The study investigated attentional processes of 32 preschool children with congenital visual impairment (VI). Children with profound visual impairment (PVI) and severe visual impairment (SVI) were compared to a group of typically developing sighted children in their ability to respond to adult directed attention in terms of establishing, maintaining, and shifting attention on toys. The measures of children's sensory‐motor understanding (SMU) and language ability were obtained using the Reynell‐Zinkin scales of mental development. The video‐recordings of these play‐based assessments were coded for three categories of behavioural responses (Establish, Maintain, and Shift). The three groups were matched on verbal comprehension (VC), but differed significantly in their SMU and their chronological age. The groups of children with PVI and SVI were found to be comparable in their ability to establish and maintain attention on objects. Despite a relatively good performance overall both groups scored significantly lower on those skills than children who were sighted. However, with regards to attention shifting, children with PVI showed significantly lower performance than both the children with SVI and the sighted children who were similar on this component. Ability to maintain and shift attention was significantly related to the cognitive ability of children with PVI; however the poorer attentional responses were not confined only to the children with low IQ. The results are discussed in relation to the role of vision, cognitive ability and executive function in attentional processes in children with congenital VI. 相似文献

Freud's assertion notwithstanding, the attachment relationship is not “without parallel” in social life. Children's attainments in forming attachments to parents parallel the steps they take in relating to their peers. During the first 3 years of life, in both domains, infants come to recognize prospective social partners, communicate with them, engage them in patterned interaction, including both cooperation and conflict, learn from their presence and actions, and interact in idiosyncratic ways with particular companions. Toward the end of this period, children show signs of acquiring generalized concepts of the social relationships in which they engage. It is proposed that biological constraints on learning promote human infants' interest in and rudimentary abilities to interact with other members of their species. Subsequent incidental and intentional learning processes shape both the child's attachments and less intense relationships with other persons. 相似文献

ABSTRACT Second, third, and fourth grade children were administered one of three different versions of a word identification test. All versions tested the same target words but used a different combination of two different sets of distractor words. One set was deemed “highly confusing” (i.e., all dis‐tractors were graphically very similar to target words), the other “easily discriminable” (i.e., distractors were dissimilar to target words). One test version contained all highly confusing distractors, a second used all easily discriminable distractors, and a third contained a combination of both kinds. Results showed that at all grade levels children performed significantly better on the easily discritninable version than on the highly confusing version. Implications of this finding related to the content validity of extant word identification tests; that is, if test authors do not use a set of criteria for selecting distractor words and apply these criteria consistently, the content validity of a test may be in serious jeopardy, for one would not know whether the test measures target word difficulty of distractor word difficulty 相似文献
