The extent to which people need or indeed are able to use personal relationships is found in the literature in various different forms. In the field of applied psychology an early distinction was made between person-oriented and task-oriented group leaders and a theory of group behaviour in the work situation was built around this (Fiedler, 1967). The work of Eysenck and others on extraversion–introversion is extremely well known (e.g. Eysenck & Eysenck, 1985). The tradition started by Murray (1938) and continued by McClelland and others (Atkinson, 1958) of describing peoples' needs and motives has led to work on the need for power and the need for intimacy (McAdams et al., 1984).
