A Multi-Sensory Approach to Teaching Spelling to Learning Disabled Children

Problem Learning disabled children are receiving increasing attention, for despite an intelligence quotient within the normal range, they are not achieving in school as well as their peers. The reasons offered for this phenomenon seem to relate to perceptual problems. Specific learning disabilities occur in reading, arithmetic, spelling, handwriting and other motor coordination areas. This study investigates the effect of a multi-sensory method of teaching spelling to learning disabled children using sandpaper letters to utilize the tactile and kinesthetic sensory modalities. Method Unfamiliar spelling words were taught to 40 learning disabled children, 38 boys and 2 girls. The children were matched by age. One group was taught traditionally and the other group was taught using sandpaper letters. The pretest and post test were scored and an analysis of covariance and a regression analysis of the independent variables was performed on the data. An analysis was also made on the types of errors the children made. Results An analysis of the data showed that the experimental group did not do any better than the control group nor were particular types of errors helped significantly by the experimental method. Conclusions Although the experimental group did not do significantly better than the control group, it would be premature to conclude that adding a tactile, kinesthetic element to teaching spelling is worthless. Many factors could have had an influence on the experiment. Further studies are needed to make a judgment of the applicability of this remedial method

Seeing Numbers

In 1890 William James listed several “elementary mental categories” that he postulated as having a natural origin. Among them, alongside the ideas of time and space, he also listed the idea of number. A symptomatic feature of Informatics as well as Cognitive Science today is the tendency not to talk so much about ideas as about their representations, either in the computer or in the brain. Taking up somewhat different perspective I will discuss the way natural numbers, viewed as counts of real or imagined objects, may be experienced phenomenally. I put forth even some speculative ideas about mental number processing by numerical savants

Visualizing Individual Perceptual Differences Using Intuitive Word-Based Input

Numerous studies have investigated the fundamental dimensions of human tactile perceptual space using a wide range of materials. Participants generally touch materials and quantitatively evaluate variations in tactile sensations for pairs of adjectives pertaining to the material properties, such as smooth—rough and soft—hard. Thus, observers evaluate their perceptual experiences one by one in terms of adjective pairs. We previously proposed an alternative method of qualitative evaluation of tactile sensations. Our system can automatically estimate ratings of fundamental tactile properties from single sound-symbolic words. We were able to construct a word-based perceptual space by collecting words that express tactile sensations and applying them to the system. However, to explore individual differences in perceptual spaces, different databases for converting words into ratings of adjective pairs are required for each individual. To address this, in the present study we created an application that can automatically generate an individualized perceptual space by moving only a few words in the initial word-based perceptual space. In addition, we evaluated the efficacy of the application by comparing the tactile perceptual space before and after use

Human Neurological Development: Past, Present and Future

Neurological development is considered as the major human potential. Vision, vestibular function, intelligence, and nutrition are discussed as well as the treatment of neurological disfunctions, coma, and convulsive seizures

Spatial representation and visual impairement - Developmental trends and new technological tools for assessment and rehabilitation

It is well known that perception is mediated by the five sensory modalities (sight, hearing, touch, smell and taste), which allows us to explore the world and build a coherent spatio-temporal representation of the surrounding environment. Typically, our brain collects and integrates coherent information from all the senses to build a reliable spatial representation of the world. In this sense, perception emerges from the individual activity of distinct sensory modalities, operating as separate modules, but rather from multisensory integration processes. The interaction occurs whenever inputs from the senses are coherent in time and space (Eimer, 2004). Therefore, spatial perception emerges from the contribution of unisensory and multisensory information, with a predominant role of visual information for space processing during the first years of life. Despite a growing body of research indicates that visual experience is essential to develop spatial abilities, to date very little is known about the mechanisms underpinning spatial development when the visual input is impoverished (low vision) or missing (blindness). The thesis's main aim is to increase knowledge about the impact of visual deprivation on spatial development and consolidation and to evaluate the effects of novel technological systems to quantitatively improve perceptual and cognitive spatial abilities in case of visual impairments. Chapter 1 summarizes the main research findings related to the role of vision and multisensory experience on spatial development. Overall, such findings indicate that visual experience facilitates the acquisition of allocentric spatial capabilities, namely perceiving space according to a perspective different from our body. Therefore, it might be stated that the sense of sight allows a more comprehensive representation of spatial information since it is based on environmental landmarks that are independent of body perspective. Chapter 2 presents original studies carried out by me as a Ph.D. student to investigate the developmental mechanisms underpinning spatial development and compare the spatial performance of individuals with affected and typical visual experience, respectively visually impaired and sighted. Overall, these studies suggest that vision facilitates the spatial representation of the environment by conveying the most reliable spatial reference, i.e., allocentric coordinates. However, when visual feedback is permanently or temporarily absent, as in the case of congenital blindness or blindfolded individuals, respectively, compensatory mechanisms might support the refinement of haptic and auditory spatial coding abilities. The studies presented in this chapter will validate novel experimental paradigms to assess the role of haptic and auditory experience on spatial representation based on external (i.e., allocentric) frames of reference. Chapter 3 describes the validation process of new technological systems based on unisensory and multisensory stimulation, designed to rehabilitate spatial capabilities in case of visual impairment. Overall, the technological validation of new devices will provide the opportunity to develop an interactive platform to rehabilitate spatial impairments following visual deprivation. Finally, Chapter 4 summarizes the findings reported in the previous Chapters, focusing the attention on the consequences of visual impairment on the developmental of unisensory and multisensory spatial experience in visually impaired children and adults compared to sighted peers. It also wants to highlight the potential role of novel experimental tools to validate the use to assess spatial competencies in response to unisensory and multisensory events and train residual sensory modalities under a multisensory rehabilitation

Translations of Blind Perception in the Films Monika (2012) and Antoine (2008)

Against the backdrop of these works (Mitchell/Snyder and others), we propose an analysis of films with and about blind or visually disabled individuals that aims at exploring different modes of world perception. In our view, such an examination should not only discuss the question of “giving voice” and visibility to those who were formerly only represented in or by the media, or the fact that films belonging to what might be considered a “new disability documentary cinema” are dedicated to the experience of disability from the point of view of those who deal with it. Rather, we examine films that do not restrict their field of vision to institutional context as cultural productions. These films allow the viewer to get to know different practices of seeing in the daily life of both blind or visually disabled and sighted people. In approaching these productions, we are interested in focusing on how the audio-visual regimes produce and structure our visual experience, translate it into a filmic grammar and thus not only create filmic patterns of blind perception but, at the same time, the cinematographic aesthetic of a so-called normal sightedness

An Animal Among Animals

The discourse of Animal Studies has been gaining momentum as a scholarly discipline, advanced in remarkably diverse ways by theorists such as Jakob Von Uexkll, Gilles Deleuze, Donna Haraway, Michel Serres, and Giorgio Agamben. Drawing on these theorists, my research on animality seeks to name what the animal represents, as well as situate the human as an animal, and address questions of ecology and non-anthropocentric relational subjectivity. I will also look at several artists who have advanced the cultural identity of animals through their work including LinLee-Chen, Jochen Lempert, and Pudlo Pudlat. This paper proposes to reject the notion of humans as separate from nature and emphasizes the exploration of unrecognized forms of knowledge acquired from the parallel lifeworlds of animals. I will also describe my method of practice-based research through visual art as a means to approach the abstract and often inaccessible knowledge of an animals experience without favoring the anthropomorphic constraints of language. My visual research employs storytelling and metaphors through painting, drawing on personal narratives or dreams as a medium to engage the multiplicity of worlds and reveal meaning without imparting propositional claims. I will walk the reader through the accompanying thesis exhibition, describing a series of paintings that focus on rendering animal experiences that are oftentimes disregarded or invisible to our human affordances. A large-scale installation will facilitate a space that situates the viewer in relation to nonhuman animals inhabiting parallel environments. Paintings focused on rendering the physicality and vantage points of nonhuman animals, along with non-pictorial elements, are used to disengage anthropomorphic assumptions and situate human animality in a symbiogenetic relationship with other animals
