用微机化的伪随机点立体图对发生器产生静态和动态随机点立体图对(RDS),显示在左右两个示波器上。RDS图形中的元素密度可以改变。具有正常立体视的10名被试通过立体镜观察这些图形,测量双眼融合能产生完整立体图形感知所需最小的元素密度,即密度容限。 设计了三个实验用以检测改变RDS图形的空间参数对密度客限的影响。第一个实验,在静、动态RDS图形下,改变视差图形面积;第二个实验,改变视差图形的形状;第三个实验,改变视差图形的周长。 实验结果表明,双眼深度感知要求一定的元素密度容限,视差图形的大小和形状对密度容限有一定程度的影响。静态和动态RDS图形的密度容限也不相同。 本文利用RDS的整体立体感知特性和空间频率通道理论对实验结果进行了讨论。  相似文献

护士职业的人格特质研究   总被引:22,自引:1,他引:21  
采用Y-G性格测验问卷,对临床护士和在读护生共390人,进行了心理测评,展开了护士职业的人格特质研究。研究结果表明:优秀护士群体的性格类型和某些人格特质显著地优于一般护士群体;优秀护士与一般护士间所显现出显著差异的人格特质,对于护士角色人格的构成具有决定性影响;Y-G性格测验的A型性格类型评定对于护士职业的心理选拔显现特异性趋势;整个测评研究结果,基本支持"护士个体人格特质与角色人格特质的匹配模式"等理论假设.  相似文献

汉语阅读困难儿童认知特征研究   总被引:43,自引:2,他引:41  
为了解汉语阅读困难者的认知特征,本研究从967名5年级11-13岁学生中抽取了118名被试,将他们分成困难组(包括截点组和低成就组)和对照组,并将其在词语理解等8个认知变量上进行了比较。结果表明,图形记忆与加工能力及对词语和一般信息理解能力的缺损是汉语阅读困难者主要的认知特征。研究还表明,一般信息理解能力发展水平是区分一般阅读落后和特殊阅读落后的一个指标。  相似文献

To explore parenting style, child effortful control, parenting stress, and their associations with maternal use of pressure to eat among Asian U.S. immigrant families with preschoolers. One hundred and nine Asian immigrant mothers with 3-to-5-year-old children in Maryland, United States rated their authoritative and authoritarian parenting styles, frequency of pressuring their child to eat, perceived parenting stress, and child’s effortful control. Two proposed moderated mediation models were tested using conditional process modeling. Effortful control mediated the association between authoritative parenting style and pressure to eat practices, αβ?=??0.07, p?<?0.05, and the association between authoritarian style and pressure to eat, αβ?=?0.12, p?<?0.05. Moreover, parenting stress moderated the association between child effortful control and maternal pressure to eat in the authoritarian style model, but not in the authoritative style model. Specifically, higher effortful control was associated with less use of pressure to eat at low and mean levels of parenting stress. Our findings revealed potential mechanisms underlying the associations between parenting styles and controlling feeding practices. Importantly, information learned from the present study may guide transdisciplinary efforts to design and implement culturally sensitive and family-based interventions targeting Asian immigrants’ wellbeing and obesity in the United States.

To investigate the influence of the home environment, defined as family socioeconomic status (SES) (parent education level, household income), student resource-mediated SES (access to nutritional resources and cognitively stimulating experiences), reading ability, and difficulty with homework on quality of life in children and adolescents residing in urban and suburban areas in Hangzhou City, Zhejiang Province, China. This study included 3200 Grade 3–6 students from 8 elementary schools in Hangzhou City. Assessments included questionnaires that evaluated student quality of life, family SES, resource-mediated SES (dietary behavior and the home literacy environment), reading ability, and difficulty with homework. The effects of the home environment on student quality of life were analyzed by univariate analysis, multiple linear regression analysis, and structural equation modeling. Overall, 80.6% of students had a medium or better quality of life. Young age (Grade 3 or 4), female sex, household income of 10000–15000 RMB, high breakfast consumption, daily intake of fruit, a balanced diet, and good reading habits were positively correlated with student quality of life (P?<?0.05), while overuse of electronic devices was negatively correlated with quality of life (P?<?0.05). Dietary behaviors, home literacy environment, and student reading ability and difficulty with homework directly affected quality of life. Family SES indirectly affected student quality of life. Children and adolescents in China should have access to good nutrition and cognitively stimulating experiences to enhance their well-being and provide them with social and academic advantages.

Due to the outbreak of the COVID-19 pandemic, the implementation of quarantine policy led to an unprecedented home-quarantined living and online learning context for Chinese college students. This study aimed to investigate whether and how social support contributed to home-quarantined Chinese college students’ well-being during the COVID-19 pandemic. In particular, this study examined the mediating role of online learning self-efficacy in explaining how social support contributed to home-quarantined Chinese college students’ well-being. The study also examined the moderating effect of anxiety, which may buffer the effectiveness of social support and online learning self-efficacy in home-quarantined online learning contexts. Data include 2481 responses to an online questionnaire survey from home-quarantined Chinese college undergraduates. Data were analyzed by performing Partial Least Squares regression. Results showed that social support associated positively with home-quarantined Chinese college students’ online learning self-efficacy and well-being. The results revealed a partial mediating effect of online-learning self-efficacy on the positive effect of social support on well-being. The moderating effect analysis found that the positive association of online learning self-efficacy with social support and well-being was stronger in home-quarantined Chinese college students who perceived no anxiety.
