Four experiments with preschool-aged children test the hypothesis that engaging in explanation promotes inductive reasoning on the basis of shared causal properties as opposed to salient (but superficial) perceptual properties. In Experiments 1a and 1b, 3- to 5-year-old children prompted to explain during a causal learning task were more likely to override a tendency to generalize according to perceptual similarity and instead extend an internal feature to an object that shared a causal property. Experiment 2 replicated this effect of explanation in a case of label extension (i.e., categorization). Experiment 3 demonstrated that explanation improves memory for clusters of causally relevant (non-perceptual) features, but impairs memory for superficial (perceptual) features, providing evidence that effects of explanation are selective in scope and apply to memory as well as inference. In sum, our data support the proposal that engaging in explanation influences children’s reasoning by privileging inductively rich, causal properties. 相似文献

With Internet access no longer restricted to desktop and laptop computers, job applicants now have the opportunity to complete remotely delivered assessments on mobile, handheld small screen devices such as smartphones, and personal digital assistants. In this study, a large dataset is used to investigate demographic and score differences between job applicants who completed a remotely delivered high‐stakes assessment on a mobile device and those who completed it on a nonmobile device. Based on a sample of 3,575,207 job applicants who completed an unproctored Internet‐based assessment between January 2011 and April 2012, the percentage of applicants completing the assessment on a mobile device was small, 1.93%, but nevertheless represented more than 69,000 people. Overall, there were small test‐taker demographic differences in the use of mobile devices versus nonmobile devices in that mobile devices were slightly more likely to be used by women, African‐Americans and Hispanics, and younger applicants. Scores on a personality measure were similar for mobile and nonmobile devices but scores on a general mental ability test were substantially lower for mobile devices. Tests of measurement invariance also indicated equivalence across the mobile and nonmobile samples. Test taker and organizational implications for completing remotely delivered high‐stakes noncognitive and cognitive assessments on mobile versus nonmobile devices are discussed. 相似文献

We determined how various cognitive abilities, including several measures of a proposed domain‐specific number sense, relate to mathematical competence in nearly 100 9‐year‐old children with normal reading skill. Results are consistent with an extended number processing network and suggest that important processing nodes of this network are phonological processing, verbal knowledge, visuo‐spatial short‐term and working memory, spatial ability and general executive functioning. The model was highly specific to predicting arithmetic performance. There were no strong relations between mathematical achievement and verbal short‐term and working memory, sustained attention, response inhibition, finger knowledge and symbolic number comparison performance. Non‐verbal intelligence measures were also non‐significant predictors when added to our model. Number sense variables were non‐significant predictors in the model and they were also non‐significant predictors when entered into regression analysis with only a single visuo‐spatial WM measure. Number sense variables were predicted by sustained attention. Results support a network theory of mathematical competence in primary school children and falsify the importance of a proposed modular ‘number sense’. We suggest an ‘executive memory function centric’ model of mathematical processing. Mapping a complex processing network requires that studies consider the complex predictor space of mathematics rather than just focusing on a single or a few explanatory factors. 相似文献

International carrier testing guidelines discourage testing in childhood to preserve autonomous decision making and prevent detrimental psychosocial consequences. Despite the discouragement of autosomal recessive carrier testing during childhood, some sickle cell disease (SCD) or cystic fibrosis (CF) carriers are incidentally identified through UK and international newborn screening (NBS). This creates a scenario where parents may have knowledge of their newborn’s, but not older child’s carrier status. In addition, there is wide variation in the identification of CF and SCD carriers due to the screening technologies implemented by different NBS programs. The current and future availability of childhood testing are determined to some extent by the impact of testing on children and parents (whether this is beneficial or detrimental to wellbeing). However empirical research informing carrier guidance and practice is conflicting. Echoing previous calls, this discussion highlights the need for further qualitative and longitudinal research with children to consider the psychosocial impact of carrier testing on children and role of disclosure from parents on adaptation to results. It is recommended that professionals aim to minimize harms resulting from carrier identification by providing support for parents and children following NBS. Support for non-genetics specialists from genetic counselors to enable discussion of carrier results with children is suggested. 相似文献

We examined the components and situational correlates of state authenticity to clarify the construct's meaning and improve understanding of authenticity's attainment. In Study 1, we used the day reconstruction method (participants assessed real‐life episodes from ‘yesterday’) and in Study 2 a smartphone app (participants assessed real‐life moments taking place ‘just now’) to obtain situation‐level ratings of participants' sense of living authentically, self‐alienation, acceptance of external influence, mood, anxiety, energy, ideal‐self overlap, self‐consciousness, self‐esteem, flow, needs satisfaction, and motivation to be ‘real’. Both studies demonstrated that state authentic living does not require rejecting external influence and, further, accepting external influence is not necessarily associated with state self‐alienation. In fact, situational acceptance of external influence was more often related to an increased, rather than decreased, sense of authenticity. Both studies also found state authentic living to be associated with greater, and state self‐alienation with lesser: positive mood, energy, relaxation, ideal‐self overlap, self‐esteem, flow, and motivation for realness. Study 2 further revealed that situations prioritizing satisfaction of meaning/purpose in life were associated with increased authentic living and situations prioritizing pleasure/interest satisfaction were associated with decreased self‐alienation. State authenticity is best characterized by two related yet independent components: authentic living and (absence of) self‐alienation.

Does imagery reduce stigma against depression? Testing the efficacy of imagined contact and perspective‐taking 下载免费PDF全文
While the stigma surrounding mental illness has been well‐established, less is known about methods for reducing that bias. In both laboratory (Study 1) and community (Study 2) samples, we tested the efficacy of imagined contact and perspective‐taking for reducing stigma against depression. Participants first read a vignette about an individual with depression and then imagined either interacting with the individual (imagined contact), putting themselves in the individual's shoes (perspective‐taking) or a neutral scene (control). In both samples, imagined contact was more effective in reducing stigma against depression than perspective‐taking. The findings suggest that different prejudice reduction strategies should be used for different stigmatized groups. 相似文献

Using both quantitative and qualitative data, this study examined the effect of participating in an action civics intervention, Generation Citizen (GC), on civic commitment, civic self‐efficacy, and two forms of civic knowledge. The sample consisted of 617 middle and high schools students in 55 classrooms who participated, or were soon to participate, in Generation Citizen. Hierarchical linear models revealed that participating in Generation Citizen was associated with positive gains in action civics knowledge and civic self‐efficacy. Qualitative coding identified three types of project characteristics that captured variability in the action projects student chose to complete: context, content, and contact with decision makers. Interactions between project characteristics and participation in GC revealed differences in civic outcomes depending on project characteristics. 相似文献
