The present study investigated the psychological health effects and motivational origins of digital stress based on a representative survey of 1,557 German Internet users between 14 and 85 years of age. Communication load resulting from private e-mails and social media messages as well as Internet multitasking were positively related to perceived stress and had significant indirect effects on burnout, depression, and anxiety. Perceived social pressure and the fear of missing out on information and social interaction were key drivers of communication load and Internet multitasking. Age significantly moderated the health effects of digital stress as well as the motivational drivers of communication load and Internet multitasking. The results, thus, underline the need to address digital stress from a life span perspective.  相似文献

The recollective qualities of autobiographical memory are thought to develop over the course of the first two decades of life. We used a 9-year follow-up test of recall of a devastating tornado and of non-tornado-related events from before and after the storm, to compare the recollective qualities of adolescents’ (n?=?20, ages 11 years, 11 months to 20 years, 8 months) and adults’ (n?=?14) autobiographical memories. At the time of the tornado, half of the adolescents had been younger than age 6. Nine years after the event, all participants provided evidence that they recall the event of the tornado. Adults also had high levels of recall of the non-tornado-related events. Adolescents recalled proportionally fewer non-tornado-related events; adolescents younger than 6 at the time of the events recalled the fewest non-tornado-related events. Relative to adolescents, adults produced longer narratives. With narrative length controlled, there were few differences in the recollective qualities of adolescents’ and adults’ narrative reports, especially in the case of the tornado; the recollective qualities were stronger among adolescents older at the time of the events. Overall, participants in both age groups provided evidence of the qualities of recollection that are characteristic of autobiographical memory.  相似文献

A typology of churched and unchurched religions is developed and then used to analyse the status of unchurched spirituality in the United States, Sweden, and Japan. In the United States, churched religions remain strong, while most of those who say they have no religious preference are quite religious, merely unchurched. In Sweden, the lack of participation in the state church seems to be more than offset by a rapid rise in unchurched religion, especially among the young. Japan's celebrated lack of religion is found to be merely a lack of churched religions, as the Japanese are devoted followers of unchurched faiths. In conclusion, the relative lack of authority of unchurched religions is examined.  相似文献

Our goals in this article were to use item response theory (IRT) to assess the relation of depressive symptoms to the underlying dimension of depression and to demonstrate how IRT-based measurement strategies can yield more reliable data about depression severity than conventional symptom counts. Participants were 3,403 children and adolescents from 12 contributing clinical and nonclinical samples; all participants had received the Kiddie Schedule of Affective Disorders and Schizophrenia for School-Aged Children. Results revealed that some symptoms reflected higher levels of depression and were more discriminating than others. Furthermore, use of IRT-based information about symptom severity and discriminability in the measurement of depression severity was shown to reduce measurement error and increase measurement fidelity.  相似文献

The goal of the present study was to elucidate the role of the human striatum in learning via reward and punishment during an associative learning task. Previous studies have identified the striatum as a critical component in the neural circuitry of reward-related learning. It remains unclear, however, under what task conditions, and to what extent, the striatum is modulated by punishment during an instrumental learning task. Using high-resolution functional magnetic resonance imaging (fMRI) during a reward- and punishment-based probabilistic associative learning task, we observed activity in the ventral putamen for stimuli learned via reward regardless of whether participants were correct or incorrect (i.e., outcome). In contrast, activity in the dorsal caudate was modulated by trials that received feedback--either correct reward or incorrect punishment trials. We also identified an anterior/posterior dissociation reflecting reward and punishment prediction error estimates. Additionally, differences in patterns of activity that correlated with the amount of training were identified along the anterior/posterior axis of the striatum. We suggest that unique subregions of the striatum--separated along both a dorsal/ventral and anterior/posterior axis--differentially participate in the learning of associations through reward and punishment.  相似文献

In order to examine the role of left perisylvian cortex in spelling, 13 individuals with lesions in this area were administered a comprehensive spelling battery. Their spelling of regular words, irregular words, and nonwords was compared with that of individuals with extrasylvian damage involving left inferior temporo-occipital cortex and normal controls. Perisylvian patients demonstrated a lexicality effect, with nonwords spelled worse than real words. This pattern contrasts with the deficit in irregular word spelling, or regularity effect, observed in extrasylvian patients. These findings confirm that damage to left perisylvian cortex results in impaired phonological processing required for sublexical spelling. Further, degraded phonological input to orthographic selection typically results in additional deficits in real word spelling.  相似文献

The functionalist "law" that religion sustains the moral order must be amended. As is demonstrated in this study, religion has this effect only as it is based on belief in powerful, active, conscious, morally-concerned gods. Contrary to Durkheim's claims, participation in religious rituals per se has little independent impact on morality and none when done on behalf of gods conceived as unconscious essences, or as conscious gods of small scope and lacking moral concerns. Thus, the link between gods and morality is limited mainly to societies having more complex cultures, but even in some highly developed societies a religious basis for morality is missing. Quantitative results are based on 427 societies included in the Atlas of World Cultures, and on surveys of the United States and 33 other nations.  相似文献

When Ms. was first introduced as an alternative to Miss or Mrs. it was perceived as a radical feminist innovation. Today, its use is unremarkable, even normative. This study examines two aspects of the meaning of Ms.: changes in its connotative meaning over time, and its current comparability to other titles. Female (n = 83) and male (n = 54) college students rated courtesy titles (Ms., Miss, Mrs., Mr.) on a set of bipolar adjective pairs composing a semantic differential scale in an exact replication of a 1978 study. Of the four titles, the largest change in meaning over time was for Ms., and the direction of the change was positive. These results document the social assimilation of a new gender-related concept.  相似文献
