Although most studies of perceptual learning in human participants have concentrated on the changes in perception assumed to be occurring, studies of nonhuman animals necessarily measure discrimination learning and generalization and remain agnostic on the question of whether changes in behavior reflect changes in perception. On the other hand, animal studies do make it easier to draw a distinction between supervised and unsupervised learning. Differential reinforcement will surely teach animals to attend to some features of a stimulus array rather than to others. But it is an open question as to whether such changes in attention underlie the enhanced discrimination seen after unreinforced exposure to such an array. I argue that most instances of unsupervised perceptual learning observed in animals (and at least some in human animals) are better explained by appeal to well-established principles and phenomena of associative learning theory: excitatory and inhibitory associations between stimulus elements, latent inhibition, and habituation.  相似文献

Relevance,Application, and the Development of an Unlikely Theory   总被引:1,自引:1,他引:0  
This paper advances the argument that motor learning research is not relevant to the needs and interests of motor skill teachers. The principal reason is that motor learning researchers in university departments of physical education have responded to calls for paradigmatic shifts that were intended for experimental psychologists, not necessarily for researchers from departments of physical education. As a result, motor learning researchers have concentrated their efforts on studying the mechanisms underlying motor performance rather than on devising and testing ways to improve motor performance. The body of knowledge produced by this approach has been based on experiments employing laboratory tasks and treatment conditions that lack fidelity to those appropriate or even possible in real-world teaching environments. Consequently, little knowledge has been produced that can be directly applied to the technical aspects of teaching. It also is argued that progress toward an applied thrust has been hindered because energies of the most capable researchers have been spent on attempts to develop a grand theory of motor skills, a theory that can never emerge until researchers attend to the essential preliminary task of defining motor skills.  相似文献

The notions of lifelong learning and a learning society have been an important policy driver in the European Union at both the Commission and national government levels for a number of years. Overall, these policies aim to promote the twin goals of competitiveness in international markets and social cohesion within the still-expanding borders of the Union itself. To date, however, the impact of this emphasis on lifelong learning has been relatively slight. This article argues that this is in part because the policy process in relation to the development of a learning society is based on a view of governance and power that is open to reasoned dispute, and is, therefore, bound to disappoint in relation to its espoused goals. It is suggested that, rather than implementation being the main ‘problem’ of policy, the policy context inevitably generates many recontextualizations and renegotiations of meanings according to the situations and the actors involved, thereby undermining the notion of ‘implementation’ as a technical-rational process. It is argued that the complex negotiations enacted at local level reveal and are fashioned by tensions between the membership resources available to actors. This emphasizes complexity, diversity, and difference in policy processes, bringing to the fore a communicative and distributed approach to policy rather than one that is technical and centralizing.  相似文献

A major priority for the post-apartheid government in South Africa is the provision of a universal quality education. This article examines quality in the context of education reform, attempts to conceptualise quality, and critically reviews both the discourse and practice of quality interventions in South Africa from the late 1980s to the present. It is argued that work on quality has been influenced by the modernising agenda, and that this has led to two differing research strands. It is also suggested that the work on quality has been affected by the way in which education change is viewed. Three arguments are made in relation to change: that change must be viewed as a process rather than an event; that positive mandated change at the policy and legislation level has not necessarily led to change at the school level; and that education change has emphasised structure and putting systems in place rather than pedagogy and the processes of teaching and learning. The paper concludes by identifying the gaps in policy and research on quality. It calls for more qualitative and empirical school and classroom research, and suggests strategic areas for quality enhancement at the school level.  相似文献

In Experiment 1, we used six procedures in a series of unsuccessful attempts to obtain relational learning using trial-unique pictorial stimuli in pigeons. The Experiment began by testing conventional (three-key) matching-to-sample (MTS) and nonmatching-to-sample (NMTS); in subsequent stages of the experiment we progressively incorporated features of techniques that do obtain relational learning in a single-key apparatus. In Experiment 2, we found that acquisition of NMTS using pictorial stimuli proceeded no more rapidly than acquisition of a conditional discrimination. Experiment 3 showed that acquisition of NMTS was more rapid than acquisition of MTS when plain colored stimuli were used, but not when pictorial stimuli were used. These three experiments suggest that pigeons do not recognize pictorial stimuli shown on different keys. In Experiment 4, between-key recognition was obtained with familiar but not with novel pictorial stimuli. It is argued that perceptual learning facilitates the detection of the between-key identity of complex stimuli, and that perceptual processes may underlie the difficulty in demonstrating relational learning in pigeons.  相似文献

Traditionally, perceptual learning in humans and classical conditioning in animals have been considered as two very different research areas, with separate problems, paradigms, and explanations. However, a number of themes common to these fields of research emerge when they are approached from the more general concept of representational learning. To demonstrate this, I present results of several learning experiments with human adults and infants, exploring how internal representations of complex unknown visual patterns might emerge in the brain. I provide evidence that this learning cannot be captured fully by any simple pairwise associative learning scheme, but rather by a probabilistic inference process called Bayesian model averaging, in which the brain is assumed to formulate the most likely chunking/grouping of its previous experience into independent representational units. Such a generative model attempts to represent the entire world of stimuli with optimal ability to generalize to likely scenes in the future. I review the evidence showing that a similar philosophy and generative scheme of representation has successfully described a wide range of experimental data in the domain of classical conditioning in animals. These convergent findings suggest that statistical theories of representational learning might help to link human perceptual learning and animal classical conditioning results into a coherent framework.  相似文献

Identifying social learning in wild populations is complicated by the relative lack of ability to conduct controlled experiments in natural habitats. Even in more controlled captive settings, tracking the innovation and spread of behavior among known individuals can be challenging, and these studies often suffer from a lack of ecological validity. In recent years, a host of new approaches have been undertaken to attempt to provide more quantitative control and empirical demonstration of social learning, both in the wild and in captive settings that more closely mimic natural contexts. Developmental approaches are being undertaken more regularly that allow us to study the ontogenetic trajectory of complex skills in a variety of taxa. Likewise, a spirited focus on the social context of social learning has emerged, and researchers have begun to meticulously analyze the influences of social systems and the characteristics of demonstrators and observers. Here, we provide a review of these studies and summarize the opportunities and constraints that exist when one attempts to study learning in social species. We suggest that although the study of social learning in nonhuman animals is becoming much more complex, addressing this complexity provides a fruitful model for understanding the evolution of human cultural behavior.  相似文献

God's beliefs versus mother's: the development of nonhuman agent concepts   总被引:1,自引:0,他引:1  
Little research exists on how children understand the actions of nonhuman agents. Researchers often assume that children overgeneralize and attribute human properties such as false beliefs to nonhuman agents. In this study, three experiments were conducted to test this assumption. The experiments used 24 children in New York (aged 2,11-6,11 years), 52 children in Michigan (aged 3,5-6,11 years), and a second group of 45 children in Michigan (3,4-8,5 years) from Christian backgrounds. In the first two experiments, children participated in false-belief tests in which they were asked about human and various nonhuman agents including animals and God. Experiment 3 consisted of a modified perspective-taking task, also including nonhuman agents. The results of the study suggest that children do not consistently use human agent concepts but instead can use different agent concepts for some nonhuman agents like God and special animals. Children are not bound to anthropomorphize, but they often do.  相似文献

The aim of this paper is to offer a timely theory of education that abstains as much as feasibly possible from ‘taking sides’ in current ideological disputes. It begins by presenting a basic definition demarcating the concept of ‘education’ from other processes of human learning and formation, yet in a way that allows circumventing various features that have been the source of literary debates. The paper then presents education’s bi-dimensional structure and connects this structure to Schwartz’s theory of universal values. To further explicate the merits of the theory, the paper presents four generic types of education and connects each of them to Schwartz’s value scale (SVS). It is argued that the conception of education offered may serve as a commonly shared framework for educational theorists and practitioners alike to think about and research education.  相似文献

Though there has been considerable research in recent years into the ways in which children’s performance in conservation experiments is affected by the context of interaction, this has so far lacked a coherent theoretical basis. In this article, concepts from communication theory are applied to the behaviour of experimenter and subject in the experimental situation. It is argued that the child behaves according to the «metacontract» of a teacher-pupil interaction, i.e. he or she expects to receive instruction. In the classical conservation experiment of Piaget, these expectations are thwarted, because the experimenter does not conform to the rules of a teacher-pupil relationship. Instead, the experimenter follows the rules of a different metacontract—that of examination. In experiments where conservation abilities are taught, and in group interactions where conserving children cooperate with non-conserving children, the participants do behave according to the same metacontract. But the value of these studies is reduced by the exclusive attention paid to the eventual achievements of the child, instead of the cognitive processes during the learning phase.  相似文献

This paper considers features of domestic and social life aboard sail training vessels, exploring the particular character of life at sea, and how these features contribute to the distinctive character of sail training experience as a context for learning. Methodologically, the study lies in the sociological tradition of ethnography, focusing on the actions of participants and on the meanings ascribed to participation. Learning that takes place as a consequence of the residential and communal living dimensions are claimed by proponents as key elements of the sail training experience, and this account seeks to illuminate such claims and to make comparison between the experiences of participants and the accounts of practitioners and advocates of sail training. Space, movement and privacy are considered, alongside the inescapability of the setting, and the impact of domestic and working routines. These features are shown to create conditions that should be understood as those of a ‘total institution’ aboard ships. It is argued that the claims in respect of learning arising from communal domestic life are generally borne out by the empirical evidence. Situated learning is considered as a framework for understanding the processes taking place, and it is argued that it is the institutional character of life aboard a sail training vessel that creates its particular power as a learning experience.  相似文献

In this paper, I consider a social movement for animal rights as a site of learning about a particular form of ethics. I use a multiliteracies framework, which emphasizes critical consumption and creation across a range of media forms, to consider how learning unfolds using a different kind of medium: the affective body. Activists in this study learned to read the signs of their embodied encounters with nonhuman animals as a privileged mode for understanding their ethical truth. Then they used other forms of digital mediation to produce and spread the feelings of being present with animals for others. I discuss social media memes and virtual reality as two examples. I employ the term “im-mediacy” to emphasize both the affects of feeling present and the sense-making involved in mediation and its ideologies. This approach considers affect and semiosis as mutually constitutive processes in learning. The findings also suggest the need to consider the affects produced in learning environments that bring bodies in proximity to one another, or that use technology to mediate feelings of proximity, as well as what I describe as embodied literacies for sensing the needs of others and responding with care.  相似文献

In Search of an East Asian Identity in Mathematics Education   总被引:3,自引:0,他引:3  
East Asian students have consistently outperformed their counterparts in Western countries in recent international studies of mathematics achievement. However, these countries do not seem to have an established theory of mathematics education, and their teaching has been criticized as traditional and old fashioned. In search of an East Asian identity in mathematics education, this paper discusses the features of the East Asian mathematics education and their underlying values in contrast to features and values in the West. These are presented in terms of six dichotomies,namely, product versus process; rote learning versus meaningful learning;studying hard versus pleasurable learning;extrinsic versus intrinsic motivations;whole class teaching versus individualized learning; and competence of teachers:subject matter versus pedagogy. It is argued that these features are based on deep-rooted cultural values and paradigms. A characterization of these features and an analysis of the underlying values are essential in this search for an East Asian identity in mathematics education. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

This paper is the first stage in a larger international comparative project, coordinated through the International Association of Counselling, on policy determinants in the education of counsellors. It arose in part out of an interest in the cultural determinants of what is taken as evidence. As a first stage for the project, a case study approach is used that asks what are the important features of the therapeutic learning experience provided by programmes in different countries, and how have these come about. The first example is a 4-year MSc programme in Counselling and Psychotherapy in the United Kingdom, with the focus on the intended therapeutic learning experience. It is argued that much of the emerging dominant training model of today is unbalanced, with too great an emphasis on CBT and short-term cost-effectiveness, rather than on the provision of a sound understanding based on learning from lived experience. There is concern at the extent to which depths of thinking and feeling are brushed aside, and with this a focus on the relationship and understanding of people’s experiences. The authors provide an analysis of their chosen training model through locating it historically in trends within European philosophy. The paper concludes by considering the appropriateness of Eurocentric approaches for other cultures.  相似文献

This article feeds into debate about the feasibility and usefulness of educational experiments by discussing methodological issues arising out of a study which sought causal links between teaching and learning of one aspect of French as a foreign language. The study involved two small‐scale experiments which tested a hypothesis regarding the learning of second language grammar within a particular theoretical, and its related pedagogical, framework (Input Processing and Processing Instruction respectively), and has been described in full elsewhere. The current article uses that example to suggest some circumstances (contextual, methodological and theoretical) within which educational experiments may be able to both test a learning theory and inform educational practice. It is argued that despite the complexities and limits of small‐scale educational experiments, an experimental design which combined a range of methods was able to generate new and useful (in a range of senses) substantive knowledge.  相似文献

Two experiments with rats tested independent predictions from cognitive theories of serial pattern learning. The animals learned to anticipate, as measured by running times in a straight alley, different quantities of food pellets organized into formally defined, five-element serial patterns. In Experiment 1, for some animals the patterns were all formally structured according to a monotonic “less than” relationship in which any quantity was always less than its predecessor. For others, no consistent formal rule was applied. Results of a transfer test with a new pattern showed positive transfer if the formal structure of the new pattern was identical to that used initially, but negative transfer if the new pattern was formally different. In Experiment 2, two groups learned the monotonic patterns 18-10-6-3-1 or 18-10-6-3-0 food pellets, while two others learned the nonmonotonic patterns 18-3-6-10-1 or 10-3-6-10-0 food pellets. We asked if the difference in value of the terminal element, 1 or 0 food pellets, would affect the facility with which the patterns were learned. The results showed that learning rate and the qualitative response to the elements of the monotonie and nonmonotonic patterns were independent of the value of the terminal element. Both experiments lend additional support to the utility of using cognitive models of human serial-pattern learning for an analysis of the sequential behavior of nonhuman animals.  相似文献

This article examines the differing learning styles found in western lecturers and Omani students in science lectures in the Sultanate of Oman. Oman is a country which modernized very recently, and students there were encountering western lecturers and lecturing methods for the first time. The western lecturers found the Omani approach to science, which they characterized as memorization deficient and wished to introduce a problem-solving approach. However, it is argued that some memorization occurs in all learning of science everywhere, that the Omani approach has its merits, and that a major problem in these lectures was the lack of knowledge of Omani and Arabic culture in the lecturers. It is argued that all learning takes place by matching new knowledge and methods with previous ones, and that to successfully lecture to the Omani students the lecturers would need to research further into ways in which their approach could have built on, rather than replaced entirely, the Omani approach. The article is based on interviews with the lecturers and extracts from the lectures, which were recorded and transcribed by the writer.  相似文献

Explicitly informing students about learning goals has been argued to foster intentional learning. This study tested three theoretical hypotheses regarding the facilitating effects of learning goals by investigating 72 students’ actual reading behaviour and cognitive processes (i.e., the use of learning goals). Participants studied a text presented on 15 separate computer screens with/without learning goals. In line with the three hypotheses, the analyses focused on three aspects: students’ interpretations of the learning goals, information selection processes and monitoring behaviour. Results indicated variability among students in their perceptions of the learning goals in terms of goal consistency and specificity. Students in the learning goal condition recorded more goal-relevant information in their notes. However, only few students deliberately used learning goals to monitor their goal-directed activities while studying the text. Analysis of students’ reading behaviour and cognitive processes suggests that the absence of significant performance differences between the conditions can be explained by referring to students’ actual use of learning goals.  相似文献
