A model of sustained volunteerism in young people is proposed. The longitudinal study addresses the questions “Why do young people decide to continue to volunteer over an extended period of time?” There were 158 volunteers (82 female and 76 male). The volunteers completed measures of motivation to volunteer, integration, and satisfaction with the organization, merged effects due to voluntary service, social support, identity, and intention to volunteer on a first (Time 1) and a second research wave (Time 2). Results show that both dispositional and organizational variables are important in determining long-term volunteerism in young people and confirmed that role identity is the best predictor of intention to volunteer. 相似文献

The authors describe an interruption in communication in the analyses of two patients, which gradually brings the analytic process to a halt/standstill. They propose several hypotheses for understanding this situation. One explanation is mutual identification of primitive superegos in the analytic couple which generates a moralizing effect thereby hindering investigation and discovery. They emphasize the importance of countertransference involvement which partly provokes this particular type of impasse. They also suggest the idea of shared acting out, with complementary participations of analyst and patient. In this way the analytic couple supports a 'bastion' which protects against the risk of breaking the omnipotence of patient and analyst or contributes to this omnipotence. Their shared unconscious phantasy feeds collusion linked to unconscious persecutory guilt. The authors also describe movements to break free from this impasse. The enclave created by the analytic couple is detected and subsequently worked through by way of the patient's contribution of dream material and the analyst's work with her countertransference. 相似文献

Abstract— Although another person's experience of recollection cannot be observed directly, we have found that the underlying operations can be monitored using noninvasive electrophysiological techniques. Results from two experiments showed that brain potentials elicited 500 to 900 ms after the onset of visually presented words vary systematically in amplitude with manipulations that influence the extent to which subjects engage in recollective processing. These brain potentials can thus be construed as correlates of the subjective experience of recollection 相似文献

In tonal languages, as Mandarin Chinese and Thai, word meaning is partially determined by lexical tones. Previous studies suggest that lexical tones are processed by native listeners as linguistic information and not as pure tonal information. This study aims at verifying if, in nontonal languages speakers, the discrimination of lexical Mandarin tones varies in function of the melodic ability. Forty-six students with no previous experience of Mandarin or any other tonal language were presented with two short lists of spoken monosyllabic Mandarin words and invited to perform a same–different task trying to identify whether the variation were phonological or tonal. Main results show that subjects perform significantly better in identifying phonological variations rather than tonal ones and interestingly, the group with a high melodic ability (assessed by Wing subtest 3) shows a better performance exclusively in detecting tonal variations. 相似文献

Age-related changes in sensory, lexical, and sentence processing were examined and compared using event-related potentials (ERPs) recorded as young and elderly participants listened to natural speech for comprehension. Lexically associated and unassociated word pairs were embedded in meaningful or syntactically legal but meaningless sentences. Early, general sensory, and attention-related responses (N1, P2) were delayed by about 25 ms for older participants, but later components indexing semantic processing (N400) were not delayed. There were no differences in the size, timing, or distribution of lexical associative effects for the two groups. In contrast, message-level context effects were delayed by more than 200 ms in the elderly group. The results support models that posit age-related changes primarily in higher order language processes. 相似文献

In this contribution I intend to reconstruct and evaluate one of Galileo's famous arguments given in the Discorsi against a well‐entrenched thesis of Aristotelian physics. It will be shown that Galileo's reduction‐to‐the‐absurd type of counterargument is, although seemingly cogent, after all fallacious. I ascribe Galileo's committing of this fallacy to his looking at the Aristotelian physics through the (Kuhnian type) paradigmatic “spectacles” of his own new physics. 相似文献

Chronic consumption of ethanol during pregnancy and lactation may lead to abnormalities in the fetus or infant. A group of female Wistar rats was submitted to ethanol treatment over a period of a month. A pair-fed control group received sucrose solution isocaloric to ethanol and the control group received water “ad libitum.” Afterward, the females were mated with males over a period of 20 days. At birth, each litter was maximized to eight pups and the remaining ones were decapitated to remove the fetal blood and brains. No significant difference was observed in fetal body and brain weight at birth. During lactation the ethanol and pair-fed groups gained less weight than the control group. After weaning, their weight became similar. Fetal blood glucose levels were decreased in the ethanol-treated group. One hundred percent of the pair-fed and control females delivered live fetuses at term and all survived; only 40% of the females in the ethanol group delivered, and one pup did not survive. Chronic ethanol treatment pointed to a possible reduction in the fertility. It seems likely that the change in body weight of ethanol-fed dams was caused by undernutrition. 相似文献

Resilience refers to the process by which individuals use the ability to cope with challenges to successfully adapt to adverse situations, inclining towards the future and hope. The main aim of this study was to analyze the relation between resilience, personality traits, and hopelessness. Furthermore, we conducted comparisons between two age groups: young and older adults. The sample comprised 439 Spanish participants (66.7% women; M = 43.73, SD = 26.41; age range = 18–98 years). The Connor–Davidson Resilience Scale, NEO-Five Factor Inventory, and Beck Hopelessness Scale were used to measure the main study variables. The results revealed a negative relation between resilience and neuroticism, and a positive association with the other personality traits. Additionally, levels of resilience were found to be negatively related to hopelessness. The group of older adults showed significantly lower resilience levels than the young adults, although age was not a significant predictor of resilience. Neuroticism, extraversion, openness, and hopelessness were the only predictors of resilience for the current study. This work contributes to the study of resilience and related factors, by attempting to understand the role of resilience and resistance to risk and how individuals tackle challenges over time, with important implications for mental health. 相似文献
