People vary dramatically in their calorie estimates of food depending on the information available to them. Prior research has focused on information that is normatively relevant to the number of calories a food contains (e.g., fat content, serving size). The current research examines whether information that is normatively irrelevant to the number of calories a food contains—such as its availability—might also shape people's calorie estimates. Three studies found that a food perceived as limited in availability leads people to estimate the food to contain more calories. Serial mediation analyses revealed that this effect occurs because scarce food is seen as more valuable and expensive, which subsequently induces feelings of resource deprivation. This sense of resource deprivation, in turn, leads to motivated perception, whereby higher calorie estimates are the result of people wanting to acquire more resources. The findings provide insight into the psychology of scarcity and underscore the importance of understanding how contextual factors shape people's calorie estimates and the psychological mechanisms that drive them. 相似文献
We investigated the development of a recently identified white matter pathway, the frontal aslant tract (FAT) and its association with executive function and externalizing behaviors in a sample of 129 neurotypical male and female human children ranging in age from 7 months to 19 years. We found that the FAT could be tracked in 92% of those children, and that the pathway showed age‐related differences into adulthood. The change in white matter microstructure was very rapid until about 6 years, and then plateaued, only to show age‐related increases again after the age of 11 years. In a subset of those children (5–18 years; n = 70), left laterality of the microstructural properties of the FAT was associated with greater attention problems as measured by the Child Behavior Checklist (CBCL). However, this relationship was fully mediated by higher executive dysfunction as measured by the Behavior Rating Inventory of Executive Function (BRIEF). This relationship was specific to the FAT—we found no relationship between laterality of a control pathway, or of the white matter of the brain in general, and attention and executive function. These findings suggest that the degree to which the developing brain favors a right lateralized structural dominance of the FAT is directly associated with executive function and attention. This novel finding provides a new potential structural biomarker to assess attention deficit hyperactivity disorder (ADHD) and associated executive dysfunction during development. 相似文献
Substantial evidence in the behavioral and social sciences has accrued in support of numerous intervention programs and policies bearing on improving the lives of children and families. To this end, Clinical Child and Family Psychology Review features a special journal issue on “Evolving Toward a More Nurturing Society.” The field has achieved numerous advances regarding how to create and promote nurturing environments that foster successful development and prevent psychological and behavioral problems in children and youth. Such advances cut across multiple strategies (e.g., programs and interventions, practices, and public policies), settings (e.g., family, school including preschool and K-12, service sectors, community), domains (e.g., behavioral health, parenting, cognitive and academic functioning, nutrition, physical activity, obesity, safety, and many other domains), and developmental periods of childhood. The special journal issue showcases a sampling of strategies and domains relevant to producing optimal conditions of nurturance for children and families. 相似文献
The success of graduate students relies on factors beyond mere cognitive ability, with fostering peer and professional relationships as definitive influences on achievement. Research shows that positive faculty/student relationships are a significant factor in the success of graduate students and that art-making is an effective way to encourage the reflective thinking needed to nurture these relationships. In this article, we examine the relationship between arts informed pedagogy, specifically the use of a visual/verbal journal, and the formation of graduate relationships. The majority of the students in this collaborative inquiry entered their doctoral program at the same time the research class began and all engaged in an artfully imagined introduction to qualitative research course. 相似文献
Young people’s perspectives about mental health concepts shape both their interactions with sufferers of mental illness and their actions related to their own mental health. The current study employed a cross-sectional qualitative design to explore how adolescents (aged 12–18 years) speak about mental health and illness in order to gain insight into young people’s perceptions and experiences and contribute to shaping approaches to policy and practice. When discussing mental health concepts and appropriate behaviours toward sufferers of mental illness, adolescents conveyed a sense of acceptance and understanding of the potential complexity and severity of mental health problems. In contrast, when discussing mental health in the context of their own lives, a stronger sense of scepticism was conveyed, with students expressing difficulty with the lack of visible markers of mental health and confusion determining authenticity in the mental health states conveyed by their peers. Interestingly, adolescents interviewed commonly conveyed the notion that young people may exaggerate or “fake” a mental illness for personal gain. Adolescent perceptions of mental health and illness hold practical implications for policy and school-based programs aimed at improving mental health knowledge, attitudes and behaviours among youth. 相似文献
Taboo stimuli are highly arousing, but it has been suggested that they also have inherent taboo-specific properties such as tabooness, offensiveness, or shock value. Prior studies have shown that taboo words have slower response times in lexical decision and higher recall probabilities in free recall; however, taboo words often differ from other words on more than just arousal and taboo properties. Here, we replicated both of these findings and conducted detailed item analyses to determine which word properties drive these behavioural effects. We found that lexical-decision performance was best explained by measures of lexical accessibility (e.g., word frequency) and tabooness, rather than arousal, valence, or offensiveness. However, free-recall performance was primarily driven by emotional word properties, and tabooness was the most important emotional word property for model fit. Our results suggest that the processing of taboo words is influenced by distinct sets of factors and by an intrinsic taboo-specific property. 相似文献
This study investigated the impact of ostracism (vs. inclusion) for women in a same-sex vs. opposite-sex group on their cognitive performances. Female participants played Cyberball with other women or men and were either included or excluded. Participants then had to engage in the performance tasks. Results showed that women’s performance was decreased by ostracism in a math task (but not a verbal task) yet only in the same-sex condition. Furthermore, this result was obtained only among participants who did the numeric task first. No effect was observed in the verbal task. Two replications of the initial study were conducted using the math task. The result of the first study has been replicated one time. A meta-analysis revealed a small effect of ostracism on performance in the ingroup condition, whereas the effect seems to be non-existent in the outgroup condition. Results are discussed and future perspectives are proposed. 相似文献
As the cultural dynamic continues to become increasingly complex, it is critical to assess cultural factors that influence practice. The present study considers the treatment preferences of Japanese mothers of children with developmental disabilities. After answering demographic questions, each participant was given four scenarios and asked how they would respond by choosing one of four interventions (differential reinforcement, ignoring, reprimanding, and time-out). Overall, we found that parents preferred differential reinforcement strategies the most. Moreover, parents who reported that their children had a history of involvement with applied behavior analysis were especially likely to choose differential reinforcement. Implications for future research and practice are provided. 相似文献
Objective: This study investigates the impact of HIV diagnosis on subjective social status and if changes are linked to health outcomes.
Design: Two measures of subjective social status, socio-economic and standing in the community were examined in 342 Australian HIV-positive gay men in 2014. Participants recalled ratings at diagnosis were compared with current ratings.
Main outcome measures: Self-reported mental (psychological distress, self-esteem, positive mental health and satisfaction with life) and physical health (self-rated health, CD4 count, viral load).
Results: Half of the participants reported improvements in subjective socio-economic status (59%) or standing in the community (52%) since diagnosis, yet one quarter reported socio-economic status (25%) or standing in the community had decreased (23%). Increases in either measure of subjective social status were linked to higher self-esteem, positive mental health, satisfaction with life and better self-rated health. Decreases in subjective social status, however, were strongly linked to poorer outcomes on all mental health measures. Decreases in standing in the community were also associated with poorer physical self-rated health.
Conclusion: Most participants reported their subjective social status were the same or better since diagnosis. Changes in subjective social status following diagnosis were strongly linked to mental health outcomes. Those who reported a decrease in subjective social status were particularly vulnerable to mental health problems. 相似文献
Drawing on conservation of resources theory, multiplex social networks research, and the emerging conflict involvement perspective, the purpose of this study is to develop and test a multiplex view of conflict that explicitly accounts for the nature of the social relationships between those involved in intrateam conflict and how these multiplex relationships differentially impact team performance. Data were collected from 120 teams engaged in a 4-month business simulation. Relationship conflicts occurring among team members who are friends have a negative impact on team performance, whereas those occurring between non-friends have a positive impact on team performance. Although we also find non-friend task conflicts to be beneficial for team performance, friend task conflicts have no impact on team performance. This study highlights the dark side of workplace friendships and admonishes managers to pay close attention not only to conflicts among employees, but also to the relational closeness of those involved in conflict. The current study provides empirical support for the emerging conflict involvement perspective by explicitly assessing the number of individuals involved in conflict as well as the type of relationships between them. We also extend research on multiplex relationships from the individual to the team level of analysis. Finally, we respond to calls for studies of multiplexity that include both positive and negative relationships. 相似文献
