NEWBORNS FORM "PROTOTYPES" IN LESS THAN 1 MINUTE 总被引:1,自引:0,他引:1
Abstract— Past research demonstrated that newborns looked longer at live faces and two-dimensional still images of the mother than at the faces and images of strangers (Bushnell, Sai, & Mullin, 1989; Field, Cohen, Garcia, & Greenberg, 1985; Walton, Bower, & Bower, 1992). This study examined schema (prototype) theory as a basis for newborn's preference for the mother's face by creating composite (prototype) faces with a pixel averaging technique. Results obtained with a preferential operant-sucking procedure indicated that formation of a representation of faces was rapid. Newborns preferred to look at a composite of presented faces rather than a composite of unseen faces on the first-look presentation of each. The effect faded over the duration of the experiment. 相似文献

In a rapidly developing crisis such as the COVID-19 pandemic, people are often faced with contradictory or changing information and must determine what sources to trust. Across five time points (N = 5902) we examine how trust in various sources predicts COVID-19 health behaviors. Trust in experts and national news predicted more engagement with most health behaviors from April 2020 to March 2022 and trust in Fox news, which often positioned itself as counter to the mainstream on COVID-19, predicted less engagement. However, we also examined a particular public health behavior (masking) before and after the CDC announcement recommending masks on 3 April 2020 (which reversed earlier expert advice discouraging masks for the general public). Prior to the announcement, trust in experts predicted less mask-wearing while trust in Fox News predicted more. These relationships disappeared in the next 4 days following the announcement and reversed in the 2 years that follow, and emerged for vaccination in the later time points. We also examine how the media trusted by Democrats and Republicans predicts trust in experts and in turn health behaviors. Broadly we consider how the increasingly fragmented epistemic environment has implications for polarization on matters of public health. 相似文献

Patterns of mean-level change in personality traits across the life course: a meta-analysis of longitudinal studies 总被引:9,自引:0,他引:9
The present study used meta-analytic techniques (number of samples = 92) to determine the patterns of mean-level change in personality traits across the life course. Results showed that people increase in measures of social dominance (a facet of extraversion), conscientiousness, and emotional stability, especially in young adulthood (age 20 to 40). In contrast, people increase on measures of social vitality (a 2nd facet of extraversion) and openness in adolescence but then decrease in both of these domains in old age. Agreeableness changed only in old age. Of the 6 trait categories, 4 demonstrated significant change in middle and old age. Gender and attrition had minimal effects on change, whereas longer studies and studies based on younger cohorts showed greater change. 相似文献

Mental fatigue influence on effort-related cardiovascular response: difficulty effects and extension across cognitive performance domains 总被引:2,自引:0,他引:2

Two experiments investigated cardiovascular effects of mental fatigue as a function of (1) the difficulty of the cognitive
challenge with which participants were confronted, and (2) the relevance of that challenge to the activity that instigated
the fatigue. In the first, participants performed an easy (fatigue low) or difficult (fatigue high) counting task and then
were presented an arithmetic challenge (task B relevance high) or a scanning challenge (task B relevance low) with instructions
that they would avoid a noise if they attained a modest performance standard. Analysis of blood pressure responses assessed
during the work periods revealed fatigue main effects, reflecting stronger responses for High Fatigue participants, regardless
of the character of the second task. In the second, the procedure was the same except that it included a high performance
standard and provided the chance to win a prize. Analysis of the pressure data revealed fatigue x work period interactions,
reflecting relatively stronger responses among High Fatigue participants in work period 1, but relatively weaker responses
among these participants in work period 2. Results confirm previous findings and support an analysis of fatigue influence
on effort and associated cardiovascular responses. They also argue against the idea that mental fatigue influence may be confined
to relevant cognitive performance realms.

This investigation explored the extent to which an economic recession predicted changes in college students' optimism about the length and quality of their futures. In a cross‐sectional design, college students in the United States rated their likelihood of divorcing, being unhappy in their career, and living past age 60, at time points before, during, and in the aftermath of an economic recession (2007–2010). Economic indicators, particularly gas prices, predicted decreased optimism as the indicators worsened. After the recession, however, optimism rebounded. The findings reveal that people's expectations for their personal futures are generally sensitive to the state of the national economy. 相似文献

The Convention on the Rights of the Child detailed an international imperative to fulfilling, protecting, and respecting the rights of every child. In particular, the Convention set out a clear mandate for guaranteeing opportunities for children to be heard on all matters of concern to them. The attainment of these goals involves respecting and valuing children as active participants in the educational process. If fully implemented, the right of children to express views and have them taken seriously, throughout the school environment, would represent one of the most profound transformations in moving towards a culture of respect for children's rights, for their dignity and citizenship, and for their capacities to contribute significantly towards their own well-being. These values and principles are consistent with those of the school psychology profession, thus, school psychologists are encouraged to be at the Center of the process advocating and actualizing the Convention in schools throughout the world. 相似文献
