COGNITIVE DEVELOPMENT DURING MIDDLE CHILDHOOD
During early childhood, children enter Piaget’s preoperational stage, a phase
marked by significant cognitive development. Here, children begin to think symbolically
about the world around them. As they progress through elementary school, their
cognitive abilities expand further, enabling them to represent ideas and events with
greater flexibility and logic. Although their thinking rules may appear rudimentary
compared to adults', they operate subconsciously yet effectively, enhancing their
problem-solving skills and academic performance.
In the concrete operational stage, for instance, children adopt rules like: "If
nothing is added or taken away, then the amount remains the same." This foundational
rule facilitates understanding of basic arithmetic operations, such as adding or
subtracting zero from a number. Moreover, it aids in conducting science experiments
in classrooms, particularly those involving assessments of liquid quantities after
mixing. Piaget termed this stage "concrete operational" because children mentally
manipulate concrete objects and events to comprehend their properties and
relationships.
During this phase, children transition from purely symbolic thinking to more
operational thought processes, where they manipulate concrete objects mentally. This
evolution allows them to engage more deeply in academic tasks requiring systematic
problem-solving, setting a crucial foundation for their educational journey.
Concrete Operational Thought
From ages 7 to 11, children enter what Jean Piaget termed the concrete
operational stage of cognitive development, a pivotal period characterized by the
mastery of logical thinking applied to concrete realities (Crain, 2005). The term
"concrete" refers to things that are tangible, observable, and directly experienced,
contrasting with abstract concepts or hypothetical scenarios that are more challenging
for children at this stage to grasp.
In this stage, children demonstrate an enhanced ability to apply logical
principles to solve problems related to the physical world. They begin to understand
concepts such as cause and effect, size, and distance in more sophisticated ways
than in earlier developmental stages. For instance, a concrete operational child can
discern that dropping a heavy object will cause a louder noise compared to dropping
a light object. This logical reasoning is grounded in their direct experiences with the
tangible environment.
However, while concrete operational children excel in solving problems tied to
their own experiences and applying inductive reasoning—where multiple observed
instances lead to a general conclusion—they often struggle with hypothetical or
abstract problems. Inductive reasoning involves deriving general principles from
specific observations; for example, after encountering several instances of rude
friends, a child might generalize that all friends are rude. As children progress through
this stage, their thinking gradually evolves, setting the stage for the emergence of
deductive reasoning during adolescence. Deductive reasoning involves drawing
specific conclusions from general principles, which represents a more advanced form
of logical thinking. Now, let's delve into three key capacities that characterize the
concrete operational child, illustrating the developmental milestones during this
significant phase of cognitive growth.
Thought becomes multidimensional
During the concrete operational stage, children between ages 7 and 11 undergo
significant cognitive advancements that enable them to think in more sophisticated
and nuanced ways compared to earlier developmental stages. One of the hallmark
achievements of this stage is the ability to move beyond centration, or the tendency to
focus on only one aspect of an object or situation, towards what Piaget termed
"decentration." This newfound ability allows children to consider multiple dimensions
of objects simultaneously. For example, they can now understand that a glass can
vary in both height and width, and they can coordinate these dimensions in their
thinking.
Multidimensionality and Cognitive Flexibility
Multidimensionality in thinking enables concrete operational children to achieve
several cognitive milestones:
1. Multiple Perspectives
Previously, in the preoperational stage, children struggled to understand
that different observers might have different perspectives on the same situation.
For instance, in the classic Three Mountains task, younger children could only
describe what they themselves saw, unable to consider viewpoints from others.
In contrast, concrete operational children can grasp that different perspectives
yield different observations. This ability is crucial for understanding others'
viewpoints, resolving conflicts, and engaging in collaborative play with peers.
2. Part-Whole Relationships:
In preoperational thought, children often struggled with understanding
relationships between parts and wholes. For example, they might have counted
daisies separately from roses in a bouquet, failing to comprehend that both
together constitute "flowers." However, as they progress through middle
childhood, they develop the capacity to recognize how parts contribute to a
whole. They can logically conclude that a bouquet containing daisies and roses
is composed of more flowers overall, demonstrating a more sophisticated
understanding of part-whole relationships.
3. Classification: As children's experiences and vocabulary expand, so does their
ability to categorize and classify objects. They begin to build mental schemas
that allow them to organize objects based on various criteria, such as shape,
color, function, and size. They also develop an understanding of hierarchical
classifications, organizing objects into broader categories and further
subdividing them into subclasses. This skill becomes fundamental not only in
academic learning but also in everyday problem-solving and social interactions.
Operational Thought and Cognitive Processes
Piaget described the transition to operational thought as a pivotal
developmental shift where thought becomes more systematic and reversible. Key
aspects include:
1. Reversibility: Operational thought involves the ability to mentally undo actions and
understand reversibility. Children realize that certain changes can be reversed to
restore an object to its original state. For example, they understand that water can be
frozen and then thawed back into liquid form, illustrating the concept of reversibility.
This mental flexibility also applies to mathematical operations, where addition and
subtraction can be reversed to yield the original quantities.
2. Conservation: Another critical concept in operational thought is conservation, which
refers to the understanding that certain properties of objects remain constant despite
changes in their appearance. For instance, a concrete operational child comprehends
that the amount of water remains unchanged whether it is poured into a tall, narrow
glass or a short, wide bowl, as long as the volume remains the same. This ability to
conserve quantity, mass, volume, and other attributes is foundational for
understanding scientific principles and mathematical concepts.
In conclusion, the concrete operational stage represents a significant leap in
cognitive development, characterized by the ability to think more flexibly, logically, and
systematically about the world. Children at this stage acquire essential skills such as
multidimensional thinking, understanding of perspectives, mastery of part-whole
relationships, classification abilities, and operational thought processes like
reversibility and conservation. These advancements not only enhance academic
performance but also lay the groundwork for more complex reasoning and problem-
solving abilities in later stages of development.
Thought becomes logical
A third major accomplishment of concrete operational development is that thought
becomes logical, and children can reason logically about concrete events.
• Inferring higher-order characteristics. Where young children’s reasoning was
focused on perceptual cues, older children can now consider a variety of
specific cues and from, use the power of inference, to reach a logical conclusion
about higher-order characteristics. This capacity is seen in children’s
understanding of their own and other people’s capacities and personalities. For
example, after a child does well on multiple multiple assignments in math, she
may conclude that she is high in math ability.
• Identify defining features. Whereas young children’s understanding was
dominated by the most perceptually salient features of objects, with concrete
operational thought, children in middle childhood focus instead on the defining
features of particular objects or states. They are not distracted by the most
salient features; they recognize the underlying defining features. For example,
young children might think that bicycles and toasters are alive (a kind of thought
called “animism,” remember?) because they move. By middle childhood,
however, children understand that even though many mechanical devices (e.g.,
cars, fireworks) and natural objects move (e.g., the sun, the tides), only plants
and animals have a life force, which is the defining feature of being alive.
• Seriation. Arranging items along a quantitative dimension, such as length or
weight, in a methodical way is now demonstrated by the concrete operational
child. For example, they can methodically arrange a series of different- sized
sticks in order by length. This is a complicated task that requites
multidimensional thinking, because each object must be placed so that it is
bigger than the one before it, but smaller than the one after it. These capacities
allow children to make social comparisons as well, estimating who is bigger or
better along some attribute or capacity (e.g., spelling ability, soccer skills,
drawing). Social comparison plays a role in the shift in children’s estimates of
their capacities; they change from the rosy overestimates of early childhood
(where everyone sees themselves as “good” at everything regardless of
performance) to a more accurate view that corresponds to external referents
(e.g., school grades) during middle childhood.
• Transitive inference. Being able to understand how objects are related to one
another is referred to as transitivity, or transitive inference. This means that if
one understands that a dog is a mammal, and that a poodle is a dog, then a
poodle must be a mammal.
Limitations of concrete operational thought. These new cognitive skills increase
the child’s understanding of the physical world, however according to Piaget, they still
cannot think in abstract ways. Additionally, they do not think in systematic scientific
ways. For example, when asked which variables influence the period that a pendulum
takes to complete its arc and given weights they can attach to strings in order to do
experiments, most children younger than 12 perform biased experiments from which
no conclusions can be drawn (Inhelder & Piaget, 1958).
