There are a myriad of potentially harmful developmental outcomes associated with infant digital media use. Studies revealing risk associated with early media use have informed the current American Academy of Pediatrics (AAP) recommendations that discourage most digital media use among children under 18 months of age. Recent research advances, however, suggest potential benefits of technology engagement in this age group. Additionally, surveys of parents reveal that most infants engage with digital media for at least 30 min a day, exceeding the AAP recommendations. In response to these discoveries and cultural trends, some scholars have made compelling cases to adapt the AAP guidelines for infants. A helpful model for developing infant digital media use guidelines for families may be the harm reduction approach. The intent of this review is to suggest adaptations to the AAP guidelines for infant media engagement using a harm reduction framework. This review describes the challenge of restrictive guidelines, briefly summarizes the harm reduction approach, provides a review of risks and benefits associated with infant media use in each developmental domain (physical, cognitive, and socioemotional), summarizes correlates of infant screen media use, and examines intervention strategies for reducing screen time. The paper concludes with examples of possible adaptations to current AAP infant media use recommendations using harm reduction and bioecological frameworks. 相似文献

This research reports a novel investigation into the comparative effects of positive and negative direct and extended intergroup contact on intergroup orientations. It tested the generality of the positive–negative asymmetry effect among majority (N = 357) and minority (N = 101) group members in Iceland. Little evidence of asymmetry was observed: the beneficial effects of positive contact were mostly as strong as the detrimental effects of negative contact, for both direct and extended contact. However, evidence was found for alternative interaction models in which positive contact buffers the negative effects of negative contact, and negative contact enhances the benefits of positive contact. These interaction effects were found only for direct contact and principally in the majority group, but were also found for the minority group, though more weakly. No interaction was observed for extended contact. It appeared that differential group salience elicited by positive and negative contact could partly contribute to the explanation of the observed effects, at least in the majority sample. 相似文献

Introduction
Historically focused on waste sorting, waste management recently integrates its complementary components: reuse and reduction.Objective
“Pay as you throw” systems are presently fostered by the French prevailing legislation. In this context, our research was designed to assess the relevance of a less coercive approach based on tailored feedback.Method
Thirty-four households took part in the experiment and were divided into two conditions. Households in the feedback condition received weekly information about their residual waste weight during 14 weeks while those in the control condition received no information.Results
Households in the feedback condition reduced their waste weight between the baseline period and the experimental period significantly more than the control condition.Discussion
Interviews of participants and literature review about the feedback approach enables us to suggest improvements and relevant futures studies. 相似文献154.
The effects of type of instruction,animacy cues,and dimensionality of objects on the shape bias in 3‐ to 6‐year‐old children 下载免费PDF全文

Robust evidence exists for the shape bias, or children's tendency to extend novel names and categorize objects more readily on the basis of shape than on other object features. However, issues remain about the conditions that affect the shape bias and its importance as a linguistic device. In this research, we examined how type of instruction (common noun naming, proper noun naming, same kind, and goes with), animacy of objects (animate, inanimate), and dimensionality of objects (two‐dimensional, three‐dimensional) affect the shape bias in 3‐ to 6‐year‐old children. Overall, all children showed strong use of the shape bias with categorization (same kind, goes with) instructions, the former in line with the shape‐as‐cue theory. Additionally, the shape bias was quite robust in the inanimate condition, regardless of type of instruction or dimensionality of objects. However, in the animate condition, a proper noun naming instruction coupled with an animate object cue reduced the shape bias across both two‐ and three‐dimensional objects. Implications of these findings are presented.
Highlights
- This study assessed the “shape bias,” a linguistic strategy young children routinely use when confronted with the task of extending a novel name from one object to another.
- Novel name extension and categorization tasks were used in this study.
- Shape bias was affected by the type of instructions, animacy of objects, and dimensionality of objects.

Two experiments tested whether nostalgia is a resource for fighting ageism. In Experiment 1, younger adults who recalled a nostalgic (vs. ordinary) encounter with an older adult showed a more positive attitude towards older adults, mediated by greater inclusion of older adults in the self (IOGS). In Experiment 2, these findings were replicated and extended with a subtle nostalgia manipulation. Younger adults identified an older, familiar adult, before writing about an encounter with this person that was characterized by either central (e.g., keepsakes and childhood) or peripheral (e.g., wishing and daydreaming) features of the construct of nostalgia (i.e., prototype). Participants who recalled a central (vs. peripheral) nostalgic encounter reported greater social connectedness, which predicted increased IOGS. In turn, increased IOGS was associated with a lower desire to avoid older adults. Several alternative explanations for the intergroup benefits of nostalgia were ruled out. The research established that nostalgia qualifies as a resource for combatting ageism. 相似文献

The primary way that explanations are constructed in cognitive psychology is by methodological functionalism: in short, functionally defined components are proposed in order to explain how inputs (i.e., stimuli from the environment) are turned into behavior. But despite its close association with cognitive psychology, methodological functionalism is a technique that can be used to describe any natural system. I look at how methodological functionalism has fared when used by other special sciences and what lessons can be learned from these cases. Three explanations of chemical and biological systems that were developed using methodological functionalism are examined: Willis’s (1684) explanation of fermentation, Farr’s (mid-1800s) explanation of cholera, and Mendel’s (mid-1800s) explanation of inheritance. The discovery of HIV in the early 1980s, an investigation that rejected methodological functionalism early on, is also discussed. The assessment of methodological functionalism is not positive. This technique has limitations. The implications for cognitive psychology are considered, and one conclusion is that cognitive psychology will eventually cease relying on methodological functionalism. 相似文献

Mindfulness is theorised to improve attention regulation and other cognitive processes. This systematic review examines whether 8-week standardised and manualised mindfulness training programs such as Mindfulness Based Cognitive Therapy (MBCT) and Mindfulness Based Stress Reduction (MBSR) enhances attention, memory and executive function abilities measured by objective neuropsychological tests. Seven databases were searched resulting in 18 studies meeting inclusion criteria for review. Overall studies did not support attention or executive function improvements. We found preliminary evidence for improvements in working memory and autobiographical memory as well as cognitive flexibility and meta-awareness. Short-term mindfulness meditation training did not enhance theorised attentional pathways. Results call into question the theoretical underpinnings of mindfulness, further highlighting the need for a comprehensive theoretical framework. 相似文献

A defence of non‐causal explanations of events is presented in cases where explanation is understood as modal explanation. In such cases the source of modal information is crucial. All explanations implicitly use contrast classes, and relative to a particular contrast we can privilege some difference makers over others. Thinking about changes in these privileged “actual” difference makers is then the source of modal information for any given explanandum. If an actual difference maker is non‐causal, then we have a principled definition of a non‐causal explanation of an event regardless of how much causal information is also contained in the explanans. A demarcation of explanation into causal and non‐causal in this way recovers ordinary language about explanation as well as reflecting genuine differences in practice, such as the in‐principle evidential base for any modal claim. 相似文献

At the heart of the most radical proposals in Stuart Kauffman's Investigations is his attempt to show that we find in evolutionary biology some configuration spaces—the sets of possible developments for any given system—that (unlike those in traditional physics of Newtonian, relativistic, and quantum stripes) cannot be completely described in advance. We bring Charles Peirce's work on the philosophy of continuity to bear on the problem and discover, first, that Kauffman's arguments do not succeed; second, that Peirce's metaphysics provide new and sounder arguments for the same propositions; third, that Peirce's rigorous but nonstandard treatment of mathematical continuity shows great promise for modeling the unpredictability and growth we find in evolutionary biology; fourth, that it also strengthens a development only hinted at by biologists thus far—the inevitable involvement of the observer's mind in constituting the objects of science. We close with a logical argument for the surprising relevance of metaphysical hypotheses in the natural sciences and with suggestions for future work that will connect these questions to what Kauffman terms the “narrative stance” in biology. 相似文献
