The Theory and Practice of Group Psychotherapy

Learning for Leadership.@@@Personal and Organizational Change Through Group Methods: The Laboratory Approach.

Quantitative relationships were sought among psychomotor response speed (R), number of practice trials (T), chronological age (A), and biological sex (S) for 600 Ss in 30 groups between the ages of 8 and 87 yr. All Ss received 320 trials on a Discrimination Reaction Time apparatus. Hull's equation R = m(1 – e-iT) + c was found capable of describing all 30 acquisition curves with an average predictability of 97.98% when the asymptote (m), rate (i), and R-intercept (c) parameters were varied jointly. When m and c were held constant for each sex and only i varied, the average predictability dropped to 64.76%, indicating that rate alone was inadequate to account for variance due to age and sex. Confirming and extending the classical age-performance data, acquisition speeds followed differential trends for both age and sex variation while over-all proficiency was a non-monotonic function of age. There was a rapid growth to a maximum level for females at the age of 16 and for males at 20, then a gradual, non-pa...

Age and Sex Parameters in Psychomotor Learning

Controlled studies of the outcome of sensitivity training.

The research on group composition for psychotherapeutic and growthoriented groups is reviewed and analyzed. The survey of the literature consists of a sampling of clinical observations and reports and a review of premature termination studies, group-therapy process studies, and laboratory group research. The social microcosm, dissonance, cohesion, and supportplus-confrontation models of group composition are presented and evaluated. Lastly, the findings and their implications for the composition of groups are discussed.
