The interaction of conditioned taste aversions and schedule-induced polydipsia: Availability of alternative behaviors     

Anthony L. Riley  David B. Peele  Kathy D. Richard  Paul J. Kulkosky 《Learning & behavior》1981,9(2):287-290

Animals poisoned following exposure to saccharin subsequently avoided the schedule-induced consumption of saccharin. While this suppression was transient for subjects who had access only to the saccharin solution during the free-food presentations, recovery of schedule-induced saccharin consumption was significantly retarded for subjects who had concurrent access to saccharin and a running wheel. It has been suggested that the transient suppression of schedule-induced polydipsia by conditioned taste aversions results from the pellet-induced tendency to drink within the schedule-induced polydipsia procedure. That access to the running wheel reduces schedule-induced polydipsia in general and prolongs the suppression of schedule-induced polydipsia by taste aversions supports this view.  相似文献   

College and university planning in an era of contraction   总被引：1，自引：0，他引：1  

Anthony W. Morgan 《Higher Education》1982,11(5):553-566

Drawing from published case studies of U.S. institutions and from case studies conducted in the U.K., the author assesses the causes and characteristics of decline among institutions of higher education and the various types of institutional planning responses. Planning under conditions of instability and decline is held to be significantly different from planning under conditions of growth in that the politics of planning are more intensive and highly defensive. Changes in the standards for organizational consensus in planning under decline are also discussed. The problems and advantages inherent in developing strategic contingency plans as opposed to developing strategic planning policies are noted.The author concludes with a summarization of the contrasting planning styles characteristic of U.S. institutions, U.K. polytechnics and U.K. universities, noting that the model and success of recent University Grants Committee selective cuts among many institutions is more likely to be transferred to the polytechnic sector than across the Atlantic to U.S. institutions.  相似文献   

A Person-Centered Approach to Students' Evaluations of Perceived Fear Appeals and Their Association With Engagement     

Laura J. Nicholson  David W. Putwain  Ghada Nakhla  Benjamin Porter  Anthony Liversidge  Monika Reece 《Journal of Experimental Education》2019,87(1):139-160

A person-centered approach was employed to investigate how students' evaluation of perceived teacher utility value messages, i.e., fear appeals, as a threat and as a challenge, combined within individuals and how these combinations related to student engagement. Two studies were conducted with students in their final two years of secondary education. Empirically distinct clusters emerged at two time points in the academic year. Evaluating the message in the fear appeal at a higher level of challenge than threat was beneficial. Unexpectedly, high threat was associated with high engagement, as long as high challenge was also present, however, this combination was also related to high emotional disaffection. Moderate threat combined with moderate challenge had the most detrimental relationship with student engagement. Educational interventions should aim to increase the likelihood of a challenge evaluation.  相似文献

Remembering Activities Performed Versus Imagined: A Comparison of Children with Mental Retardation and Children with Normal Intelligence     

Kenneth G. Jens  Betty N. Gordon  Anthony J. Shaddock 《International Journal of Disability, Development & Education》1990,37(3):201-213

CHILDREN with mental retardation and children with normal intelligence were asked to perform a series of tasks or to only imagine performing them. They were then asked to remember which tasks had been performed and which had been imagined at an immediate interview and after an eight week delay. There were no overall differences between the two groups in the number of correct responses. However, all children gave more correct responses to specific probes than to open‐ended probes and remembered activities performed better than those imagined. Performance was more accurate for both groups at the immediate interview than at the delayed interview. Responses to questions about activities neither performed nor imagined were good for both groups of children to the initial questions but decreased significantly in response to a follow‐up probe. Accuracy of responses to these misleading questions decreased over the eight week delay.  相似文献   

A Resource for Eliciting Student Alternative Conceptions: Examining the Adaptability of a Concept Inventory for Natural Selection at the Secondary School Level     

Margaret M. Lucero  Anthony J. Petrosino 《Research in Science Education》2017,47(4):705-730

The Conceptual Inventory of Natural Selection (CINS) is an example of a research-based instrument that assesses conceptual understanding in an area that contains well-documented alternative conceptions. Much of the CINS’s use and original validation has been relegated to undergraduate settings, but the information learned from student responses on the CINS can also potentially be a useful resource for teachers at the secondary level. Because of its structure, the CINS can have a role in eliciting alternative conceptions and induce deeper conceptual understanding by having student ideas leveraged during instruction. In a first step toward this goal, the present study further investigated the CINS’s internal properties by having it administered to a group (n?=?339) of students among four different biology teachers at a predominantly Latino, economically disadvantaged high school. In addition, incidences of the concept inventory’s use among the teachers’ practices were collected for support of its adaptability at the secondary level. Despite the teachers’ initial enthusiasm for the CINS’s use as an assessment tool in the present study, results from a principal components analysis demonstrate inconsistencies between the original and present validations. Results also reveal how the teachers think CINS items may be revised for future use among secondary student populations.  相似文献   

Testing Literacy Educational Software to Develop Design Guidelines for Children with Autism     

Marian Tuedor  Fabia Franco  Anthony White  Serengul Smith  Ray Adams 《International Journal of Disability, Development & Education》2019,66(1):19-35

Multimedia computer programmes have been found to facilitate learning in children with Autistic Spectrum Disorders (ASD). However, the effectiveness of these resources is limited due to poor design or a lack of consideration of the ASD cognitive profile, particularly at the lower functioning end of the spectrum. This article attempts to tackle the problem of the lack of design guidelines, with the aim of facilitating the development of effective educational programmes for children with severe ASD. The case study reported here evaluated two literacy educational computer programmes, by observing five low-functioning children with ASD, compared to five neurotypical children (control cases). The two types of reading-support software contrasted in the study presented different characteristics. The children’s data analysed here concern observations of child–software interactive sessions based on video recordings and coded for attention deployment to each programme, including motivation and engagement indicators.  相似文献   

Conditioning of the nictitating membrane response of the rabbit (Oryctolagus cuniculus) as a function of length and degree of variation of intertrial interval     

W. Ronald Salafia  Frederick W. Mis  W. Scott Terry  Robert S. Bartosiak  Anthony P. Daston 《Learning & behavior》1973,1(2):109-115

The study involved three experiments. The first, a parametric investigation of nictitating membrane conditioning with eight constant intertrial intervals (ITIs) between 5 and 120 sec, orthogonal to interstimulus intervals (ISIs) of 250 and 750 msec plus three temporal conditioning control groups, revealed that performance improved rapidly with increasing ITI but stabilized at relatively low ITI values. At 750-msec ISI, a decrement in performance was found at 60-sec ITI. Experiment II, using constant ITIs of 45–75 sec in 5-sec steps, at 750-msec ISI confirmed the trend toward a performance decrement around 60 sec, although the trend was weak and highly variable. Experiment III evaluated the differences in performance between constant and variable ITI, using three ITI values and three conditions of variation at each value. Findings were discussed in terms of differences in conditioning resulting from both length and degree of variation of ITI and some subtle effects which may emerge only when constant ITIs are used.  相似文献   

Interactive Television (ITV) Instructor Behaviors: Implications of Frequency and Importance     

Barbara K. McKenzie  James E. Witte  Anthony J. Guarino  Maria Martinez Witte 《Innovative Higher Education》2002,27(1):65-73

Two hundred students majoring in education responded to the Validation of Effective Behaviors of Distance Instructors Inventory (McKenzie, Kirby, & Mims, 1997). The 41 items measured two dimensions: frequency and importance of effective behaviors in delivering distance instruction. A two-way within-subjects ANOVA was conducted. Of the 41 items, 14 were rated higher in importance than in frequency. The 14 items were then analyzed using Principal Component Analysis with Varimax rotation, which yielded two factors: Effective Learning Methods and Student Guidance. This study suggests that the behaviors of Interactive Television (ITV) instructors may be lacking in these two important factors.  相似文献
