Development Of Human Behavior: Types, Stages, Factors, Characteristics, Theories And More!

The development of human behavior looks at how people act and think from birth through adulthood. It shows how our behavior changes as we grow. Behavior includes things we do, like walking and talking. It also includes thoughts and feelings. Scientists study the development of human behavior to understand how we learn and change over time.

What is Human Behavior? 

Human behavior is everything people do and say. It includes actions like walking, talking, working, and playing. Behavior also means thoughts, feelings, beliefs, and attitudes. How humans behave is what makes us human. Studying behavior helps understand people and the relationships between individuals.

Types of Human Behavior

There are different types of behaviors:

• Cognitive behaviors are thinking, problem-solving, and decision-making in the brain.
• Emotional behaviors are expressions of feelings like joy, anger, and sadness through facial expressions or body language.
• Social behaviors are interactions with others like cooperation, communication, and relationships.
• Motor behaviors use the body, like posture, movement, handwriting, and sports skills.
• Habitual behaviors are routines people learn and repeat often without much thought.
• Voluntary behaviors are under conscious control and change more easily than habits.
• Involuntary behaviors happen without direct control, like heartbeat and digestion.

Stages of Development

Developmental scientists describe the typical progression of behavior change from birth to adulthood as occurring through distinct stages:

Infancy (Birth to 2 years): During this foundational stage, babies are focused on exploring their world through their senses. They begin developing motor skills like rolling over, sitting up, crawling, and walking. Important social and emotional milestones happen, too, as babies bond with caregivers, recognize familiar faces, express emotions, and understand they are separate beings. Their brains are rapidly developing to lay the groundwork for future learning.

Early childhood (2 to 6 years): Also called the preschool years, this is a time of increased independence and social interaction. Children gain more control over their bodies and behaviors while enjoying energetic play. They start make-believe games, cooperate with peers, communicate their needs verbally, and understand basic rules. Major cognitive leaps occur in early childhood, with Piaget's pre-operational thought emerging.

Middle Childhood (6 to 11 years): Formal schooling begins during the grade school years. Children develop stronger self-control, focus, and problem-solving skills. Their behavior centers around schoolwork, extracurricular activities, and expanding friendships. A growing understanding of social norms and deeper emotions like pride/shame emerge. Morality continues developing beyond simple obedience as kids consider fairness and people's intentions behind actions.

Adolescence (11 to 18 years): Puberty transforms the body during the teen years while friendships and identity formation take center stage. Teens challenge rules to separate from parents and learn independent decision-making. More advanced perspective-taking, abstract thinking, and future-oriented goals reflect their cognitive maturation. New behaviors show their evolving independence within social contexts.

These stages roughly outline common sequences in many domains of development, like physical, cognitive, social-emotional, and motor skills. However, individuals may progress through them at varied rates depending on their unique experiences, traits, and environments. Understanding typical stages provides context for healthy growth.

Factors that Influence Development

Many things affect the development of human behavior:

• Biology: Genes and brain development impact abilities and traits.
• Environment: Family, school, and culture/society around a child affect learning.
• Experiences: Interacting with peers, technologies, and the world teaches behavior.
• Psychology: Developing skills like thinking, memory, emotions, and language abilities.

The interplay between these factors—nature and nurture—shapes how behavior changes as people grow up. Both biology and experience are important.

Characteristics of Human Behavior

Typical attributes include:

• Purposeful or goal-directed: Behaviors aim to satisfy needs, achieve wants, or avoid harms.
• Observable: Behaviors can be watched, recorded, and described objectively, unlike private thoughts.
• Dynamic: Behaviors change in response to each situation and over time with development.
• Influenced by past experiences: Prior learning alters future behavioral choices.
• Varied: Culture and genetics make every person's behaviors unique to some degree.
• Social context: The presence of others usually impacts behaviors in many species.
• Complex: Many behaviors result from combinations of underlying factors hard to simplify.

Key Theories of Development

Several influential developmental theories provide frameworks to understand how and why human behavior changes over time:

Piaget's Stages of Cognitive Development: The pioneering work of Jean Piaget proposed that children progress through distinct stages of how they think and understand the world. He described sensorimotor, pre-operational, concrete operational, and formal operational stages where logical reasoning abilities expand from basic actions to abstract logic. Piaget's theory highlighted how children are active learners constructing knowledge from their experiences.

Erikson's Stages of Psychosocial Development: Erik Erikson built upon Piaget's ideas to focus on psychosocial challenges across the lifespan. His theory outlined stages centered around developing trust, autonomy, initiative, industry, identity, intimacy, generativity, and integrity. Successfully navigating age-related psychosocial crises leads to healthy personality development. Erikson emphasized social experiences impact how individuals perceive themselves.

Kohlberg's Stages of Moral Development: Building off Piaget, Lawrence Kohlberg proposed sequential stages where people's understanding of morality progresses in sophistication. He described moving from basic obedience to self-interest, authority-oriented thinking to social conformity, and finally to principled moral reasoning focused on justice and universal ethical principles. Kohlberg's theory aimed to explain patterns in moral judgment development.

These prominent theories shed light on common developmental trajectories but also acknowledged individual differences in rates of progress and environmental influences on behavior. While later revised or expanded upon, they established foundations for developmental science. Subsequent theories have also aimed to incorporate influences of culture, gender, and cognitive neuroscience.

Studying the Development of Behavior

It is studied through various research methods over time, including:

• Longitudinal studies: Observing the same people repeatedly from childhood to adulthood.
• Observational studies: Watching babies kids in natural settings using coding.
• Parent/teacher reports: Tracking development of skills, temperament, and social skills.
• Experiments: Testing theories through controlled comparisons of behavior.
• Interviews: Asking children, teens, and adults to reflect on how they have changed.

Multimethod research helps gain a fuller understanding of the development of human behavior.

Examples of Changes in Behavior

There are many observable examples that illustrate how human behavior progresses as children learn and mature into adults:

Language - Infants begin by cooing and babbling, then say simple words, abbreviate words, and eventually begin speaking in sentences by age two. Throughout childhood, vocabulary and grammar skills rapidly expand into fluent conversation.

Motor Skills - Early on, fine motor control allows babies to grasp toys and feed themselves messy snacks. Toddlers learn to run, jump, throw and catch balls. Physical coordination improves during elementary school to support play. Teenagers may focus on perfecting abilities for sports.

Cognition - As preschoolers, imagination and pretend play emerge. School-aged children learn to problem-solve more logically and retain information for the longer term. Younger teens display more nuanced critical thinking where they strategize and consider multiple viewpoints.

Emotional Regulation - Highly emotional reactions are typical for infants to express themselves. Over time, children control impulses better and understand diverse emotions. Teenagers can reflect inward on their identity and handle challenging feelings in socially acceptable ways.

Social Behavior - Parallel play occurs among babies near one another. Cooperative group activities develop as preschoolers make friends. Elementary kids gather in clubs and circles of friends. Teen relationships center around intimate self-disclosure, loyalty, and appropriate relationship boundaries with peers and dating partners.

These changes reflect growing skills and advancing brains as the behaviors of humans become more complex, sophisticated and mature throughout development. Careful studies continue expanding knowledge of this fascinating lifelong unfolding.

Overall, the development of human behavior shows kids constantly learning throughout childhood and beyond into adulthood based on their biology and environment. Their behaviors become more complex over time.

Conclusion

In summary, the development of human behavior is a lifelong process showing how thoughts, feelings, and actions change as people mature physically and mentally across stages of life. Careful research helps explain influences on this fascinating journey from infancy to adulthood using theory and diverse methods over many years. Understanding its progression better serves children's healthy growth.
