This study examined influences on the rate and quality of parent participation in the Fast Track Program, a multi-system, longitudinal preventive intervention for children who are at risk for conduct problems. A theoretical model of the relations among family coordinator characteristics, parent characteristics, the therapeutic engagement between family coordinator and parent, and rate and quality of parent participation was the basis for this study. Family coordinators are the Fast Track program personnel who conduct group-based parent-training sessions and home visits. Participants in this study included 12 family coordinators (42% were African American, 58% European American) and 87parents (55% were African American, 45% European American). The level of therapeutic engagement between the parent and the family coordinator was positively associated with the rate of parent attendance at group training sessions. The extent of family coordinator-parent racial and socioeconomic similarity and the extent of the family coordinator's relevant life experiences were highly associated with the level of therapeutic engagement. The quality, but not the rate, of participation was lower for African American parents. Implications of these findings for preventive intervention with this population are discussed. 相似文献

Two experiments were designed to assess Korsakoff patients' ability to encode verbal information on the basis of its physical, nominal and semantic properties. The first investigation employed Wickens' release from proactive interference (PI) technique; a procedure that allows an assessment of a subject's ability to encode verbal information on the basis of its semantic properties. It was discovered that on tasks involving only a rudimentary verbal analysis, such as the ability to discriminate letters from numbers, the Korsakoff patients demonstrated a normal release from PI. However, on tasks that required a more sophisticated level of semantic encoding, such as those based on taxonomic class inclusion, the patients failed to show release from PI. The second investigation employed Posner's reaction time technique which assesses a subject's ability to encode the physical and nominal properties of simple verbal materials (letters). The results of this study showed that Korsakoff patients are impaired on even these rudimentary encoding tasks, which led to the proposal that Korsakoff patients' semantic encoding deficit might stem from an initial impairment in the speed at which physical and nominal properties of verbal information are analyzed. 相似文献

A previous attempt to improve amnesic Korsakoff patients' retention of individual words resulted in only moderate improvement and, then, only under restricted conditions. It appeared that this occurred because the patients “forget” the instructed analysis of the word as well as the word itself. Consequently, the two experiments reported here sought to provide feature (Experiment 1) or associated (Experiment 2) cues at both input and output. In this manner relatively good performance was obtained, but only when semantic cues were “strongly” associated to the target words. Implications for an encoding specificity interpretation are drawn from these results. 相似文献

Existing models that integrate emotion and cognition generally do not fully specify why cognition needs emotion and conversely why emotion needs cognition. In this paper, we present a unified computational model that combines an abstract cognitive theory of behavior control (PEACTIDM) and a detailed theory of emotion (based on an appraisal theory), integrated in a theory of cognitive architecture (Soar). The theory of cognitive control specifies a set of required computational functions and their abstract inputs and outputs, while the appraisal theory specifies in more detail the nature of these inputs and outputs and an ontology for their representation. We argue that there is a surprising functional symbiosis between these two independently motivated theories that leads to a deeper theoretical integration than has been previously obtained in other computational treatments of cognition and emotion. We use an implemented model in Soar to test the feasibility of the resulting integrated theory, and explore its implications and predictive power in several task domains. 相似文献

In this paper, we examine the motivations for research on cognitive architectures and review some candidates that have been explored in the literature. After this, we consider the capabilities that a cognitive architecture should support, some properties that it should exhibit related to representation, organization, performance, and learning, and some criteria for evaluating such architectures at the systems level. In closing, we discuss some open issues that should drive future research in this important area. 相似文献

This essay examines how Gregory of Nyssa sees the Solomonic books of Scripture (Proverbs, Ecclesiastes, Song of Songs) train desire to long for God. The philosophical exercises contained in Proverbs and Ecclesiastes prepare the soul for the supreme training contained in the Song of Songs. The purpose of the Song of Songs is to lead the soul to union with God. The Trinitarian strategy of the philosophy contained in the Song of Songs exposes the soul to paradox and oxymoron, through which the soul is schooled to release its noetic–erotic grasp of concepts and is thus led to apophatic union with God. 相似文献

Classic cognitive theory conceptualizes executive functions as involving multiple specific domains, including initiation,
inhibition, working memory, flexibility, planning, and vigilance. Lesion and neuroimaging experiments over the past two decades
have suggested that both common and unique processes contribute to executive functions during higher cognition. It has been
suggested that a superordinate fronto–cingulo–parietal network supporting cognitive control may also underlie a range of distinct
executive functions. To test this hypothesis in the largest sample to date, we used quantitative meta-analytic methods to
analyze 193 functional neuroimaging studies of 2,832 healthy individuals, ages 18–60, in which performance on executive function
measures was contrasted with an active control condition. A common pattern of activation was observed in the prefrontal, dorsal
anterior cingulate, and parietal cortices across executive function domains, supporting the idea that executive functions
are supported by a superordinate cognitive control network. However, domain-specific analyses showed some variation in the
recruitment of anterior prefrontal cortex, anterior and midcingulate regions, and unique subcortical regions such as the basal
ganglia and cerebellum. These results are consistent with the existence of a superordinate cognitive control network in the
brain, involving dorsolateral prefrontal, anterior cingulate, and parietal cortices, that supports a broad range of executive
functions. 相似文献
