A critical issue in executive control is how the nervous system exerts flexibility to inhibit a prepotent response and adapt to sudden changes in the environment. In this study, force measurement was used to capture “partial” unsuccessful trials that are highly relevant in extending the current understanding of motor inhibition processing. Moreover, a modified version of the stop-signal task was used to control and eliminate potential attentional capture effects from the motor inhibition index. The results illustrate that the non-canceled force (...) and force rate increased as a function of stop-signal delay, offering new objective indices for gauging the dynamic inhibitory process. Motor response was a function of delay in the presentation of novel/infrequent stimuli. A larger lateralized readiness potential amplitude in go and novel stimuli indicated an influence of the novel stimuli on central motor processing. Moreover, an early N1 component reflects an index of motor inhibition in addition to the N2 component reported in previous studies. Source analysis revealed that the activation of N2 originated from inhibitory control associated areas: the right inferior frontal gyrus, pre-motor cortex, and primary motor cortex. Regarding partial responses, LRP and error-related negativity were associated with error correction processes, whereas the N2 component may indicate the functional overlap between inhibition and error correction. In sum, the present study has developed reliable and objective indices of motor inhibition by introducing force, force-rate and electrophysiological measures, further elucidating our understandings of dynamic motor inhibition and error correction.

In the last 50 years, discussions of how to understand disability have been dominated by the medical and social models. Paradoxically, both models overlook the disabled person’s experience of the lived body, thus reducing the body of the disabled person to a physiological body. In this article we introduce what we call the Ecological-Enactive (EE) model of disability. The EE-model combines ideas from enactive cognitive science and ecological psychology with the aim of doing justice simultaneously to the lived experience of (...) being disabled, and the physiological dimensions of disability. More specifically, we put the EE model to work to disentangle the concepts of disability and pathology. We locate the difference between pathological and normal forms of embodiment in the person’s capacity to adapt to changes in the environment. To ensure that our discussion remains in contact with lived experience, we draw upon phenomenological interviews we have carried out with people with Cerebral Palsy. (shrink)

When one wants to use citizen input to inform policy, what should the standards of informedness on the part of the citizens be? While there are moral reasons to allow every citizen to participate and have a voice on every issue, regardless of education and involvement, designers of participatory assessments have to make decisions about how to structure deliberations as well as how much background information and deliberation time to provide to participants. After assessing different frameworks for the relationship between (...) science and society, we use Philip Kitcher's framework of Well-Ordered Science to propose an epistemic standard on how citizen deliberations should be structured. We explore what potential standards follow from this epistemic framework focusing on significance versus scientific and engineering expertise. We argue that citizens should be tutored on the historical context of why scientific questions became significant and deemed scientifically and socially valuable, and if citizens report that they are capable of weighing in on an issue then they should be able to do so. We explore what this standard can mean by looking at actual citizen deliberations tied to the 2014 NASA ECAST Asteroid Initiative Citizen forums. We code different vignettes of citizens debating alternative approaches for Mars exploration based upon what level of information seemed to be sufficient for them to feel comfortable in making a policy position. The analysis provides recommendations on how to design and assess future citizen assessments grounded in properly conveying the historical value context surrounding a scientific issue and trusting citizens to seek out sufficient information to deliberate.

Ecological psychology (EP) and the enactive approach (EA) may benefit from a more focused view of lived temporality and the underlying temporal multiscalar nature of human living. We propose multiscalar temporality (MT) as a framework that complements EP and EA, and moves beyond their current conceptualisation of timescales and inter-scale relationships in organism-environment dynamical systems. MT brings into focus the wide ranging and meshwork-like interdependencies at play in human living and the questions concerning how agents are intimately entangled in such (...) meshworks, utilising them as resources for skilful living. We develop a conceptual toolkit that highlights temporality: Firstly, we address lived temporality. We use a case study from psychotherapy to show how a person’s skilful engagement with the world is best described as adaptive harnessing of interdependencies of constraints residing across a wide range of timescales. We call this skill time-ranging. Secondly, the case study provides a proof of concept of the integration of an idiographic approach to human conversing and a more general theory of emergent organisation rooted in theoretical biology. We introduce the existing concept of constraint closure from theoretical biology and scale it up to human interactivity. The detailed conceptualisation of constraint interdependencies constitutes the backbone of the proposal. Thirdly, we present a heuristic mapping of what we call organising frames. The mapping guides the conceptualisation of the emergence of inter-scale relationships and serves as an epistemic tool that brings together nomothetic and idiographic approaches. Finally, we combine new ideas with re-interpretations of existing EP and EA concepts and elaborate on the need of a fresh new look at the implicit and sometimes missing conceptualisations of temporality in the EP and EA literature.

In this paper, we try to expose the fundamental ideas at the basis of Jorge Millas’ axiology. First, we will expose synoptically the core of the legal philosophy that the Chilean thinker develops on his works on the subject, including his conception about philosophy in general , and about legal science in particular . Secondly, we will expose the epistemological suppositions of his legal philosophy , and his consequent conception of law’s essence , the legal rule and its foundation, and (...) the axiological theory that Millas develops on the basis of the distinction and relationship between “is” and “ought” . We conclude with a critical analysis that pretends to expose the strengths and weaknesses of the legal theory of this Chilean author. (shrink)

Si a cierta doxa filosófico-ideológica en plena promoción le parece válido el caracterizar a todo Occidente como a esa civilización racionalista que arraiga en la revolución científica, filosófica y aun política que Descartes emblematizaría mejor que nadie, por poco que profundicemos en el análisis ..

In this study first we delineate an overview of the main philosophical positions on the problem of the distinction between mental acts and physical acts in man. There follows an exposition of the topic, inspired by Aristotle’s and Aquinas’s principles. Sensitive operations are physical, but in the sense of an ‘elevated body,’ thanks to a higher formal dimension, which informs the organic basis. Intellectual operations, by contrast, are completely immaterial, though they act united to the sensitive cerebral basis. Accordingly, they (...) have neurological correlations, guided by the intentional causality of the intellect. The intellectual act and its neural basis form a unique act, which is integrated by several cognitive dimensions. Our intelligence uses the brain as an intrinsic instrument, but we also need external ‘cognitive’instruments, namely written texts and computers. The intellectual development of people can be explained by the interaction of these different dimensions. (shrink)

En el presente texto me propongo mostrar cómo puede entenderse el concepto de ‘metafísica’, no como el estudio de algo “sobrenatural” o “más allá de lo físico”, sino como un estudio de segundo orden que tendría por objeto de análisis los hipotéticos principios fundamentales y modelos de dependencia de la realidad. En este sentido, más que sostener juicios taxativos acerca de lo que las cosas son o qué tipo de entidades existen, las reflexiones de la metafísica podrían entenderse como análisis (...) acerca de las condiciones necesarias y suficientes para que una teoría de primer orden explique un aspecto de la realidad —o toda ella en su conjunto— de la mejor manera posible.

Mente y mundo es un ensayo filosófico en el que se da respuesta al viejo problema de cómo se vinculan el lenguaje y el pensamiento con el mundo, pero desde una perspectiva enteramente nueva: la que en la actualidad nos proporcionan la psicología cognitiva y la neurología.
