Mind-reading without the scanner: Behavioural decoding of working memory content

ABSTRACT

Sophisticated machine learning algorithms have been successfully applied to functional neuroimaging data in order to characterize internal cognitive states. But is it possible to “mind-read” without the scanner? Capitalizing on the robust finding that the contents of working memory guide visual attention toward memory-matching objects, we trained a multivariate pattern classifier on behavioural indices of attentional guidance. Working memory representations were successfully decoded from behaviour alone, both within and between individuals. The current study provides a proof-of-concept for applying machine learning techniques to simple behavioural outputs (e.g., response times) in order to decode information about specific internal cognitive states.     

Koran reading and negotiation with jinn: strategies to deal with mental ill health among Swedish Somalis

In this paper, we discuss traditional Somali concepts of mental ill health. Qualitative interviews were conducted with some 20 Swedish Somali interviewees about factors causing mental ill health, traditional classification, strategies to deal with mental ill health, and attitudes to the mental health care services in Sweden. Social mobilisation and religious healing are cornerstones of traditional Somali measures to deal with mental suffering. Traditional Somali views of mental ill health stand in stark contrast to classification of mental ill health in the western biomedical model. These views deserve attention since they may have an impact on health-seeking behaviour among Somali immigrants in western countries. Yet a too strong focus on cultural aspects may over-shadow the fact that much mental suffering among Somali migrants must be understood within social, economic, and political contexts.     

Merit,fit, and basic desert

Basic desert is central to the dispute between compatibilists and incompatibilists over the four-case manipulation argument. I argue that there are two distinct ways of understanding the desert salient to moral responsibility; moral desert can be understood as a claim about fitting responses to an agent or as a claim about the merit of the agent. Failing to recognize this distinction has contributed to a stalemate between both sides. I suggest that recognizing these distinct approaches to moral desert will help clarify a central source of disagreement between compatibilists and incompatibilists and assist both sides in resolving the current stalemate.     

Sport and the obligation of solidarity

The paper departs from an analysis of the case of Michelle Dumaresq, a transgender female downhill mountain biker who experienced marginalization within her sport. The analysis is based on Axel Honneth’s theory of recognition. The Dumaresq case is particularly relevant to Honneth’s ideas of solidarity, which provide insight into the dynamics of social integration. Honneth’s theory of recognition also provides a conceptual framework and a methodology that gives new perspectives on the ethical significance of sport. In the paper, an analysis is presented of the lack of solidarity experienced by Dumaresq. The argument is made that sport has a particular potential for realizing solidarity among its practitioners. Realizing solidarity however depends to a large degree upon that the rules of sport are perceived as fair and just. In the Dumaresq case, challenges to solidarity came from what her competitors considered to be unfair classification rules. Summing up, it is argued that, as long as the rules of a sport is perceived as fair and just, voluntary engagement gives rise not only to obligations on fair play but to a moral obligation on solidarity as well.     

易学的推类逻辑

易学中的逻辑问题,是一个在易学和逻辑学研究中被忽视的问题,但又是一个关系到对中国文化史、思想史和逻辑史的再认识的重要问题。易学中的逻辑是推类逻辑,本文给出了理由,同时以现代逻辑的方法给出了易学推类逻辑的形式系统,并作了讨论。指出易学逻辑是在中国文化背景下的以汉字表述的特有逻辑形式,建立了中国古代的普遍语言,形成了自我满足的语义系统,其在为人们提供正确的认识方法和为古代科学提供认识工具方面与西方逻辑是一致的。     

Age and Education Differences in Marriages and their Effects on Life Satisfaction

Within marriages husbands typically tend to be older and higher educated than their wife. This paper tries to explain this by analyzing whether age and education differences between spouses have an effect on happiness. Two alternative hypotheses are tested on the relation between age and education gaps between partners and life satisfaction. It is found that a positive age gap between husband and wife increases both male and female life satisfaction, while female life satisfaction increases if the education gap is smaller.

Do incompatible arguments cause extensive processing in the evaluation of arguments? The role of congruence between argument compatibility and argument quality

Previous studies have demonstrated that arguments incompatible with prior beliefs are subjected to more extensive refutational processing, scrutinized longer, and judged to be weaker than arguments compatible with prior beliefs. However, this study suggests whether extensive processing is implemented when evaluating arguments is not decided by argument compatibility, but by congruence between two evaluating tendencies elicited by both argument compatibility and argument quality. Consistent with this perspective, the results of two experiments show that relative to congruent arguments, participants judged arguments eliciting incongruent evaluating tendencies as less extreme in strength, spent more time, and felt more hesitant generating strength judgments for them. The results also show that it is mainly incongruent arguments, not congruent arguments, whose strength ratings were more closely associated with the perceived personal importance of the issue, which intensified the tendency to evaluate arguments depending on argument compatibility. These results suggest that it is the incongruity between argument compatibility and argument quality, and not simply the argument compatibility, that plays a more important role in activating an extensive processing in the evaluation of arguments.     

Judging the plausibility of arguments in scientific texts: a student–scientist comparison

The ability to evaluate scientific claims and evidence is an important aspect of scientific literacy and requires various epistemic competences. Readers spontaneously validate presented information against their knowledge and beliefs but differ in their ability to strategically evaluate the soundness of informal arguments. The present research investigated how students of psychology, compared to scientists working in psychology, evaluate informal arguments. Using a think-aloud procedure, we identified the specific strategies students and scientists apply when judging the plausibility of arguments and classifying common argumentation fallacies. Results indicate that students, compared to scientists, have difficulties forming these judgements and base them on intuition and opinion rather than the internal consistency of arguments. Our findings are discussed using the mental model theory framework. Although introductory students validate scientific information against their knowledge and beliefs, their judgements are often erroneous, in part because their use of strategy is immature. Implications for systematic trainings of epistemic competences are discussed.     

Human factors of transitions in automated driving: A general framework and literature survey

The topic of transitions in automated driving is becoming important now that cars are automated to ever greater extents. This paper proposes a theoretical framework to support and align human factors research on transitions in automated driving. Driving states are defined based on the allocation of primary driving tasks (i.e., lateral control, longitudinal control, and monitoring) between the driver and the automation. A transition in automated driving is defined as the process during which the human-automation system changes from one driving state to another, with transitions of monitoring activity and transitions of control being among the possibilities. Based on ‘Is the transition required?’, ‘Who initiates the transition?’, and ‘Who is in control after the transition?’, we define six types of control transitions between the driver and automation: (1) Optional Driver-Initiated Driver-in-Control, (2) Mandatory Driver-Initiated Driver-in-Control, (3) Optional Driver-Initiated Automation-in-Control, (4) Mandatory Driver-Initiated Automation-in-Control, (5) Automation-Initiated Driver-in-Control, and (6) Automation-Initiated Automation-in-Control. Use cases per transition type are introduced. Finally, we interpret previous experimental studies on transitions using our framework and identify areas for future research. We conclude that our framework of driving states and transitions is an important complement to the levels of automation proposed by transportation agencies, because it describes what the driver and automation are doing, rather than should be doing, at a moment of time.
