Let's look at the following examples.
Introduced by Sigmund Freud, this theory holds that having a healthy adult personality hinges upon the satisfaction and completion of each previous stage in psychosexual development. Freud was one of the first proponents of how early childhood experiences can shape adulthood personalities.
Theory of Psychosocial Development
Elaborating upon the theory of Sigmund Freud, Erik Erikson focused on a different area of child development, namely, "socio-emotional milestones" (Huitt, 2008).
According to Erikson, each stage of human life has certain points of conflict, wherein they must succeed to feel adequate. The failure to succeed in such a conflict can be a potential cause of the crisis. The theory of psychosocial development was highly regarded during the 20th century, due to its ability to interpret the growth and changes across an individual's total lifespan.
Behavioral Child Development Theory
There are several developmental psychologists who believe external stimuli can shape human behavior. Behaviorism, or the Behavioral Child Development Theory as introduced by John Watson seeks to explain that human development is an overall result of positive and negative reinforcements. These reinforcements, such as rewards and punishments, can strengthen or weaken certain behaviors throughout the course of human life.
Cognitive Development Theory
Jean Piaget introduced the concept of cognitive development as a pillar of human growth and change. According to this theory, there are certain ways that children learn to think across different age ranges.
Starting from relying on sensory experiences and motor skills, children move from concrete thinking towards the understanding of abstract concepts.
Attachment Theory
John Bowlby explained that children develop certain types of attachment with their caregivers. According to Attachment Theory, children have an innate need to feel secure and attached to their caregivers, who in turn provide them with care and support.
The types of attachments formed throughout childhood lead to the kind of adults relationships that individuals will form later in life.

Social Learning Theory
Social Learning Theory was proposed by Albert Bandura as an expansion of Behaviorism. He believed that reinforcements do not fully explain growth and changes in humans; it also occurs through observing others' behaviors.
Bandura stated that motivations for learning do not necessarily need classic conditioning interactions, but also observation of others within the social context. Children can learn from their parents, teachers, peers, and other people in their environment spontaneously, without the need for direct reinforcements.
Sociocultural Theory
Sociocultural Theory by Lev Vygotsky states that learning is deeply embedded in social experiences. Children learn best when they are given hands-on experiences. This is where individuals form paradigms about their understanding of the world.
Vygotsky also explained that there is a Zone of Proximal Development in the learning process; a stage where an individual can learn something with assistance, until they can master it on their own. This concept has influenced many educators on how teaching methods can be improved.
Major Issues in Developmental Psychology
Many of the theories mentioned above were proposed in response to the major issues within developmental psychology. These issues include:
Effect of Genetic and Environmental Factors on Human Development
Developmental psychologists have long been debating if human development is a result of nature vs. nurture. A lot of the theories explain the importance of the environment, social experiences, and resolving conflict, which displays the importance of "nurture" in developmental psychology.
However, it is hard to deny that genetic factors also play a role in human growth, as evolutionary developmental psychology holds. Certain genetic adaptations were necessary throughout the course of evolution; these are evident in human development. Hereditary conditions such as disabilities and diseases also impact lifespan and the developmental process.
Pace of Human Development
A lot of earlier theories supported the separation of each stage in human development, but more recent understanding shows that there is evidence for continuous change. Psychology shows us that there are some aspects of growth and change that are gradual, such as puberty, or cognitive development during infancy.
Other supporting theories show us that external stimuli such as experiences can also continuously shape our personalities, which is outside the bounds of the life stages explained by earlier beliefs.
Personality Change
Certain personality traits are believed to be ingrained from infancy, such as those observed within child temperament psychology. Some theories also explain (directly and indirectly) how environment shapes personality, as laid out in social learning, behaviorism, and caregiver attachment.
Developmental Psychology: Understanding the Spectrum of Human Growth and Change
Developmental psychology is a branch of the discipline that is crucial in understanding growth and changes across an individual's lifespan. By understanding theories in development, how we learn, and how we are shaped by genetics and external influences, we get a deeper sense of the full spectrum of human growth and change.
Developmental Psychology - Key takeaways
- Developmental Psychology is a branch of the discipline that dissects the changes that happen throughout human life.
- The domains of developmental psychology are Physical, Cognitive, Socio-emotional, and Language.
- The theories in human development explain the various ways individuals change as a result of environmental factors, genetic traits, as well as the stages of maturity found in each domain.
- The three major issues in developmental psychology include how genetic or environmental influences affect human growth and change, how development is gradual or continuous across the lifespan, and how personality traits are stable or changing throughout life.
