Data from 70 classes and 1829 students over a period of 15 years were analyzed. Grade and attendance differences were analyzed for five different seating configurations: by row, by column, the front of the room versus the back of the room, the center of the room versus the perimeter of the room, and the middle of the room versus the sides of the room. Results utilizing numeric percentage grades and attendance percentages indicated students sitting in the more central parts of the class had higher percentage grades and attended classes more frequently than those students sitting in the less central parts of the class. Women attended class more frequently than men, yet there were no sex differences on grades.  相似文献

Purpose  

Unrealistic optimism is all around us, and it is a well-documented psychological phenomenon. The purpose of this study is to take a critical approach of the main research done in the area and to analyze the important impact that it has in many economic and managerial contexts. We also analyze current trends in terms of entrepreneurship by policy makers.  相似文献

It is well known that emotions participate in the regulation of social behaviors and that the emotion displayed by a conspecific influences the behavior of other animals. In its simplest form, empathy can be characterized as the capacity to be affected by and/or share the emotional state of another. However, to date, relatively little is known about the mechanisms by which animals that are not in direct danger share emotions. In the present study, we used a model of between-subject transfer of fear to characterize the social interaction during which fear is transmitted, as well as the behavioral effects of socially transmitted fear. We found that (1) during social interaction with a recently fear-conditioned partner, observers and demonstrators exhibit social exploratory behaviors rather than aggressive behaviors; (2) learning and memory in a shock-motivated shuttle avoidance task are facilitated in rats that underwent a social interaction with a partner that had been fear conditioned; and (3) a brief social interaction with a recently fear-conditioned partner immediately before fear conditioning increases conditioned freezing measured on the next day. The observed effects were not due to a stress-induced increase in pain sensitivity or analgesia. Collectively, these data suggest that a brief social interaction with a cage mate that has undergone an aversive learning experience promotes aversive learning in an otherwise naïve animal. We argue that socially transferred fear is an adaptation that promotes defensive behavior to potentially dangerous situations in the environment.Human empathy can be defined as the ability to experience and share the thoughts and feelings of others (de Waal 2008). Obviously, this is a complex social phenomenon that, until recently, has received much attention from philosophers and psychologists rather than neuroscientists (Decety and Lamm 2006). However, in its simplest form, empathy can be characterized as the capacity to be affected by and/or share the emotional state of another (de Waal 2008). Tuning one''s emotional state to that of another increases the probability of similar behavior, which thereby allows rapid adaptation to environmental challenges (Hatfield et al. 1994). This social adaptation may be particularly important for emotions that signal a potential danger, such as fear. Although one can learn about potentially harmful stimuli by directly experiencing an aversive event, observation or interaction with a conspecific in danger and/or in pain may also provide information about threats in the environment. There is a vast literature on learning about direct danger (Maren 2001) as well as sharing emotions through observation (see, e.g., Church 1959; Langford et al. 2006; Olsson and Phelps 2007). However, relatively little is known about the mechanisms by which animals that are not in a direct danger share emotions.We have recently designed an experimental rat model of between-subject transfer of emotional information (Knapska et al. 2006). In this model, rats are housed in pairs and one member of the pair (the “demonstrator”) is removed and subjected to fear conditioning. After the fear-conditioning episode, the conditioned animal is allowed to interact with its naïve cage mate (the “observer”). We showed that the demonstrator''s fear is socially transferred to the observer, resulting in both rapid increase in exploratory behavior of the observer and a pattern of c-Fos activation in the observer''s amygdala that parallels that of the shocked demonstrators.These results suggest that the social interaction between the demonstrator and observer results in a transfer of information that promotes aversively motivated learning in the observer. However, the nature of the social interaction and how it comes to influence aversively motivated behavior is not known. Therefore, the present study aimed to characterize the behavior of both the demonstrators and observers during their social interaction and further characterize the nature of the influence of socially transmitted fear on aversively motivated learning and memory. We hypothesized that the social interaction between observers and demonstrators would result in a social transfer of fear that would promote learning and memory of both active defensive responses (avoidance) as well as defensive immobility (freezing). To test this hypothesis, we carried out five experiments that examined the nature of the social interaction between shocked demonstrators and observers (Experiment 1), the acquisition and retention of active avoidance (Experiment 2), and conditioned freezing (Experiment 3). Because it is not clear if social transfer effects can be observed among unfamiliar animals and to control for social buffering, we also compared the social transfer of fear in familiar and unfamiliar rats (Experiment 4). To control for the possible influence of different pain sensitivity thresholds in the observers paired with shocked demonstrators, we carried out pain tests (Experiment 5).  相似文献

Despite there has been a growing interest in the study of gratitude, few studies have investigated which factors support and promote it; notably, no study has yet addressed ways in which parents could promote gratitude in their children. The present study aims to investigate the relation between parental emotional support and self-esteem through the mediation of gratitude. The analyses have been conducted considering both the maternal and the paternal roles. To that end, an explorative model has been proposed of these relations. A self-report questionnaire was administered to 279 15–19 year-old adolescents (M?=?16.83, SD?=?.85) living in Northern Italy. Findings show that (a) the mother’s emotional support, but not the father’s, sustains gratitude, and (b) gratitude completely mediates the relation between maternal emotional support and self-esteem. Limitations and research implications are discussed.  相似文献

This paper argues the relevance of analysing the origins of contextual effects to explain subjective well-being (SWB). Using the 2012 European Social Survey, the study applies social capital indicators to distinguish between-context and between-individual heterogeneity in three multilevel models of happiness and life satisfaction. Five indicators of social capital at individual and regional level are used to measure the trust, networks and norms dimensions of social capital. Random intercept and random slope hierarchical models are used to control for unexplained regional variability. The possibility of aggregated subjective perceptions conditioning, or interacting with, the effects of individual perceptions is also examined. The results show that the regional means of the social capital indicators are useful in explaining not only average levels of SWB (between-context heterogeneity) but also differences in the importance individuals attribute to their social capital (between-individual heterogeneity). The paper also proposes a research agenda to expand the frontier on contextual effects in the new science of well-being.  相似文献

Conspiracy theories offer simple answers to complex problems by providing explanations for uncertain situations. Thus, they should be attractive to individuals who are intolerant of uncertainty and seek cognitive closure. We hypothesized that need for cognitive closure (NFCC) should foster conspiracy beliefs about events that lack clear official explanations, especially when conspiracy theories are temporarily salient. In Experiment 1, NFCC positively predicted the endorsement of a conspiracy theory behind the refugee crisis, especially when conspiratorial explanations were made salient. Experiment 2 showed that when conspiratorial explanations were made salient, NFCC positively predicted beliefs in conspiracies behind a mysterious plane crash. However, the link between NFCC and beliefs in conspiratorial explanations was reversed in the case of a plane crash with an official, non‐conspiratorial, explanation for the accident. In conclusion, people high (vs. low) in NFCC seize on conspiratorial explanations for uncertain events when such explanations are situationally accessible.  相似文献

Ethnicity is an important factor in premarital sexual debut as norms regarding appropriate sexual conduct outside of marriage vary considerably across cultures. Emerging adults of South Asian descent living in Western societies are an important demographic group, yet little is known about the factors that contribute to variations in their premarital sexual debut. The goal of this study was to investigate the contributions of parental sexual socialization and attitudes toward premarital sexual behaviors to premarital sexual debut in emerging adults of South Asian descent. University students of South Asian descent (N = 87) aged 18–24 completed a questionnaire containing measures of parental attitudes toward premarital sexual behaviors, their own attitudes toward premarital sexual behaviors, and experience with oral sex and intercourse. Mediation analyses showed that perceptions of mothers’ as more permissive toward premarital sexual behaviors was associated with respondents reporting more permissive attitudes toward premarital sexual behaviors, which in turn was associated with a greater likelihood of having engaged in oral sex and intercourse. No significant effect was found for fathers. These findings suggest that parental sexual socialization may influence emerging adults of South Asian descent’s decision to engage in premarital sexual behaviors through the process of sexual attitudes formation.  相似文献

Three studies examined the association between narcissistic identification with one’s advantaged in-group and engagement in solidarity-based collective action. Drawing on theory and past research, a negative effect of collective narcissism on solidarity-based collective action was expected. A two-wave longitudinal study (N = 162) found that Polish participants’ narcissistic, but not secure, national identification decreased their willingness to engage in collective action in solidarity with refugees over time. A field study (N = 258) performed during a mass protest against a proposed abortion ban showed that men’s gender-based collective narcissism was a negative predictor of solidarity-based engagement (operationalized as protest behavior and collective action intentions) and this effect was mediated by lowered empathy for women. Finally, a web-based survey (N = 1,992) revealed that heterosexual/cisgender individuals’ collective narcissism was negatively associated with collective action intentions in support of LGBT rights and that this effect was sequentially mediated by increased intergroup anxiety and decreased empathy for LGBT people. Theoretical implications of the present findings, research limitations, and future directions are discussed.  相似文献
