Food rejection and the development of food category-based induction in 2–6 years old children

We studied children’s inductive inferences within the domain of food categories. There has so far been little research on inductive reasoning about food among children, despite the theoretical and practical importance of knowing what knowledge children bring to the table and how they use it. We tested the hypotheses that children’s food category-based induction performances and their food rejection are negatively correlated, and that these performances are influenced by the colour typicality of the food items. We recruited 126 children aged 2–6 years, and administered a category-based induction task. Participants were successively shown 8 sets of three pictures containing one target picture (a vegetable) and two test pictures (a vegetable dissimilar in colour to the target picture and a fruit similar in colour to the target picture). For each set, participants were told a novel property about the target picture and asked to generalise this property to one of the two test pictures. Additionally, the parents of each child filled out a questionnaire about his or her food rejection tendencies. Results on accuracy (i.e. if participants generalised the properties according to category membership, not perceptual similarity) provided the first empirical evidence in favour of a negative relationship between children’s food rejection and food category-based induction.     

急性创伤青年患者的心理健康水平与小组干预

为了探讨急性创伤青年患者的心理健康水平及小组干预对策,采用三种国际通用量表（SCL-90、HAMA、HAMD）对160例急性创伤青年患者进行测评,在给予传统心理护理的同时,进行小组干预,然后比较患者干预前后心理健康水平;并以既往同种病例为对照,比较治疗效果。结果显示,86．25％的急性创伤青年患者存在有不同程度的心理障碍。通过小组干预后,患者心理健康水平明显提高;患者的临床疗效明显改善。因此小组干预可显著改善急性创伤青年患者的心理应激水平,提高临床疗效。

The acquisition of scientific knowledge: the influence of methods of questioning and analysis on the interpretation of children's conceptions of the earth

Studies of children's knowledge of the Earth have led to very different conclusions: some appear to show that children construct their own, non‐scientific ‘theories’ (mental models) of the flat, hollow or dual Earth. Others indicate that many young children have some understanding of the spherical (scientific) Earth, and that their knowledge lacks the coherence of mental models. The reasons for these contrasting views were tested by interviewing French children (N = 178) aged 5–11 years and varying the different methods used in previous research, namely the types of questions (open and forced‐choice), the form of representation (two‐dimensional pictures and three‐dimensional models), and the method of analysis (the mental model theorists' coding scheme and a statistical test for associations using MANOVA). Forced‐choice questions resulted in higher proportions of scientific answers than open questions, and children appeared to have naïve mental models of the Earth only when the mental model theorists' coding scheme was used. These findings support the view that children tend to have ‘fragments’ of scientific knowledge, and that naïve mental models of the Earth are methodological artifacts.

A longitudinal assessment of the home literacy environment and early language

This longitudinal assessment concentrated on the relation between the home literacy environment (HLE) and early language acquisition during infancy and toddlerhood. In study 1, after controlling for socio‐economic status, a broadly defined HLE predicted language comprehension in 50 infants. In study 2, 27 children returned for further analyses. Findings revealed that the HLE measured in infancy predicted language production in toddlerhood and maternal redirecting behaviours measured in toddlerhood were negatively associated with expressive language. Results across both studies indicate the importance of a broadly defined HLE (including joint attention and parent–child conversation) for language development. Taken together, these findings highlight the importance of the HLE in supporting both receptive and expressive vocabulary growth in the second and third years of life.

‘I Remember When I Learned That!’ developmental and gender differences in children's memories of learning episodes

Eighty 4‐ to 9‐year‐old children answered factual knowledge questions in math, science and social studies during one‐on‐one interviews. Children indicated whether they had known or guessed each answer, and whether they (a) remembered the moment they learned the answer (episodic response) or (b) did not remember. For episodic responses, children provided memory narratives of learning episodes. One third of children's responses identified a learning episode. There was a developmental trend in which older children were more episodic than younger children, and when children knew and provided correct answers, there was a gender difference in which females were more episodic than males. Developmental and gender differences in the characteristics of memory narratives were also apparent. Copyright © 2010 John Wiley & Sons, Ltd.     

Media exposure, internalization of the thin ideal, and body dissatisfaction: comparing Asian American and European American college females

Internalization of the thin ideal mediates the media exposure-body dissatisfaction relation in young adult European American females. There is little related research on Asian Americans. We used structural equations modeling to test: (1) whether media exposure was associated with body dissatisfaction in Asian American young adult females, (2) internalization of the thin ideal mediated any such association, and (3) whether the mediational model provided equivalent fit for European American and Asian American samples. Participants were 287 college females (154 Asian Americans, 133 European Americans). Internalization of the thin ideal explained the media exposure-body dissatisfaction association equally well for both groups. Results suggest that Asian Americans may be employing unhealthy weight control behaviors, and may be prone to developing eating disorders, at rates similar to European American young adult females. Clinicians need to screen carefully for body dissatisfaction, unhealthy weight control behaviors, and eating disorders in Asian American females.     

Measuring gratitude at work

ABSTRACT

The role of gratitude in the workplace is understudied, despite its potential for promoting well-being and achievement in organizational contexts. We developed and evaluated a measure of workplace-specific gratitude called the Gratitude at Work Scale (GAWS). In Study 1 (N = 207), we used exploratory and confirmatory factor analyses to identify a two-factor structure. The two subscales (Gratitude for Supportive Work Environment, Gratitude for Meaningful Work) had good estimated internal consistency and incrementally predicted burnout after controlling for trait gratitude and workplace satisfaction. In Study 2 (N = 269), we replicated the GAWS two-factor structure, found further evidence for construct validity, and uncovered strong two-week temporal stability. In Study 3 (N = 161), the GAWS was sensitive to manipulations of workplace attitudes following a writing task. The GAWS has initial psychometric support and may be useful when studying workplace functioning and well-being.

Sustainable development goals and nationally determined contributions: the poor fit between agent-dependent and agent-independent policy instruments

Sustainable Development Goals (SDGs), which serve as the primary feature of the 2030 Agenda for Sustainable Development, and Nationally Determined Contributions (NDCs), which serve as a vital instrumental of the UNFCCC’s Paris Agreement, have clear synergies. Both are focused, in part, on responding to challenges presented to human well-being. There are good practical reasons to integrate development efforts with a comprehensive response to climate change. However, at least in their current form, these two policy instruments are ill-suited to this task. Where SDGs are focused on supporting considerations of human flourishing to which policy needs to respond, NDCs, in their current form, are dependent on the determinations of the nations that generate them. I conclude that the best means of integrating these two policy initiatives require moving past the subjective foundations of NDCs.
