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   

Behavioral momentum in academics: Using embedded high‐p sequences to increase academic productivity     

David L. Lee  Phillip J. Belfiore  Mary Catherine Scheeler  Youjia Hua  Rachel Smith 《Psychology in the schools》2004,41(7):789-801

The use of high‐probability (high‐p) request sequences has enjoyed support in the applied behavioral literature as a method to increase compliance. Based on the theory of behavioral momentum, high‐probability sequences increase the rate of responding, and subsequent rate of reinforcement, within a response class. This increase in density of reinforcement results in increased responding for the response class as a whole. Early research in this area had focused mainly on compliance issues for individuals with developmental disabilities. However, more recently the utility of high‐p sequences has been examined within the context of academics. The purpose of these two experiments was to examine the use of high‐p sequences with two academic tasks—letter‐writing and mathematics problem completion. The results of these studies suggest that high‐p sequences can be used to increase academic productivity. Moreover, the addition of experimenter‐delivered reinforcers to existing high‐p sequences enhances overall behavioral persistence. Theoretical and applied implications of persistence and behavioral momentum are discussed. © 2004 Wiley Periodicals, Inc. Psychol Schs 41: 789–801, 2004.  相似文献   

Genetic and environmental influences in adolescent peer socialization: evidence from two genetically sensitive designs     

Iervolino AC  Pike A  Manke B  Reiss D  Hetherington EM  Plomin R 《Child development》2002,73(1):162-174

Harris argues that peer relationships are the chief determinants of personality development. Harris's thesis makes the behavioral genetic investigation of peer groups particularly timely. The present study examined genetic and environmental contribution to self-reported peer-group characteristics in two samples of adolescent siblings: 180 adoptive and nonadoptive sibling pairs from the Colorado Adoption Project, and 386 sibling pairs from the Nonshared Environment and Adolescent Development Study. Substantial genetic influence emerged for college orientation, with the remaining variance accounted for by nonshared environment. For delinquency, however, the majority of the variance was explained by nonshared environment. Although genetic influence was implicated for peer popularity in twin analyses, genetic factors were not important in explaining individual differences in nontwin siblings. These results suggest that although some dimensions of peers are somewhat mediated by genetic factors, nonshared environmental influence is substantial.  相似文献   

Autoshaping of initial feeding and drinking reactions in newly hatched chicks     

Guy Woodruff  M. David Starr 《Learning & behavior》1978,6(3):265-272

Newly hatched chicks were force-fed food and water throughout rearing, and food, water, or sand reinforcers during exposure to an omission-training procedure. The chicks were thus prevented from performing approach and contact responses to the reinforcer at any time in their lives. Nevertheless, the subjects displayed approach and species-specific feeding or drinking reactions directed toward an illuminated key paired with food or water, but not with sand. Illumination of a key either uncorrelated or negatively correlated with food or water did not engender appreciable responding. Feeding and drinking reactions were topographically distinct, determined by the type of reinforcer, but were not elicited by the reinforcer. These findings support a “learned release” view of autoshaping, according to which phylogenetically preorganized behavior patterns are triggered by distal stimuli paired with biologically significant proximal stimulation, and suggest a close relationship between autoshaping and primitive instances of visual object recognition.  相似文献   

Trends in computer applications in science assessment     

David D. Kumar  Stanley L. Helgeson 《Journal of Science Education and Technology》1995,4(1):29-36

Seven computer applications to science assessment are reviewed. Conventional test administration includes record keeping, grading, and managing test banks. Multiple-choice testing involves forced selection of an answer from a menu, whereas constructed-response testing involves options for students to present their answers within a set standard deviation. Adaptive testing attempts to individualize the test to minimize the number of items and time needed to assess a student's knowledge. Figurai response testing assesses science proficiency in pictorial or graphic mode and requires the student to construct a mental image rather than selecting a response from a multiple choice menu. Simulations have been found useful for performance assessment on a large-scale basis in part because they make it possible to independently specify different aspects of a real experiment. An emerging approach to performance assessment is solution pathway analysis, which permits the analysis of the steps a student takes in solving a problem. Virtually all computer-based testing systems improve the quality and efficiency of record keeping and data analysis.  相似文献
