Two well-known lower bounds to the reliability in classical test theory, Guttman's 2 and Cronbach's coefficient alpha, are shown to be terms of an infinite series of lower bounds. All terms of this series are equal to the reliability if and only if the test is composed of items which are essentially tau-equivalent. Some practical examples, comparing the first 7 terms of the series, are offered. It appears that the second term (2) is generally worth-while computing as an improvement of the first term (alpha) whereas going beyond the second term is not worth the computational effort. Possibly an exception should be made for very short tests having widely spread absolute values of covariances between items. The relationship of the series and previous work on lower bound estimates for the reliability is briefly discussed.The authors are obliged to Henk Camstra for providing a computer program that was used in this study. 相似文献

The stimuli that control responding in the peak procedure were investigated by training rats, in separate sessions, to make two different responses for food reinforcement. During one type of session, lever pressing was normally reinforced 32 s after the onset of a light. During the other type of session, chain pulling was normally reinforced either 8 s after the onset of one auditory cue or 128 s after the onset of a different auditory cue. For both types of sessions, only the appropriate manipulandum was available, and 20% of the trials lasted 240 s and involved no response-contingent consequences. Rats were then tested with the auditory cues in the presence of the lever and the light in the presence of the chain. If the time of reinforcement associated with each stimulus was learned, response rates should peak at these times during transfer testing. However, if a specific response pattern was learned for each stimulus, little transfer should occur. The results did not clearly support either prediction, leading to the conclusion that both a representation of the time of reinforcement and the rat's own behavior may control responding in this situation. 相似文献

We demonstrate ways to incorporate nondeterminism in a system designed to formalize the reasoning of agents concerning their abilities and the results of the actions that they may perform. We distinguish between two kinds of nondeterministic choice operators: one that expresses an internal choice, in which the agent decides what action to take, and one that expresses an external choice, which cannot be influenced by the agent. The presence of abilities in our system is the reason why the usual approaches towards nondeterminism cannot be used here. The semantics that we define for nondeterministic actions is based on the idea that composite actions are unravelled in the strings of atomic actions and tests that constitute them. The main notions used in defining this semantics are finite computation sequences and finite computation runs of actions. The results that we obtain meet our intuitions regarding events and abilities in the presence of nondeterminism. 相似文献

This study tested factors related to collective action in East Asian and Western countries. Although the social identity model of collective action (SIMCA) could explain which factors relate to collective action in Western countries, previous studies have found that some of the SIMCA variables did not predict collective action in non‐Western countries. We hypothesised that the internal locus of control would be positively related to collective action even in East Asian countries because previous studies have demonstrated that the former can positively influence proactive behaviour when factors inhibiting such behaviours exist. We analysed the 2010 World Values Survey data from seven countries (three East Asian and four Western countries). The results demonstrated that the internal locus of control was positively related to collective action more so among East Asians (Koreans, specifically those with low political interests, the Taiwanese, and Japanese people with lower income) than among Westerners. These results suggest that the internal locus of control is a key individual difference that predicts collective action in the presence of factors that inhibit such participation (e.g., cultural values, low political interest, and low income). 相似文献

采用Stroop任务和前瞻记忆双任务实验范式,比较不同自我损耗条件对被试基于时间前瞻记忆(TBPM)的影响,及其对TBPM的加工阶段和成分的作用。然后通过添加外部时钟监控条件,探讨外部时钟是否可以减少自我损耗对TBPM的消极影响,以及自我损耗对时钟监控情况的作用。结果表明:(1)在内部控制条件下,自我损耗会严重影响TBPM的表现,高损耗组的TBPM成绩显著低于低损耗组,另外,自我损耗主要干扰前瞻记忆的前瞻成分和TBPM的第三个加工阶段。(2)在外部控制条件下,自我损耗没有降低TBPM的表现,说明外部时钟可以降低自我损耗对TBPM的消极影响。(3)自我损耗使个体呈现出不同的时钟监控模式,且邻近目标时间内的时钟监控次数与TBPM成绩呈显著正相关。 相似文献

While integrative and confrontational internal dialogues (IDs) are often treated as opposing and numerous positive functions are ascribed to the former, this paper assumes that integration and confrontation are not mutually exclusive but independent processes. When exploring IDs that simulate social relationships and are described by different configurations of integrative and confrontational characteristics, canonical correlation analysis revealed that in competitive dialogue, the strong confrontational attitude of the dialogue's author is accompanied by the weak integrative attitudes of both ID parties. The more the ID is based on a rivalry between the parties, the lower the levels of bond, support, and insight functions are and the higher the level of substitution is. In persuasive dialogue, the confrontational attitude of the dialogue's author is combined with the integrative attitudes of both parties. The more the ID is based on persuasion, the higher the intensity of substitution, insight, bond, support, and self-guiding is. The findings suggest a synergistic effect of co-occurring integrative and confrontational attitudes in one ID. 相似文献

“Internal relation” is a significant term in both Wittgenstein’s early and later philosophy. The term is used in relation to many problems, including our topic here, “aspect-seeing.” Some scholars have attempted to present a persuasive interpretation of this terminology; however, Wittgenstein’s remarks on “aspect-seeing” somehow thwart their approaches. The obstacle lies in the relata involved: Which terms are connected by an internal relation in the perception of an aspect? In this paper, I review the existing interpretations and present two proposals, one of which is conservative and the other slightly more radical. I argue that Wittgenstein makes divergent use of the distinction between “internal/external relations,” and that this may reveal the potential ambiguities of the words “internal” and “relation.” 相似文献

This study aims to bring to light the relationship between internal/external resources and counselors’ burnout depending on the type of clients (traumatized/bereaved vs. personal growth issues). Moderated mediation analysis was conducted with 165 counselors in South Korea. The results indicated that counselors of traumatized or bereaved clients were more likely to be affected by internal resources (countertransference management ability), whereas counselors of clients with personal growth issues were more likely to be affected by external resources (environmental resources). Implications and limitations of this study are discussed. 相似文献

分析比较切开复位内固定和人工桡骨小头置换方法治疗桡骨小头粉碎性骨折(MasonⅢ型)的临床疗效。回顾分析2012年10月~2014年3月收治的24例桡骨小头粉碎性骨折(MasonⅢ型)的临床资料,其中切开复位内固定治疗17例;桡骨小头置换7例,平均随访12个月(6个月~18个月)。根据Broberg Morrey评分系统以及术后影像进行评价比较,同时比较两组住院天数以及费用。结果评价比较显示两者疗效均佳,术后两者活动度和功能评分相近,两组住院天数相近,内固定组费用更低。桡骨小头粉碎性骨折须尽早进行解剖复住功能重建,切开复位内固定和桡骨小头置换疗效相当。 相似文献
