KIRKPATRICK'S LEVELS OF TRAINING CRITERIA: THIRTY YEARS LATER   总被引:2,自引:0,他引:2  
Kirkpatrick's model (1959a, 1959b, 1960a, 1960b) of training evaluation criteria has had widespread and enduring popularity. This model proposed four "levels" of training evaluation criteria: reactions, learning, behavior, and results. Three problematic assumptions of the model may be identified: (1) The levels are arranged in ascending order of information provided. (2) The levels are causally linked. (3) The levels are positively intercorrelated. This article examines the validity of these assumptions, the frequency of each level in published evaluation studies, correlations from the literature in regard to Assumptions 2 and 3, and implications for the researcher and training manager.  相似文献

This field study used the Job Feedback Survey (Herold & Parsons, 1985) and performance data gathered from multiple sources to examine the relationship between the perceived organizational feedback environment and performance. Regression analyses indicated that, while holding the other feedback variables constant, feedback from supervisory and organizational sources was related to reported job performance while feedback from peers and self was not. Most of the unique variance in performance explained by feedback was also accounted for by feedback from organizational and supervisory sources. Negative expressions from organizational/supervisory sources (e.g., the supervisor expressing anger, the company communicating dissatisfaction with poor performance) were related to lower performance, and positive job changes initiated by these sources (e.g., increasing responsibility, assignment to special jobs) were related to higher performance. Higher performers did not receive more feedback than lower performers but did receive more total positive feedback. Supplemental issues, possible explanations, and implications of the findings are discussed.  相似文献

Literature since the last comprehensive review of research on the employment interview is summarized, and suggestions for future studies in this area are described. Major changes in findings regarding the validity of the interview, the impact of applicant sex, and the effect of interviewer characteristics/behavior on applicant reactions, as well as other issues, are reported. Contrary to the widely held belief that the interview has low validity, recent research indicates at least modest validity for this selection tool. Conversely, the effect of the campus interview on applicant reactions has been seriously questioned. Researchers are urged to examine several areas in social psychology, including the literature on attitudes-intentions-behavior, the elaboration likelihood model, and theories of discrimination to achieve greater understanding of the employment interview.  相似文献

In this article, the experience of conversion, which is usually delegated to the realm of spiritual studies, is applied to the counseling experience. It is posited that a person who goes through a successful counseling process will experience a turning around, will cease leading life in a dysfunctional way, and will move forward in a manner by which the person experiences life in a new perspective. This new perspective brings the person wholeness and balance.  相似文献

The 16th century schism in Christian thought leading to the Reformation has an interesting analogy in Carl Rogers' attempt to reform the helping professions. An exploration of this analogy clarifies much of the theoretical tension in the contemporary arena of pastoral counseling.  相似文献

When a formant transition and the remainder of a syllable are presented to subjects' opposite ears, most subjects perceive two simultaneous sounds: a syllable and a nonspeech chirp. It has been demonstrated that, when the remainder of the syllable (base) is kept unchanged, the identity of the perceived syllable will depend on the kind of transition presented at the opposite ear. This phenomenon, called duplex perception, has been interpreted as the result of the independent operation of two perceptual systems or modes, the phonetic and the auditory mode. In the present experiments, listeners were required to identify and discriminate such duplex syllables. In some conditions, the isolated transition was embedded in a temporal sequence of capturing transitions sent to the same ear. This streaming procedure significantly weakened the contribution of the transition to the perceived phonetic identity of the syllable. It is likely that the sequential integration of the isolated transition into a sequence of capturing transitions affected its fusion with the contralateral base. This finding contrasts with the idea that the auditory and phonetic processes are operating independently of each other. The capturing effect seems to be more consistent with the hypothesis that duplex perception occurs in the presence of conflicting cues for the segregation and the integration of the isolated transition with the base.  相似文献

The continuous approach to optic-flow processing shows that the curvature of a moving surface is related to a second spatial derivative of the velocity field, the spin variation (Droulez & Cornilleau-Pérès, 1989). With this approach as a theoretical framework, visual sensitivity to the curvature of a cylinder in motion was measured using a task of discrimination between cylindrical and planar patches. The results confirm the predictions suggested by the theory: (1) Sensitivity to curvature was always greater when the cylinder axis and the frontal translation were parallel than when they were orthogonal. The ratio of curvature detection thresholds in the two cases was between 1.3 and 2.5; the value predicted from the spin variation theory is about 2. (2) Sensitivity to curvature increased strongly with the velocity of the motion but was only weakly affected by its amplitude and the duration of viewing for the range of values used in our experiments.  相似文献
