One of the goals of computerized tutoring systems is to optimize the learning of facts. Over a hundred years of declarative memory research have identified two robust effects that can improve such systems: the spacing and the testing effect. By making optimal use of both and adjusting the system to the individual learner using cognitive models based on declarative memory theories, such systems consistently outperform traditional methods (Van Rijn, Van Maanen, & Van Woudenberg, 2009). This adjustment process is driven by (...) a continuously updated estimate of the rate of forgetting for each item and learner on the basis of the learner's accuracy and response time. In this study, we investigated to what extent these estimates of individual rates of forgetting are stable over time and across different materials. We demonstrate that they are stable over time but not across materials. Even though most theories of human declarative memory assume a single underlying rate of forgetting, we show that, in practice, it makes sense to assume different materials are forgotten at different rates. If a computerized, adaptive fact‐learning system allowed different rates of forgetting for different materials, it could adapt to individual learners more readily. (shrink)

The fields of machine learning (ML) and cognitive science have developed complementary approaches to computationally modeling human behavior. ML's primary concern is maximizing prediction accuracy; cognitive science's primary concern is explaining the underlying mechanisms. Cross-talk between these disciplines is limited, likely because the tasks and goals usually differ. The domain of e-learning and knowledge acquisition constitutes a fruitful intersection for the two fields’ methodologies to be integrated because accurately tracking learning and forgetting over time and predicting future performance based on (...) learning histories are central to developing effective, personalized learning tools. Here, we show how a state-of-the-art ML model can be enhanced by incorporating insights from a cognitive model of human memory. This was done by exploiting the predictive performance equation's (PPE) narrow but highly specialized domain knowledge with regard to the temporal dynamics of learning and forgetting. Specifically, the PPE was used to engineer timing-related input features for a gradient-boosted decision trees (GBDT) model. The resulting PPE-enhanced GBDT outperformed the default GBDT, especially under conditions in which limited data were available for training. Results suggest that integrating cognitive and ML models could be particularly productive if the available data are too high-dimensional to be explained by a cognitive model but not sufficiently large to effectively train a modern ML algorithm. Here, the cognitive model's insights pertaining to only one aspect of the data were enough to jump-start the ML model's ability to make predictions—a finding that holds promise for future explorations.

The parameters governing our behavior are in constant flux, and capturing these dynamics in cognitive models remains a challenge. We demonstrate how a mapping between ACT‐R's model of declarative memory and the linear ballistic accumulator enables efficient estimation of memory parameters from data. The resulting estimates provide a cognitively meaningful explanation for observed differences in behavior over time and between individuals.

The aim of this study was to assess attitudes of intensive care nurses to selected ethical issues related to end-of-life decisions in paediatric intensive care units. A self-administered questionnaire was distributed in 2005 to intensive care nurses at two different scientific occasions in Turkey. Of the 155 intensive care nurse participants, 98% were women. Fifty-three percent of these had intensive care experience of more than four years. Most of the nurses failed to agree about withholding (65%) or withdrawing (60%) futile (...) treatment. In addition, 68% agreed that intravenous nutrition must continue at all costs. In futile treatment cases, the nurses tended to leave the decision to parents or act maternalistically. The results showed that intensive care nurses could ignore essential ethical duties in end-of-life care. We suggest that it is necessary to educate Turkish intensive care nurses about ethical issues at the end of life. (shrink)

The parameters governing our behavior are in constant flux. Accurately capturing these dynamics in cognitive models poses a challenge to modelers. Here, we demonstrate a mapping of ACT-R's declarative memory onto the linear ballistic accumulator (LBA), a mathematical model describing a competition between evidence accumulation processes. We show that this mapping provides a method for inferring individual ACT-R parameters without requiring the modeler to build and fit an entire ACT-R model. Existing parameter estimation methods for the LBA can be used, (...) instead of the computationally expensive parameter sweeps that are traditionally done. We conduct a parameter recovery study to confirm that the LBA can recover ACT-R parameters from simulated data. Then, as a proof of concept, we use the LBA to estimate ACT-R parameters from an empirical dataset. The resulting parameter estimates provide a cognitively meaningful explanation for observed differences in behavior over time and between individuals. In addition, we find that the mapping between ACT-R and LBA lends a more concrete interpretation to ACT-R's latency factor parameter, namely as a measure of response caution. This work contributes to a growing movement towards integrating formal modeling approaches in cognitive science. (shrink)

Large changes in a scene often become difficult to notice if made during an eye movement, image flicker, movie cut, or other such disturbance. It is argued here that this _change blindness_ can serve as a useful tool to explore various aspects of vision. This argument centers around the proposal that focused attention is needed for the explicit perception of change. Given this, the study of change perception can provide a useful way to determine the nature of visual attention, and (...) to cast new light on the way that it is?and is not?involved in visual perception. To illustrate the power of this approach, this paper surveys its use in exploring three different aspects of vision. The first concerns the general nature of _seeing_. To explain why change blindness can be easily induced in experiments but apparently not in everyday life, it is proposed that perception involves a _virtual representation_, where object representations do not accumulate, but are formed as needed. An architecture containing both attentional and nonattentional streams is proposed as a way to implement this scheme. The second aspect concerns the ability of observers to detect change even when they have no visual experience of it. This _sensing_ is found to take on at least two forms: detection without visual experience (but still with conscious awareness), and detection without any awareness at all. It is proposed that these are both due to the operation of a nonattentional visual stream. The final aspect considered is the nature of visual attention itself?the mechanisms involved when _scrutinizing_ items. Experiments using controlled stimuli show the existence of various limits on visual search for change. It is shown that these limits provide a powerful means to map out the attentional mechanisms involved. (shrink)

It has often been assumed that when we use vision to become aware of an object or event in our surroundings, this must be accompanied by a corresponding visual experience (i.e., seeing). The studies reported here show that this assumption is incorrect. When observers view a sequence of displays alternating between an image of a scene and the same image changed in some way, they often feel (or sense) the change even though they have no visual experience of it. The (...) subjective difference between sensing and seeing is mirrored in several behavioral differences, suggesting that these are two distinct modes of conscious visual perception. (shrink)

This essay is an examination of how sensing capacities can draw in, and from, other-than-human entities—both animate and inanimate. Based upon ethnographic field research in Iceland, it describes sensory encounters that are realizable through the bodies, sensations, and ontological status shifts of other beings and entities, namely, in bears and ice and earth. As anthropogenic impacts deepen, the essay argues, sensing ought to be practiced as a collaborative effort among human and other-than-human entities. Sensing by other means (...) entails sensing through others’ means and beyond the human sensorium. (shrink)

This article proposes a sensory studies methodology for the interpretation of museum objects. The proposed method unfolds in two phases: virtual encounter via an on-line catalog and actual exposure in the context of a handling workshop. In addition to exploring the écart between image and object, the “Sensing Art and Artifacts” exercise articulates a framework for arriving at a multisensory, cross-cultural, interactive understanding of aesthetic value. The case studies presented here involve four objects from the collection of the Hunterian (...) Museum as sensed and interpreted by scholars of psychology, philosophy, sociology, and anthropology. It is proposed that aesthetic judgment in the expanded (cross-cultural) sense contemplated here involves apprehending the museum object through multiple sensory modalities in place of the conventional Western fixation on visible form.

After introducing the concept of compressed sensing as a complementary measurement mode to the classical Shannon-Nyquist approach, I discuss some of the drivers, potential challenges and obstacles to its implementation. I end with a speculative attempt to embed compressed sensing as an enabling methodology within the emergence of data-driven discovery. As a consequence I predict the growth of non-nomological sciences where heuristic correlations will find applications but often bypass conventional pure basic and use-inspired basic research stages due to (...) the lack of verifiable hypotheses.

Rensink [Rensink, R. A. . Visual sensing without seeing. Psychological Science, 15, 27–32] has presented evidence suggesting visual changes may be sensed without an accompanying visual experience. Here, we report two experiments in which we monitored observers’ eye-movements whilst they searched for a difference between two simultaneously presented images and pressed separate response keys when a difference was seen or sensed. We first assessed whether sensing performance was random by collecting ratings of confidence in the validity of (...) class='Hi'>sensing and assessing gaze location during sensing. Sensing was not random: fixation position and confidence ratings were different when a difference was present compared to catch trials. Furthermore, the uniformity of objects in the images and the type of difference appear to affect seeing and sensing differently, suggesting that these processes are dissociated. The possibility is discussed of a sensing mechanism that increases vigilance toward unconsciously registered differences, particularly changes to scene layout. (shrink)

Using the exemplary case of 19th-century American state penitentiaries, the authors explore penitentiary control from the perspective of sensing agents who navigate a controlled sensory ecology – the prison, as structured by institutional rules, differential power relations, and architectural plans. Moving beyond Foucault’s Discipline and Punish and Goffman’s Asylums, they stress a pragmatist approach to understanding human sensing and explain inmates’ creativity under constraints. Employing wardens’ disciplinary journals and other secondary reports, the article emphasizes three theoretical issues that (...) explain why Panoptical prisons’ attempts to control sense experiences can sometimes fail: architectural designs that inadequately negotiate the contradictory demands of visual and acoustic control; inmates’ active mobilization of perceptible objects as means of resistance; and power differences between prison authorities and inmates that prevent actors from sharing a common sensory field. The authors’ overarching goal is to advance, via pragmatism, a sensory analysis of institutional control. (shrink)

Instead of presuming the ‘observer’ as given, we are (re)sensing the observer and are thereby offering an ‘open order cybernetics’ (OOC). We are first of all concerned about our acquisition and use of language as the precondition for any meaningful statement. This self-reflexive point of departure distinguishes our project from philosophers who are presuming ‘something’ (‘closure’, ‘selforganization’, ‘self ’, ‘auto-poiesis’, ‘senses’, ‘objects’, ‘subjects’, ‘language’, ‘nervous systems’ etc.) in the first place without being aware of their presumptions i.e. that they (...) are able to already talk meaningfully about ‘something’. We are undertaking a self-reflexive loop towards our already undertaken ‘meaningful’ actions, reflecting inside our concepts on our concepts, trying to find out how our concepts about ‘something’ have come into existence. We are reflecting on our concepts through this ongoing open investigation. We are sketching the ramifications of such a self-reflexive loop for epistemology as well as for the main research areas within cognitive science (i.e. language acquisition, perception, consciousness). We are also pointing towards virtual reality in combination with the arts as an awareness aid, helping us in our self-reflexive endeavours. (shrink)

This is an explorative work on teaching. The understanding of teaching that I use in my work is that teaching is action, it happens in the present – here and now. So, while teaching refers to shorter timespans, education in this understanding refers to timespans that are of a longer duration, meaning education is communication between generations. The notion of teaching I explore draw from experiences, for my own part between nature, dog and human. These are experiences of sensing (...) where one flows through and interconnects with others, so that boundaries are difficult to discern, and hence boundaries are not the point, but rather how sensing bodies and ‘movements between’ create experiences that are constitutive of who we become both as dog and human, in/with nature. Here I am not referring this to learning, as is usual in the equation “teaching and learning”. This does not mean learning is irrelevant, but rather that it is such an encompassing concept I cannot deal with it satisfactorily in this article. Also, I go beyond what is commonly understood as learning, in terms of making a change in someone’s cognitive or emotional structures. This article explores the kind of experiences our sensing body furnish us with and how these transfer to memory, in the here and now bodies sense, and how this creates memories. I argue this is especially important to recognize in teaching, but seldom addressed. I suggest we pay more attention to these experiences of sensing and how it becomes part of individual and collective memories. To me this is a vital and integral part in all teaching, in the present.

Retrieval practice—the process of actively calling information to mind rather than passively studying materials—has been proven to be a highly effective learning strategy. However, only recently, researchers have started to examine differences between learners in terms of the optimal conditions of retrieval practice in applied educational settings. In this study (N = 118), we focus on learners with dyslexia. We compare their performance to the performance of typical learners in an adaptive retrieval practice task using both typing-based and speech-based response (...) conditions. We find that typical learners outperform learners with dyslexia when they are asked to respond by typing, but that this difference disappears when learners respond by speech. Using a mathematical model to decompose response times, we demonstrate that this typing-specific disadvantage in learners with dyslexia is mainly a consequence of processing delays, rather than poorer memory performance. These findings contribute to a better understanding of the mechanisms underlying declarative learning in dyslexia, and they can be used to tailor educational technology toward the needs of neurodiverse learners.

This editorial examines how sensing practices are transforming through proliferating sensor technologies and altered sensing relations. Rather than engage with sensing as a project of the human mind or body as usually delineated within sensory classifications, this overview of sensors and sensing practices documents how sensing entities are emerging that are composed of shifting ensembles of multiple humans and more-than-humans, environments and technologies, politics and practices. By decoupling sensing from its exclusive human orientation, the (...) editorial and collection demonstrate how reworked approaches to sensing make it possible to tune in to how involvement with environmental problems unfolds and endures. The collection asks how sensing practices might be crafted that attend to the distributed and accumulative inequalities of environmental problems and to speculate toward differential collectives for addressing environmental crisis and change.

The article discusses the relevance of sensor-technologies as media. Beyond technical affordances sensors act as agents of implementing and activating a more-than-human sensorium within encompassing technoecologies of sensation. Outlining the onto-epistemological implications of being ‘in touch with’ sensor-media, the contribution raises questions of what it means to be included in an infrastructure of sensorial interfaces - not only of tech-assisted human-to-human or human-to-machine communication, but of unmanageable processes of machine-to-machine exchange. Delineating sensors as media necessitates reflections on the temporal relations (...) that define the ‘contemporary condition’ of intensified global computation, technological interconnectedness and the ontogenesis of sensor-media milieus, their respective temporalities and concomitant aesthetics of experienced time.

It remains a standing problem how and why the first nervous systems evolved. Molecular and genomic information is now rapidly accumulating but the macroscopic organization and functioning of early nervous systems remains unclear. To explore potential evolutionary options, a coordination centered view is discussed that diverges from a standard input–output view on early nervous systems. The scenario involved, the skin brain thesis, stresses the need to coordinate muscle-based motility at a very early stage. This paper addresses how this scenario with (...) its focus on coordination also deals with sensory aspects. It will be argued that the neural structure required to coordinate extensive sheets of contractile tissue for motility provides the starting point for a new multicellular organized form of sensing. Moving a body by muscle contraction provides the basis for a multicellular organization that is sensitive to external surface structure at the scale of the animal body. Instead of thinking about early nervous systems as being connected to the environment merely through input and output, the implication developed here is that early nervous systems provide the foundation for a highly specific animal sensorimotor organization in which neural activity directly reflects bodily and environmental spatiotemporal structure. While the SBT diverges from the input–output view, it is closely linked to and supported by ongoing work on embodied approaches to intelligence to which it adds a new interpretation of animal embodiment and sensorimotor organization.

Accounting for qualia in the natural world is a difficult business, and it is worth understanding why. A close examination of several theories of mind—Behaviorism, Identity Theory, Functionalism, and Integrated Information Theory—will be discussed, revealing shortcomings for these theories in explaining the contents of conscious experience: qualia. It will be argued that in order to overcome the main difficulty of these theories the senses should be interpreted as physical detectors. A new theory, Grounded Functionalism, will be proposed, which retains multiple (...) realizability while allowing for a scientifically based approach toward accounting for qualia in the natural world.

Research and engineering in the quantum domain involve long chains of activity involving theory development, hypothesis formation, experimentation, device prototyping, device testing, and many more. At each stage multiple paths become possible, and of the paths pursued, the majority will lead nowhere.

It provides a controlled vocabulary, built out of terms that are (...) designed to be maximally comprehensible to all groups of stakeholders and across all the sub-fields of the quantum domain.

Ghost variables are variables in program languages that do not correspond to physical entities. This special issue, based on a panel on “Race as a Ghost Variable” at the 2017 Meeting of the Society for Social Studies of Science, traces ideas of “race” in particular niches of science, technology, and medicine where it is submerged and disavowed, yet wields power. Each paper is a case study exploring ghosts that emerge through the resonance among things as heterogeneous as hair patterns, hormone (...) levels, food tastes, drug use, clinic locations, proximity to disaster, job classifications, and social belonging and suspicion, all of which vibrate with meanings accumulated over long racial histories. Together, the papers further elaborate methods and analytic models for identifying the operations of race—the relations and processes that make it, the effects that it has. A chief appeal of the metaphor of the ghost is that it brings the importance of history to the fore. Ghosts are simultaneously history and the present, not just an accretion of earlier experiences, but the palimpsest left when one tries to erase them. Sometimes faint and hard to discern, sometimes rambunctious and disruptive, ghosts refuse our attempts to simply move on. (shrink)

I apply the Method of Phenomenal Contrast to examples involving aesthetic experience and sensory illusion. While the method can provide reasons to prefer one form of content hypothesis over others, it may be of no help in answering substantive questions about the nature and structure of such content. I suggest that successful application of the method can leave us with a difficult question. Why would a sensory system have the function of representing a property that it cannotdetect?

When dealing with biological communication and information, unifying concepts are necessary in order to couple the different “codes” that are being inductively “cracked” and defined at different emergent and “deemergent” levels of the biological hierarchy. In this paper I compare the type of biological information implied by genetic information with that implied in the concept of “quorum sensing” (which refers to a prokaryotic cell-to-cell communication system) in order to explore if such integration is being achieved. I use the Lux (...) operon paradigm and the Vibrio fischeri – Euprymna scolopes symbiotic partnership to exemplify the emergence of informational contexts along the biological hierarchy (from molecules to ecologies). I suggest that the biosemiotic epistemological framework can play an integrative role to overcome the limits of dyadic mechanistic descriptions when relating the different emergent levels. I also emphasise that the realisation ofbiology as being a “science of sensing” and the new importance that is being ascribed to the “context” in experimental biology corroborate past claims ofbiosemioticians about a shift from a focus on information (as a material agent of causality) towards a focus on the world of signification.

After Rachel E. Burke briefly introduces the essays presented with a focus on our contemporary relationship to modern subjectivity, Mieke Bal will make the case for the sense of presentness on an affective and sensuous level in Munch’s paintings and Flaubert’s writing by selecting a few topics and cases from the book Emma and Edvard Looking Sideways: Loneliness and the Cinematic, published by the Munch Museum in conjunction with the exhibition Emma & Edvard. It is this foregrounded presentness that not (...) only produces the ongoing thematic relevance of these works, but more importantly, the sense-based conceptualism that declares art and life tightly bound together. If neither artist eliminated figuration in favour of abstraction, they had a good reason for that. Art is not a representation of life, but belongs to it, illuminates it and helps us cope with it by sharpening our senses. As an example, a few paintings will clarify what I mean by the noun-qualifier “cinematic” and how that aesthetic explains the production of loneliness. (shrink)

When I was revising _Sensory Qualities_ there was a period of about a year when I set the manuscript aside and did other things. When I returned to it I found that certain portions of the argument had collapsed of their own weight, like an old New England barn, and could be carted off the premises without compunction. Other parts were wobbling on their foundation, while some had weathered well and seemed nice and solid. My revision strategy was simple: I (...) kept just the nice solid bits, thinking that I could go back and work on the wobbly portions later. (shrink)

The paper seeks to argue that the feeling of being part of a larger whole, considered to be a major feature of spiritual experience in some traditions, amounts to a change in the way the self is pre-reflectively understood. Further, the paper argues that some recent developments in the study of cognition support the case for such a revision in self-conception, and this can be used to build up a secular understanding of spirituality. The paper proceeds by making use of (...) Abraham Maslow's account of peak experience along with some accounts of both ancient and contemporary forms of spirituality to argue that the feeling of being part of a larger whole amounts to a significant shift from the separative self-conception implicit in everyday behavior. Subsequently, it is argued that some extant theories on cognition point at the illusory nature of separative self-conception. (shrink)

This book review is about the French translation of a book by the anthropologist Arturo Escobar that, though it has not been translated into English yet, deserves to be known by English readers. This book is quite important since it allows one to understand occidental, capitalist and modern hegemony not only as an economic domination but above all as a cultural, epistemological and ontological colonisation. Indeed, according to Escobar, this domination takes its roots in the Occident’s ontology which translates into (...) hegemonic practices that are concrete threats to the other worlds and their dwellers. Thus, Escobar highlights the deep link between ontologies and practices and argues for a new field of study he calls political ontology or ontological politics. To accompany the proposition of a shift from a universal nature to a pluriverse composed of many worlds, Escobar does not only undermine the prejudices of modernity but also puts forward the relational ontologies from indigenous communities of Latin America that concretely resist colonisation, underlining the ontological dimension of their struggles. Such a framework enables one to overcome or at least minimize the distinction between theory and practice. (shrink)

In this paper, we identify and discuss some of the ethical problems associated with digital sensors used to detect water contamination and air pollution in the United States. Such safety devices are often deployed unsystematically and with questionable efficacy, thereby structuring the life chances of people in unequal ways. Whereas most technological infrastructures are hidden from view . or at least from active awareness . until they cease to function, those infrastructures meant to monitor and/or regulate largely "invisible" public health (...) dangers resist public awareness even when they fail. Because such detection systems tend to indivi-dualize responsibility for reducing risk, the systems may normalize and perhaps exacerbate root problems of contamination and unequal exposure. One ethical challenge is to render such systems and their failures legible. (shrink)
