This is a short historical review showing how researchers in the early part of this century attempted to define and measure artistic ability and establish a relationship between such ability and general intelligence. The definition of artistic ability was a recurring difficulty which has not, indeed, been satisfactorily settled yet, although the inadequacy of some of the criteria put forward earlier in the century can now be clearly seen. Such criteria were often wholly convergent, requiring pupils to conform to pre‐established notions of ‘correctness’ which now seem inappropriate to the subject. 相似文献

Communicators achieve increased rule consensus as they use talk to overcome problems. Two kinds of talk seem especially useful to increasing consensus: remedial talk, which uses rules to correct past problems; and legislative talk, which uses rules to propose guides for future conduct. 相似文献

This study investigates four variations of a microtechnology process and its effect on the development of cooperative behavior in 96 third grade children. Subjects were randomly assigned to one of four treatment groups. The treatments were the complete microtechnology process and three variations of the process. Findings suggest that: cooperative behavior can be significantly (p < .01) increased by use of microtechnology techniques; the microtechnology process is effective without the self-confrontation component; and the behavior developed exhibited short-term retention. 相似文献
