Temporal discounting is the tendency to devalue temporally distant rewards. Past studies have examined the k-value, the indifference point, and the area under the curve as dependent measures on this task. The current study included these three measures and a fourth measure, called the interest rate total score. The interest rate total score was based on scoring only those items in which the delayed choice should be preferred given the expected return based on simple interest rates. In addition, associations with (...) several individual difference measures were examined including intelligence, executive functions (inhibition, working memory, and set-shifting), thinking dispositions (Need for Cognition and Consideration of Future Consequences) and engagement in substance use and gambling behavior. A staircase temporal discounting task was examined in a sample of 99 university students. Replicating previous studies, temporal discounting increased with longer delays to reward and decreased with higher reward magnitudes. A hyperbolic function accounted for variance in temporal discounting better than an exponential function. Reaction time at the indifference point was significantly longer than at the other choice points. The four dependent measures of temporal discounting were all significantly correlated and were also significantly associated with our individual difference measures. That is, the tendency to wait for a larger delayed reward on all of the temporal discounting measures was associated with higher intelligence, higher executive functions and more consideration of future consequences. Associations between our measures of temporal discounting and outcomes related to substance use and gambling behavior were modest in our university sample. (shrink)

This essay advocates a “functional” approach to causation and causal reasoning: these are to be understood in terms of the goals and purposes of causal thinking. This approach is distinguished from accounts based on metaphysical considerations or on reconstruction of “intuitions.”.

Counterfactual thinking—the capacity to reflect on what would, could, or should have been if events had transpired differently—is a pervasive, yet seemingly paradoxical human tendency. On the one hand, counterfactual thoughts can be comforting and inspiring (Carroll & Shepperd, Chapter 28), but on the other they can be anxiety provoking and depressing (Zeelenberg & Pieters, Chapter 27). Likewise, such thoughts can illuminate pathways toward better future outcomes (Wong, Galinsky, & Kray, Chapter 11), yet they can also promote confusion and (...) lead us astray (Sanna, Schwarz, & Kennedy, Chapter 13). The first part of this chapter focuses on work that supports the prevailing Zeitgeist in the counterfactual thinking literature: Counterfactual thinking is beneficial. The second part of the chapter, however, strikes a more cautionary tone by reviewing work that describes some deleterious consequences of counterfactual thinking. We conclude by offering a tentative reconciliation of these conflicting perspectives and suggesting directions for future research. (shrink)

The notion of functionality is appropriately central to the Newell Test but is also critical at a lower level, in development of cognitive sub-theories. I illustrate, on one hand, how far this principle is from general acceptance among verbal theoreticians, and, on the other hand, how simulation models (here implemented within ACT-R) seem to drive the functional question automatically.

Talk of the functions of language or concepts plays a central role in developing an appealing pragmatic approach to conceptual engineering. But some have expressed skepticism that we can make any good sense of the idea of function as applied to concepts or language, or argued that the most we can say is that the function of ‘F’ is to refer to the Fs. In this paper, however, I argue that identifying linguistic functions is not hopeless, and that we can (...) make progress by working at the level of system functions, and drawing on work in systemic functional linguistics. For that enables us to develop a better framework for thinking about the functions that language serves, and the ways its subsystems contribute to those functions. This approach to understanding linguistic functions enables us to develop a pragmatic approach to conceptual engineering that provides standards for conceptual engineering without metaphysical mysteries. It also enables us to make progress in figuring out what functions certain philosophically interesting parts of language serve, and how they are introduced into language, in ways that may disentangle us from a range of old philosophical problems.

The paper hypothesizes the possibility of applying the mathematical construction of the Taylor series in the semantic space. Then symbolic forms, like some spiritual functions that display the immanent in semantic space and are explicated in the form of verbal constructions, can be tried to decompose into a Taylor series. The first terms of the Taylor series of thinking functions carry basic meanings that are conjectured by secondary forms, tertiary, etc., as in the case of the usual Taylor series, (...) where the first term of the series is a constant, the second term is linear, determined by the first derivative of the function, the third is quadratic, otherwise acceleration. The paper shows that all of the above can be found in the paradigms of thinking called Foucault epistems. The world in ancient philosophy seemed unchangeable or cyclical, which refers us to the concept of a constant or the first term of the Taylor series of the function of thinking. With the advent of Christianity, the circle of time turned into a straight line, the concept of evolution appeared. This stage was completed by Galileo, who introduced the idea of speed into the paradigm of thinking, which completed the formation of the second, linear term of the Taylor series of the thinking function. The third term of the series appeared in Newton's theory and entered the next episteme with the idea of acceleration. Deductively, one can continue the decomposition of the thinking function into a Taylor series and imagine the appearance of a member of the series responsible for the third derivative. (shrink)

This paper discusses idiomatic expressions like ‘that says it all’, ‘that says a lot’ etc. when used in presenting an argument. These expressions are instantiations of the grammatical pattern that says Q, in which Q is an indefinite quantifying expression. By making use of the pragma-dialectical theory of argumentation and the linguistic theory of construction grammar it is argued that instantiations of that says Q expressing positive polarity can fulfil the role of an argumentation’s linking premise. Furthermore, an analysis of (...) these expressions as presentational devices shows that an arguer can use them for strategic reasons, i.e. to leave the exact formulation of the standpoint implicit and to present the argument as self-evident. Using these devices derails into fallaciousness when the context offers insufficient clues to reconstruct the standpoint or when the argument does not offer the kind of support that would be required by the specific instantiation of Q. The argumentative function of instantiations of that says Q expressing negative polarity is that an antagonist can use them to attack the justificatory power of the protagonist’s argument. (shrink)

Pozdně středověký filosof Walter Burley (cca 1275–1344) chápal myšlení jako určitý druh změny, konkrétně jako trpnost, přičemž každý tzv. akt myšlení má podle něho tři hlavní složky: myslící intelekt, pojem a myšlenou věc. Tato studie si dává za cíl prozkoumat, jak Burley pohlížel ve vztahu k myšlení zejména na poslední dvě z těchto složek. První část se pokusí odpovědět na otázku, jakým způsobem dochází ke vzniku pojmů. Druhá část se zaměří na problematiku intencionality našeho myšlení, tj. na otázku, jakým způsobem (...) je podle Burleyho možné říci, že je naše myšlení o nějaké věci. (shrink)

This study investigates moments in which one participant in an interaction embodies that he is “doing thinking,” a display that is commonly referred to as “thinking face. ” From an interactional perspective, it is assumed that embodied displays of “doing thinking” are a recurring social practice and serve interactive functions. While previous studies have examined thinking faces primarily in word searches and storytelling, the present study focuses on argumentative activities, in which children engage in processes of (...) joint decision-making. The paper has two interrelated aims. The first aim is to describe how multiple modalities—beyond the face—are temporally coordinated to create multimodal gestalts of “doing thinking.” It is shown that thinking displays not only involve dynamic imaginative gaze but also stylized bodily postures. The second aim is to generate knowledge about the functions of thinking displays in children's argumentative activities. The analysis describes how both speakers and recipients use thinking displays in different turn positions and align them with verbal talk or silence. The data for this study comprise video recordings of decision-making processes in groups of older children. Drawing on a multimodal approach to situated interaction, it will be proposed that embodied displays of “doing thinking” provide a resource to shape participation frameworks, mark epistemic stances and create epistemic ecologies for collaborative reasoning. By investigating thinking displays in a particular conversational activity, the study sheds light on the diversity and context-sensitive functionality of thinking displays. It also contributes to recent research on children's collaborative reasoning as an embodied discursive practice. (shrink)

Functionalism would be mistaken if there existed a system of deviant relations (an “anti-mind”) that had the same functional roles as the standard mental relations. In this paper such a system is constructed, using “Quinean transformations” of the sort associated with Quine’s thesis of the indeterminacy of translation. For example, a mapping m from particularistic propositions (e.g., that there exists a rabbit) to universalistic propositions (that rabbithood is manifested). Using m, a deviant relation thinking* is defined: x thinks* (...) p iff x thinks m(p). Such deviant relations satisfy the commonly discussed functionalist psychological principles. Finally, a more complicated system of deviant relations is constructed, one satisfying sophisticated principles dealing with the self-conscious rational mind. (shrink)

The present study examined relationships among counterfactual thinking, perceived control, and depressive symptoms. Undergraduate participants, grouped according to nondepressed, mild–to–moderately depressed, and severely depressed symptom categories, described potentially repeatable negative academic events and then made upward counterfactuals about those events. Whereas participants endorsing mild–to–moderate depressive symptom levels generated more counterfactuals about controllable than uncontrollable aspects of the events they described, participants endorsing severe levels of depressive symptoms generated counterfactuals that were less controllable, less reasonable, and more characterological in nature. (...) Furthermore, controllable (relative to uncontrollable) counterfactual thinking enhanced retrospective control perceptions for less depressed participants, but depleted control perceptions for more depressed participants. Discussion focuses on the possibility that whereas controllable counterfactual thinking may be functional for nondepressed individuals, it may be less functional, if not dysfunctional, with increasingly depressed symptoms.

This article is dealt with at a historical-strategic level. Historical processes can be functionally divided into two sections: the social-material-directed Power-organizing part and the cultural-spiritual Ethic-thinking part. Thus there exist two corresponding dynamic-operative functions in history, which are guided and impelled by different motivations, methods, and destinations involved in the two functions. The Ethic-practicing praxis has been always performed through the empirical-humanist-rational ways, which today can be more effectively embodied in human sciences to be reorganized by the general-semiotic strategy. (...) So there are two kinds of human historical courses: the one as the materialist-directed power-organizing part and the other as spiritual-theoretical-directed ethic-reflecting part. From a historical-philosophical point of view, the former is to prepare the material-conditions/means for supporting the latter as the ethic-spiritual mission that is directed towards exploring the meaning/value foundation for human existence. Lacking in the internal link between the two historical-pragmatic functions the ethic-spiritual praxes should manage to find a separate strategy for actively continuing its independent ethic task by dint of wisely/bravely shunning the materialist-determinism issued from the technical/commercialized globalization era.

ABSTRACTWithin-person changes in mood, which are triggered by situational cues, for example someone’s location or company, are thought to affect contemporaneous cognitive function. To test this hypothesis, data were collected over 6 months with the smartphone application moo-Q that prompted users at random times to rate their mood and complete 3 short cognitive tests. Out of 24,313 people across 154 countries, who downloaded the app, 770 participants submitted 10 or more valid moo-Q responses. Confirming previous research, consistent patterns of association (...) emerged for 6 different situation cues with mood and cognitive function: For example, being alone rather than with others when completing the app resulted in worse mood but better cognitive task performance. Notwithstanding, changes in mood and cognitive function were not coupled. The advantages and challenges of using smartphone technology for studying mood and cognitive function are discussed.

Literature relating to gender and discourse has shown that the features and structure of women's talk are highly cooperative. The implicature taken from this research has led to a binary opposition of gender stereotyping that allows for the inference that if women's talk is stylistically cooperative then it follows that cooperativity is a characteristic feature of women's social lives. Further, in opposition to this, men are seen as competitive and, as Cameron has rightly noted, analysis that focuses on the `style (...) rather than the substance of what is said' obscures the complex nature of talk and results in unhelpful `competitive/cooperative oppositions'. This article explores the genre of gossip and suggests two main sub-genres `bitching' and `peer group news-giving'. Analysis of instances of women's `bitching' reveals that while women's conversations may rely on interlocutor cooperativity and a collaborative floor, the conversations are underpinned by a need to discursively claim symbolic capital through competition for socially acceptable images of femininity which reproduce a hegemonic ideology of gender.

The performance of 93 children aged 3 and 4 years on a battery of different counterfactual tasks was assessed. Three measures: short causal chains, location change counterfactual conditionals, and false syllogisms—but not a fourth, long causal chains—were correlated, even after controlling for age and receptive vocabulary. Children's performance on our counterfactual thinking measure was predicted by receptive vocabulary ability and inhibitory control. The role that domain general executive functions may play in 3- to 4-year olds' counterfactual thinking development (...) is discussed. (shrink)

Mathematical chemistry is often thought to be a 20th-century subdiscipline of chemistry, but in this paper we discuss several early chemical ideas and some landmarks of chemistry as instances of the mathematical way of thinking; many of them before 1900. By the mathematical way of thinking, we follow Weyl's description of it in terms of functional thinking, i.e. setting up variables, symbolizing them, and seeking for functions relating them. The cases we discuss are Plato's triangles, Geoffroy's (...) affinity table, Lavoisier's classification of substances and their relationships, Mendeleev's periodic table, Cayley's enumeration of alkanes, Sylvester's association of algebra and chemistry, and Wiener's relationship between molecular structure and boiling points. These examples show that mathematical chemistry has much more than a century of history. (shrink)

Language fails not because thought fails, but because no verbal symbols can do justice to the fullness and richness of thought. In his later works, more specifically in his seminal 1930 essay “Qualitative Thought”, John Dewey questioned some of the traditional assumptions about the nature and function of the qualitative in inquiry. Dewey foresaw what recent scientific accounts of human thinking are confirming: it is more complex, less linear, more emotional, affective, bodily-based, non-reflective, non-linguistic, non-conscious than philosophers have assumed. (...) Secondary sources on Dewey have emphasized how, contrary to orthodoxy, inquiry is social, instrumental, and experimental, but for... (shrink)

Visual thinking -- visual imagination or perception of diagrams and symbol arrays, and mental operations on them -- is omnipresent in mathematics. Is this visual thinking merely a psychological aid, facilitating grasp of what is gathered by other means? Or does it also have epistemological functions, as a means of discovery, understanding, and even proof? By examining the many kinds of visual representation in mathematics and the diverse ways in which they are used, Marcus Giaquinto argues that visual (...) thinking in mathematics is rarely just a superfluous aid; it usually has epistemological value, often as a means of discovery. Drawing from philosophical work on the nature of concepts and from empirical studies of visual perception, mental imagery, and numerical cognition, Giaquinto explores a major source of our grasp of mathematics, using examples from basic geometry, arithmetic, algebra, and real analysis. He shows how we can discern abstract general truths by means of specific images, how synthetic a priori knowledge is possible, and how visual means can help us grasp abstract structures. Visual Thinking in Mathematics reopens the investigation of earlier thinkers from Plato to Kant into the nature and epistemology of an individual's basic mathematical beliefs and abilities, in the new light shed by the maturing cognitive sciences. Clear and concise throughout, it will appeal to scholars and students of philosophy, mathematics, and psychology, as well as anyone with an interest in mathematical thinking. (shrink)

In The Rational Imagination, Byrne proposes a mental models account of why causal and counterfactual thinking often focus on different antecedents. This review critically examines the two central propositions of her account, finding both only weakly defensible. Byrne's account is contrasted with judgment dissociation theory, which offers a functional explanation for differences in the focus of causal and counterfactual thinking.

Functional language is ubiquitous in ecology, mainly in the researches about biodiversity and ecosystem function. However, it has not been adequately investigated by ecologists or philosophers of ecology. In the contemporary philosophy of ecology we can recognize a kind of implicit consensus about this issue: while the etiological approaches cannot offer a good concept of function in ecology, Cummins’ systemic approach can. Here we propose to go beyond this implicit consensus, because we think these approaches are not adequate for (...) ecology. We argue that a sound epistemological framework to function in ecology is to be found in organizational approaches. In this line, we define function in ecology as a precise effect of a given constraint on the ecosystem flow of matter and energy performed by a given item of biodiversity, within a closure of constraints. We elaborate on this definition by developing a case study of a bromeliad ecosystem. (shrink)

Engineers use neural networks to control systems too complex for conventional engineering solutions. To examine the behavior of individual hidden units would defeat the purpose of this approach because it would be largely uninterpretable. Yet neurophysiologists spend their careers doing just that! Hidden units contain bits and scraps of signals that yield only arcane hints about network function and no information about how its individual units process signals. Most literature on single-unit recordings attests to this grim fact. On the other (...) hand, knowing a system's function and describing it with elegant mathematics tell one very little about what to expect of interneuronal behavior. Examples of simple networks based on neurophysiology are taken from the oculomotor literature to suggest how single-unit interpretability might decrease with increasing task complexity. It is argued that trying to explain how any real neural network works on a cell-by-cell, reductionist basis is futile and we may have to be content with trying to understand the brain at higher levels of organization.

_Thinking about Science, Reflecting on Art: Bringing Aesthetics and Philosophy of Science togethe_r is the first book to systematically examine the relationship between the philosophy of science and aesthetics. With contributions from leading figures from both fields this edited collection engages with such questions as: Does representation function in the same way in science and in art? What important characteristic do scientific models share with literary fictions? What is the difference between interpretation in the sciences and in the arts? Can (...) there be a science of aesthetics? In what ways can aesthetics and philosophy of science be integrated? Aiming to develop the interconnections between the philosophy of science and the philosophy of art more broadly and more deeply than ever before this volume not only explores scientific representation by comparison with fiction but extends the scope of interaction to include metaphysical and other questions around methodology in mainstream philosophy of science, including the aims of science, the characterisation of scientific understanding, and the nature of observation, as well as drawing detailed comparisons between specific examples in both art and the sciences.

A satisfactory analysis of human deception must rule out cases where it is a mistake or an accident that person B was misled by person A's behavior. Therefore, most scholars think that deceivers must intend to deceive. This article argues that there is a better solution: rather than appealing to the deceiver's intentions, we should appeal to the function of their behavior. After all, animals and plants engage in deception, and most of them are not capable of forming intentions. Accordingly, (...) certain human behavior is deceptive if and only if its function is to mislead. This solves our problem because if the function of A's behavior was to mislead, B's ending up misled was not an accident or a mere mistake even if A did not intend to deceive B. (shrink)

Evolutionary psychology is put forward by its defenders as an extension of evolutionary biology, bringing psychology within the integrated causal chain of the hard sciences. It is extolled as a new paradigm for integrating psychology with the rest of science. We argue that such claims misrepresent the methods and explanations of evolutionary biology, and present a distorted view of the consequences that might be drawn from evolutionary biology for views of human nature. General theses about adaptation in biology are empty (...) schemata, not laws of nature allowing the subsumption of mind under biology. Functional thinking is an indispensable tool for psychology, mostly of value in abstractive unification and as a heuristic, but it gains little from association with evolutionary notions of selection. Thus, we argue, the cherished integrative causal model evaporates, and evolutionary phraseology serves no more than rhetorical purposes. Moreover, the universality of human nature and the evolutionary irrelevance of individual variation are presented as biological truths that psychologists should respect in their approach to mind. On closer inspection, this turns out to be rather dubious biology. Psychology might conceivably be better off as a continuation of biology by different means, but evolutionary psychology does not provide the conceptual integration leading to such a happy union.

This chapter establishes the concept of a “symbolic system of representation“ to make clear how it is possible that humans use not only the language-based system of representation for cognitive contents but also a many layered non-linguistic system, a system which we probably share with other species. A symbolic system of representation denotes a general concept of a performance of which our language is only one single case, but which nevertheless is most easily explained through the case of language. A (...) system of representation should enable us to form and manipulate an idea of a state of affairs or of an event without having the appropriate intuition of it. We usually think that we do this only using linguistic expressions, but this is not the whole truth. Language is one system of representation, but we can in principle conceive of other systems of representation with the same performance. Husserl’s theory of meaning already reveals this possibility. A phenomenological analysis reveals that a non-linguistic system of representation is in fact still functioning in our own consciousness. We simultaneously use different means of representation, the most prominent of which are language, gestures, feelings and scenic images. It is especially fruitful to investigate the scenic mode of daydreaming as a central form of non-linguistic thinking. Through a close comparison of alternative systems of representation, the systematic difference of usual semantics in normal language systems based on convention and the more natural similarity semantics of some non-linguistic systems of representation is revealed.

Why do people create extra representations to help them make sense of situations, diagrams, illustrations, instructions and problems? The obvious explanation— external representations save internal memory and com- putation—is only part of the story. I discuss seven ways external representations enhance cognitive power: they change the cost structure of the inferential landscape; they provide a structure that can serve as a shareable object of thought; they create persistent referents; they facilitate re- representation; they are often a more natural representation of (...) structure than mental representations; they facilitate the computation of more explicit encoding of information; they enable the construction of arbitrarily complex structure; and they lower the cost of controlling thought—they help coordinate thought. Jointly, these functions allow people to think more powerfully with external representations than without. They allow us to think the previously unthinkable. (shrink)

In the region where some cat sits, there are many very cat-like items that are proper parts of the cat (or otherwise mereologically overlap the cat) , but which we are inclined to think are not themselves cats, e.g. all of Tibbles minus the tail. The question is, how can something be so cat-like without itself being a cat. Some have tried to answer this “Problem of the Many” (a problem that arises for many different kinds of things we regularly (...) encounter, including desks, persons, rocks, and clouds) by relying on a mereological maximality principle, according to which, something cannot be a member of a kind K if it is a large proper part of, or otherwise greatly mereologically overlaps, a K. It has been shown, however, that a maximality constraint of this type, i.e. one that restricts mereological overlap, is open to strong objections. Inspired by the insights of, especially, Sutton and Madden, I develop a type of functional-maximality principle that avoids these objections (and has other merits), and thereby provides a better answer to the Problem of the Many.

“Critical thinking in higher education” is a phrase that means many things to many people. It is a broad church. Does it mean a propensity for finding fault? Does it refer to an analytical method? Does it mean an ethical attitude or a disposition? Does it mean all of the above? Educating to develop critical intellectuals and the Marxist concept of critical consciousness are very different from the logician’s toolkit of finding fallacies in passages of text, or the practice (...) of identifying and distinguishing valid from invalid syllogisms. Critical thinking in higher education can also encompass debates about critical pedagogy, i.e., political critiques of the role and function of education in society, critical feminist approaches to curriculum, issues related to what has become known as critical citizenship, or any other education-related topic that uses the appellation “critical”. Equally, it can, and usually does, refer to the importance and centrality of developing general skills in reasoning—skills that we hope all graduates possess. Yet, despite more than four decades of dedicated scholarly work “critical thinking” remains as elusive as ever. As a concept, it is, as Raymond Williams has noted, a ‘most difficult one’ (Williams, 1976, p. 74). (shrink)

In the late 20th century theorists within the radical feminist tradition such as Haraway highlighted the impossibility of separating knowledge from knowers, grounding firmly the idea that embodied bias can and does make its way into argument. Along a similar vein, Moulton exposed a gendered theme within critical thinking that casts the feminine as toxic ‘unreason’ and the ideal knower as distinctly masculine; framing critical thinking as a method of masculine knowers fighting off feminine ‘unreason’. Theorists such as (...) Burrow have picked up upon this tradition, exploring the ways in which this theme of overly masculine, or ‘adversarial’, argumentation is both unnecessary and serves as an ineffective base for obtaining truth. Rooney further highlighted how this unnecessarily gendered context results in argumentative double binds for women, undermining their authority and stifling much-needed diversity within philosophy as a discipline.These are damning charges that warrant a response within critical thinking frameworks. We suggest that the broader critical thinking literature, primarily that found within contexts of critical pedagogy and dispositional schools, can and should be harnessed within the critical thinking literature to bridge the gap between classical and feminist thinkers. We highlight several methods by which philosophy can retain the functionality of critical thinking while mitigating the obstacles presented by feminist critics and highlight how the adoption of such methods not only improves critical thinking, but is also beneficial to philosophy, philosophers and feminists alike.

This chapter argues that our language faculty can both be a peripheral module of the mind and be crucially implicated in a variety of central cognitive functions, including conscious propositional thinking and reasoning. I also sketch arguments for the view that natural language representations (e.g. of Chomsky's Logical Form, or LF) might serve as a lingua franca for interactions (both conscious and non-conscious) between a number of quasi-modular central systems. The ideas presented are compared and contrasted with the evolutionary (...) proposals made by Derek Bickerton (1990, 1995), who has also argued for the involvement of language in thought. Finally, I propose that it was the evolution of a mechanism responsible for pretend play, circa 40,000 years ago, which led to the explosion of creative culture visible in the fossil record from that time onwards.
