Investigations of a mirror-image transfer effect in pigeons   总被引:2,自引:1,他引:1       下载免费PDF全文
In two separate experiments, pigeons trained binocularly to peck a key on which an oblique line (e.g., 60 degrees counter-clockwise rotation from horizontal) was projected yielded bi-modal angularity generalization gradients in extinction, with peaks of responding at both the training stimulus and its mirror image (in this case 120 degrees ). This mirror-image transfer effect may be analogous to an "octave effect" in auditory generalization, but Mello's finding of a mirror-image reversal transfer effect following monocular training in pigeons suggests an alternative interpretation.  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
