Beukelman(1991)提出了AAC中的魔力与交际能力成本的概念。从根本上说,这是指为了使AAC成为一种可行的通信模式(魔力)而必须付出的相对努力(成本)。许多临床医生已经看到了真正成功使用AAC的客户的魔力;这些成功也在文献中有记录。然而,在审计咨询委员会成功地为每一个客户实施之前,有必要继续查明有效使用审计咨询委员会的障碍。同年,Light和林赛(1991)主张在构造最有用的AAC符号阵列时考虑认知科学的原则。在本文中,我们考虑如何从认知科学的一个领域,即视觉认知的知识,可能会被整合到AAC符号阵列的建设。我们回顾四个领域的视觉认知,可能涉及到AAC显示器的建设:(a)组织内的刺激阵列的网格(行列配置)或集成在自然场景中,(B)符号的位置,(c)颜色和对比度,(d)对称性和轴向方向。
Beukelman (1991) introduced the concept of the magic versus the cost of communicative competence in AAC. Fundamentally, this refers to the relative effort that must be exerted (the cost) in order for AAC to be a viable communication mode (the magic). Many clinicians have seen the magic for clients who are truly successful in using AAC; such successes have also been documented in the literature. Yet until AAC is successful with each and every client for whom it is implemented, it is necessary to continue to identify barriers to its effective use. In the same year, Light and Lindsay (1991) argued for consideration of principles of cognitive science in constructing maximally useful AAC symbol arrays. In the current paper, we consider how knowledge from one area of cognitive science, that of visual cognition, might be integrated into AAC symbol array construction. We review four areas of visual cognition that might relate to the construction of AAC displays:(a) organization of stimulus arrays within either grids (row-column configuration) or integrated within natural scenes, (b) symbol location, (c) color and contrast, and (d) symmetry and axial orientation.
