This work represents an attempt to stake out the landscape for dynamicism based on a radical dismissal of the information-processing paradigm that dominates the philosophy of cognitive science. In Section 2, after setting up the basic toolkit of a theory of minimal representationalism, I introduce the central tenets of dynamic systems theory (DST) by discussing recent research in the dynamics of embodiment (Thelen et al. [2001]) in the perseverative-reaching literature. A recent proposal on the dynamics of representation--the dynamic field approach (...) (Spencer and Schöner [2003])-- according to which the alleged representational gap between DST and representational theories of cognition needs to be bridged in order to explain higher-order cognitive activity will then be reviewed. In Section 3 I shall argue that Spencer and Schöner's attempt to bridge the representational gap may jeopardize the whole (antirepresentationalist) spirit of the DST project. In order to show why, I shall introduce the key concepts of "reliability of environment" and "primagenesis", and argue that DST can account for de-coupled, offline cognitive activity with no need of positing representational resources. Conclusions and directions for future research will follow. (shrink)

Online data collection methods are expanding the ease and access of developmental research for researchers and participants alike. While its popularity among developmental scientists has soared during the COVID-19 pandemic, its potential goes beyond just a means for safe, socially distanced data collection. In particular, advances in video conferencing software has enabled researchers to engage in face-to-face interactions with participants from nearly any location at any time. Due to the novelty of these methods, however, many researchers still remain uncertain about (...) the differences in available approaches as well as the validity of online methods more broadly. In this article, we aim to address both issues with a focus on moderated data collected using video-conferencing software. First, we review existing approaches for designing and executing moderated online studies with young children. We also present concrete examples of studies that implemented choice and verbal measures and looking time across both in-person and online moderated data collection methods. Direct comparison of the two methods within each study as well as a meta-analysis of all studies suggest that the results from the two methods are comparable, providing empirical support for the validity of moderated online data collection. Finally, we discuss current limitations of online data collection and possible solutions, as well as its potential to increase the accessibility, diversity, and replicability of developmental science.

In his book Yuck!: The Nature and Moral Significance of Disgust, Daniel Kelly synthesizes a growing body of research on disgust and briefly explores the philosophical role of the emotion. This paper presents arguments for the position that disgust should not be considered a source of moral knowledge, a position that Kelly suggests but fails to illustrate. The paper also explores implications of this view, specifically concerning the ways we should seek to manipulate our disgust reactions in order to improve (...) moral reasoning. (shrink)

Jerry Fodor and Ernest Lepore [(1992) Holism: a shopper's guide, Oxford: Blackwell; (1996) in R. McCauley (Ed.) The Churchlands and their critics , Cambridge: Blackwell] have launched a powerful attack against Paul Churchland's connectionist theory of semantics--also known as state space semantics. In one part of their attack, Fodor and Lepore argue that the architectural and functional idiosyncrasies of connectionist networks preclude us from articulating a notion of conceptual similarity applicable to state space semantics. Aarre Laakso and Gary Cottrell [(1998) (...) in M. A. Gernsbacher & S. Derry (Eds) Proceedings of the 20th Annual Conference of the Cognitive Science Society, Mahway, NJ: Erlbaum; Philosophical Psychology ] 13, 47-76 have recently run a number of simulations on simple feedforward networks and applied a mathematical technique for measuring conceptual similarity in the representational spaces of those networks. Laakso and Cottrell contend that their results decisively refute Fodor and Lepore's criticisms. Paul Churchland [(1998) Journal of Philosophy, 95, 5-32 ] goes further. He uses Laakso and Cottrell's neurosimulations to argue that connectionism does furnish us with all we need to construct a robust theory of semantics and a robust theory of translation. In this paper I shall argue that whereas Laakso and Cottrell's neurocomputational results may provide us with a rebuttal of Fodor and Lepore's argument, Churchland's conclusion is far too optimistic. In particular, I shall try to show that connectionist modelling does not provide any objective criterion for achieving a one-to-one accurate translational mapping across networks. (shrink)

In this paper I shall reply to two arguments that Stephen Stich (1990; 1991; 1996) has recently put forward against the thesis of eliminative materialism. In a nutshell, Stich argues that (i) the thesis of eliminative materialism, according to which propositional attitudes don't exist, is neither true nor false, and that (ii) even if it were true, that would be philosophically uninteresting. To support (i) and (ii) Stich relies on two premises: (a) that the job of a theory of reference (...) is to make explicit the tacit theory of reference which underlies our intuitions about the notion of reference itself; and (b) that our intuitive notion of reference is a highly idiosyncratic one. In this paper I shall address Stich's anti-eliminativist claims (i) and (ii). I shall argue that even if we agreed with premises (a) and (b), that would lend no support whatsoever to (i) and (ii).

Presentation of issue No 66 about epistemic injustices.

Abstract:This paper presents a model of the continuous structure of Cognition based on several theses proposed by Charles S. Peirce in his youth and in his mature period. In this model, cognitions are discontinuous parts on a continuum and a cognitive process becomes “individually-synthetic,” as a hypostatic abstraction from discontinuous transformations of informational fluxes in the continuous course of experience. That is, they are salient regions or neighborhoods on a continuum rather than points, and the relations of succession and precession (...) among them are inferential, fluid, time sensitive, and goal-directed. First, this paper will outline the theses found in the young Peirce’s work, which inspire a conception of continuous Cognition. Two questions will be raised regarding such a conception: (1) at what point does a particular act of cognition conclude? and (2) how should we characterize individual cognitions? To address these questions, the paper will later introduce the concept of continuity that Peirce developed in his mature years. The synthetic character of the continuum leads to the formulation of the concepts of neighborhood and synthetic individuality. These notions support the conception of a continuous model of Cognition in which the relations of succession and precession between individual finite cognitions are explained. The paper ends with a brief reflection regarding the possibility of developing this model of continuous Cognition as a theory of extended cognition. (shrink)

According to Carruthers ants and bees have minds. This claim is to be understood realistically. We do not interpret the overt behaviour of ants and bees by ascribing to them beliefs and desires in an instrumental manner. They rather possess minds in the relevant cognitive sense. In this paper, I propose to pave the way for a reductio against such a polemic view. In particular, I shall argue that if ants and bees have minds, by the same token, plants do (...) have minds too. In my view, the problem has to do with Carruthers' underlying technical concept of cognitive architecture; a concept which, as I shall argue, can be called into question both on empirical and conceptual grounds. Según Carruthers, las hormigas y las abejas tienen mente. Esta afirmación debe entenderse de modo realista. No es que interpretemos la conducta abierta de hormigas y abejas en términos de creencias y deseos atribuidos instrumentalmente. Se trata más bien de que tienen tales estados mentales en el sentido cognitivo relevante. En este trabajo, me propongo llevar esta polémica concepción a una reductio. En particular, argumentaré que si las hormigas y las abejas tienen mente, por la misma razón las plantas también la tendrían. A mi modo de ver, el problema tiene que ver con el concepto técnico de arquitectura cognitiva de Carruthers ; un concepto que puede ser cuestionado sobre bases empíricas y conceptuales, según argüiré.

According to Ramsey (Representation reconsidered, Cambridge University Press, New York, 2007 ), only classical cognitive science, with the related notions of input–output and structural representations, meets the job description challenge (the challenge to show that a certain structure or process serves a representational role at the subpersonal level). By contrast, connectionism and other nonclassical models, insofar as they exploit receptor and tacit notions of representation, are not genuinely representational. As a result, Ramsey submits, cognitive science is taking a U-turn from (...) representationalism back to behaviourism, thus presupposing that (1) the emergence of cognitivism capitalized on the concept of representation, and that (2) the materialization of nonclassical cognitive science involves a return to some form of pre-cognitivist behaviourism. We argue against both (1) and (2), by questioning Ramsey’s divide between classical and representational, versus nonclassical and nonrepresentational, cognitive models. For, firstly, connectionist and other nonclassical accounts have the resources to exploit the notion of a structural isomorphism, like classical accounts (the beefing-up strategy); and, secondly, insofar as input–output and structural representations refer to a cognitive agent, classical explanations fail to meet the job description challenge (the deflationary strategy). Both strategies work independently of each other: if the deflationary strategy succeeds, contra (1), cognitivism has failed to capitalize on the relevant concept of representation; if the beefing-up strategy is sound, contra (2), the return to a pre-cognitivist era cancels out.

Pothos's revision of rules and similarity in the area of language illustrates the impression that the classicist/connectionist debate is in a blind alley. Under his continuum proposal, both hypotheses fall neatly within the information-processing paradigm. In my view, the paradigm shift that dynamic systems theory represents (Spencer & Thelen 2003) should be submitted to critical scrutiny. Specific formalizations of the Rules versus Similarity distinction may not lead to a form of unification under Generalized Context Models or connectionist networks.

El siguiente trabajo pretende realizar una aproximación a los conceptos de muerte y de suicidio, en tanto ideas filosóficas, en la obra del filósofo rumano Emil Cioran. Se plantea un recorrido por la obra del autor, poniendo en discusión dichas ideas a lo largo de la obra del filósofo. En Cioran, veremos cómo el suicidio se trata de una idea, mientras que la muerte es aquella posibilidad de salvación que se encuentra en la vida. Se hará presente el lirismo cioraniano (...) desde su primer libro, para denotar desde allí el diálogo posible entre las ideas de muerte y suicidio. Vale aclarar que no tratamos el suicidio como un concepto clínico / médico, sino como concepto filosófico presto a la discusión del mismo atravesado por susodichas obras. (shrink)

This paper consists of two parts. First, I shall consider two defences of Quine´s polemical Thesis of the Inscrutability of Reference put forward by Hookway, and Calvo Garzón, respectively. Then, I shall consider an extension of Quine´s succinct behavioural criteria of Radical Translationsuggested by Hintikka´s Game-Theoretical Semantics. I shall argue that Hintikka´s semantics suggest behavioural criteria which we can use to constrain perverse semantic theories. In particular, I shall try to show that whilst Hintikka´s behavioural data tells against Hookway´s proposal, (...) it reveals, nonetheless, a reason as to why my proposed perverse semantic theory enjoys the same priviledged status that a standard semantic theory is supposed toenjoy.

In this commentary I explore nonclassical connectionism as a coherent framework for evaluation in the spirit of the Newell Test. Focusing on knowledge integration, development, real-time performance, and flexible behavior, I argue that NCC's “within-theory rank ordering” would place subsymbolic modeling in a better position. Failure to adopt a symbolic level of thought cannot be interpreted as a weakness.

En un escrito de juventud de Peirce publicado en 1868 para el Journal of Speculative Philosophy, titulado “Questions Concerning Certain Faculties Claimen for Man”, el autor norteamericano intenta mostrar por qué carecemos de la capacidad para reconocer cogniciones inmediatas y por qué, a falta de tal facultad, no es posible sostener la existencia de ese tipo de cogniciones; de ahí se desprende su postura anticartesiana y antifundacionista: si no hay cogniciones inmediatas, entonces todas las cogniciones están determinadas por cogniciones previas (...) y, en consecuencia, no hay cogniciones infalibles. Esta concepción del joven Peirce según la cual toda cognición está lógica o inferencialmente determinada por una cognición previa implicaría, entonces, que toda cognición, a su vez, determinaría lógicamente a una cognición posterior. Al seguir esta tesis obtenemos, en consecuencia, una doble determinación, a saber, la de una cognición(n) siendo determinada por otra cognición(n-1) anterior, y la de esa misma cognición(n) determinando a una cognición(n+1) posterior. La tesis de la doble determinación daría lugar, por tanto, no solo a una regresión infinita de determinaciones, sino también a una progresión infinita de determinaciones. [...] Aún hoy sigue abierta la discusión acerca de si en su madurez intelectual y en los albores de su vejez Peirce continuó sosteniendo sus tesis anticartesiana y antifundacionista, de sus escritos de juventud, en relación con la determinablidad de las cogniciones previas, y si aún, en sus escritos de madurez, renunció a la tesis de la progresión infinita de determinaciones. Pero no es mi interés aquí tomar partido en esta discusión. En este escrito me concentraré solamente en dos problemas: a saber, la indeterminabilidad del significado y la explicación del error, y mostraré cómo podría ser posible enfrentarlos adoptando algunos conceptos del pragmaticismo.

This paper consists of four parts. In section 1, I shall offer a strategy to bypass a counter‐example which Gareth Evans (1975) offers against Quine’s Thesis of the Inscrutability of Reference. In section 2, I shall introduce a criterion recently pro‐duced by Crispin Wright (1997) in terms of ‘psychological simplicity’ which threatens the perverse route offered in section 1. In section 3, I shall argue that a LOT model of human cognition could motivate Wright’s criterion. In section 4, I shall (...) argue that if we instead model human cognition by a recurrent neural network, then Wright’s criterion is unmotivated. Thus I shall produce a Connectionist Defence of the Inscrutability Thesis. (shrink)

The importance of the Stability Problem in neurocomputing is discussed, as well as the need for the study of infinite networks. Stability must be the key ingredient in the solution of a problem by a neural network without external intervention. Infinite discrete networks seem to be the proper objects of study for a theory of neural computability which aims at characterizing problems solvable, in principle, by a neural network. Precise definitions of such problems and their solutions are given. Some consequences (...) are explored, in particular, the neural unsolvability of the Stability Problem for neural networks.

I argue that a dynamical framing of the emulation theory of representation may be at odds with its articulation in Grush's information-processing terms. An architectural constraint implicit in the emulation theory may have consequences not envisaged in the target article. In my view, “how the emulator manages to implement the forward mapping” is pivotal with regard to whether we have an emulation theory of representation, as opposed to an emulation theory of (mere) applied forces.

En este artículo se presentan algunas variaciones del problema del regreso epistémico de la justificación. Con base en las distinciones entre justificación proposicional y justificación doxástica, por un lado, y la diferencia entre actividad de justificar y estatus de justificación, por otro, se distinguen cuatro formas de entender el problema del regreso epistémico.

Crispin Wright has reshaped debates about Realism by offering a new landscape of what's at stake in the discussions between realists and their opponents. Instead of arguing whether a given discourse can be truth apt， discussion should focus, Wright contends, on what kind of truth predicate a discourse can enjoy. Namely, whether truth for a discourse can be 'robust' or merely ‘minimal' Wright's approach has important implications for Quine's well-known Thesis of the Inscrutability of Reference. The bulk of this paper (...) will be devoted to showing that an argument involving minimalism about truth which Wright offersagainst the Inscrutability Thesis fails by reductio. By the end of the paper, we'll see how Wright's proposed frame of' discussion for Realism bears on themetaphysical status of Semantic Theories. (shrink)

Mental health among students is one of the major concerns amidst the pandemic. Employing a correlational design, this study investigates the relationship between emotional intelligence and mental health among 152 senior high school students. Based on the statistical analysis, the r coefficient of 0.82 indicates a high positive correlation between the variables. The p-value of 0.00, which is less than 0.05, leads to the decision to reject the null hypothesis. Hence, a significant relationship exists between emotional intelligence and mental health (...) among senior high school. Implications were discussed in the study. (shrink)

Recent arguments claim that behavioral science has focused – to its detriment – on the individual over the system when construing behavioral interventions.

By studying individuals who have overcome inequality, “positive deviants,” and the system limitations they navigate, we offer potentially greater policy solutions.

The research conducted at Nuevo Rocafuerte High School evaluated the efficacy of the Movie Method, which is an app for learning English that focuses on English vocabulary development for tenth-year EFL students. Methodologically, the research integrated surveys with test performance analysis to gauge the impact of digital tools on language acquisition at the A1 proficiency level. Results demonstrated a marked preference for digital learning, with 60% of students favoring movie-based methods over traditional vocabulary learning strategies. The adaptability of the Movie (...) Method was a significant factor, reflected in its high average score for enhancing vocabulary retention and understanding of difficult words. Despite initial reductions in participation due to unfamiliarity with the method, engaged students displayed considerable gains in vocabulary comprehension and usage, affirming the potential of such applications in bolstering language proficiency. The study underscores the importance of integrating mobile technology in educational strategies and the necessity of accessible, user-centered educational resources. Further investigation is required to corroborate these findings and assess the long-term impact of digital tools in diverse educational settings. (shrink)

Tissues are shaped and patterned by mechanical and chemical processes. A key mechanical process is the positioning of the mitotic spindle, which determines the size and location of the daughter cells within the tissue. Recent force and position-fluctuation measurements indicate that pushing forces, mediated by the polymerization of astral microtubules against­ the cell cortex, maintain the mitotic spindle at the cell center in Caenorhabditis elegans embryos. The magnitude of the centering forces suggests that the physical limit on the accuracy and (...) precision of this centering mechanism is determined by the number of pushing microtubules rather than by thermally driven fluctuations. In cells that divide asymmetrically, anti-centering, pulling forces generated by cortically located dyneins, in conjunction with microtubule depolymerization, oppose the pushing forces to drive spindle displacements away from the center. Thus, a balance of centering pushing forces and anti-centering pulling forces localize the mitotic spindles within dividing C. elegans cells. We discuss microtubule-based mechanisms of the mitotic spindle positioning, a key mechanical process that shapes and patterns tissues. The magnitude of the centering forces indicates that the physical limit on the accuracy and precision of centering is set by the number of contributing microtubules rather than by thermally driven fluctuations.

Contemporary literature distinguishes two ways to defend the claim that cognition is a matter of representations: one, cognition involves representation-hungry tasks; two, cognition involves a complex form of informational covariation between subcomponents of a system with an adaptive function. Each of these conceptions involves a different notion of representation, and promotes a particular view of the architecture of cognition. But despite the differences, each of them aims to support the claim that cognition is a matter of representations on architectural constraints. (...) The objective of this article is twofold: one, it is argued that architectural constraints do not entail either of those two ways to defend the claim that cognition is a matter of representations; two, it is claimed that both notions of representation share an objectionable common element – namely, the idea of a model that grounds the representational reading– that must be abandoned, in favor of a more economical explanation in terms of causal relations, in order to get a clear view of cognition.

Los distintos intentos por aclarar el concepto de justificación epistémica han dado lugar a los más intrincados debates en la epistemología analítica contemporánea. Da cuenta de ello la controversia entre el internismo y el externismo de la justificación, y las discusiones que han surgido allí entre el fiabilismo y la epistemología de la virtud. Estas disputas han tomado un nuevo aire tras el surgimiento de la tesis de la mente extendida propuesta por Clark y Chalmers (1998), que sugiere la posibilidad (...) de conocimiento extendido más allá de la mente o el cerebro individual del sujeto. El objetivo de este capítulo es mostrar y evaluar cómo un debate que en su origen fue epistemológico ha recibido influencia de una tesis metafísica, proveniente de la filosofía de la mente. En la primera parte de este capítulo identificaremos las principales corrientes que surgieron en el marco del debate sobre el internismo y el externismo de la justificación, esto es, grosso modo, el debate acerca de si la justificación de una creencia debe estar al alcance del sujeto (internismo) o si esa justificación se determina independientemente de tal alcance (externismo). Seguidamente, abordaremos este debate desde el punto de vista del fiabilismo y la epistemología de la virtud, y finalmente presentaremos las tesis de la mente extendida y la cognición distribuida para mostrar cómo estas tesis pueden ser influyentes en las discusiones epistemológicas entre posturas internistas y externistas.

ABSTRACT The article addresses the thought of E.M. Cioran from the perspective of that vital uneasiness known as the sentiment of death. Although the term appears only in his first book, the idea cuts across his entire work given that, for Cioran, human beings intuit themselves as possessed by death at every moment of their lives. When persons are faced with a meaningless reality, dominated by radical and limiting circumstances such as pain and agony, the whole tenor of life changes until it becomes a tragic intuition of life.

El llamado “retorno de la religión” puede interpretarse como un hecho inédito, un pretexto fáctico o una enmienda. Se muestra que no se trata de lo primero, pues fue un problema político para la filosofía del siglo XX, ni de lo segundo. Consiste en un arrepentimiento implícito de la teoría política por haber asumido el secularismo y el positivismo como marco epistemológico y normativo. Este concepto conduce, además, a reformular la utopía secularista y a la emergencia de la postsecularidad.

The paper contains a conceptual analysis of “act of toleration” and the property of “being tolerant”. Being tolerant is understood as a dispositional property of persons manifested in what the author calls the “circumstances of toleration”. The main circumstances distinguished are: a tendency to prohibit a certain behaviour and the competence to determine the deontic status of the behaviour in question. An act of toleration, then, consists in not prohibiting (or cancelling the prohibition of) that behaviour. It is argued that (...) this requires the existence of two different normative systems, the “basic system”, and the “justifying system”. Acts of toleration must be based on reasons coming from the latter. This insight enables one to establish a difference between reasonable and unreasonable toleration, as well as between toleration and related concepts like indifference, acquiescence, etc. The analysis also introduces the distinction between “vertical” and “horizontal” toleration. Acceptance of this last category implies that toleration does not necessarily require hierarchical relationships between those who tolerate and those whose actions are tolerated. (shrink)
