This study aims to explore age prejudice, and to examine age stereotyping in children and adolescents by adopting the Stereotype Content Model (SCM) as a theoretical framework. It was hypothesised that children are socialised into adopting an ambivalent representation of old age (socialisation hypothesis) and that this cognitive bias becomes weaker in adolescence due to greater cognitive maturity (developmental hypothesis). By analysing representative data from Portugal (European Social Survey; N = 2367), it was ascertained that the ambivalent age stereotype (higher evaluations of warmth than competence for older people) is indeed a shared social representation of older people in Portuguese society. A total of 103 Portuguese children (6–10 year olds) and adolescents (11–15 year olds) were then sampled from a local school and responded to age‐appropriate measures assessing age prejudice as well as age stereotypes. Contrary to previous studies, the findings do not provide evidence for the existence of age prejudice because both children and adolescents reported positive feelings towards older people. However, the socialisation hypothesis was corroborated by showing that the ambivalent old age stereotype was already present in childhood. Contrary to the stipulated developmental hypothesis, the magnitude of this cognitive bias was very similar in adolescence.  相似文献

In recent years, substructural approaches to paradoxes have become quite popular. But whatever restrictions on structural rules we may want to enforce, it is highly desirable that such restrictions be accompanied by independent philosophical motivation, not directly related to paradoxes. Indeed, while these recent developments have shed new light on a number of issues pertaining to paradoxes, it seems that we now have even more open questions than before, in particular two very pressing ones: what (independent) motivations do we have (if any) for restrictions on structural rules, and what to make of the plurality of new logics emerging from these restrictions, i.e. how to ‘choose’ among the different options. In this paper, we address these two questions from the perspective of a dialogical conception of logic that we've been advocating in recent years. We will argue that dialogical interpretations of structural rules, that is, as rules determining specific properties of the dialogues in question, provide a conveniently neutral framework to adjudicate between the different substructural proposals that have been made in the literature on paradoxes.  相似文献

The perception of posture may allow workers to discern sensations associated with physical overload and potential tissue damage. In an occupational context, the classification of body postures in ranges of amplitude has been useful for researchers and ergonomists interested in evaluating the exposure of workers to uncomfortable and potentially harmful postures. In this paper we describe measurements, using photographs and electrogoniometry of the angle of flexion of the trunk and of the thoracolumbar segment, respectively, adopted according to the verbal categories of mild, moderate, and severe flexion, as requested by the experimenter. The results showed no differences between the groups of subjects, but significant differences occurred in the classification of the movement amplitude per verbal categories.  相似文献

This longitudinal study presents the first examination of the relation between positive psychology constructs, mental health and academic achievement of students in Portugal. Using a sample of 367 middle-school students, the study revealed that crosssectional and longitudinal patterns of correlations between positive variables were consistent with expectations for the most part and suggested that hope, life satisfaction and self-worth have meaningful relations with mental health and academic achievement. In addition, no significant changes were found between the variables in study across the administrations and throughout the two cohorts, and all the variables in study demonstrate moderate to high stability across a 1- and 2-year time frame. Hope predicts students?? academic achievement, and life satisfaction was the strongest predictor of mental health, over 2-years. The implications of the findings are discussed with reference to prior studies and for future research.  相似文献

We examined if perfectionism and the perception of being an anxious person were associated with more negative infant temperament ratings by the mothers. 386 women (mean age = 30.08; standard deviation = 4.21) in their last trimester of pregnancy completed the Multidimensional Perfectionism Scale (MPS), the Beck Depression Inventory-II (BDI-II) and an item about their perception of being or not an anxious person. The Portuguese version of the Diagnostic Interview for Genetic Studies and the Operational Criteria Checklist for Psychotic Illness were used to generate diagnoses according to DSM-IV and ICD-10 criteria. After delivery, women completed eight items of the Difficult Infant Temperament Questionnaire (developed by our team) and filled in, again, the BDI-II and were interviewed with the DIGS. Women with depression (DSM-IV/ICD-10) and probable cases of depression using different cut-offs adjusted to Portuguese prevalence (BDI-II), in pregnancy and postpartum, were excluded. The Difficult Infant Temperament Questionnaire showed to have factorial validity and internal consistency. There was a statistically significant negative correlation between perfectionism total scale score and item 6 from the temperament scale (“is your baby irritable or fussy?”). Considering MPS 3-factor solution found for pregnancy there was also a statistically significant negative correlation between SOP and the same item. Women with low SOP differed from those with medium and high SOP in the total temperament score. Moreover, the low SOP group differed from the medium group on items three and four scores. There were no significant associations with SPP, which is the dimension more closely associated with negative outcomes. There was an association between anxiety trait status (having it or not) and scoring low, medium or high in the infant temperament scale. The proportion of anxious vs. non-anxious women presenting a high score on the infant temperament scale was higher (24.2% vs. 12.9%). Linear regressions showed that SOP (low vs. medium/high) offered a significant contribution to the prediction of total temperament scale score and items 3 and 4 scores, but a logistic regression did not confirm trait anxiety as a significant predictor of mother's infant temperament perception. Concluding, a major result concerns the fact that higher levels of adaptive perfectionism (i.e. SOP) are associated (and predict) a less negative view of their infant's temperament. These results on the effect of mother's anxiety and perfectionism on the child temperament perception might have treatment implications. As perfectionism is not always maladaptive, some of its positive features could be used to enhance women's self-efficacy/sense of parental competence in their role as mothers and positive affect towards their infants. Also, antenatal interventions aimed at minimising anxiety could help to optimise infant temperament outcomes, which could, eventually, also, lead to subsequent maternal and infant mental health better outcomes.  相似文献

The palmar grasp behavior investigation is frequent in evaluation routine of infants. The aim of this study was to determine the reliability of an instrument for measuring palmar grasp strength in infants from birth to four months of age. Thirty-nine healthy infants from both sexes from birth to four months of age were evaluated and divided into three groups (“SC”, “FR”, “BL”) according to the city they came from. The equipment under test is called M-FLEX®, which provides maximum grasp strength (FMAX), mean grasp strength (FMEAN) and grasp time (GRT) values. The repeatability and reproducibility of measures produced by the M-FLEX™ were verified. Three measurements were obtained (M1, M2, M3) from both hands, with the infant's face turned to the right. To calculate the repeatability, the three measures were compared to themselves in each group. For reproducibility, the difference between the averages of M1 of the three variables provided by M-FLEX™ was verified in the three sampling sites. The statistical tests used were ANOVA, Pearson's correlation and calculation of the intra-class correlation coefficient (ICC) with their respective confidence intervals (CI). The M-FLEX™ proved to be an outfit that provides measures capable of characterizing the palmar grasp phenomenon in infants.  相似文献

Predictive testing protocols are intended to help patients affected with hereditary conditions understand their condition and make informed reproductive choices. However, predictive protocols may expose clinicians and patients to ethical dilemmas that interfere with genetic counseling and the decision making process. This paper describes ethical dilemmas in a series of five cases involving predictive testing for hereditary ataxias in Cuba. The examples herein present evidence of the deeply controversial situations faced by both individuals at risk and professionals in charge of these predictive studies, suggesting a need for expanded guidelines to address such complexities.  相似文献

The purpose of this study was to provide additional validity evidence for a model of person–environment fit based on polychronicity, stimulus load, and information processing capacities. In this line of research the confluence of polychronicity and information processing (e.g., the ability of individuals to process stimuli from the environment along five dimensions of information load, interpersonal load, change load, time structure, and activity structure) is applied to the occupational environment. Using magnitude estimation scaling, college students in the United States and Portugal rated 42 occupations across five information processing demand characteristics. Results indicated that occupations could be differentiated by the information load conditions, thus producing a profile of information processing demand characteristics unique to each of the occupations tested. Additional findings provided evidence for the validity of the scaled occupational values; ratings differed reliably across Holland categories, were fairly consistent across the two cultural groups, and showed expected relationships with salary and educational level.  相似文献

The present research evaluates the sensitivity and salience of form-function correlations in contrast with other types of feature correlations (function-function, form-form) in adults and using real object features (from tools and utensils). In Experiment 1, the participants judged the relation between the form and function features of tools. In Experiment 2, participants were asked to generate a second feature related to a given form or function feature. In Experiment 3, participants were asked to make a lexical decision in which form and function features were used as primes and targets. The results showed that even though participants were sensitive to form-function correlations, these were not particularly salient when compared with other feature-type correlations, notably function-function correlations. Our data underline the overall importance of function information to object representations and the impact of the statistical co-occurrence of features when processing object features.  相似文献

In the present studies, we evaluated the contributions of language and sensorimotor information to the representation of abstract and concrete words and the possibility that the organizations of the two types of concepts follow different organizational principles: association, for abstract concepts, and semantic similarity, for concrete concepts. In Study 1, we examined the two strongest associates of concrete and abstract words from published free association norms. Study 2 then extended this analysis to individual data collected with a free association task. Language associations were more important for abstract than for concrete words, but for sensorimotor information no differences were observed between the two types of concepts. Also, no clear evidence was found for different qualitative organizational principles for abstract and concrete concepts. Multiple representational systems thus seem to be engaged in the conceptual processing of abstract and concrete concepts, while it remains to be investigated whether their representations follow different organizational principles.  相似文献
