不同自我评价方式对高中生写作的影响

本研究考察了三种不同的自我评价方式对高中二年级学生写作活动的影响。结果表明,自我评价对写作成绩有一定改善,但短期内对一般性的学习动机与效能感无显著影响。写作结果自我评价方式有助于写作结果自我评价准确性的提高,单独的写作过程自我评价方式短期内对写作活动无显著促进作用,写作结果与写作过程的综合自我评价方式显著改善了写作活动。     

Diminishing marginal value as delay discounting.

The fundamental law underlying economic demand and exchange is the tendency for value of marginal units to diminish with increasing amounts of a commodity. The present paper demonstrates that this law follows from three still-more-basic psychological assumptions: (a) limited consumption rate, (b) delay discounting, and (c) choice of highest valued alternative. Cases of diminishing marginal value apparently due to pure intensity of reward may plausibly be attributed to the above three factors. The further assumption that maximum consumption rate may vary within and across individuals implies that some substances may be unusually addictive and that some individual animals may be unusually susceptible to addiction.     

Preconceptional family health evaluation: A regional education program for family planning clients and health professionals

The Preconceptional Family Health Evaluation Program was a regional project developed and funded for 2 years by the New England Regional Genetics Group (NERGG) to educate family planning health professionals about genetics, and to offer family planning clients preconceptional identification of genetic and environmental exposure risks. To meet these goals, genetic education was provided on a regional basis to 45 family planning professionals. A self-administered family health risk questionnaire adaptable to individual family planning settings was developed. Five hundred and twenty-nine family planning clients voluntarily completed the questionnaire. Cigarette smoking (35%) and alcohol use (57%) were two major categories of risks identified. The Preconceptional Family Health Evaluation Program was well received by all participants and provided an effective means for regional education of family planning health professionals. As a result of the program, state program planners, clinical genetics services, and family planning health professionals developed a strong relationship that will serve future educational and genetic risk screening efforts.     

Acceleration model in the heterogeneous case of the general graded response model

A new model, called acceleration model, is proposed in the framework of the heterogenous case of the graded response model, based on processing functions defined for a finite or enumerable number of steps. The model is expected to be useful in cognitive assessment, as well as in more traditional areas of application of latent trait models. Criteria for evaluating models are proposed, and soundness and robustness of the acceleration model are discussed. Graded response models based on individual choice behavior are also discussed, and criticisms on model selection in terms of fitnesses of models to the data are also given.This research was supported by the Office of Naval Research (N00014-90-J-1456).     

试论反应性抑郁形成的心理过程

对反应性抑郁形成的心理过程进行解释的理论中 ,较有影响的有精神分析理论、控制理论、认知理论、自我注意理论和行为主义理论。由于这些理论都仅强调某一个因素的作用 ,因而有一定的局限性。如果综合考虑这些因素 ,同时还考虑到评价、个体扮演角色的多少及其采用的应付方式等因素的作用 ,就可以看出反应性抑郁形成的完整心理过程。     

Blending qualitative and behavior analytic research methods to evaluate outcomes in inclusive schools

Following Haring's (1992) recommendation, we have utilized qualitative research techniques to assist us in designing a program of research on inclusive education which is responsive to the outcome values and priorities identified by teachers and parents. Using interviews, observations, and document analysis to follow 35 children in full inclusion classrooms over a period of two years, we have described outcomes for these children in three major domains. These outcome domains, and subthemes within them, have been evaluated and revised based on interviews and social validation ratings by parents and teachers. Dependent measures based on our qualitative research findings are currently being used in a series of behavior analytic studies designed to evaluate the effects of specific interventions on outcomes of inclusion for children with and without disabilities.     

Objective assessments of quality of life: How much do they agree with each other?

Information was collected on 14 objective measures of service quality in 15 staffed houses for people with learning disabilities. Measures or dimensions of the measures were grouped under six headings: (1) quality of housing; (2) social and community integration; (3) social interactions; (4) development; (5) activity; and (6) autonomy and choice. Rank order correlation coefficients were calculated to explore the extent to which different quality assessments within each category agreed. Overall, there was a reassuring level of agreement. Some of the lack of agreement found could be attributed to the fact that, even though addressing the same general area, measures were focused on subtly different facets of the phenomenon under study. Other disagreement seemed to stem from the interaction between the nature of the information and the process for obtaining it. Comparisons between measures which required staff to give an opinion about how the setting was organized, and those which either required staff to comment on resident activity or employed independent observation, tended to disagree. The study illustrates that the basis for translating a multidimensional definition of quality into measurable terms is developing. Further research to examine the interrelationship between measurement approaches is warranted.     

The Effects of a Self-sacrificing Minority on Pro-environmental Norms and Behavior: An Investigation Using a Sea Pollution Game

This research investigated how a minority member sacrificing his/her personal benefits to protect the environment might influence the attitudes and behavior of others. The experiment, using a sea pollution game, employed a 2(minority factor)×2(cost factor) factorial design. Under the high-cost condition, in which an ecological minority bears the substantial cost it was hypothesized that the rate of subjects' pro-environmental behavior would be higher in the one-minority case than in the no-minority case. In contrast, under the low-cost condition, the differences between these two cases would decrease. The results supported this assumption. In prompting pro-environmental behavior, a self-sacrification minority member is more influential than one whose behavior is not self-sacrificing. Moreover, under the one-minority condition, path analyses indicated that the subjects' cost evaluation did not affect their behavior. It was concluded that when the subjects saw an ecological minority, the inhibiting effects of cost on their pro-environmental behavior would decrease.     

Application of model-selection criteria to some problems in multivariate analysis

A review of model-selection criteria is presented, with a view toward showing their similarities. It is suggested that some problems treated by sequences of hypothesis tests may be more expeditiously treated by the application of model-selection criteria. Consideration is given to application of model-selection criteria to some problems of multivariate analysis, especially the clustering of variables, factor analysis and, more generally, describing a complex of variables.     

AN ANALYSIS OF THE PROCEDURAL COMPONENTS OF SUPPORTED EMPLOYMENT PROGRAMS ASSOCIATED WITH EMPLOYMENT OUTCOMES

This study examined the relation between the procedural components of supported employment programs and employment outcomes for 120 individuals with disabilities. These individuals were involved in supported employment programs established through the Utah Supported Employment Project. The results suggest that successful implementation of supported employment services led to ongoing employment of study participants in community work sites, increased wages, and ongoing opportunities for workers to interact with nondisabled peers. In addition, several procedural components were found to be strongly associated with successful employment outcomes for workers. Results of the study are discussed in terms of the training needs of supported employment program staff and future research for the dissemination of a cohesive technology of supported employment.
