Common-sense reasoning as proto-scientific agent activity

We wish to model common-sense reasoning in situations where it contains some of the ingredients typical of proto-scientific reasoning, with a view to future elaboration and proof of concept. To model this proto-scientific narrative, we employ the integrative formal computational machinery we have been developing and implementing for rational cooperative epistemic agents. In our logic-based framework, agents can update their own and each other's theories, which are comprised of knowledge, active rules, integrity constraints, queries, abducibles, and preferences; they can engage in abductive reasoning involving updatable preferences; set each other queries; react to circumstances; plan and carry out actions; and revise their theories and preferences by means of concurrent updates on self and others.     

Mereotopological Connection

The paper outlines a model-theoretic framework for investigating and comparing a variety of mereotopological theories. In the first part we consider different ways of characterizing a mereotopology with respect to (i) the intended interpretation of the connection primitive, and (ii) the composition of the admissible domains of quantification (e.g., whether or not they include boundary elements). The second part extends this study by considering two further dimensions along which different patterns of topological connection can be classified – the strength of the connection and its multiplicity.     

分析性认知风格对偏差反应与冲突探查的影响

采用2Wingdings 2MC@2Wingdings 2MC@2混合设计和相关分析法,考察个体的分析性认知风格对其在完成有、无冲突的推理判断任务时的逻辑反应倾向和冲突探查过程的影响。结果表明分析性认知风格不会直接影响被试完成推理任务的逻辑反应倾向性,高、低分析性认知风格倾向组被试在逻辑反应正确率上不存在显著差异; 但对个体的冲突探查过程会有影响,高、低认知风格倾向组被试在反应自信率上存在显著差异,且冲突探查大小与分析性认知风格显著负相关,这一结果表明那些高分析性认知风格倾向的个体在完成冲突任务时,更可能探查到刻板反应与遵从逻辑规则做出的反应之间的冲突。     

Counterfeit Luxury Consumption in a Social Context: The Effects on Females’ Moral Disengagement and Behavior

What happens when females use counterfeit luxury products in a social context? The authors show that counterfeit users view social interactions they have with other people as a possible signal that their counterfeit product has been judged to be an authentic luxury product (high authenticity signal) or a counterfeit product (low authenticity signal). Low authenticity signals trigger higher levels of social anxiety than do high authenticity signals. And, higher levels of social anxiety result in decreases in moral disengagement regarding counterfeit purchases. The end result is that low authenticity signals lead to lower purchase intentions and actual spending on counterfeit luxury goods compared to high authenticity signals. In a final study, the authors use these findings to develop a new anticounterfeit advertising strategy, and show it to be effective in reducing females’ interest in purchasing counterfeit luxury products in the future.     

Abstract reasoning and the interpretation of basic conditionals

Studies examining the interpretation that is given to if–then statementstypically use what are referred to as basic conditionals, which give contextless relations between two unrelated concrete terms (If the ball is blue, then the shape is square). However, there is some evidence that basic conditionals require a more abstract form of representation. In order to examine this, we presented participants with truth-table tasks involving either basic conditionals or conditionals referring to imaginary categories (If it is a bori, then it has red wings), and standard conditional inference tasks with abstract and familiar premises. As expected, fewer typical defective conditional interpretations were given to basic conditionals. In addition, partial correlations showed a unique relationship between the interpretation of basic conditionals and abstract inferential reasoning. Results suggest that people process basic conditionals as a form of abstract reasoning, and that the interpretation of conditionals must consider the semantic context.     

Confidence judgments in syllogistic reasoning: the role of consistency and response cardinality

In two experiments, we examined the resolution of confidence judgments in syllogistic reasoning and their heuristic bases. Based on the assumptions of Koriat's Self-Consistency Model of confidence, we expected the confidence judgments to be related to conclusion consensuality, reflecting the role of consistency as a heuristic cue to confidence. In Experiment 1, the participants evaluated 24 syllogisms with conclusions that varied with respect to validity and consensuality. In Experiment 2, the participants produced conclusions to 64 pairs of premises. The correlation between confidence and reasoning accuracy was low. In both experiments confidence was related to the consensuality of the responses. For consensually correct items, correlation between confidence and accuracy was positive; however, for consensually incorrect items it was negative. In Experiment 2, confidence was lower for syllogisms with higher response cardinality, or syllogisms that elicited a greater variety of conclusions.     

Evaluating conditional arguments with uncertain premises

Treating conditionals as probabilistic statements has been referred to as a defining feature of the “new paradigm” in cognitive psychology. Doing so is attractive for several reasons, but it complicates the problem of assessing the merits of conditional arguments. We consider several variables that relate to judging the persuasiveness of conditional arguments with uncertain (probabilistic) premises. We also explore ways of judging the consistency of people's beliefs as represented by components of conditional arguments. Experimental results provide evidence that inconsistencies in beliefs are more prevalent if the arguments’ components are spatially and temporally dispersed than if they are contiguous in space and time. This supports the idea that assuring the consistency among even a small number of beliefs is difficult to do, especially if the beliefs in question are not brought into consciousness at the same time; but consistency can be enhanced when beliefs are considered simultaneously or nearly so.     

Special issue on problem-solving,creativity and spatial reasoning

Problem-solving, creativity and spatial reasoning are high level abilities of cognitive systems with high potential for synergies. However, they have been treated separately by different fields. This special issue presents research work on these topics, aiming to observe their interrelations in order to create theoretical approaches, methodologies and computational tools to advance work on creativity and spatial problem-solving in cognitive systems.
