When 72 male students in a southern theological institution were compared by the manner in which they intended to fulfill their religious vocation (i.e., as missionaries, pastors, or religious education workers), a homogeneity of personality behavior was observed on each of 16 factors. The total sample, however, was reported to be substantially and significantly different from the general population on four factors. No significant difference was reported among the three groups in their need for social approval as measured by the Marlowe-Crowne SDS.  相似文献

Some previous publications have indicated that the creative skills of chemists tend to decline once they are past their thirties or early forties. These conclusions have been based on such criteria of creativity as merit ratings, citations in the literature, etc. In the present study, patent records for all 89 professional men (mostly chemists and chemical engineers) in one division of a large industrial scientific organization were analyzed to determine whether creativity as measured by the production of patentable ideas tended to decrease with age, to increase, or to remain about the same. In the statistical treatment of data both longitudinal and cross-sectional methods were used. All the results were consistent in revealing no decline in creative productivity with increase in age, and indicated instead a tendency for productivity to increase as chemists mature.  相似文献

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
