Personal response systems, commonly called ‘clickers’, are widely used in secondary and post‐secondary classrooms. Although many studies show they enhance learning, experimental findings are mixed, and methodological issues limit their conclusions. Moreover, prior work has not determined whether clickers affect cognitive change or simply alert students to information likely to be on tests. The present investigation used a highly controlled methodology that removed subject and item differences from the data to explore the effect of clicker questions on memory for targeted facts in a live classroom and to gain a window on the cognitive processes affecting the outcome. We found that in‐class clicker questions given in a university psychology class augmented performance on delayed exam questions by 10–13%. Experimental results and a class survey indicate that it is unlikely that the observed effects can be attributed solely to attention grabbing. Rather, the data suggest the technology invokes the testing effect. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

The current study examined the extent to which an expanded self-punitiveness model could be applied to deliberate self-harm
(DSH) among students making the transition to university. Specific components of the self-punitiveness model included perfectionism,
overgeneralization, self-criticism, and shame. A sample of 319 university students completed a measure of deliberate self-harm
as well as two multidimensional perfectionism measures and measures of self-criticism, overgeneralization, and shame. Correlational
analyses found few significant associations among deliberate self-harm and the self-punitiveness factors among men. In contrast,
among women, deliberate self-harm was associated with dimensions of trait perfectionism such as parental criticism and socially
prescribed perfectionism, as well as with overgeneralization, self-criticism, and both characterological shame and bodily
shame with the strongest associations found with shame. Supplementary analyses found a strong link between overgeneralization
and shame and an association between self-criticism and shame among women. The results support the contention that particularly
among young women making the transition to university, deliberate self-harm behavior is a reflection of a self-punitive personality
orientation with multiple facets and a sense of shame associated with an overgeneralized sense of failing to meet social expectations. 相似文献

ObjectivesThis study examined youth ice hockey players' perceptions of individual feedback received from their coach, and the agreement and discrepancies between preferred and perceived coach feedback patterns, on athletes' perceptions of team motivational climate. The following research questions were answered: How does agreement in perceived and preferred coach feedback relate to task- and ego-involving motivational climate? How does the degree of discrepancy between perceived and preferred coach feedback relate to motivational climate? How does the direction of the discrepancy between perceived and preferred coach feedback relate to motivational climate?DesignThis study used non-probability based sampling within a cross-sectional (survey) design.MethodAthletes (n = 70) completed a self-report survey comprised of measures of coaching feedback and motivational climate. The data were examined using polynomial regression and response surface analysis.ResultsLinear associations were observed between coaching feedback and motivational climate, and unique associations between the perceived and preferred coach feedback discrepancies were distinctly related to increased perceptions of both task- and ego-involved motivational climates.ConclusionsThe type of feedback, purpose of the feedback, and agreement or discrepancy in perceptions and preferences for different feedback styles are important to understanding task- and ego-involved motivational climate in youth sport. Coaching programs should assist coaches in learning their athletes' preferences for positive and negative feedback in sport and matching these preferences with their individual feedback styles. 相似文献

This multimethod series of studies merges the literatures on gratitude and risk regulation to test a new process model of gratitude and relationship maintenance. We develop a measure of appreciation in relationships and use cross-sectional, daily experience, observational, and longitudinal methods to test our model. Across studies, we show that people who feel more appreciated by their romantic partners report being more appreciative of their partners. In turn, people who are more appreciative of their partners report being more responsive to their partners' needs (Study 1), and are more committed and more likely to remain in their relationships over time (Study 2). Appreciative partners are also rated by outside observers as relatively more responsive and committed during dyadic interactions in the laboratory, and these behavioral displays are one way in which appreciation is transmitted from one partner to the other (Study 3). These findings provide evidence that gratitude is important for the successful maintenance of intimate bonds. 相似文献

The base units of the SI include six units of continuous quantities and the mole, which is defined as proportional to the number of specified elementary entities in a sample. The existence of the mole as a unit has prompted comment in Metrologia that units of all enumerable entities should be defined though not listed as base units. In a similar vein, the BIPM defines numbers of entities as quantities of dimension one, although without admitting these entities as base units. However, there is a basic ontological distinction between continuous quantities and enumerable aggregates. The distinction is the basis of the difference between real and natural numbers. This paper clarifies the nature of the distinction: (i) in terms of a set of measurement axioms stated by H?lder; and (ii) using the formalism known in metrology as quantity calculus. We argue that a clear and unambiguous scientific distinction should be made between measurement and enumeration. We examine confusion in metrological definitions and nomenclature concerning this distinction, and discuss the implications of this distinction for ontology and epistemology in all scientific disciplines. 相似文献

The misinformation effect is a well-established phenomenon in the false memory literature, although the mechanisms that underlie it are debated. In the present study, we explored one aspect of the controversy, the fate of the original memory. We began from an activation-based view of memory, capitalizing on the well-understood processes of associative priming and spreading activation, to test the hypothesis that true and suggested information can coexist in memory. After exposure to misinformation, participants were unknowingly primed with associates of either the true or a suggested item. Misled participants who were primed for the true item performed better on a final memory test than did misled participants primed for neutral information. The results indicated that true and suggested information coexist and that retrieval is influenced by each concept's activation level at test. Implications for theories of the misinformation effect were discussed. 相似文献

The role of interpersonal components of perfectionism in suicide outcomes among youth was assessed and the Perfectionism Social Disconnection Model (PSDM) was tested by determining whether the links between socially prescribed perfectionism (SPP) and perfectionistic self-presentation (PSP) and suicide outcomes are mediated by experiences of social disconnection, as indicated by social hopelessness and being bullied. PSP, trait perfectionism, suicide outcomes, and experiences of being bullied and social hopelessness were measured in 152 psychiatric outpatient children and adolescents. Correlational tests confirmed that PSP and SPP were associated with suicide outcomes and these interpersonal perfectionism components were associated significantly with bullying and social hopelessness. Support was also obtained for the PSDM. The relationship between the PSP facets, particularly nondisplay of imperfections, and suicide outcomes were mediated by being bullied. Additionally, the relationship between all interpersonal components of perfectionism and suicide risk was mediated by social hopelessness. Theoretical and clinical implications of interpersonal components of perfectionism and social disconnection in suicide outcomes for youth are discussed. 相似文献
