Physical changes in the brain enable children of this development stage to think faster, focus
attention, follow more complex sequences of action and ideas, and inhibit impulses. This growth
allows for five cognitive abilities that Jerome Kagan and Norbert Herschkowitz believe children in the
Western Cultures develop by the end of early childhood (Woolfolk & Perry, 2011).
The first of these five, integrating the present with the past begins around age 4. For example, a
parent may leave, saying they will get the child a surprise, upon return, the child may see a bag and
ask if it is their surprise. The second ability is detecting relationships between events and concepts.
Children learn to use and connect words such as larger, shorter, taller and smaller correctly. They
can also make these connections in certain situations. They may understand that an object may be the
shortest in one group, but not in the other. By the age of seven, an appreciation of causality has
developed. This means that when something new happens, the child can reflect on and understand
why it happened (Woolfolk & Perry, 2011).
Anticipating the future is another newly developed skill. Four year olds typically do not understand
the concept of something being sooner or later, however a seven year old can understand that their
birthday may be next week, but Christmas is not until next year. The last cognitive ability is the
reliance on semantic categories. This includes using words and networks of meanings to represent or
remember a specific event. In the early ages of this developmental stage, children use simple word
associations. For example, if you ask a four or five year old about a cat, they may tell you about their
pet, and name characteristics such as the color. However, six and seven year olds may expand their
response to lions, sounds they make or a cats behavior. The use of meaningful categories allows
children to think more logically and expand their knowledge (Woolfolk & Perry, 2011).
Lev Vygotsky and Jean Piaget are two psychologists that studied the cognitive development of
children. Piaget had 3 basic components to his theory: schemas, processes that enable transitionsfrom one stage to the other, and specific stages of development. He proposed that cognition
develops in stages in all children in the same order. Each child must complete one, before you
moving to the next. Children will progress through each stage at different times, and some may
never reach all of them (Woolfolk & Perry, 2011).
Between two and seven years old, children typically reach the pre-operational stage. Children work
to master the ability to think symbolically about actions, rather than carrying out actions. For
example, words may be used to symbolize feelings. Semiotic function is the ability to work with signs
and symbols. To master this, children first learn to imitate actions or sounds of people that may not be
present. They then learn to use symbolic play, such as using a block of wood to represent a truck.
They move towards using drawing to represent something, and then finally are able to form mental
images (Woolfolk & Perry, 2011).
Conservation is another principle Piaget introduced. This is the idea that the amount of something
stays the same, even if the appearance is changed. Children at this stage struggle with this because
they are unable to decenter, meaning they can only focus on one aspect of a situation at a time. This
in part is due to what Piaget has named egocentrism, the idea that children can only see things from
their perspective. An example is children speaking about something even though no one is listening
(Woolfolk & Perry, 2011).

On the other-hand Vygotsky felt that social interactions played the most significant role in cognitive
development. He viewed language as the most important symbol system. Private speech helps
children move towards self-regulation. He sated that self-regulation occurred in stages. The first
stage is that others use language and gestures to regulate the childs behavior. The child then begins
to use the language to regulate others and themselves through private speech. The regulation of self
through private speech peaks around the age of nine years old. The two theories are compared in
table Piagets theory supports the idea of learning through activity and play. Vygotsky suggests the
importance of assisted learning through support and scaffolding (Woolfolk & Perry, 2011).
Although there are many different processing theories, they all share some of the same basic
principles, and acknowledge that there are different kinds of memory, which include short-
term/working memory and long-term memory. Long-term memory is the storing of information that
we know, while short term/working memory is the information we are currently thinking about and
briefly hold on to. In studying information processing and childrens processing, the most consistent
find is that childrens thinking is domain-specific. This means that specific cognitive abilities or areas
of knowledge, such as visual perception, language, spatial reasoning number, physics, etc, are
studied separately. Children may excel in one domain at a particular age, but not as well in others
(Woolfolk & Perry, 2011).
An understanding of numbers occurs during this developmental stage. Children begin by
learning the words that represent the numbers. They then have to learn how to count. Thereare 3 specific principles offered by Gelman and Gallistal on how children count. The first is
the one-to one principle, where each item is assigned only one name. Stable order principle,
the second, is that numbers have to be said in the same order every time. The last is the
cardinal principle, where the last number is the cardinal value of all the items that were
counted. These are typically grasped on small numbers, under five or six, between the ages
of two and four. By the time children are five, they begin to grasp the abstraction principle,
which addresses what to count. These principles can be mastered with practice. Aside from
knowing how to count, students also need to be able to relate and reason with numbers. One
way to do this in this stage is to incorporate it into their dialogue (Woolfolk & Perry, 2011).

Relationship to Social Speech Negative; least socially and
cognitively mature children use more
egocentric speech.
Positive; private speech develops
out of social interaction with others.

Attention, memory and problem solving are important aspects of information processing. Effort and
attention have to be exerted for mental operations to occur at this age. Eventually mental operationscan become automatic. It is critical that children learn how to regulate their attention by focusing on
information that is relevant. All of this contributes to the ability to plan, control, and monitor their
attention. Any discrepancies in these are thought to be due to attention disorders and the
environment of the child. Discrepancies in attention can directly affect learning acquisition (Woolfolk
& Perry, 2011).
Development of memory is another critical aspect of information processing. It is not until the age of
10 or 11, that children have adult-like memories. When studying memory, there are three basic
components: memory span, memory processing efficiency, and speed of processing. The more
efficient these components are in working together, the greater amounts of information can be held in
the memory. Children struggle with memorizing longer series of information because they have
fewer strategies for memorizing and less knowledge. As they grow older, these strategies andknowledge improve (Woolfolk & Perry, 2011).
By the age of five or six, they begin to discover the strategy of rehearsal. They may also learn to
cluster information. Children under the age of five can be taught these two strategies, but need to be
reminded to use them efficiently. Working memory is also limited, but improves with the use of
improved strategies (Woolfolk & Perry, 2011).
Preschool children remember events that occur even before the age of two or three and can
accurately describe these events but very few of these memories are retained into adulthood. Their
ability to describe events, is based on whether the event was positive or negative and their adult
interactions in telling stories. Because of this, there is a lot of discussing on the reliability of eye-
witness testimonies from children. In the early stages of the developmental level, children may
remember specific actions, but not necessarily who conducted the action. Also, they way the adult
asks the questions will influence the way the child responds. As children get older, they are able to
separate the event from other related events in the telling of the accounts. As they enter pre-school,
they move from citing details of the event, to begin to incorporate feelings in their recounts. They
also begin to use connections and qualifiers, such as then, before, after, etc They may begin to
make connections as to what other people were feeling or doing during the event (Woolfolk & Perry,
2011).
An important role in cognitive development is pretend play. One example is using objects to
represent other objects. It prepares children for abstract thoughts and serves as a basis for high-
order thinking, including hypothetical thinking. Vygotsky suggests that pretend play leads to the
creation of rules and following them, which enables a child to follow rules in real games (Woolfolk &
Perry, 2011).

Childcare Facility Factors Believed to Influence Higher CognitiveOutcomes of Children Attending
1. High ratio of adults to children.2. Adult employees have college degrees in early childhood training.3. Children are given opportunities to talk listen and be listened to.4. Materials, toys, activities and equipment supports learning.5. Opportunities for dramatic play, blocks and art.6. High parental involvement.
Table 3.5 Source: Woolfolk, A., & Perry, (2011). Child and adolescent development. (1 ed., pp.236). Upper Saddle River, NJ: Pearson Education, Inc.
Pretend play also has a role in helping children deal with emotions and practice conflict resolution. In
boys, they tend to be an imaginary characters, while girls tend to have imaginary friends (Woolfolk &Perry, 2011).
There has been a lot of research on early childcare over the past twenty-five years. Deborah Vandell has
found that several factors that affect the cognitive outcomes. The factors listed in Table 3.5 are all critical
components of the childcare facilities that produced higher cognitive outcomes (Woolfolk & Perry, 2011).

Woolfolk states that language is a major cognitive accomplishment of early childhood (Pg. 209,2012). Biological, cultural, and experiential are factors that influence language development. Culture
plays a big part in language development, especially in children that come from diverse
backgrounds such as dual language homes. For a child to become bilingual, they must be exposed to
the languages early in life, use and hear them in a consistent and sustained manner and be exposed to
them among a wide range of contexts (Woolfolk & Perry, 2011).
If they are exposed to them from birth, they should reach the development milestones at about the
same time that other children that are not bilingual do. The key idea is that as children develop their
cognitive abilities, they dually develop language. In order to develop language, they must find
patterns in ways that others use symbols in language and read the intentions of others to interpret
meaning (Woolfolk & Perry, 2012).
Emergent literacy is made up of the skills, knowledge and attitudes that develop along the way as
children learn to read and write, as well as the environments and contexts that support these
developments (Woolfolk, Pg 205). According to research, the two categories of skills needed for
later reading is the ability to understand sounds and codes (phonemic awareness) and oral language
skills that include receptive and expressive language. Conversations with adults and joint reading,
which includes using books to talk about letters, sound, words, and concepts are two important
activities that facilitate in the development of emergent literacy (Woolfolk & Perry, 2011).

In acquisition of language, there are milestones children meet at
specific periods. Major milestones are list in Table 3.6 By the time theyare 5, they should have mastered all the phonemes, or sounds, of their
language. English speaking children usually struggle with specific
clusters of thejand vsound (Woolfolk & Perry, 2011).
By the age of eight years old, children can hold a sentence in memory
and are able to focus on the meaning of it. They move from having an
expressive vocabulary of about 1,000 words at ages three to four years
old, to 1,500 between four to five years old, and finally 2,600 between
five and six years old. By the age of six, children have a receptive
vocabulary of about 20,000 words. They learn these new words
through a process of fast mapping, where they hear a word and locate
its meaning by making a connection to something they already know.Children struggle with abstract words, do not understand subjunctive
cases due to their cognitive abilities, and take everything literally, therefore may not understand
metaphors. As they learn new words, they begin to organize them through sequencing and
hierarchies, chunking into categories , and making connections, associations (Woolfolk & Perry,
2011).
By the age of five years old, children can begin to
understand language and how it works. They only
understand language as a way to communicate and give
meaning. They can begin to look at it not only the meaning,
but the correct way to use it. Children move away from
using words they have heard incorrectly to learning therules of grammar and syntax. However, they may apply the
rules to everything, such as when they learn to use s for
plural, they put it on everything including geeses for
goose. This is called overregulating. This shows the
logical and rational processes children are going through as
they try to make new rules fit in their existing schema.
Children struggle with the order in which words are used in
a sentence. They understand that the dog was hit by the car if you say, The car hit the dog.
However, if you say The dog was hit by the car, they may think the dog hit the car. This is part of
their learning process of syntax. As they reach the later years of this development stage, they can
begin to understand sentences like this, however, they
may not use them in their speech (Woolfolk & Perry,2011).
Children are also beginning to learn how to
appropriately use language in social situations
(pragmatics). Just because children are talking to each
other, that does not mean they are learning and using
pragmatics. It is visible when they begin to use simpler
sentences, make commands and begin to provide
descriptions of a situation (Woolfolk & Perry, 2011).

In younger children, the way they view themselves and then in turn describe themselves, is usually
done using concrete descriptors. Table 3.7 lists the different areas they use to describe themselves,
as well as examples (Woolfolk & Perry, 2011).
Because of their cognitive abilities and the fact that they view themselves in this manner, they cannot
conceptualize that people can possess opposite attributes. For example, they cannot understand that
people can be happy and sad at the same time. They believe that something is always what it is,
whether always nice or always bad. Children are always optimistic about the future, and believe
they can do more than they actually can. They cannot distinguish between what they would like to be
and what they actually are.
Because of this, they do not use
other peers to compare
themselves to, rather they use
their current abilities. By the end
of this development stage,
children begin to recognize the
abilities of their peers, and begin
to measure themselves based on
that. They also start to realize that
their image of themselves can
shift, depending on the situation
and the phase of their life. Because they are beginning to recognize other peers, they begin to ratethemselves based on how their peers perform on specific tasks. They begin to see and understand
their strengths and limitations. The way they describe themselves shifts from very concrete to more
abstract (Woolfolk & Perry, 2011).
Like their self-concept, they generally have high self-esteem. Their self-esteem is influenced by the
people around them. If they receive positive reinforcement when trying new things, they will most
likely continue with high self-esteem. They look for affirmation from their caretakers and people
around them. As children reach the later stages
of this developmental stage, their self-esteem
becomes more altered. It changes because they
may not be receiving as much positive
reinforcement, and because they are beginningto experience success and failure. It is believed
that if children have high self-esteem at age seven
and eight, it will continue with them as they
progress through later stages, unless that person
begins to face unhealthy criticism and stresses
(Woolfolk & Perry, 2011).

Self-Concept, Identity & Motivation
Development
Pre-K to 2nd Grade

A large component of self identity is gender awareness. The can identify with others of the
same gender and imitate the behaviors of those once they identify their own gender. They
may begin to associate specific objects or activities and appropriateness with specific
genders, and in turn express preferences based on those associations. In preschool
classrooms, you may expect to see more boys playing with blocks or vehicles and girls
playing house and dress up. When they play together, boys will generally take on the
masculine roles, while girls will take on the famine roles. In pre-school, the preference for
same-sex playmates usually begins and continues throughout school age. By ages three to
five years old, they have develop gender stability, or the acknowledgment that little girls
grow up to be women and little boys grow up to be men. Gender consistency, gender cannot
be altered by changing looks or behavior, is usually developed by ages five to seven years
old. Gender segregation, which begins to develop in the early stages, increase during the
later stages and lasts throughout adolescents, is due in part to the idea that interests and
styles of individuals are added by recognition of gender. This in turn affects what specific
things may motivate these individual children (Woolfolk & Perry, 2011).

Peer Relations & Moral DevelopmentPre-K to 2nd Grade
+
Self regulation is the ability to control your thoughts and actions voluntarily, for the purpose of achieving
personal goals and responding to environmental factors. It is thought that it begins to develop very
early in life. By the time a child reaches preschool, their ability to control their emotions and behaviors
has significantly increased due to their self-awareness and cognitive abilities. Also, their vocabulary at
this point, allows them to talk about their emotions and reflect upon them. Adults play a vital role in the
acquisition of self-regulation, in how they interact and respond to children, and in how they react to their
own emotions when they are around children. As children progress towards the end of this stage, they
rely less on using their parents and caretakers as a way to monitor and guide their reactions. They can
have better control of their emotions because they can associate consequences to their reactions. How
children regulate themselves, has a direct correlation with the relationships they build with their peers
(Woolfolk & Perry, 2011).
As they enter preschool, children become more aware of relationships with peers. They shift from
seeking attention from adults, to seeking friends to play and share information with. Children become
less egocentristic, and more aware of the needs of others. They become more open to consider how
others feel and try to avoid conflict with their peers. When they do have conflict, they are able to use it
to develop social problem solving skills. At this age, they begin to
label their peers as friends. Their ability to cooperate, compromise,
negotiate and resolve conflicts is magnified by their want to maintain
their friendships. In turn, these friendships provide emotional support,
security, affection and intimacy and assistance for children. Children
that form these friendships early on, seem to cope better when faced
with stressful events. As they get to the end of this stage, they begin to
put view friendship in relationship to social context and concreteactivities (Woolfolk & Perry, 2011).
The shift away from egocentrism opens the door for perspective
taking. This allows children to understand that people may not feel the
same way about something that they do. In turn,this enhances theirability to build friendships, and begin to arouse moral development. There are a lot of theories on moral
development. Lawrence Kohlberg offers six stages of moral development (Woolfolk & Perry, 2011).
Children in preschool, are usually in stage 2, exchange of favors. By the time they enter
Kindergarten and up to second grade, they have entered stage 3, the good boy/good girl stage.
These children begin to focus more on sharing, helping and cooperating with others, which is
motivated by their concerns for others. Another factor that influences their moral development,is their culture and family practices. They begin to internalize those moral principles instilled
through instruction, supervision and correction. When children are explained why specific
things are right or wrong, they can internalize them. In the early stages, children see equal as
fair, but once they reach the age of six or seven years old, they develop a sense that equal is not
always fair. They can begin to understand some people have exceptional needs and may need
to be treated differently in order for something to be equal. Higher levels of moral
development influence engagement in more prosocial behaviors. In turn, this affects their
ability to form friendships (Woolfolk & Perry, 2011).

Physical DevelopmentPre-K to 2nd Grade
Body Growth
Children follow a typical growthcurve, with respect to weight and
height. The charts at the right
represent the typical growth of
girls and boys ages 2 to 20.
Variations in growth curves may
occur if a child is undernourished
or malnourished. They may not
grow as fast or as tall as children
who have assess to a healthy diet or
adequate food (Woolfolk & Perry,
2011).
Rapid growth occurs during infancy
and toddler years (through age 2).
When children reach early childhood,
growth begins to slow, the amount of
fat begins to decrease and muscle mass increases. Typically, girls have more fat, and boys have more muscle mass.
Body mass is affected by other factors as well, including heredity, environmental factors, and ethnicity. According to
Woolfolk (2012, Pg. 170), children of Northern European and American Caucasian descent tend to have larger frames
and be taller than children of Asian descent (Woolfolk & Perry, 2011).
The food pyramid is a guide for an adequate diet for children in this stage of
development. Diet affects tooth, brain, bone and cognitive health and development
Because the growth rate in early childhood is lower, fewer calories are needed andtheir appetite may decrease. Children may become very selective about what they
want to eat but is important to provide a balanced diet. The amount of exercise also
affects body mass and bone development. At these ages, children lose their baby
teeth, and begin to get their permanent teeth. (Woolfolk & Perry, 2011).
Brain Development
Child brains reach 90% of their adult size by age 5. Although the brain continues to
grow, the change process is not as dramatic as that of infancy and earlier years.
Production and pruning of brain synapses is still occurring, however, the production
decreases as pruning increases (Woolfolk & Perry, 2011).
Near the end of this development stage, the brain continues to add cells and
connectors. The process of myelination during the younger stages helps to
increase brain efficiency. Children are able to begin to make sense of
sequences, and tell what should come next. They can think quicker, and hold
on to more thoughts due to increased efficiency of the memory part of the brain
Children are now physically capable of learning simple games and language
(Woolfolk & Perry, 2011).
Most children favor the left hemisphere, which controls our language processing and step-by-step reasoning. The
right side of the brain is responsible for most of the spatial-visual information and appreciation of arts and emotions.
Children are typically not able to begin higher cognitive functions, including planning, goal setting and controlling
inappropriate behavior until age of 9 (Woolfolk & Perry, 2011).

Motor Development
Because their physical development begins to slow and their center of gravity shifts to the center of their body,
children are able to refine their gross motor skills. They have improved balance and better hand-eye coordination.
Although they have perfected walking, and can run, jump and throw by the age of 3, they cannot control these actions
until about the age of 4 or 5. They also begin to have increased flexibility (Woolfolk & Perry, 2011).
Gross and fine motor skills progress from one skill to the next. As children get older, they become more controlled
and coordinated. By age 4 or 5, most have developed the fine motor skills required for tying shoes, buttoning and
zipping articles of clothing. They are also able to use crayons and pencils to draw. Typically, by the age of 4 or 5,these children would have reached the pictorial stage of drawing. This means we can recognize specific object in
their drawing. We may also be able to identify their preference for the use of one hand over another at this stage.
The development of these fine motor skills and improvement in hand-eye coordination is what helps to prepare them
for the ability to write rapidly and automatically when they enter third and fourth grade. Table 3.3 describes a few
gross and fine motor skills milestones for each age level for this developmental period (Woolfolk & Perry, 2011).

As is in body development, factors, such as gender, genetics, environmental factors, physical disabilities and
temperament play a role in the development of these skills. There are marked differences on the abilities and skills
between males and females. Boys are typically stronger, especially in their upper body, and more physically active
than girls. Because of this, boys generally jump higher or throw a ball farther and faster. Girls coordination is
generally more well defined, which helps them do tasks such as balancing on one foot better. They also generally
have increased flexibility, which influences their increased involvement in gymnastics and dance (Woolfolk &
Perry, 2011).
