Situational judgment tests (SJTs) have become popular selection methods, with 59 empirical studies having been published since 1990. In contrast to prior narrative reviews or meta-analyses, this study develops (a) a comprehensive structure of SJT features, or “attributes,” (b) uses this structure to quantitatively and qualitatively summarize existing research in a content analysis, and then (c) uses the content analysis to generate directions for future research. The review is organized around a single question: What are the current practices in SJT research? Using this question as a foundation, we focus the content analysis on three significant theoretical and practical themes: (a) SJT development, scoring methods, and uses; (2) types of reliability estimates reported for SJTs, and (3) attributes that enhance or reduce internal consistency reliability.  相似文献

Hardly any region has recently captured the global geopolitical imagination as much as the Arab world after the so-called Arab Spring and very likely no state more so than Egypt. Finally it seemed that democracy was coming to the region, that this would spell the end of radical Islam, and of any local aspirations of creating Islamic states, and mark the beginning of a rapprochement between East and West. This article analyses and links those dynamics, with particular reference to the transition process in the wake of the so-called Arab Revolution, and gauges what may be at stake for members of non-Muslim faiths. It particularly traces the rift between theoretical Muslim discourse about Islamic tolerance towards other faiths and its implementation or the absence thereof in practice. It concludes that so far no real progress has been made and that, for the relationship to evolve, Islam needs to proceed to a state in which it sees itself as no more than an equal to other religions. The recognition of its tradition-based nature and of the consequences that flow from such a realization for the treatment of its fundamental sources, the Qur'an and the Sunna, will be addressed. To evaluate the current situation and the outlook, we shall use the example of the famous eighteenth-century German play by Gotthold Ephraim Lessing, Nathan the Wise, about the occupation of Jerusalem by Saladin.  相似文献

This paper explores several paths by which the extended cognition (EC) thesis may overcome the coupling-constitution fallacy. In so doing, I address a couple of shortcomings in the contemporary literature. First, on the dimension of first-wave EC, I argue that constitutive arguments based on functional parity suffer from either a threat of cognitive bloat or an impasse with respect to determining the correct level of grain in the attribution of causal-functional roles. Second, on the dimension of second-wave EC, I argue that especially the complementarity approach suffers from a similar sort of dilemma as first-wave EC: an inability to justify just what entails the ontological claim of EC over the scaffolding claim of weaker approaches in cognitive science. In this paper I show that two much more promising explanations by which to ground the ontological claim of EC are available, both starting from an exploration of the coordination dynamics between environmental resources and neural resources. On the one hand, I argue that second-wave EC based on cognitive integration, with its focus on bodily manipulations constrained by cognitive norms, is capable of resolving the coupling-constitution fallacy. On the other hand, I argue that the framework of cognitive integration can be supplemented by philosophical accounts of mechanistic explanation, because such accounts enable us to explain the emergence of higher-level cognitive properties due to a system's organization-dependent structure.  相似文献

Recent studies have established that even infants can determine what others know based on previous visual experience. In the current study, we investigated whether 2- and 3-year-olds know what others know based on previous auditory experience. A child and an adult heard the sound of one object together, but only the child heard the sound of another (target) object. When later the sounds of both objects were played simultaneously, the adult reacted with surprise and excitement (“Oh, listen, what is that?”). In response, both 24- and 36-month-olds directed the adult's attention to the target more often than chance and more often than in a control condition in which the adult had heard neither sound. These results indicate that by 24 months of age, children's understanding of others' knowledge and ignorance is not limited to the visual domain but extends across perceptual domains.  相似文献

Patients with schizophrenia (SZ) show cognitive impairments on a wide range of tasks, with clear deficiencies in tasks reliant on prefrontal cortex function and less consistently observed impairments in tasks recruiting the striatum. This study leverages tasks hypothesized to differentially recruit these neural structures to assess relative deficiencies of each. Forty-eight patients and 38 controls completed two reinforcement learning tasks hypothesized to interrogate prefrontal and striatal functions and their interaction. In each task, participants learned reward discriminations by trial and error and were tested on novel stimulus combinations to assess learned values. In the task putatively assessing fronto-striatal interaction, participants were (inaccurately) instructed that one of the stimuli was valuable. Consistent with prior reports and a model of confirmation bias, this manipulation resulted in overvaluation of the instructed stimulus after its true value had been experienced. Patients showed less susceptibility to this confirmation bias effect than did controls. In the choice bias task hypothesized to more purely assess striatal function, biases in endogenously and exogenously chosen actions were assessed. No group differences were observed. In the subset of participants who showed learning in both tasks, larger group differences were observed in the confirmation bias task than in the choice bias task. In the confirmation bias task, patients also showed impairment in the task conditions with no prior instruction. This deficit was most readily observed on the most deterministic discriminations. Taken together, these results suggest impairments in fronto-striatal interaction in SZ, rather than in striatal function per se.  相似文献

In light of the World Anti Doping Agency’s 2013 Code Revision process, we critically explore the applicability of two of three criteria used to determine whether a method or substance should be considered for their Prohibited List, namely its (potential) performance enhancing effects and its (potential) risk to the health of the athlete. To do so, we compare two communities of human guinea pigs: (i) individuals who make a living out of serial participation in Phase 1 pharmacology trials; and (ii) elite athletes who engage in what is effectively ‘unregulated clinical research’ by using untested prohibited or non-prohibited performance enhancing substances and methods, alone or in combination. Our comparison sheds light on norms of research ethics that these practices exacerbate with respect to the concepts of multiplicity, visibility, and consistency. We argue for the need to establish a proper governance framework to increase the accountability of these unregulated research practices in order to protect the human guinea pigs in elite sports contexts, and to establish reasonable grounds for the performance enhancing effects, and the risks to the health of the athlete, of the methods and substances that might justify their inclusion on the Prohibited List.  相似文献

In the early parts of the 20th century, character made up a major part of psychology, specifically of personality psychology. However, an influential observational study of children's moral behavior, conducted by Hartshorne, May, and colleagues in the 1920s, suggested that consistency in morality‐related behavior was lower than many people expected. Some psychologists interpreted such results to mean that there was no consistency in moral behavior and thus that there were no stable, meaningful individual differences in moral behavior – character did not exist. Recent years have witnessed a reinvigoration of character, ethics, and morality as objects of psychological study. Our purpose in this paper is to contribute to this reinvigoration by reviewing the use of the concept of “character” within psychology, considering whether the evidence supports the notion of moral character as a psychological construct, and suggesting new prospects for research on moral character.  相似文献

Although the biases and anomalies characterizing psychometric data should serve as conclusive evidence of systematic flaws in scientific methodology, these problems are usually ignored, which reduces empirical psychology to the closed system of its error theory. However, psychometric scores are ambiguous, and response-shifts and fluctuating validities point to fundamental differences in what the measuring-apparatus questionnaire records and how the measuring-apparatus person judges. Therefore, empirical methods fail when psychology requires evidence-based knowledge about cognitive processes and phenomena. Correcting these flaws requires a reassessment of basic scientific premises and careful consideration of Homo sapiens’ biosemiotic heuristics. Based on comprehensive biopsychosocial, data, the author reconstructs the evolutionary axioms of self-referenced cognitions and reveals what is usually obscured by the axioms of normal science. He substantiates the need for a paradigm shift toward basic bio–cultural principles and an evolutionary understanding of human thinking and behavior.  相似文献

Three experiments are reported that collectively show that listeners perceive speech sounds as contrasting auditorily with neighboring sounds. Experiment 1 replicates the well-established finding that listeners categorize more of a [d–g] continuum as [g] after [l] than after [r]. Experiments 2 and 3 show that listeners discriminate stimuli in which the energy concentrations differ in frequency between the spectra of neighboring sounds better than those in which they do not differ. In Experiment 2, [alga–arda] pairs, in which the energy concentrations in the liquid-stop sequences are H(igh) L(ow)–LH, were more discriminable than [alda–arga] pairs, in which they are HH–LL. In Experiment 3, [da] and [ga] syllables were more easily discriminated when they were preceded by lower and higher pure tones, respectively—that is, tones that differed from the stops’ higher and lower F3 onset frequencies—than when they were preceded by H and L pure tones with similar frequencies. These discrimination results show that contrast with the target’s context exaggerates its perceived value when energy concentrations differ in frequency between the target’s spectrum and its context’s spectrum. Because contrast with its context does more that merely shift the criterion for categorizing the target, it cannot be produced by neural adaptation. The finding that nonspeech contexts exaggerate the perceived values of speech targets also rules out compensation for coarticulation by showing that their values depend on the proximal auditory qualities evoked by the stimuli’s acoustic properties, rather than the distal articulatory gestures.  相似文献
