时间记忆层次网络模型的实验检验

实验采用分类性实验材料,使被试在对词单项目加工时形成较清晰的群集,进而形成时间组块,目的在于对时间记忆层次网络进行直接检验。其中时序判断用反时间时和正确率两种反应指标,时距估计用再现和口头估计两种方法。结果发现,时间信息记忆既存在层次网络的特征,又存在线性结构的特征。     

Effects of the function-specific instruction approach to neurofeedback training on frontal midline theta waves and golf putting performance

A recent meta-analysis has shown inconclusive results on the effectiveness of traditional electroencephalography (EEG) neurofeedback training (NFT) protocols in changing EEG activity and improving sports performance. To enhance the effectiveness of EEG NFT protocols, we explored a new approach to EEG NFT, namely the function-specific instruction (FSI) approach. The basic tenet underpinning effective verbal instruction is to induce mental states as the verbal instructions consider the meaning of the brainwave function in the target region and the EEG power magnitude. This study aimed to test whether a single session of FSI is efficacious in improving frontal midline theta (FMT) activity and putting performance. Method: Thirty-six skilled golfers with a handicap of 14.05 ± 9.43 were recruited. A consecutive sampling method was used to form three groups: an FSI group (n = 12), a traditional instruction (TI) group (n = 12), and a sham control (SC) group (n = 12). In the pre- and post-tests, each participant performed 40 putts from a distance of 3 m, and the number of holed putts was recorded. The participants were asked to perform 50 trials in a single session of NFT. Putting performance improved significantly from before to after NFT in the FSI group. Moreover, the FSI group demonstrated a significant decrease in FMT power, whereas the SC group demonstrated a significant increase in FMT power from before to after NFT. These findings suggest that the FSI approach is more effective in enhancing sustained attention and putting performance in skilled golfers than TI.     

Behavior analysis and revaluation

Revaluation refers to phenomena in which the strength of an operant is altered by reinforcer-related manipulations that take place outside the conditioning situation in which the operant was selected. As an example, if lever pressing is acquired using food as a reinforcer and food is later paired with an aversive stimulus, the frequency of lever pressing decreases when subsequently tested. Associationist psychology infers from such findings that conditioning produces a response-outcome (i.e., reinforcer) association and that the operant decreased in strength because pairing the reinforcer with the aversive stimulus changed the value of the outcome. Here, we present an approach to the interpretation of these and related findings that employs neural network simulations grounded in the experimental analysis of behavior and neuroscience. In so doing, we address some general issues regarding the relations among behavior analysis, neuroscience, and associationism.     

基于系统动力学的群体情绪传播模型

选取某高校20个教学班级共计614人为被试,采用心理学实证与系统动力学（system of dynamic）与社会网络（social network）建模相结合的研究方法,对群体情绪传播的动力学规律进行了建模,并将模型仿真结果与心理实验结果进行了比对。结果表明,所建立的模型能够较好地刻画出群体情绪传播的动力学规律,具有较高的生态效度。该模型的建立对群体性事件的定量预警与监控提供了基础理论依据。     

道德直觉决策及其机制探析

道德直觉决策研究是从直觉思维角度探讨决策者在道德境遇下的决策。道德直觉决策是道德情境下的直觉反应, 其理论基础包括躯体标记假说、社会直觉模型、双加工理论、事件特征情感复合体系以及双系统理论; 道德直觉决策机制至少包括：无意识加工、情绪加工和直觉加工三个基本的心理加工过程, 与之对应的神经系统则至少存在三个可能的脑神经回路：无意识加工的道德脑区、情绪加工的道德脑区和直觉加工的道德脑区。研究主要从客观和主观两方面分析了道德直觉决策的一般性影响因素--文化、道德境遇、经验、情绪和道德直觉; 揭示了道德直觉决策的加工机制。未来研究应在加强理论建构的基础上, 通过更缜密细致的实验设计去探究决策过程中各因素的交互作用, 并明确道德脑区之间的联结。     

Sensitive Topics,Missing Data,and Refusal in Social Network Studies: An Ethical Examination

We describe our ethics‐driven process of addressing missing data within a social network study about accountability for racism, classism, sexism, heterosexism, cis‐sexism, ableism, and other forms of oppression among social justice union organizers. During data collection, some would‐be participants did not return emails and others explicitly refused to engage in the research. All refusals came from women of color. We faced an ethical dilemma: Should we continue to seek participation from those who had not yet responded, with the hopes of recruiting more women of color from within the network so their perspectives would not be tokenized? Or, should we stop asking those who had been contacted multiple times, which would compromise the social network data and analysis? We delineate ways in which current discussions of the ethics of social network studies fell short, given our framework and our community psychology (CP ) values. We outline literature that was helpful in thinking through this challenge; we looked outside of CP to the decolonization literature on refusal. Lessons learned include listening for the possible meanings of refusals and considering the level of engagement and the labor required of participants when designing research studies.     

On the nature of international sales and sales management research: a social network–analytic perspective

This research uses a combination of text mining, co-word analysis, and social network analysis (SNA) to review 132 international sales and sales management (ISSM) articles published between 1980 and 2017. The study provides a unique view of the past and future of ISSM research and provides three principal contributions. First, from a social network–analytic perspective, it offers a unique examination of the ways ISSM research topics are interconnected, as reflected by keyword network structure. Second, by conducting SNA across two periods (1980–1999 and 2000–2017) and examining the changes in network centrality measures, the study offers initial insights into the evolving nature of the ISSM literature. Third, the study reports keyword network disconnections (i.e., structural holes) to propose a fruitful agenda for future ISSM research. Taken together, this research offers a current perspective of the ISSM research domain's evolving nature.     

Differences in Beliefs About Psychological Services in the Relationship Between Sociorace and One's Social Network

The roles of previous psychological service use and social network variables in beliefs about psychological services were examined with 184 college students. Having friends and family members who used psychological services, being female, and having used psychological services positively related with beliefs about psychological services. Socioracial differences in the effects of previous use of psychological services and social network variables on students’ beliefs about psychological services were found. Suggestions for ways counselors can provide support to students are discussed.     

Selection of a Third‐Party Logistics Provider: Capturing the Interaction and Influence of Performance Metrics with the Analytical Network Process

When a business decides to outsource its logistics operations to improve its performance, the organization will need to select a third‐party logistics provider (3PL) that shares common goals and satisfies service level requirements. In this paper, we identify a set of 3PL performance measures from the perspective of the supply chain and organize them into a time‐phased format, beginning with the post production stage and continuing through the delivery of the goods to the customer distribution center. The supply chain flow is presented as a Metrics Arrow. To integrate the performance metrics (PM) into one model, we propose an analytical network process (ANP) to capture all PM and to understand the interrelated influences among them. Additionally, to derive the weights for PM, the proposed ANP model offers managerial insight into the relative impact of each metric as well as warning signals or trigger points within the network of PM. The model provides a realistic framework to choose the 3PL that can help achieve the greatest improvements within the supply chain. Copyright © 2012 John Wiley & Sons, Ltd.
