This study examined interventions for addition and subtraction that were implemented through single-case design (SCD) research studies. We attempted to extend prior SCD meta-analyses by examining differences in effect sizes across several moderating variables and by including a novel index of effect, improvement rate difference (IRD). We also examined the extent to which effect sizes differed by degree of experimental control achieved in the studies. Forty-seven effect sizes were obtained across 11 studies. IRD effect sizes ranged from .59 to .90 and suggested a moderate to large effect for the math interventions. Variables that appeared to moderate the effects were student age, time spent in intervention, and intervention type. We also identified a relationship between experimental control and the obtained effect sizes. Findings indicated that further SCD research in basic arithmetic and rigorous experiments are necessary to establish an evidence base that accurately characterizes intervention effectiveness. 相似文献

In a recent editorial, Raymond Spier expresses skepticism over claims that climate change is driven by human actions and that humanity should act to avoid climate change. This paper responds to this skepticism as part of a broader review of the science and ethics of climate change. While much remains uncertain about the climate, research indicates that observed temperature increases are human-driven. Although opinions vary regarding what should be done, prominent arguments against action are based on dubious factual and ethical positions. Thus, the skepticisms in the recent editorial are unwarranted. This does not diminish the general merits of skeptical intellectual inquiry. 相似文献

ObjectivesThe purpose of this study was to examine the effects of different scoring protocols used with instruments designed to assess motivation in line with Organismic Integration Theory (OIT; Deci & Ryan, 2002).DesignThis study used non-probability based sampling within a cross-sectional (survey) design.MethodsParticipants across four samples (N's ranged from 236 to 1200) completed either (a) the Behavioral Regulation in Exercise Questionnaire (BREQ), (b) the BREQ-2, or (c) the BREQ-2R in conjunction with a self-report assessment of physical activity behavior.ResultsParticipants endorsed more self-determined than controlled motives for physical activity. Identified regulation was the dominant correlate of more frequent physical activity behavior. The link between external regulation and physical activity was consistently weak. Multiple regression analyses revealed identified regulation was the strongest predictor of physical activity compared with other motives. Regression models using omnibus scoring protocols accounted for less variance in physical activity behavior in contrast to an item-aggregation scoring protocol.ConclusionsIdentified regulation may be a key source of physical activity motivation in adults. The scoring protocol used with OIT-based instruments represents an important consideration for advancing physical activity research. 相似文献

Authenticity judgments involve how individuals distinguish what appears to be real versus fake, genuine versus phony. In this investigation, we bring authenticity into the laboratory to assess it in a manner quite different from most extant approaches. Taking a Peircian semiotic view in a context of environmentally conscious consumption, we develop and test a set of hypotheses concerning the effects of indexical and iconic cues to an authentic “green” product meaning. Results suggest that effects of these indicators of authenticity can be induced in a controlled manner with products being assessed as more or less “green” on the basis of particular cue arrangements. Furthermore, the effectiveness of these semiotic cues is moderated by a basic distinction among products. Taken together, the results provide evidence supporting a meaning validation process as the basis of authenticity judgments and suggest new directions for theory building in a domain where there is substantial practitioner interest.

The exhibition of actions that are causally unnecessary to the outcomes with which they are associated is a core feature of human cultural behavior. To enter into the world(s) of their cultural in-group, children must learn to assimilate such unnecessary actions into their own behavioral repertoire. Past research has established the habitual tendency of children to adopt the redundant actions of adults demonstrated directly to them. Here we document how young children will do so even when such actions are modeled to a third person regardless of whether children are presented with the test apparatus by the demonstrating, and assumedly expert, adult or by the observing, and assumedly naive, adult (Experiment 1), whether or not children had opportunity to discover how the apparatus works prior to modeling (Experiment 1), and whether or not children's attention was drawn to the demonstration while they were otherwise occupied (Experiment 2). These results emphasize human children's readiness to acquire behavior that is in keeping with what others do, regardless of the apparent efficiency of the actions employed, and in so doing to participate in cultural learning. 相似文献

Does inferential justification require the subject to be aware that her premises support her conclusion? Externalists tend to answer “no” and internalists tend to answer “yes”. In fact, internalists often hold the strong higher-level requirement that an argument justifies its conclusion only if the subject justifiably believes that her premises support her conclusion. I argue for a middle ground. Against most externalists, I argue that inferential justification requires that one be aware that her premises support her conclusion. Against many internalists, I argue that this higher-level awareness needn’t be doxastic or justified. I also argue that the required higher-level awareness needn’t be caused in some appropriate way, e.g. by a reliable or properly functioning faculty. I suspect that this weaker higher-level requirement is overlooked because, at first glance, it seems absurd to allow nondoxastic, unjustified, and unreliably-caused higher-level awareness to contribute to inferential justification. One of the central goals of this paper is to explain how such weak awareness can make an essential contribution to inferential justification. 相似文献

This study examined the proportion of people who held ambivalent versus univalent sexist attitudes, that is, those who simultaneously endorsed benevolent sexism (BS) and hostile sexism (HS). We examined this by capitalizing on recent innovations in latent class analysis to model latent types of sexists, or response profiles to BS and HS, in a nationally representative New Zealand sample (n = 6450). Our results show, for the first time, that by far, the most common pattern was for people to hold similar levels of BS and HS. Strongly ambivalent sexists, however, constituted only 8%–9% of the population. Most were classified as mild or moderate ambivalent sexists (28% and 44%, respectively). Univalent sexism was exceedingly rare, with between 2% and 5% of people solely endorsing HS but not BS, or BS but not HS. We validated the model by showing theoretically predicted differences across sexist types in demographics (gender, age), ideology (social dominance orientation, right‐wing authoritarianism), and relationship satisfaction. Strongly ambivalent sexists also held the highest levels of gender‐specific system justification, invariant of gender. This provides novel evidence for the premise that strong sexist ambivalence promotes support for and faith in the patriarchical system. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

The purpose of the present study was to highlight the role of location-identity binding mismatches in obscuring explicit awareness of a strong contingency. In a spatial-priming procedure, we introduced a high likelihood of location-repeat trials. Experiments 1, 2a, and 2b demonstrated that participants' explicit awareness of this contingency was heavily influenced by the local match in location-identity bindings. In Experiment 3, we sought to determine why location-identity binding mismatches produce such low levels of contingency awareness. Our results suggest that binding mismatches can interfere substantially with visual-memory performance. We attribute the low levels of contingency awareness to participants' inability to remember the critical location-identity binding in the prime on a trial-to-trial basis. These results imply a close interplay between object files and visual working memory. 相似文献

We synthesized and meta-analyzed 73 studies (N = 71,895) examining the associations between Big-Five personality and single-item self-placement measures of political orientation. Openness to Experience (r = −.18) and Conscientiousness (r = .10) were significantly but weakly correlated with political conservatism. The weak Openness-political orientation link was moderated by systemic threat and uncertainty (indexed by nation-wide homicide and unemployment). We propose a Threat-Constraint Model explaining this previously undetected Person × Situation interaction. The model shows that there was a moderately-sized negative correlation between Openness and political conservatism when systemic threat was low (r = −.422) but that this association was negligible at only moderate levels of threat (r = −.066). These findings highlight the economic and societal constraints of personality-political ideology associations. 相似文献
