Article
Introduction: A comprehensive assessment of visual functioning at an early age is important not only for identifying and defining visual impairment but also for planning personalized rehabilitation programs based on the visual diagnosis. Since existing tools to evaluate visual functioning present some important limitations (e.g., they are based on...
Article
Full-text available
It is well known that primary school children may face difficulties in acquiring mathematical competence, possibly because teaching is generally based on formal lessons with little opportunity to exploit more multisensory-based activities within the classroom. To overcome such difficulties, we report here the exemplary design of a novel multisensor...
Article
Vision and touch play a critical role in spatial development, facilitating the acquisition of allocentric and egocentric frames of reference, respectively. Previous works have shown that children’s ability to adopt an allocentric frame of reference might be impaired by the absence of visual experience during growth. In the current work, we investig...
Article
Full-text available
Associations between sensory features of different natures are defined as crossmodal correspondences. In the context of size perception, low pitch sound frequencies are often associated with larger objects and high pitch with smaller objects. Here we investigate such crossmodal correspondences in sighted and visually-impaired children. In Experimen...
Article
Background Parent-child interaction is essential to promote adaptive emotional, cognitive, and social development. The majority of previous research on parent-child interaction is largely dependent on face-to-face exchanges that require the interactive partners to visually recognize reciprocal communicative bids. Therefore, previous findings in the...
Article
Full-text available
Self-motion perception used for locomotion and navigation requires the integration of visual, vestibular, and proprioceptive input. In the absence of vision, postural stability and locomotor tasks become more difficult. Previous research has suggested that in visually deprived children, postural stability and levels of physical activity are overall...
Article
Full-text available
Research has shown that the ability to integrate complementary sensory inputs into a unique and coherent percept based on spatiotemporal coincidence can improve perceptual precision, namely multisensory integration. Despite the extensive research on multisensory integration, very little is known about the principal mechanisms responsible for the sp...
Article
Full-text available
Sensory cues enable navigation through space, as they inform us about movement properties, such as the amount of travelled distance and the heading direction. In this study, we focused on the ability to spatially update one's position when only proprioceptive and vestibular information is available. We aimed to investigate the effect of yaw rotatio...
Article
Full-text available
The acquisition of spatial cognition is essential for both everyday functioning (e.g., navigation) and more specific goals (e.g., mathematics), therefore being able to assess and monitor spatial cognition from the first years of life would be essential to predict developmental outcomes and timely intervene whenever spatial development is compromise...
Article
Full-text available
Congenital visual impairment may have a negative impact on spatial abilities and result in severe delays in perceptual, social, motor, and cognitive skills across life span. Despite several evidences have highlighted the need for an early introduction of re-habilitation interventions, such interventions are rarely adapted to children’s visual capab...
Conference Paper
Full-text available
The aim of the present work is to introduce a novel wearable device suitable to be used to investigate perception in interactive tasks, on individuals with and without sensory disabilities. The system is composed by small units embedded with sensors and actuators that allows emitting different kind of stimuli (light, haptic, sound) and to record th...
Article
Full-text available
Several works have demonstrated that visual experience plays a critical role in the development of allocentric spatial coding. Indeed, while children with a typical development start to code space by relying on allocentric landmarks from the first year of life, blind children remain anchored to an egocentric perspective until late adolescence. None...
Article
Recent studies have demonstrated that audition used to complement or substitute visual feedback is effective in conveying spatial information, e.g., sighted individuals can understand the curvature of a shape when solely auditory input is provided. Recently we also demonstrated that, in the absence of vision, auditory feedback of body movements can...
Article
Full-text available
Several reports indicate that spatial perception in blind individuals can be impaired as the lack of visual experience severely affects the development of multisensory spatial correspondences. Despite the growing interest in the development of technological devices to support blind people in their daily lives, very few studies have assessed the ben...
Article
Full-text available
Developmental studies have shown that children can associate visual size with non-visual and apparently unrelated stimuli, such as pure tone frequencies. Most research to date has focused on audiovisual size associations by showing that children can associate low pure tone frequencies with large objects, and high pure tone frequencies with small ob...
Article
Full-text available
Blind individuals are particularly dependent on their hearing for defining space. It has been found that both children and adults with visual impairments can struggle with complex spatial tasks that require a metric representation of space. Nonetheless the variability of methods employed to assess spatial abilities in absence of vision is wide, esp...
Data
Raw data presented by tasks. The file contains the raw data for each task performed (auditory localization, auditory bisection, auditory distance, auditory reaching, proprioceptive reaching, general mobility) on sessions one and two for each participant involved in the study. (XLSX)
Article
Full-text available
Since it has been demonstrated that spatial cognition can be affected in visually impaired children, training strategies that exploit the plasticity of the human brain should be early adopted. Here we developed and tested a new training protocol based on the reinforcement of audio-motor associations and thus supporting spatial development in visual...
Article
Full-text available
In the last years, the positive impact of sensorimotor rehabilitation training on spatial abilities has been taken into account, e.g. providing evidence that combined multimodal compared to unimodal feedback improves responsiveness to spatial stimuli. To date, it still remains unclear to which extent spatial learning is influenced by training condi...
Chapter

The authors discuss user preferences related to sounds and tactile materials and present the results of a focus group...
Article
Visually impaired children and adults have difficulties in engaging in positive social interactions. This study assesses social competence in sighted and visually impaired people and to propose a novel interventional strategy in visually impaired children. We designed a task that assesses the ability to initiate and sustain an interaction with the...
Conference Paper
Full-text available
In primary school, children tend to have difficulties in discriminating angles of different degrees and categorizing them either as acute or obtuse, especially at the first stages of development (6-7 y.o.). In the context of a novel approach that intends to use other sensory modalities than visual to teach geometrical concepts, we ran a psychophysi...
Conference Paper
This paper discusses self-efficacy, curiosity, and reflectivity as cognitive and affective states that are critical to learning but are overlooked in the context of affect-aware technology for learning. This discussion sits within the opportunities offered by the weDRAW project aiming at an embodied approach to the design of technology to support e...
Article
Full-text available
Since it has been shown that spatial development can be delayed in blind children, focused sensorimotor trainings that associate auditory and motor information might be used to prevent the risk of spatial-related developmental delays or impairments from an early age. With this aim, we proposed a new technological device based on the implicit link b...
Poster
The poster presents a rehabilitation kit which aims at stimulating visually impaired children and to increase their spatial abilities. The contribution is in the reduction of the complexity of the stimulation setup, which targets a lightweight system and a reduction of the exercise time.

Article
Full-text available
The specific role of early visual deprivation on spatial hearing is still unclear, mainly due to the difficulty of comparing similar spatial skills at different ages and to the difficulty in recruiting young blind children from birth. In this study, the effects of early visual deprivation on the development of auditory spatial localization have bee...
Article
Full-text available
Blind individuals show impairments for auditory spatial skills that require complex spatial representation of the environment. We suggest that this is partially due to the egocentric frame of reference used by blind individuals. Here we investigate the possibility of reducing the mentioned auditory spatial impairments with an audio-motor training....
Article
Full-text available
Different sensory systems interact to generate a representation of space and to navigate. Vision plays a critical role in the representation of space development. During navigation, vision is integrated with auditory and mobility cues. In blind individuals, visual experience is not available and navigation therefore lacks this important sensory sig...

Article
Full-text available
Considering that cortical plasticity is maximal in the child, why are the majority of technological devices available for visually impaired users meant for adults and not for children? Moreover, despite high technological advancements in recent years, why is there still no full user acceptance of existing sensory substitution devices? The goal of t...
Article
Full-text available
Central tendency, the tendency of judgements of quantities (lengths, durations etc.) to gravitate towards their mean, is one of the most robust perceptual effects. A Bayesian account has recently suggested that central tendency reflects the integration of noisy sensory estimates with prior knowledge representations of a mean stimulus, serving to im...
Data
In these five 40 × 40 performance matrices all 40 images (1–20: Rob and 21–40: Dom) are placed along both the x and y axes. The value in each cell specifies the number of times two images were placed in the same pile pooled across 6- and 7-year-olds (A), 8- and 9-year-olds (B), 10- and 11-year-olds (C), 12- to 14-year-olds (D) and adults (E). The t...

Unfamiliar face recognition follows a particularly protracted developmental trajectory and is more likely to be atypical in children with autism than those without autism. There is a paucity of research, however, examining the ability to recognize the same face across multiple naturally varying images. Here, we investigated within-person face recog...
Article
It is not clear what role visual information plays in the development of space perception. It has previously been shown that in absence of vision, both the ability to judge orientation in the haptic modality and bisect intervals in the auditory modality are severely compromised (Gori, Sandini, Martinoli & Burr, 2010; Gori, Sandini, Martinoli & Burr...
Article
Full-text available
The consequence of blindness on auditory spatial localization has been an interesting issue of research in the last decade providing mixed results. Enhanced auditory spatial skills in individuals with visual impairment have been reported by multiple studies, while some aspects of spatial hearing seem to be impaired in the absence of vision. In this...
Conference Paper
Full-text available
The acquisition of spatial capabilities is driven by the reciprocal influence between visual perception and execution of movements [Bremner et al., 2008]. In fact we recently found that early blind people are severely impaired in both the auditory and the haptic spatial domains [Gori et al., 2012; Gori et al., 2014], suggesting that the absence of...
Conference Paper
The present paper reports on a games workshop within the ABBI EU project involving children with visual impairments as co-creators. The created games show that it is possible to create fun, rich and social co- located games with wearable technology employing very simple interactivity. Having a device that makes a sound when you move allows for th...

This study is done within the framework of a project aimed at developing a wearable device (a bracelet) intended to support sensory motor rehabilitation of children with visual impairments. We present an exploratory study of aesthetic/hedonistic preferences for sounds and touch experiences among visually impaired children. The work is done in a par...
Conference Paper
Full-text available
Experiments on humans and animals indicate that auditory localization develops through the association of sets of monaural and binaural cues and locations in space: this calibration process in guided by vision (Knudsen, 1989). The auditory system lacks a straightforward correspondence between external spatial locations and sensory receptive fields...

Early onset of blindness adversely affects psychomotor, emotional and social development [1], that mostly depend on spatial cognition. Some studies suggest that the lack of vision could potentially explain this delayed or weakened development since vision is the most accurate and robust sense to encode spatial information [2,3,4]. We recently found...

Introduction Studies of cross-modal plasticity in blind people typically show that blind subjects perform as well as, or even better than, sighted controls when tested for various auditory or tactile discrimination tasks. Differently, we report that visually impaired adults and children are impaired in those auditory and proprioceptive tasks that r...

We recently showed that congenitally blind adults have severely impaired thresholds in an auditory spatial bisection task, pointing to the importance of vision in constructing auditory spatial maps (Gori et al.2014). To test if also children show a spatial impaired performance, we compared blind and sighted children (6-16 years) on different aspec...

Background: Central tendency, the tendency of judgements of quantities (of length, duration, number, color etc.) to gravitate towards their mean value, is one of the most robust effects in perception. In the temporal domain, duration estimates of the same time intervals are shorter or longer depending on whether they are presented in the context...
