Sigmund Freud’s Stages of Psychosexual Development

Sigmund Freud is regarded as the father of psychodynamic theories, the founder of psychoanalysis and the creator of psychosexual stages theory of human development. Regardless of the acceptance or disapproval of his ideas about human development, his influence over psychology was enormous. During a puritan era he managed to construct a theory of unconscious motivation, of human sexuality and instinctual aggression.

Erik Erikson’s Stages of Psychosocial Development

Erikson was a stage theorist who took Freud’s controversial theory of psychosexual development and modified it as a psychosocial theory, as he rejected the central importance of the sexual drive in favour of the progressive emergence of identity. Like Freud and many others, Erik Erikson maintained that personality develops in a predetermined order, and builds upon each previous stage. This is called the epigenetic principle.

Jerome Bruner’s Constructivist Theory of Development

The American psychologist Jerome S. Bruner, strongly influenced by the work of Russian psychologist Lev Vygostky, further developed and applied his ideas in the field of education. Bruner declared that Vygotsky has convinced him about the impossibility of understanding the concept of human development in any other way than as a process of assistance, of collaboration between child and adult, where the adult is taking up the role of a sociocultural mediator. Due to its distinct features, we consider the theory to be a sociocultural constructivist one.

The Social Genetic Model of Cognitive Development

During the 1970′, at Geneva, a new perspective on cognitive development has begun to emerge. The self-defined school of socio-genetical psychology advanced theories that represented a challenge addressed to the spirit of genetical epistemology.

Willem Doise, Gabriel Mugny and Jean Claude Deschamp, to name but a few of the representatives, declare that social interactions constitute the privileged setting which gives birth to the intellectual acquisitions of the child. There is a direct cause and effect link between social interaction and individual cognitive development.

Lev Vygotsky’s Theory of Social Development

The work of Lev Vygotsky (1934) has become the foundation of much research and theory in cognitive development over the past several decades, particularly of what has become known as Social Development Theory.

Vygotsky’s theories stress the fundamental role of social interaction in the development of cognition (Vygotsky, 1978), as he believed strongly that community plays a central role in the process of “making meaning.”

Jean Piaget’s Theory of Cognitive Development

Jean Piaget’s theory of cognitive development (1935) explains how a child constructs a mental model of the world. He disagreed with the idea that intelligence was a fixed trait, and regarded cognitive development as a process which occurs due to biological maturation and interaction with the environment.

Jean Piaget’s take on learning, viewed as a modification in the state of knowledge, coherently integrates itself in the group of piagetian research on the subject of intelligence development.
