The theory of direct perception holds that perception is specific to properties of ambient energy arrays. This article explores a similar approach to perceptual and perceptual-motor learning: Change due to learning is portrayed as specific to properties of ambient energy arrays. This type of learning is labeled direct learning. It is argued that a theory of direct learning explains a wide range of phenomena in ecologically relevant and informationally rich situations as well as in simpler experimental situations. Previous experimental results are reanalyzed and reinterpreted from the perspective of direct learning. To achieve this, the notion of information space is introduced. In information spaces, points represent ambient energy variables, paths represent change due to learning, and vector fields represent information that guides learning. These concepts also allow the theory of direct learning to be connected to and to take advantage of the theory of ordinary differential equations. 相似文献

The purpose of this article is to describe Fortalezas Familiares (FF; Family Strengths), a community‐based prevention program designed to address relational family processes and promote well‐being among Latino families when a mother has depression. Although depression in Latina women is becoming increasingly recognized, risk and protective mechanisms associated with children's outcomes when a mother has depression are not well understood for Latino families. We begin by reviewing the literature on risk and protective psychosocial mechanisms by which maternal depression may affect Latino youth, using family systems theory and a developmental psychopathology framework with an emphasis on sociocultural factors shaping family processes. Next, we describe the theoretical basis and development of the FF program, a community‐based 12‐week intervention for Latina immigrant women with depression, other caregivers, and their children. Throughout this article, we use a case study to illustrate a Latina mother's vulnerability to depression and the family's response to the FF program. Recommendations for future research and practice include consideration of sociocultural processes in shaping both outcomes of Latino families and their response to interventions. 相似文献

Although recent studies suggest a strong association between short-term memory (STM) for serial order and lexical development, the precise mechanisms linking the two domains remain to be determined. This study explored the nature of these mechanisms via a microanalysis of performance on serial order STM and novel word learning tasks. In the experiment, 6- and 7-year-old children were administered tasks maximizing STM for either item or serial order information as well as paired-associate learning tasks involving the learning of novel words, visual symbols, or familiar word pair associations. Learning abilities for novel words were specifically predicted by serial order STM abilities. A measure estimating the precision of serial order coding predicted the rate of correct repetitions and the rate of phoneme migration errors during the novel word learning process. In line with recent theoretical accounts, these results suggest that serial order STM supports vocabulary development via ordered and detailed reactivation of the novel phonological sequences that characterize new words. 相似文献

Displacing an object with a hand-held rod provided a simple paradigm for studying tool use. The authors asked how reaching was affected by manipulations of rod properties. Adults held a rod (length = .10 to 1.5 m), with its tip in the air; walked toward an object on a table; chose a place to stop; and displaced the object with the rod's tip. In 3 experiments (Ns = 9, 22, and 17 participants), the authors manipulated rod length, mass, and mass distribution to determine whether and how geometric and dynamic properties affected the chosen distance and the posture. Both the chosen stopping distance and the postures were well accommodated to rod characteristics. Postural adaptations took place only in the arm, which was organized as a synergy. Predictably, rod length explained most of the variance, but small and reliable differences in both distance and posture depended on mass and mass distribution. The chosen distance anticipated not only rod length but also the upcoming posture needed to control the rod. 相似文献

The aim of the current study was to examine the relationship between motor coordination and visual working memory in children aged 5–11 years. Participants were 18 children with movement difficulty and 41 control children, assessed at baseline and following an 18-month time period. The McCarron Assessment of Neuromuscular Development provided a measure of motor skills and the CogState One-Back task was used to assess visual working memory. Multi-level mixed effects linear regressions were used to assess the relationship between fine motor skills, gross motor skills, and visual working memory. The results revealed that for children with movement difficulty, better fine motor skills at baseline significantly predicted greater One-Back accuracy and greater (i.e., faster) speed at 18-month follow-up. Conversely, fine motor skills at baseline did not predict One-Back accuracy and speed for control children. However, for both groups, greater One-Back accuracy at baseline predicted better fine and gross motor skills at follow-up. These findings have important implications for the assessment and treatment of children referred for motor difficulties and/or working memory difficulties. 相似文献

Disabled people frequently find themselves in situations where their quality of life and wellbeing is being measured or judged by others, whether in decisions about health care provision or assessments for social supports. Recent debates about wellbeing and how it might be assessed (through subjective and/or objective measures) have prompted a renewed focus on disabled people’s wellbeing because of its seemingly ‘anomalous’ nature; that is, whilst to external (objective) observers the wellbeing of disabled people appears poor, based on subjective assessments, people with disabilities report a good quality of life. In this paper, I examine an article by the philosopher Dan Moller in which he seeks to explain this ‘disability paradox’. Despite agreeing with his analysis that there is more to what people value than happiness, his explanation reflects some of the difficulties presented in philosophical accounts which seek to understand the lives of disabled people: this includes an analysis which fails to problematise definitions of wellbeing and who has the ‘voice’ to do the defining; which negates the multiple identities and subject positions that disabled people occupy; and which lacks recognition of the social contexts which mediate disabled people’s lives. I suggest that there is a need to incorporate disabled people’s voices into research which deepens our empirical knowledge about the relationship between impairment and wellbeing, including the social circumstances that shape disabled people’s agency. 相似文献

Abstract This study examines Israeli couples' presenting complaints about their relationship, their perceptions of one another's complaints and perceptual accuracy between actual and perceived complaints, using the Areas of Change Questionnaire (ACQ). Samples were obtained of both distressed and nondistressed couples. Each sample met stringent criteria for categorization as distressed and nondistressed. Normative data for both samples are examined and areas of similarities and differences are discussed. The instrument is found to discriminate distressed and nondistressed Israeli couples. Results are compared with a previous study of American distressed and nondistressed couples. The American finding that women desire more change in marriage is not replicated in the Israeli sample, nor the American finding that distress and stage in the life cycle are related. However, there is an indication in both samples that men, compared to women, perceive more requests for change. Men in both cultures also feel more change is asked of them than they themselves ask in return. 相似文献

Reading fluency has been identified as a key component in effective literacy instruction (National Reading Panel, 2000). Instruction in reading fluency has been shown to lead to improvements in reading achievement. Reading fluency instruction is most commonly associated with guided repeated oral reading instruction. In the present retrospective study we examine the effects of a computer-based silent reading fluency instructional system called Reading Plus (Taylor Associates, Winooski, Vermount, USA) on the reading comprehension and overall reading achievement of a large corpus of students in an urban school setting. Findings indicate that the program resulted in positive, substantial, and significant improvements in reading comprehension and overall reading achievement on a criterion referenced reading test for Grades 5, 6, 7, 8, and 9 and on a norm-referenced test of reading achievement for Grades 4, 5, 6, 7, 8 and 10. Moreover, mean gains made by students in the Reading Plus intervention were greater than mean gains for all students at the state and district level. The findings were generally positive for all subpopulations studied, including special education and regular education students. Qualitative reports from teachers who participated in the study were also supportive of the program. Implications for the study are explored for particular subgroups of students and for the role of fluency instruction with struggling adolescent readers. 相似文献

AbstractA troubling gap exists between the current state of history assessment and the knowledge and skills deemed essential for students to thrive in the 21st century. We propose a new assessment of historical thinking that represents a promising alignment with extant cognitive research, as well as with the practices that undergird the discipline. In this article, we discuss the design of the Assessment of Historical Analysis and Argumentation (AHAA), as well as the accompanying scoring rubric, and report findings from our administration of multiple forms of the exam with secondary students (N?=?618). Evidence indicates that the exam captured student historical thinking about documents and that the items prompted students to construct a cognitive representation of intertextual reasoning. Given the dearth of assessments that capture student historical thinking about documents and their understanding of content, we believe the AHAA has the potential to be an important instructional resource. 相似文献
