Cognitive solutions for security and cryptography

This paper describes the new security solutions based on cognitive approaches and new computing paradigm called cognitive cryptography. This new security area establish a new generation of computational methods and security systems, focused on creation intelligent cryptographic algorithms and security protocols using cognitive information processing approaches. Such systems are designed for semantic evaluation of encrypted data, and allow to select the most appropriate techniques of its encryption. This paper presents a possible application of such techniques for different security tasks like authentication, secret sharing, secure data management etc. Additionally, some cryptographic solutions inspired by biological models will be presented.     

What types of advice do decision-makers prefer?

In the decision-making literature, “advice” has typically been defined very restrictively, as a recommendation concerning which alternative the decision-maker should choose. The present paper examines decision-makers’ reactions to this and three additional types of advice (a recommendation concerning which alternative not to choose, information about alternatives, and a recommendation concerning how to make the decision), along with another common form of interpersonal assistance (Social Support), from the perspective of maximizing decision accuracy and maintaining decision autonomy. The role of situational and individual differences is also examined. Results from two multilevel policy-capturing studies indicate that, although they consider recommendations regarding which alternative to choose to be important in some contexts, decision-makers often prefer to receive a type of advice that is greatly understudied by researchers—namely, the provision of information about alternatives. The implications of these findings for the study of advice-taking are discussed, as are future research directions.     

PASS理论语境中的认知过程(英文)

计划-注意-同时性加工-继时性加工,这些基本PASS概念的提出,是为了给传统上将智力作为一个笼统构念的做法提供某种替代的选择。在这一新的理论途径中,我将一般能力分解为对主要认知过程的研究,其中每个认知过程均有其行为、认知和神经心理成分,而且重要的是,每个认知过程均有相应的一组评估测量任务。PASS模型,这一理论框架能够充分包容体现于教育和组织行为中的广泛一系列认知功能。     

罗夏综合系统的元分析*

为考察罗夏墨迹测验Exner综合系统常模的客观性和准确性,运用元分析的方法,将来自16个国家的18篇罗夏综合系统正常成人的研究结果,与Exner新版常模进行比较。结果显示,在综合系统的全部113个变量中,有23个变量在联合样本与Exner常模间存在显著差异,包括被试的资源、能力、认知水平和人际关系等方面,且均为Exner常模样本结果更加优秀。结论:新版罗夏综合系统常模具有一定的偏差,存在偏好倾向,使用时应注意避免对被试的低估甚至做出假阳性的诊断。     

From BIS/BAS to the big five

Gray ( 1987 ) proposed two systems that underlie much of our behaviour and personality. One system relates to avoidance or withdrawal behaviour, called the Behavioural Inhibition System (BIS), whereas the other system relates to approach behaviour, called the Behavioural Approach System (BAS). In two samples, it was investigated whether individual differences in surface of personality as described by the Big Five can be explained by BIS/BAS. Neuroticism and Extraversion could be explained well by BIS/BAS, but also for Agreeableness and Conscientiousness consistent findings were obtained. Copyright © 2006 John Wiley & Sons, Ltd.     

Drivers’ attitudes toward imperfect distraction mitigation strategies

Studies were conducted to assess driver acceptance of and trust in distraction mitigation strategies. Previous studies have shown that in-vehicle tasks undermine driver safety, and that there is a need for strategies to reduce the effects of in-vehicle distractions. Trust and acceptance of such strategies strongly influence their effectiveness. Different strategies intended to reduce distraction were categorized in a taxonomy. Focus groups were conducted to help refine this taxonomy and explore driver acceptance issues related to these strategies. A driving simulator experiment was then conducted using two of the strategies: an advising strategy that warns drivers of potential dangers and a locking strategy that prevents the driver from continuing a distracting task. These strategies were presented to 16 middle-aged and 12 older drivers in two modes (auditory, visual) with two levels of adaptation (true, false). Older drivers accepted and trusted the strategies more than middle-aged drivers. Regardless of age, all drivers preferred strategies that provided alerts in a visual mode rather than an auditory mode. When the system falsely adapted to the road situation, trust in the strategies declined. The findings show that display modality has a strong effect on driver acceptance and trust, and that older drivers are more trusting and accepting of distraction mitigation technology even when it operates imperfectly.     

Improving Independence of Elderly People by Introducing Smart Products: The Guide Me Localization Case

What are the potential benefits of introducing technological innovations when working on issues with a wider societal impact? Focusing on a specific care and housing corporation for elderly people, the Sustainable System Innovation process has been used to translate an innovation challenge on macro societal level: “How can we deal with the challenges that occur due to the aging of society?” to a concrete innovation challenge on microtechnological and user level: “How can a tracking device be designed for optimal use by elderly person and care giver?”     

New Developments in Understanding Emotional Facial Signals in Chimpanzees

ABSTRACT— There has been little research over the past few decades focusing on similarities and differences in the form and function of emotional signals in nonhuman primates, or whether these communication systems are homologous with those of humans. This is, in part, due to the fact that detailed and objective measurement tools to answer such questions have not been systematically developed for nonhuman primate research. Despite this, emotion research in humans has benefited for over 30 years from an objective, anatomically based facial-measurement tool: the Facial Action Coding System (FACS). In collaboration with other researchers, we have now developed a similar system for chimpanzees (ChimpFACS) and, in the process, have made exciting new discoveries regarding chimpanzees' perception and categorization of emotional facial expressions and similarities in the facial anatomy of chimpanzees and humans, and we have identified homologous facial movements in the two species. Investigating similarities and differences in primate emotional communication systems is essential if we are to understand unique evolutionary specializations among different species.

Priming meritocracy and the psychological justification of inequality

The belief that status in society is based on merit is a central feature of the American Dream. This belief system justifies status inequalities by locating the cause of status differences in the individual talents and efforts of group members. We hypothesized that activating meritocratic beliefs increases the extent to which individuals psychologically justify status inequalities, even when those inequalities are disadvantageous to the self. Specifically, we hypothesized that priming meritocracy prompts individuals to engage in system-justifying psychological responses when they experience threat either at the personal or group level. Across two studies, priming meritocracy led members of a low status group to justify both personal and group disadvantage by decreasing perceptions of discrimination (Studies 1 and 2) and increasing the extent to which they stereotyped themselves and their group in status-justifying ways (Study 2).
