Reviewers of research are more lenient when evaluating studies on important topics [Wilson, T. D., Depaulo, B. M., Mook, D. G., & Klaaren, K. J. (1993). Scientists’ evaluations of research: the biasing effects of the importance of the topic. Psychological Science, 4(5), 323-325]. Three experiments (N = 145, 36, and 91 psychologists) investigated different explanations of leniency, including inflation of assessments (applying a heuristic associating importance with quality), oversight (failing to detect flaws), and error-weighting (prioritizing Type II error avoidance). In Experiment 1, psychologists evaluated the publishability and rigor of studies in a 2 (topic importance) × 2 (accuracy motivation) × 2 (research domain) design. Experiment 2 featured an exact replication of Wilson et al. and suggested that report length moderated the effects of importance on perceived rigor, but not on publishability. In Experiment 3, a manipulation of error-weighting replaced the manipulation of domain (Experiment 1). Results favored error-weighting, rather than inflation or oversight. Perceived seriousness of Type II error (in Experiments 1 and 3) and the error-weighting manipulation (in Experiment 3) predicted study evaluations.  相似文献

Zentall and Singer (2007) challenge our conclusion that the work-ethic effect reported by Clement, Feltus, Kaiser, and Zentall (2000) may have been a Type I error by arguing that (a) the effect has been extensively replicated and (b) the amount of overtraining our pigeons received may not have been sufficient to produce it. We believe that our conclusion is warranted because (a) the original effect has not been replicated despite multiple attempts to do so and (b) the statement that more extended overtraining may be needed itself suggests that the original effect is not reliable.  相似文献

The current study analysed crashes identified in a large-scale naturalistic driving database to assess the prevalence of cognitive disengagement (i.e., purely cognitive distraction and mind wandering/microsleep) or episodes wherein the driver did not look away from the roadway during secondary task completion or wherein another clearly observable contributing crash factor was not present, and the driver's reaction to the crash showed symptoms of cognitive disengagement. The study found that <1% (95% CI [0.45, 1.66]) of higher severity crashes had a potential contributing crash factor of mind wandering/microsleep; ~1.5% (95% CI [0.83, 2.32]) had a potential contributing factor of purely cognitive distraction. The results suggest a relatively low prevalence of cognitive disengagement among automotive crashes compared with visual/manual secondary tasks. However, the current methodology is limited in that it does not account for instances where cognitive disengagement, in combination with other factors, may have led to crashes, potentially leading to conservative estimates.  相似文献

电子商务以互联网为依托,并随着互联网的广泛应用而迅速发展。电子商务中的消费者合同因其特殊性,正挑战传统的管辖权理论。在电子商务管辖权确定的原则方面,目前还没有一种为各国所普遍接受的标准,这使得电子商务管辖权问题仍然处在探索阶段。本文主要分析电子商务背景下的消费者电子合同的特点以及对传统管辖权制度造成的冲击,介绍相关国际组织在调整网络条件下的消费者合同管辖权方面的经验,并针对中国的实际情况,对完善我国消费者电子合同管辖权制度提出几点建议。  相似文献

Many of the errors that occur in children' subtraction are due to the use of incorrect strategies rather than to the incorrect recall of number facts. A production system is presented for performing written subtraction which is consistent with an earlier analysis of the nature of such a cognitive skill. Most of the incorrect strategies used by schoolchildren can be accounted for in a principled way by simple changes in the production system, such as the omission of individual rules or the inclusion of rules appropriate to other arithmetical tasks. The production system model is evaluated against a corpus of over 1500 subtraction problems done by 10-year olds and is shown to account for about two-thirds of the (nonnumber fact) errors. It also provides an alternative, simpler interpretation of the subtraction errors analysed by Brown and Burton (1978). Some implications for teaching are discussed.  相似文献

回顾性分析乳腺浸润性微乳头状癌(IMPC)的临床病理特征.选取河北医科大学第四医院乳腺中心手术切除并经病理证实的女性原发性乳腺癌共3 383例,筛选出符合IMPC为实验组,同期乳腺浸润性导管癌(IDC)为对照组.结果显示,本组IMPC 167例,占同期乳腺癌4.94%,年龄29岁~80岁,中位年龄54岁.淋巴结转移者共135例,占80.8%,淋巴结转移数目≥4个共105例,占62.9%,HER2阳性率58.7%,与IDC组相比差异均有统计学意义(P<0.05).IMPC为一种少见类型的浸润性乳腺癌,具有淋巴管侵袭性强、淋巴结转移率高的生物学行为.应与其他类型肿瘤进行鉴别,明确诊断.  相似文献

The concurrent, criterion-related and discriminant validity of four of the MMPI-2 content scales were examined within a population of 309 patients being evaluated for the treatment of chronic pain. Utilizing both self-report and therapist-derived criteria, the MMPI-2 content scales designed to assess symptoms of anxiety (ANX), depression (DEP), low self-esteem (LSE), and anger (ANG) demonstrated the ability to provide valid information beyond that provided by the traditional MMPI-2 clinical and validity indices. Further, a multi-trait/multi-method analytic approach revealed; (1) strong discriminant validity for the ANG content scale and (2) substantial variance overlap among all the self-report measures of subjective distress, compromising our efforts to evaluate the discriminant validity of the ANX, DEP, and LSE content scales.  相似文献

A community sample of foreign-born first generation (n = 53) and U.S.-born secondgeneration (n = 57) youth of Indian origin (ages 18–25) was studied. Variables predicting self-critical perfectionism were perceived prejudice, enculturation, and communication difficulty with parents and their interaction with generation status. The differences between the two generations pointed to nuanced self-pressures of Indian immigrant youth, despite good academic standing and middle-class family income. Implications discuss counseling with Indian immigrant youth.  相似文献

Although the number of studies on online reviews is growing, the impact of reviewer photo on consumer purchase decision-making has not yet been examined systematically. In particular, the underlying neural mechanisms have remained underexplored. Thus, the present study investigated whether and how reviewer photos affects consumers to make a purchase decision by using eventrelated potentials (ERPs). At the behavioral level, participants demonstrated a higher purchase rate with a shorter RT in situations with reviewer photos compared to situations without reviewer photos. Meanwhile, at the neural level, compared with situations without reviewer photos, situations with reviewer photos attracted more rapid attention resources at the early automatic processing phase, which induced a greater P2 amplitude, then mobilized more sustained attention allocation at the cognitive monitoring phase due to its evolutionary significance which elicited a more negative N2 amplitude, and finally resulted in a better evaluative categorization with higher motivational and emotional arousal due to its social presence which evoked a larger late positive potential (LPP) amplitude at the late elaborate cognitive processing phase. Those results illuminated the neural pathway of purchase decision-making when consumers were exposed in different conditions of reviewer photo. Moreover, the current study provided evidence for the underlying influence of reviewer photo on purchase decision-making in online shopping.  相似文献
