The effects of differing type and magnitude of reward on the contrafreeloading phenomenon in rats     

Lynn C. Robertson  Suzanne C. Anderson 《Learning & behavior》1975,3(4):325-328

This investigation was made to determine the effects of the magnitude of reward on contrafreeloading, using food or water as reward. Two quantities were selected for each level of reward quality—a 20-mg-pellet food reward, a 45-mg-pellet food reward, a .01-cc water reward, and a .1-cc water reward. Seven days of training were followed by three test sessions. There was a significantly higher percent of contrafreeloding demonstrated with food as reward than with water and higher number of barpresses with small reward than with large. It was argued that a more appropriate measure should include reference to performance during training. In this approach, contrafreeloading with food and water were virtually the same.  相似文献   

Inconsistent response patterns and the prediction of child maltreatment     

J S Milner  K R Robertson 《Child abuse & neglect》1989,13(1):59-64

Inconsistent response patterns have been used with other measures to screen for child maltreatment. To date the inconsistency (IC) scale, a validity scale on the Child Abuse Potential (CAP) Inventory, has not been used as a screening criterion for physical child abuse. The present study examined the responses of 89 physical child abusers and 108 comparison subjects to determine if the CAP Inventory IC scale has any utility in the screening for physical child abuse. While results indicated the CAP Inventory IC scale scores were significantly higher for the physical child abuse group, a series of discriminant analyses indicated that the IC scale did not account for any meaningful variance after variance related to child abuse factors was removed. Further, the results indicated that dependence on the IC scale alone for physical child abuse screening purposes could be expected to produce excessive false positive and false negative classifications.  相似文献   

The ambiguous embrace: twenty years of IT (ICT) in UK primary schools     

John Robertson 《British journal of educational technology : journal of the Council for Educational Technology》2002,33(4):403-409

School inspection reports, at the end of the 20th Century, in both Scottish and English primary schools, clearly identify the use of ICT as the weakest aspect of professional practice. On this evidence, despite initial certainty of political purpose and considerable optimism regarding its effects on teaching and learning, ICT remains, after twenty years, a marginal force in the education of 5–12 year–olds. Though numerous research studies in the 1980's and 1990's seemed to have identified the conditions for the effective transfer of ICT into primary schools and repeated governmental initiatives invested heavily in both infrastructure and training, teachers have not embraced ICT within their core practice. This paper suggests that the adoption of exclusively rational, perhaps hyper–rational, methodologies, by researchers working in the mainstream of schools and teacher education institutions has resulted in a failure to understand the complex cultural, psychological and political characteristics of schools. Alternative avenues for research are proposed.  相似文献   

Development of sex-trait stereotypes among young children in the United Staes, England, and Ireland     

D L Best  J E Williams  J M Cloud  S W Davis  L S Robertson  J R Edwards  H Giles  J Fowles 《Child development》1977,48(4):1375-1384

The Sex Stereotype Measure II (SSM II), a 32-item revision of the Williams, Bennett, and Best Sex Stereotype Measure, was developed to assess children's knowledge of conventional, sex-trait stereotypes defined by American university students. The procedure employed brief stories and human figure silhouettes which were individually administered to 5- and 8-year-old children in the United States, England, and Ireland and group administered to 11-year-olds in the United States. In the United States, knowledge of sex-trait stereotypes was found to develop in a linear fashion between the ages of 5 and 11, with more male traits than female traits being known at each age level. Cross-nationally, there was a high degree of similarity in the nature of the sex stereotypes being learned by the children in the 3 countries, although the rate of learning appeared slower among the Irish children. In all countries there was a clear progression in sex-stereotype learning from age 5 to age 8. English boys had greater knowledge of stereotypes than English girls, but this was not true in Ireland and the United States. Generally, knowledge of male stereotype traits appeared to develop earlier while knowledge of the female traits increased more rapidly between ages 5 and 8. The similarity in sex-stereotype learning in the 3 countries is discussed, and studies in progress in other countries of greater cultural diversity are noted.  相似文献   

An account of practice: employing drawings and stories to enable reflective learning     

Jane Robertson  Heidi le Sueur  Nicky Terblanche 《Action Learning: Research and Practice》2019,16(1):77-86

Facilitating reflection for personal growth in a business context requires careful thought and planning. As a learning process, Business-Driven Action Learning (BDAL) has two points of focus. It aims to firstly identify and make recommendations regarding a business challenge, whist secondly facilitating potentially significant individual personal learning and growth. The research reported in this account of practice focused on personal learning by exploring the potential for individuals to experience transformative learning during a BDAL process. During the research I used a number of methods including hand-drawn images and in-depth interviews to enable the writing of interpretive stories. Findings revealed that participants found reflection during and after the BDAL beneficial. They gained insights into what they learnt, what changed since the BDAL experience and also what they still need to focus on. The findings have practical implications for the action learning facilitator of BDAL during management development programmes. One of the ways action learning facilitators can initiate the reflection process of new participants is to share the experience of previous participants. ‘Sandy’s interpretive story’, contained in this article, is such an example and includes hand-drawn images of her learning journey. I argue that the use of interpretative stories helps new participants understand programme challenges and stimulates their individual learning journey.  相似文献   

An Evaluation of Schoolwide Early Language and Literacy (SWELL) in Six Disadvantaged Schools     

Yola Center  Louella Freeman  Gregory Robertson 《International Journal of Disability, Development & Education》1998,45(2):143-172

A within‐school evaluation of Schoolwide Early Language and Literacy (SWELL) was undertaken in six disadvantaged schools in NSW in 1995 and 1996 using a sample of Kindergarten students in each school before (control group) and after (experimental group) the implementation of SWELL. As many control and experimental students as could be accessed were tested on four different early literacy measures when they were mid‐way through Year 1. Assessment at the end of the Kindergarten year and mid‐way through Year 1 indicated that experimental students significantly outperformed their control counterparts on tests measuring pseudoword decoding and reading connected text at the end of Kindergarten, and on tests measuring pseudoword decoding, reading connected text, invented spelling, and a standardised reading measure mid‐way through Year 1.  相似文献

ABSTRACT

Differences and similarities between table tennis and other racquet sports exist, but are not well documented in the literature, in spite of the relevance for talent identification. In this study we aimed at identifying the key characteristics of table tennis in comparison with tennis and badminton based upon a survey in coaches. A total of 177 licensed coaches from all across the world and with diverse professional backgrounds completed a survey on anthropometric measures, physical performance, and motor coordination skills. On a scale from 1 to 10, coaches indicated to what extent a talent characteristic was important for their sport. MANOVA identified key differences as well as similarities between all three racquet sports and a subsequent discriminant analysis allocated coaches correctly for table tennis, tennis, and badminton 81.01%, 55.6%, and 71.4% respectively. Our results show that table tennis and other racquet sport coaches are well aware of differences between the racquet sports and also the importance and value of testing and assortment of skill components. These findings can assist coaches in future talent orientation and transfer in racquet sports.  相似文献
