Auditory Focus Auditory Focus Sound environment and participation for pupils with visual impairment Sara Backström Lindeberg Department of Special Education Degree Project (30 credits) Special Education Master’s Programme in Special Education with Specialization in Visual Impairment Pedagogy (120 credits) Spring semester 2014 Supervisor: Kerstin Fellenius English title: Auditory Focus Sound environment and participation for pupils with visual impairment Auditory Focus Sound environment and participation for pupils with visual impairment Sara Backström Lindeberg Abstract This study investigates auditory accessibility and participation for pupils with blindness in everyday school situations. What opportunities do the pupils have to use their hearing to distinguish and gain access to social and educational processes in different sound environments? Auditory observations by researchers and pupils have been made in various school environments at five Swedish schools. At the same time, qualitative interviews have been conducted with five pupils aged 8–18 years. A theoretical model has been generated on the basis of grounded theory. This model describes auditory identification processes and cognitive processes for access to social and educational contexts in activities, which is the study’s main concern. The results of the study indicate that the pupils constantly use sound to gain access to both social and educational processes, and that sound is often their most important and only source of information. The study also shows that the sound environment is decisive in terms of the pupils’ opportunities to participate. In environments meant for social interaction (dining halls, after-school recreation centres, corridors) it is often impossible to distinguish friends’ voices and the context of activities because of the high sound levels, large number of people and large number of concurrent activities. This makes the sound information relatively anonymous, which in turn makes social interaction more difficult. An environment that is too quiet, without verbal communication, also becomes anonymous. However, the pupils’ chances of identifying voices, processes and contexts are very good in functional sound environments. Small, subtle details are often an important aspect of the auditory information. Cognitive processes, such as experience and inference, are important for piecing together the auditory information in a constantly changing sound environment. The results also point to situations requiring double auditory focus in the classroom that become difficult for pupils to manage. Results also shows that verbal information cannot be equated with written information in teaching situations when it comes to exposure time, overview, repetition and working memory requirements. The implications for organisational structure, educational working practices and the design of premises that can increase the pupils’ opportunities to participate are discussed in the study. Keywords Visual impairment, blindness, auditory accessibility, sound environment, participation, social interaction, school. Preface and Acknowledgements Outside the window spring is in full bloom. Now, as I come to the end and turn off my computer, the lush scent of cherry blossom, the birds’ ethereal twittering and the warm spring breezes await me. Completing this paper has been a long, laborious process, but also an extremely exciting and educational journey along unfamiliar, winding roads. It is with certain sadness that I bring this effort to a close. I am grateful to the many people who have provided me with assistance along the way. First and foremost, I want to express my deepest and warmest gratitude to the pupils Molly, Jacob, Hilda, Kim and Daniel, who so generously shared their wise and important thoughts, for allowing me to join you in school. You are the very foundation of this paper and without you it would not have amounted to anything. I am also grateful to their teachers for welcoming me so warmly to participate. A huge thank you also goes to Kerstin for your wise and humble supervision, and for putting up with my obstinacy. Your knowledge and experience has taught me so much. Thanks also my employer, the Swedish National Agency for Special Needs Education and Schools, which has made it possible for me to undertake this study partly within the scope of my work. Another person who has been incredibly important throughout this work is my reader Sara. You have done a huge amount of work and been a great support. Thank you! Huge thanks also go to my colleagues Tina, Annica and Tove, who have been involved in the study as keen-eyed observers. Special thanks to Tove for your read- throughs and your commitment. You don’t realise how valuable you are. I hope we go on to have many more interesting conversations. I am also grateful to my colleague Kia; thank you for your unfailingly exquisite language suggestions. Finally, I would like to thank my dear family – my children Linus and Matilda-Lo – for patiently putting up with an occasionally somewhat absent mother, and last, but not least, my husband and soulmate Greger. I am thankful for your eternal commitment, your loving support and your knowledge!

  • Cognitive Abilities in Human Echolocation
    Umeå University Department of Psychology Master Thesis VT2010 Cognitive Abilities in Human Echolocation Oskar Andersson Supervisor: Bo Schenkman Steven Nordin Abstract The human ability to echolocate differs between individuals. Blind perform significantly better then sighted. There is very limited research on psychological factors underlying this ability. This study is based on earlier research by Schenkman and Nilsson (2010). The research questions in the present study were whether blind individuals perform better then sighted on general cognitive tasks, if people who perform well on echolocation tasks, also perform well on general cognitive tasks, and is there a correlation between performance on echolocation tasks and general cognitive tasks? Participants were 8 blind (5 female and 3 men) and 4 sighted (3 female and 1 male). Range of age was 36 – 65 years. Cognitive test used were Digit Span, California Verbal Learning Test and an auditiv reaction time test. The blind performed significantly better than the sighted on learning over trials. There was significant difference in focused attention, working memory and learning over trials between individuals who performed well on echolocation tasks and the rest of the sample. There was a positive correlation between learning over trials and individuals ability to echolocate. The conclusion of this report is that blind individuals perform better on learning over trials and that people who perform well on echolocation tasks are superior in the cognitive abilities focused attention, working memory and learning over trials. Cognitive Abilities in Human Echolocation Oskar Andersson Echolocation is often associated with mammals like bats, dolphins and whales. These animals all hold the ability to echolocate with great precision, and echolocation is used for orientation and hunting.

The rapid development the last decades have made both work and education much more accessible. Despite this, moving about independently is still a major challenge, one that at worst can lead to isolation and a decreased quality of life. To aid in the above task, devices exist to help avoid obstacles (notably the white cane), and navigation aids such as accessible GPS devices. The white cane is the quintessential aid and is much appreciated, but solutions trying to convey distance and direction to obstacles further away have not made a big impact among the visually impaired. One fundamental challenge is how to present such information non-visually.

  • Visuospatial Assistive Device Art: Expanding Human Echolocation Ability
    Visuospatial Assistive Device Art: Expanding Human Echolocation Ability March ２０18 Aisen Carolina Chacin 1 Visuospatial Assistive Device Art: Expanding Human Echolocation Ability School of Integrative and Global Majors Ph.D. Program in Empowerment Informatics University of Tsukuba March２０18 Aisen Carolina Chacin 2 Abstract: This study investigates human echolocation through sensory substitution devices for the augmentation of visuospatial skills, thus replacing vision through acoustic and haptic interfaces. These concepts are tested through two case studies; Echolocation Headphones and IrukaTact. The Echolocation Headphones are a pair of goggles that disable the participant's vision. They emit a focused sound beam which activates the space with directional acoustic reflection. The directional properties of this parametric sound provide the participant a focal echo. This directionality is similar to the focal point of vision, giving the participant the ability to selectively gain an audible imprint of their environment. This case 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. The second case study is the IrukaTact haptic module, a wearable device for underwater tactile stimulation of the fingertips with a jet-stream of varying pressure. This haptic module utilizes an impeller pump which suctions surrounding water and propels it onto the volar pads of the finger, providing a hybrid feel of vibration and pressure stimulation. IrukaTact has an echo-haptic utility when it is paired with a sonar sensor and linearly transposing its distance data into tactile pressure feedback.

  • From Visual to Aural Space: a Change of Paradigm?*
    FROM VISUAL TO AURAL SPACE: A CHANGE OF PARADIGM?* FREDERICO ALBERTO B. MACÊDO Resumo: neste artigo discuto como a influência de Visualism levou à concepção equivocada segundo a qual o espaço é principalmente um domínio visual. Diferentes abordagens para a percepção mostram evidências de que todos os sentidos estão envolvidos na percepção do espaço. Pesquisas recentes sobre percepção auditiva e localização humana também mostram evidências de que o sistema au- ditivo tem a capacidade de detectar e processar as infor- mações espaciais em um nível insuspeito por pesquisadores que consideravam a audição como uma sensação com pou- cas informações sobre as relações espaciaia. Na conclusão, sugerem que a mudança de visual para o espaço auditivo pode representar mais do que simplesmente uma mudança de variáveis​​, mas um sintoma de uma mudança cultural mais profunda, uma consideração mais equilibrada dos sentidos como um todo, refletida na antiga idéia de sensus communis.

    Human Echolocation By Santani Teng A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Psychology in the Graduate Division of the University of California, Berkeley Committee in charge: Professor David Whitney, Chair Professor Frederic Theunissen Professor Michael Silver Fall 2013 Abstract Human Echolocation by Santani Teng Doctor of Philosophy in Psychology University of California, Berkeley Professor David Whitney, Chair The use of active natural echolocation as a mobility aid for blind humans has received increased scientific and popular attention in recent years (Engber, 2006; Kreiser, 2006; NPR, 2011), in part due to a focus on several blind individuals who have developed remarkable expertise. However, perhaps surprisingly, the history of empirical human echolocation research is not much younger than the era of echolocation research (cf. Griffin, 1958). Nevertheless, compared to its bat and cetacean counterparts (Thomas et al., 2004), the field today remains in a state of comparative infancy. Until quite recently, nearly the entire body of human echolocation research has been behavioral in nature, with little insight into perceptual and neural mechanisms. Thus, the goal of this manuscript is to broadly integrate research findings in human echolocation across time, levels of analysis, and methodology. We will define human echolocation as it has been operationalized in research and practice, review behavioral goals served by echolocation, and identify putative auditory cues and neural mechanisms underpinning human echolocation. We examine some individual differences in echolocation performance, particularly involving blind compared to sighted persons. We present two studies in detail, addressing the spatial acuity of echolocation skills in sighted volunteers and blind experts.

Human echolocation is a technique useable by any human, but most notably by the blind and visually impaired. The technique is similar to echolocation used by bats and dolphins, which use it to navigate in total darkness and under water. There are two different forms of echolocation: active and passive. Actively producing sounds in order to receive localization information from the reflected echoes, is known as active echolocation. Passive echolocation is the interpretation of reflected echoes from sounds produced by your surroundings. Most blind and visually impaired already use some of the aspects of passive echolocation unconsciously. Active echolocation however, needs to be taught, just like the use of a cane. A trained echolocator can use echolocation to navigate his surroundings far beyond the reach of his cane and identify objects and people as if sighted. The use of this technique requires sensitivity and rapid analysis of the properties of both self- generated sounds and its echoes, as well as the sounds and echoes produced by the surroundings.

  • Auditory-Based Rehabilitation in the Visually Deprived Brain of Optic
    Auditory-based rehabilitation in the visually deprived brain of optic neuropathy patients Carina Sabourin Abstract Due to the extent humans rely on vision, sight restoration approaches are the predominant treatment option con- sidered for optic neuropathy patients with vision loss. This trend is refected in the wealth of research on sight restoration procedures. Patients with irreversible vision loss are left with limited treatment options due to the lack of research on alternative therapeutics and the prevalence of misdiagnosis (Jay 2016; Weerasinghe & Lueck 2016). Compensatory plasticity holds that auditory input can colonize the available cortical space in the visually deprived brain. The resulting enhancements in auditory cognition can be capitalized on by auditory-based rehabilitative tools. Sensory substitution devices have allowed visually deprived individuals to hear ‘colours’ and ‘shapes’, per- ceive their surroundings (Collignon, Champoux, Voss, & Lepore, 2011; Striem-Amit, Guendelman, & Amedi, 2012) and even read ‘written’ letters (Striem-Amit, Cohen, Dehaene, & Amedi, 2012) using soundscapes. VD echolocators navigate through daily obstacles using tongue clicks (Arnott, Thaler, Milne, Kish, & Goodale, 2013; A. J. Kolarik, Cirstea, Pardhan, & Moore, 2014; A. J. Kolarik, Scarfe, Moore, & Pardhan, 2017; Papadopoulos, Edwards, Row- an, & Allen, 2011; Teng, Puri, & Whitney, 2012; Teng & Whitney, 2011; Thaler, Arnott, & Goodale, 2011). Many higher order visual regions retain their functional specialization and adapt to auditory input from soundscapes or tongue clicks (O. Collignon, Lassonde, Lepore, Bastien, & Veraart, 2006; A. J. Kolarik et al. 2014; Striem-Amit & Amedi, 2014; Striem-Amit, Cohen, et al. 2012; Thaler et al. 2011). Due to the interaction between critical periods and plasticity, the therapeutic value of rehabilitative tools can vary with age of onset.
