Concept learning by pigeons: Matching-to-sample with trial-unique video picture stimuli     

Anthony A. Wright  Robert G. Cook  Jacquelyne J. Rivera  Stephen F. Sands  Juan D. Delius 《Learning & behavior》1988,16(4):436-444

Pigeons were trained to match-to-sample with several new methodologies: a large number of stimuli, computer-drawn color picture stimuli, responses monitored by a computer touch screen, stimuli presented horizontally from the floor, and grain reinforcement delivered onto the picture stimuli. Following acquisition, matching-to-sample concept learning was assessed by transfer to novel stimuli on the first exposure to pairs of novel stimuli. One group (trial-unique), trained with 152 different pictures presented once daily, showed excellent transfer (80% correct). Transfer and baseline performances were equivalent, indicating that the matching-to-sample concept had been learned. A second group (2-stimulus), trained with only two different pictures, showed no evidence of transfer. These results are discussed in terms of the effect of numbers of exemplars on previous failures to find concept learning in pigeons, and the implications of the positive finding from this experiment on abstract concept learning and evolutionary cognitive development.  相似文献   

Agonistic democracy and passionate professional development in teacher-leaders     

L. Hammersley-Fletcher  M. Clarke  V. McManus 《Cambridge Journal of Education》2018,48(5):591-606

Politicians and policy-makers in education routinely proclaim the centrality of schools and teachers in sustaining and consolidating democracy and democratic society. This article offers an account of teachers engaged in research in their schools and classrooms, with peers and students, so as to highlight the democratic potential of this engagement. In order to do so, it draws on an agonistic account of democracy that is distinct from more familiar liberal or procedural versions. Such an account is characterised by an emphasis on the values of constitutive pluralism, robust contestation and enduring tragedy, where the latter entails recognition of the ineliminable nature of (political) conflict and the inevitability of loss in human life. The teachers involved in this research demonstrated capacities which, it is argued, reflect an agonistic democratic ethos, including: developing the confidence to assume intellectual leadership by asking questions and eliciting and engaging plural perspectives in relation to these questions; engagement in the cut and thrust of research without the expectation of finding any final or perfect solutions; and an acceptance of difference and disagreement as constitutive and constructive elements in rethinking areas of policy and practice. Developing and encouraging these capacities, it is argued, is important in an increasingly authoritarian policy context that threatens the vital links between democracy and education highlighted by Dewey a century ago.  相似文献

Recruiting the graduate voice: informing higher education initiatives to underpin an emerging,veterinary paraprofession in Australia     

Patricia Clarke  Joerg Henning  Glen Coleman  Daniel Schull 《Journal of Vocational Education & Training》2019,71(1):126-152

In Australia, the inception of veterinary technology, as a higher education discipline underpinning an emerging, mid-tier paraveterinary field, reflected global trends for more highly educated veterinary paraprofessionals to meet changing societal demands. In this study, veterinary technology graduates were surveyed about their experiences in the workforce and reflections on their education. Seeking feedback on how well a new programme has prepared graduates for the workforce is a useful quality assurance tool. Clinical veterinary practice was the primary employment sector with the majority of respondents in full-time employment. Career advancement, professional recognition and salaries were identified as key career challenges. The important roles of the veterinary and veterinary nursing professions, the university, government and graduates in the development of this mid-tier, veterinary paraprofession were elucidated. Graduates’ feedback on criteria that underpinned ‘work-readiness’ revealed seven key domains: communication skills, research skills, knowledge, critical thinking/problem-solving, employability, practical skills and professionalism. Veterinary nursing skills, work placement, practice management and production animal health were flagged as areas for curricular improvement. This study illuminated facilitators and barriers critical to establishing a mid-tier veterinary paraprofession, bridging the divide between the vocational and higher education sectors in Australia.

Incentive learning and the motivational control of instrumental performance by thirst     

Matias Lopez  Bernard Balleine  Anthony Dickinson 《Learning & behavior》1992,20(4):322-328

The role of incentive learning in instrumental performance following a shift in the degree of water deprivation was analyzed in three experiments. In Experiments 1A and IB, rats trained to perform an instrumental action reinforced with either sucrose or maltodextrin solutions when in a high-deprivation state were subsequently shifted to a low-deprivation state and tested in extinction. This within-state shift in water deprivation reduced instrumental performance only when the animals had been exposed to the reinforcer in the low-deprivation state prior to instrumental training. In Experiment 2, a concurrent training procedure was used to assess whether the change in the value of the reinforcer brought about by preexposurewas mediated by the contingency between the instrumental action and the reinforcer. Preexposure to the reinforcer under the low-deprivation state produced a selective reduction of the performance of the action upon which it was contingent during training when testing was conducted in extinction following a shift from the high- to the low-deprivation state. These experiments provide evidence that animals have to learn about the incentive value of a reinforcer in a particular motivational state through exposure to the reinforcer in that state.  相似文献   

Auditorysame/different concept learning by monkeys     

Anthony A. Wright  Melissa R. Shyan  Masako Jitsumori 《Learning & behavior》1990,18(3):287-294

Two rhesus monkeys learned the auditory abstract concept ofsame/different. They were trained with 38 different environmental and natural sounds, which were arranged in different combinations as training progressed. Upon transfer to 138 different novel stimuli, they performed as well (78.8% correct) on the first exposure to the novel stimuli as they did (77.3%) with their training stimuli. The comparatively large set of training sounds, contact with the sound source, and a special fading procedure are thought to have contributed to the monkeys’ being able to learn this concept. Implications for species’ similarities/differences in cognitive processing are discussed.  相似文献

Mapping teacher status and career-long professional learning: the Place Model     

Linda Clarke 《Discourse: Studies in the Cultural Politics of Education》2018,39(1):69-83

This paper engages with key contemporary debates about teaching and teacher education through proposing an innovative, interdisciplinary model, the Place Model, which uses two senses of ‘place’ to provide comparative lenses for a timely, a-priori examination of the place of the teacher: place in the humanistic geography tradition as a process – a cumulative, career-long professional learning journey – and, also, place in the sociological sense of teacher status. This article considers a range of international literature before speculatively ‘populating’ the model with a range of examples in a way which raises important questions about conceptions of teachers across the globe, and provides an alternative and original vision of the profession.  相似文献
