Using computer-delivered natural speech to assist in the teaching of reading     

Johan Davidson  David Coles  Peter Noyes  Colin Terrell 《British journal of educational technology : journal of the Council for Educational Technology》1991,22(2):110-118

The findings of a pilot study designed to evaluate a computer system developed to assist in the teaching of reading to beginners are presented. The system uses digitised speech and the content is based upon a reading scheme already in use in the schools. Twenty children, ten in the intervention group and ten in the control group, in two schools were involved over a four-week period. Subjects were tested on a standardised reading test, a list of the 30 most frequently occurring words in written English, and on words from the published scheme. The experimental group improved their scores significantly more than the control group only on the standardised reading test. The results suggest the system can be helpful and that its effect goes beyond the words being practised.  相似文献   

Empathy Is Associated With Dynamic Change in Prefrontal Brain Electrical Activity During Positive Emotion in Children   总被引：1，自引：0，他引：1  

Sharee N. Light  James A. Coan  Carolyn Zahn-Waxler  Corrina Frye  H. Hill Goldsmith  Richard J. Davidson 《Child development》2009,80(4):1210-1231

Empathy is the combined ability to interpret the emotional states of others and experience resultant, related emotions. The relation between prefrontal electroencephalographic asymmetry and emotion in children is well known. The association between positive emotion (assessed via parent report), empathy (measured via observation), and second-by-second brain electrical activity (recorded during a pleasurable task) was investigated using a sample of one hundred twenty-eight 6- to 10-year-old children. Contentment related to increasing left frontopolar activation ( p  < .05). Empathic concern and positive empathy related to increasing right frontopolar activation ( p s < .05). A second form of positive empathy related to increasing left dorsolateral activation ( p  < .05). This suggests that positive affect and (negative and positive) empathy both relate to changes in prefrontal activity during a pleasurable task.  相似文献   

Effect of a randomised 12-week resistance training programme on muscular strength,cross-sectional area and muscle quality in women having undergone Roux-en-Y gastric bypass

The purpose of this study was to examine the effect of a 12-week resistance training programme on fat-free mass (FFM), muscle cross-sectional area, muscular strength and muscle quality in women who underwent Roux-en-Y gastric bypass surgery. Participants were 16 women (mean age = 44.9 ± 10.2 years) from bariatric surgical groups who were randomly assigned into either a control or an intervention group. Air displacement plethysmography measured FFM and magnetic resonance imaging measured quadriceps muscle cross-sectional area and whole thigh muscle cross-sectional area. Muscular strength and quality was assessed using an estimated 1-Repetition Maximum assessment. All measurements were collected twice, at baseline and at a 12-week follow-up. There were significantly greater improvements in leg press strength (mean differences = 55.4%, P < 0.001, Cohen’s d = 2.4), leg extension strength (mean differences = 18.0%, P = 0.014, Cohen’s d = 0.86) and leg press muscle quality (mean differences = 54.5%, P < 0.001, Cohen’s d = 1.9) in the intervention group compared to the control group following the resistance training programme. The resistance training intervention significantly improved muscular strength and quality; however, it did not illicit changes in FFM or muscle cross-sectional area in women who underwent Roux-en-Y gastric bypass surgery.  相似文献   

Transfer of facilitation in the rat     

T. L. Davidson  Robert A. Rescorla 《Learning & behavior》1986,14(4):380-386

In two experiments, rats solved two concurrent discrimination problems in which one stimulus (i.e., a facilitator) signaled the reinforcement of another stimulus (i.e., a target). Then a transfer test assessed the capacity of facilitators trained in one problem to promote responding to targets trained in the other. Experiment 1 found that a facilitator promoted as much responding to such a transfer target as to the target with which it was originally trained. Transfer was not obtained with a pseudofacilitator that was uninformative, in training, about the reinforcement of its target. Experiment 2 manipulated the stimulus modality of the targets and facilitators. Its results indicated that transfer performance was not due to generalization between training and transfer targets or facilitators. These results parallel those from comparable autoshaping paradigms with pigeons, and they agree with the view that facilitators promote responding by lowering the threshold for activation of the US representation.  相似文献   

eResources in Academic Libraries: A Look Ahead     

Karen S. Davidson  Tim Collins 《期刊图书馆员》2013,64(1):59-62

Tim Collins, President and Founder, EBSCO Publishing, presented “eResources in Academic Libraries: A Look Ahead” at the eResource & Emerging Technologies Summit held at Mississippi State University Libraries on August 3, 2012. Collins presented EBSCO's strategy for creating the single search box and the philosophy behind their Discovery Service. He provided information on the different types of content providers and the search capabilities of their Discovery Service. Collins also presented information regarding eBooks on EBSCOhost and what they have done since acquiring NetLibrary.  相似文献   

Desk Bound No More: Reference Services at a New Research University Library     

Sara Davidson  Susan Mikkelsen 《The Reference Librarian》2013,54(4):346-355

The authors discuss a newly established academic library at the University of California, Merced, as a model for reference service that foregoes a desk staffed with reference librarians. The library provides innovative, quality reference services for its users by using well-trained staff at a library services desk and employing new technologies for asynchronous communication and instruction.  相似文献   

Hope,optimism and loneliness among first-year college students with learning disabilities: a brief longitudinal study     

Eyal Rosenstreich  David B. Feldman  Oranit B. Davidson  Etai Maza 《欧洲特需教育杂志》2013,28(3):338-350

The goals of the study were to examine personal resources and social distress during the first month in college among students with learning disabilities (LD) and to compare their experiences with non-LD peer. The sample consisted of 335 first-year undergraduate students falling into two groups: 85 students with LD and 250 non-LD students. Questionnaires assessed hope, dispositional optimism and loneliness. We hypothesised that, after participation in a single-session hope intervention workshop, the hope and optimism levels of both students with LD and without LD would increase, while their loneliness would decrease. However, after a month of facing the academic and social demands of their new college environment, we expected that the hope and optimism scores of students with LD would be lower than their peers without LD and that their loneliness scores would be higher. As hypothesised, both groups reported enhanced hope and optimism, as well as lower loneliness, immediately after the workshop. However, students with LD – but not their peers – returned to baseline levels of hope and loneliness after a month. Loneliness after a month predicted lower hope, after controlling predictors from the beginning of the year.  相似文献   

Intelligence Recreated     

Janet E. Davidson 《教育心理学家》2013,48(3-4):337-354

Many of us are frustrated with the overuse of intelligence tests. But intelligence tests have become so entrenched in our society that it is hard to imagine how they realistically could be replaced. Schools would be without a well-established screening device, and intelligence research would be without an external measure of validity. But what if we started over and imagined thinking about intelligence without the benefit (some would say hindrance) of Binet? What would theories and tests of intelligence look like? The articles in this special issue address this topic; here, I discuss the articles. The discussion is divided into three sections. The first section deals with definitional issues: How can intelligence be operationally defined, and can a single definition capture cognitive abilities of individuals at all ages? The second section briefly summarizes and evaluates each of the seven theories: How intelligent are these theories of intelligence? The final section focuses on the implications of the theories and theory-based tests reported in this issue: How can future research and educational practices benefit from the views presented here?  相似文献
