Cognitive theories of development emerged in the late 1950s and continue to hold prominence today. Cognitive educational psychologists are interested in the internal workings of the mind. Specifically, they seek to understand how processes related to behaviours, thoughts, and emotions are organized in the mind of an individual and how they change with age and experience.
Many cognitive psychologists (e.g., Jean Piaget, Lawrence Kohlberg, and Benjamin Bloom) argue that cognitive development unfolds in a stage-like manner, dependent upon physical maturation. These theorists posit that the organization of the brain changes with maturation, thereby allowing people to think more abstractly as they get older. While “stage theories” of development are useful for describing cognitive growth, it is important to remember there is great diversity in children’s rates of development – differences that are often linked to social, cultural and genetic differences amongst children.
Social constructivist theories of development that explore the influence of environment on development also began to emerge in the 20th Century. Social constructivist theories of development are built upon the premise that knowledge is an active process, formed in social contexts and shaped by people’s past learning experiences, beliefs, social experiences, and motivations. Social constructivist theorists, such as Albert Bandura, expanded beyond aspects of behaviourism (e.g.,, the concept of reinforcement) to also include social influences on the development of behaviour.
Bandura’s Social Learning Theory posits that knowledge is formed by observing how others (role models) respond to social, emotional. and intellectual events. From Bandura’s point of view, development occurs when people see others performing behaviours. They then attempt to imitate those behaviours themselves in social contexts. Behaviours are encouraged, refined, or discontinued through this process as people receive feedback about their behaviours from their social environments.
Another major contributor to the field of constructivism was Lev Vygotsky. Vygotsky’s Social Cultural Theory views development as socially guided. From this perspective, interactions with others who are supportive and more knowledgeable spurs internal development by guiding learners beyond their current abilities to perform more complex tasks.
Constructivist viewpoints remain popular in the 21st Century. Currently, many educational researchers are expanding on the work of Vygotsky, Bandura, and others by examining how social contexts, learners’ characteristics, and teachers’ characteristics (e.g., beliefs, histories, motivations, and teaching styles) contribute to the development of underlying competencies for learning within diverse contexts.
