We aimed to investigate whether exposure to the Chinese famine (1959–1961) in early life was associated with depression in adulthood. We included 17,505 participants from the China health and retirement longitudinal study (CHARLS). Participants were classified into indirect and direct exposure groups. And the directly exposure groups including prenatal, childhood, adolescence/adult exposure groups. Depression was diagnosed by Center for Epidemiological Studies Depression Scale-10 (CES-D) score. Multivariate logistic regression model was used to calculate the odd ratios (ORs) and 95% confidence intervals (CIs) of depression. In women, prenatal, childhood, adolescence/adult exposure groups had higher depression risk than indirect exposure group (OR = 1.46, 1.40, and 1.67, respectively). However, there was no significant association between famine exposure and depression among men. Exposure to famine during prenatal (OR: 1.48; 95% CI: 1.07–2.06), childhood (OR: 1.47; 95% CI: 1.13–1.91), and adolescence/adult (OR: 1.63; 95% CI: 1.24–2.15) period were associated with depression among subjects living in rural, but not those living in urban. Exposure to the Chinese famine in early life had sex and area-specific associations with depression. 相似文献

This paper reports mainland Chinese students’ self-appraisals about their psychological dispositions whilst at school. Increasing interest has turned to factors such as resilience, wellbeing, flourishing, happiness and satisfaction, which in turn are predicted to be associated with factors such as emotional stability, achieving personal goals, social fulfilment and quality of life. Such psychological dispositions are developed in conjunction with the influences of social systems such as schools. Although a number of researchers have collaborated with schools to investigate students’ dispositions in English speaking countries, similar research in mainland China is in its infancy. This is particularly the case for studies that seek students’ own perspectives. We administered a questionnaire about resilience, flourishing, wellbeing, self-concept, school satisfaction, mental health, and happiness at school to 2756 students in Years 5–9 in mainland China. As expected with a non-clinical population, most students reported positively across the various scales. However, dividing the sample into subgroups enabled the creation of stratified visual profiles that showed significant differences between students with different backgrounds, such as gender, age, and mental health. This study illustrates the importance of subgroup analyses to identify potential areas of concern for different types of students, which in turn may inform differentiated school-based intervention programs to support students to flourish. 相似文献

Fish typically prefer to live in big shoals due to the associated ecological benefits. Shoaling is a behavior that depends on the ability to quantitatively discriminate. The fundamental mechanism involved in quantity discrimination determines whether fish can discriminate a shoal using numerical discrete cues (e.g., number of shoal members), non-numerical continuous traits (e.g., total body surface area) or both; however, the mechanism is currently a controversial topic. In the present study, we used a spontaneous choice experiment to test whether guppy (Poecilia reticulata), zebrafish (Danio rerio), Chinese crucian carp (Carassius auratus) and qingbo (Spinibarbus sinensis) rely on continuous (i.e., body surface area) or discrete (i.e., number of shoal members) information for shoal selection by altering the body surface area (cumulative body surface area ratio of 3:2 or 1:1) between two stimulus shoals with a different number of members (2 individuals vs 3 individuals). All four fish species preferred to shoal with the stimulus shoal with the larger cumulative surface area even if the shoal had fewer members; however, fish showed no shoal preference when the cumulative surface body areas of both stimulus shoals were equal. Furthermore, qingbo did not numerically discriminate between a shoal with 1 individual and a shoal with 3 individuals when the cumulative surface areas of both stimulus shoals were equal; however, qingbo showed a preference for the shoal with the larger cumulative surface area when the two stimulus shoals each had 3 individuals. In conclusion, the present study demonstrated that all four fish species relied only on non-numerical continuous quantity information for shoal selection, at least under a difficult task (i.e., 2 vs 3). 相似文献

从概念结构和测量工具角度对相关文献进行系统梳理和剖析发现:既有研究主要集中于患方视角而相对忽视了医方信任测量;测量维度上存在各种不同指标,主要涉及医患双方在就医过程中的态度、能力和行为,以及二者对医患关系亲密程度感知的心理结构。总结不同视角的相关研究,本研究提出了医患信任关系的总体概念框架和医患信任测量的整合模型,旨在构建医患信任测量的总体框架及测量指标,以期为后续研究和实践工作提供参考和指导。 相似文献

The visual system is remarkably efficient at extracting summary statistics from the environment. Yet at any given time, the environment consists of many groups of objects distributed over space. Thus, the challenge for the visual system is to summarize over multiple groups. The current study investigates the capacity and computational efficiency of ensemble perception, in the context of perceiving mean sizes of multiple spatially intermixed groups of circles. In a series of experiments, participants viewed an array of one to eight sets of circles. Each set contained four circles in the same colors, but with different sizes. Participants estimated the mean size of a probed set. The set that would be probed was either known before onset of the array (pre-cue condition) or afterwards (post-cue condition). By comparing estimation error in the pre-cue and post-cue conditions, we found that participants could reliably estimate mean sizes for approximately two sets (Experiment 1). Importantly, this capacity was robust against attention bias toward individual objects in the sets (Experiment 2). Varying the exposure time to stimulus arrays did not increase the capacity limit, suggesting that ensemble perception could be limited by an internal resource constraint, rather than the speed of information encoding (Experiment 3). Moreover, we found that the visual system could not encode and hold more individual items than ensemble representations (Experiment 4). Taken together, these results suggest that ensemble perception provides an efficient way of information processing but with constraints. 相似文献

情感韵律在真假句子加工上的差异:来自ERPs的证据 总被引:1,自引:0,他引:1
采用事件相关电位(ERP)技术探讨语义-情感韵律的神经生理机制。六种基本情绪类型的韵律分两种条件呈现给被试,即假句子的韵律预期偏差条件和真句子的语义-韵律预期偏差条件。研究结果表明两种预期偏差是纯粹的价独立,无论情感价正性还是负性都会得出相同的ERP效应;六种情感韵律都诱发了右单侧化的ERP正波效应,而语义-情感韵律都诱发了早期双侧化分布的ERP负波效应。本研究进一步证实了情感韵律和语义-情感韵律加工的时间进程的差异性;同时,无论是有语义的真句子和无语义的假句子,情感韵律都能够提高表达的目的意图。 相似文献

The decision strategy adopted by an observer in a psychophysical procedure may be established by comparing estimates of sensitivity obtained by using detection-theoretic models based on each of the available decision strategies. Estimates of sensitivity obtained from 10 observers on auditory-level discrimination tasks using the yes/no, two-alternative forced choice (2AFC), and 2AFC with reminder (2AFCR; sometimes called duo-trio) procedures were compared in order to determine the decision strategy used by the judges in the 2AFCR procedure. 2AFCR permits at least three decision strategies: differencing, likelihood ratio, and comparison of distances. The latter strategy has frequently been assumed in the analysis of duo-trio data in the sensory evaluation literature. The present study demonstrates that the comparison-of-distances strategy was not used by 9 of the 10 observers in this auditory experiment. The nature of the instructions given to the observers had no measurable impact on the decision strategy that they adopted. 相似文献

This article reports a meta-analysis of energy expenditure (EE) of playing active video games (AVGs). In particular, heart rate (HR), oxygen consumption (VO2), and EE were assessed and three moderators for the effects of AVGs--types of AVG, player age, and player weight status--were analyzed. The results show that playing AVGs significantly increased HR, VO2, and EE from resting. The effect sizes of playing AVGs on HR, VO2, and EE were similar to traditional physical activities. AVG type and player age were significant moderators for the effects of AVGs. The finding suggests that AVGs are effective technologies that may facilitate light- to moderate-intensity physical activity promotion. 相似文献
