Prior research supports that infants born very preterm (PT), compared with full term (FT), have early differences in rate of learning and motor control that may hinder their ability to learn challenging motor tasks. Four-month-old infants born FT (= 18) and PT (n = 18) participated in an infant kick-activated mobile task that was scaffolded to motivate progressively higher kicks. We found the FT group learned the association between their leg movements and mobile activation on the second day, but the PT group learned the association on the third day. Both groups of infants increased the height of their kicks on the day they learned the task, compared with their spontaneous kicking height. These findings suggest that infants born PT have the ability to learn challenging motor tasks, such as kicking high, when participating in a task environment that uses scaffolding.  相似文献

There is a growing interest in intergenerational connectivity through intergenerational programs. In this work, a review of intergenerational programs was performed, with focus on the program design and objectives as well as in their outcomes.

We used a systematic review method in which we screened 3,796 articles. After analyzing titles, abstracts, and full paper analysis, 16 articles were retained. Each study was reviewed, and data were extracted related to target population, study design, characteristics of intervention, outcomes, and effectiveness.

Intergenerational programs included educational programs and art, Information technology development, cultural heritage, health education, and therapeutic activities. Most of the programs collected both quantitative and/or qualitative data. Seven studies collected data in the beginning and at the end of the program. Significant diversity in sample size and intervention length was found. Measurement of outcomes was performed in both young and/or elderly group of participants. Programs impact evaluation varied between studies, including validated scales, interviews, observation, focus groups, and conversation analysis, narratives, videotaped sessions, and field notes.

Our study highlighted the diversity in the design of studies and in the program’s effectiveness evaluation. More randomized design studies are required to support researchers and practitioners in the development of future intergenerational programs.  相似文献

ABSTRACT

This study investigated how peers can contribute to cultural minority students’ cultural identity, life satisfaction, and school values (school importance, utility, and intrinsic values) by talking about cultural values, beliefs, and behaviours associated with heritage and mainstream culture (peer cultural socialisation). We further distinguished between heritage and mainstream identity as two separate dimensions of cultural identity. Analyses were based on self-reports of 662 students of the first, second, and third migrant generation in Germany (Mean age = 14.75 years, 51% female). Path analyses revealed that talking about heritage culture with friends was positively related to heritage identity. Talking about mainstream culture with friends was negatively associated with heritage identity, but positively with mainstream identity as well as school values. Both dimensions of cultural identity related to higher life satisfaction and more positive school values. As expected, heritage and mainstream identity mediated the link between peer cultural socialisation and adjustment outcomes. Findings highlight the potential of peers as socialisation agents to help promote cultural belonging as well as positive adjustment of cultural minority youth in the school context.  相似文献

ABSTRACT

Social policies such as paternity leave and parental leave offer fathers the opportunity to be more involved in childcare than earlier generations of fathers. While such policies are increasingly offered by governments around the world, research by the International Network on Leave Policies and Research shows that many European fathers do not take advantage of these benefits, despite fathers’ growing interest in participation in early childcare. This article introduces a special issue devoted to understanding how the workplace can impact European fathers’ interest in and abilities to take leave, a topic that has received relatively little research attention. The articles in the special issue suggest that barriers to European fathers’ leavetaking are deeply embedded in workplace culture and work practices and will be difficult to eradicate without a dramatic challenge to the concept of the male ideal worker, who prioritizes work above family.  相似文献

Abstract

This research introduces a new approach for separating people from their thoughts by anticipating selling them to others. Participants were asked to write down either positive or negative thoughts about fast food on different pieces of paper. Then, participants were randomly assigned to role-play the part of either potential buyers or sellers for an advertising campaign. Finally, all participants indicated their self-esteem (as an additional predictor) and their attitudes towards fast food (as the dependent measure). For high self-esteem participants, anticipating selling thoughts to others reduced the impact of thoughts on attitudes, suggesting that distancing thoughts from a location with high validity (the self) reduced the perceived value of their thoughts. In contrast, for low self-esteem participants, anticipating selling thoughts increased their usage, suggesting that separating thoughts from a location with low validity (the self) increased the perceived value of those thoughts. These findings suggest that thoughts can be associated with high or low validity depending on individual differences in self-esteem.  相似文献

Abstract

The main goal of this introductory article is to provide an overview of some of the main empirical illustrations relevant to the psychology of separating from one’s thoughts. Separating from our own thoughts often involves thinking about our own thoughts (meta-cognition). We describe meta-cognitive processes relevant to how individuals calibrate and control the impact of their thoughts on judgement and behaviour. Amongst other things, this special issue presents us with an opportunity to examine the similarities and differences between key contributions focused on correction and suppression processes, decentering approaches and separating from thoughts by using a variety of techniques. In addition to these paradigms covered in the articles of this special issue, we review other approaches that also involve reducing the impact of thoughts, with special attention to invalidation processes. Additional frameworks relevant to mental separation included in this review are those relevant to non-evaluative observation of thoughts, psychological distance and mental hygiene.  相似文献
