The aim of this study was to construct a model of the elicitation of schadenfreude through vengeance, envy, and trait anger. Japanese undergraduates (239 men, 284 women) completed questionnaires assessing dispositional vengeance, trait anger, and empathy. Then, participants read two scenarios: one about a target person's success and one about his or her misfortune. After reading the first scenario, the participants were asked to rate their envy toward the target person, then their feelings of schadenfreude after the second. A Japanese version of the Vengeance Scale was developed, and its construct validity and test-retest reliability were confirmed. Structural equation modeling was applied to examine how dispositional vengeance, trait anger, and envy were related to schadenfreude. The results indicated that envy and dispositional vengeance were significantly related to scores on the schadenfreude scale, with no gender effect, whereas vengeance was associated with envy only for women.
This study focused on the differences between two, subtypes of envy known as "benign envy" and "malicious envy" as personality traits, and examined the effects of these traits on academic achievement. Two hundred fifty-one university students participated in the study. Both benign envy and malicious envy were found to be independent as also found in a previous study by Lange & Crusius (2015), and a high criterion-related validity was revealed by an association with characteristic variables such as dispositional envy and self-esteem. The students with higher levels of benign envy were found to set goals higher, and as a result achieved higher levels of academic performance. In contrast, no such effect was found for malicious envy. The importance of focusing more attention on the positive aspects of the emotion of envy is discussed.
The purpose of this study was to develop the Japanese version of the Dispositional Greed Scale (J-DGS), and to examine its reliability and validity. The participants in this study were Japanese university students (N = 856). The principal component analysis indicated that the J-DGS had a unidimensional structure and adequate internal consistency. There were positive associations between the J-DGS and envy, psychological entitlement, materialism, impulsive buying behavior, extravagance, and neuroticism. Conversely, J-DGS scores were negatively correlated with self-control, self-esteem, life satisfaction, and agreeableness. These results, which are consistent with previous studies, confirmed the concurrent validity of the J-DGS.
The threshold levels of taste perception on the right and left side of the tip, root of tongue and soft palate in 60 healthy volunteers were measured by means of an electrogustometry test and a filter-paper disk taste test to confirm the following hypotheses: (1) the threshold on the tip of the tongue was lower than those of the root of the tongue and soft palate, (2) there was a different threshold level between sweet, salty, sour and bitter tastes on the tip of the tongue, (3) some personal properties influenced the person's threshold. Measured threshold levels were compared between these six locations with multiple comparisons. Factors influencing the threshold level on the tip of the tongue, thereafter, were investigated using multivariate logistic regression models. Those factors included sex, age, serological, psychological and behavioral factors. As a result, the thresholds levels on the tip of the tongue were significantly lower than the root of the tongue and soft palate. The thresholds for sweet and bitter taste on the tip of the tongue were also lower than those for salty and sour taste. Increase of age, male, serological increase of zinc and usual alcohol drinking were identified as factors of increase for several thresholds, and increase of anxiety was identified as a factor of decrease for two thresholds of four tastes (sweet, salty, sour and bitter) on the tip of the tongue in the logistic regression models. Increase of depression, mouth breathing, habitual tonus of the tongue and smoking did not appear to be influential factors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
