Harry Kempen
In the 1990s, Kempen and Hubert Hermans developed a new approach in cultural psychology around the concept of the dialogical self. In 1993, they published the seminal work "The dialogical self: Meaning as movement", and published several articles in "American Psychologist", "Journal of Personality" and "Theory & Psychology". Despite their success Kempen suffered from depression. In 2000, he died in Nijmegen four days before his retirement from the Radboud University. At the university he is remembered by as the "personification of cultural psychology."Articles, a selection:
Morton Deutsch
In 1963 he made what would be his final move between institutions, when he started at Teachers College, Columbia University after being invited to found a new social psychology doctoral program. The two major works that resulted of his studies during this period are considered to be "The Resolution of Conflict" (published in 1973) and "Distributive Justice" (published in 1985). However he also published the book "Theories in Social Psychology" (1965) and "Applying Social Psychology" (1975) during this same period. Deutsch was the first psychologist to use the Prisoner's Dilemma to study trust between small groups or pairings of individuals. During this period his work in conflict resolution continued to grow in influence, including his differentiation between constructive conflict and destructive conflict. The impact of his work was seen both in theory and in practice—for example, in 1989 both Janusz Grzelak (a leading figure of the Solidarity movement in Poland) and Janusz Reykowski (a leading figure of the Communist Party of Poland) cited Deutsch's work as part of the infrastructure for the peaceful transfer of power from the Communists to the people.
