Connecting Spatial Reasoning Process to Geometric Problem

The field of spatial reasoning has seen a lot of research. The process of spatial reasoning, on the other hand, needs to be investigated further. The goal of this study is to capture an elementary school student's spatial reasoning process when solving geometric problems. The spatial skills used in solving geometric problems were also identified in this study. A geometric test was given to seventeen elementary school students. Three participants were chosen as the study's subjects based on their written responses. According to the findings, the subject's spatial reasoning process always begins with the processing of information in mental visualization. Mental visualization is used to help with orientation and selecting the appropriate visual perspective. The spatial skills of spatial visualization and spatial orientation are critical in spatial reasoning. Furthermore, this research initiated the emphasis on the focus of spatial reasoning in the process.

Does the Intuition of Distinctness Result from Valid Reasoning? – Reply to Kammerer

According to an influential physicalist view, the intuition of distinctness is a cognitive illusion in the sense that it results from fallacious reasoning: we erroneously infer that the referents of phenomenal and physical concepts are different, from the fact that there is a certain difference between our uses of those concepts. (Kammerer, Review of Philosophy and Psychology 10:649–667, 2019) has recently argued, however, that it is psychologically implausible that the intuition of distinctness results from a fallacy: the reasoning process leading to this intuition is, in several psychological respects, similar to valid reasoning and dissimilar to typical fallacies, which gives us a reason to think that this process is a case of valid reasoning. I argue that there are no psychological reasons to think that the process underlying the intuition of distinctness (or at least the crucial part of this process) is a case of valid reasoning. There is, in fact, only one crucial psychological respect in which this process resembles valid reasoning, and although the two processes are similar in one crucial respect, this does not rule out that the intuition of distinctness results from a fallacy, namely, the sort of fallacious reasoning that physicalists have in mind. Furthermore, since the process underlying the intuition of distinctness resembles typical fallacies in one crucial respect, there is a reason to think that the intuition of distinctness does result from a fallacy.

Primary care physiotherapists ability to make correct management decisions – is there room for improvement? A mixed method study

Background With increasing interest in direct access to physiotherapy, it is important to consider the physiotherapists (PTs) ability to make correct management decisions, because identification of differential diagnostic pathologies and timely referral for specialist care is vital for patient safety. The aims of the study were to investigate PTs ability to make correct management decisions in patients presenting with musculoskeletal conditions and to identify explanatory factors associated with this ability. Furthermore, we wanted to explore the PTs views on the identified factors. Methods The study was a mixed methods study with an explanatory sequential design consisting of a questionnaire survey and semi-structured interviews. The questionnaire comprised 12 clinical vignettes describing patient scenarios for musculoskeletal conditions, non-critical medical conditions and critical medical conditions. Based on this, the PTs indicated whether the patient should be managed by the PT or were in need of medical referral. Associations between correct decisions and explanatory variables was analyzed by mixed- effects logistic regression. Interviews were performed with nine PTs to explore their reactions to the results. A directed content analysis was performed. Results A total of 195 PTs participated in the questionnaire survey and 9 PTs were interviewed. Overall, PTs were more likely to make correct management decisions in the musculoskeletal conditions category, whereas wrong decisions were more often chosen for underlying medical conditions categories. Positive associations between correct management decision in the critical medical category were found for experience: odds ratio (OR) 2.73 (1.33;5.57) and passed quality audit OR 2.90 (1.50;5.58). In the interviews, PTs expressed concerns about the differential diagnostic abilities. They all noted, that experience is immensely important in the clinical reasoning process because the ability to recognise diagnostic patterns evolves over time. Furthermore, the quality audit seems to address and systematize the clinical reasoning process and workflow within the clinics. Conclusion The lack of ability to make correct management decision in critical medical categories and the uncertainties expressed by PT’s should raise concern, as direct access to physiotherapy is already well-established and the results indicate that patient safety could be at risk. The findings that experience and passed quality audit was associated with correct management decisions highlights the need for ongoing awareness and education into differential diagnostics.

Object or Background: An Interpretable Deep Learning Model for Covid-19 Detection from CT-Scan Images

The new strains of the pandemic Covid-19 are still looming. It is important to develop multiple approaches for timely and accurate detection of Covid-19 and its variants. Deep learning techniques are well proved for their efficiency in providing solutions to many social and economic problems. However, the transparency of the reasoning process of a deep learning model related to a high stake decision is a necessity. In this work, we propose an interpretable deep learning model Ps-ProtoPNet to detect Covid-19 from the medical images. Ps-ProtoPNet classifies the images by recognizing the objects rather than their background in the images. We demonstrate our model on the dataset of the chest CT-scan images. The highest accuracy that our model achieves is 99.29%

BRAHMAGUPTA AND THE CONCEPT OF ZERO

This paper attempts to reconstruct the possible reasoning process that led the Indian mathematician Brahmagupta in 628 A.D. to the formulation of two controversial rules for arithmetic involving the number zero; rules which, contradict the modern arithmetic. This paper outlines a possible explanation of the issue based on similar reasoning.

Reasoning on with Defeasibility in ASP

Reasoning on defeasible knowledge is a topic of interest in the area of description logics, as it is related to the need of representing exceptional instances in knowledge bases. In this direction, in our previous works we presented a framework for representing (contextualized) OWL RL knowledge bases with a notion of justified exceptions on defeasible axioms: reasoning in such framework is realized by a translation into ASP programs. The resulting reasoning process for OWL RL, however, introduces a complex encoding in order to capture reasoning on the negative information needed for reasoning on exceptions. In this paper, we apply the justified exception approach to knowledge bases in , that is, the language underlying OWL QL. We provide a definition for knowledge bases with defeasible axioms and study their semantic and computational properties. In particular, we study the effects of exceptions over unnamed individuals. The limited form of axioms allows us to formulate a simpler ASP encoding, where reasoning on negative information is managed by direct rules. The resulting materialization method gives rise to a complete reasoning procedure for instance checking in with defeasible axioms.1

FORMULATING GUIDELINES FOR THE SYSTEMATIC SET-UP OF EXPERIENTIAL MATERIAL CHARACTERIZATION STUDIES: A CASE OF PLASTIC DEMONSTRATORS

Materials can be considered from a technical and experiential perspective. However, the latter perspective is more complex to study systematically. Four intertwined experiential levels describe the overall materials experience: sensorial, interpretive, affective, and performative level. Building upon the need in experiential material characterization for comparable physical material representations to enable within-material-class comparisons and the inclusion of extensive user aspects, this paper sums up the reasoning process regarding the understanding and design of an experimental set-up and its parameters of a specific case. The case objective is to formulate guidelines for the designer/researcher to set up experiential material characterization experiments with (i) plastic demonstrator forms and (ii) by consumers. Following elements are discussed: Assessors, Stimuli, Interaction Modalities, Dependent variables, Method, and Practical considerations. Next, future experiments can be carried out in order to generate holistic plastic material data on a larger scale, that can be collected in an experiential database and used by designers throughout the design process.

Wise reasoning, intergroup positivity, and attitude polarization across contexts

We hypothesized that a wisdom-based reasoning process comprised of epistemic humility, accounting for context, and integrating different perspectives and interests, would be helpful in overcoming intergroup bias and attitude polarization in societal conflicts. Here we test the hypothesis using both the Situated Wise Reasoning Scale and experimental induction. In each study, we recruited participants who self-identified as members of a group implicated in an ongoing intergroup situation. In five correlational studies (Studies 1-5) we examined the relations between measured wise reasoning and intergroup positivity and attitude polarization. In two experiments, we tested the effects of a brief online wise-reasoning thought exercise on intergroup positivity and polarization (Studies 6-7), and charitable behaviors to an outgroup (Study 6). We found that wise reasoning relates to more positivity toward outgroups and less attitude polarization across different groups and conflicts. The results have implications for theory and may also have implications for future research on interventions to improve intergroup relations.
