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.
Albert Bandura’s concept of Self-efficacy, or confidence as it is commonly known, is one of the most enabling psychology models to have been adopted into positive psychology.
Self-efficacy is an individual’s optimistic belief in their innate ability, competence or chances of succesfully accomplishing a task and producing a favorable outcome.
