The relationship between preschoolers' understanding of considerate socially-mindful actions and theory of mind
Xin Zhao, Dandan Li et al.ARTICLEActa Psychologica Sinica2022
摘要: 本文探究了4~6岁儿童社会善念理解的发展及其与心理理论的关系。研究测量了100名4~6岁儿童的社会善念理解、心理理论、亲社会性和执行功能。结果发现, 随着年龄增长, 儿童愈加在社会评价和朋友偏好上倾向于社会善念人物, 并且此社会善念理解能力与心理理论的发展呈显著正相关, 且此相关在控制了年龄、执行功能及亲社会性后依然稳定存在, 但社会善念理解与亲社会性并不相关。此结果表明, 心理理论可能对社会善念理解的发展有重要作用
Distinct roles of perceived teacher and peer relationships in adolescent students’ academic motivation and outcomes
Open AccessDiyue Liu, Yi Jiang et al.ARTICLEJournal of Pacific Rim Psychology2022
In the learning environment, both teachers and peers are influential social agents. In the present study, we differentiated between positive and negative aspects of teacher and peer relationships and examined how they predict adolescent students’ academic interest and self-concept, which in turn lead to different levels of academic achievement and subjective well-being at school. Additionally, we explored whether father absence moderated these pr…

Direct versus indirect climate controls on Holocene diatom assemblages in a sub-tropical deep, alpine lake (Lugu Hu, Yunnan, SW China)
Open AccessQian Wang, Xiangdong Yang et al.ARTICLEQuaternary Research2016
The reconstruction of Holocene environmental changes in lakes on the plateau region of southwest China provides an understanding of how these ecosystems may respond to climate change. Fossil diatom assemblages were investigated from an 11,000-year lake sediment core from a deep, alpine lake (Lugu Hu) in southwest China, an area strongly influenced by the southwest (or the Indian) summer monsoon. Changes in diatom assemblage composition, notably t…
Climate and tectonic effects on Holocene development of an alpine lake (Muge Co, SE margin of Tibet)
Open AccessZhujun Hu, N John Anderson et al.ARTICLEThe Holocene2015References: 10
South-west China is an important area for determining variability of the SW Asian Monsoon; it is, however, also tectonically very active. Palaeolimnological studies in this region generally focus on climate as a direct driver of ecological change, rarely considering the effects of tectonic activity and catchment ontogeny. We present diatom and organic matter data from a Holocene sediment record from Muge Co, an alpine lake located on an active fa…
Diatom response to Asian monsoon variability during the Late Glacial to Holocene in a small treeline lake, SW China
Open AccessXu Chen, Chen Xu et al.ARTICLEThe Holocene2014Cited by: 4References: 7
Analyses of diatoms, grain size, magnetic susceptibility, total organic carbon, and total nitrogen were applied to a 9.26 m long sediment core, spanning the last 12.2 kyr, from a small treeline lake (Tiancai Lake, ~3898 m a.s.l.) in southwest China. Diatom assemblages are dominated by Cyclotella distinguenda, Aulacoseira species, and small fragilarioid taxa, all of which are sensitive to changes in water pH and light conditions that are probably …

Modeling Language Components in Mathematical Items Using Multiple Random Effects IRT Models
Xiangdong Yang, Xiang-Dong YANG et al.ARTICLEActa Psychologica Sinica2012
摘要: 数学应用题中的语言成分可能对被试问题解决过程产生复杂影响。通常, 这种影响对所有被试并非完全一致, 而是具体数学题目特征与特定被试的认知特性之间交互作用的结果。本研究采用多元随机效应项目反应理论模型的建模方法, 分析了数学应用题中语言成分对问题解决过程的影响。该方法的优势在于它不仅分析了语言成分对数学问题解决过程的平均效应, 同时给出了相应的随机效应, 揭示了相应成分对不同个体问题解决过程的具体影响程度。结果表明, 较难的项目倾向于单词更多, 命题密度更高, 要求对图/表信息进行编码和转译, 或者根据问题表述生成数学公式。项目命题密度影响效应存在着显著的个别差异。项目命题密度对能力较低的被试的影响高于对能力较高的被试的影响
Vegetation history and dynamics in the middle reach of the Yangtze River during the last 1500 years revealed by sedimentary records from Taibai Lake, China
Open AccessXiayun Xiao, Xiangdong Yang et al.ARTICLEThe Holocene2012References: 13
Pollen and charcoal records of a 150 cm long lake sediment core from Taibai Lake in the middle reach of the Yangtze River reveal seven major changes in regional vegetation over the last 1500 years. During the period c. ad 480–710, evergreen broadleaved forest dominated by Castanopsis/Lithocarpus and evergreen oaks occurred in the Taibai Lake catchment. From c. ad 710 to 1050, the vegetation shifted to a mixed conifer and broadleaved forest, with …
The Impact on Ability Estimates of Predicted Parameters from Cognitively Designed Items in a Computerized Adaptive Testing Environment
Xiangdong Yang, Xiang-Dong YANGARTICLEActa Psychologica Sinica2010
摘要: 自动化项目生成(Automatic Item Generation)中的项目参数是基于认知项目设计的刺激特征集预测的, 在不确定性来源上较之用经验数据标定的参数更为复杂。文章通过实证研究分析了在计算机适应性测验条件下基于认知设计系统法生成的抽象推理测验(ART)项目预测参数对能力参数估计的精确性。研究表明, 项目预测参数比相应标定参数分布更为趋中。这种回归效应既影响到能力参数估计误差大小, 也导致适应性测验过程中项目选择的差异。在控制了项目选择差异之后, 能力参数估计误差较之基于项目标定参数的能力估计误差大, 但差别并不明显。两者相应的能力估计值相关很高, 对应能力值之间的差异很小, 且几乎贯彻整个能力分布区间
Methods of Identifying Individual Guessers From Item Response Data
Open AccessXiangdong Yang, Xiangdong Yang Xiangdong YangARTICLEEducational and Psychological…2007
This article investigates several methods of identifying individual guessers from their response data. Both the posterior probability method and the likelihood ratio method are based on the two-state mixture modeling approach to response times. The accuracy method is based on response accuracy data. Results from the simulation study showed that under similar classification criterion, the likelihood ratio method had a higher rate of correctly iden…

Measuring Attentional Ability in Older Adults
Open AccessLesa Hoffman, Xiangdong Yang et al.ARTICLEEducational and Psychological…2006
Although deficits in visual attention are often postulated as an important component of many declines in cognitive processing and functional outcomes in older adults, surprisingly little emphasis has been placed on evaluating psychometric instruments with which individual differences in visual attention ability can be assessed. This article reports the development and beginning psychometric evaluation of DriverScan, a change detection measure of …
Effects of Estimation Bias on Multiple-Category Classification With an IRT-Based Adaptive Classification Procedure
Open AccessXiangdong Yang, John C Poggio et al.ARTICLEEducational and Psychological…2006
The effects of five ability estimators, that is, maximum likelihood estimator, weighted likelihood estimator, maximum a posteriori, expected a posteriori, and Owen's sequential estimator, on the performances of the item response theory–based adaptive classification procedure on multiple categories were studied via simulations. The following results were found. (a) The Bayesian estimators were more likely to misclassify examinees into an inward ca…
The Holocene vegetation history of Lake Erhai, Yunnan province southwestern China
Open AccessJi Shen, Richard T Jones et al.ARTICLEThe Holocene2006Cited by: 10References: 6
A pollen diagram from a 6.62 m sediment sequence in Lake Erhai in northwest Yunnan, China was obtained to examine the roles of climate change and human impact on the development of the Erhai lake-catchment system since 12950 cal. yr BP. The record extends back into the Younger Dryas, where the dominance of Betula and deciduous Quercus points to a relatively cold and wet winter climate. After 11 750 cal. yr BP, a warming climate coupled with enhan…
