It is generally agreed that concept learning involves the abstraction of some general representation or schema. Just what is abstracted, however, and how it is used in the classification of sets of stimuli in the natural world or in the laboratory, remain outstanding questions. In this paper a hypothesis involving contingency abstraction is described as a possible solution to these questions. An experiment which manipulated measured contingency in a concept-learning task, and which offered empirical support for the hypothesis, is reported. The advantages of a contingency-abstraction theory of concept learning are briefly discussed.  相似文献

Infants are uniquely vulnerable to maternal depression's noxious effects, but few longitudinal studies have tried to identify discrete postnatal trajectories of maternal depressive symptoms (MDS) beginning in infancy. This study extends evidence of heterogeneous change in postnatal MDS by examining their cross-contextual antecedents in infancy and their consequences for children's early behavior problems and language skills in late toddlerhood. A community sample of mother–child dyads (N = 235, 72% Caucasian) was assessed when children were 7, 15, and 33 months old. Mothers reported their socioeconomic status (SES), social support, marital relationship quality, family dysfunction, parenting stress, and infants’ functional regulatory problems at 7 months postpartum, and children's internalizing and externalizing symptoms at 33 months. Children completed a receptive vocabulary assessment at 33 months in the lab. Latent class growth analysis identified three postnatal MDS trajectory classes that fit the data best: low-decreasing, moderate, and increasing. Psychosocial measures at seven months postpartum primarily predicted membership to these postnatal trajectory classes, which subsequently differed in children's internalizing, externalizing, and receptive vocabulary in late toddlerhood, controlling for family SES and functional regulatory problems in infancy. We discuss salient antecedents and consequences of postnatal depression for mothers and their offspring.  相似文献

This study tested the hypothesis that individuals can proactively manage their own energetic, affective, and cognitive resources in order to be creative at work. Building on proactivity and creativity literatures, we propose a theoretical model in which employees who proactively manage their vitality are more engaged in their work and show improved creative performance. We also tested the boundary conditions of this process. Participants were Dutch employees from various occupations who filled out a background questionnaire and five weekly surveys. The results of multilevel modelling analyses offered support for our model. Weekly proactive vitality management was positively related to changes in weekly creativity through changes in weekly work engagement. As predicted, learning goal orientation strengthened and performance goal orientation weakened the links between proactive vitality management and engagement, and between engagement and creativity. We discuss the theoretical contributions, and indicate how these findings can be used in daily working life.  相似文献

The author considers the concept of enactment as a ubiquitous event that is best seen as part of a sequence in the process of understanding a patient. As such, enactments are not unusual or special save as they are often subject to disavowal or to being singled out by the analyst as especially subject to scrutiny. Once recognized, enactments need to be interpreted: not so much in terms of their unconscious origins, but more with regard to the need to include them in the analytic dialogue.  相似文献

This paper explores the therapeutic value of considering psychoanalytic diagnoses as co-constructions, and emphasizes two interrelated points: First, there are distinctions between medical, psychiatric, and psychoanalytic diagnoses, and similarly, a distinction may be drawn between diagnoses as nouns and the activity of diagnosing. Second, the author stresses that psychoanalytic diagnoses are theory bound. Various competing theories facilitate or interfere with the maintenance of an optimal analytic attitude. Some theories facilitate an analyst's urge to engage in the activity of diagnosing, which may reflect a destructive countertransference enactment. Analytic data in support of these premises is presented and discussed.  相似文献

The Collaborative Multimodal Treatment Study of Children with Attention Deficit Hyperactivity Disorder (ADHD), the MTA, is the first multisite, cooperative agreement treatment study of children, and the largest psychiatric/psychological treatment trial ever conducted by the National Institute of Mental Health. It examines the effectiveness of Medication vs. Psychosocial treatment vs. their combination for treatment of ADHD and compares these experimental arms to each other and to routine community care. In a parallel group design, 579 (male and female) ADHD children, aged 7–9 years, 11 months, were randomly assigned to one of the four experimental arms, and then received 14 months of prescribed treatment (or community care) with periodic reassessments. After delineating the theoretical and empirical rationales for Psychosocial treatment of ADHD, we describe the MTA's Psychosocial Treatment strategy applied to all children in two of the four experimental arms (Psychosocial treatment alone; Combined treatment). Psychosocial treatment consisted of three major components: a Parent Training component, a two-part School Intervention component, and a child treatment component anchored in an intensive Summer Treatment Program. Components were selected based on evidence of treatment efficacy and because they address comprehensive symptom targets, settings, comorbidities, and functional domains. We delineate key conceptual and logistical issues faced by clinical researchers in design and implementation of Psychosocial research with examples of how these issues were addressed in the MTA study.Deceased  相似文献
