One hundred-eighty college-bound high school seniors were studied to determine whether small group counseling would affect their anxiety level. 60 students comprised the experimental group and 60 students each the 2 control groups. 6 small group counseling sessions were conducted during the spring just prior to high school graduation and 6 more in the fall, following college enrollment. Comparison of anxiety levels was made at the conclusion of each series of counseling sessions. The students of the experimental group showed significantly lower anxiety scores than did those of the control groups, both in the spring and in the fall. The conclusion was drawn that experience in small group counseling was followed by significantly lower levels of anxiety in transitional adolescents.  相似文献

Two recommendations from a recent statement of standards for counselor education are examined for underlying philosophical assumptions. The first recommendation, that counselors should possess ability for and conduct scientific research, assumes that the counseling process is lawful and orderly, that theoretical concepts can be operationally defined and that empirically testable predictions can be derived from counseling theories. A second recommendation suggests that counselors-in-training be selectively admitted and retained. Underlying this recommendation is the assumption that counseling is a process of influence that can be evaluated. Such evaluation must be based on conditions outside the counseling relationship, in the social context of the life of the client. The serious implications of these assumptions are illustrated and discussed.  相似文献

Old (7 months of age) and young (2 months) male rats were divided into groups matched for spontaneous exploratory activity and for age. Experimental rats in the two age categories were then traumatized by giving them a 90 volt shock to the feet for two sec. on only one occasion. It was shown that nearly all the young rats recovered from the trauma within 5 weeks, as measured by brief exploratory activity and defecation, while at the end of 6 months the old rats still had not recovered. These results point up the greater resiliency of young animals, and the need for caution in the interpreting of research and theories on early experience.  相似文献

Observers attempted to detect the presence of a pitch difference between two successive tones. The percentage of correct judgments was equivalent for tones separated by .95, 4.5, and 8.9 sec. There was a general increase in reports of a pitch difference with increased intertone interval, which is interpreted as arising from hypothesized shifts in the neural locus of the first stimulus during the intertone interval.  相似文献
