Habituation – the most basic form of learning – is used to evaluate central nervous system (CNS) maturation and to detect abnormalities in fetal brain development. In the current study, habituation, stimulus specificity and dishabituation of auditory evoked responses were measured in fetuses and newborns using fetal magnetoencephalography (fMEG). An auditory habituation paradigm consisting of 100 trains of five 500 Hz tones, one 750 Hz tone (dishabituator) and two more 500 Hz tones, respectively, were presented to 41 fetuses (gestational age 30–39 weeks) and 22 newborns or babies (age 6–89 days). A response decrement between the first and fifth tones (habituation), an increment between the fifth tone and the dishabituator (stimulus specificity) and an increment between the fifth (last tone before the dishabituator) and seventh tones (first tone after the dishabituator) (dishabituation) were expected. Fetuses showed weak responses to the first tone. However, a significant response decrement between the second and fifth tones (habituation) and a significant increment between the fifth tone and the dishabituator (stimulus specificity) were found. No significant difference was found for dishabituation nor was a developmental trend found at the group level. From the neonatal data, significant values for stimulus specificity were found. Sensory fatigue or adaptation was ruled out as a reason for the response decrement due to the strong reactions to the dishabituator. Taken together, the current study used fMEG to directly show fetal habituation and provides evidence of fetal learning in the last trimester of pregnancy. 相似文献

Somatic phenomena in the countertransference have historically received minimal attention despite evidence of their occurrence in the therapeutic encounter. In the field of Counselling Psychology, there seems to be an apparent gap in the academic coverage and clinical utilisation of therapists’ somatic states. The purpose of this study was to explore therapists’ somatic experiences in the countertransference using a grounded theory methodology, based on a sample of 12 participants that was composed of psychotherapists, counselling and clinical psychologists. The results indicated that therapists made sense of their somatic experiences through a developmental process of ‘relating to the body’ that combined stages of defensive operations, intellectual reflections, attributions of somatic ownership and recognitions of various working patterns in the management of somatic experiences. This study addresses the factors that constituted therapists’ processing of the experience, and the findings suggest that therapeutic work may be affected when psychosomatic phenomena as such become undermined and ignored. 相似文献

ABSTRACT The goal of the current project was to examine whether engagement in intellectual/cultural activities explains the long-term effects of education on cognitive abilities throughout adulthood, and whether it compensates for educational differences in cognitive abilities throughout adulthood. Participants between 18 and 96 years of age completed a comprehensive questionnaire about intellectual/cultural activities that they participated in and performed a wide variety of cognitive tests. There were no mediation effects of engagement in intellectual/cultural activities on the relationship between education and cognitive functioning. In contrast, engagement in intellectual/cultural activities was found to moderate the relations between education and the level of fluid ability, working memory, speed of processing, and episodic memory. Findings suggest that the risk of cognitive decline in people with less education can be reduced via engagement in intellectual and cultural activities throughout adulthood. 相似文献

A number of studies have shown that dogs are sensitive to a human’s perspective, but it remains unclear whether they use an egocentric strategy to assess what humans perceive. We investigated whether dogs know what a human can see and hear, even when the dogs themselves are unable to see the human. Dogs faced a task in which forbidden food was placed in a tunnel that they could retrieve by using their paw. Whereas the dogs could not see the experimenter during their food retrieval attempts, the experimenter could potentially see the dog’s paw. In the first experiment, dogs could choose between an opaque and a transparent side of the tunnel, and in the second experiment, they could choose between a silent and a noisy approach to the tunnel. The results showed that dogs preferred a silent approach to forbidden food but they did not hide their approach when they could not see a human present. We conclude that dogs probably rely on what they themselves can perceive when they assess what the human can see and hear. 相似文献

This study examined the utility of the biopsychosocial model to predict accuracy of weight status perception among Australian adolescents. The factors included in this framework were: age, gender, and BMI-z (biological factors); satisfaction with body weight and shape (psychological factors); socioeconomic status, peer weight (social factors). Cross-sectional data, including measured height and weight, and self-reported weight status, was obtained from 2954 adolescents (mean age = 14.6, 56% male) who participated in the It's Your Move! study. Accuracy of weight status perception was associated with gender, BMI-z, SES, and weight and shape satisfaction. Gender differences in weight status perception were moderated by satisfaction with weight. In boys, weight satisfaction was associated with perceived healthy weight; in girls, it was associated with perceived healthy weight and underweight. Moderately overweight adolescents are most at risk of underestimating their weight status and could benefit from education about the boundaries of the healthy weight range. 相似文献

This paper claims that there is a plausible sense in which validity is a matter of truth preservation relative to interpretations of the sentences that occur in an argument, although it is not the sense one might have in mind. §1 outlines three independent problems: the first is the paradox of the sorites, the second concerns the fallacy of equivocation, and the third arises in connection with the standard treatment of indexicals. §2 elucidates the claim about validity, while §§3–5 show how the three problems outlined can be handled in accordance with it. §6 explains how the claim squares with the traditional idea that validity is related to formality, and in particular with a broadly accepted definition based on that idea, the model-theoretic definition of logical consequence. Unlike other works on the subject, this paper does not focus on necessity. It is not its intention to provide a characterization of necessity that conforms to some ideal of rigour or to some pre-theoretical understanding of validity. What follows can be taken as conditional on the assumption that such a characterization can be provided. 相似文献

Clinical experience suggests that restless legs syndrome (RLS), periodic leg movement (PLM), and attention-deficit hyperactivity disorder (ADHD) may co-occur in both children and adults. The purpose of the present study was to provide an electrocorticography and electromyography evaluation of the spontaneously hypertensive rat (SHR) to investigate the potential of this rat strain as an animal model of RLS–PLM. Initial work focused on evaluating sleep patterns and limb movements during sleep in SHR, having normotensive Wistar rats (NWR) as control, followed by comparison of two treatments (pharmacological–dopaminergic agonist treatment and nonpharmacological–chronic physical exercise), known to be clinically beneficial for sleep-related movement disorders. The captured data strengthen the association between SHR and RLS–PLM, revealing a significant reduction on sleep efficiency and slow wave sleep and an increase on wakefulness and limb movements for the SHR group during the dark period, as compared to the NWR group, effects that have characteristics that are strikingly consistent with RLS–PLM. The pharmacological and nonpharmacological manipulations validated these results. The present findings suggest that the SHR may be a useful putative animal model to study sleep-related movement disorders mechanisms. 相似文献

Regression mixture models have been increasingly applied in the social and behavioral sciences as a method for identifying differential effects of predictors on outcomes. Although the typical specification of this approach is sensitive to violations of distributional assumptions, alternative methods for capturing the number of differential effects have been shown to be robust. Yet, there is still a need to better describe differential effects that exist when using regression mixture models. This study tests a new approach that uses sets of classes (called differential effects sets) to simultaneously model differential effects and account for nonnormal error distributions. Monte Carlo simulations are used to examine the performance of the approach. The number of classes needed to represent departures from normality is shown to be dependent on the degree of skew. The use of differential effects sets reduced bias in parameter estimates. Applied analyses demonstrated the implementation of the approach for describing differential effects of parental health problems on adolescent body mass index using differential effects sets approach. Findings support the usefulness of the approach, which overcomes the limitations of previous approaches for handling nonnormal errors. 相似文献

Much of the literature on practical authority concerns the authority of the state over its subjects—authority to which we are, as G. E. M. Anscombe says, subject “willy nilly”. Yet many of our “willy” (or voluntary) relationships also seem to involve the exercise of practical authority, and this species of authority is in some ways even more puzzling than authority willy nilly. In this paper I argue that voluntary authority relies on a form of voluntary obligation that is akin (in some respects) to the kind of obligation one undertakes in making a promise. Voluntary authority depends, that is, on the possibility of taking on certain obligations more or less at will. It is generated through an interpersonal transaction that involves a directed act of deference, on one side, paired with appropriate uptake of that deference, on the other. Deference, in the relevant sense, should be understood as a normative power that is exercised when agents transfer deliberative discretion to others, undertaking directed obligations to treat others’ directives as content-independent and peremptory reasons. Voluntary authority, thus understood, is both grounded in and constrained by the equal moral authority or autonomy of the participants, since only autonomous agents have the standing to defer in a normatively significant way. 相似文献
