scheme - correct answer organized ways of making sense of experience - change
with age
-The textbook defines schemes as psychological structures and explains that they are initially in the form
of structured physical actions, such as grasping an object. Later, schemes develop that are mental
structures, such as images and concepts.
mental representation - correct answer the cognitive achievement that marks the
transition to preoperational thought; the ability to hold an image in their mind for a period beyond the
immediate experience
-Note that mental representation develops in the last substage of the sensorimotor stage. It is the
cognitive achievement that marks the transition to preoperational thought.
adaptation - correct answer involves building schemas through direct interaction
with the environment. It consists of two complementary activities: assimilation and accommodation;
designed to result in a more effective interaction between the organism and its environment
-• Note that adaptation is designed to result in a more effective interaction between the organism and
its environment. One way we can become more effective is to change our ideas (accommodate to the
environment, p. 227). The other option is to change the environment (assimilation, p. 227). Everything
you do that leads to a better relationship between you and your environment, whether it involves
changing yourself or changing your environment, is adaptive.
assimilation - correct answer when we use our current schemes to interpret the
external world. The infant who repeatedly drops objects is _______ them into the sensorimotor
"dropping scheme."
accommodation - correct answer we create new schemes or adjust old ones after
noticing that our current ways of thinking do not capture the environment completely
, operations - correct answer mental representations of actions that obey logical rules;
young children are not capable of
-Note how the limitations of preoperational thought, including centration and irreversibility, are related
to the lack of operational (logical) schemes.
egocentrism - correct answer failure to distinguish others' symbolic viewpoints from
one's own. Piaget believed that when children first mentally represent the world, they tend to focus on
their own viewpoint can assume that others perceive, think, and feel the same way they do
-Note that egocentrism as defined in cognitive-developmental theories is different than egotism. An
egocentric person is unaware that other people have different viewpoints or feelings. An egotistical
person is aware that other people have different viewpoints or feelings, but thinks they're wrong. This is
important to keep in mind when studying egocentrism in cognitive development. When a child's
thinking is described as egocentric, there is no implication that the child is choosing his or her viewpoint
over the views of others.
conservation - correct answer refers to the idea that certain physical characteristics
of objects remain the same, even when their outward appearance changes
-•Conservation depends on the ability to understand quantity as a higher order concept comprised of
two sub-concepts. Look at the example of conservation of number in Figure 6.9. Notice that length of a
row of pennies depends on two things: the number of pennies and the density of their placement. In the
conservation of liquid example, notice that volume is determined by height and width. The ability to
organize concepts into hierarchies is a major characteristic of operational thought.
centration - correct answer focusing on one aspect of the situation, neglecting other
important features
-If you had a birthday party for a child with friends, balloons, presents, cake, ice cream...the whole
enchilada...and the child was upset because the cake didn't have enough frosting, can you see
centration as one part of this situation?
reversibility - correct answer the ability to go through a series of steps in a problem
and then mentally reverse direction, returning to the starting point
