The effect of deservingness in invidious situations on the intensity of schadenfreude: a developmental study / El efecto del merecimiento sobre la intensidad de schadenfreude en situaciones de envidia: un estudio evolutivo     

Laura Quintanilla  Patricia Recio 《Infancia y Aprendizaje》2019,42(2):374-412

Objectives: envy is a negative social emotion that stems from a social comparison. This study explores the effect of deservingness on the intensity of schadenfreude (pleasure in another’s misfortune) in situations of invidious comparison. Method: the participants, 181 children between the ages of three and 10, were asked to describe what an envious character felt when the character (s/he) envied had lost an (deserved or undeserved) advantage. They were also asked to explain their answers. Results: the findings showed that schadenfreude was more intense when the lost advantage was undeserved than deserved only in young children. The difference between conditions decreased with age. The children’s explanations of schadenfreude were based on the damage to the envied person, whereas the responses of pity were justified by the misfortune and equitable ending (no one wins) of the story. Conclusions: the discussion addresses some of the possible factors, such as the acquisition of display rules, deservingness and perception of equality, that contribute to children’s understanding of emotions such as envy and schadenfreude.  相似文献

The pits and falls of graphical presentation     

Sandro Sperandei 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2014,24(3):311-320

Graphics are powerful tools to communicate research results and to gain information from data. However, researchers should be careful when deciding which data to plot and the type of graphic to use, as well as other details. The consequence of bad decisions in these features varies from making research results unclear to distortions of these results, through the creation of “chartjunk” with useless information. This paper is not another tutorial about “good graphics” and “bad graphics”. Instead, it presents guidelines for graphic presentation of research results and some uncommon, but useful examples to communicate basic and complex data types, especially multivariate model results, which are commonly presented only by tables. By the end, there are no answers here, just ideas meant to inspire others on how to create their own graphics.  相似文献
