Morningness-eveningness was assessed in a large sample of adolescents and young adults. Morningness decreased from 12 to 15 years, and then remained on a stable level until about 20 years, when a turn back to morningness occurred. Boys and men were on average more evening-oriented than were girls and women. In detail, significant differences existed at the ages of 16, 18, and 19 years. A quadratic function explained more variance than a linear regression. Composite Scale of Morningness scores are related to puberty scores in boys and girls, and when combining data (i.e., higher pubertal development was related to eveningness).  相似文献

This paper presents a neuroscientific study of aesthetic judgments on written texts. In an fMRI experiment participants read a number of proverbs without explicitly evaluating them. In a post-scan rating they rated each item for familiarity and beauty. These individual ratings were correlated with the functional data to investigate the neural correlates of implicit aesthetic judgments. We identified clusters in which BOLD activity was correlated with individual post-scan beauty ratings. This indicates that some spontaneous aesthetic evaluation takes place during reading, even if not required by the task. Positive correlations were found in the ventral striatum and in medial prefrontal cortex, likely reflecting the rewarding nature of sentences that are aesthetically pleasing. On the contrary, negative correlations were observed in the classic left frontotemporal reading network. Midline structures and bilateral temporo-parietal regions correlated positively with familiarity, suggesting a shift from the task-network towards the default network with increasing familiarity.  相似文献

Phonological theories have raised the notion of a universally preferred syllable type which is defined in terms of its sonority structure (e.g., ). Empirical evidence for this notion has been provided by distributional analyses of natural languages and of language acquisition data, and by aphasic speech error analyses. The present study investigates frequency distributions of syllable types in German, which allows for a rather complex syllable structure, and in neologistic utterances of a German speaking jargon aphasic. The findings suggest that the sonority structure of the patient's neologisms is generally in accordance with the notion of theoretically preferred syllables. Moreover, comparative analyses suggest that the predominance of the preferred syllable type is especially pronounced in the aphasic data. On the basis of these findings, the influence of sonority in impaired phonological lexical processing is discussed.  相似文献

In this paper an empirical theory about the nature of intention is sketched. After stressing the necessity of reckoning with intentions in philosophy of action a strategy for deciding empirically between competing theories of intention is exposed and applied for criticizing various philosophical theories of intention, among others that of Bratman. The hypothesis that intentions are optimality beliefs is defended on the basis of empirical decision theory. Present empirical decision theory however does not provide an empirically satisfying elaboration of the desirability concepts used in these optimality beliefs. Based on process theories of deliberation two hypotheses for filling this gap are developed.  相似文献

Attention is given to a background idea that is often invoked in discussions about reasonable partiality: the idea of a moral division of labour. It is not only a right, but also a duty for professionals to attend (almost) exclusively to the interests of their own clients, because their partial activities are part of an impartial scheme providing for an allocation of professional help to all clients. To clarify that idea, a difference is made between two kinds of division of labour, a technical one and a social one. In order to assess the applicability of the idea of a moral division of labour to professional ethics, journalism is contrasted with other professions.  相似文献

Four experiments examined children's ability to reason about the causal significance of the order in which 2 events occurred (the pressing of buttons on a mechanically operated box). In Study 1, 4-year-olds were unable to make the relevant inferences, whereas 5-year-olds were successful on one version of the task. In Study 2, 3-year-olds were successful on a simplified version of the task in which they were able to observe the events although not their consequences. Study 3 found that older children had difficulties with the original task even when provided with cues to attend to order information. However, 5-year-olds performed successfully in Study 4, in which the causally relevant event was made more salient.  相似文献

New Caledonian crows (Corvus moneduloides) rely heavily on a range of tools to extract prey. They manufacture novel tools, save tools for later use, and have morphological features that facilitate tool use. We report six observations, in two individuals, of a novel tool-use mode not previously reported in non-human animals. Insert-and-transport tool use involves inserting a stick into an object and then moving away, thereby transporting both object and tool. All transported objects were non-food objects. One subject used a stick to transport an object that was too large to be handled by beak, which suggests the tool facilitated object control. The function in the other cases is unclear but seems to be an expression of play or exploration. Further studies should investigate whether it is adaptive in the wild and to what extent crows can flexibly apply the behaviour in experimental settings when purposive transportation of objects is advantageous.  相似文献

There is a shift in evidence-based practice toward an understanding of the treatment elements that characterize empirically supported interventions in general and the core components of specific approaches in particular. The evidence base for behavioral parent training (BPT) and the standard of care for early-onset disruptive behavior disorders (oppositional defiant disorder and conduct disorder), which frequently co-occur with attention deficit hyperactivity disorder, are well established, yet an ahistorical, program-specific lens tells little regarding how leaders, University of Oregon Medical School, shaped the common practice elements of contemporary evidence-based BPT. Accordingly, this review summarizes the formative work of Hanf, as well as the core elements, evolution, and extensions of her work, represented in Community Parent Education (COPE; (Cunningham et al. in J Child Psychol Psychiatry 36:1141–1159, 1995; Cunningham et al. in COPE, the community parent education program: large group community-based workshops for parents of 3- to 18-year-olds, COPE Works, Hamilton, 2009), Defiant Children (DC; (Barkley in Defiant children: a clinician’s manual for assessment and parent training, Guilford Press, New York, 1987; Barkley in Defiant children: a clinician’s manual for assessment and parent training, Guilford Press, New York, 2013), Helping the Noncompliant Child (HNC; Forehand and McMahon in Helping the noncompliant child: a clinician’s guide to parent training, Guilford Press, New York, 1981; McMahon and Forehand in Helping the noncompliant child: family-based treatment for oppositional behavior, 2nd ed., Guilford Press, New York, 2003), Parentchild interaction therapy (PCIT; Eyberg and Robinson in J Clin Child Adolesc Psychol 11:130–137, 1982. doi:10.1080/15374418209533076; Eyberg in Child Fam Behav Ther 10:33–46, 1988; Eyberg and Funderburk in Parent–child interaction therapy protocol, PCIT International, Gainesville, 2011), and the Incredible Years (IY; (Webster-Stratton in Behav Ther 12:634–642, 1981. doi:10.1016/S0005-7894(81)80135-9; Webster-Stratton in J Pediatr Psychol 7:279–294, 1982. doi:10.1093/jpepsy/7.3.279; Webster-Stratton in The incredible years: parents and children series. Leader’s guide: preschool version of BASIC (ages 3–6 years, The Incredible Years, Seattle, 2008). Our goal is not to provide an exhaustive review of the evidence base for the Hanf-Model programs, rather our intention is to provide a template of sorts from which agencies and clinicians can make informed choices about how and why they are using one program versus another, as well as how to make inform flexible use one program or combination of practice elements across programs, to best meet the needs of child clients and their families. Clinical implications and directions for future work are discussed.  相似文献

A dynamic touch paradigm in which participants judged the lengths of rods and pipes was used to test the D. M. Jacobs and C. F. Michaels (2007) theory of perceptual learning. The theory portrays perception as the exploitation of a locus on an information manifold and learning as continuous movement across that manifold to a new locus, as guided by information available in feedback. The information manifold was defined as a 1-dimensional space of inertial variables. To encourage maximal learning, a 2-step procedure was used in each of 2 experiments. Each step comprised a pretest to identify the starting locus on the information manifold, a practice phase in which feedback specifying the optimal locus was given, and a posttest in which the ending locus on the manifold was identified. In the 2nd step, a different feedback variable specified a different optimum. In both experiments, participants, who sometimes began at different loci, showed the predicted movement toward the optimum in each phase. Whereas previous applications of the theory posit the existence of information-for-learning without identifying a candidate variable, such a candidate is identified.  相似文献
