Little is known about the mechanisms underlying a ubiquitous behavior in preschoolers, help‐seeking. We tested the hypothesis that preschoolers' awareness of their own uncertainty is associated with help‐seeking. Three‐, 4‐, and 5‐year‐olds (N = 125) completed a perceptual identification task twice: once independently and once when they could request help from a confederate whose competence level was manipulated. Consistent with our hypothesis, participants sought help more frequently on trials for which, when required to answer independently, they expressed lower confidence. Children in the bad‐helper condition were slower to respond after receiving help than those in the good‐helper condition. Finally, females and children with more advanced theory of mind were more likely to seek help, identifying additional factors that relate to help‐seeking.  相似文献

Most studies of ideal-body media effects on body image focus on the extreme thinness of the models, not their idealness. In modern media, this idealness is often created or maximized via digital image editing. This experiment tested the effects of image editing outside the research-typical context of exclusive thinness. Original unretouched photographs were manipulated by a professional retoucher to produce unretouched and retouched image conditions. In a third condition (retouched-aware), the retouched images were explicitly labeled as retouched. Adolescents ( N = 393, average age 15.43) were randomly assigned to one of these conditions or a no-exposure control, and they completed a questionnaire following exposure. Objectified body consciousness increased and physical self-esteem decreased among male and female adolescents in the retouched-aware condition only. This boomerang effect of retouching awareness is explored in the discussion.  相似文献

In a series of two experiments, we examined 5-year-old children's motivations for learning new conventional actions. Children watched two teachers open a novel container; the teachers differed in the nonfunctional, conventional actions they used in the process. In Experiment 1, one teacher spoke with a native accent and the other spoke with a nonnative accent. Children showed a preference for following the native-accented teacher, and this preference was interpreted as a motivation to match an in-group member. In Experiment 2, the speech accent of the teacher was crossed with explicit expressions of (un)certainty by the teachers. In this case, children preferred the more certain teacher, even when the certain teacher spoke with a nonnative speech accent. This preference was taken as demonstrating a utilitarian motivation that led to choosing the teacher most likely to have useful information. Taken together, these results suggest that by 5 years of age, children are motivated by both utilitarian and in-group considerations when selecting between sources of information; however, when forced to select between the two motivations, utilitarian concerns take precedent.  相似文献

Cancer genetics professionals face a new opportunity and challenge in adapting to the availability of cancer genetic testing panels, now available as a result of Next Generation Sequencing (NGS) technology. While cancer panels have been available for over a year, we believe that there is not yet enough data to create practice guidelines. Despite this, a year of experience allows us to provide our opinion on points to consider as cancer genetic counselors incorporate this testing technology into genetic counseling practice models. NGS technology offers the ability to potentially diagnose hereditary cancer syndromes more efficiently by testing many genes at once for a fraction of what it would cost to test each gene individually. However, there are limitations and additional risks to consider with these tests. Obtaining informed consent for concurrent testing of multiple genes requires that genetics professionals modify their discussions with patients regarding the potential cancer risks and the associated implications to medical management. We propose dividing the genes on each panel into categories that vary by degree of cancer risk (e.g. penetrance of the syndrome) and availability of management guidelines, with the aim to improve patient understanding of the range of information that can come from this testing. The increased risk for identifying variants of uncertain significance (VUS) when testing many genes at once must be discussed with patients. Pretest genetic counseling must also include the possibility to receive unexpected results as well as the potential to receive a result in the absence of related medical management guidelines. It is also important to consider whether a single gene test remains the best testing option for some patients. As panels expand, it is important that documentation reflects exactly which genes have been analyzed for each patient. While this technology holds the promise of more efficient diagnosis for many of our patients, it also comes with new challenges that we must recognize and address.  相似文献

The generate–recognize model and the relational–item-specific distinction are two approaches to explaining recall. In this study, we consider the two approaches in concert. Following Jacoby and Hollingshead (Journal of Memory and Language 29:433–454, 1990), we implemented a production task and a recognition task following production (1) to evaluate whether generation and recognition components were evident in cued recall and (2) to gauge the effects of relational and item-specific processing on these components. An encoding task designed to augment item-specific processing (anagram-transposition) produced a benefit on the recognition component (Experiments 13) but no significant benefit on the generation component (Experiments 13), in the context of a significant benefit to cued recall. By contrast, an encoding task designed to augment relational processing (category-sorting) did produce a benefit on the generation component (Experiment 3). These results converge on the idea that in recall, item-specific processing impacts a recognition component, whereas relational processing impacts a generation component.  相似文献

To compare community diagnoses of Autism Spectrum Disorder (ASD) reported by parents to consensus diagnoses made using standardized tools plus clinical observation. 87 participants (85% male, average age 7.4 years), with reported community diagnosis of ASD were evaluated using the Autism Diagnostic Observation Schedule) (ADOS-2), Differential Ability Scale (DAS-II), and Vineland Adaptive Behavior Scales (VABS-II). Detailed developmental and medical history was obtained from all participants. Diagnosis was based on clinical consensus of at least two expert clinicians, using test results, clinical observations, and parent report. 23% of participants with a reported community diagnosis of ASD were classified as non-spectrum based on our consensus diagnosis. ASD and non-spectrum participants did not differ on age at evaluation and age of first community diagnosis. Non-verbal IQ scores and Adaptive Behavior Composite scores were significantly higher in the non-spectrum group compared to the ASD group (104.5?±?21.7 vs. 80.1?±?21.6, p?<?.01; 71.1?±?15 versus 79.5?±?17.6, p?<?.05, respectively). Participants enrolled with community diagnosis of PDD-NOS were significantly more likely to be classified as non-spectrum on the study consensus diagnosis than Participants with Autism or Asperger (36% versus 9.5%, Odds Ratio?=?5.4, p?<?.05). This study shows suboptimal agreement between community diagnoses of ASD and consensus diagnosis using standardized instruments. These findings are based on limited data, and should be further studied, taking into consideration the influence of DSM 5 diagnostic criteria on ASD prevalence.  相似文献

Recent research highlights the importance of transdiagnostic factors of psychopathology, particularly in understanding comorbidity. Repetitive negative thinking (RNT) is one such factor, which may elucidate anxiety-depression comorbidity. The Response to Anxiety Questionnaire (RAQ) aims to evaluate repetitive negative thinking (RNT) related to anxiety-depression comorbidity, specifically hopelessness and rumination about anxiety symptoms. Anxious hopelessness is negative thoughts about the future due to anxiety symptoms, and anxious rumination includes negative evaluations of the meaning of anxiety symptoms, therefore the current study assessed the RAQ in three studies. We used exploratory and confirmatory factor analysis methodologies to examine the factor structure of the RAQ. In addition, we tested indirect effects of the two factors of RAQ (Rumination and Hopelessness) between anxiety and depression, and tested measure convergent validity. Results of the current study provide additional support for the psychometric properties of the RAQ, suggesting a two factor makeup (hopelessness, rumination), as well as its use in predicting anxiety and depressive symptoms.  相似文献

Feeling emotionally close to others during social interactions is a ubiquitous and meaningful experience that can elicit positive affect. The present study integrates functional magnetic resonance imaging (fMRI) and ecological momentary assessment (EMA) to investigate whether neural response to social reward (1) is related to the experience of emotional closeness and (2) moderates the association between emotional closeness and positive affect during and following social interactions. In this study, 34 typically developing adolescents (ages 14–18 years) completed a social-reward fMRI task, a monetary-reward fMRI task, and a 2-week EMA protocol regarding their social and affective experiences. Adolescents with greater right posterior superior temporal sulcus/temporoparietal junction (pSTS/TPJ) response to social reward reported greater mean momentary emotional closeness. Neural response to social reward in the right pSTS/TPJ moderated how strongly momentary emotional closeness was associated with both concurrent positive affect and future peak happiness, but in different ways. Although emotional closeness had a significant positive association with concurrent positive affect among adolescents at both high and low right pSTS/TPJ response based on a follow-up simple slopes test, this association was stronger for adolescents with low right pSTS/TPJ response. In contrast, emotional closeness had a significant positive association with future peak happiness among adolescents with high right pSTS/TPJ response, but not among those with low right pSTS/TPJ response. These findings demonstrate the importance of neural response to social reward in key social processing regions for everyday experiences of emotional closeness and positive affect in the context of social interactions.  相似文献

This paper examines regulatory responses to the presence of previously undetected and unlabelled nanoparticles in the Australian food system. Until 2015, the Australian regulatory body Food Standards Australia New Zealand (FSANZ) denied that nanoparticles were present in Australian food. However, and despite repeated claims from Australia’s food regulator, research commissioned by civil society group Friends of the Earth has demonstrated that nanoparticles are deliberately included as ingredients in an array of food available for sale in Australia. This paper critically examines how nanoparticles have come to be integrated into Australia’s food system under the radar of Australia’s food regulator. Our case study of FSANZ—including its responses to the civil society-led science that determined the existence of nanoparticles in Australian food—raises a number of important questions about the governance of risk in relation to emerging technologies such as nanotechnology. In this paper, we argue that FSANZ’ response to the presence of nanotechnology in Australia’s food system is an example of ‘governing with ignorance’. This is demonstrated via the denial and dismissal of science claims as a basis for limited regulatory intervention. FSANZ’ response intersects with the centrality of commercial interests in shaping science research and commercialisation, alongside the ‘hands off’ approach to regulation that is characteristic of neoliberal governance approaches. We conclude by arguing that in the current food governance framework, and alongside a paucity of impact science, civil society plays a vital role in attempts to democratise the Australian food system.  相似文献
