An item response theory analysis of the Impulsive Behaviors Checklist for Adolescents

This study used item response theory (IRT) to examine the Impulsive Behaviors Checklist for Adolescents (IBCL-A) among 6,276 (67.7% girls) Chinese secondary school students. The IBCL-A included 15 maladaptive impulsive behaviors adapted from the Revised Diagnostic Interview for Borderlines. The authors obtained the severity and discrimination parameters for each item in the IBCL-A, examined differential item functioning across gender and age groups, and tested reliability and concurrent validity of the IBCL-A IRT-scaled score. Most items in the IBCL-A were the most accurate in assessing moderate to high levels of impulsivity and discriminated well among adolescents with varied levels of impulsivity. Differential item functioning emerged in several items across gender. The IRT-scaled score showed good construct validity and incremental predictive validity. Findings demonstrate the sound psychometric properties of the IBCL-A and support the clinical utility of this scale.     

父母温暖与青少年情绪表达能力的关系:害羞和自尊的中介作用

采用父母教养方式问卷、情感交流能力测验(ACT)、Rosenberg自尊量表和害羞量表测量449名高中生。探讨害羞和自尊在父母温暖与青少年情绪表达能力之间的中介作用。结果表明:父母温暖与自尊和情绪表达能力均呈显著正相关、与害羞呈显著负相关;自尊与情绪表达能力呈显著正相关,而害羞与情绪表达能力呈显著负相关;自尊和害羞在父母温暖与情绪表达能力之间起部分中介作用。因此,父母温暖不仅可以直接影响青少年的情绪表达能力,也可以通过提高自尊或减少害羞进而有助于青少年情绪表达能力的发展。     

劝捐策略和框架效应对个体捐赠决策的影响

采用两个3×2完全随机实验设计,考察劝捐策略和目标框架效应对个体捐赠决策的影响,结果表明：（1）劝捐策略和目标框架效应的主效应显著,信用劝捐被试捐赠更多,决策时间更短,损失目标框架比收益目标框架的被试决策时间更短,捐赠更多,被试在信用X损失框架情境中捐赠最多,反应时最短;（2）劝捐策略和框架效应的交互效应均显著,情感策略受框架效应影响较大,在损失框架下被试反应时更短,捐赠更多。     

Perceived body size affected by garment and body mass index

This study investigated the effect of garment size on perceived body size. The perceived body sizes of nine Chinese men, with Body Mass Index between 17.0 and 37.1 kg/m(2), wearing five sizes of white T-shirts were assessed using Thompson and Gray's Nine-figural Scale. Garment sizes on perceived body sizes were different for those of different Body Mass Index. A backpropagation neural net model was used to model the nonlinear relationship between the perceived body size and the body's BMI, body chest girth, and garment ease (difference between garment and body chest girth). When the BMI was less than 20, wearing larger-sized T-shirts tended to increase perceived body size. For large chest sizes and for taller persons (BMI of 20 to 28) large garments made the wearer look thinner. However, for small persons (BMI of 20 to 28) effect of garment size was relatively small. Obese persons (BMI of > 28), wearing garments too tight or too loose were perceived as larger. Minimum perceived body size was found for garment ease of 2 to 3 cm.     

From recurrent choice to skill learning: a reinforcement-learning model

The authors propose a reinforcement-learning mechanism as a model for recurrent choice and extend it to account for skill learning. The model was inspired by recent research in neurophysiological studies of the basal ganglia and provides an integrated explanation of recurrent choice behavior and skill learning. The behavior includes effects of differential probabilities, magnitudes, variabilities, and delay of reinforcement. The model can also produce the violation of independence, preference reversals, and the goal gradient of reinforcement in maze learning. An experiment was conducted to study learning of action sequences in a multistep task. The fit of the model to the data demonstrated its ability to account for complex skill learning. The advantages of incorporating the mechanism into a larger cognitive architecture are discussed.     

不同ISI下异同判断的同反应启动效应

通过改变刺激对中的第一个刺激消失到第二个刺激出现之间的间隔 (interstimulusinterval,简称ISI) ,并控制呈现的刺激前后试验不重复 ,分别进行不同形状白色图形的异同判断实验和不同颜色圆形的异同判断实验 ,系统地考察不同ISI下异同判断的同反应启动效应 ,研究异同判断的加工机制。两个实验均采用 2 (前次试验类型 :异、同 )× 2 (当前试验类型 :异、同 )× 6(ISI :1 0 0ms、2 0 0ms、30 0ms、40 0ms、50 0ms、60 0ms)重复测量设计。被试为2 1名大学本科生 ,其中男生 1 0名 ,女生 1 1名。结果发现 ,在两实验中的每一种ISI条件下 ,同反应后的试验的反应时均显著短于异反应后的试验的反应时 ,即表现出显著的同反应启动效应。实验的结果支持异同判断的双过程模型 ,并表明双加工机制可能是序列工作的

Trust me if you can: The effect of driver username on passengers' intention to use ride-sharing service

Building trust and enhancing consumers' participation are critical for the growth of peer-to-peer sharing economy. This research explores the effect of driver username on passengers' intention to use ride-sharing service and its underlying psychological mechanisms. The results indicate that driver username has a significant impact on passengers' intention to use ride-sharing service, as a driver with a real name elicits greater intention to use ride-sharing service than a driver with a screen name (studies 1, 2, 3a, 3b, and 3c). In addition, the effect of driver username on passengers' intention to use ride-sharing service is serially mediated by social presence and trust (study 2). Importantly, the effect of driver username on passengers' intention to use ride-sharing service is moderated by driver reputation (studies 3a, 3b, and 3c). A high (vs. low) reputation facilitates the impact of driver username on passengers' usage intention. Based upon these findings, theoretical and practical implications are discussed.     

COVID-19 non-death loss and acceptance coping: A 3-wave cross-lagged panel analysis

Numerous individuals have lost loved ones during the COVID-19 pandemic while millions of others have also experienced ongoing pervasive non-death loss. The understanding of how people deal with non-death loss is still relatively limited. Incorporating theory of coping and loss, this study examines the reciprocal relationship between non-death loss and acceptance coping. Based on the results of a cross-lagged panel model involving 314 participants in China, we found that before the end of the zero-Covid policy, non-death loss at Time 1 predicted less acceptance coping at Time 2, but in the opening up stage in late 2022, non-death loss at time 2 did not predict acceptance coping at time 3. The findings have significant implications for understanding the interplay between non-death loss and acceptance coping and highlights abrupt psychological changes during the COVID-19 pandemic.     

Chinese Tourist Vacation Satisfaction and Subjective Well-being

While the effects of vacation on tourists have been frequently discussed in the Western context, research endeavors to understand such effects in a non-Western context are rather limited. The current study aimed at investigating Chinese tourists’ subjective well-being and its potential changes associated with vacation experiences. The survey of 302 Chinese tourists confirmed the positive effect of satisfaction with service aspects of travel/tourism phases on satisfaction with travel/tourism services, the positive effect of trip reflections and satisfaction with travel/tourism services on satisfaction with travel experiences, and the direct positive effect of satisfaction with travel experiences on travelers’ SWB. This study further explored the corresponding roles of travel duration and frequency. The results suggested a moderating effect of vacation duration on the link between tourist satisfaction and SWB; vacation frequency did not have such an effect. Theoretical and managerial implications of the findings were discussed, followed by recommendations for future research.
