Purpose. The purpose of this study was to investigate the cognitive development of visually impaired children in the Republic of China, as measured by Piagetian tasks of conservation. / Procedure. Eighty children, age 6 through 15, with varying degrees of vision loss, and 40 sighted children, age 6 through 15, were randomly selected, using a stratified constant procedure. Each child was presented individually with eight tasks of conservation including number, length, distance, substance, liquid quantity, area, weight, and displacement volume. Each task included one transformation. The subjects were identified as conservers or nonconservers for each task. / Methods. (1) Discriminant analysis techniques were used to classify individuals into one of two groups (conserver, nonconserver) on the basis of age, vision, gender, and residence; and to identify which variables contribute to making the classification, (2) The order of difficulty of eight conservation tasks were analyzed descriptively by determining the percentage of children who passed for each task, (3) The percentage of children who passed each task by age level was presented in table form, (4) Explanations given by the children were analyzed descriptively. Responses were categorized and presented in table form. / Results. (1) Age and vision were two significant variables contributing to the attainment of conservation. Younger visually impaired children were more apt to be nonconservers, (2) The order of difficulty of eight conservation tasks for the partially sighted children was more similar to that of the sighted children than to that of the blind children, with the blind children differing greatly from both the partially sighted and sighted children, (3) A one to four year developmental lag in the attainment of eight conservation tasks was found in blind children compared to the sighted and partially sighted children, (4) Blind children made up these developmental delays at the age of 11, (5) The explanations given by the conservers among the sighted, partially sighted, and blind children were similar; however, the explanations given by the blind and partially sighted nonconservers demonstrated more variability than the sighted nonconservers. / Source: Dissertation Abstracts International, Volume: 47-05, Section: A, page: 1693. / Thesis (Ph.D.)--The Florida State University, 1986.
