Teachers were asked to identify and rank 10 preferred stimuli for 9 toddlers, and a hierarchy of preference for these items was determined via a direct preference assessment. The reinforcing efficacy of the most highly preferred items identified by each method was evaluated concurrently in a reinforcer assessment. The reinforcer assessment showed that all stimuli identified as highly preferred via the direct preference assessment and teacher rankings functioned as reinforcers. The highest ranked stimuli in the direct assessment were more reinforcing than the teachers' top-ranked stimuli for 5 of 9 participants, whereas the teachers' top-ranked stimulus was more reinforcing than the highest ranked stimulus of the direct assessment for only 1 child. A strong positive correlation between rankings generated through the two assessments was identified for only 1 of the 9 participants. Despite poor correspondence between rankings generated through the teacher interview and direct preference assessment, results of the reinforcer assessment suggest that both methods are effective in identifying reinforcers for toddlers. 相似文献

National and religious identification processes can be seen as the basis of the conflict in Northern Ireland, and over the course of the conflict preferred social and political identities became increasingly oppositional and entrenched. This paper reviews this evidence using population-level studies of self-categorized national and religious identity. In an attempt to explore the bases of these identities, two interrelated qualitative studies examining the constructions of national and religious identification are reported. The findings presented suggest the continuing predominance of national and religious identities that have generally been constructed as opposing. Evidence of complete overlap of the identities is evidenced in conflation of religion and nationality in adolescents' essays. Theoretical sampling of adults living on the border between Northern Ireland, the republic of Ireland, and those in mixed marriages highlight the strategic use of national and religious identities that may act to support divisions in post-Agreement Northern Ireland. 相似文献

Five pigeons were trained on a procedure in which seven concurrent variable-interval schedules arranged seven different food-rate ratios in random sequence in each session. Each of these components lasted for 10 response-produced food deliveries, and components were separated by 10-s blackouts. We varied delays to food (signaled by blackout) between the two response alternatives in an experiment with three phases: In Phase 1, the delay on one alternative was 0 s, and the other was varied between 0 and 8 s; in Phase 2, both delays were equal and were varied from 0 to 4 s; in Phase 3, the two delays summed to 8 s, and each was varied from 1 to 7 s. The results showed that increasing delay affected local choice, measured by a pulse in preference, in the same way as decreasing magnitude, but we found also that increasing the delay at the other alternative increased local preference. This result casts doubt on the traditional view that a reinforcer strengthens a response depending only on the reinforcer's value discounted by any response-reinforcer delay. The results suggest that food guides, rather than strengthens, behavior. 相似文献

This paper is concerned with intransitivity in normative rational choice. It focuses on a class of intransitivities which
have received little attention, those involving vague preferences. “Vague preferences” are defined in terms of vague predicates
such as “red” or “bald.” Such preferences appear common, and intransitive indifference is argued to be an unavoidable feature
of them. Such preferences are argued to undermine intransitive strict preference also. Various formal theories of vagueness
are applied to an example of vague preferences, but none of them provide a justification for the transitivity axiom.

Several brief preference assessments have recently been developed to identify reinforcers for individuals with developmental disabilities. One purported advantage of brief assessments is that they can be administered frequently, thus accommodating shifts in preference and presumably enhancing reinforcement effects. In this study, we initially conducted lengthy paired‐choice preference assessments and identified a hierarchy of preferred items for 5 individuals with developmental disabilities. Subsequently, brief multiple‐stimulus‐without‐replacement assessments using the same items were completed each day prior to work sessions. On days when results of the daily brief assessment differed from the one‐time lengthy assessment, the relative reinforcing effects of the top items from each assessment were compared in a concurrent‐schedule arrangement. The results revealed that when the two assessments differed, participants generally allocated more responses to the task associated with the daily top‐ranked item. 相似文献

Effects of Attachment Style on Preferences for and Satisfaction with Different Employment Contracts: An Exploratory Study 总被引:1,自引:0,他引:1
Based on the characteristics of three attachment styles—secure, anxious/ambivalent, and avoidance—hypotheses were derived for differences between them with regard to preferences for three employment relationships differing in whether employees are internal—hired and paid by an organization or external—employed through software houses. In addition, hypotheses were also drawn for differences in overall and facet work satisfaction. The sample consisted of computer science students of whom a large proportion have also been working in that field, and individuals employed as software engineers. Anxious/ambivalents were relatively higher in preference for the external contract and lower in preference for the internal contract, as compared to the two other styles. Contrary to the hypotheses, the avoidants did not differ from the secure style in expressing the highest preference to the internal permanent contract and the lowest to the external contract. Work satisfaction was highest among the secure style but contrary to hypotheses, the anxious/ambivalent group did not differ significantly from that group concerning overall, intrinsic, and extrinsic satisfaction. The avoidants were lowest on those measures. Findings are discussed in light of the different attachment styles and the unique features of the high-tech industry. 相似文献

等待是一种折磨?等待时间知觉及其导致的非理性决策行为 总被引:2,自引:0,他引:2
等待时间知觉是指人们在等待过程中对等待时长的主观感受和心理体验, 它对人们的决策行为产生影响。影响等待时间知觉的客观因素包括等待过程的填充物、等待时间的确定性、接受服务的阶段和等待的物理环境等; 主观因素有负性情绪、自我控制和人格因素等。等待时间知觉导致的非理性决策行为包括时间沉没成本效应、“延迟-提前”框架效应、峰-终效应、偏好反转等。未来研究可从三个方面开展:(1) 时间启动和金钱启动下等待时间知觉的差异; (2) 基于时间心理账户视角研究等待时间知觉规律; (3) 借鉴时间知觉理论探讨等待(时间)影响决策行为的心理机制。 相似文献

研究以Ellsberg选瓶任务为决策材料,探讨了不同任务特征下个体不确定性容忍度对模糊决策中决策偏好的影响。结果发现,获益情景下:高概率时高、低容忍度个体对模糊选项的选择无显著差异,均偏好模糊规避;中概率时低容忍度个体比高容忍度个体表现出更低程度的模糊规避,前者倾向于模糊中立,后者倾向于模糊规避;低概率时两者对模糊选项的选择无显著差异,均倾向于模糊中立。损失情景下:高概率时两者对模糊选项的选择无显著差异,均倾向于模糊寻求;中概率时低容忍度比高容忍度个体更偏好模糊寻求,前者倾向于模糊寻求,后者倾向于模糊中立;低概率时两者对模糊选项的选择无显著差异,均倾向于模糊规避。这表明,不确定性容忍度对模糊决策偏好产生作用,但这种作用会受到损益概率和损益结果的影响,具有情景依赖性。 相似文献

The goal of this study is to report on the development of a measure designed to capture elderly satisfaction with local retail
establishments. The measure is based on the notion that elderly consumers experience well-being with retail institutions in
purchasing food, housing, household operations, household furnishings, clothing and accessories, personal care, medical care, recreation,
transportation, and education. Two-hundred and forty-nine (N = 249) elderly consumers were surveyed to demonstrate the validity of this measure. Specifically, it was hypothesized that
satisfaction with retail establishments in one’s community contributes to overall life satisfaction. The data supported the
validity of the measure. 相似文献
