Who uses more strategies? Linking mathematics anxiety to adults’ strategy variability and performance on fraction magnitude tasks.Pooja G. Sidney,Rajaa Thalluri,Morgan L. Buerke &Clarissa A.Thompson -2018 -Thinking and Reasoning 25 (1):94-131.detailsABSTRACTAdults use a variety of strategies to reason about fraction magnitudes, and this variability is adaptive. In two studies, we examined the relationships between mathematics anxiety, working memory, strategy variability and performance on two fraction tasks: fraction magnitude comparison and estimation. Adults with higher mathematics anxiety had lower accuracy on the comparison task and greater percentage absolute error on the estimation task. Unexpectedly, mathematics anxiety was not related to variable strategy use. However, variable strategy use was linked to more accurate (...) magnitude comparisons, especially among adults with lower working memory performance or those who use mathematics less frequently, as well as lower PAE on the estimation task. These findings shed light on the role of strategy variability in fraction problem solving and demonstrate a link between mathematics anxiety and fraction magnitude reasoning, a key predictor of general mathematics achievement.

The Other Side of Cognitive Control: Can a Lack of Cognitive Control Benefit Language and Cognition?Evangelia G. Chrysikou,Jared M. Novick,John C. Trueswell &Sharon L.Thompson-Schill -2011 -Topics in Cognitive Science 3 (2):253-256.detailsCognitive control refers to the regulation of mental activity to support flexible cognition across different domains. Cragg and Nation (2010) propose that the development of cognitive control in children parallels the development of language abilities, particularly inner speech. We suggest that children’s late development of cognitive control also mirrors their limited ability to revise misinterpretations of sentence meaning. Moreover, we argue that for certain tasks, a tradeoff between bottom-up (data-driven) and top-down (rule-based) thinking may actually benefit performance in both children (...) and adults. Specifically, we propose that a lack of cognitive control may promote important aspects of cognitive development, like language acquisition and creativity. (shrink)
Intentionality and causality in John Searle.David L.Thompson -1986 -Canadian Journal of Philosophy 16 (1):83-97.detailsIntentionality, as Brentano originally introduced the term in modern philosophy, was meant to provide a distinctive characteristic definitively separating the mental from the physical.(1) Mental states have an intrinsic relationship to an object, to that which they are "about." Physical entities just are what they are, they cannot, by their very essence, refer to anything, they have no "outreach", as one might put it. Mental states have, as it were, an incomplete essence, they cannot exist at all unless they are (...) completed by something other than themselves, their object. Brentano's position is opposed to all theories which represent the mental as only extrinsically related to the world, that is, to all theories in which mental states are themselves self-sufficient for their own existence and only secondarily relate to the world by means of something external to their nature, e.g., neurological causation, divine intervention, or pre-established harmony. In these later cases, any mental act whatsoever could be related to any object, or indeed to none, for the relation is external to the nature of the act, it is superimposed on it by outside forces. Brentano's point is that a mental act has, by its very essence, an Intentional object without which it would not be a mental act. It would therefore appear that since causality is an external relationship which could in principle relate any two things regardless of their nature, the Intentional relation between an act and its object cannot be a causal relation.

Lee,Jean-Claude Tardif,Erika Kleiderman & Marcotte -2021 -BMC Medical Ethics 22 (1):1-15.detailsBackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

Equity and resilience in local urban food systems: a case study.Tiffanie F. Stone,Erin L. Huckins,Eliana C. Hornbuckle,Janette R.Thompson &Katherine Dentzman -2024 -Agriculture and Human Values 41 (3):1239-1256.detailsLocal food systems can have economic and social benefits by providing income for producers and improving community connections. Ongoing global climate change and the acute COVID-19 pandemic crisis have shown the importance of building equity and resilience in local food systems. We interviewed ten stakeholders from organizations and institutions in a U.S. midwestern city exploring views on past, current, and future conditions to address the following two objectives: 1) Assess how local food system equity and resilience were impacted by the (...) COVID-19 pandemic, and 2) Examine how policy and behavior changes could support greater equity and resilience within urban local food systems. We used the Community Capitals Framework to organize interviewees’ responses for qualitative analyses of equity and resilience. Four types of community capital were emphasized by stakeholders: cultural and social, natural, and political capital. Participants stated that the local food system in this city is small; more weaknesses in food access, land access, and governance were described than were strengths in both pre- and post-pandemic conditions. Stakeholder responses also reflected lack of equity and resilience in the local food system, which was most pronounced for cultural and social, natural and political capitals. However, local producers’ resilience during the pandemic, which we categorized as human capital, was a notable strength. An improved future food system could incorporate changes in infrastructure (e.g., food processing), markets (e.g., values-based markets) and cultural values (e.g., valuing local food through connections between local producers and consumers). These insights could inform policy and enhance community initiatives and behavior changes to build more equitable and resilient local food systems in urban areas throughout the U.S. Midwest. (shrink)
Issues in Evolutionary Ethics.PaulThompson (ed.) -1995 - State University of New York Press.detailsThis book explores historical and current discussions of the relevance of evolutionary theory to ethics. The historical section conveys the intellectual struggle that took place within the framework of Darwinism from its inception up to the work of G. C. Williams, W. D. Hamilton, R. D. Alexander, A. L. Trivers, E. O. Wilson, R. Dawkins, and others. The contemporary section discusses ethics within the framework of evolutionary theory as enriched by the works of biologists such as those mentioned above. The (...) issue of whether ethical practice and ethical theory can be grounded in the theory of evolution has taken a new and significant direction within the context of sociobiology and is proving to be a challenge to previous thinking. This book conveys that challenge. (shrink)

Complexly fractionated syllogistic quantifiers.Philip L. Peterson -1991 -Journal of Philosophical Logic 20 (3):287 - 313.detailsConsider syllogisms in which fraction (percentage) quantifiers are permitted in addition to universal and particular quantificrs, and then include further quantifiers which are modifications of such fractions (such as "almost ½ the S are P" and "Much more than ½ the S are P"). Could a syllogistic system containing such additional categorical forms be coherent?Thompson's attempt (1986) to give rules for determining validity of such syllogisms has failed; cf. Carnes & Peterson (forthcoming) for proofs of the unsoundness and (...) incompleteness ofThompson's rules. Building on Peterson (1985), the coherence of such a syllogistic can, however, be demonstrated with an algebra which provides its semantics; e.g., "almost ¾ the S arc P'" is represented as " -(3(SP) » SP)".

TΓxanΩ for TΓxanΩ Ωn in Attic Prose.W. L. Lorimer -1926 -Classical Quarterly 20 (3-4):195-.detailsThe question whether τυγχνω can be used forτυγχνω ν in Attic Prose has been differently answered by different scholars. Phrynichus held that it could not, and Porson followed him. The generality of modern scholars, however, have taken the other view—so, e.g., Locella, Heindorf, Lobeck, Ast, Schneider, Madvig, Stallbaum, Krüger, W. H.Thompson, Rutherford, Jebb, Adam, Kühner-Gerth. The object of the present note is to show that the ‘modern’ view, if it is to be maintained, must be based on other (...) evidence than that hitherto given for it. (shrink)

Linguistic picture of the world and the problem of lexis classifying in modern dictionary form.L. G. Sayakhova -2013 -Liberal Arts in Russia 2 (4):368.detailsTheoretical basis of the article is the interpretation of the lexis as a system, conditioned by the natural unity of the linguistic and extra-linguistic factors. But the main factor that influences the lexical system still is the relations of the reality itself, ordered in this language system. The article discusses the need to create a body of new thesaurus dictionaries of integrated type. The novelty of the problem is based on the achievements of modern linguistics in the study of lexis, (...) as well as the dynamics and variability of modern life when the whole layers of lexical units becoming ''obsolete'' (for example, in sections ''Man'', ''Society'') and quite a significant part of the lexical units on the contrary is updating. The paper defines the principles and forms of creating new generation of the dictionaries of the Russian language. The article concept may be of interest to foreign professionals engaged in lexicography. (shrink)
