Human delay discounting is usually studied with experimental protocols that use symbols to express delay and amount. In order to further understand discounting, we evaluated whether the absence of numbers to represent reward amounts affects discount rate in general, and whether the magnitude effect is generalized to nonsymbolic situations in particular. In Experiment 1, human participants were exposed to a delay‐discounting task in which rewards were presented using dots to represent monetary rewards (nonsymbolic); under this condition the magnitude effect did not occur. Nevertheless, the magnitude effect was observed when equivalent reward amounts were presented using numbers (symbolic). Moreover, in estimation tasks, magnitude increments produced underestimation of large amounts. In Experiment 2, participants were exposed only to the nonsymbolic discounting task and were required to estimate reward amounts in each trial. Consistent with Experiment 1, the absence of numbers representing reward amounts produced similar discount rates of small and large rewards. These results suggest that value of nonsymbolic rewards is a nonlinear function of amount and that value attribution depends on perceived difference between the immediate and the delayed nonsymbolic rewards.  相似文献

The authors explored the effects of a structured‐group career intervention among 280 Italian high school students. Hierarchical linear models indicated the intervention's effectiveness in increasing career decision‐making self‐efficacy and, consequently, career exploration, but not in decreasing career choice anxiety. In addition, partial confirmation was found for the moderating effects of participants' expectations and motivation to change on the relationship between career decision‐making self‐efficacy and career choice anxiety. The findings support the development of a systematic vocational guidance program in Italian schools.  相似文献

Companies and colleges often react strongly to allegations of sexual harassment, even firing men on first offenses, because of their fear of lawsuits. A review of sixty-two federal Courts of Appeals decisions in sexual harassment cases indicates that sexual harassment law is not as broad as suggested by these strong reactions.  相似文献

Hood recently reported that preschool children overgeneralized the prediction that falling objects travel in a straight line in spite of extensive counter‐evidence that the object had been deviated to a non‐aligned box by a tube. This behaviour was interpreted as a na?^ve theory of gravity resulting from an overgeneralization derived from experience of falling objects. The current study set out to test whether there was also a significant tendency for 2‐year‐olds to predict that objects travel in a straight line in the horizontal plane. This was achieved by comparing search for an invisibly displaced object moving either vertically or horizontally. The findings confirmed a gravity bias for falling events but did not reveal a similar tendency in the horizontal condition. In the horizontal task, children were as likely to search at an incorrect non‐aligned box as an aligned incorrect box. This supports the interpretation of a na?^ve gravity bias present from at least 2 years of age.  相似文献

This investigation documents the pattern of motor development of Brazilian infants over the first 6 months and compares the findings with a US norm. Infants were assessed once each month for the 6‐month period using the Bayley II Motor Scale, which represented the US norm for comparison. Participants monthly scores increased with age and were similar to the US profile. However, the Brazilian infants did exhibit mean scores significantly lower than their counterparts on tasks of sitting and grasping in the 3rd, 4th, and 5th month; at the 6th month, scores were comparable. Explanations for differences focus on possible cross‐cultural and maturational influences. Copyright © 2000 John Wiley & Sons, Ltd.  相似文献

Children and adolescents who experience a traumatic brain injury (TBI) typically have sensory, cognitive, behavioral, and functional skill challenges that must be addressed in acute and post-acute rehabilitation settings. This article describes a community-based school that combines educational, medical, nursing, family, residential-living, and psychological services in a comprehensive program of pediatric neurorehabilitation. The operational, administrative, and clinical features of these service components are presented. A critical aspect of the program is an emphasis on applied behavior analysis procedures for purposes of assessment, treatment formulation, and evaluation. Data are reviewed to demonstrate demographics, patterns of service delivery, and outcome. The school program represents an educational alternative for students with TBI who are discharged from acute-care settings and require comprehensive support services to facilitate their transition and re-entry to public school and community living. © 1998 John Wiley & Sons, Ltd.  相似文献

Interest in the well‐being of people exposed to long‐term violence and conflict has tended to focus on measurable effects of acute traumatic events, while attention to the pressures of their daily living context is relatively new. Using qualitative and quantitative data from a 2005 survey of all female family caretakers in 2 neighbouring Israeli‐occupied West Bank villages (n = 820), we explored the associations of demographic, health‐related and contextual factors with reported pressures and WHO‐5 well‐being index scores. The final model explained 17.8% of the variance with negative associations between health‐related factors (“back‐aches,” “stomach aches” “psychological illness in the family”) and family‐related factors (“male head of household aggressive”, “male head of household physically violent”) and the WHO‐5 well‐being index scores. We found positive associations between socio‐economic factors (“standard of living”; “number of rooms”) and village‐related factors (“residency in village A/B”) and the WHO‐5 well‐being index score. Exploring the daily living context of villages A and B illuminated how the impact of historical and political events differed, even in villages that are geographically close. The paper lends support to calls for including politics and history in research on well‐being in contexts of long‐term violence and conflict.  相似文献

This study assesses the retractions of scientific articles in engineering journals indexed on the Web of Science from 1945 to 2015. The data set was built based on documents containing the keywords retracted, retraction, withdrawal, or redress. We used database exploration techniques, including Structured Query Language and analysis of variance, for data analysis. We analyzed 238 retractions published by 117 journals. The most common reason for retraction was unethical research, and higher impact factors journals tended to publish more retractions. In conclusion, most of the analyzed retractions were the result of unethical research and were retracted by editors.  相似文献
