This pilot study explores the possibility of cognitive training software Neurotracker (NT), to have potential beneficial effects for Traumatic Brain Injury patients with Sensory Processing Disorder. Five subjects with TBI and SPD trained for 5 weeks/21 sessions with Neurotracker. Pre-post training cognitive tests (WAIS TMTA, TMTB, LNS) and surveys were conducted to measure possible cognitive differences with no statistical significant results. However, significant improvement in Neurotracker scores were found. =2.73, SD = 0.55) and positive changes associated with attention attention span, divided attention, (multiple) object tracking and motion sickness.

Anticipatory force planning during grasping is based on visual cues about the object’s physical properties and sensorimotor memories of previous actions with grasped objects. Vision can be used to estimate object mass based on the object size to identify and recall sensorimotor memories of previously manipulated objects. It is not known whether subjects can use density cues to identify the object’s center of mass (CM) and create compensatory moments in an anticipatory fashion during initial object lifts to prevent tilt. We asked subjects (n=8) to estimate CM location of visually symmetric objects of uniform densities (plastic or brass, symmetric CM) and non-uniform densities (mixture of plastic and brass, asymmetric CM). We then asked whether subjects can use density cues to scale fingertip forces when lifting the visually symmetric objects of uniform and non-uniform densities. Subjects were able to accurately estimate an object’s center of mass based on visual density cues. When the mass distribution was uniform, subjects could scale their fingertip forces in an anticipatory fashion based on the estimation. However, despite their ability to explicitly estimate CM location when object density was non-uniform, subjects were unable to scale their fingertip forces to create a compensatory moment and prevent tilt on initial lifts. Hefting object parts in the hand before the experiment did not affect this ability. This suggests a dichotomy between the ability to accurately identify the object’s CM location for objects with non-uniform density cues and the ability to utilize this information to correctly scale their fingertip forces. These results are discussed in the context of possible neural mechanisms underlying sensorimotor integration linking visual cues and anticipatory control of grasping.

This article focuses on the role of the artistic process in connecting to the natural environment. In my research I have explored what participants experience and learn when they engage in different types of arts-based environmental education (AEE) practices that I have facilitated. The premise of AEE is that efforts to learn about our (natural) environment can effectively take their starting point in an artistic activity, usually conducted in groups. I found that, on the whole, two major orientations can be distinguished. One starts from the point of aesthetic sensibility: the tuning in with the senses, or with ‘a new organ of perception’ (Goethe), in order to perceive ‘the more than human’ with fresh new eyes. This tradition can be traced back (but is by no means limited) to the Romantic Movement. Art in this context may help to amplify the receptivity of the senses and strengthen a sense of connectedness to the natural world. The other major orientation in seeking bridges between nature and art builds on a view of artistic process as leading to unexpected outcomes and ‘emergent properties’. The fundamentally singular experience of making a work of art may evoke an aesthetic object that becomes a ‘self-sufficient, spiritually breathing subject’ (Kandinsky). The artwork can be spontaneously generative and multilayered with meanings, some of which may even be ambiguous and paradoxical. But perhaps more importantly: it can catch the participant of an AEE activity by surprise, overwhelm him or her as ‘coming from behind one’s back’. The element of improvisation, of taking in the new and unanticipated and accommodating for it, is the core quality here. These two orientations, when practiced as part of AEE, have implications on how we relate to nature through art. In the closing of this article I address the question of whether it is possible to bridge the dualism between the two orientations.

Different inputs from a multisensory object or event are often integrated into a coherent and unitary percept, despite differences in sensory formats, neural pathways, and processing times of the involved modalities. Presumably, multisensory integration occurs if the cross-modal inputs are presented within a certain window of temporal integration where inputs are perceived as being simultaneous. Here, we examine the role of ongoing neuronal alpha (i.e. 10-Hz) oscillations in multimodal synchrony perception. While EEG was measured, participants performed a simultaneity judgement task with visual stimuli preceding auditory ones. At stimulus onset asynchronies (SOA's) of 160–200 ms, simultaneity judgements were around 50%. For trials with these SOA's, occipital alpha power was smaller preceding correct judgements, and the individual alpha frequency was correlated with the size of the temporal window of integration. In addition, simultaneity judgements were modulated as a function of oscillatory phase at 12.5 Hz, but the latter effect was only marginally significant. These results support the notion that oscillatory neuronal activity in the alpha frequency range, which has been taken to shape perceptual cycles, is instrumental in multisensory perception.

This article seeks to contribute to the literature on circular business model innovation in fashion retail. Our research question is which ‘model’—or combination of models—would be ideal as a business case crafting multiple value creation in small fashion retail. We focus on a qualitative, single in-depth case study—pop-up store KLEER—that we operated for a duration of three months in the Autumn of 2020. The shop served as a ‘testlab’ for action research to experiment with different business models around buying, swapping, and borrowing second-hand clothing. Adopting the Business Model Template (BMT) as a conceptual lens, we undertook a sensory ethnography which led to disclose three key strategies for circular business model innovation in fashion retail: Fashion-as-a-Service (F-a-a-S) instead of Product-as-a-Service (P-a-a-S) (1), Place-based value proposition (2) and Community as co-creator (3). Drawing on these findings, we reflect on ethnography in the context of a real pop-up store as methodological approach for business model experimentation. As a practical implication, we propose a tailor-made BMT for sustainable SME fashion retailers. Poldner K, Overdiek A, Evangelista A.

The creation of artifacts is one of the factors that make us human. Artifacts contribute to our continual adaptation to the world by permitting better knowledge and control of it. The focus of this chapter is on the role of one specific kind of artifact: sensors. In contrast to our immediate perception of the world from our senses, sensors provide large amount of reliable measurements of the physical world that enhance human cognitive capacities in overcoming our perceptual limitations. However, “raw” sensor data require interpretation that relies on different types of expertise and knowledge to provide relevant meaning for human (adaptive) purposes. We suggest that a cognitive approach to understanding the differences between the different types of knowledge provided by current sensors as artifacts and the human senses is of interest. This approach questions the conception of human cognition as an analytic system of processing information from the world rather than as one which interprets and gives meanings to the world. We posit that understanding the differences between human and artificial sensors can shape a new era of technological advancement that is uniquely collaborative insofar as it would rely on the partnership of scientists working in the Humanities and in the Natural Sciences. In this article we provide some data from cognitive research that outline the beginnings of a pluridisciplinary endeavor to conceive sensors which integrate performances of artifacts and the diversity and richness of human cognition, with the goal of transforming so-called “intelligent” devices into cognitive sensors.

Understanding taste is key for optimizing the palatability of seaweeds and other non-animal-based foods rich in protein. The lingual papillae in the mouth hold taste buds with taste receptors for the five gustatory taste qualities. Each taste bud contains three distinct cell types, of which Type II cells carry various G protein-coupled receptors that can detect sweet, bitter, or umami tastants, while type III cells detect sour, and likely salty stimuli. Upon ligand binding, receptor-linked intracellular heterotrimeric G proteins initiate a cascade of downstream events which activate the afferent nerve fibers for taste perception in the brain. The taste of amino acids depends on the hydrophobicity, size, charge, isoelectric point, chirality of the alpha carbon, and the functional groups on their side chains. The principal umami ingredient monosodium l-glutamate, broadly known as MSG, loses umami taste upon acetylation, esterification, or methylation, but is able to form flat configurations that bind well to the umami taste receptor. Ribonucleotides such as guanosine monophosphate and inosine monophosphate strongly enhance umami taste when l-glutamate is present. Ribonucleotides bind to the outer section of the venus flytrap domain of the receptor dimer and stabilize the closed conformation. Concentrations of glutamate, aspartate, arginate, and other compounds in food products may enhance saltiness and overall flavor. Umami ingredients may help to reduce the consumption of salts and fats in the general population and increase food consumption in the elderly.

Europeans are living longer than ever in history, because of the economic growth and advances in hygiene and health care. Today, average life expectancy is over 80, and by 2020 around 25% of the population will be over 65. The increasing group of older people poses great challenges in terms of creating suitable living environments and appropriate housing facilities. The physical indoor environment plays an important role in creating fitting, comfortable and healthy domestic spaces. Our senses are the primary interface with the built environment. With biological ageing, a number of sensory changes occur as a result of the intrinsic ageing process in sensory organs and their association with the nervous system. These changes can in turn change the way we perceive the environment around us. It is important to understand these changes when designing for older occupants, for instance, care homes, hospitals and private homes, as well as office spaces given the developments in the domain of staying active at work until older age.
