In order to develop normative data of a battery of neuropsychological tests in the mainland Chinese population, we examined the performance of 15 neuropsychological tests in 465 healthy subjects (231 males and 234 females) in a population‐based cohort study. The years of education were ranged between 1 and 23 years, and ages were ranged between 16 and 75 years old. The 15 neuropsychological tests cover five domains of neurocognitive functions including attention and speed of information processing, memory and learning, verbal function, visual constructive abilities, and executive function. We also assessed the effects of gender, age, educational attainment on the performance of these neuropsychological tests. The results showed that, as expected, educational attainment and age are the two main factors affecting performance in these tests. Educational attainment has the strongest predictive effect on all tests, while the majority of tests selected in this study are also affected by age at examination to varying degrees. The presented normative data will be useful for future studies in related clinical research, and be of value in transcultural neuropsychological studies.  相似文献

This research examined how Chinese children make moral judgments about lie telling and truth telling when facing a “white lie” or “politeness” dilemma in which telling a blunt truth is likely to hurt the feelings of another. We examined the possibility that the judgments of participants (7-11 years of age, N = 240) would differ as a function of the social context in which communication takes place. The expected social consequences were manipulated systematically in two studies. In Study 1, participants rated truth telling more negatively and rated lie telling more positively in a public situation where telling a blunt truth is especially likely to have negative social consequences. In Study 2, participants rated truth telling more positively and rated lie telling more negatively in a situation where accurate information is likely to be helpful for the recipient to achieve future success. Both studies showed that with increased age, children’s evaluations became significantly influenced by the social context, with the strongest effects being seen among the 11-year-olds. These results suggest that Chinese children learn to take anticipated social consequences into account when making moral judgments about the appropriateness of telling a blunt truth versus lying to protect the feelings of another.  相似文献

Research in the fields of complex problem solving (CPS) and dynamic decision making using microworlds has been mainly conducted in Western industrialized countries. This study analyzes the CPS process by investigating thinking-aloud protocols in five countries. Participants were 511 students from Brazil, Germany, India, the Philippines, and the United States who worked on two microworlds. On the basis of cultural-psychological theories, specific cross-national differences in CPS strategies were hypothesized. Following theories of situatedness of cognition, hypotheses about the specific frequency of problem-solving strategies in the two microworlds were developed. Results of the verbal protocols showed (a) modification of the theoretical CPS model, (b) task dependence of CPS strategies, and (c) cross-national differences in CPS strategies. Participants' CPS processes were particularly influenced by country-specific problem-solving strategies.  相似文献

Adding certain cardinality quantifiers into first-order language will give substantially more expressive languages. Thus, many mathematical concepts beyond first-order logic can be handled. Since basic modal logic can be seen as the bisimular invariant fragment of first-order logic on the level of models, it has no ability to handle modally these mathematical concepts beyond first-order logic. By adding modalities regarding the cardinalities of successor states, we can, in principle, investigate modal logics of all cardinalities. Thus ways of exploring model-theoretic logics can be transferred to modal logics.  相似文献

Smoking cues that increase craving are subjectively described by smokers as pleasant rather than unpleasant. However, it remains controversial whether the motivational nature of these smoking cues is consistent with an appetitive or aversion-relief model of tobacco craving. In the two studies presented here, the Bioinformational model of emotion proposed by Lang was used to address this issue. In study I, 40 smokers (10 males) assessed a set of tobacco-related pictures and a subset of standard pleasant, neutral, and unpleasant pictures in order to examine how craving relates to the three general dimensions of emotion: valence, arousal, and dominance. Results showed that the tobacco-related images were all assessed as appetitive, and craving was correlated positively with valence (r = .863, p < .0001) and arousal (r = .923, p < .0001) and negatively with dominance (r = −.504, p < .002). In study II, 24 female abstinent smokers were examined using Lang’s startle modulation paradigm in order to assess whether tobacco-related pictures, compared to standard pleasant and unpleasant ones, inhibited the startle response, consistent with an appetitive model of tobacco craving. Contrary to expectations, the startle response during visualization of tobacco-related pictures was more similar in magnitude to the response to unpleasant than to pleasant images, a finding inconsistent with an appetitive model of tobacco craving.  相似文献

Resumen

En esta investigación se evaluó el papel que juegan las diferencias individuales en una situación de tolerancia a la estimulación aversiva. Ochenta sujetos divididos en alto-autocontroladores y bajo-autocontroladores, según la puntuación obtenida en la Escala de Autocontrol de Rosenbaum, fueron sometidos a una prueba de presión por frío. Los objetivos fundamentales del estudio fueron: (1) comprobar si sujetos altos y bajos en autocontrol presentan diferencias al enfrentarse al cold-pressor en tolerancia y malestar percibido; (2) comprobar el tipo de estrategias que utilizan los sujetos altos y bajos para enfrentarse a la estimulación aversiva, y su eficacia; (3) comprobar si la utilización de una estrategia distractiva-agradable o de una estrategia que resalta la propia competencia del sujeto frente a la situación aversiva afecta diferencialmente a los sujetos altos y bajos en autocontrol en las medidas de tolerancia del sujeto frente a la situación aversiva afecta diferencialmente a los sujetos altos y bajos en autocontrol en las medidas de tolerancia y malestar percibido. Los resultados de los análisis de covarianza realizados no mostraron diferencias significativas entre los sujetos altos y bajos en autocontrol en el tiempo de tolerancia al agua helada, ni en el malestar percibido durante la prueba, aunque en esta última variable se encontró una interacción significativa entre grupos experimentales y niveles de autocontrol. Se discuten estos resultados.  相似文献

Developmental studies have demonstrated that cognitive processes such as attention, suppression of interference and memory develop throughout childhood and adolescence. However, little is currently known about the development of top-down control mechanisms and their influence on cognitive performance. In the present study, we used functional magnetic resonance imaging to investigate modulation of activity in the ventral visual cortex in healthy 7–11-year-old children and young adults. The participants performed tasks that required attention to either face (Fs task) or scene (Sf task) images while trying to ignore distracting scene or face images, respectively. A face-selective area in the fusiform gyrus (fusiform face area, FFA) and an area responding preferentially to scene images in the parahippocampal gyrus (parahippocampal place area, PPA) were defined using functional localizers. Children responded slower and less accurately in the tasks than adults. In children, the right FFA was less selective to face images and regulation of activity between the Fs and Sf tasks was weaker compared to adults. In the PPA, selectivity to scenes and regulation of activity, there according to the task demands were comparable between children and adults. During the tasks, children activated prefrontal cortical areas including the middle (MFG) and superior (SFG) frontal gyrus more than adults. Functional connectivity between the right FFA and left MFG was stronger in adults than children in the Fs task. Children, on the other hand, had stronger functional connectivity than adults in the Sf task between the right FFA and right PPA and between right MFG and medial SFG. There were no group differences in the functional connectivity between the PPA and the prefrontal cortex (PFC). Together the results suggest that, in 7–11-year-old children, the FFA is still immature, whereas the selectivity to scenes and regulation of activity in the PPA is comparable to adults. The results also indicated functional immaturity of the PFC in children compared to adults and weaker connectivity between the PFC and the rFFA, explaining the weaker regulation of activity in the rFFA between the Fs and Sf tasks.  相似文献

This research note investigates the association between mobile payment adoption and happiness. We employ the conditional mixed process model to address the selection bias and estimate the open-access 2017 Chinese General Social Survey data. Our findings reveal that mobile payment adoption significantly improves rural residents’ happiness but does not significantly influence urban residents’ happiness. Exploring gendered differences finds that regardless of urban or rural residence, females are happier than males when adopting mobile payment. Our findings suggest that promoting mobile payment adoption could bring favourable well-being returns.
