It seems obvious that various feelings (various kinds of affectivity) are memorized, forgotten, and recollected to various degrees. Some of them are forgotten. Some of those forgotten can be recollected, while others are lost forever. For example, short and long-lasting feelings and shallow and deep feelings are memorized and remembered in different ways. In this paper I analyse from a conceptual point of view several categories of memory-of-feelings and offer a comprehensive map of them. In the end, the richness of categories in the realm of memory is interpreted as a proof of the intricacy of affectivity.  相似文献

From an eligible population of 9,943 casino employees, 6,067 volunteered to participate in this study. Of this sample, 1,176 provided data at 3 observation points approximately 12 months apart. Using the South Oaks Gambling Screen (SOGS; H. R. Lesieur & S. B. Blume, 1987) and the CAGE (J. A. Ewing, 1984) questionnaire, the authors prospectively examined the prevalence and patterns of alcohol and gambling problems among those employees. Among the casino employees with gambling and drinking problems, a segment displayed the capacity to diminish those problems even when the difficulties had reached disordered levels. The authors also examined the comorbidity of gambling and drinking as well as the relationships among changes in SOGS scores and CAGE scores and changes in demographic and biological variables. The women were more likely to decrease their problem-drinking scores, but not their gambling scores, when compared with the men. In addition, 2 key variables (i.e., disabling depression and dissatisfaction with one's personal life) emerged as predictors of transitions to healthier levels of disordered gambling. The authors cautiously suggest, in light of the results taken together, that more fluctuation is associated with gambling and drinking problems than previously thought and that the conventional wisdom about disordered gambling as "always progressive" needs reconsideration.  相似文献

To test the hypothesis that lower social status is associated with more smiling, the authors used newspaper photographs and their associated news stories as the basis for scoring the smiling and relative social status of the 2 individuals in each photograph. Independent raters judged smiling and 5 dimensions of relative status for 496 individuals in 248 newspaper photographs. There was no relation between status and smiling, although status and smiling were both related to other variables such as gender, age, and story valence. These findings add to a growing body of evidence that there is no generalized relation between smiling and status.  相似文献
