do not develop normally in the absence of genetic
signaling, and they do not de
velop normally in the absence of essential and contingent
environmental input” (emphasis added; Stiles, 2009, pp. 196
–
197). Put more positively, genes and
experience dynamically interact to influence emerging brain organization. There is no simple answer
t
o the question, “Is this brain/behavioral change genetic or determined by experience?” It is both.
Even though the brain is at 95% of its peak size by age 6, it grows measurably in middle childhood
(Lenroot et al., 2007; Sowell, Thompson, & Toga, 2004; see
Blakemore, 2012). One of the important
contributors to this growth is that white matter increases in volume, a process that continues well into
adulthood. As you learned in Chapter 2, white matter is “white” because of the fatty myelin sheaths
that form a
round the axons, insulating them so that electrical impulses travel faster from one neuron
to another. Myelination increases the speed of neural signals dramatically. Also, functional neural
