More evidence that less is better: Sub-optimal choice in dogs     

Rebecca J. Chase  David N. George 《Learning & behavior》2018,46(4):462-471

The less-is-better effect is a preference for the lesser of two alternatives sometimes observed when they are evaluated separately. For example, a dinner service of 24 intact pieces might be judged to be more valuable than a 40-piece dinner service containing nine broken pieces. Pattison and Zentall (Animal Cognition, 17: 1019-1022, 2014) reported similar sub-optimal choice behavior in dogs using a simultaneous choice procedure. Given a choice between a single high-value food item (cheese) or an equivalent high-value item plus a lower-value food item (carrot), their dogs chose the individual item. In a subsequent test, the dogs preferred two high-value items to a single high-value item, suggesting that avoidance of multiple items did not cause the sub-optimal choice behavior. In two experiments, we replicated Pattison and Zentall’s procedure while including additional controls. In Experiment 1, habituation of neophobia for multiple items was controlled for by intermixing the two types of test trial within a single experimental session. In Experiment 2, we controlled for avoidance of heterogeneous rewards by including test trials in which a choice was offered between the combination of items and a single low-value item. In both experiments we observed sub-optimal choice behavior which could not be explained by either of these putative mechanisms. Our results, as well as those of Pattison and Zentall, are consistent with the suggestion that dogs’ assessment of the total value of multiple items is based, at least partly, on their average quality.  相似文献   

Using performance methods to enhance students' reading fluency

The quasi-experimental study examined the effects of pairing Rock and Read with Readers Theater and only Rock and Read on second grade students' reading fluency scores. The 51 subjects were pre- and post-tested on five different reading fluency measures. A series of 3 × 2 repeated measures ANOVAs revealed statistically significant interaction effects on three of the five outcome measures: expression and volume, phrasing, and pace. The analysis of simple effects showed large mean difference effect sizes in both treatments.  相似文献

The Role of Sports as a Social Status Determinant for Children

Abstract

This study was designed to examine children's attitudes toward the role of sports in determining social status, as well as the activities in which children prefer to participate. A total of 227 boys and 251 girls in Grades 4, 5, and 6 completed a questionnaire to determine which criteria were most important in determining personal, female, and male popularity. Personal popularity was answered by the girls and boys according to “what would make you well liked by your classmates. “Female and male popularity was determined by asking both girls and boys to decide “what would make (girls, for female subjects, and boys, for male subjects) well liked by your classmates. “A comparison of results from the Buchanan, Blankenbaker, and Cotten (1976) investigation and the present study indicated that, in the last 15 years, appearance has become more important and academic achievement less important in determining personal popularity for girls. For boys, the comparison revealed that sports have become more important and academic achievement less important in determining personal popularity. Boys reported sports to be the most important determinant of personal and male popularity and appearance as the most important determinant of female popularity. Sports and appearance became more important for boys with each higher grade level Girls reported appearance to be the most important determinant of personal, male, and female popularity. For girls, appearance became more important with each higher grade level A comparison of results from the Buchanan et al. (1976) and the present study indicated that the activities in which girls and boys preferred to participate have changed. The importance of “making good grades” has decreased and the importance of “being popular” has increased.  相似文献
