Neural decoding studies seem to show that the “private” experiences of others are more accessible than philosophers have traditionally believed. While these studies have many limitations, they do demonstrate that by capturing patterns in brain activity, we can discover a great deal about what a subject is experiencing. We present a thought experiment about a super-decoder — the Atlantis machine — and argue that given plausible assumptions, an Atlantis machine could one day be built. On the basis of this argument, (...) we then argue for the rejection of robust notions of consciousness, which have generated numerous puzzles, including puzzles about the possibility of philosophical zombies. In light of the Atlantis machine, it can be seen that robust notions of consciousness do not earn their explanatory or descriptive keep. More modest concepts of consciousness are sufficient to account for all phenomena — in both senses of the term. This kind of antirobustness about consciousness is a deflationary approach to conscious experience that differs in important ways from illusionist approaches. (shrink)

Since its introduction, multivariate pattern analysis, or ‘neural decoding’, has transformed the field of cognitive neuroscience. Underlying its influence is a crucial inference, which we call the decoder’s dictum: if information can be decoded from patterns of neural activity, then this provides strong evidence about what information those patterns represent. Although the dictum is a widely held and well-motivated principle in decoding research, it has received scant philosophical attention. We critically evaluate the dictum, arguing that it is false: decodability is (...) a poor guide for revealing the content of neural representations. However, we also suggest how the dictum can be improved on, in order to better justify inferences about neural representation using MVPA. 1Introduction 2A Brief Primer on Neural Decoding: Methods, Application, and Interpretation 2.1What is multivariate pattern analysis? 2.2The informational benefits of multivariate pattern analysis 3Why the Decoder’s Dictum Is False 3.1We don’t know what information is decoded 3.2The theoretical basis for the dictum 3.3Undermining the theoretical basis 4Objections and Replies 4.1Does anyone really believe the dictum? 4.2Good decoding is not enough 4.3Predicting behaviour is not enough 5Moving beyond the Dictum 6Conclusion.

This study decodes consumers' preference levels using a convolutional neural network in neuromarketing. The classification accuracy in neuromarketing is a critical factor in evaluating the intentions of the consumers. Functional near-infrared spectroscopy is utilized as a neuroimaging modality to measure the cerebral hemodynamic responses. In this study, a specific decoding structure, called CNN-based fNIRS-data analysis, was designed to achieve a high classification accuracy. Compared to other methods, the automated characteristics, constant training of the dataset, and learning efficiency of the proposed (...) method are the main advantages. The experimental procedure required eight healthy participants to view commercial advertisement videos of different durations. The cerebral hemodynamic responses of the participants were measured. To compare the preference classification performances, CNN was utilized to extract the most common features, including the mean, peak, variance, kurtosis, and skewness. Considering three video durations, the average classification accuracies of 15, 30, and 60 s videos were 84.3, 87.9, and 86.4%, respectively. Among them, the classification accuracy of 87.9% for 30 s videos was the highest. The average classification accuracies of three preferences in females and males were 86.2 and 86.3%, respectively, showing no difference in each group. By comparing the classification performances in three different combinations between two groups, male participants were observed to have targeted preferences for commercial advertising, and the classification performance 88.4% between “like” vs. “dislike” out of three categories was the highest. Finally, pairwise classification performance are shown as follows: For female, 86.1%, 87.4%, 85.2%, and for male 85.7, 88.4, 85.1%, respectively. (shrink)

Revised to reflect the current status of scientific and professional theory, practices, and debate across all facets of ethical decision making, this latest edition of Celia B. Fisher's acclaimed book demystifies the American Psychological Association's (APA) Ethical Principles of Psychologists and Code of Conduct. The Fifth Edition explains and puts into practical perspective the format, choice of wording, aspirational principles, and enforceability of the code. Providing in-depth discussions of the foundation and application of each ethical standard to the broad spectrum (...) of scientific, teaching, and professional roles of psychologists, this unique guide helps practitioners effectively use ethical principles and standards to morally conduct their work activities, avoid ethical violations, and, most importantly, preserve and protect the fundamental rights and welfare of those whom they serve. This edition retains and expands upon the critical content of the previous editions to help readers apply the Ethics Code to contemporary social issues in the conduct of responsible psychological science and practice.

In this note we consider Gentzen's first ordinal notation, used in his first published proof of the consistency of Peano Arithmetic. It is a decimal notation, quite different from our current notations. We give a rule to translate this notation into our usual set-theoretic notation and we show some of its peculiarities. Then we indicate how to decode Gentzen's assignment of ordinal notations to derivations and give some examples. Finally, we go through his proof of their decrease after the (...) application of his reduction procedure, giving further examples. (shrink)

This book presents a systematic design methodology for decoding the interior structure of the Antikythera mechanism, an astronomical device from ancient Greece. The historical background, surviving evidence and reconstructions of the mechanism are introduced, and the historical development of astronomical achievements and various astronomical instruments are investigated. Pursuing an approach based on the conceptual design of modern mechanisms and bearing in mind the standards of science and technology at the time, all feasible designs of the six lost/incomplete/unclear subsystems are synthesized (...) as illustrated examples, and 48 feasible designs of the complete interior structure are presented. This approach provides not only a logical tool for applying modern mechanical engineering knowledge to the reconstruction of the Antikythera mechanism, but also an innovative research direction for identifying the original structures of the mechanism in the future. In short, the book offers valuable new insights for all readers who are interested in the Antikythera mechanism. (shrink)

Speakers frequently perform representational gestures to depict concepts in an iconic fashion. For example, a speaker may hold her index finger and thumb apart to indicate the size of a matchstick. However, the process by which a physical handshape is mentally transformed into abstract spatial information is not well understood. We present a series of experiments that investigate how people decode the physical form of an articulator to derive imaginary geometrical constructs, which we call “gesture form.” We provide quantitative (...) evidence for several key properties that play a role in this process. First, “profiling,” the ability to focus on a structural subunit within the complex form of the physical hand. Second, “perspective,” for which we show that one and the same handshape seen from different perspectives can lead to different spatial interpretations. Third, “selectivity,” the fact that gestures focus on specific spatial features at the expense of others. Our results provide a first step toward mapping out the process of how representational gestures make the communication of spatial information possible. (shrink)

The principal goal of the brain-computer interface is to translate brain signals into meaningful commands to control external devices or neuroprostheses to restore lost functions of patients with severe motor disabilities. The invasive recording of brain signals involves numerous health issues. Therefore, BCIs based on non-invasive recording modalities such as electroencephalography are safer and more comfortable for the patients. The BCI requires reconstructing continuous movement parameters such as position or velocity for practical application of neuroprostheses. The BCI studies in continuous (...) decoding have extensively relied on extracting features from the amplitude of brain signals, whereas the brain connectivity features have rarely been explored. This study aims to investigate the feasibility of using phase-based connectivity features in decoding continuous hand movements from EEG signals. To this end, the EEG data were collected from seven healthy subjects performing a 2D center-out hand movement task in four orthogonal directions. The phase-locking value and magnitude-squared coherence are exploited as connectivity features along with multiple linear regression for decoding hand positions. A brute-force search approach is employed to find the best channel pairs for extracting features related to hand movements. The results reveal that the regression models based on PLV and MSC features achieve the average Pearson correlations of 0.43 ± 0.03 and 0.42 ± 0.06, respectively, between predicted and actual trajectories over all subjects. The delta and alpha band features have the most contribution in regression analysis. The results also demonstrate that both PLV and MSC decoding models lead to superior results on our data compared to two recently proposed feature extraction methods solely based on the amplitude or phase of recording signals. This study verifies the ability of PLV and MSC features in the continuous decoding of hand movements with linear regression. Thus, our findings suggest that extracting features based on brain connectivity can improve the accuracy of trajectory decoder BCIs. (shrink)

Because Arthur ‘Weegee’ Fellig’s crime scene photographs have become the standard for visually representing crime scenes in popular culture, this paper examines the extra-legal lives of two of his images, both of which were produced at the site of a gangster’s death in 1936. To decode the crime scene photograph is to interrogate the ways in which we make sense of crime through seeing and narrating. To that end, this paper charts how these two crime images were contextualized first (...) in a tabloid narrative that invited viewer identification with the law enforcer, and later in Weegee’s own autobiographical narrative as a hardboiled photographer. In contrast to these human ways of seeing and narrating, the images are then examined through computer vision. By moving across these different ways of human and nonhuman seeing, we are arrested anew by the crime scene photograph as different narrators make clear, often for different audiences, who and what it is that we are looking at. Our visual point of focus, in turn, tells us how we engage with crime images at the mediated intersection of law and popular culture; it reveals how viewers identify with the law as a result of an image’s visual structure, as well as through representational exchanges that blur the edges between fact and fiction.

The study deals with ekphraseis on works of art and poses the question as to how far these texts can be a reliable source for the study or even the reconstruction of the artefacts they describe. Based on reception theory and readerresponse criticism, in the paper is proposed that as every text, byzantine ekphraseis on artworks presuppose an audience or readership, i. e. the one the author had in mind and on the basis of which he encoded his message. In (...) order to decode this message and by extension to extract any information about the described works of art we must aim to discover their “intended reader”, and identify his or her “horizon of expectations. This proposal is tested in the study of a well known piece of this kind, Manasses’s description of a mosaic floor with a depiction of Earth. The author’s dialogue with the earlier tradition of ekphraseis, his readership’s “horizon of expectations” combined with historical facts, allow us to suppose that Manasses is describing a composition with Xenia scenes and an asarotos motif created in the early byzantine period and preserved in the Great Palace of Constantinople up to the twelfth century.

Advances in intracranial electroencephalography and neurophysiology have enabled the study of previously inaccessible brain regions with high fidelity temporal and spatial resolution. Studies of iEEG have revealed a rich neural code subserving healthy brain function and which fails in disease states. Machine learning, a form of artificial intelligence, is a modern tool that may be able to better decode complex neural signals and enhance interpretation of these data. To date, a number of publications have applied ML to iEEG, but (...) clinician awareness of these techniques and their relevance to neurosurgery, has been limited. The present work presents a review of existing applications of ML techniques in iEEG data, discusses the relative merits and limitations of the various approaches, and examines potential avenues for clinical translation in neurosurgery. One-hundred-seven articles examining artificial intelligence applications to iEEG were identified from 3 databases. Clinical applications of ML from these articles were categorized into 4 domains: i) seizure analysis, ii) motor tasks, iii) cognitive assessment, and iv) sleep staging. The review revealed that supervised algorithms were most commonly used across studies and often leveraged publicly available timeseries datasets. We conclude with recommendations for future work and potential clinical applications. (shrink)

Michel Foucault's Les Mots et les choses correctly asserts that the attempts of the human sciences of the past five hundred years to represent the world in language have failed because these sciences did not recognize the opacity or thingness of language itself. Foucault pretends to have written a plotless anti-history of the human sciences which stresses the discontinuities that characterize the succession of one "'episteme" by another. In fact, he has explained these vicissitudes by the changes of tropological strategy (...) that underlie epistemic shifts. Although he disavows the movement, Foucault's interest in revealing the poetic basis of all linguistic representations of reality places him in the eschatological wing of the structuralist establishment.

In Greg Bear’s critically acclaimed science fiction novel Darwin’s Radio, the activation of an endogenous retrovirus (SHEVA), ironically located in a “noncoding region” of the human genome, causes extreme symptoms in women worldwide, including miscarriages. In the United States, a task force is assembled to control the pandemic crisis and to find out how SHEVA operates at the genomic level. However, as the story unfolds, it becomes manifest that SHEVA is too complex to decode in this way and, moreover, (...) that it is not a disease at all. Biologist Kay Lang speculates that SHEVA is triggered by signals from the environment, and that newborn SHEVA children will be a new variation or species of Man. In this essay I analyze Bear’s literary experiment with science along Deleuze and Guattari’s important, but largely overlooked, concepts of State science and nomad science. Bear’s novel gives narrative form to nomad-scientific ideas about life, notably Lynn Margulis’s theory of endosymbiogenesis, which holds that a species’ DNA is an assemblage of many genomes acquired in symbiotic relations. The import of Bear’s informed speculations, I argue, is not crass prediction but a nomadic vision of life as always already different (impure, infected) and in becoming—a counterpoint to the image of the double helix as the bedrock of human identity. Darwin’s Radio is a key example of how fiction can be an excellent partner for science, technology, and society, analyzing and intervening in debates about life and laying bare epistemological and biopolitical tensions of technoscience.

The author explores how the discursive practices of social texts relate to the subjectivities of readers. Employing Dorothy Smith's notion of femininity as textually mediated discourse, the author analyzes how teenage girls read the depictions of femininity in the glossy advertisements of fashion magazines. Through interviews with 48 girls aged 13 to 17 years, she explores both why and how young girls negotiate “what it means to be a woman.” Most young girls in her study draw on stereotypical meanings of (...) adult femininity. By giving these stereotypes truth status, these readers valorize not only patriarchal meanings of womanhood but also naturalize associations between femininity and the commodities through which this femininity is expressed as the everyday doing of gender. The author concludes by discussing implications of this study for both a feminist theory and a feminist politics of culture. (shrink)

Little attention has been given to the integral relationship between character strengths and spirituality (the search for or communing with the sacred to derive meaning and purpose). The science of character strengths has surged in recent years with hundreds of studies, yet with minimal attention to spirituality or the literature therein. At the same time, the science of spirituality has steadily unfolded over the last few decades and has offered only occasional attention to select strengths of character (e.g., humility, love, (...) forgiveness) or the universal typology of the VIA Classification of character strengths and virtues. In this exploration, we argue that there is a robust synergy of these sciences and practices revealing that spirituality is vitally concerned with promoting character strengths. At the same time, character strengths can enhance and deepen spiritual practices, rituals, and experiences. We elaborate on how character strengths and spirituality come together in the context of the psycho-spiritual journey toward wholeness. By wholeness, we are referring to a way of being in the world, which involves a life-affirming view of oneself and the world, a capacity to see and approach life with breadth and depth and the ability to organize the life journey into a cohesive whole. We further discuss six levels by which spirituality can be integrated within the VIA Classification, including a meta-perspective in which wholeness represents a meta-strength or superordinate virtue. We frame two pathways of integration: the grounding path, in which character strengths offer tangibility and thereby deepen and enhance spirituality, and the sanctification path, in which spirituality elevates character strengths. Finally, we turn to research-based practices and examine how character strengths might facilitate and contribute to spiritual practices and, conversely, how spirituality might enhance character strength practices. Such multifaceted integration offers insight and wisdom to both areas of study and opens up new directions for psychospiritual research and practices to deepen and broaden our understanding of what it means to be human.

In various documents the view emerges that contemporary biotechnosciences are currently experiencing a scientific revolution: a massive increase of pace, scale and scope. A significant part of the research endeavours involved in this scientific upheaval is devoted to understanding and, if possible, ameliorating humankind: from our genomes up to our bodies and brains. New developments in contemporary technosciences, such as synthetic biology and other genomics and “post-genomics” fields, tend to blur the distinctions between prevention, therapy and enhancement. An important dimension (...) of this development is “biomimesis”: i.e. the tendency of novel technologies and materials to mimic or plagiarize nature on a molecular and microscopic level in order to optimise prospects for the embedding of technological artefacts in natural systems such as human bodies and brains. In this paper, these developments are read and assessed from a psychoanalytical perspective. Three key concepts from psychoanalysis are used to come to terms with what is happening in research laboratories today. After assessing the general profile of the current revolution in this manner, I will focus on a particular case study, a line of research that may serve as exemplification of the vicissitudes of contemporary technosciences, namely viral biomaterials. Viral life forms can be genetically modified (their genomes can be rewritten) in such a manner that they may be inserted in human bodies in order to produce substances at specific sites such as hormones (testosterone), neurotransmitters (dopamine), enzymes (insulin) or bone and muscle tissue. Notably, certain target groups such as top athletes, soldiers or patients suffering from degenerative diseases may become the pioneers serving as research subjects for novel applications. The same technologies can be used for various purposes ranging from therapy up to prevention and enhancement. (shrink)

Interpreting the letters characterized as written by Alice Alington and Margaret Roper in 1534 has proved perplexing since their first publication, when the editor wrote, “It is not certainly known” whether Thomas More or Roper wrote the letter to Alington. Did Roper, More, or both write it? This study looks at both letters from a variety of perspectives, pointing out many reasons that complicate reading them before focusing on the personal and political circumstances, the structural knot of wise/foolish, and the (...) writing styles of father and daughter, including an analysis of Roper's known writing, characteristically empathic. It agrees that More was the chief writer, but that Roper might well have written some, though not all, of her speeches, and that she was involved in their discussions and as More's personal representative. Finally, it suggests both letters constitute a mini-dialogue. (shrink)

This study aims to decode the hemodynamic responses evoked by multiple sound-categories using functional near-infrared spectroscopy. The six different sounds were given as stimuli. The oxy-hemoglobin concentration changes are measured in both hemispheres of the auditory cortex while 18 healthy subjects listen to 10-s blocks of six sound-categories. Long short-term memory networks were used as a classifier. The classification accuracy was 20.38 ± 4.63% with six class classification. Though LSTM networks’ performance was a little higher than chance levels, it (...) is noteworthy that we could classify the data subject-wise without feature selections. (shrink)

emerging field of nanotechnology. Nanotechnology gets its name from the nanometer, a distance of 10 -9 meters or roughly the diameter of a molecule, and the term refers to the technology for structuring matter with precise control at the nanometer scale, atom-by-atom or molecule-by-molecule, to form a pre-specified pattern. In other words, nanotechnology is the general ability to build large or small structures to complex atomic specifications.
