The studies show a positive and direct relationship between basic psychological needs satisfaction and intrinsic motivation of the students. However, there is a lack of studies that analyze the psychological processes that affect these relationships. For this reason, the purpose of this study was to investigate the mediating role of academic integration on the relationship between basic psychological needs satisfaction and intrinsic motivation of Chilean university students. The participants were a total of 580 students from a university in northern Chile, (...) 359 women and 221 men. The mediation analysis was performed by structural equations modeling, using the maximum likelihood method and the bootstrapping procedure with 10,000 iterations. The results indicated that academic integration partially mediated the relationship between basic psychological needs satisfaction and intrinsic motivation of the students. Therefore, the basic psychological needs satisfaction had an indirect effect on the intrinsic motivation of the students through academic integration. It is concluded that the academic integration constitutes a psychological process that promotes the development of intrinsic motivation for learning. The practical implications are discussed along with the limitations of the study and recommendations for future research. (shrink)

In this chapter, we discuss a selection of current views of the neural correlates of consciousness (NCC). We focus on the different predictions they make, in particular with respect to the role of prefrontal cortex (PFC) during visual experiences, which is an area of critical interest and some source of contention. Our discussion of these views focuses on the level of functional anatomy, rather than at the neuronal circuitry level. We take this approach because we currently understand more about experimental (...) evidence at this coarse level and because these results are appropriate for arbitrating between current theoretical frameworks. We discuss the Two-Visual-Systems Hypothesis (Milner & Goodale 1995; 2006), Local Recurrency (Lamme 2010; Lamme 2006), Higher Order (Lau 2008; Lau & Rosenthal 2011) and Global Workspace theories (Baars 1997; Baars 2005; Dehaene & Naccache 2001; Dehaene 2014). Despite the apparent stark differences between conscious and unconscious perceptual processing, available evidence suggests that their neural substrates must be largely shared. This indicates that the difference in neural activity between conscious and unconscious perceptual processing is likely to be subtle and highly specialized. We argue that current experimental evidence about the involvement of specific activity in prefrontal cortex supports the higher order neural theory of consciousness. In consequence, imaging techniques that focus only on marked differences between conscious and unconscious level of activity are likely to be insensitive to the relevant neural activity patterns that underlie conscious experiences. Finally, it follows from the evidence we discuss that the functional advantages of conscious over unconscious perceptual processing may be more limited than commonly thought. (shrink)

When a circular coin is rotated in depth, is there any sense in which it comes to resemble an ellipse? While this question is at the center of a rich and divided philosophical tradition (with some scholars answering affirmatively and some negatively), Morales et al. (2020, 2021) took an empirical approach, reporting 10 experiments whose results favor such perspectival similarity. Recently, Burge and Burge (2022) offered a vigorous critique of this work, objecting to its approach and conclusions on both (...) philosophical and empirical grounds. Here, we answer these objections on both fronts. We show that Burge and Burge’s critique rests on misunderstandings of Morales et al.’s claims; of the relation between the data and conclusions; and of the philosophical context in which the work appears. Specifically, Burge and Burge attribute to us a much stronger (and stranger) view than we hold, involving the introduction of “a new entity” located “in some intermediate position(s) between the distal shape and the retinal image.” We do not hold this view. Indeed, once properly understood, most of Burge and Burge’s objections favor Morales et al.’s claims rather than oppose them. Finally, we discuss several questions that remain unanswered, and reflect on a productive path forward on these issues of foundational scientific and philosophical interest. (shrink)

Arguably the most foundational principle in perception research is that our experience of the world goes beyond the retinal image; we perceive the distal environment itself, not the proximal stimulation it causes. Shape may be the paradigm case of such “unconscious inference”: When a coin is rotated in depth, we infer the circular object it truly is, discarding the perspectival ellipse projected on our eyes. But is this really the fate of such perspectival shapes? Or does a tilted coin retain (...) an elliptical appearance even when we know it’s circular? This question has generated heated debate from Locke and Hume to the present; but whereas extant arguments rely primarily on introspection, this problem is also open to empirical test. If tilted coins bear a representational similarity to elliptical objects, then a circular coin should, when rotated, impair search for a distal ellipse. Here, nine experiments demonstrate that this is so, suggesting that perspectival shapes persist in the mind far longer than traditionally assumed. Subjects saw search arrays of three-dimensional “coins,” and simply had to locate a distally elliptical coin. Surprisingly, rotated circular coins slowed search for elliptical targets, even when subjects clearly knew the rotated coins were circular. This pattern arose with static and dynamic cues, couldn’t be explained by strategic responding or unfamiliarity, generalized across shape classes, and occurred even with sustained viewing. Finally, these effects extended beyond artificial displays to real-world objects viewed in naturalistic, full-cue conditions. We conclude that objects have a remarkably persistent dual character: their objective shape “out there,” and their perspectival shape “from here.”. (shrink)

Consciousness and confidence seem intimately related. Accordingly, some researchers use confidence ratings as a measure of, or proxy for, consciousness. Rosenthal discusses the potential connections between the two, and rejects confidence as a valid measure of consciousness. He argues that there are better alternatives to get at conscious experiences such as direct subjective reports of awareness (i.e. subjects’ reports of perceiving something or of the degree of visibility of a stimulus). In this chapter, we offer a different perspective. Confidence ratings (...) in general, and metacognitive measures in particular, may offer important advantages over subjective ratings. The arguments we offer here are supported by empirical, practical and socio-strategic considerations. However, we do not suggest consciousness and confidence are interchangeable. We recognize the limitations of confidence ratings in some experimental designs and for some research questions. Nevertheless, we also address a potential conceptual link between consciousness and confidence that stems from Rosenthal’s very own work on mental quality space theory. (shrink)

Our pains can be more or less intense, our mental imagery can be more or less vivid, our perceptual experiences can be more or less striking. These degrees of intensity of conscious experiences are all manifestations of a phenomenal property I call mental strength. In this article, I argue that mental strength is a domain-general phenomenal magnitude; in other words, it is a phenomenal quantity shared by all conscious experiences that explains their degree of felt intensity. Mental strength has been (...) largely overlooked in favor of mental states’ type, representational contents, domain-specific phenomenology, or processes such as attention. Considering mental strength in our reflections about the mind illuminates debates about the relation of representational contents and phenomenal character, and it also helps address questions about the structure and functions of consciousness. Mental strength provides a unifying construct to model what is shared in the phenomenology of different types of conscious experiences. (shrink)

This work describes the perceptions that Industrial Engineering students have regarding Colombian firms’ corporate social responsibility (CSR) practices. It also explores the incidence of gender, academic level, work experience and entrepreneurial intention on students’ vision. A survey with 70 CSR practices was designed based on previous research. Practices were grouped in ten dimensions: shareholders, customers, employees, suppliers, stakeholders, ethics, environment, legal, human rights and society. A representative sample of 142 students was used. Results show that students perceive a higher commitment (...) of Colombian companies with the shareholders dimension, while a lower with the society, ethics and environmental CSR practices. Work experience and entrepreneurial intention are the only variables affecting the identified perceptions. Thus, as they gain experience, their perceptions become more favorable. On the other hand, potential entrepreneurs have a more critical view on the companies’ commitment. Additionally, the fact that the academic level does not impact students’ perceptions constitutes a challenge for the academic program, since it is expected that this will affect the vision of future engineers. This is the first study that evaluates perceptions of Industrial Engineering students, who, given their object of study, will be responsible for designing and managing production processes in organizations of the future. Results respond to a specific context (students at a Colombian public university), therefore further research to explore the subject is recommended. (shrink)

Desde la publicación de El contrato social, en 1752, la concepción roussoniana de la democracia ha sido, de diversos modos, interpretada y cuestionada. Este artículo tiene una orientación hermenéutica: busca contribuir a esclarecerla y demostrar que las interpretaciones conservadoras que la identifican con el pensamiento autoritario e incluso totalitario no corresponden al sentido de los textos. Asimismo, se explicitan sus diferencias con las concepciones políticas de Hobbes y Locke. Podría decirse que Rousseau abre el espacio para el surgimiento de nuevas (...) formas de pensamiento, respecto al liberalismo clásico y la Ilustración francesa. Fundó el pensamiento crítico sobre la sociedad moderna y planteó, lúcidamente, el problema de la fragmentación social y la necesidad de superarlo potenciando la dimensión comunitaria de la sociedad, mediante la constitución de un nuevo orden político y un nuevo proyecto educativo. Fundó, con ello, una nueva tradición democrática diferente a la de Locke: la concepción participativa de la democracia, basada en el principio de la soberanía popular, la cual ha alcanzado un importante desarrollo en nuestro tiempo.

ResumenEl estudio de las prácticas materiales de una sociedad requiere considerar los tipos de enmarcamiento epistemológico en que se desarrollan y sus efectos sobre éstas. Los modos de categorizar y distinguir y los modos organizar y agrupar son parte del enmarcamiento de las prácticas que este texto aborda. En particular, explora conceptualmente los modos de organización de conjuntos basados en la distinción agregativa entre lo singular y lo plural y los modos de organización enfocados en el efecto compositivo de la (...) diferencia entre molécula y masa. El ejercicio conceptual propone que ambos modos de organización sean empleados en conjunto, habilitando describir fenómenos de agregación y composición integrados sincrónica y diacrónicamente en la organización material de lo social.Palabras clave: agregación; composición; distinción; organización; prácticas materiales.

Sostiene el autor que las privatizaciones continúan siendo un tema central de la política latinoamericana, y que los mismos argumentos sobre su eficiencia y necesidad se repiten en todos sus países. Denuncia esto como una dependencia de las elites gobernantes latinoamericanas a “los requerimientos de la globalización”, y agrega que este no es sólo un tema ideológico, pues las privatizaciones permiten comprar a bajo precio empresas de alta rentabilidad. Analiza luego la historia de la irrupción en Chile de las privatizaciones, (...) y sus consecuencias para la economía nacional, argumentando que éstas constituyeron un instrumento fundamental del cambio de manos del poder tras el golpe de Estado de 1973, y que desde 1990 han sido una de las principales bases de lo que define como una democracia neoliberal.

Este ensayo busca mostrar la relevancia teórica, política y ética de la contribución realizada por Franz Hinkelammert a la crítica a la teoría neoliberal. Para ello, parte recorriendo algunos aspectos de la situación intelectual de los ochenta cuando el neoliberalismo fue introducido en América Latina, a continuación ofrece una caracterización general de la crítica latinoamericana al neoliberalismo, y finalmente expone algunos de los temas centrales de la contribución de Hinkelammert a dicha crítica, destacando que el centro de su refutación al (...) neoliberalismo está referida a su teoría económica. Destaca el artículo que los neoliberales han sacralizado el mercado confiriéndole los mismos atributos que la teología cristiana confiere a Dios, y que paradójicamente lo central a esta ideología es su radical antihumanismo, y su carácter de totalitarismo mercantil.

Frente a la escasa presencia del tema del estado de derecho en el pensamiento crítico latinoamericano en contraste a los de revolución, cambio social, emancipación, justicia social, democracia y derechos humanos, el autor propone la importancia de este tema en tanto la invocación al estado de derecho ha sido el mito cuasi-religioso conservador en América Latina que ha justificado la represión e incluso los golpes de estado. Por ello el artículo recoge la teoría política de Hayek, de quien sólo se (...) había enfatizado el aspecto del cambio de las concepciones económicas, escamoteando su influencia en el ámbito jurídico-político y en el de la teoría democrática. Tras ello recorre la crítica de Hinkelammert al pensamiento neoliberal. (shrink)

El presente artículo busca una posible explicación al fenómeno de rupturas en los partidos políticos chilenos en el debilitamiento de la convención colaborativa en las élites partidarias. Se considera el supuesto de que la conformación de élites partidarias corresponde a una forma de operación de los liderazgos dentro de un marco colaborativo que son los partidos. Como forma de verificar este planteamiento se analizaron tres casos de desagregaciones partidarias entre los años 2007 a 2009.

El presente artículo se sostiene que la teoría neoliberal pretende ser una interpretación verdadera de la realidad humana y social, pero a su vez contiene una utopía -en el sentido de un proyecto irrealizable, aún cuando todos estuvieran de acuerdo en intentar ponerlo en práctica; todo esto en un contexto intelectual donde tiene significativa presencia la tesis del fin de los metarelatos y de las utopías. Paradójicamente, postula el autor, la teoría neoliberal cumple las funciones de una ideología y una (...) utopía, y hasta intenta responder a las principales preguntas sobre el hombre, la libertad, el sentido de la vida humana, la sociedad y sus instituciones. El artículo recorre su historia y presenta las teorías críticas a este pensamiento, y concluye mostrando el carácter político de la utopía neoliberal. (shrink)

El artículo analiza las condiciones de validez del testimonio en ciencias sociales. Sus potencialidades centrales son el constituir un campo de exploración e investigación de acercamiento a la subjetividad, especialmente a la de los sectores populares. Ello ha permitido incorporar sus discursos y representaciones en las ciencias sociales. Sin embargo, dicha incorporación se ha realizado bajo una perspectiva empirista, según la cual el testimonio es una representación inmediata, directa de los sujetos, lo que oculta la mediación del testimonio a través (...) del cientista social, particularmente a través de la entrevista. Por ende, la idea del testimonio como una ¿voz de los sin voz¿ oculta el diálogo entre investigador-sujetos, que podría ser potenciado en un tipo de investigación hermenéutica en la que el investigador ya no ostentaría el monopolio de la interpretación.

The relevance of inner speech for human psychology, especially for higher-order cognitive functions, is widely recognized. However, the study of the phenomenology of inner speech, that is, what it is like for a subject to experience internally speaking his/her voice, has received much less attention. This study explores the subjective experience of inner speech through empathy for pain paradigm. To this end, an experimental phenomenological method was implemented. Sixteen healthy subjects were exposed to videos of sportswomen/sportsmen having physical accidents practicing (...) extreme sports. Immediately after the exposure to the stimuli, a phenomenological interview was conducted to gather data about bodily sensations, emotions, motivations, and inner speech of watching other people’s accidents. Participant’s inner speech expresses concern about the consequences the accident could generate to the sportswomen/sportsmen or about the participants themselves. Simultaneously, participants’ inner speech happened with negative emotional feelings, many sensations distributed throughout their bodies, and a felt knowledge coming from a meaningful but pre-reflective and pre-verbal bodily dimension. Our findings show that inner speech in empathy is not merely a psycholinguistic process or high-order cognitive function, but rather it is a complex experience that occurs deeply related to meaningful emotions, bodily sensations, and an implicit, somatically felt knowledge.

Introspection is a fundamental part of our mental lives. Nevertheless, its reliability and its underlying cognitive architecture have been widely disputed. Here, I propose a principled way to model introspection. By using time-tested principles from signal detection theory (SDT) and extrapolating them from perception to introspection, I offer a new framework for an introspective signal detection theory (iSDT). In SDT, the reliability of perceptual judgments is a function of the strength of an internal perceptual response (signal- to-noise ratio) which is, (...) to a large extent, driven by the intensity of the stimulus. In parallel to perception, iSDT models the reliability of introspective judgments as a function of the strength of an internal introspective response (signal-to-noise ratio) which is, to a large extent, driven by the intensity of conscious experiences. Thus, by modelling introspection after perception, iSDT can calibrate introspection’s reliability across a whole range of contexts. iSDT offers a novel, illuminating way of thinking about introspection and the cognitive processes that support it.

Metacognition is the capacity to evaluate the success of one's own cognitive processes in various domains; for example, memory and perception. It remains controversial whether metacognition relies on a domain-general resource that is applied to different tasks or if self-evaluative processes are domain specific. Here, we investigated this issue directly by examining the neural substrates engaged when metacognitive judgments were made by human participants of both sexes during perceptual and memory tasks matched for stimulus and performance characteristics. By comparing patterns (...) of fMRI activity while subjects evaluated their performance, we revealed both domain-specific and domain-general metacognitive representations. Multivoxel activity patterns in anterior prefrontal cortex predicted levels of confidence in a domain-specific fashion, whereas domain-general signals predicting confidence and accuracy were found in a widespread network in the frontal and posterior midline. The demonstration of domain-specific metacognitive representations suggests the presence of a content-rich mechanism available to introspection and cognitive control. (shrink)

Studying the neural correlates of conscious awareness depends on a reliable comparison between activations associated with awareness and unawareness. One particularly difficult confound to remove is task performance capacity, i.e. the difference in performance between the conditions of interest. While ideally task performance capacity should be matched across different conditions, this is difficult to achieve experimentally. However, differences in performance could theoretically be corrected for mathematically. One such proposal is found in a recent paper by Lamy, Salti and Bar-Haim [Lamy (...) D, Salti M, Bar-Haim Y. Neural correlates of subjective awareness and unconscious processing: an ERP study. J Cognitive Neurosci 2009,21:1435-46], who put forward a corrective method for an electroencephalography experiment. We argue that their analysis is essentially grounded in a version of High Threshold Theory, which has been shown to be inferior in general to Signal Detection Theory. We show through a series of computer simulations that their correction method only partially removes the influence of perfor- mance capacity, which can yield misleading results. We present a mathematical correction method based on Signal Detection Theory that is theoretically capable of removing performance capacity confounds. We discuss the limitations of mathemati- cally correcting for performance capacity confounds in imaging studies and its impact for theories about consciousness. (shrink)

To find the neural substrates of consciousness, researchers compare subjects’ neural activity when they are aware of stimuli against neural activity when they are not aware. Ideally, to guarantee that the neural substrates of consciousness—and nothing but the neural substrates of consciousness—are isolated, the only difference between these two contrast conditions should be conscious awareness. Nevertheless, in practice, it is quite challenging to eliminate confounds and irrelevant differences between conscious and unconscious conditions. In particular, there is an often-neglected confound that (...) is crucial to eliminate from neuroimaging studies: task performance. Unless subjects’ task performance is matched (and hence perceptual signal processing is matched), researchers risk finding the neural correlates of perception, rather than conscious perception. Here, we discuss the theoretical motivations for the performance matching framework and review empirical demonstrations of, and theoretical inferences derived from, obtaining differences in consciousness while controlling for task performance. We summarize signal detection theoretic modeling frameworks that explain how it is that we can derive performance-matched differences in consciousness without the effect being trivially driven by differences in criterion setting, and also provide principles for designing experimental paradigms that yield performance-matched differences in awareness. Finally, we address potential technical and theoretical issues that stem from matching performance across conditions of awareness, and we introduce the notion of “triangulation” for designing comprehensive experimental sets that can better reveal the neural substrates of consciousness.

When visual attention is directed away from a stimulus, neural processing is weak and strength and precision of sensory data decreases. From a computational perspective, in such situations observers should give more weight to prior expectations in order to behave optimally during a discrimination task. Here we test a signal detection theoretic model that counter-intuitively predicts subjects will do just the opposite in a discrimination task with two stimuli, one attended and one unattended: when subjects are probed to discriminate the (...) unattended stimulus, they rely less on prior information about the probed stimulus’ identity. The model is in part inspired by recent findings that attention reduces trial-by-trial variability of the neuronal population response and that they use a common criterion for attended and unattended trials. In five different visual discrimination experiments, when attention was directed away from the target stimulus, subjects did not adjust their response bias in reaction to a change in stimulus presentation frequency despite being fully informed and despite the presence of performance feedback and monetary and social incentives. This indicates that subjects did not rely more on the priors under conditions of inattention as would be predicted by a Bayes-optimal observer model. These results inform and constrain future models of Bayesian inference in the human brain. (shrink)

A recent fMRI study by Webb et al. (Cortical networks involved in visual awareness independent of visual attention, Proc Natl Acad Sci U S A 2016;113:13923–28) proposes a new method for finding the neural correlates of awareness by matching atten- tion across awareness conditions. The experimental design, however, seems at odds with known features of attention. We highlight logical and methodological points that are critical when trying to disentangle attention and awareness.

In this paper, I reject that animal reasoning, negation in particular, necessarily involves the representation of absences, as suggested by Bermúdez (2003, 2006, 2007), since this would still work as a logical negation (unavailable for non-linguistic creatures). False belief, pretense, and communication experiments show that non-human animals (at least some primates) have difficulties representing absent entities or properties. I offer an alternative account resorting to the sub-symbolic similarity judgments proposed by Vigo & Allen (2009) and expectations: animal proto-negation takes place (...) through the incompatibility between an expected and the actual representation. Finally, I propose that the expectation paradigm be extrapolated to other experi-ments in cognitive psychology (both with pre-linguistic children and animals) in order to design fair experiments that test other minds considering their true abilities.

RESUMEN Se aborda el tema de la "racionalidad" en la versión estándar del enfoque pragmadialéctico, que pretende superar la dicotomía entre los aspectos normativo y descriptivo que existe en los estudios sobre argumentación. Se señala que la pragmadialéctica, al conceptualizar su noción de racionalidad, asume explícitamente ciertos postulados popperianos y, dado que aquella también incluye elementos de Searle y Grice, se indaga si las ideas de racionalidad de estos filósofos están presentes implícitamente en el compromiso con la racionalidad. A su (...) vez, se da cuenta de algunos nexos del pensamiento aristotélico con los planteamientos de Popper, Searle y Grice con el fin de aclarar la concepción de la racionalidad que tienen los pragmadialécticos, y de estimular un regreso enriquecedor a las fuentes de la argumentación. ABSTRACT The article addresses the issue of "rationality" in the standard version of the pragma-dialectic approach, which aims at overcoming the dichotomy between the normative and descriptive aspects that are evident in studies on argumentation. It points out that when conceptualizing its notion of rationality, pragma-dialectics explicitly assumes some of Popper's postulates. Given that said conceptualization also includes elements from Searle and Grice, the paper also inquires into whether these philosophers' ideas on rationality are implicitly present in the commitment to rationality. Likewise, it discusses some connections between Aristotelian thought and the formulations of Popper, Searle, and Grice, in order to clarify the pragma-dialectic conception of rationality and foster an enriching return to the sources of argumentation.

The present paper analyses the topic of scientific discovery and the problem of the existence of a logical framework involved in such endeavour. We inquire how several non-monotonic logic frameworks and other formalisms can account for such a task. In the same vein, we analyse some key aspects of the historical and theoretical debate surrounding scientific discovery, in particular, the context of discovery and context of justification context distinction. We present an argument concerning the weakening of the discovery/justification context dichotomy (...) based on the descriptive accent contained in the non-monotonic logic perspective together with its epistemological concerns.
