Abstract: | Training through observed silent demonstrations was compared with providing equivalent information by verbal instructions, using adult mental retardates of three age and ability levels. At all levels, demonstration surpassed instructions in promoting concept attainment and transfer. During imitation testing, all groups received feedbeck (‘right’ or ‘wrong’) about their responses. Dispensing candy rewards for correct answers did not affect performance. |
