T-group
n.
training group: a type of experiential group, usually of a dozen or so people, concerned with fostering attitude change and the development of “basic skills,” such as effective leadership and communication. T-group training was developed by the National Training Laboratory in Group Development in the late 1940s and grew out of Kurt Lewin’s work in the area of small-group dynamics. Although the term is sometimes used synonymously with encounter group, the emphasis in a T-group is less on personal growth and more on sensitivity training and practical interpersonal skills, (e.g., as stressed in management training). One of the goals of T-groups is to foster greater understanding of group dynamics and of the individual members’ roles within the group or organization.
