Aerial respiratory behavior in the pond snail Lymnaea was operantly conditioned so that snails learned not to perform aerial respiration in a hypoxic environment. Snails were trained in either the standard context (no food odorant) or a carrot (food-odorant) context. An operant training procedure of two 45-min training sessions with a 1-h interval between the sessions followed by a third 45-min training session 18 h later was sufficient to produce associative learning and long-term memory (LTM) that persisted for at least 5 days. If, however, following the third operant training session snails received three 45-min extinction training sessions, with each extinction session separated by at least a 1-h interval, LTM was not observed when tested the following day. That is, the memory was extinguished. Extinction, however, did not occur if the context of the extinction training was different from the context of the associative training. That is, in the snails trained in the standard context, extinction did not occur if the extinction training sessions were performed in the food-odorant context and vice versa. 相似文献

Does COVID-19 affect people of all classes equally? In the current research, we focus on the social issue of risk inequality during the early stages of the COVID-19 pandemic. Using a nationwide survey conducted in China (N = 1,137), we predicted and found that compared to higher-class individuals, lower-class participants reported a stronger decline in self-rated health as well as economic well-being due to the COVID-19 outbreak. At the same time, we examined participants' beliefs regarding the distribution of risks. The results demonstrated that although lower-class individuals were facing higher risks, they expressed lesser belief in such a risk inequality than their higher-class counterparts. This tendency was partly mediated by their stronger endorsement of system-justifying beliefs. The findings provide novel evidence of the misperception of risk inequality among the disadvantaged in the context of COVID-19. Implications for science and policy are discussed. 相似文献

Based on the theory of appraisal, we predicted that positive and negative events happening to the same people or things in a specific chronological order (i.e., a negative event following a positive event) would induce different mixed feelings than the same events happening to different people or things. Pairs of emotional pictures with different captions were used to create two event groups. In the “tragic event” group, the positive and negative events happened to the same person or things, and in the “tragicomic event” group, the positive and negative events happened to different people or things. We designed two experiments to explore and compare the generation of mixed feelings in those two groups. In Experiment 1, the negative event was shown first, and in Experiment 2, the negative event was shown second (although the chronological order of the depicted events was the same). The participants were 381 undergraduates: 195 in Experiment 1 and 186 in Experiment 2. In both experiments, we found that tragic events introduced less intense mixed feelings than did tragicomic events due to fewer pleasurable feelings induced by the tragic events. There was no significant difference in the report of negative emotions between the groups. Appraisal theory and negative bias effects may explain these results. 相似文献

从网络同一性实验与自我同一性间关系的分歧出发,提出相应的理论模型,考察网络社交倾向的调节作用及强迫性网络使用的中介作用。本研究采用网络同一性实验量表、自我同一性实验问卷以及强迫性网络使用量表对275名大学生进行了测量,结果表明:(1)网络社交倾向对网络同一性实验与自我同一性的关系具有调节作用。对于线下社交倾向的大学生,网络同一性实验对自我同一性有消极预测作用;但对于线上社交倾向的大学生,中等程度的网络同一性实验会积极预测自我同一性的发展;(2)强迫性网络使用在网络同一性实验与自我同一性的关系中起完全中介作用。总之,网络同一性实验整体上不利于大学生自我同一性的发展,但若把握好"度"也可以发挥其积极作用。 相似文献

To clarify the influence of disciplinary culture on the materialism–subjective well-being (SWB) relationship, as well as the relationship between changes in materialism and changes in SWB, the current longitudinal study tracked the levels of materialism and SWB among first-year undergraduates for 12 months. A total of 218 participants from a congruent disciplinary culture (i.e., business school) and 210 participants from an incongruent disciplinary culture (i.e., engineering school) provided ratings on the Material Values Scale, the Satisfaction with Life Scale, and the Positive and Negative Affect Schedule in three waves. The following results were obtained: (1) the interaction effect of disciplinary culture and time was significant. In Wave 3, the level of materialism in business school was significantly higher than that in engineering school, but this difference was not found in Waves 1 and 2; (2) the negative relationship between materialism and SWB remained stable over time and was not moderated by disciplinary culture. Moreover, disciplinary culture did not moderate the relationship between changes in materialism and changes in SWB. The above findings indicate that disciplinary culture influences the development of materialism but not the materialism–SWB relationship in the long term. 相似文献

The present research investigates the applicability of prominent Western volunteering frameworks in Hong Kong. Two cross‐sectional surveys involving a total of 268 respondents were conducted. In Study 1, we tested a model of volunteering among 149 Hong Kong Chinese adult individuals (Mage = 34.8 years; 51.7% female) that examines antecedents and outcomes of voluntary engagement. Results show that prosocial motivation relates to volunteering, and that volunteering in turn predicts life satisfaction. Unexpectedly, and unlike studies in Western settings, other‐oriented empathy was not related to volunteering. Study 2 tests the propositions of the Volunteer Process Model (VPM) among 119 Hong Kong Chinese volunteers (Mage = 36.9 years; 58.0% female). Findings largely support the VPM: our results indicate that the link between motives, voluntary service length and frequency is mediated by satisfaction with volunteering. Moreover, findings suggest that a fit between motives and experience seems relevant for increasing volunteers' satisfaction with their service. Results of both studies suggest that Western volunteering models can be applied to volunteering in East Asian cultures when culture‐specific adaptations are considered. 相似文献

Self-supporting personality (SSP) is an indigenous Chinese personality concept. It is assumed to be a protective personality factor with regard to depression. In the present study, self-supporting personality traits are assumed to be similar to Big Five personality traits or facets of the Five Factor Model to a considerable degree, but also to contain some tendencies or dispositions which are related to depression in ways that go beyond either the Big Five factors or their sub-factors. The relation of self-supporting personality, Big Five personality, and depression was examined in a sample of 439 Chinese undergraduate students using the Self-Supporting Personality Scale for Adolescent Students (SSPS-AS), the Mandarin Chinese version of Revised NEO Personality Inventory (NEO-PI-R), and the Chinese Version of Self-Rating Depression Scale (SDS). Results from the correlation analysis revealed that most SSP traits were significantly correlated with the Big Five personality dimensions and sub-dimensions, but the correlation between personal flexibility and either the Big Five dimensions or their sub-dimensions were modest at best. Results from the hierarchical linear regression analyses showed that interpersonal responsibility, interpersonal openness, and personal independence negatively predicted depression, even after controlling for demographic variables and the Big Five personality, however, the explained variance decreased sharply. These results support the hypothesis that despite some overlap with the Big Five personality, self-supporting personality is related to depression in additional ways that the Big Five personality dimensions or their sub-dimensions are not. 相似文献

Several psychophysical studies of visual short-term memory (VSTM) have shown high-fidelity storage capacity for many properties of visual stimuli. On judgments of the spatial frequency of gratings, for example, discrimination performance does not decrease significantly, even for memory intervals of up to 30 s. For other properties, such as stimulus orientation and contrast, however, such “perfect storage” behavior is not found, although the reasons for this difference remain unresolved. Here, we report two experiments in which we investigated the nature of the representation of stimulus contrast in VSTM using spatially complex, two-dimensional random-noise stimuli. We addressed whether information about contrast per se is retained during the memory interval by using a test stimulus with the same spatial structure but either the same or the opposite local contrast polarity, with respect to the comparison (i.e., remembered) stimulus. We found that discrimination thresholds got steadily worse with increasing duration of the memory interval. Furthermore, performance was better when the test and comparison stimuli had the same local contrast polarity than when they were contrast-reversed. Finally, when a noise mask was introduced during the memory interval, its disruptive effect was maximal when the spatial configuration of its constituent elements was uncorrelated with those of the comparison and test stimuli. These results suggest that VSTM for contrast is closely tied to the spatial configuration of stimuli and is not transformed into a more abstract representation. 相似文献
