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.

There is now compelling evidence, coming both from animal and human studies that an early exposure to undernutrition is frequently associated with low birth weight and programs HPA axis alterations throughout the lifespan. Although animal models have reported conflicting findings arising from differences in experimental paradigms and species, they have clearly demonstrated that such programming not only affects the brain but also the pituitary corticotrophs and the adrenal cortex. In fetuses, maternal undernutrition reduces HPA axis function and implicates a reduction of placental 11beta-HSD2 activity and a greater transplacental transfer of glucocorticoids (GRs). In young adults, usually only fine HPA axis alterations were observed, whereas in older ones, maternal undernutrition was frequently associated with chronic hyperactivity of this neuroendocrine axis. In humans, evidence of HPA axis dysregulation in people who were small at birth has recently emerged. Thus, we suggest that such alterations in adults may be implicated in the aetiology of several disorders related to the metabolic syndrome as well as to immune or inflammatory diseases. To reverse such programming, recent experimental reports have shown that postnatal environmental interventions, dietary modifications and the use of agents modulating the epigenomic state could partly restore physiological functions and thus open new therapeutic strategies. 相似文献

A particularly important aspect of executive functioning involves the ability to form and carry out complex plans, that is to say planning. This study aimed to investigate planning in 18 older and 16 younger normal participants using an ecological planning subtask derived from the Behavioural Assessment of the Dysexecutive Syndrome test battery, the "Zoo Map Test." There are two trials. The first trial consists of a "high demand" version of the subtask in which the participants must plan in advance the order in which they will visit designated locations in a zoo (formulation level). In the second, or "low demand" version, the participant is simply required to follow a concrete externally imposed strategy to reach the locations to visit (execution level). The two-way ANOVAs mainly showed more difficulties in elderly adults than in younger adults, more difficulties in formulation level than in execution level, and lastly a greater difference between formulation and execution in older participants than in younger adults. These results suggest that elderly participants have some problems developing logical strategies whereas they are able to execute complex predetermined plans. 相似文献

The authors reexamined, theoretically and empirically, the method proposed by J. J. Collins and C. D. De Luca (1993) for the analysis of center-of-pressure trajectories. The main argument in this article is that Collins and De Luca's approach is not adapted to the analysis of bounded time series and leads to statistical artifacts such as underestimation of the diffusion process for long-term intervals. The open- and closed-loop model developed by Collins and De Luca is a direct consequence of those statistical problems. Applying more classical methods, such as rescaled range analysis or detrended fluctuation analysis, the authors show that center-of-pressure trajectories can be modeled as continuous, antipersistent fractional Brownian motion. More specifically, those trajectories behave like 1/f noise, a ubiquitous feature in adaptive biological systems. 相似文献

To explore an alternative solution more appropriate to clinical standards than random assignment, 42 mothers consulting for a functional (sleep, feeding) or behavior problem of their infant were given the choice between two forms of mother–infant psychotherapy (Psychodynamic or Interaction Guidance). Clinicians, blind to mother's choice, followed a systematic indication procedure and provided a therapeutic recommendation. Results revealed a very high agreement between mother's choice and therapists' recommendation. Examination of patient and pretreatment variables showed no major differences between the two groups resulting from a choice of treatment procedure. This procedure proved to ensure internal validity of the data and was also able to guarantee external validity. Discussion focuses on the methodological and clinical implications of the findings that support the consideration of the patient as an active participant to his/her treatment. © 1998 Michigan Association for Infant Mental Health 相似文献

Evidence-based practice in psychotherapy is gaining ground, but we are in great need of more detailed study concerning some basic aspects: the interrelationships between nonspecific and specific factors and their impact on outcome and the precise observation of what goes on between therapist and patient. A comparison of two forms of mother–infant psychotherapy reveals an important gap between what therapists believe and what they actually do. We describe several components of processes: the contribution of the infant, the treatment of affect, the construction of an interpretative focus, and the relationships between cognitive and emotional contributions. These observations indicate the need for a more realistic appraisal of what goes on in technique applications, as well as for a widening of the definition of technique. © 1998 Michigan Association for Infant Mental Health 相似文献

The purpose was to adapt a brief tool, the Physical Self Inventory-Version b, for the assessment of physical self in adults. The inventory is a refined version of the previously validated version, which was derived from the Physical Self Inventory (25 items). This French validation of the Physical Self-Perception Profile of Fox and Corbin includes a global self-esteem scale. As in the earlier version the current one has 6 single items to assess dimensions of global self-esteem, physical selfworth, sport competence, physical condition, attractive body, and physical strength. Rating is performed on a visual analog scale. Items in the new inventory were stated in the first person and in more general terms to be acceptable to a wider range of subjects. An item of measurement error was added. Analysis of responses of 185 men and 148 women to the new version supported the hierarchical structure. Significant correlations between the scores and constructs like masculinity, neuroticism, and depression indicated external validity. The new inventory showed acceptable psychometric properties for use in idiographic studies. 相似文献

The present study examined the influence of pharmacological modulations of the locus coeruleus noradrenergic system on odor recognition in the mouse. Mice exposed to a nonrewarded olfactory stimulation (training) were able to memorize this odor and to discriminate it from a new odor in a recall test performed 15 min later. At longer delays (30 or 60 min), the familiar odor was no longer retained, and both stimuli were perceived as new ones. Following a post-training injection of the alpha(2)-adrenoceptor antagonist dexefaroxan, the familiar odor was still remembered 30 min after training. In contrast, both the alpha(2)-adrenoceptor agonist UK 14304 and the noradrenergic neurotoxin DSP-4 prevented the recognition of the familiar odor 15 min after the first exposure. Noradrenaline release in the olfactory bulb, assessed by measurement of the extracellular noradrenaline metabolite normetanephrine, was increased by 62% following dexefaroxan injection, and was decreased by 38%-44% after treatment with UK 14304 and DSP-4. Performance of mice in the recall test was reduced by a post-training injection of the beta-adrenoceptor antagonist propranolol or the alpha(1)-antagonist prazosin, thus implicating a role for beta- and alpha(1)-adrenoceptors in the facilitating effects of noradrenaline on short-term olfactory recognition in this model. 相似文献

Within the field‐dominating, multidimensional theory of burnout, burnout is viewed as a work‐specific condition. As a consequence, the burnout syndrome cannot be investigated outside of the occupational domain. In the present paper, this restrictive view of burnout's scope is criticized and a rationale to decide between a work‐specific and a generic approach to burnout is presented. First, the idea that a multidimensional conception of burnout implies a work‐restricted scope is deconstructed. Second, it is shown that the burnout phenomenon cannot be confined to work because chronic, unresolvable stress – the putative cause of burnout – is not limited to work. In support of an integrative view of health, it is concluded that the field‐dominating, multidimensional theory of burnout should abandon as groundless the idea that burnout is a specifically job‐related phenomenon and define burnout as a multi‐domain syndrome. The shift from a work‐specific to a generic approach would allow both finer analysis and wider synthesis in research on chronic stress and burnout. 相似文献
