Understanding Developmental Psychology

Change is inevitable. As humans, we constantly grow throughout our lifespans, from conception to death (or 'womb to tomb'). The field of developmental psychology explores the physical, cognitive, emotional, and social changes that happen as people age.

Psychologists strive to understand and explain how and why people change throughout life. While many of these changes are normal and expected, they can still pose challenges that people sometimes need extra assistance to manage.

The principles of normative development with specific milestones help professionals spot potential problems and provide early intervention for better outcomes. Developmental psychologists can work with people of all ages to address roadblocks and support growth. However, some choose to specialize in a specific age group, such as childhood, adulthood, or old age.

Lifespan Development: How We Grow and Change Over the Years

Those who specialize in this field are not just concerned with the physical changes that occur as people grow; they also look at the cognitive, emotional, and social development that occurs throughout life.

Some of the many issues developmental psychologists assist with include:

• Cognitive development during childhood and throughout life
• Developmental challenges and learning disabilities
• Emotional development
• Language acquisition
• Moral reasoning
• Motor skill development
• Personality development
• Self-awareness and self-concept
• Social and cultural influences on child development

These professionals spend a great deal of time investigating and observing how these processes occur under normal circumstances. Still, they are also interested in learning about things that can disrupt developmental processes.

Developmental Psychology Theories

Developmental psychologists often consider a wide array of theories to consider different aspects of human development. A few examples are listed below:

• Cognitive development. A psychologist assessing intellectual growth in a child might consider Jean Piaget's theory of cognitive development, which outlines the key stages children go through as they grow and learn.
• Attachment. A psychologist working with a child might also want to consider how the child's relationships with caregivers influence their behaviors, so they might turn to John Bowlby's theory of attachment.
• Personality. Sigmund Freud's psychosexual theory of personality development is another influential theory that explains the importance of childhood experiences on personality development and how maladaptive coping styles and defense mechanisms emerge.
• Social and emotional growth. Psychologists are also interested in looking at how social relationships influence children's and adults' development. Erik Erikson's theory of psychosocial development and Lev Vygotsky's theory of sociocultural development are two popular theoretical frameworks that address the social influences on the developmental process.

Each approach tends to stress different aspects of development, such as mental, parental, social, or environmental influences on children's growth and progress.

Developmental Psychology Stages

As you might imagine, developmental psychologists often break down development according to various phases of life. Each of these periods of development represents a time when different milestones are typically achieved.

People may face particular challenges at each point, and developmental psychologists can often help people who might be struggling with problems to get back on track.

Prenatal Development

Developmental psychologists are interested in the prenatal period, seeking to understand how the earliest influences on development can impact later growth during childhood. They may examine how primary reflexes emerge before birth, how fetuses respond to stimuli in the womb, and the sensations and perceptions that fetuses are capable of detecting prior to birth.

Developmental psychologists may also look at potential problems such as Down syndrome, maternal drug use, and inherited diseases that might have an impact on the course of future development.

Early Childhood Development

The period from infancy through early childhood is a time of remarkable growth and change. Developmental psychologists examine the physical, cognitive, and socio-emotional growth during this critical development period.

In addition to providing interventions for potential developmental problems at this point, psychologists are also focused on helping kids achieve their full potential. Parents and healthcare experts are often on the lookout to ensure that kids are growing properly, receiving adequate nutrition, and achieving cognitive milestones appropriate for their age.

Middle Childhood Development

This period of development is marked by both physical maturation and the increased importance of social influences as children make their way through elementary school.

Kids begin to make their mark on the world as they build their unique sense of self, form friendships, grasp principles of logic, and gain competency through schoolwork and personal interests. Parents may seek the assistance of a developmental psychologist to help kids deal with potential problems that might arise at this age, including academic, social, emotional, and mental health issues.

Adolescent Development

The teenage years are often the subject of considerable interest as children experience the psychological turmoil and transition that often accompanies this period of development. Psychologists such as Erik Erikson were especially interested in looking at how navigating this period leads to identity formation.

At this age, kids often test limits and explore new identities as they question who they are and who they want to be. Developmental psychologists can help support teens as they deal with some of the challenging issues unique to the adolescent period, including puberty, emotional turmoil, and social pressure.

Early Adult Development

This period of life is often marked by forming and maintaining relationships. Critical milestones during early adulthood may include forming bonds, intimacy, close friendships, and starting a family and career.

Those who can build and sustain such relationships tend to experience connectedness and social support, while those who struggle with such relationships may feel alienated and lonely.

Middle Adult Development

This stage of life tends to center on developing a sense of purpose and contributing to society. Erikson described this as the conflict between generativity and stagnation.

Those who engage in the world, contribute things that will outlast them, and leave a mark on the next generation emerge with a sense of purpose. Activities such as careers, families, group memberships, and community involvement are all things that can contribute to this feeling of generativity.

Older Adult Development

The senior years are often viewed as a period of poor health, yet many older adults can remain active and busy well into their 80s and 90s. Increased health concerns mark this period of development, and some individuals may experience mental declines related to dementia.

Theorist Erik Erikson also viewed the elder years as a time of reflecting back on life. Those who can look back and see a life well-lived emerge with a sense of wisdom and readiness to face the end of their lives, while those who look back with regret may be left with feelings of bitterness and despair.

When to See a Developmental Psychologist

While development tends to follow a fairly predictable pattern, there are times when things might go off course. Parents often focus on what are known as developmental milestones, which represent abilities that most children tend to display by a certain point in development. These typically focus on each of four main areas:

• Physical milestones
• Cognitive milestones, including language development
• Emotional milestones
• Social milestones

For example, walking is one physical milestone most children achieve between 9 and 15 months. If a child is not walking or attempting to walk by 16 to 18 months, parents might consider consulting with their family physician to determine if a developmental issue might be present.

By being aware of these milestones, parents can seek assistance, and healthcare professionals can offer interventions to help kids overcome developmental delays.

These professionals often evaluate children to determine if a developmental delay might be present, or they might work with elderly patients who are facing health concerns associated with old age, such as cognitive declines, physical struggles, emotional difficulties, or degenerative brain disorders.

Diagnosing Developmental Issues

To determine if a developmental problem is present, a psychologist or other highly trained professional may administer a developmental screening or evaluation.

For children, such an evaluation typically involves interviews with parents and other caregivers to learn about behaviors they may have observed, a review of a child's medical history, and standardized testing to measure functioning in terms of physical and motor development, cognitive skills, language development and communication skills, and social/emotional skills.

If a problem is found, the patient may be referred to a specialist, such as a speech-language pathologist, physical therapist, or occupational therapist.

Coping With a Developmental Diagnosis

Receiving a diagnosis of a developmental issue can often feel both confusing and frightening, particularly when you, your own child, or an elderly parent is affected. Once you or your loved one has received a diagnosis of a developmental issue, spend some time learning as much as you can about the diagnosis and available treatments.

Prepare a list of questions and concerns you may have and discuss these issues with your doctor, developmental psychologist, and other healthcare professionals who may be part of the treatment team. By taking an active role in the process, you will feel better informed and equipped to tackle the next steps in the treatment process.
