Collectivism and IndividualismEssay Questions:Review the articles, "Cognitive
Development," "Social Development," and "Stages of Moral Development." Consider the
degree to which Erikson’ s, Piaget’ s, and Kohlberg’ s theories apply across cultures. Select
one of the three theories and write an explanation of the degree to which the theory you
selected is applicable to rites of passage across cultures.Consider the degree to which this
theory is applicable to rites of passage across culturesBe specific and illustrate your
explanation with examples.Then describe one change you might make to the theory and
explain how this change might make the theory more applicable to rites of passage across
cultures.Rite of Passage and Developmental TheoriesA rite of passage acknowledges a
significant change in someone’ s life. It represents the transition from one point in
development, such as childhood, to another, such as adulthood. The rite of passage is often
celebrated by some type of ceremony that requires the individual to demonstrate the ability
to successfully advance to the next stage in life.Many rites of passage take place during the
time that Westerners label "adolescence." Some cultures move quickly from childhood to
adulthood and do not identify a period in between such as the teen years.A number of
psychological theorists have attempted to understand development in adolescence and
throughout the life span. Erik Erikson suggested that there are eight stages and that each is
identified by a conflict. If the conflict is resolved, the individual progresses successfully to
the next stage. For example, adolescence is characterized by ego identity vs. role confusion.
At this stage of life, teenagers grapple with who they are. Jean Piaget focused on children’ s
thought processes, and his work did not address the entire life span. Piaget’ s final stage is
the development of abstract thought in adolescence. This stage is called "formal
operations." Lawrence Kohlberg’ s theory focuses on moral development and proposes six
stages. Moral choices are closely tied to cultural norms. There is some controversy
regarding whether or not these theories are appropriate for all cultures. Article:Cognitive

falling meteors, with a flash and an explosion and perhaps somebody’ s castle like roof
perforated.? This quotation by Henry David Thoreau aptly captures the burst of insight that
occurs when an infant discovers the link between their internal and external worlds; when
a preschool child suddenly masters the notion of symbols; when the school-aged child and
adolescent approach problem solving with logic and flexibility; and when the adult
supplants reasoning with wisdom. In essence, the quote captures the gist of cognitive

period (1115 years)For definitional purposes, cognitive development is the process of
reasoning, thinking, and problem solving, which changes over the course of the life span.The
first section of this entry begins with a discussion of infant cognition, the second section
continues with a focus on preschool cognitive development, the third section covers
cognitive development in middle childhood and adolescence, the fourth section discusses
adult thinking, and the entry concludes with the fifth section on contemporary issues in
cognitive development and directions for the cognitive development in the 21st century.The
theoretical perspective responsible for shaping much of 20th-century discourse, thinking,
and scholarship on cognitive development is that of the late Swiss scholar Jean Piaget. As a
genetic epistemologist, he was keenly interested in understanding the origins of knowledge.
He posited such questions as how does knowledge evolve? And where does knowledge
come from? He viewed the acquisition of cognitive development as an active process, where
the infant, child, and adolescent organize their experiences with their environment, adapt to
their environment, and try to maintain a sense of balance with old and new knowledge. He
believed that cognitive development occurred in discrete albeit connected stages
encompassing the first 15 years of life. These stages were universal, invariant, and
qualitatively different.Piaget’ s theory serves as the framework for much of the discussion
on cognitive development in this entry. Table 1 provides an overview of his stages of
cognitive development.Cognitive Development during InfancyHow do infants come to know
their worlds? What rudimentary capabilities are present in infancy? Without the
contribution of Jean Piaget, our knowledge of infant cognition would be limited to the
behaviorist perspective, which asserts that learning or cognitive development occurs in a
stimulus-response mode.How then does cognitive development progress in infancy?
According to the Piagetian perspective, infants ?come to know? their world primarily
through their senses and motor abilities. These rudimentary motor and sensory abilities lay
the foundation for the more complex cognitive skills that will emerge during the latter half
of the sensorimotor period and lay the foundation for the cognitive skills that will emerge
during the subsequent stages of cognitive development.This progression of infant cognitive
development occurs through six substages of the child’ s first stage of cognitive
development, referred to as the Sensorimotor Period. Table 2 provides an outline of the
substages.In substage 1 of the sensorimotor period, infants learn about their world through
the use of their reflexes. Hence, the infant engages in the world, through sucking, reaching,
and grasping. Eventually the use of these reflexes becomes more deliberate and purposeful
as the infant progresses to substage 2 of the sensorimotor period. During these 3 months,
the infant begins to actively involve his or her own body in some form of repeated activity.
Thus the behavior is circular and primary because it centers on the infant’ s own body. It is
not until substage 3, secondary circular reactions, that the infant begins to engage with
objects in the environment. Initially, the contact with external objects (e.g., a crib mobile) is
accidental, then with some planning and purpose subsequent contacts are deliberate. These
contacts with the external objects become a repeated activity.In due course, the infant will

3. be able to combine these basic reflexes and use planning and coordination to achieve a
particular goal, which is substage 4. For example, an infant sees a red ball under a chair in
the living room. The infant crawls, reaches, and grasps the ball, thus coordinating both
internal and external activities to achieve a planned goal.In substage 5, the infant, now
considered the ?little scientist? begins an active exploration of its world, with a trial-and-
error approach. Combining more mature motor behavior with increased planning and
reasoning capabilities, the external world becomes the infant’ s laboratory.Table 2

Secondary circular reactions (4?8 months)Substage 4. Coordination of secondary circular
reactions (8?12 months)Substage 5. Tertiary circular reactions (12?18 months)Substage 6.
Beginning of representational thought (18?24 months)The sensorimotor period culminates
with substage 6 and the emergence of symbolic or representational thought. The toddler
now has a basic understanding that objects can be used as symbols for other objects (e.g., a
pillow can be used to represent a doll in play).A critical attainment during the sensorimotor
period is object permanence. Object permanence is the understanding that objects in our
environment have a continued existence even though they may no longer be perceptually
available. Piaget felt that infants did not fully master this ability until the substage 5 of the
sensorimotor period.There are other cognitive capabilities that begin to emerge during the
first 2 years of life. Language is perhaps one of the greatest cognitive achievements.Table 3
provides a brief summary of language acquisition during the first 4 years of life.Cognitive
Development during the Preschool YearsThe preschool child has now entered Piaget’ s
second stage of cognitive development, the preoperational period. This period heralds a
new perception and understanding of the world, brought on by the attainments of the
sensorimotor period.One major attainment, the ability to engage in symbolic thought,
allows the preschooler to participate in a variety of activities. These activities include
understanding pictorial representations, engaging in pretend play, and mastering basic
numeracy principles.Understanding pictorial representations (i.e., knowledge that pictures
are symbols of real objects) not only reflects the preschooler’ s evolving cognitive skills, but
also permits the preschooler to engage in varying levels of sophisticated social interaction.
As an example, a child is looking through the family photo album with a parent and turns to
a page with a picture of a grandparent; the child labels the person in the picture as grandpa.
Thus, the preschool child has established that he is aware that the photograph represents a
real person. Given their increasing vocabulary, and their developing pictorial
representational ability, preschool children are now able to engage in a variety of learning
interactions and activities with their parents.When children engage in the various forms of
pretend play, they are demonstrating their understanding of the multiple, flexible, and
complex uses of symbols. For example, a child uses a block to represent a telephone, the
child then speaks into the block and carries on a conversation (with another person); the
child then hands the block to a playmate and persuades the playmate to engage in
conversation with the block. Furthermore, there are elements of creativity present, as well
as some rudimentary understanding of the social aspects of pretend play.Even with the
impressive achievement of symbolic thought, Piaget believed that preoperational children

4. experienced some challenges in their thinking and reasoning capabilities, especially
regarding issues of quantity. To assess this, Piaget administered his classic conservation of
numbers task to the preschool children. The task involved presenting the children with two
rows of pennies; one row was then spread out, and the children were asked if the rows
contained the same number of pennies. The preschool children frequently stated that the
longer row contained more pennies. Thus, Piaget concluded that the preschool children
were unable to conserve quantity, and that their performance was due to their inability to
focus on relevant aspects of the task (concentration), their inability to mentally reverse the
operation (irreversibility), and their inability to understand the difference between
transformations and static states. Piaget stated that in order for the preschool children to
conserve numbers, they must understand that the two rows are still numerically equivalent
despite the differences in the appearance of the rows.Research by Rochelle Gelman has
indicated that preschool children comprehend a great deal about numbers. She observed
that preschool children possess two basic concepts about numeracy: number abstraction
principles and numerical reasoning abilities. Number abstraction principles include an
awareness of rules for counting, knowledge of number labels, and strategies for counting.
Numerical reasoning abilities involve rudimentary knowledge of the rules for adding and
subtracting quantity.Table 3 Milestones in Language Development Milestones in Language

months Has a vocabulary of 1,000 words; language is well establishedMemory and language
skills and abilities show vast improvement during the preschool period. For example,
preschool children have well-developed memories for everyday events that happen in their
lives and can articulate those experiences (e.g., what happens when you go to
McDonald’ s?). Language becomes less egocentric, and they are able to engage in various
forms of social discourse. Vocabulary development continues, and individual differences in
vocabulary and overall language competence emerge during this time period.Cognitive
Development during Middle Childhood and AdolescenceThe child in middle childhood has
now entered Piaget’ s third stage of cognitive development, the concrete operations period.
Unlike the preschool child, the concrete operations child has now acquired what Piaget
referred to as mental operations. Mental operations are the ability to use logic when solving
problems. This is evident in such Piagetian tasks as the conservation tasks. Thus, the major
hallmark of this period is the ability to conserve not only quantity but other domains as well
(e.g., liquid, mass).The classic conservation tasks described in the previous section
discussed the challenges that preschool children encounter with such an activity. Children
in middle childhood possess the ability to decenter, to comprehend transformations, and to
engage in reversibility of thought.In addition to these attainments, children in middle
childhood are also able to engage in a variety of classification and categorization activities.
That is, they can appreciate that objects and items belong to several categories. For
example, preschool children and children in middle childhood are presented with the
following classification problem. They are presented with a group of animals consisting of

5. two collies, three great danes, five poodles, and six German shepherds. The children are
asked the question, ?Are there more German shepherds than dogs?? Preschool children
would state there are more German shepherds. On the other hand, children in the concrete
operations period would state that there are more dogs than German shepherds, because
they are able to understand that shepherds belong to both a general category (dogs) and a
subcategory (specific type of dog). This attainment as well as the others discussed below
might well account for the interest that many school-aged children have in collecting objects
(e.g., bugs) and classifying their classmates (e.g., ranking by looks, niceness).Concrete
operations children are also able to engage in the seriation of objects, which involves
sequencing or ordering items according to such dimensions as height, color, size, or
shape.Language and memory abilities also improve during this time period. Vocabulary
continues to build, and memory becomes a vehicle for learning. Their metacognitive skills,
or their understanding of their memory and learning competencies, improve. Consequently,
they are able to use their metacognitive knowledge to improve their learning of academic
material.The adolescent has entered Piaget’ s final stage of cognitive development, the
formal operations period. The hallmark of this period is the ability to think abstractly. In
contrast to the concrete operations child, the formal operations adolescent is able to use
logic to solve problems, and these problems can be abstract rather than concrete in
nature.Also in contrast to the child in the concrete operations period, the formal operations
adolescent can reason about such issues as spirituality, politics, and abortion. In addition to
the ability to think abstractly, the formal operations adolescent can engage in what Piaget
referred to as hypothetico-deductive reasoning. Hypothetico-deductive reasoning is the
ability to generate hypotheses and systematically test each hypothesis. As an example, a
formal operations adolescent wishes to obtain the family car, (e.g., I want to use the car
tonight); he generates several hypotheses (e.g., I could ask mom, or I could ask dad); then he
can mentally test the hypothesis (e.g., Now if I ask mom she might say no, so dad may be the
more reasonable one to ask).Formal operations adolescents can also envision and speculate
about the future, and they can reflect on their own thinking. Thus, programs that encourage
discussion of future plans and goals and decision making are often effective in facilitating
the cognitive development of adolescents.Language and memory skills show a dramatic
improvement over the language and memory skills observed during the middle childhood
period.Cognitive Development during AdulthoodThe formal operations period concludes
Piaget’ s focus on cognitive development. While he acknowledged that cognitive growth
and development continue throughout the life span, he felt that adult experiences were too
diverse to capture characteristics that would encompass the universality of the experiences
of all adults. Nevertheless, his conceptualization of cognitive development has influenced
many theoretical perspectives on cognitive development in adulthood.There is consensus
from investigators who study cognitive development in adulthood that adults conceptualize
problems differently from adolescents and shift from relying solely on logic to combining
logic and ?common sense? when reasoning about issues. Furthermore, there is
acknowledgement by these researchers that the issues that adults are confronted with
differ significantly from the more scientific and academic issues that adolescents have to
deal with.However, there is a great deal of variation in how researchers define adult

6. cognitive development and a great deal of variation in the way in which they frame research
questions about adult cognitive development. As a result, the focus on cognitive
development in adulthood is multifaceted.There are researchers who have put forth the
idea that the Piagetian stages of cognitive development should be expanded to encompass
adulthood. They have introduced the term post?formal reasoning. These scholars maintain
that both the issues and patterns of reasoning in adulthood are qualitatively different from
those of adolescence.Post?formal reasoning could be classified into the following
categories.? 1. Relativistic: These adults reason with the acknowledgement that the ?truth?
is relative and that the implication of a situation is related to contextual issues.? 2.
Dialectical: These adults reason with the acknowledgement that the world is a dynamic and
changing entity and that the interpretation of a situation should be considered in light of an
unstable world.? 3. Problem Finding: These adults reason with the goal of finding solutions
to life’ s problems. There are many variants on the characteristics of post?formal reasoning,
but this conceptualization captures the common assumptions among those who investigate
post?formal reasoning in adults.In contrast, there are researchers who have operationalized
cognitive development as intelligence and investigated which aspects of intelligence remain
the same from young adulthood to late adulthood and which aspects change over the life
span.The Cattell-Horn theory of crystallized and fluid abilities is a frequently cited example
in the literature on aging and intellectual changes. According to these researchers,
intellectual abilities can be classified into two general categories: crystallized and fluid
abilities. Crystallized abilities are those abilities that are assessed by vocabulary and
creativity subtests of IQ measures, and fluid abilities are those abilities that are assessed by
timed reasoning, problem-solving, and math subtests of IQ measures. According to the
theory, crystallized abilities increase or remain the same from young adulthood to late
adulthood, whereas fluid abilities have been shown to decrease from young adulthood to
late adulthood. Recently there has been some debate about whether fluid abilities do in fact
decrease. A study conducted in the 1980s found that older adults could be trained to
improve their performance on measures of fluid ability. Other research has demonstrated
that noncognitive factors may contribute to the observed decline in fluid abilities rather
than age per se.Finally, there are researchers who have examined memory and explored
how memory changes from young adulthood to late adulthood. Three aspects of memory
have been explored by researchers in the psychological literature. These include episodic
memory, which is a person’ s memory for personal events (e.g., what was your 5th birthday
party like?); semantic memory, a person’ s memory for world information (e.g., what is the
capital of France, meanings of words); and cognitive resources (e.g., short-term memory)
and noncognitive factors (e.g., health).Based on findings from the literature, age
comparisons suggest that younger people for the most part have better episodic memories
than do older adults. On the other hand, there are few age differences in semantic memory,
with the exception that younger adults are faster in retrieving semantic information than
are older people. There is some evidence to suggest that working memory declines in late
adulthood. That is, older adults experience some challenges in retrieving information from
working memory. Lastly, such noncognitive factors as health (older people in poor health
experience problems with memory) influence the memory performance of older adults.The

7. general agreement is that there is a great deal of individual variation in adulthood cognitive
development. If declines are present, age is sometimes not the sole contributing factor.
There is some truth to the saying ?Use it or lose it!!?Contemporary Issues in Cognitive
Development across the Life SpanDuring the latter half of the 20th century, cognitive
developmental psychologists turned their attention to investigating the following issues and
questions.What is the relationship between brain development and cognitive development?
On the one hand, the specific focus has been to identify how brain changes (e.g., structure,
function) influence language and other cognitive capabilities. On the other hand,
researchers are beginning to explore and specify the brain changes that contribute to
intellectual decline in old age. During the 21st century this area has been a hot topic for
researchers in cognitive development.In addition to the focus on brain changes and
cognitive development, researchers are continuing to explore the role of social influences
on cognitive development. The works of the late Russian theorist Lev Semonvich Vygotsky
have contributed to this interest. Researchers are particularly concerned with investigating
how social and cultural influences shape cognitive development early in life and how social
and cultural influences have a continued effect on cognitive development throughout the
life span.Theory of the mind reemerged in the latter half of the 20th century and the
beginning of the 21st century as a topic of interest for cognitive developmentalists. Such
questions as how do children understand the intentions of others and how do children
develop an understanding of the critical aspects of human thinking and behavior have
occupied a central focus in the area of social cognition in the past decade.Finally, the area of
eyewitness testimony continues to have a prominent place in the field of cognitive
development in the 21st century. Researchers are exploring ways to reduce the influence of
interviewer suggestibility on eyewitness testimony and to increase the accuracy of
eyewitness testimony of both adults and young children.Yvette R. HarrisFlavell, J., Miller, P.
