Kai kurios šiuolaikinio kognityvinio mokslo teorijos teigia, kad žmogaus prote veikia dvi sistemos: sistema, vykdanti greitą intuityvų mąstymą, bei sistema, vadovaujanti lėtam logiškam mąstymui. Būtų galima manyti, kad šių sistemų egzistavimą patikrinti sudėtinga. Šiame straipsnyje pateikiamas būdas palaipsniui patvirtinti šių dviejų sistemų egzistavimą. Pasitelkiamas dviejų sistemų, pasireiškiančių per mentalinių modelių teoriją, principas. Be to, laikantis Carnapo redukcijos idėjos, straipsnyje aprašomos dvi procedūros, kuriomis hipotezė patvirtinama palaipsniui. Viena iš jų tyrinėja, kaip žmogaus protas nagrinėja žmogaus proto veiklą darant išvedimus pagal modus (...) tollendo tollens. Kita hipotezė tyrinėja išvedimus iš griežtosios disjunkcijos su trimis disjunktais. (shrink)

La tarea de selección de Peter Wason presenta el problema de que un alto porcentaje de los participantes que la ejecutan ofrecen una respuesta equivocada. En este trabajo, proponemos una explicación posible de la selección mayoritaria en dicha tarea. Nuestra explicación, por una parte, asume que los participantes tienden a perfeccionar el condicional que aparece en la regla de la tarea de selección y, por otra, recurre al marco de la lógica temporal, del que toma una semántica basada en instantes (...) en el tiempo y el operador unario Next. Nuestras ideas básicas son que el participante interpreta que la regla sólo afecta a las tarjetas que muestran los términos mencionados en sus caras visibles y que el hecho de girar una tarjeta implica el tránsito a un instante posterior en el tiempo.

La teoría de la lógica mental no acepta una regla correcta en el cálculo proposicional estándar: la regla de introducción de la disyunción (esto es, la regla que permite inferir, por ejemplo, p o q de p). Esto es un problema porque esa misma teoría admite otro esquema en el que la regla está realmente implicada. Es cierto que, como ha mostrado López-Astorga, la teoría de la lógica mental puede ser actualizada de acuerdo con resultados empíricos recientes y que (...) tal actualización puede ayudar a la teoría a resolver algunas de sus dificultades. No obstante, la actualización de López-Astorga no afronta los desafíos directamente planteados por la regla de introducción de la disyunción y este trabajo pretende proceder en esa dirección. En concreto, mi tesis aquí es que todas las dificultades de la mencionada regla pueden desaparecer si no es considerada un Esquema Núcleo de la sintaxis del pensamiento humano, sino un Esquema Alimentador de la misma.

The social contracts theory claims that, in social exchange circumstances, human reasoning is not necessarily led by logic, but by certain evolved mental mechanisms that are useful for catching offenders. An emblematic experiment carried out with the intention to prove this thesis is the first experiment described by Fiddick, Cosmides, and Tooby in their paper of 2000. Lopez Astorga has questioned that experiment claiming that its results depend on an underlying conditional logical form not taken into account by Fiddick, Cosmides, (...) and Tooby. In this paper, I propose an explanation alternative to that of Lopez Astorga, which does not depend on logical forms and is based on the mental models theory. Thus, I conclude that this other alternative explanation is one more proof that the experiment in question does not demonstrate the fundamental thesis of the social contracts theory. (shrink)

Carnap and Popper proposed ways scientists have to work. According to Carnap, they should look for confirmations for hypotheses. In Popper‘s view, what is important is to try to falsify hypotheses. Cognitive science seems to prove that, in real scientific research, both activities play a role. First, people attempt to confirm hypotheses. Second, they seek examples refuting those hypotheses. This paper is intended to show that the theory of mental models can describe the mental processes involved in both tasks: confirmation (...) and falsification. It addresses the mental possibilities individuals consider in both cases. In addition, the paper reveals that, in accordance with both Carnap‘s framework and Popper‘s approach, both mental activities are related to conditional reasoning. (shrink)

It can be thought that Gorgias’ argument on the non-existence consists of three sentences, the first one being an asseveration and the other two being conditionals. However, this paper is intended to show that there is no conditional in the argument, and that the second and third sentences only appear to be so. To do that, a methodology drawn from the framework of the mental models theory is used, which seems to lead to the true logical forms of these last (...) sentences as well. (shrink)

Baratgin and colleagues have questioned certain aspects of the mental models theory related to disjunction. It is truth that, from this last theory, the paper authored by Baratgin et al. has already been responded. However, I try to further develop that response here by insisting in two important points of the theory: the role that modulation plays in it and the clear differences between its framework and standard logic. In this way, my main aim is to support to a larger (...) extent, by means of theoretical arguments based on its general approach, the idea that the objections presented in the mentioned paper do not really impact the mental models theory.

The thesis that I wish to discuss in this paper is the next: Human Sciences (Cultural Sciences according to Dilthey, Historic-Hermeneutic sciences according to Habermas) are possible as far as the method that should make all of them possible can be epistemologically justified, this method is the hermeneutic understanding of meaning, whose central point is, in fact, the hermeneutic circle. The matter is to try to justify epistemologically the hermeneutic as understanding the meaning of the own and the other ones (...) life experiences within reflexivity and reciprocity that impregnates the structure of ordinary language. In the dialogue Habermas to Dilthey, in Knowledge and Human Interests appear many arguments to this foundation. Our text will make special emphasis in the next items: distinction between natural sciences and cultural sciences, hermeneutic understanding of meaning, ordinary language and reflexivity, specificity of the hermeneutic circle, science an vital context, and, finally, we are going to make an account of the Habermas interpretation of the Dilthey start point in bases to the relationships between Historic-hermeneutic sciences and the practice interest of the knowledge.

Este trabajo tiene como objeto poner de manifiesto las claves suarecianas de la teoría de la libertad, de acuerdo con las cuales la libertad es una potencia activa de la voluntad que, si bien se muestra indiferente en el acto de elección, sin embargo, se trata de una indiferencia activa, en la medida en que el ser humano ejerce una específica causalidad por libertad que tiene su fundamento metafísico en la teoría del acto virtual. El hombre es libre porque el (...) concurso divino no determina el acto de la voluntad libre, sino que deja al libre arbitrio humano la decisión de actuar o no actuar, de hacer una cosa o su opuesta.

Valerie Plumwood introduced in "Some false laws of logic" a series of arguments on how the rules Exported Syllogism, Disjunctive Syllogism, Commutation, and Exportation are not acceptable. Based on this we define the class of Plumwood algebras - logical matrices that do not verify any of these theses. Afterwards we provide conditional variants of the characteristic matrix of the logic RM3 that are also Plumwood algebras. These matrices are given an axiomatization based on First Degree Entailment and are endowed with (...) Belnap-Dunn Semantics. Finally we provide results of Soundness and Completeness in the strong sense for each of the defined variants. (shrink)

Este artículo pretende un doble objetivo. En primer lugar, poner en valor la antropología religiosa del pensador español, Gonzalo Puente Ojea (1924-2017) que no ha contado aún con la atención académica merecida. En segundo lugar, analizar una tesis que podemos considerar como audaz en la medida que reivindica la recuperación del animismo de E. B. Tylor. Para conseguirlo, tras una breve introducción que contextualiza el problema que abordamos, se comienza por trazar una cartografía del pensamiento sobre la religión de nuestro (...) autor. A continuación, se realiza un recorrido por su lectura del animismo tyloriano, valorando sus principales tesis en correspondencia con las teorías y los resultados de la investigación etnográfica recientes. Tras esto, extendemos nuestra lectura crítica a los principales diálogos que mantuvo con autores contrarios a la teoría animista y, de forma particular, con la teoría angular de la religión de Gustavo Bueno. Se concluye con unas consideraciones finales sobre los límites de neoanimismo como hipótesis explicativa del origen de la religiosidad y su sentido en el ámbito de la concepción irreligiosa de la realidad propia de Puente Ojea.

Uno de los principales problemas de la filosofía de la psicopatología contemporánea consiste en definir qué tipo de estados mentales son aquellos que denominamos delirantes. A esto se le ha denominado el “problema tipológico de los delirios”. El principal objetivo de este artículo es examinar las principales alternativas filosóficas contemporáneas a este problema: el doxasticismo—de acuerdo con el cuál los deli-rios deben ser caracterizados como creencias—y al anti-doxasticismo—el cuál niega el estatuto doxásticos de los delirios y ofrece una caracterización alternativa. (...) Para examinar el debate, el artículo presentará las principales características de ambas posiciones y sus fundamentos. Después, examinaremos los principales argumentos esgrimidos contra el doxasticismo y las respuestas y contraargumentos por parte de las alternativas doxásticas. Finalmente, expondremos algunas cuestiones conceptua-les y desafíos abiertos relacionados con el debate y que, a nuestro juicio, deberían de marcar la hoja de ruta de los filósofos de la mente interesados en los delirios en los próximos años.

This article explores the connections between the construct of sexism and other sociodemographic and attitudinal variables, such as internalized homonegativity and heteronormative resistances, among psychology students. Both unrefined and inferential analyses were used with a representative sample of 841 psychology students from public universities in Madrid. Results showed higher levels of sexism, internalized homonegativity and low resistances to heteronormativity among groups of men, heterosexuals and conservatives. Interactions were found that showed a higher degree of hostile sexism in: heterosexual people with (...) respect to LGB and heterosexual men with respect to heterosexual women. Also, interactions were found to show a greater degree of heteronormative resistance in: LGB people with respect to heterosexuals and left-wing women with respect to right-wing women. Correlations with sexism varied according to gender identity and sexual orientation. In addition, heteronormative resistances correlated negatively with sexism, while some components of internalized homonegativity correlated positively. Political affiliation was the most frequent predictor of sexism. The results highlight the need for an intersectional approach to understanding the phenomenon of sexism. (shrink)

In this article, we analyze the relationship between the main dimensions of organizational structure (i.e., formalization, centralization, and complexity) and ecological responsiveness in a sample of 109 firms in the European air passenger transport industry. Broadly confirming our hypotheses, the results show that high formalization of routine tasks favors ecological responsiveness. Structures characterized by high decentralization and low complexity also favor ecological responsiveness. Furthermore, decentralization has a significant, positive relationship with ecological responsiveness among firms with low vertical complexity. Overall, the (...) results indicate that organizational structure plays a major role in ecological responsiveness. (shrink)

This paper describes a study about inter-understanding between Portuguese and Spanish. Based on Peano’s work, the study resorts to the logical relation of intersection between sets and applies it to words in Portuguese and Spanish meaning the same. The material is a text that is the abstract of a psychology paper. Each of the words in that text, which is written in Portuguese, is compared to its corresponding Spanish word by means of the relation of intersection. This is made by (...) considering the letters in the words to be elements in sets. The results show the potential that this methodology can have to provide percentages of inter-understanding between the two languages (and between any pair of languages). (shrink)

The suppression task challenges classical logic. Classical logic is monotonic. However, in the suppression task, an inference with the form of modus ponendo ponens is inhibited by adding a new premise. Several explanations have been given to account for this fact. The present paper indicates three of them as examples: that of the theory of mental models, that based on logic programming and closed world assumption, and that referring to Carnap's concept of state‐descriptions. Besides, the paper offers one more explanation (...) linked to Carnap's idea of reduction. It proposes sentences akin to a reduction sentence, a pair reduction, and a bilateral reduction sentence. Those sentences are related to the initial conditional in the suppression task. This proposal tries to stay within first‐order predicate logic. (shrink)

Carnap described ways to test scientific hypotheses. However, Carnap acknowledged that confirmation can never be definite. This left open the issue about the criteria to accept hypotheses. On the other hand, Wang has developed a computer program working without sufficient knowledge or resources, which makes the action of the program akin to the manner the human mind thinks. Wang’s program includes quantitative indicators that can be assigned to the frequency and the confidence of sentences. The present paper tries to link (...) both approaches. The goal is to show how quantitative indicators such as those in Wang’s program can also be attributed to scientific hypotheses. Those indicators can help make decisions about the acceptance of the hypotheses. All of this allows proposing general characteristics for a possible algorithm to decide whether a particular hypothesis is admissible. (shrink)

There is a kind of logical theses that can be a cognitive problem. They are theses that are not tautologies and people tend to accept as absolutely correct. This is the case of theses such as those of Aristotle and Boethius. This paper tries to give an explanation of the reasons why this happens. The explanation is based on the theory of mental models. However, it also resorts to modal logic and the account of the ideas presented by Lenzen. Thus, (...) relating the general framework of the theory of mental models to basic aspects of modal logic and this last account, a possible solution of the problem is proposed. (shrink)

La teoría de la disciplina formal sostiene que el estudio de las matemáticas desarrolla las habilidades lógicas de los individuos. Attridge e Inglis realizaron un experimento con el fin de comprobar si esta teoría es correcta o no. Su conclusión fue que sus resultados mostraban que, si bien las matemáticas pueden, efectivamente, mejorar las capacidades lógicas, es necesario asumir la interpretación defectuosa del condicional. Sin embargo, López-Astorga contraargumentó que eran posibles otras interpretaciones de sus resultados, que tales resultados no (...) prueban que la interpretación material del condicional no es válida y que la teoría de los modelos mentales también los puede explicar. En este trabajo, comento los problemas vinculados a las otras interpretaciones posibles propuestas por López-Astorga y trato de mostrar que la mejor opción para la interpretación de los resultados de Attridge e Inglis es asumir la teoría de la lógica mental.

This study examines some of the perceptions amongst Spanish LGBTQ+ youth during the first wave of the COVID-19 pandemic and the subsequent confinement and lockdown measures, between March and May 2020. During this time, many of these young people were forced to return to their family homes and restrict their social relations. This new situation often exposed them to forms of violence from which there was no escape, with negative consequences for their psychosocial health. The study evaluates the correlations between (...) perceived social support, burdensomeness, thwarted belongingness and the people with whom LGBTQ+ youth lived during confinement. A descriptive and multivariate analysis of variance and bivariate correlations is used to examine the responses of 394 LGBTQ+ youth, between 17 and 21 years of age, residing in Spain. Overall, the study finds that gender is key when explaining the differences between the experiences of LGBTQ+ youth, with women and non-binary individuals experiencing a greater perception of stigma in the places where they lived during the lockdown. Moreover, trans men and women and non-binary individuals reported receiving less support and a greater feeling of burdensomeness then the other participants. These results suggest that LGBTQ+ youth must be given special consideration during times of crisis, like the COVID-19 pandemic, and may benefit from intervention with an intersectional and transfeminist perspective.

ABSTRACT: The mental models theory predicts that, while conjunctions are easier than disjunctions for individuals, when denied, conjunctions are harder than disjunctions. Khemlani, Orenes, and Johnson-Laird proved that this prediction is correct in their work of 2014. In this paper, I analyze their results in order to check whether or not they really affect the mental logic theory. My conclusion is that, although Khemlani et al.'s study provides important findings, such findings do not necessarily lead to questioning or to rejecting (...) the mental logic theory. RESUMO: A teoria dos modelos mentais prevê que, enquanto as conjunções são mais fáceis do que as disjunções, para os indivíduos, quando negadas, as conjunções são mais difíceis do que as disjunções. Khemlani, Orenes e Johnson-Laird provaram que essa previsão está correta, em seu trabalho de 2014. Neste trabalho, analiso os seus resultados, a fim de verificar se eles realmente afetam a teoria da lógica mental ou não. Minha conclusão é que, embora o estudo da Khemlani, Orenes and Johnson-Laird forneça resultados importantes, tais resultados não conduzem necessariamente a minar ou rejeitar a teoria da lógica mental.

Purpose: This systematic review aimed to analyze the impact that the COVID-19 lockdown had on the amount of physical activity performed by university students.Materials and Methods: A systematic electronic search for studies providing information regarding physical activity levels pre and during COVID-19 pandemic in university students was performed up to 20th October 2020 in the databases Cochrane Library, PubMed, SPORTDiscus, and Web of Science. The risk of bias of external validity quality of included studies was assessed by means of those (...) the Newcastle-Ottawa Scale. The quality of the evidence for main outcomes was graded using the Grading of Recommendations Assessment, Development and Evaluation approach.Results and Conclusions: A total of 10 studies were selected. Physical activity levels were assessed by means of questionnaires and accelerometer. Risk of bias was regarded as low and high in six and four investigations, respectively. The quality of evidence was downgraded to low. A significant reduction of physical activity levels were observed in 9 studies. Compared to pre-lockdown values, five studies showed a reduction of light/mild physical activity between 32.5 and 365.5%, while seven studies revealed a reduction of high/vigorous physical activity between 2.9 and 52.8%. Walking, moderate, vigorous, and total physical activity levels have been reduced during the COVID-19 pandemic confinements in university students of different countries. Despite of the reductions, those who met the current minimum PA recommendations before the lockdown generally met the recommendations also during the confinements. (shrink)

La teoría de los contratos sociales es un enfoque cognitivo que apareció décadas atrás y que defiende que la mente humana se encuentra dotada con sistemas neurocognitivos evolutivos. Estos sistemas regulan diferentes situaciones sociales, por ejemplo, los intercambios y las negociaciones, y nos permiten detectar infractores de reglas o individuos que no cumplen acuerdos. En este trabajo, revisamos críticamente las tesis de este enfoque a partir de los argumentos lingüísticos de Moldovan sobre la perfección del condicional. Nuestra conclusión apunta a (...) que, si trasladamos los planteamientos de Moldovan a un plano más psicológico, podemos explicar los resultados de los experimentos que apoyan la teoría de los contratos sociales a partir del procesamiento de la información realizado por los participantes, sin necesidad de suponer sistema neurocognitivo evolutivo alguno.Social contracts theory is a cognitive approach that emerged decades ago and holds that human mind has evolved neurocognitive systems. These systems regulate different social situations, for example, exchanges and contracts, and allow detecting offenders and individuals that do not fulfill agreements. In this paper, I check critically the theses of this approach by means of the Moldovan’s linguistic arguments about conditional perfection. In this way, I conclude that, if we apply the Moldovan’s approach in a more psychological level, we can explain the outcomes of the experiments that support social contracts theory by means of the information processing made by the participants and we do not need to suppose that there are evolved neurocognitive systems.

Resumen Atendiendo a la lógica estándar, solo uno de los cinco indemostrables propuestos por Crisipo de Solos es realmente indemostrable. Sus otros cuatro esquemas son demostrables en tal lógica. La pregunta, por tanto, es: si cuatro de ellos no son verdaderamente indemostrables, por qué Crisipo consideró que sí lo eran. López-Astorga mostró que si ignoramos el cálculo proposicional estándar y asumimos que una teoría cognitiva contemporánea, la teoría de la lógica mental, describe correctamente el razonamiento humano, se puede entender (...) por qué Crisipo pensó que todos sus indemostrables eran tan básicos. No obstante, en este trabajo trato de argumentar que la teoría de la lógica mental no es el único marco que puede explicar esto. En concreto, sostengo que otra importante teoría sobre el razonamiento en el presente, la teoría de los modelos mentales, también puede ofrecer una explicación al respecto.According to standard logic, only one of the five indemonstrables proposed by Chrysippus of Soli is actually indemonstrable. The other four schemata are demonstra-ble in that logic. The question hence is, if four of them are not really indemonstrable, why Chrysippus considered them to be so. López-Astorga showed that, if we ignore standard propositional calculus and assume that a current cognitive theory, the mental logic theory, truly describes human reasoning, it can be explained why Chrysippus thought that all of his indemonstrables were so basic. However, in this paper, I try to argue that the mental logic theory is not the only framework that can account for that. In particular, I hold that another important reasoning theory at present, the mental models theory, can offer an explanation in that regard as well. (shrink)

The literature has shown that the theory of mental models is able to describe human inductive processes. That theory has been related to the structure of inductive inferences, such as Gautama’s Syllogism indicates. On the other hand, the theory of mental models has also been linked to modal system K. This paper argues that there can be a connection between Gautama’s Syllogism and system K, not in rigorous logical deductions but in describing how the human mind can work. They can (...) refer to two different moments of inductive reasoning; the rule of necessitation of K can be a key element in the second of those moments. (shrink)
