    The projective theory of consciousness: from neuroscience to philosophical psychology.Alfredo Pereira Jr - 2018 - Trans/Form/Ação 41 (s1):199-232.
    : The development of the interdisciplinary areas of cognitive, affective and action neurosciences contributes to the identification of neurobiological bases of conscious experience. The structure of consciousness was philosophically conceived a century ago as consisting of a subjective pole, the bearer of experiences, and an objective pole composed of experienced contents. In more recent formulations, Nagel refers to a “point of view”, in which qualitative experiences are anchored, while Velmans understands that phenomenal content is composed of mental representations “projected” to (...)

  2. Consciousness and Cosmos: Building an Ontological Framework.Alfredo Pereira Jr, Chris Nunn, Greg Nixon & Massimo Pregnolato - 2018 - Journal of Consciousness Studies 25 (3-4):181-205.
    Contemporary theories of consciousness are based on widely different concepts of its nature, most or all of which probably embody aspects of the truth about it. Starting with a concept of consciousness indicated by the phrase “the feeling of what happens” (the title of a book by Antonio Damásio), we attempt to build a framework capable of supporting and resolving divergent views. We picture consciousness in terms of Reality experiencing itself from the perspective of cognitive agents. Each conscious experience is (...)

    What is Consciousness?: Towards a Preliminary Definition.Alfredo Pereira Jr & H. Ricke - 2009 - Journal of Consciousness Studies 16 (5):28-45.
    There is little or no general agreement about what researchers should focus on when studying consciousness. The most active scientific studies often use the methods of Cognitive Neuroscience and focus mainly on vision. Other aspects and contents of consciousness, namely thoughts and emotions, are much less studied, possibly leading to a biased view of what consciousness is and how it works. In this essay we describe what we call a referential nucleus, implicit in much of consciousness research. In this context, (...)

    Understanding consciousness: A collaborative attempt to elucidate contemporary theories.Alfredo Pereira Jr, J. C. W. Edwards, C. Nunn, A. Trehub & M. Velmans - 2010 - Journal of Consciousness Studies 17 (5-6):5-6.
    Nature Network Groups hosted an invited workshop on 'Theories of Consciousness' during the second semester of 2009. There were presentations by each of 15 authors active in the field, followed by debate with other presenters and invitees. A week was allocated to each of the theories proposed; general discussion threads were also opened from time to time, as seemed appropriate. We offer here an account of the principal outcomes. It can be regarded as a contemporary, 'state of the art' snapshot (...)

  7. Uma Reflexão a Respeito da Evolução Humana e a Natureza da Linguagem.Alfredo Pereira Jr - 2007 - Abstracta 3 (2):138-161.
    In this paper I discuss scientific and philosophical issues related to the interdisciplinary area of Neurolinguistics, focusing on the origin and nature of human language. What kind of evolutionary process leads to the emergence of language? I propose that this process began with the adoption of bipedalism, triggering the co-evolution of new brain structures and forms of social organization. This process created a context that favoured the emergence of articulated vocalization using a combinatorial linguistic system. The identification of sufficient conditions (...)

    Trapped ion quantum computing and the principles of logic.Alfredo Pereira Jr & Roberson Polli - 2005 - Manuscrito 28 (2):559-573.
    An experimental realization of quantum computers is composed of two or more calcium ions trapped in a magnetic quadripole. Information is transferred to and read from the ions by means of structured lasers that interact with the ions’ vibration pattern, causing changes of energy distribution in their electronic structure. Departing from an initial state when the ions are cooled, the use of lasers modifies the internal state of one ion that is entangled with the others, then changing the collective states. (...)

    What The Cognitive Neurosciences Mean To Me.Alfredo Pereira Jr - 2007 - Mens Sana Monographs 5 (1):158.
    _Cognitive Neuroscience is an interdisciplinary area of research that combines measurement of brain activity (mostly by means of neuroimaging) with a simultaneous performance of cognitive tasks by human subjects. These investigations have been successful in the task of connecting the sciences of the brain (Neurosciences) and the sciences of the mind (Cognitive Sciences). Advances on this kind of research provide a map of localization of cognitive functions in the human brain. Do these results help us to understand how mind relates (...)

    Recent advances in brain physiology and cognitive processing.Alfredo Pereira Jr, Maria Ornellas Pereira & Fábio Furlan - 2011 - Mens Sana Monographs 9 (1):183.
    The discovery of participation of astrocytes as active elements in glutamatergic tripartite synapses (composed by functional units of two neurons and one astrocyte) has led to the construction of models of cognitive functioning in the human brain, focusing on associative learning, sensory integration, conscious processing and memory formation/retrieval. We have modelled human cognitive functions by means of an ensemble of functional units (tripartite synapses) connected by gap junctions that link distributed astrocytes, allowing the formation of intra- and intercellular calcium waves (...)

    Fundamentos e aplicações da sentiômica: a ciência da capacidade de sentir.Alfredo Pereira Jr & Vinícius Jonas de Aguiar - 2023 - Trans/Form/Ação 46 (spe1):57-86.
    Sentience, defined as the unconscious capacity of having conscious feeling experiences, is a psychobiological phenomenon involving dynamic patterns of electrochemical waves in living systems. The process of feeling can be studied in two ways: a) Empirical identification and analysis of the universal temporal patterns that characterize feeling, forming a science to be called Sentiomics; b) Introspective identification and report of the variety of qualitative conscious experiences, from a first-person perspective, a study that could be called Qualiomics. Qualiomics is undoubtedly a (...)

    We conducted a philosophical analysis of economic concepts and presented a proposal for a practical approach to the issues. Economic Value is defined in relation to potential or actual economic exchanges, while Social Value is defined in relation to actions to promote people, that is, human development. In the capitalist society, there is a dissociation between the two, since Social Value is only remunerated when it has Economic Value, which leads to two types of problem: the increase in economic inequality, (...)

    Symbolic Expressions of the Human Cognitive Architecture.Enidio Ilario, Alfredo Pereira Jr & Valdir Gonzalez Paixão Jr - 2016 - Dialogue and Universalism 26 (1):107-120.
    We briefly review and discuss symbolic expressions of the cognitive architecture of the human mind/brain, focusing on the Quaternion, the Axis Mundi and the Tree of Life, and elaborate on a quaternary diagram that expresses a contemporary worldview. While traditional symbols contain vertical and horizontal dimensions related to transcendence and immanence, respectively, in the contemporary interpretation the vertical axis refers to diachronic processes as biological evolution and cultural history, while the horizontal axis refers to synchronic relations as the interactions of (...)

    What affective neuroscience means for science of consciousness.Leonardo Ferreira Almada, Alfredo Pereira Jr & Claudia Carrara-Augustenborg - 2013 - Mens Sana Monographs 11 (1):253.
    The field of affective neuroscience has emerged from the efforts of Jaak Panksepp in the 1990s and reinforced by the work of, among others, Joseph LeDoux in the 2000s. It is based on the ideas that affective processes are supported by brain structures that appeared earlier in the phylogenetic scale (as the periaqueductal gray area), they run in parallel with cognitive processes, and can influence behaviour independently of cognitive judgements. This kind of approach contrasts with the hegemonic concept of conscious (...)

    Triple-Aspect Monism and nagarjuna's Approach to Meditation.Edilene de Souza Leite & Alfredo Pereira Jr - 2018 - Simbio-Logias Revista Eletrônica de Educação Filosofia e Nutrição 10 (13):96-118.
    We review the variety of meditation practices and discuss the non-dual view of the mind and the body, proposing the concept of a Feeling Self, which is empty of essence and constituted by the dynamics of experience. This concept is consistent with the principles advanced by Nagarjuna in the Buddist Mahayana tradition and the interdisciplinary ontology of Triple-Aspect Monism. The principles of co-origination and interdependence, advanced by Nagarjuna, suggest that the conscious Self is integrated in the whole of reality. The (...)

    Lucid dreaming is an experience that occurs to some people, when they become aware that they are dreaming, during the dream itself. In this situation, they can take voluntary steps to test the limits of the dream and compare it with the agency experience they have while awake. These procedures, combined with neuroscientific studies, allow us to discuss the reality of the dream, and the reality of the experience in general. Here we present some lines of discussion that arise from (...)

    A Respiração Como Ferramenta Para a Autorregulação Psicofisiológica Em Crianças: Uma Introdução À Prática da Meditação.Marina Zuanazzi Cruz & Alfredo Pereira Jr - 2018 - Simbio-Logias Revista Eletrônica de Educação Filosofia e Nutrição 10 (13):85-95.
    Learning self-regulation skills is essential for proper neurobiological and psychosocial development in childhood. In this study, we investigated the role of breathing, considered a fundamental resource for many meditation practices, as a tool to promote self-regulation in preschool-aged children. Respiratory modulation has been used as a technique in promoting psychophysiological regulation, due to its beneficial effect on the functioning of the autonomic nervous system (ANS), to its important role in the regulation of metabolism, and for promoting the entrainment of all (...)

  20. Projecting the Trees but Ignoring the Forest: A Brief Critique of Alfredo Pereira Jr.’s Target Essay.Gregory Michael Nixon - 2018 - Trans/Form/Ação 41 (s1):269-292.
    Pereira’s “The Projective Theory of Consciousness” is an experimental statement, drawing on many diverse sources, exploring how consciousness might be produced by a projective mechanism that results both in private selves and an experienced world. Unfortunately, pulling together so many unrelated sources and methods means none gets full attention. Furthermore, it seems to me that the uncomfortable breadth of this paper unnecessarily complicates his project; in fact it may hide what it seeks to reveal. If this conglomeration of diverse (...)

    In this study I propose an epistemological discussion of multiple spatio-temporal scales in neuroscience. Are such scales merely convenient levels of description of structure and function, or do they correspond to irreducible levels of brain organization? What criteria should we employ in order to reduce one level to another, or to identify levels that are not reducible to others? Should we think of these criteria as based on empirical and/or theoretical reasons? Beginning with an empirical criterion – the necessity of (...)

    Conceptual spaces and consciousness: Integrating cognitive and affective processes.Alfredo Pereira Júnior & Leonardo Ferreira Almada - 2011 - International Journal of Machine Consciousness 3 (01):127-143.
    In the book "Conceptual Spaces: the Geometry of Thought" [2000] Peter Gärdenfors proposes a new framework for cognitive science. Complementary to symbolic and subsymbolic [connectionist] descriptions, conceptual spaces are semantic structures — constructed from empirical data — representing the universe of mental states. We argue that Gärdenfors' modeling can be used in consciousness research to describe the phenomenal conscious world, its elements and their intrinsic relations. The conceptual space approach affords the construction of a universal state space of human consciousness, (...)

    Neurobiological Underpinnings of the Projection of Conscious Contents.Alfredo Pereira - 2023 - Journal of Consciousness Studies 30 (1):21-42.
    The projection of conscious content is a central feature of Max Velmans' theory of consciousness, implying that conscious experiences are built within a conversation of minds and worlds in which they form a 'reflexive' unity – as stated in his reflexive monism theory. What are the neurobiological structures and functions that underpin the experience of conscious contents being located in a spatio-temporal frame outside the nervous system that instantiates them? In this paper I offer informed speculation about these neurobiological structures (...)

    The Global Workspace Theory (GWT) proposed by Bernard Baars (1988) along with Daniel Dennett’s (1991) Multiple Drafts Model (MDM) of consciousness are renowned cognitive theories of consciousness bearing similarities and differences. Although Dennett displays sympathy for GWT, his own MDM does not seem to be fully compatible with it. This work discusses this compatibility, by asking if GWT suffers from Daniel Dennett’s criticism of what he calls a “Cartesian Theater”. We identified in Dennett 10 requirements for avoiding the Cartesian Theater. (...)

    : This commentary focuses on the scientific status of perceptual projection-a central feature of Pereira’s projective theory of consciousness. In his target article, he draws on my own earlier work to develop an explanatory framework for integrating first-person viewable conscious experience with the third-person viewable neural correlates and antecedent causes that form conscious experience into a bipolar structure that contains both a sense of self and a sense of the world.

    A bivalent valuation is snt iff sound (standard PC inference rules take truths only into truths) and non-trivial (not all wffs are assigned the same truth value). Such a valuation is normal iff classically correct for each connective. Carnap knew that there were non-normal snt valuations of PC, and that the gap they revealed between syntax and semantics could be "jumped" as follows. Let $VAL_{snt}$ be the set of snt valuations, and $VAL_{nrm}$ be the set of normal ones. The bottom (...)
