Is the Confirmation Bias Bubble Larger Online? Pre-Election Confirmation Bias in Selective Exposure to Online versus Print Political Information     

George David Hooke Pearson  Silvia Knobloch-Westerwick 《Mass Communication and Society》2019,22(4):466-486

The Internet era has often been blamed for a predominant engagement with attitude-consistent information among citizens (labeled confirmation bias), which is thought to hurt political deliberation. This study offers the first rigorous evidence suggesting that online news fosters greater confirmation bias than traditional media. A 2 × 2 within-subjects experiment presented political articles, varying stance (conservative vs. liberal) and medium (online vs. print); selective exposure was logged or taped. Data were collected during the U.S. 2016 presidential primaries. As expected in the preelection context, partisans whose party was anticipated to lose the election (conservatives) did not exhibit confirmation bias. Liberals showed confirmation bias, but only online, suggesting print contexts reduce confirmation bias.  相似文献

State-Dependent Memory in Infants     

Sabine Seehagen  Silvia Schneider  Katharina Sommer  Laura La Rocca  Carolin Konrad 《Child development》2021,92(2):578-585

Why do infants remember some things and not others? Human infants frequently cycle through different states such as calm attentiveness, wakeful activity, and crying. Given that cognitive processes do not occur in isolation, such fluctuations in internal state might influence memory processing. In the present experiment, declarative memory in 9-month-old infants (N = 96) was heavily state dependent. Infants exhibited excellent retention of a deferred imitation task after a 15-min delay if their state at encoding was identical to their state at retrieval (e.g., calm). Infants failed to exhibit retention if their state at encoding was different from their state at retrieval (e.g., calm vs. animated). Infant memory processing depends on internal cues.  相似文献   

Young Children's Spatial Representations Developed through Exploration of a Desktop Virtual Reality Scene     

Silvia Gabrielli  Yvonne Rogers  Mike Scaife 《Education and Information Technologies》2000,5(4):251-262

Virtual Reality (VR) technology seems to offer the opportunity of designing 3D worlds and navigation activities which provide settings that are close to children's everyday experiences, capitalising on their enthusiasm for videogame-like technologies.This paper describes how different types of exploration of a VR scene by 6[emsp4 ]y-old children affected their performance in a series of spatial tasks. Individual children explored a desktop virtual world where we varied both the visual perspective on the VR scene (route vs. survey view) and the level of exploration control (active vs. passive movement). We measured children's knowledge of the spatial layout of the environment through their memory of objects' location in the virtual scene and through the analysis of their wayfinding abilities within the scene.The results indicate that children were able to develop and display different levels of allocentric knowledge about the virtual world depending on the way they had familiarized with it and on the characteristics of the task demands. This finding contributes to inform the design of VR technologies aimed at supporting or evaluating spatial abilities in children of this age.  相似文献   

The mirror’s curse: Weight perceptions mediate the link between physical activity and life satisfaction among 727,865 teens in 44 countries     

Silvia Meyer  Rebekka Weidmann  Alexander Grob 《运动与健康科学(英文)》2021,10(1):48-54

Purpose:The present study aimed to examine the link between physical activity(PA)and life satisfaction in a large international study of adolescents.We also aimed to test whether overweight and underweight perceptions act as mediators and whether age and sex acted as moderators.Methods:For this purpose,we analyzed data from the Health Behavior in School-aged Children study,which comprises 727,865 observations from 44 nations at 4 measurement occasions.Results:Multilevel analyses revealed a positive link between PA and life satisfaction.In addition,underweight and overweight perceptions mediated the effect of PA on life satisfaction.We further found that age and sex acted as moderators.In older adolescents,stronger effects were found in the links between PA and life satisfaction,PA and overweight perception,and both weight perceptions and life satisfaction.In addition,in female adolescents,the link between overweight perception and life satisfaction was stronger.Conversely,the links between PA and both weight perceptions were stronger for boys.Conclusion:The results suggest that weight perception explains part of the relationship between PA and life satisfaction in adolescents and that these effects vary as a function of age and sex.  相似文献
