采用一套心理计量测验考察中美两国青老年被试在算术能力、知觉速度及空间方位能力方面的操作是否有国家间和年龄组间差异,不同领域之间是否有不同的能力模式。测验结果表明:在知觉速度和空间方位测验上,中美青年组的操作成绩均明显超过老年组;在算术能力测验上,中国青年组的成绩仍超过老年组,但美国青老年组间则无明显差异;中国青年组在算术能力测验上成绩优于美国同龄组,在其它两个测验上则无明显差异;在所有能力测验上中美老年组的成绩都无明显差异;总的模式表明,美国青年的算术能力呈逐代下降趋势,中国儿童和青年的算术能力远远超过美国同龄人的状况可能只是个近期的现象。 相似文献

通过总结人类问题求解的特点,我们提出了问题求解的一种中转站系统框架。本文采用口语报告分析所进行的研究表明该框架是一种问题求解方面的知识结构和有效的启发式求解策略。实验证明了次序性、熟悉性、类似性和系统控制性是决定求解能力和效率的关键因素。说明了中转站及其排序、强规则和弱规则及其相互配合、以及中转站系统的控制策略在较大程度上反映和模拟了人在求解复杂的专门问题时的知识结构和控制过程。 相似文献

Five different ability estimators—maximum likelihood [MLE ()], weighted likelihood [WLE ()], Bayesian modal [BME ()], expected a posteriori [EAP ()] and the standardized number-right score [Z ()]—were used as scores for conventional, multiple-choice tests. The bias, standard error and reliability of the five ability estimators were evaluated using Monte Carlo estimates of the unknown conditional means and variances of the estimators. The results indicated that ability estimates based on BME (), EAP () or WLE () were reasonably unbiased for the range of abilities corresponding to the difficulty of a test, and that their standard errors were relatively small. Also, they were as reliable as the old standby—the number-right score. 相似文献

The purpose of this paper is to give an explication of the concept of health which does not rely on the concept of disease. The explication is informed by a view of the human individual as an acting subject and it therefore places the abilities of agents in the centre. Abilities may be qualified in different ways. The qualification essential for understanding the dimension of health and illness relates abilities to environmental circumstances and high-ranking projects in the life plan. For this purpose generalized adaptedness is introduced as the overarching construction. The dimension of health and illness is characterized in terms of the adequacy of the repertoire for generalized adaptedness. Some immediate consequences concerning the notion of care are noted. 相似文献

以矩阵填充任务为材料,以眼动仪为研究工具,以3~6年级学生为被试,探讨图形推理中儿童推理过程的特征和策略使用的差异,以及推理能力高低组儿童完成图形推理任务的眼动模式差异.在本实验条件下,得出以下结论:(1)8岁以上儿童已经具备解决矩阵填充任务的逻辑思维能力,但高低水平组儿童在解决任务的能力水平上存在差异,高水平儿童的反应时较快、正确率较高;(2)在儿童推理的过程中,不同维度对推理过程的影响存在一定的层次:对形状、颜色维度的识别最容易,对大小维度的识别次之,对方向维度的识别最难;(3)高低水平组儿童获得策略的时间进程不同,差异主要产生在推理开始后的5~11秒这个阶段,在这一阶段中,高水平组儿童对方向这一较难维度的识别和正确答案的识别都快于低水平组儿童,体现了高水平组儿童更强的信息加工能力. 相似文献

采用LLTM作测量与认知结合研究的初步探讨 总被引:7,自引:1,他引:6
心理测量学与认知心理学相结合是新型测验理论和测验设计的核心思想。这两者的结合需要理论证实的认知加工模型和基于现代测验理论之上的测量模型,本文以空间认知能力的加工过程为例,通过心理学的实证研究,探索了心理测量学与认知心理学相结合的切入点及理论模型。 相似文献

Individuals may differ in their ability to learn the significance of emotional cues within a specific context. If so, trait emotional intelligence (EI) may be associated with faster cue learning. This study (N = 180) tested whether trait EI predicts faster learning of a critical cue for discriminating “terrorists” from “non-terrorists”, using virtual-reality heads as stimuli. The critical cue was either facial emotion (positive or negative), or a neutral feature (hat size). Cognitive ability and subjective state were also assessed. Participants were faster to learn with an emotive cue. Surprisingly, high trait EI was correlated with poorer performance, especially early in learning. Subjective distress was also associated with impaired learning to emotive cues. 相似文献

为明确同伴依恋与手机成瘾的关系及其机制,本研究构建了一个有调节的中介模型,重点考察了消极情绪的中介作用以及独处能力的调节作用。采用问卷法,对729名初中生的同伴依恋、消极情绪、独处能力及手机成瘾的情况进行调查。结果显示:(1)在控制性别、年龄、年级、是否独生、手机使用年限后,同伴依恋对手机成瘾具有显著的负向预测作用;(2)消极情绪在同伴依恋与手机成瘾的关系中起完全中介作用;(3)同伴依恋对手机成瘾的直接作用及消极情绪的中介作用均会受到独处能力的调节。研究结果不仅有利于从依恋理论及客体关系理论的视角理解同伴依恋与手机成瘾的内在机制,而且对引导初中生形成良好人际关系为其心理社会功能服务具有启示意义。 相似文献

Executive functions (EFs) and intelligence (IQ) are phenotypically correlated. In twin studies, latent variables for EFs and IQ display moderate to high heritability estimates; however, they show variable genetic correlations in twin studies spanning childhood to middle age. We analyzed data from over 11,000 children (9- to 10-year-olds, including 749 twin pairs) in the Adolescent Brain Cognitive Development (ABCD) Study to examine the phenotypic and genetic relations between EFs and IQ in childhood. We identified two EF factors—Common EF and Updating-Specific—which were both related to IQ (rs = 0.64–0.81). Common EF and IQ were heritable (53%–67%), and their genetic correlation (rG = 0.86) was not significantly different than 1. These results suggest that EFs and IQ are phenotypically but not genetically separable in middle childhood, meaning that this phenotypic separability may be influenced by environmental factors. 相似文献

In this study, mental rotation performance was assessed in both an object-based task, human figures and letters as stimuli, and in an egocentric-based task, a human figure as a stimulus, in 60 older persons between 60 and 71 years old (30 women, 30 men). Additionally all participants completed three motor tests measuring balance and mobility. The results show that the reaction time was slower for letters than for both human figure tasks and the mental rotation speed was faster over all for egocentric mental rotation tasks. Gender differences were found in the accuracy measurement, favoring males, and were independent of stimulus type, kind of transformation, and angular disparity. Furthermore, a regression analysis showed that the accuracy rate for object-based transformations with body stimuli could be predicted by gender and balance ability. This study showed that the mental rotation performance in older adults depends on stimulus type, kind of transformation, and gender and that performance partially relates to motor ability. 相似文献
