This study explores distinct levels of meaning from images of picture books perceived by 3- to 5-year-old children and investigates how the certain visual perception factors influence children's meaning making and if these factors are correlated. The literature review supports associations among visual perception, information, picture books, meaning, and children. Visual perception serves as the first channel that filters and interprets visual information, and picture books provide visual and verbal experience for children, who constantly search for meaning. Children age 3 to 5 years are potential users of picture books because pictorial information is considered useful to children's learning tasks. Previous research reveals that various factors influence visual perception, and meaning has been mostly associated with its semantic significance in information retrieval. In information science, little research has focused on young children's own way of categorizing information, especially visual information. In order to investigate the distinct levels of meaning perceived by children, the investigation employed both qualitative and quantitative methods including unobtrusive and participant observation, factor analysis, content analysis, and case study. The result of this study contributes to understanding the cognitive process of children related to visual literacy and their interpreting visual information in a digital environment.

Visual perception plays a fundamental role in a prospective learner’s ability to learn to read and spell; as well as in the accomplishment of written and numeracy tasks. Aspects of visual perception are facilitating functions and skills which a learner requires for acquiring basic literacy and numeracy proficiency. Yet, despite this importance, there exists no test that is standardised for the South African Foundation Phase population which adequately measures distinct visual perceptual aspects of individual learners. The study was undertaken in an attempt to alleviate the dilemma of the South African Foundation Phase learners who tend to experience visual perceptual challenges that hamper their level of academic learning, performance and competency. Firstly, the literature study explored the construct of visual perception and focussed on the relationship between vision, visual perception and academic learning, performance and competency. Secondly, in order to adequately measure the South African Foundation Phase population’s visual perceptual level of proficiency a new test was developed. Based on the literature study and the empirical investigation recommendations to educational psychologists, teachers, parents and learners have been made. / Educational Studies / M.Ed.

Thesis (M Sport Sc (Sport Science))--University of Stellenbosch, 2005. / The purpose of this study was to determine the effectiveness of a perceptual-motor development programme for children with Developmental Coordination Disorder (DCD), as identified on the Movement Assessment Battery for Children (M-ABC). A pre- and post-test design was employed in the study and data were reported as case studies. The programme included a cognitive approach to perceptual-motor activities, with special attention to visual perception. The intervention programme was implemented over six consecutive weeks, with two 45-minute sessions each week. The motor proficiency of nine of the 12 children who participated in this study improved to the point where they were no longer classified as having DCD. The reasons for this improvement could be attributed to the regular practise provided by the perceptual-motor activities that were the content of the program and to the method of presentation, i.e. the cognitive strategies that were child-centred, which could have helped develop self-confidence in the children. These results are in agreement with the research of Schoemaker and Kalverboer (1994) that many children with DCD may learn to overcome or cope with their movement problems. The three children who performed most poorly on the M-ABC pre-test did not improve over the course of the intervention programme. A thorough examination of their perceptual-motor system could provide more information about the various factors that may contribute to their movement problems. It is also possible that the programme simply was not long enough for these children (they did not get enough practise) and/or they were not able to respond to the child-centred cognitive approach in such a short period of time.

Visual-spatial skills deficits are one of the primary neuropsychological deficits among children with Nonverbal Learning Disability (NVLD; Rourke, 1989) and Asperger's Syndrome (AS; Ellis, & Gunter, 1999; Klin, Volkmar, Sparrow, Cicchetti, & Rourke, 1995). In addition to affecting written tasks, visual-spatial deficits also have implications for the social functioning of children. Children who are not able to accurately process visual-spatial information will have difficulty processing the visual, nonverbal cues present in social situations including facial expressions, hand movements, and body posture (Nowicki & Duke, 1992). These social perception deficits make social interactions difficult for these children. As a result of their social differences, they are likely to get negative reactions from others, have social skills deficits (Petti, Voelker, Shore, and Hayman-Abello, 2003), and have much difficulty fitting in with same-aged peers. These social skills deficits will likely lead to internalized adjustment problems in which these children feel isolated, withdrawn, and depressed around their peers. This sequence of events, visual-spatial deficits, followed by social perception deficits, followed by social skills deficits, which ultimately lead to internalized emotional problems, is implied, but not empirically proven, in a study by Petti and colleagues (2003). In addition to experiencing greater socioemotional problems than other LD subtypes, visual-spatial and social deficits of children with NVLD have been shown to worsen with age (Casey, Rourke and Picard, 1991). This dissertation study investigated the relation between these four constructs (i.e., visual-spatial skills, social perception, social skills, and internalized emotional functioning). It was hypothesized that social perception and social skills mediate the relationship between visual-spatial skills and internalized emotional functioning. In addition, these deficits were expected to increase as these children get older. As NVLD and AS are commonly co-morbid with Attention Deficit/Hyperactivity DisorderPredominantly Inattentive Type (ADHD: PI; Gross-Tsur & Shalev, 1995; Voeller, 1996), this diagnostic group was compared to children diagnosed with ADHD: PI. An additional aim of this study was to differentiate the classification of Learning Disability (LD) by demonstrating the socioemotional functioning differences between individuals with NVLD/ADHD: PI and their counterparts -- individuals with a Verbal Learning Disability (VLD/ADHD: PI). Seventy-one children, ranging in age from 8-14 participated in the study and were assigned to one of three groups (e.g., NVLD/AS with ADHD: PI, VLD with ADHD: PI, or ADHD: PI) based on pre-determined criteria. The NVLD/AS group, as expected, showed impairments in all areas (i.e., visual-spatial skills, social perception, social skills, and internalized socioemotional functioning) and significantly differed from one or both of the other groups on each of the four domains. Support was not found for the age effects for the NVLD/AS group. That is, visual-spatial and internalized socioemotional scores did not worsen with increasing age as expected. Also, visual-spatial skills were not significantly related to internalizing socioemotional functioning, and the hypothesized mediation variables were not statistically significant. The current study contributes to the understanding of individuals with NVLD, an under-studied population. The proposed visual-spatial skills deficits and social perception deficits in Rourke's (1989) theoretical model were supported. This study also offers some insight into the internalizing socioemotional functioning of children with NVLD. It clarifies the heterogeneity of socioemotional functioning among LD children, suggesting that it is children with the LD subtype, namely NVLD, who are at greater risk for social problems. / text

These diagnoses were confirmed by the Test for Visual Analysis Skills, which significantly differentiates between the normal and visually perceptually impaired. This test's validity for South African circumstances was determined in a prestudy. One hundred and six, six to nine year old subjects <82 boys and 24 girls>, of normal intelligence, visual acuity and hearing, were involved. Fifty three formed the experimental group which was subdivided in 32 who completed therapy, and 21 who did not. These pupils were individualiy matched with controls of similar sex, age, home language, socio economic status and school standard. Experimental pupils received visual therapy within a broader group context for one hour per week. Therapy periods fluctuated between 4 and 15 months. The experimental design was a pretest-posttest two group design. t-Tests for dependant <matched) groups were conducted on the differences between pre and oosttest scores, as well as between the experimental and control groups. None of the primarily visual perceptual tests revealed significant results. This signifies the inefficiency of visual perceptual therapy to rectify the deficits at which it is directed. The value of visual perceptual therapy is, on the contrary, restricted to an overall improvement in conceptualization and intellectual maturation within the group which completed therapy. Writing was the only subject which improved significantly within the same group. However, this result is dubious, due to evaluation deficits. / Psychology / D.Litt. et Phil. (Psychology)
