A comparison of sighted and visually impaired children's text comprehension

Research on immersive interaction design based on visual and tactile feature analysis of visually impaired children

To propose improved and innovative visual-tactile interaction design for visually impaired children, multi-modal combination approaches have been applied, such as voice interaction, touch interaction, and multi-modal systems, what's more, aided cognitive approaches help them deepen their understanding of objects, improve their cognitive level, and increase their interest.

METHODS

To improve the amount of information in the visual-haptic interface by integrating multiple sensory information, based on the cognitive patterns of visually impaired children, a questionnaire was used to design a tactile-visual UI for the main content objects of visually impaired children when using the Internet, from which difficulties and problems in the design of visual-haptic for visually impaired children were found, and design improvements were proposed based on the principles and methods of accessible design.

RESULTS

The personalized and humanized design activities enhance the confidence and improve the quality of life of the visually impaired children group and produce positive effects, improving the cognitive clarity of visually impaired children while increasing their level of understanding, imagination, learning interest and aesthetic experience.

CONCLUSION

The physical and mental characteristics and visual and tactile characteristics of visually impaired children are analyzed, and the application of UI interaction design is based on these characteristics. The essence of interaction design is outlined through experiments, and it is found that with the development of the Internet, big data and artificial intelligence, visually impaired children have many difficulties in the use of the Internet, and through the improved practice of immersive interaction design, the humanized design approach is used to enhance visually impaired children's experience of using network interfaces. Through the improved practice of immersive interaction design, we improve the way of visually impaired children using the Internet, narrow the gap between them and normal children in the interaction, and give humanistic care.

The Role of Morphological Awareness in Listening Comprehension of Chinese Blind Children: The Mediation of Vocabulary Knowledge

Background

Listening comprehension is particularly important in children without sight. Little research has focused on listening comprehension. There are strong correlations among syllables, morphemes, and orthographic representations in Chinese. For this reason, vocabulary knowledge may have a mediating role in morphological awareness and listening comprehension in blind children during the elementary school.

Methods

The study that included measures of children’s age, working memory, rapid automatized naming, phonological awareness, morphological awareness, vocabulary knowledge, and listening comprehension was administered to 142 Chinese‐speaking blind children during the early elementary level (Grades 1 to 3) and late (Grades 4 to 6). Through a mediation analysis following the bootstrapping procedures.

Results

The study shows that (1) morphological awareness predicted listening comprehension in blind children directly; (2) after children’s age, working memory, rapid automatized naming, and phonological awareness controlled, vocabulary knowledge plays a mediating role in morphological awareness and listening comprehension.

Conclusion

The findings of the present study indicate the important unique role of morphological awareness and the mediation of vocabulary knowledge in blind children’s listening comprehension during the elementary school years.

COVID-19 and Food-Related Outcomes in Children with Autism Spectrum Disorder: Disparities by Income and Food Security Status

BACKGROUND

Limited research suggests increased adverse behavioral outcomes, such as distractibility and hyperactivity, among children with autism spectrum disorder (ASD) as a result of coronavirus 2019 (COVID-19); however, little is known about how the pandemic has impacted food-related behaviors among children with ASD.

OBJECTIVE

This study characterizes the impact of the pandemic on access to preferred foods and eating behaviors among children with ASD.

METHODS

Caregiver proxies (n = 200) participated in a cross-sectional, online survey investigating the impact of COVID-19 on reported food and eating behaviors of children, ages 2-17 y. Logistic regression models were used to assess the magnitude of association of a change in the child's eating behaviors and in food availability, overall and by household income and food security status.

RESULTS

A majority of respondents reported a moderate-to-large impact on their child's eating behaviors (57%) since the onset of COVID-19, and 65% reported unavailability of their child's preferred foods. Increased risk of a moderate-to-large impact on children's eating behaviors was associated with shelter regulations compared with no regulations (OR: 2.30; 95% CI: 1.12, 4.72), food insecurity compared with security status (OR: 2.60; 95% CI: 1.45, 4.67), and household income of <$50,000 compared with ≥$100,000 (OR: 2.33; 95% CI: 1.02, 5.29). The pandemic also amplified the risk of food unavailability by household food security status (food insecure vs. secure; OR: 4.13; 95% CI: 2.12, 7.69) and across income levels (<$50,000 vs. ≥$100,000; OR: 3.48; 95% CI: 1.42, 8.55; and $50,000 to <$100,000 vs. ≥$100,000; OR: 4.00; 95% CI: 1.71, 9.34). Reported frequencies of consumption of meat, seafood, vegetables, and 100% fruit juice significantly decreased among the children post-onset of COVID-19, while frequency of consumption of sweets increased.

CONCLUSIONS

A large proportion of caregivers reported substantial COVID-19 impacts on food availability and eating behaviors of children with ASD, especially among low-resource dyads. This study highlights the added burden of existing disparities due to the pandemic on children living with ASD.

COVID-19 and behaviors in children with autism spectrum disorder: Disparities by income and food security status

BACKGROUND

Research on the impact of the COVID-19 pandemic on behaviors of children with autism spectrum disorder (ASD) is lacking.

AIMS

This study investigates the relationship between COVID-19 and behaviors of children with ASD living in the United States.

METHODS AND PROCEDURES

Parents and caregivers (n = 200) across the United States, as proxies for children 2-17 years of age with ASD, participated in an online survey querying changes in overall behavior and 15 specific behaviors during the COVID-19 pandemic. Logistic regression was used to assess the association of a moderate-to-large impact on the child's overall behavior with household income level and food security status.

OUTCOMES AND RESULTS

A majority of respondents reported a moderate-to-large impact on the child's overall behavior (74 %) due to COVID-19. Several specific behaviors were also affected. Stratifying by income level and food security status revealed disparities in the impact on overall behavior and most specific behaviors. Compared to a household income ≥$100 K, an income <$50 K was associated with an increased risk of moderate-to-large impact on the child's overall behavior (odds ratio (OR): 4.07, 95 % CI: 1.60, 10.38). Food insecurity also significantly impacted this risk, even after adjusting for potential confounding factors (OR: 3.31, 95 % CI: 1.13, 9.66).

CONCLUSIONS AND IMPLICATIONS

Our findings show a large proportion of caregivers reporting moderate-to-large changes post-COVID-19 in the behaviors of U.S. children with ASD, particularly in families with low income and/or food insecurity. This study highlights the effects of existing disparities on children with ASD and their families during this unprecedented time.

Inference making skill in children with visual impairments

There is a scarcity of research examining the reading comprehension skills of partially-sighted children despite evidence indicating that they lag behind their typically-sighted (TS) peers in reading comprehension ability. We compare the performance of children with visual impairments (VIs) with that of chronological-age matched TS counterparts on a task that requires them to make emotional, temporal and spatial inferences from short texts. The findings indicate that children with VIs exhibit a specific deficit in drawing inferences about spatial information in narratives as opposed to emotional or temporal information. The results are discussed in relation to the role of visual acuity in imagery skills and how this affects the construction of a mental model of a text.

Tracing the effectiveness of braille reading patterns in individuals with blindness: Handedness and error analysis

Braille reading is a very demanding active tactile process. Forefingers of both hands play a predominant role in braille reading, because the pulps are extremely sensitive in tactile exploration and recognition. The main objective of the present study was to investigate the potential effects of handedness on braille reading patterns during braille text reading. Thirty-two Greek students (from Grades 3 to 12) with visual impairments, who used systematically the braille code as a reading medium, participated in this study. Handedness was assessed through a modified version of the Edinburgh Handedness Inventory, while their reading level was estimated via a standardized test. In turn, participants read 18 texts, which were chosen randomly from their textbooks. Results indicated that handedness affected braille readers’ selected reading patterns during text reading. A variety of reading patterns were recorded and the selected data were correlated with tactile reading strategies in terms of dominant hands and fingers. It seems that readers who selected one-hand braille reading patterns performed significantly more errors with the index of their dominant hand, whereas those who chose to read with both hands faced more difficulties toward the effective collaboration of the indices of their hands. Finally, the findings of the present study are discussed in relation to educational practice, relevant theory, and subsequent research.

The effects of reading mode and braille reading patterns on braille reading speed and comprehension: A study of students with visual impairments in China

The purpose of this study was to examine the effects of reading mode (oral and silent reading) and braille reading patterns (one-handed pattern, mark pattern, parallel pattern, cooperative pattern) on the reading speed and comprehension of students with visual impairments in China. Seventy-three students with visual impairments aged 10-19 years participated in the study; 48 were students with congenital visual impairments and 25 were students with adventitious visual impairments. The participants' braille reading performance was assessed by the Chinese Reading Comprehension Test. Measurement indicators included reading speed (wpm) and reading comprehension. The results indicated that (1) Reading mode had a significant effect on both reading speed and reading comprehension. More specifically, although participants read faster in silent reading than in oral reading, they demonstrated better reading comprehension in oral reading than in silent reading. (2) There was a significant interaction effect between reading mode and braille reading patterns on reading speed. In particular, participants using cooperative and one-handed patterns read faster than other patterns in silent reading. This difference did not exist in the oral reading mode. (3) There was no difference between the measurement indicators of the students with congenital and adventitious visual impairments. Implications and recommendations are given based on the analyses.
