Physically disabled and non-disabled high school seniors' educational and vocational aspiration-expectation discrepancies were compared. No significant differences were found when the two groups were matched for cumulative GPA and level of father's occupation. GPA's and father's job levels of disabled students were significantly lower than those of the non-disabled. When not matched, disabled students' vocational aspiration-expectation discrepancies were significantly higher than those of the non-disabled. Higher aspiration than expectation for the highest vocational and educational levels, professional training, and employment were the major sources of differences expressed by seniors. 相似文献

Three keys were available for monkeys to press. The objective was to teach the animals to press the keys in sequences up to 10 members in length. With fading procedures, a light that cued the correct key at a given serial member of the sequence faded out slightly each time the animal selected it, and became slightly brighter after the animal made an error at that sequence member. The correct keys were faded out, starting from the end of the sequence and proceeding toward the beginning. With control procedures, the cue lights were turned off suddenly, rather than being faded gradually. In almost every instance, the animals learned a longer series of unlighted key positions with the fading procedures than they did when each key-light was turned off suddenly. Also, requiring the animals to press a series of keys cued by lights before they could reach the sequence members they were to learn hampered them in learning the later serial members. By using several different sequences, it was possible to replicate these findings within the individual animal. 相似文献
