Filter by:My Space aims to identify the ontogenesis of spatial representation through cross-sectional and longitudinal studies in infants, children, and adolescents with typical and atypical development (visual impairments). The results will serve for the design and development of a novel multisensory device for sensorimotor rehabilitation in blind children from the early stages of life.
Purpose: This project aimed to examine the effects of laughter yoga, which is accepted as an international nursing initiative, on loneliness, anger and salivary cortisol levels in visually impaired individuals. When the national and international literature was examined, no project was found that measured the results of laughter yoga as an intervention for visually impaired individuals. For this reason, planning an original project in this field aims to contribute to the literature. Thanks to the evidence obtained, laughter yoga, an innovative approach, can be disseminated in institutions and organizations serving visually impaired individuals as an evidence-based practice that can improve the social skills of individuals. Scope and Target Audience: The project will be carried out with visually impaired individuals receiving services in the Disabled Persons Department within the Atatürk Provincial Public Library located in Konak district of Izmir. In this section, services are provided to 250 members who actively use the library and to visually impaired people from all over Turkey. Method and Expected Result: The project was planned in a randomized controlled, pre-test post-test, single-blind follow-up consultancy design. With this initiative, a social rehabilitation environment will be provided for visually impaired individuals by taking an approach based on respect, understanding and awareness. Laughter yoga is expected to reduce the level of anger and loneliness in visually impaired individuals. At the same time, laughter yoga is expected to reduce cortisol levels, which are known to increase when faced with stress factors, and increase serotonin, which is associated with happiness and vitality, and endorphine, known as the body's natural painkiller. With laughter yoga sessions, a social environment will be created where visually impaired individuals will have an active and independent experience. Thanks to the expected evidence, laughter yoga can be popularized both in visually impaired individuals and in individuals with other disabilities. Within the scope of protecting and improving health, laughter yoga can be planned to be carried out as a routine nursing practice in disabled centers. Thus, by creating an environment where visually impaired individuals and nurses come together, a more accessible health service will be provided to individuals with special needs.
The purpose of this study is to evaluate reading performance in the visual periphery by simulating central vision loss using a computer-controlled gaze-contingent display with an eye tracker. Participants will read a page of text at a comfortable rate. Several manipulations hypothesized to improve reading will be tested, such as an inverted-text "spotlight" of a single word that follows the participant's gaze.
The investigators will re-investigate 150 children studied extensively in the past. 100 of these children were born to mothers prescribed methadone during their pregnancy because of opiate dependency, and 50 were comparison children who were not exposed to drugs. These children were investigated when they were newborn babies, and again when they were six months old, and a quarter of the drug-exposed babies had problems with their eyesight, whilst very few of the comparison children has eyesight problems. The investigators would like to see whether the eyesight problems are still present in the children now that they are older. Because they are older, more detailed testing can be undertaken which will help to understand how drug exposure in the womb may have affected their eyesight. The investigators will recruit new, comparison children to the study to match the number of comparison children with the number of drug-exposed children. The findings will be relevant and important when advising mothers on drug use - both prescribed and illicit - when they are pregnant.
