In this research, 10- to 12- and 13- to 15-year-old children were presented with very simple addition and multiplication problems involving operands from 1 to 4. Critically, the arithmetic sign was presented before the operands in half of the trials, whereas it was presented at the same time as the operands in the other half. Our results indicate that presenting the ‘x’ sign before the operands of a multiplication problem does not speed up the solving process, irrespective of the age of children. In contrast, presenting the ‘+’ sign before the operands of an addition problem facilitates the solving process, but only in 13 to 15-year-old children. Such priming effects of the arithmetic sign have been previously interpreted as the result of a pre-activation of an automated counting procedure, which can be applied as soon as the operands are presented. Therefore, our results echo previous conclusions of the literature that simple additions but not multiplications can be solved by fast counting procedures. More importantly, we show here that these procedures are possibly convoked automatically by children after the age of 13 years. At a more theoretical level, our results do not support the theory that simple additions are solved through retrieval of the answers from long-term memory by experts. Rather, the development of expertise for mental addition would consist in an acceleration of procedures until automatization. 相似文献
Identifying what is, and what is not an advertisement is the first step in realizing that an advertisement is a marketing message. Children can distinguish television advertisements from programmes by about 5 years of age. Although previous researchers have investigated television advertising, little attention has been given to advertisements in other media, even though other media, especially the Internet, have become important channels of marketing to children. We showed children printed copies of invented web pages that included advertisements, half of which had price information, and asked the children to point to whatever they thought was an advertisement. In two experiments we tested a total of 401 children, aged 6, 8, 10 and 12 years of age, from the United Kingdom and Indonesia. Six‐year‐olds recognized a quarter of the advertisements, 8‐year‐olds recognized half the advertisements, and the 10‐ and 12‐year‐olds recognized about three‐quarters. Only the 10‐ and 12‐year‐olds were more likely to identify an advertisement when it included a price. We contrast our findings with previous results about the identification of television advertising, and discuss why children were poorer at recognizing web page advertisements. The performance of the children has implications for theories about how children develop an understanding of advertising. 相似文献

The social dominance–environmentalism nexus proposes that orientations for inequality and domination are expressed both in human–human and human–nature relations. In two studies, the present work applies and extends this proposition to understand endorsement of environmental values, concern with climate change, support for climate policies, and responsibility for climate action. In study one, using a representative random sample from Portugal (N = 1270, 53.3% female; European Social Survey, ESS8), social dominance orientation showed unique associations with concern with climate change. Moreover, opposition to immigration (as expression of anti-egalitarianism in intergroup relations) showed unique associations with all four measures of environmentalism. In study two, multi-level analyses using representative random samples from 20 other countries in Europe (N = 38830, 51.5% female; ESS8) confirmed the associations between opposition to immigration and environmentalism, controlling for a set of sociodemographic covariates, political orientation, and nesting at the country level. However, there were differences in the strength and direction of these associations based on country levels of societal development (i.e., Human Development Index; HDI). These differences reinforce the notion that context or situational variables may shape the links between diverse expressions of (anti-)egalitarianism and (anti-)environmentalism. Inputs for applied research on hierarchy-affirming tendencies toward others and the natural environment are proposed and discussed. 相似文献
Cet article explore les interactions entre politiques de GRH et facteurs de contexte dans un processus de changement organisationnel. Nous présentons d'abord une typologie de modèles de GRH, dans la lignée des écrits de Mintzberg sur les configurations organisationnelles. Nous développons ensuite une vision contingente des questions de GRH—mettant en évidence l'influence de certains facteurs de contexte, suivie d'une vision plus politique qui reflète les jeux de pouvoir entre les différents protagonistes, mobilisant chacun des éléments spécifiques du contexte. Enfin, nous offrons une appréhension plus concrète du cadre d'analyse contextualiste en en discutant l'application à une étude de cas dans le secteur agro-alimentaire. This paper explores the interactions between HRM practices and contextual factors in a process of organisational change. We first present a typology of HRM models, in line with Mintzberg's organisational configurations. We then develop a contingent view on HRM issues—highlighting the influence of some contextual factors—followed by a more political view which reveals the power games between the different stakeholders, each of them enacting specific contextual factors. Finally, we give a more concrete understanding of the contextualist framework discussing its application to a case study in the alimentary sector. 相似文献
AbstractBackground: It is increasingly recognized that transgender young people require affirming medical care, however the provision of such care may be mitigated by the availability of services and the views of parents.Aims: This study aimed to explore the views of Australian transgender young people (aged 11–17) and their parents with regards to medical treatment.Methods: Ten qualitative interviews were conducted with parent-child dyads in two Australian states. Thematic analysis was undertaken on responses to interview questions related to family relationships, views about medical treatment (specifically hormone blockers and hormones), and the relationship between medical treatment and sense of self.Results: Themes developed focused on the importance of strong supportive parent-child relationships, the meaning of and access to hormone blockers, and the meaning of and access to hormones.Discussion: The paper concludes by discussing the implications of the findings for clinical services, particularly in relation to supporting parents to be affirming of a transgender child, the need to prepare transgender young people and their parents for the passage of time in regards to medical treatment, and the need to focus on expectations in regards to sense of self in relation to medical treatment. 相似文献
Objective: Limited research has focussed on the development of traumatic stress symptoms following an amputation due to a chronic disease such as Diabetes. This study analysed whether coping strategies, anxiety and depression symptoms, sociodemographic and clinical variables were related to traumatic stress symptoms in a sample of patients who had undergone a lower limb amputation.
Design: A longitudinal design with three assessments, one month (T1), six (T2) and ten months after an amputation surgery (T3), included 144 patients.
Main outcome measures: IES-R, WOC and HADS.
Results: Traumatic stress symptoms were prevalent at T1 (M?=?15.65, SD?=?15.40) and probable PTSD was observed in 13.9% patients. Presence of pain, high level of anxiety symptoms and emotion-focused strategies contributed to traumatic stress symptoms, and the period between T1 and T2, was critical. Six to ten months (Λ?=?0.871, F (2,84) =6.245, p=. 003), after surgery, symptoms tended to decrease 0.122 units (SE?=?0.032, p?=?0.002) per assessment.
Conclusions: Findings raise awareness to the need of urgent identification of traumatic stress symptoms in medically ill patients who underwent a lower limb amputation, given the prevalence of traumatic stress symptoms right after surgery and in the following six months. 相似文献
