Communicating intent to develop shared situation awareness and engender trust in human-agent teams

This paper addresses issues related to integrating autonomy-enabled, intelligent agents into collaborative, human-machine teams. Interaction with intelligent machine agents capable of making independent, goal-directed decisions in human-machine teaming operations constitutes a major change from traditional human-machine interaction involving teleoperation. Communicating the machine agent’s intent to human counterparts becomes increasingly important as independent machine decisions become subject to human trust and mental models. The authors present findings from their research that suggest existing user display technologies, tailored with context-specific information and the human’s knowledge level of the machine agent’s decision process, can mitigate misperceptions of the appropriateness of agent behavioral responses. This is important because misperceptions on the part of human team members increases the likelihood of trust degradation and unnecessary interventions, ultimately leading to disuse of the agent. Examples of possible issues associated with communicating agent intent, as well as potential implications for trust calibration are provided.     

Visual knowledge discovery and machine learning for investment strategy

Knowledge discovery is an important aspect of human cognition. The advantage of the visual approach is in opportunity to substitute some complex cognitive tasks by easier perceptual tasks. However for cognitive tasks such as financial investment decision making this opportunity faces the challenge that financial data are abstract multidimensional and multivariate, i.e., outside of traditional visual perception in 2D or 3D world. This paper presents an approach to find an investment strategy based on pattern discovery in multidimensional space of specifically prepared time series. Visualization based on the lossless Collocated Paired Coordinates (CPC) plays an important role in this approach for building the criteria in the multidimensional space for finding an efficient investment strategy. Criteria generated with the CPC approach allow reducing/compressing space using simple directed graphs with beginnings and the ends located in different time points. The dedicated subspaces constructed for time series include characteristics such as Bollinger Band, difference between moving averages, changes in volume etc. Extensive simulation studies have been performed in learning/testing context. Effective relations were found for one-hour EURUSD pair for recent and historical data. Also the method has been explored for one-day EURUSD time series n 2D and 3D visualization spaces. The main positive result is finding the effective split of a normalized 3D space on 4 × 4 × 4 cubes in the visualization space that leads to a profitable investment decision (long, short position or nothing). The strategy is ready for implementation in algotrading mode.     

句法加工中的预测现象及实验证据

句法加工是读者通过整合输入的言语信息来理解句子的过程。句法加工的存在,使得读者能够提前预测文本的信息,提高阅读效率。由于阅读离不开信息整合,研究者提出两类不同的句法理论:句法预测的模块局域性理论和句法预测的互动分析性观点。这两类理论的争论点在于句法加工是单独模块化的自上而下加工,还是自下而上-自上而下的互动分析加工过程。其区别表现为句法预测的作用——前者认为句法预测对句子加工有抑制作用,后者认为句法预测对句子加工起促进作用。来自眼动、ERP等研究的数据佐证了句法预测的存在。未来研究应围绕其差异进行深入探讨,以揭示句法加工的实质。     

风险认知中的信任机制：对称或不对称？

上世纪90年代研究者开始研究信任的“不对称性原则”,即失去信任比得到信任容易。十余年来,不同研究者从信息类型、灾害类型以及先前态度等方面对信任的“不对称性原则”展开了继续探索,认为信任的“不对称性原则”是有条件的。另有一部分研究者直接从信任的结构对“不对称性原则”进行了反驳,认为信任应该包括社会信任和信心,社会信任基于共享的价值观,是对称的;信心基于客观的行为标准,是不对称的。信任研究应该针对社会信任这一维度。之所以会出现“不对称”或“对称”的矛盾,主要是由于信任结构的不一致。前者将信任看成是一维的,而后者认为信任是二维的。这就推动了信任的理论结构探索和启发式研究。通过对信任机制的研究,风险管理者和专家能够在实际的风险管理中制定相应的提高公众信任的措施,推动科技发展,提高生活质量,提升风险管理。     

The vigilant parent: Parental role salience affects parents' risk perceptions, risk-aversion, and trust in strangers

Since parenting involves protecting children from various risks and dangers, tendencies towards increased risk perception, risk-averse decision-making, and distrust of strangers may come to be associated with the parental role. Consequently, parents may be more likely to exhibit each of these psychological tendencies when their parental role is situationally salient than when it is not salient. We tested this hypothesis in two studies that manipulated the salience of the parental role in samples of parents and nonparents and measured the effects on participants' risk perceptions, risk-aversion, and trust in strangers. As we hypothesized, parents perceived greater risk (Study 1), made more risk averse choices (Study 1), and trusted strangers less (Study 2) when their parental role was salient than when it was not salient. Implications for understanding psychological adaptations to social roles are discussed.     

Motivations for promotion and prevention and the role of trust and commitment in interpersonal forgiveness

Granting forgiveness demands self-regulation. Distinct modes of self-regulation might therefore produce distinct routes to forgiveness. Self-regulation focused on advancement (or promotion) could motivate forgiveness through the perceived benefits to be attained by repairing a relationship, i.e., one’s trust that a partner will provide such benefits rather than further betrayal. In contrast, self-regulation focused on security (or prevention) could motivate forgiveness through the perceived costs of further relationship deterioration, i.e., one’s commitment to maintain a relationship upon which one depends and protect against the loss of this relationship. These hypotheses were supported across two studies that: (a) measured and manipulated promotion-focused versus prevention-focused self-regulation, (b) included real and imagined offenses in casual and close relationships, and (c) assessed forgiveness immediately following an offense and after a two-week delay. Trust in a relationship partner more strongly predicted forgiveness among promotion-focused individuals, whereas commitment to this partner more strongly predicted forgiveness among prevention-focused individuals.     

How communication increases interpersonal cooperation in mixed-motive situations

Evidence from two experiments indicates that task-related communication promotes cooperation in mixed-motive situations by activating interpersonal norms related to fairness and trust. In Experiment 1, task-related communication increased cooperation between individuals in a three-choice prisoner’s dilemma game (PDG-Alt) but task-unrelated communication did not. In Experiment 2, cooperation was increased both by sending a task-related message to one’s counterpart and receiving a cooperative task-related message from one’s counterpart. Mediation analyses revealed that task-related communication increased cooperation by activating fairness and trust norms (Experiments 1 and 2). Specifically, whereas sending (relative to receiving) a task-related message increased cooperation by activating fairness norms, receiving (relative to sending) a task-related message increased cooperation by activating trust norms (Experiment 2).     

Social reconnection revisited: The effects of social exclusion risk on reciprocity,trust, and general risk-taking

We hypothesize that people at risk of exclusion from groups will engage in actions that can socially reconnect them with others and test the hypothesis in four studies. We show that participants at risk of exclusion reciprocated the behavior of an unknown person (Study 1a) and a potential excluder (Study 1b) more compared to two control groups (people who received a non-social negative feedback and people who were actually excluded). Study 2 replicated the results of Study 1a with trust as the dependent variable. Study 3 showed that people who were at risk of exclusion took less general risk compared with both control groups. These results demonstrate socially adaptive responses of people who are at risk of social exclusion.     

Social rank, interpersonal trust and recall of parental rearing in relation to homesickness

This study set out to explore the relationship between recall of parental rearing, social rank, interpersonal trust and homesickness. Eighty-nine first year undergraduates (59 women and 30 men) living away from home and attending the University of Derby completed a set of questionnaires in their sixth week in the first semester at university. Results indicate that recall of supportive parenting is associated with lower homesickness, favourable social rank and greater interpersonal trust. Conversely, recall of parental rejection correlated with great homesickness, feeling inferior to others, and lower interpersonal trust. Two separate multiple regression analyses revealed that both the parental rearing variables, and the social rank and interpersonal trust variables, produced significant models in the prediction of homesickness scores. Mediation analysis suggests that whilst recalling one’s parents as rejecting is directly associated with increased homesickness, it may also generate feelings of inferiority that may lead to distress when moving into new environments.
