The effect of various relationships between a response (an investment made in the context of a game) and an outcome (a return
on the investment) on judgments of the causal effectiveness of the response was examined. In Experiment 1, response rates
and causal judgments were higher for a differential-reinforcement-of-high-rate (DRH) schedule relative to a variable-ratio
(VR) schedule with the same probability of outcome following a response. Response rates were also higher for a DRH than for
a variable-interval schedule matched for reinforcement rate. In Experiment 2, response rates and causal judgments were lower
for a differential-reinforcement-of-low-rate schedule relative to a VR schedule with the same probability of outcome following
a response. These results corroborate the view that schedules are a determinant of both response rates and causal judgments,
and that few current theories of causal judgment explicitly predict this pattern of results. 相似文献

Social anxiety in learning is prevalent amongst traditional-age students and has a marked effect on their engagement with higher education. It receives little attention from academic or support services and there is a presumption that students will manage their anxieties. Yet it is unclear what psychosocial resources they might bring to this task and how these may develop through the undergraduate years. This study sought to identify possible change processes in student social anxiety by analysing qualitative responses obtained from Level 2 undergraduate students (n=39) in relation to their experience of learning situations such as lectures, seminars and group presentations. Thematic analysis suggested a four-stage developmental progression for students in terms of their experience and orientation to coping with social anxiety. Implications for staff development and student support are outlined. 相似文献

The purpose of this study was to develop a program to help cultivate divergent thinking in mathematics based on open-ended
problems and to investigate its effect. The participants were 398 seventh grade students attending middle schools in Seoul.
A method of pre- and post-testing was used to measure mainly divergent thinking skills through open-ended problems. The results
indicated that the treatment group students performed better than the comparison students overall on each component of divergent
thinking skills, which includes fluency, flexibility, and originality. The developed program can be a useful resource for
teachers to use in enhancing their students’ creative thinking skills. An open-ended approach in teaching mathematics suggested
in this paper may provide a possible arena for exploring the prospects and possibilities of improving mathematical creativity. 相似文献

Transfer of judgments of control to a target stimulus and to novel stimuli through derived relations
Three experiments examined the effect of response?Coutcome contingencies on human ratings of causal efficacy and demonstrated that such ratings transfer to novel situations through derived stimulus relations. Efficacy ratings generally followed the delta probability rule when positive response-outcome contingencies were employed (Experiment 1) and when some outcomes were not contingent on participants?? responses (Experiment 2). Experiment 3 employed a negative response?Coutcome contingency and manipulated performance expectancies in the task. All three groups overestimated their causal efficacy ratings. A learned helplessness effect was observed when the response?Coutcomes were uncontrollable and in the high-expectancy group when participants?? performance in the task was worse than they had expected. In all experiments, ratings transferred to a stimulus presented during the task and often generalized to novel stimuli through derived relations. These results corroborate the view that outcome probability is a determinant of causal efficacy ratings and that schedules can be employed as UCS in procedures that share characteristics of evaluative conditioning procedures. 相似文献

The purpose of the present study was to identify the mediating effects of emotion regulation on the association between cumulative childhood trauma and behavior problems in sexually abused children in Korea, using structural equation modeling (SEM). Data were collected on 171 children (ages 6–13 years) referred to a public counseling center for sexual abuse in Seoul, Korea. Cumulative childhood traumas were defined on the basis of number of traumas (physical abuse, witnessing domestic violence, neglect, traumatic separation from parent, and sexual abuse) and the severity and duration of traumas. Children were evaluated by their parents on emotion regulation using the Emotion Regulation Checklist and internalizing and externalizing behavior problems using the Korean-Child Behavior Checklist. SEM analyses confirmed the complete mediation model, in which emotion dysregulation fully mediates the relationship between cumulative childhood traumas and internalizing/externalizing behavior problems. These findings indicate that emotion regulation is an important mechanism that can explain the negative effects of cumulative childhood traumas and that there is a need to focus on emotion regulation in sexually abused children exposed to cumulative trauma. 相似文献

Evidencing student achievement of standards is a growing imperative worldwide. Key stakeholders (including current and prospective students, government, regulators and employers) want confidence that threshold learning standards in an accounting degree have been assured. Australia’s new higher education regulatory environment requires that student achievements are benchmarked against intended programme learning outcomes, guided by published disciplinary standards and a national qualifications framework, and against other higher education providers. Here, we report on a process involving academics from 10 universities, aided by professional practitioners, to establish and equip assessors to reliably assure threshold learning standards in accounting that are nationally comparable. Importantly, we are learning more about how standards are interpreted. Based on the premise that meaning is constructed from tacit experiences, social interactions and intentional reflection on explicit information, we report outcomes of three multi-part calibration interventions, situated around judgements of the quality of the written communication skills exhibited in student work and their related assessment tasks. Qualitative data from 30 participants in the calibration process suggest that they perceive that the process both assists them both in developing a shared understanding of the accounting threshold learning standards and in the redesign of assessment tasks to more validly assess the threshold learning standards. 相似文献

This article investigates the characteristics of KORMARC (Korean Machine Readable MARC) format and the role and influence of KORMARC on the development of library automation in Korea, as an example of library automation in the developing countries. The first section is a general overview of the development of KORMARC. In the second section, the characteristics of the KORMARC format for monographs are investigated, mainly based on the bibliographic characteristics in the East-Asian countries. In the third section, the influence of KORMARC on library automation in Korea is reviewed along with the prospects for the future. 相似文献

Applying the postulates and methodology of the universal value structure theory articulated by Schwarrs and Bilsky (1987, 1990) to mass communication, this study employs value type analysis to investigate how respondents' cultural background and television viewing habits are related to their perceptions of the importance of value types and to individualistic or collectivistic value structures. In this study, we found significant relations between television program genres viewed and individualist, collectivist, and mixed value types. The findings indicate that-throughout individualist, collectivist, and mixed value types-television program genre usually serves as a stronger predictor of value type importance than do demographic variables. 相似文献

Many media industries can be characterized as a closed content market in which only subscribers of the distribution network operator (Network Provider [NP]) have access to the content provided by a content provider (CP). In these markets, the NP frequently charges the CP for providing billing and connectivity services to potential customers. Due to this carriage payment, the closed content market has structural similarity to the coalitional form game. Consequently, concepts of superadditivity, the core, and the Shapley value can be applied to determine what constitutes a sustainable and fair share of the CP's profit that could be paid to the NP as a carriage payment. This article addresses issues concerning the existence of the sustainable and fair profit allocation in a closed content market like the one described previously. 相似文献

While a solid understanding of science content knowledge is important in developing expertise in science teaching, it is not necessarily a sufficient condition to teach science effectively in elementary schools. Teachers need to have the ability to transform their knowledge into forms learnable by students. Based on this perspective, the current study explored how science content knowledge was pedagogically transformed in Korean elementary classrooms. Data sources included video-recorded science lessons of five elementary teachers in a metropolitan city of Korea. The analysis of the data revealed that the Korean teachers often engaged in transforming science content knowledge by means of different semiotic modes, including language, pictures, materials, actions, and their complex combinations. Further, their representations of scientific knowledge were in diverse forms, such as personifications, analogies, quiz questions, pictorial models, diagrams, animations, real-life examples, hand demonstrations, videos, flash tools, and songs-and-dances. Future research involving a wider range of participants, such as students, content specialists, and teachers with weak and strong content understanding, was suggested to confirm the findings of this study and find more various ways of pedagogical transformation of science subject matter knowledge. 相似文献
