We compared a research-based, manualized intervention called Helping the Noncompliant Child (HNC; McMahon and Forehand 2003) to treatment as usual (TAU) for 194 children, 3–9?years old, with disruptive behavior disorders in a community clinic. The two interventions did not produce different outcomes or levels of parent satisfaction. However, almost three times as many parents in the HNC condition stated they ended therapy because their goals had been met, and almost three times as many parents in TAU stated they terminated because of practical obstacles. Number of sessions was related to outcome in the HNC condition but not in TAU.  相似文献

This report evaluates whether a rat releasing a trapped rat from a restraint tube is better explained as due to its empathic motivation or to the pursuit of social contact. In the first condition, each of six rats chose in an E maze between entering an empty goal box versus entering a goal box where its entrance caused a rat trapped in a restraint tube to be released. Rats preferred the goal box with the trapped rat over the empty goal box. In the second condition, these rats chose between releasing a restraint‐tube‐trapped rat in one goal box and another rat in the second goal box that was not locked into its restraint tube. Rats showed no preference between alternatives. In the third condition, rats chose between a goal box containing a rat with an open restraint tube and an empty goal box. Rats preferred the rat with the open restraint tube over the empty goal box. These results support attributing the response of releasing a rat from a restraint tube to the reinforcing power of social contact rather than interpreting this response as empathically motivated.  相似文献

This paper uses chronic beryllium disease as a case study to explore some of the challenges for decision-making and some of the problems for obtaining meaningful informed consent when the interpretation of screening results is complicated by their probabilistic nature and is clouded by empirical uncertainty. Although avoidance of further beryllium exposure might seem prudent for any individual whose test results suggest heightened disease risk, we will argue that such a clinical precautionary approach is likely to be a mistake. Instead, advice on the interpretation of screening results must focus not on risk per se, but on avoidable risk, and must be carefully tailored to the individual. These points are of importance for individual decision-making, for informed consent, and for occupational health.

In this brief review of some of my research on reading disability, I argue that a child’s development into literacy has two major ontogenetic roots, one involving early informal literacy socialization and one related to phonological awareness. Although failure in reading acquisition might be a question of cultural deprivation, the dynamic interaction between genetic dispositions and environment must be acknowledged, especially in a society providing rich sources of print exposure. The crucial transition in literacy development involves a step from implicit to explicit control of the phonemic units of language. When the cipher of the alphabetic system is understood the child is equipped with a powerful instrument for self teaching. A primary source of reading disability is then related to problems of segmenting the speech stream into phonemic units. The poor functioning of the phonological module seems to be a circumscribed deficit not related to general cognitive ability. The causal and reciprocal relationship between phonological awareness and learning to read has been demonstrated in my research over 20 years. Some of these studies are briefly reviewed in this article. The preventive and remedial implications of the findings are rather obvious.  相似文献

Recent work on perceptual learning shows that listeners' phonemic representations dynamically adjust to reflect the speech they hear (Norris, McQueen, & Cutler, 2003). We investigate how the perceptual system makes such adjustments, and what (if anything) causes the representations to return to their pre-perceptual learning settings. Listeners are exposed to a speaker whose pronunciation of a particular sound (either /s/ or /integral/) is ambiguous (e.g., halfway between /s/ and /integral/). After exposure, participants are tested for perceptual learning on two continua that range from /s/ to /integral/, one in the Same voice they heard during exposure, and one in a Different voice. To assess how representations revert to their prior settings, half of Experiment 1's participants were tested immediately after exposure; the other half performed a 25-min silent intervening task. The perceptual learning effect was actually larger after such a delay, indicating that simply allowing time to pass does not cause learning to fade. The remaining experiments investigate different ways that the system might unlearn a person's pronunciations: listeners hear the Same or a Different speaker for 25 min with either: no relevant (i.e., 'good') /s/ or /integral/ input (Experiment 2), one of the relevant inputs (Experiment 3), or both relevant inputs (Experiment 4). The results support a view of phonemic representations as dynamic and flexible, and suggest that they interact with both higher- (e.g., lexical) and lower-level (e.g., acoustic) information in important ways.  相似文献

During the past 20 years, states have increasingly expanded the lists of individuals who are obligated to report their suspicions of child abuse and neglect. These legal requirements are juxtaposed with ethical considerations in research and professional practice. The ethical issues include the obligation to maintain both confidentiality of information provided by human participants and the safety and protection of these participants. This article reviews the types of state child abuse reporting statutes and outlines the categories of mandated reporters. I develop a model of how individual researchers should approach deciding whether they are mandated reporters of child abuse and neglect.  相似文献

A new grouping principle, uniform connectedness (UC), has been posited to be a basic organizer of visual pattern information, one that takes precedence over other, more classic grouping principles (Palmer & Rock, 1994), but its ontogenetic origins have not previously been investigated. We examined whether 3- to 4-month-olds and 6- to 7-month-olds utilize UC to organize static two-dimensional displays. Infants habituated to uniformly connected patterns exhibited a novelty preference for disconnected element patterns, whereas those without any habituation failed to exhibit a preference. The results indicate that infants are sensitive to UC as a cue for perceptual organization. Prior studies indicate that some Gestalt principles (e.g., common movement) are functional during the first half year of life, but that other principles (e.g., form similarity) are less readily available. The present finding showing that young infants are sensitive to UC points to the foundational nature of this cue and adds to an emerging body of evidence indicating that at least some of the mechanisms believed to produce perceptual organization in adults are already operational in the first months of life. nt]mis|This research was supported by grants from the National Science Foundation (BCS 0224240) and the National Institute of Child Health and Human Development (HD042451).  相似文献

In his influential paper, ‘Why Was the Logic of Discovery Abandoned?’, Laudan contends that there has been no philosophical rationale for a logic of discovery since the emergence of consequentialism in the 19th century. It is the purpose of this paper to show that consequentialism does not involve the rejection of all types of logic of discovery. Laudan goes too far in his interpretation of the historical shift from generativism to consequentialism, and his claim that the context of pursuit belongs to neither discovery nor justification is based on narrow interpretations of the contexts of discovery and justification. As a result, Laudan draws unwarranted conclusions concerning both the early and contemporary defenders of a logic of discovery. A methodological logic of discovery—which involves self‐corrective methods of hypothesis generation that promote the long‐term goals of science and which require consequential support for justification—is a type of logic of discovery that survives the shift to consequentialism.  相似文献

In response to Zimmerman's commentary, ‘Is collaboration a viable target for family therapists?’ we explore more conventional perspectives of therapeutic collaboration featured in the family therapy literature, including Zimmerman's commentary. In particular, we critique essentialist and universal formulations that portray the client–therapist relationship to be inherently unequal as inconsistent and limiting. We conclude by addressing what appear to be some misunderstandings in Zimmerman's commentary and clarify what we see as differences between his ideas and our stance on collaboration and power in family therapy.  相似文献

For about five decades the phrase “sanctity-of-life“ has been part of the Anglo-American biomedical ethical discussion related to abortion and end-of-life questions. Nevertheless, the concept’s origin and meaning are unclear. Much controversy is based on the mistaken assumption that the concept denotes the absolute value of human life and thus dictates a strict prohibition on euthanasia and physician-assisted suicide. In this paper, I offer an analysis of the religious and philosophical history of the idea of “sanctity-of-life.” Drawing on biblical texts and interpretation as well as Kant’s secularization of the concept, I argue that “sanctity” has been misunderstood as an ontological feature of biological human life, and instead locate the idea within the historical virtue-ethical tradition, which understands sanctification as a personal achievement through one’s own actions.  相似文献

If we consider the field of argumentation studies, we notice that many approaches consider argumentation in a pragmatic manner and define it as a verbal activity oriented towards the realization of a goal. The idea that subtends—in an explicit or implicit way—most of these approaches is that argumentation fundamentally aims to produce an effect upon an addressee, and that this effect consists in a change of attitude with respect to a viewpoint: argumentation theories inevitably confront the issue of persuasion. In this article, I defend, on the contrary, the hypothesis that it is not necessary to have recourse to the notion of persuasion, nor even to speak of an attempt to provoke a change of attitude in the addressee, in order to develop a general definition of argumentation. It seems to me that there are serious reasons to uncouple, insofar as a definition is concerned, argumentation and persuasion. I will look to identify these reasons, to formulate them and to evaluate their strength. In the same vein as recent works by Christian Plantin and Marc Angenot, I will try to contribute to the development of a non-persuasive conception of argumentation. Such a conception bases the definition of argumentation on the pragmatic aims of “justification” and “positioning”, as well as on the articulation of a discourse and a counter-discourse. I argue that such a conception might offer a better empirical adequacy than those that link, insofar as a definition, the argumentative activity and the persuasive aim.  相似文献

Extinction of operantly conditioned responses, which provides a measure of the ability to adapt to changes in the reinforcement value of stimuli, has been linked to orbitofrontal cortex (OFC) in human and non-human animals. This article examines the feasibility of using extinction as a measure of the development of OFC function in preschool-age children. If extinction serves as a measure of OFC function, resistance to extinction should decrease during this age range. In Part 1, we review the literature on extinction as related to OFC, and summarize what is known regarding age-related changes in extinction in young children. In Part 2, we report results of a study assessing extinction in children between 3 and 6 years of age. Results revealed age-related increases in responding during extinction, with girls (particularly, 6-year-old girls) exhibiting stronger resistance to extinction. Some relations were found with temperament and normative compulsive-like behavior. The findings of this study question the utility of extinction of operant responding as a measure of OFC function in young children.  相似文献

G. P. Bingham, R. C. Schmidt, and L. D. Rosenblum (1989) found that, by hefting objects of different sizes and weights, people could choose the optimal weight in each size for throwing to a maximum distance. In Experiment 1, the authors replicated this result. G. P. Bingham et al. hypothesized that hefting is a smart mechanism that allows objects to be perceived in the context of throwing dynamics. This hypothesis entails 2 assumptions. First, hefting by hand is required for information about throwing by hand. The authors tested and confirmed this in Experiments 2 and 3. Second, optimal objects are determined by the dynamics of throwing. In Experiment 4, the authors tested this by measuring throwing release angles and using them with mean thrown distances from Experiment 1 and object sizes and weights to simulate projectile motion and recover release velocities. The results showed that only weight, not size, affects throwing. This failed to provide evidence supporting the particular smart mechanism hypothesis of G. P. Bingham et al. Because the affordance relation is determined in part by the dynamics of projectile motion, the results imply that the affordance is learned from knowledge of results of throwing.  相似文献

This paper has two objectives. The first is to formulate a critique of present-day cognitive linguistics (CL) concerning the inner workings of the cognitive system during language use, and the second is to put forward an alternative account that is inspired by the phenomenology of Merleau-Ponty. Due to its third-person methodology, CL views language use essentially as a problem-solving activity, as coping with two subproblems: the problem of minimum and maximum, which consists in selecting the appropriate expression out of an unlimited multitude of possibilities, and the problem of the underdetermination of signification. This approach presupposes a notion of an isolated subject and a representationalist view of perception. We defend an alternative view of man's relation to the world in which intersubjectivity is constitutive of embodied subjectivity and which exchanges the representationalist view of perception for a direct nonrepresentationalism. We describe the ensuing view of linguistic action as intra- and interpersonal “all-at-onceness.” This approach dismisses the two subproblems CL implicitly identifies as constitutive of language use. The first is countered by rethinking what it means to be a situated speaking subject and results in the concept of “style.” The second is tackled by opposing the concept of “overdetermination” to CL's notion of underdetermination.  相似文献
