DESCRIPTION (provided by applicant): Many theorists currently surmise that preschool children gain key elements of emergent literacy knowledge within the adult-child shared storybook reading context, specifically an awareness of written language. Applied researchers have showed that the shared reading context is particularly amenable to conducting interventions that accelerate preschoolers' emergent literacy knowledge across a variety of domains, with a salient strategy being the adults' use of references to print. The objective of the proposed study is to inform these areas of theory and practice by characterizing the nature of and influences upon 4-year-old children's visual attention to print during adult-child shared storybook reading. The study will use eye-gaze analysis to address the following specific aims: (a) To determine the extent to which preschool children visually attend to print during adult-child storybook reading, (b) To compare the relative influence of adult verbal picture cues versus print cues upon preschool children's visual attention to print, and (c) To compare the relative influence of two different types of print scaffolds, verbal print cues and nonverbal print cues, upon preschool children's visual attention to print. Sixty 4-year-old children will participate; a within-subjects design will serve as the framework. Each child will participate in four different conditions of adult-child storybook reading, during which eye-gaze patterns will be analyzed using the Eye-Gaze Response Interface Computer Aid (ERICA). The four conditions include verbatim (adult reads storybook verbatim), verbal picture focus (adult embeds questions and comments about pictures), verbal print focus (adult embeds questions and comments about print), and nonverbal print focus (adult points to print and tracks the print). For each condition, ERICA will be used to calculate the number of visual fixations on print as well as the time spent looking at print. These two dependent variables (number of print fixations, time spent in print zones) will be analyzed across the four conditions for each child to characterize the extent to which children visually attend to print during shared storybook reading, as well as the relative influence of various adult scaffolding strategies (i.e., questions and comments about pictures versus print, verbal versus nonverbal print cues) upon children's visual attention to print in this early literacy context.

描述（由申请人提供）：目前许多理论家认为，学龄前儿童在成人-儿童共享的故事书阅读背景下获得了紧急识字知识的关键要素，特别是对书面语言的认识。应用研究表明，共享的阅读环境特别适合进行干预，加速学龄前儿童在各个领域的新兴识字知识，其中一个突出的策略是成年人使用参考印刷品。拟议的研究的目的是通知这些领域的理论和实践的特点的性质和影响后，4岁儿童的视觉注意印刷在成人儿童共享的故事书阅读。本研究将使用目光分析来解决以下具体目标：（a）确定学龄前儿童在成人-儿童故事书阅读过程中视觉注意印刷品的程度，（B）比较成人言语图片线索与印刷品线索对学龄前儿童视觉注意印刷品的相对影响，以及（c）比较两种不同类型的印刷品支架的相对影响，文字线索和非文字线索对学龄前儿童视觉注意的影响。60名4岁的儿童将参加;科目内设计将作为框架。每个孩子将参加四个不同条件的成人-儿童故事书阅读，在此期间，眼睛注视模式将使用眼睛注视反应界面计算机辅助（埃里卡）进行分析。这四个条件包括逐字（成人逐字阅读故事书），言语图片焦点（成人嵌入关于图片的问题和评论），言语印刷焦点（成人嵌入关于印刷的问题和评论）和非言语印刷焦点（成人指向印刷并跟踪印刷）。 对于每种情况，埃里卡将用于计算对印刷品的视觉注视次数以及观看印刷品所花费的时间。这两个因变量（印刷固定的数量，在印刷区花费的时间）将在四种条件下对每个孩子进行分析，以表征儿童在共享故事书阅读期间视觉上注意印刷的程度，以及各种成人支架策略的相对影响（即，关于图片与印刷品，语言与非语言印刷品线索的问题和评论）对儿童在早期识字背景下对印刷品的视觉注意力的影响。
