Elementary Polyhedral Mereotopology

A region-based model of physical space is one in which the primitive spatial entities are regions, rather than points, and in which the primitive spatial relations take regions, rather than points, as their relata. Historically, the most intensively investigated region-based models are those whose primitive relations are topological in character; and the study of the topology of physical space from a region-based perspective has come to be called mereotopology. This paper concentrates on a mereotopological formalism originally introduced by Whitehead, which employs a single primitive binary relation C(x,y) (read: x is in contact with y). Thus, in this formalism, all topological facts supervene on facts about contact. Because of its potential application to theories of qualitative spatial reasoning, Whitehead's primitive has recently been the subject of scrutiny from within the Artificial Intelligence community. Various results regarding the mereotopology of the Euclidean plane have been obtained, settling such issues as expressive power, axiomatization and the existence of alternative models. The contribution of the present paper is to extend some of these results to the mereotopology of three-dimensional Euclidean space. Specifically, we show that, in a first-order setting where variables range over tame subsets of R ³, Whitehead's primitive is maximally expressive for topological relations; and we deduce a corollary constraining the possible region-based models of the space we inhabit.     

High cost helping scenario: The role of empathy,prosocial reasoning and moral disengagement on helping behavior

This study aimed to investigate the process that leads people to offer or omit help in response to an explicit request for assistance, taking into account both emotional and cognitive factors. Specifically, a hypothetical scenario methodology was used in a sample of 174 Italian youths (50% males) to examine whether and how factors such as empathy, prosocial moral reasoning and moral disengagement influence the propensity to help when providing assistance is not in the individual’s personal interest. While a few previous studies have included moral disengagement as an antecedent of prosocial decision making, we highlight the significance of this factor in the avoidance of moral responsibility towards others in need. The results highlight two ways in which differences in emotional tendencies and moral-cognitive processes may operate in prosocial decision making in high personal cost situations. First, high empathy levels could promote an altruistic response which in turn fosters mature prosocial moral reasoning. Second, personal distress may enhance moral disengagement mechanisms that may facilitate self-centred behaviors.     

Undecidable Decisions: Rationality Limits and Decision-making Heuristics

In this article the theoretic evolution and the empirical-experimental efforts that have led to the affirmation of the bounded/procedural rationality paradigm are discussed. Moreover, the debate on supporters of the “optimization” approach and supporters of the “bounded/procedural rationality” approach is traced, highlighting the irreconcilability of these two approaches and, in retort, a solid defense against a merely “reductionist” attempt of the innovative context of the Simonian theory. Critically going over the debate on decision dynamics, it becomes clear how, due to the uncertain nature of rational processes, it is impossible to establish the decision-making best way. The imperfect character of individual choice is explained by how the decider identifies a solution that appears satisfying in that moment due to cognitive and temporal limits.     

道德和习俗领域幼儿义务推理的发展

采用Keller, Gummerum, Wang和Lindsey (2004)的不知情义务推理范式, 探讨了96名4、5、6岁幼儿对通过条件规则表述的鼓励性或禁止性的道德规则、以及习俗规则的义务推理能力的发展。结果表明：1)幼儿对两种不同领域规则的义务推理表现出基本一致的发展规律, 表现出显著的“角色效应”, 即多数幼儿都能指出同伴违反, 随年龄增大指出妈妈违反、双违反的人次百分比逐渐增多, 尤其是一些4岁幼儿就能正确指出道德和习俗领域中的妈妈违反, 部分5岁幼儿即可正确指出双违反。2)在不知情的义务推理范式下, 一些4岁幼儿错误指出本来是妈妈违反约定的情境中同伴违反、一些6岁幼儿错误指出本来是同伴违反约定的鼓励性规则情境中妈妈违反。3)尽管幼儿对道德和习俗规则的义务推理没有差异, 他们对不同性质社会规则的义务推理却表现出显著差异。5、6岁幼儿对禁止性的道德规则中同伴违反的检测显著低于对鼓励性的道德规则, 而6岁幼儿对双违反中妈妈违反的检测则相对更高; 6岁幼儿对习俗规则的义务推理也表现出类似的不同性质之间的差异。这些结果在一定程度上突破了以往的研究结论, 反映出幼儿对道德和习俗规则进行义务推理时表现出的跨领域的一般性及其领域内的特殊性。     

Pretense,Counterfactuals, and Bayesian Causal Models: Why What Is Not Real Really Matters

Young children spend a large portion of their time pretending about non‐real situations. Why? We answer this question by using the framework of Bayesian causal models to argue that pretending and counterfactual reasoning engage the same component cognitive abilities: disengaging with current reality, making inferences about an alternative representation of reality, and keeping this representation separate from reality. In turn, according to causal models accounts, counterfactual reasoning is a crucial tool that children need to plan for the future and learn about the world. Both planning with causal models and learning about them require the ability to create false premises and generate conclusions from these premises. We argue that pretending allows children to practice these important cognitive skills. We also consider the prevalence of unrealistic scenarios in children's play and explain how they can be useful in learning, despite appearances to the contrary.     

The Influence of Activation Level on Belief Bias in Relational Reasoning

A novel explanation of belief bias in relational reasoning is presented based on the role of working memory and retrieval in deductive reasoning, and the influence of prior knowledge on this process. It is proposed that belief bias is caused by the believability of a conclusion in working memory which influences its activation level, determining its likelihood of retrieval and therefore its effect on the reasoning process. This theory explores two main influences of belief on the activation levels of these conclusions. First, believable conclusions have higher activation levels and so are more likely to be recalled during the evaluation of reasoning problems than unbelievable conclusions, and therefore, they have a greater influence on the reasoning process. Secondly, prior beliefs about the conclusion have a base level of activation and may be retrieved when logically irrelevant, influencing the evaluation of the problem. The theory of activation and memory is derived from the Atomic Components of Thought‐Rational (ACT‐R) cognitive architecture and so this account is formalized in an ACT‐R cognitive model. Two experiments were conducted to test predictions of this model. Experiment 1 tested strength of belief and Experiment 2 tested the impact of a concurrent working memory load. Both of these manipulations increased the main effect of belief overall and in particular raised belief‐based responding in indeterminately invalid problems. These effects support the idea that the activation level of conclusions formed during reasoning influences belief bias. This theory adds to current explanations of belief bias by providing a detailed specification of the role of working memory and how it is influenced by prior knowledge.     

Essentialist Beliefs About Bodily Transplants in the United States and India

Psychological essentialism is the belief that some internal, unseen essence or force determines the common outward appearances and behaviors of category members. We investigated whether reasoning about transplants of bodily elements showed evidence of essentialist thinking. Both Americans and Indians endorsed the possibility of transplants conferring donors' personality, behavior, and luck on recipients, consistent with essentialism. Respondents also endorsed essentialist effects even when denying that transplants would change a recipient's category membership (e.g., predicting that a recipient of a pig's heart would act more pig‐like but denying that the recipient would become a pig). This finding runs counter to predictions from the strongest version of the “minimalist” position (Strevens,2000), an alternative to essentialism. Finally, studies asking about a broader range of donor‐to‐recipient transfers indicated that Indians essentialized more types of transfers than Americans, but neither sample essentialized monetary transfer. This suggests that results from bodily transplant conditions reflect genuine essentialism rather than broader magical thinking.     

Influence of motivated reasoning on saving and spending decisions

The decision to save enhances well-being in the long-term but it conflicts with the desire to spend money to gain immediate gratification. In this research, we examine the influence of having single versus multiple accounts on individuals’ savings and spending decisions. We find that individuals save more with a single account than with multiple liquid accounts. Utilizing work on motivated reasoning and fuzzy-trace theory, we suggest that multiple accounts engender fuzzy gist representations, making it easier for people to generate justifications to support their desired spending decisions. However, a single account reduces the latitude for distortion and hinders generation of justifications to support desirable spending decisions. Across four studies that provide participants with the opportunity to earn, spend, and save money, we demonstrate the proposed effect and test the underlying process.     

Animals,humans and x-men: Human uniqueness and the meaning of personhood

Research in animal intelligence suggests to some that humans are different only in degree from animals, possibly eroding the traditional theological doctrine of the imago dei. In this paper, several critical boundary areas between humans and animals are examined for scientific evidence about human distinctiveness. These include communication and language capacity, cultural creativity, spirituality, and ethical capacity. Chimpanzee language studies and research in Neanderthal mentality are examined as the closest known natural approximations to human communication and intelligence. The implications of the findings are explored in relation to human culture, ethics, and spirituality in a context consistent with evolutionary continuity. Aspects of human uniqueness are apparent, can be fruitfully encompassed in the idea of personhood, and are coherent with Trinitarian theology's anthropological focus.     

The development of children’s sympathy,moral emotion attributions,and moral reasoning in two cultures

The current study investigated the development of children’s sympathy, moral emotion attributions, and moral reasoning in two cultures: Chile and Switzerland. One hundred seventy-six children in two age groups (i.e., 6 and 9 years old) were asked to report their sympathy. Moral emotion attributions and moral reasoning were measured using two hypothetical moral transgressions (i.e., omitting a prosocial duty, stealing from another child). Younger Chilean children reported higher levels of sympathy than younger Swiss children. Across cultures, older children attributed more moral emotions than did younger children. Younger Swiss children used more moral reasoning following judgements about rule violations than did younger Chilean children. The findings are discussed from both a developmental and cross-cultural perspective.
