A robust vision-based method for staircase detection and localization

A robust vision-based staircase identification method is proposed, which comprises 2D staircase detection and 3D staircase localization. The 2D detector pre-screens the input image, and the 3D localization algorithm continues the task of retrieving geometry of the staircase on the reported region in the image. A novel set of principal component analysis-based Haar-like features are introduced, which extends the classical Haar-like features from local to global domain and are extremely efficient at rejecting non-object regions for the early stages of the cascade, and the Viola–Jones rapid object detection framework is improved to adapt the context of staircase detection, modifications have been made on the scanning scheme, multiple detections integrating scheme and the final detection evaluation metrics. The V-disparity concept is applied to detect the planar regions on the staircase surface and locate 3D planes quickly from disparity maps, and then, the 3D position of staircase is localized robustly. Finally, experiments show the performance of the proposed method.     

Visual attribute modulates the time course of iconic memory decay

Studies on iconic memory demonstrate that rich information from a visual scene quickly becomes unavailable with the passage of time. The decay rate of iconic memory refers to the dynamics of memory availability. The present study investigated the iconic memory decay of different stimulus attributes that comprised an object. Specifically, in Experiment 1, participants were presented with eight coloured numbers (e.g., red 4) and required to remember only one attribute, either colour or number, over different blocks of trials. The participants then reported the cued attribute in which the cue Stimulus Onset Asynchrony (SOA) from the memory array onset was varied (0, 100, 200, 300, 500, and 1000?ms). We found that numerical information became unavailable more quickly than colour information, despite the fact that the memory accuracies at 0 and 1000?ms SOAs were comparable between the two attributes. In Experiment 2, we replicated the finding that a numerical representation was lost more quickly than a colour representation when visual masks followed the target stimulus. These results suggest that the various visual attributes comprising an object are lost over time at different rates in iconic memory. We discuss this finding in relation to how perceptual representation is transferred to the capacity-limited visual working memory.     

Relationships Between Social Support,Internal Assets,and Life Satisfaction in Korean Adolescents

In previous literature, social support has been reported to have a significant, positive relationship with life satisfaction. However, few studies have examined this relationship among Korean youths and how their psychological functioning is associated with both social support and life satisfaction. This study investigated the associations between different sources of social support (i.e., family, peer, and teacher), psychological factors (i.e., self-efficacy and emotional regulation), and life satisfaction, in a sample of 1133 Korean adolescents. The possibility of sex differences in these relationships was also investigated. Results indicated that only family support had a direct relationship with life satisfaction for male adolescents; however, all three types of social support were found to have a significant, indirect relationship with life satisfaction for male adolescents through both psychological factors. In contrast, all three types of social support had a direct relationship with life satisfaction of female adolescents. Additionally, self-efficacy had a mediating effect on the relationship between the social support from family and teachers and life satisfaction of female adolescents. The results and implications of the study are discussed.     

建构反应题中能力估计准确性的影响因素:评分者人数和项目个数的交互作用

采用康春花、孙小坚和曾平飞(2016)提出的等级反应多水平侧面模型探讨了评分者人数和项目个数对被试能力估计准确性的影响。模拟研究的结果表明:(1)随着项目个数的增加,估计值与真值之间的相关也不断增加;(2)评分者人数和项目个数在平均绝对偏差(MAB)和误差均方根(RMSE)上的主效应均显著,两者间的交互效应也显著;(3)简单效应分析发现,当项目较少时,3个评分者条件下的能力估计准确性最好; 随着项目个数的增加,4个评分者的估计误差迅速下降,且表现变为最好。     

Are Decisions Made by Group Representatives More Risk Averse? The Effect of Sense of Responsibility

We tested the hypothesis that a sense of responsibility drives group representatives' decisions to be more risk averse compared with decisions made by individuals. The hypothesis was supported when the monetary considerations (i.e., payoff inequality and the magnitude effect) were controlled for in the potential gain domain as well as in the potential loss domain. Evidence showed that this is because the group representatives were concerned about how they would view themselves (e.g., guilt and self‐blame) and also how they would be viewed by others (i.e., to avoid being blamed and looked down upon by others). This study provided new insights into understanding group representatives' decision making under risk. Copyright © 2017 John Wiley & Sons, Ltd.     

3～6岁儿童人格发展的群组序列追踪研究

目的:运用自编幼儿人格发展教师评定问卷对幼儿人格进行追踪测量,探讨其年龄及性别发展特点。方法:用整群抽样法选取3~3.5岁、3.5~4岁、4~4.5岁3个年龄群组幼儿为被试,采用群组序列的追踪设计,进行为期1年半的追踪测量,结合潜变量增长曲线模型和多层线性模型处理数据,探讨幼儿在3~6岁间人格的发展特点。结果:(1)幼儿的智能特征、认真自控、外倾性、亲社会性、情绪稳定性5个人格维度在3~4岁发展最快,4~5岁持续增长但发展速度放缓,到5~6岁时趋于平稳;(2)女孩的认真自控和亲社会性在3岁时显著高于男孩,但在3~6岁间的增长率不存在差异,即女孩的认真自控和亲社会性在幼儿阶段发展水平始终高于男孩。结论:从家庭进入幼儿园的环境变迁促使了幼儿人格的进一步发展,5岁左右幼儿人格开始初步形成;女孩的认真自控和亲社会性水平在幼儿阶段始终高于男孩。     

Vocational Personality Traits in Counselor Education and School Psychology Students

We assessed the vocational personality of 104 graduate students in school counseling, mental health counseling, and school psychology programs using Holland's ( 1997 ) theory of personality and career choice. The correlational findings confirmed the importance of vocational personality traits in relation to the academic performance of graduate students. Among the Self‐Directed Search–Revised vocational personality types, the Investigative type emerged as a consistent predictor of performance on all sections of the Graduate Record Examination. The participants from 3 graduate programs predominantly identified Social as their primary vocational personality type, with variability in the secondary and tertiary code positions. The student group with the highest degree of congruence, defined as the degree of fit between one's personality and the environment, had the highest graduate grade point average, indicating the relationship between the degree of congruence and achievement. Theoretical and practical implications of the findings are discussed.     

Helping Peers Seek Professional Treatment for Depression Among Young South Koreans: An Application of the Theory of Planned Behavior

This study examined the applicability of the theory of planned behavior to understand factors that influence whether young South Koreans help peers with depression to seek professional counseling services. The structural equation modeling on the survey data collected from 191 South Korean students suggests that subjective norms and behavioral control could be salient factors for young South Koreans to take initiative and assist their peers in need of counseling services. Este estudio examinó la aplicabilidad de la teoría del comportamiento planificado para comprender factores que influyen sobre la decisión de jóvenes surcoreanos de ayudar a sus compañeros que sufren de depresión a buscar ayuda profesional a través de servicios de consejería. El modelo de ecuación estructural de los datos de la encuesta recogidos de 191 estudiantes surcoreanos sugiere que las normas subjetivas y el control del comportamiento podrían ser factores destacados para los jóvenes surcoreanos a la hora de tomar la iniciativa y ayudar a sus compañeros que necesitan servicios de consejería.
