Wearing a myoelectric prosthesis is a basic way for limb amputees to restore their lost limb functions in the activities of daily living. However, it is estimated that around 40% of amputees refuse the prosthesis. One of the primary reasons would be that the current prostheses lack appropriate sensory feedback. Currently, the amputees only depend on their visual feedback when using their arm prostheses. It would be difficult for them to accurately control the wrist position, which is vital (...) for flexible manipulation in ADLs. This manuscript designed a myoelectric arm prosthesis with wrist position feedback. To study the effect level of position feedback on prosthetic control, two tests were performed. The vibrotactile perception range test aims to analyze the perception sensitivity of the vibration in humans and obtain the optimal perception range utilized in the sensory feedback test. The sensory feedback test analyzes the effectiveness of the position feedback by comparing three feedback methods of Vis-FB, WP-FB, and a combination of Vis-FB and WP-FB. These tests were conducted by asking six able-bodied subjects to perform 20 movement combinations of five target positions. The WP-FB was transiently activated with five vibrating motors embedded in an armband to stimulate the arm stump when the prosthetic wrist rotates to the target positions. Our experimental results showed that when WP-FB was added to the prosthetic control, the absolute angular error of the prosthetic wrist declined from 4.50° to 1.08° while the success rate 3 increased from 0.34 to 0.84, respectively. This study demonstrates the importance of WP-FB to the effective control of the arm prosthesis. (shrink)

A goal of expanding life over time, space, and substrate requires that we look beneath the surface of technology and the universal norms placed on human nature to a vision of its future that could be realized. There is a visible fracturing of the personal and social behaviors of its hybrid users – a process that we might call data‐clatter. While life expansion seeks the continuation of persons over time and space and beyond the physical body, there is no current (...) method for backing up the brain and transferring its processes outside the biological system. The objectives of life expansion include developing a whole‐body prosthesis as both a device for mobility and sensory perception and a system that streams cognitive functions. These systems would provide the biosphere for biological systems of humans and the cybersphere for computational systems of digital persons. (shrink)

Many upper limb amputees experience an incessant, post-amputation “phantom limb pain” and report that their missing limbs feel paralyzed in an uncomfortable posture. One hypothesis is that efferent commands no longer generate expected afferent signals, such as proprioceptive feedback from changes in limb configuration, and that the mismatch of motor commands and visual feedback is interpreted as pain. Non-invasive therapeutic techniques for treating phantom limb pain, such as mirror visual feedback (MVF), rely on visualizations of postural changes. Advances in neural (...) interfaces for artificial sensory feedback now make it possible to combine MVF with a high-tech “rubber hand” illusion, in which subjects develop a sense of embodiment with a fake hand when subjected to congruent visual and somatosensory feedback. We discuss clinical benefits that could arise from the confluence of known concepts such as MVF and the rubber hand illusion, and new technologies such as neural interfaces for sensory feedback and highly sensorized robot hand testbeds, such as the “BairClaw” presented here. Our multi-articulating, anthropomorphic robot testbed can be used to study proprioceptive and tactile sensory stimuli during physical finger-object interactions. Conceived for artificial grasp, manipulation, and haptic exploration, the BairClaw could also be used for future studies on the neurorehabilitation of somatosensory disorders due to upper limb impairment or loss. A remote actuation system enables the modular control of tendon-driven hands. The artificial proprioception system enables direct measurement of joint angles and tendon tensions while temperature, vibration, and skin deformation are provided by a multimodal tactile sensor. The provision of multimodal sensory feedback that is spatiotemporally consistent with commanded actions could lead to benefits such as reduced phantom limb pain, and increased prosthesis use due to improved functionality and reduced cognitive burden.

This abstract presents a novel brain-computer interface (BCI) framework to control a prosthetic leg, for the rehabilitation of patients suffering from locomotive disorders, using functional near-infrared spectroscopy (fNIRS). fNIRS signals corresponding to walking intention and rest are used to initiate and stop the gait cycle and a nonlinear proportional derivative computed torque controller (PD-CTC) with gravity compensation is used to control torques of hip and knee joints for minimization of position error. The brain signals of walking intention and rest tasks (...) are acquired from primary motor cortex in the left hemisphere for nine subjects. After acquiring brain signals, in order to remove motion artifacts and physiological noises, the performance of six different filters i.e. Kalman, Wiener, Gaussian, hemodynamic response filter (hrf), Band-pass and finite impulse response, is evaluated. Afterwards, six different features are extracted from oxygenated hemoglobin signals and their different combinations were used for classification. The classification performance of five different classifiers i.e. artificial neural network, quadratic discriminant analysis, linear discriminant analysis (LDA), Naïve Bayes and support vector machine (SVM) is used. The classification accuracies obtained from SVM using hrf filter are significantly higher (p < 0.005) than the other combinations of classifier and filters. These accuracies are 77.5%, 72.5%, 68.3%, 74.2%, 73.3%, 80.8%, 65%, 76.7%, and 86.7% for all nine subjects. The control commands generated using classifier initiate and stop the gait cycle of the prosthetic leg whose knee and hip torques are controlled using PD-CTC to minimize position error. The proposed scheme can be effectively used for neurofeedback training and rehabilitation of lower limb amputation of paralyzed patients. (shrink)

Sensory substitution devices are a type of sensory prosthesis that (typically) convert visual stimuli transduced by a camera into tactile or auditory stimulation. They are designed to be used by people with impaired vision so that they can recover some of the functions normally subserved by vision. In this chapter we will consider what philosophers might learn about the nature of the senses from the neuroscience of sensory substitution. We will show how sensory substitution devices work by exploiting the (...) cross-modal plasticity of sensory cortex: the ability of sensory cortex to pick up some types of information about the external environment irrespective of the nature of the sensory inputs it is processing. We explore the implications of cross-modal plasticity for theories of the senses that attempt to make distinctions between the senses on the basis of neurobiology. (shrink)

Nanotechnology, the emerging capability of human beings to observe and organize matter at the atomic level, has captured the attention of the federal government, science and engineering communities, and the general public. Some proponents are referring to nanotechnology as “the next technological revolution”. Applications projected for this new evolution in technology span a broad range from the design and fabrication of new membranes, to improved fuel cells, to sophisticated medical prosthesis techniques, to tiny intelligent machines whose impact on (...) humankind is unknowable. As with the appropriation of technological innovation generally, nanotechnology is likely to eventually bring dramatic and unpredictable new capabilities to human material existence, along with resulting ethical challenges and social changes to be reconciled. But as of yet, aside from a few simple new consumer goods, such as paint, rackets and fabric coatings, nanotechnology is undeveloped. Its social and ethical dimensions are not apparent. Even still, given the stated goals of the various nanotechnology initiatives to rearrange matter with increasing atomic precision, the impact of nanotechnology on human life and society is likely be profound. It is very difficult, however, to make accurate predictions about the future impact of nanotechnology development on humanity. At this time, the most important role for ethics analysis is to contribute to a humanitarian, conscientious approach to its development. This paper suggests that such an approach requires that attention be given to the roles of imagination, meaning-making, metaphor, myth and belief. (shrink)

In this paper, we explore digitally fabricated aesthetic enhancements and modifications of the body as well as digitally fabricated fauna habitats. We will address how we utilize speculative works through our bio inspired digitally fabricated designs via two of our most recent projects: {skin} D.E.E.P. and in silico et in situ. Through these two projects we explore cultural implications of the intersection of technology and biologically inspired art/design. Technology has provided an ever increasing amount of data which has facilitated (...) the way data can be used in aesthetic explorations. Technology can redefine the human experience by enhancing our senses, experiences, and forms of expression. In our work {skin} D.E.E.P., we explore these ideas via augmentation through wearables and biomimetic expressions on the skin through digitally fabricated prosthetics. {skin} D.E.E.P. employs temporary biomimetic skin patterns via wearable 3D printed exoskeletons. The first series of this work mimics the patterns and textures of animal skin via ephemeral impressions onto human skin. Taking inspiration from shedding snakeskin, we shed the outer layer by removing the 3D printed prosthesis. The epidermis retains the negative imprint of the prosthetic mimicking the look of serpent skin. The dermis reestablishes the smooth form of the human skin as it heals itself within the hour, erasing the ephemeral imprint, symbolically representing rebirth and renewal. Investigating the ephemeral aesthetic of textured patterns on human skin will not by any means provide a solution to an engineering problem, yet acts as a larger philosophical basis to conduct a discussion about the possibilities of blending bio inspired designs. The manifestation of data into physical form occurs via digital fabrication in our most recent series in silico et in situ: fauna habitats in the age of voxels, where we aim to create a new ecosystem for animals and to potentially augment their habitat. The habitats include pollinator waterers, spider habitats and turtle basking platforms. This project pushes forward with a new piece—the development of a 20-foot avian sculpture that will solely exist to support the habitat of the Chimney Swift species. The Chimney Swift is a near-threatened bird species in the US. in silico et in situ investigates the interplay of art, nature and technology by contextualizing sculptural works and placing these sculptures into nature. The project serves as a breeding ground for a larger dialogue about nature, culture, human intervention, design art and technology. Providing the artwork in the public sphere, barrier free in nature, fosters this discourse. (shrink)

Assistive Device Art derives from the integration of Assistive Technology and Art, involving the mediation of sensorimotor functions and perception from both, psychophysical methods and conceptual mechanics of sensory embodiment. This paper describes the concept of ADA and its origins by observing the phenomena that surround the aesthetics of prosthesis-related art. It also analyzes one case study, the Echolocation Headphones, relating its provenience and performance to this new conceptual and psychophysical approach of tool design. This ADA tool is (...) designed to aid human echolocation. They facilitate the experience of sonic vision, as a way of reflecting and learning about the construct of our spatial perception. Echolocation Headphones are a pair of opaque goggles which disable the participant’s vision. This device emits a focused sound beam which activates the space with directional acoustic reflection, giving the user the ability to navigate and perceive space through audition. The directional properties of parametric sound provide the participant a focal echo, similar to the focal point of vision. This study analyzes the effectiveness of this wearable sensory extension for aiding auditory spatial location in three experiments; optimal sound type and distance for object location, perceptual resolution by just noticeable difference, and goal-directed spatial navigation for open pathway detection, all conducted at the Virtual Reality Lab of the University of Tsukuba, Japan. The Echolocation Headphones have been designed for a diverse participant base. They have both the potential to aid auditory spatial perception for the visually impaired and to train sighted individuals in gaining human echolocation abilities. Furthermore, this Assistive Device artwork instigates participants to contemplate on the plasticity of their sensorimotor architecture. (shrink)

Recent efforts in soft robotics and Artificial Life are attempting to construct homeostatically functioning machines with ‘feeling’ analogues. Such robots are designed to be ‘vulnerable’ and, thus, depart from traditional approaches to machine design and construction. In this paper, I explore a representative proposal by Antonio Damasio and Kingson Man, and ask how we can understand the deconstruction of ‘life’ in Derrida, Stiegler, Malabou and Wills to relate to such efforts. I argue that the adoption of biological and phenomenological (...) principles in machine design calls for attention to the precise extent that it may not result in robots that adhere either to biological or to mechanical models. It is with this admission, of the essentially unknowable character of what may result from these efforts, that deconstruction can assist roboticists and synthetic biologists today. (shrink)

Information management systems improve the retention of information in large collections. As such they act as memory prostheses, implying an ideal basis in human memory models. Since humans process information by association, and situate it in the context of space and time, systems should maximize their effectiveness by mimicking these functions. Since human attentional capacity is limited, systems should scaffold cognitive efforts in a comprehensible manner. We propose the Principles of Mnemonic Associative Knowledge (P-MAK), which describes a framework for semantically (...) identifying, organizing, and retrieving information, and for encoding episodic events by time and stimuli. Inspired by prominent human memory models, we propose associative networks as a preferred representation. Networks are ideal for their parsimony, flexibility, and ease of inspection. Networks also possess topological properties—such as clusters, hubs, and the small world—that aid analysis and navigation in an information space. Our cognitive perspective addresses fundamental problems faced by information management systems, in particular the retrieval of related items and the representation of context. We present evidence from neuroscience and memory research in support of this approach, and discuss the implications of systems design within the constraints of P-MAK’s principles, using text documents as an illustrative semantic domain.

Therapeutic strategies capable of inducing and enhancing prosthesis embodiment are a key point for better adaptation to and acceptance of prosthetic limbs. In this study, we developed a training protocol using an EMG-based human-machine interface that was applied in the preprosthetic rehabilitation phase of people with amputation. This is a case series with the objective of evaluating the induction and enhancement of the embodiment of a virtual prosthesis. Six men and a woman with unilateral transfemoral traumatic amputation without (...) previous use of prostheses participated in the study. Participants performed a training protocol with the EMG-based HMI, composed of six sessions held twice a week, each lasting 30 mins. This system consisted of myoelectric control of the movements of a virtual prosthesis immersed in a 3D virtual environment. Additionally, vibrotactile stimuli were provided on the participant’s back corresponding to the movements performed. Embodiment was investigated from the following set of measurements: skin conductance response, crossmodal congruency effect, ability to control the virtual prosthesis, and reports before and after the training. The increase in the skin conductance response in conditions where the virtual prosthesis was threatened, recalibration of the peripersonal space perception identified by the crossmodal congruency effect, ability to control the virtual prosthesis, and participant reports consistently showed the induction and enhancement of virtual prosthesis embodiment. Therefore, this protocol using EMG-based HMI was shown to be a viable option to achieve and enhance the embodiment of a virtual prosthetic limb. (shrink)

Recently, bioethicists and the UNCRPD have advocated for supported medical decision-making on behalf of patients with intellectual disabilities. But what does supported decision-making really entail? One compelling framework is Anita Silvers and Leslie Francis’ mental prosthesis account, which envisions supported decision-making as a process in which trustees act as mere appendages for the patient’s will; the trustee provides the cognitive tools the patient requires to realize her conception of her own good. We argue that supported decision-making would be better (...) understood as a collaborative process, giving patients with intellectual disabilities the opportunity to make decisions in a respectful relationship with trusted others. We offer an alternative account of supported decision-making where the primary constraint is to protect the patient from domination by the trustee. This is advantageous in its preservation of the prospects for genuine collaboration, for the mental prosthesis approach ultimately reinforces a problematic ideal of isolated patient self-determination.

This Element analyzes the various forms that design arguments for the existence of God can take, but the main focus is on two such arguments. The first concerns the complex adaptive features that organisms have. Creationists who advance this argument contend that evolution by natural selection cannot be the right explanation. The second design argument - the argument from fine-tuning - begins with the fact that life could not exist in our universe if the constants found in the (...) laws of physics had values that differed more than a little from their actual values. Since probability is the main analytical tool used, the book provides a primer on probability theory. (shrink)

Psychogenic depersonalization is an altered mental state consisting of an unusual discontinuity in the phenomenological perception of personal being; the individual is engulfed by feelings of unreality, self-detachment and unfamiliarity in which the self is felt to lack subjective perspective and the intuitive feeling of personal embodiment. A new sub-feature of depersonalization is delineated. 'Prosthesis' consists in the thought that the thinker is a 'mere thing'. It is a subjectively realized sense of the specific and objective 'thingness' of the (...) particular object thought about. I show that prosthesis is an important cognitive feature of depersonalization, and may be psychologically connected with the tendency of depersonalized individuals to report 'philosophical' types of thinking. Indeed, several philosophical issues concerning the identity of the self appear to have been enhanced by prosthesis experiences. Thus, far more efficient than William James's experimental attempts to uncover philosophical truths under the influence of nitrous oxide intoxication, prosthesis may be a safe and recommended experience for philosophers. The history of depersonalization theories is presented from Krishaber to Freud, and the main approaches to prosthesis criticized. Finally, a fresh approach to psychogenic depersonalization is outlined on the basis of certain cognitive similarities with visual agnosia. This paper may be understood as continuing the Jamesian tradition 'experimental abnormal psychology', that is, of examining extraordinary mental states with an eye to their philosophical implications.

Design thinking in general, and optimality modeling in particular, have traditionally been associated with adaptationism—a research agenda that gives pride of place to natural selection in shaping biological characters. Our goal is to evaluate the role of design thinking in non-evolutionary analyses. Specifically, we focus on research into abstract design principles that underpin the functional organization of extant organisms. Drawing on case studies from engineering-inspired approaches in biology we show how optimality analysis, and other design-related methods, (...) play a specific methodological role that is tangential to the study of adaptation. To account for the role of these reasoning strategies in contemporary biology, we therefore suggest a reevaluation of the connection between design thinking and adaptationism. (shrink)

One of the primary, if not most critical, difficulties in the design and implementation of autonomous systems is the black-boxed nature of the decision-making structures and logical pathways. How human values are embodied and actualised in situ may ultimately prove to be harmful if not outright recalcitrant. For this reason, the values of stakeholders become of particular significance given the risks posed by opaque structures of intelligent agents (IAs). This paper explores how decision matrix algorithms, via the belief-desire-intention model (...) for autonomous vehicles, can be designed to minimize the risks of opaque architectures. Primarily through an explicit orientation towards designing for the values of explainability and verifiability. In doing so, this research adopts the Value Sensitive Design (VSD) approach as a principled framework for the incorporation of such values within design. VSD is recognized as a potential starting point that offers a systematic way for engineering teams to formally incorporate existing technical solutions within ethical design, while simultaneously remaining pliable to emerging issues and needs. It is concluded that the VSD methodology offers at least a strong enough foundation from which designers can begin to anticipate design needs and formulate salient design flows that can be adapted to the changing ethical landscapes required for utilisation in autonomous vehicles.

Many attempts to define depiction appeal to viewers' perceptual responses. Such accounts are liable to give a central role in determining depictive content to picture features responsible for the response, design. A different project is to give a compositional semantics for depictive content. Such attempts identify syntax: picture features systematically responsible for the content of the whole. Design and syntax are competitors. But syntax requires system, in how picture features contribute to content, that design does not. By (...) examining John Kulvicki's semantics for basic depictive content, I argue that the relevant systematicity is absent from the pictorial realm. (shrink)

This paper describes the role of information architecture in the design of socially sustainable pervasive information spaces. The framing of information architecture as an essential part of Design Thinking extends current and historic notions of the field of information architecture. The discussion introduces the notion of the ‘contrived ontology’ which can be understood as the intentional meaning that design infuses in its artefacts, services and systems. Further, we argue that contrived ontology aligns with central themes within humanistic (...) frameworks which view reality as subjective construct. This forms the central theoretical meditation herein: we contend that while design is always an act of interpreted cultural determination, at the scale of Floridi’s infosphere, the immediacy and immersive social reality of technology will become frictionless within our human experience. As this occurs, there is a moral and ethical imperative to ensure social sustainability and to this end that the meanings and intentions that inform the mature design of our human-made world are visible and accountable. It is towards this end that information architecture can make a valuable contribution. (shrink)

The aim of the paper is to show the way in which human cognitive system uses external prostheses. Currently developed technologies provide human beings with tools that change their way of functioning in the environment, their understanding and the perspective from which they perceive the world. Modifying systems of thoughts, reasoning and modes of operation non­‑biological prostheses extend human cognitive system. A human being uses non­‑biological interfaces for processing information from the external world.

Background Over the last decades, the neurosciences, behavioral sciences, and the social sciences have all seen a rapid development of innovative research methods. The field of bioethics, however, has trailed behind in methodological innovation. Despite the so-called “empirical turn” in bioethics, research methodology for project development, data collection and analysis, and dissemination has remained largely restricted to surveys, interviews, and research papers. We have previously argued for a “Design Bioethics” approach to empirical bioethics methodology, which develops purpose-built methods for (...) investigation of bioethical concerns. In this paper we compare a research tool created using a design bioethics approach to a “methods-as-usual” approach in empirical bioethics. Methods Our study compared dimensions of engagement with a digital game we created, called “Tracing Tomorrow,” to a standard vignette survey. The two tools investigated the same subject matter, digital phenotyping for mental health, in a sample of 301 UK adolescents. Results Participants who played the game reported a greater sense of presence, emotional engagement, cognitive absorption, and mental health ethics insight, compared to participants who completed the vignette survey. Perceived authenticity and curiosity/motivation to learn more was equivalent for both methods. Conclusion The results of this study highlights the importance of purpose-built methodology for empirical bioethics research. (shrink)

We propose four policies of ethical design of human-grade Artificial Intelligence. Two of our policies are precautionary. Given substantial uncertainty both about ethical theory and about the conditions under which AI would have conscious experiences, we should be cautious in our handling of cases where different moral theories or different theories of consciousness would produce very different ethical recommendations. Two of our policies concern respect and freedom. If we design AI that deserves moral consideration equivalent to that of (...) human beings, that AI should be designed with self-respect and with the freedom to explore values other than those we might impose. We are especially concerned about the temptation to create human-grade AI pre-installed with the desire to cheerfully sacrifice itself for its creators’ benefit. (shrink)

Is it possible to advance democracy by empowering ordinary citizens to make key decisions about the design of political institutions and policies? In 2004, the government of British Columbia embarked on a bold democratic experiment: it created an assembly of 160 near-randomly selected citizens to assess and redesign the province's electoral system. The British Columbia Citizens' Assembly represents the first time a citizen body has had the power to reform fundamental political institutions. It was an innovative gamble that has (...) been replicated elsewhere in Canada and in the Netherlands, and is gaining increasing attention in Europe as a democratic alternative for constitution-making and constitutional reform. In the USA, advocates view citizens' assemblies as a means for reforming referendum processes.

The recent corporate scandals in the United States have caused a renewed interest and focus on teaching business ethics. Business schools and their faculties are reexamining the teaching of business ethics and are reassessing their responsibilities to produce honest and truthful managers who live lives of integrity and ethical accountability. The authors recognize that no agreement exists among business schools and their faculties regarding what should be the content and pedagogy of a course in business ethics. However, the authors hold (...) that regardless of one’s biases regarding the content and pedagogy, the effective teaching of business ethics requires that the instructor in designing and delivering a business ethics course needs to focus particular attention on four principal questions: (1) what are the objectives or targeted learning outcomes of the course?

(3) what learning processes need to be employed to achieve the goals? and (4) what are the roles of the participants in the learning experience? The answers to these questions provide the foundations for any business ethics course. The answers are major determinants of the impact of a business ethics course on the thinking of students and the views on the ethical and professional accountabilities and responsibilities of managers in the workplace.

Experimental design is one aspect of a scientific method. A well-designed, properly conducted experiment aims to control variables in order to isolate and manipulate causal effects and thereby maximize internal validity, support causal inferences, and guarantee reliable results.

Experimental methods are also endorsed as the most reliable guides to policy effectiveness.

This chapter discusses a version of the descriptive account of content which is compatible with rigidity thesis (RT) and critiques of RT. The rigidity of proper names demonstrates that utterances of sentences containing proper names, and utterances of sentences differing from those sentences only in containing non‐rigid descriptions in place of the proper names, differ in content. The fact that natural‐language proper names are rigid designators is an empirical discovery about natural language. The chapter intends to be a survey of (...) both the background and contemporary discussion of this discovery. However, the survey takes place in the context of an evaluation of the extent to which the discovery that English proper names are rigid itself threatens the descriptive picture of the content of names. The goal is to show that the exact philosophical significance of the discovery that natural‐language proper names are rigid designators is still, and should still be, a matter of controversy.

BackgroundImplementation science research, especially when using participatory and co-design approaches, raises unique challenges for research ethics committees. Such challenges may be poorly addressed by approval and governance mechanisms that were developed for more traditional research approaches such as randomised controlled trials.DiscussionImplementation science commonly involves the partnership of researchers and stakeholders, attempting to understand and encourage uptake of completed or piloted research. A co-creation approach involves collaboration between researchers and end users from the onset, in question framing, research design (...) and delivery, and influencing strategy, with implementation and broader dissemination strategies part of its design from gestation. A defining feature of co-creation is its emergent and adaptive nature, making detailed pre-specification of interventions and outcome measures impossible. This methodology sits oddly with ethics committee protocols that require precise pre-definition of interventions, mode of delivery, outcome measurements, and the role of study participants. But the strict requirements of ethics committees were developed for a purpose – to protect participants from harm and help ensure the rigour and transparency of studies. We propose some guiding principles to help square this circle. First, ethics committees should acknowledge and celebrate the diversity of research approaches, both formally and informally ; without active support, their members may not understand or value participatory designs. Second, ground rules should be established for co-design applications and communicated to committee members and stakeholders. Third, the benefits of power-sharing should be recognised and credit given to measures likely to support this important goal, especially in research with vulnerable communities. Co-design is considered best practice, for example, in research involving indigenous peoples in New Zealand, Australia and Canada. (shrink)

There are many commonalities between the framework of roleplaying games such as Dungeons & Dragons and the way in which we design classes and assignments. The professor (the dungeon master) selects a number of readings with some end goal in mind (the campaign). Along the way the students are expected to be active participants (roleplay) and the professor designs progressively harder assignments (quests) in order to test the students’ abilities and to promote learning and growth (leveling up). This structural (...) analogy prompted me to investigate how such a framework could be implemented more explicitly in a class, and in this chapter I describe how I did so. (shrink)

It is well-established that the experience of nature produces an array of positive benefits to mental well-being. Much less is known about the specific attributes of green space which produce these effects. In the absence of translational research that links theory with application, it is challenging to design urban green space for its greatest restorative potential. This translational research provides a method for identifying which specific physical attributes of an environmental setting are most likely to influence preference and restoration (...) responses. Attribute identification was based on a triangulation process invoking environmental psychology and aesthetics theories, principles of design founded in mathematics and aesthetics, and empirical research on the role of specific physical attributes of the environment in preference or restoration responses. From this integration emerged a list of physical attributes defining aspects of spatial structure and environmental content found to be most relevant to the perceptions involved with preference and restoration. The physical attribute list offers a starting point for deciphering which scene stimuli dominate or collaborate in preference and restoration responses. To support this, functional definitions and metrics—efficient methods for attribute quantification are presented. Use of these research products and the process for defining place-based metrics can provide (a) greater control in the selection and interpretation of the scenes/images used in tests of preference and restoration and (b) an expanded evidence base for well-being designers of the built environment.

This essay proposes a design perspective on argumentation, intended as complementary to empirical and critical scholarship. In any substantive domain, design can provide insights that differ from those provided by scientific or humanistic perspectives. For argumentation, the key advantage of a design perspective is the recognition that humanity’s natural capacity for reason and reasonableness can be extended through inventions that improve on unaided human intellect. Historically, these inventions have fallen into three broad classes: logical systems, scientific methods, (...) and disputation frameworks. Behind each such invention is a specifiable “design hypothesis”: an idea about how to decrease error or how to increase the quality of outcomes from reasoning. As problems in contemporary argumentation practice become more complex, design thinking rises in relevance and importance. A design research agenda in argumentation would focus on theorizing design innovations and on evaluating design hypotheses. (shrink)
