The purpose of this study was to identify graphic symbols for verbs and prepositions that were performing and underperforming in static and animated formats in a recent experiment on the effects of animation on transparency, name agreement, and identification of graphic symbols. Variable-specific criteria were developed in order to define when a symbol is considered to be performing in terms of its transparency, name agreement, and identification accuracy. Additionally, across-variable heuristic criteria were developed that allowed classification of symbols into four categories: (a) performing exceptionally, (b) performing effectively, (c) performing adequately, and (d) performing inadequately. These criteria were applied to 24 symbols for verbs and 8 symbols for prepositions in both animated and static formats. Results indicated that the vast majority of the symbols performed adequately or better while a few did not. Potential reasons as to why some of the symbols may have underperformed are discussed. Where appropriate, implications for modifying existing symbols and future research are drawn. Although the fact that the heuristic criteria were developed post-hoc is discussed as a limitation, the benefits of the proposed categories bode well for future applications.
本研究的目的是确定动词和介词的图形符号,这些符号在最近的一项关于动画对透明度、名称一致性和图形符号识别的影响的实验中,以静态和动画格式呈现,表现和表现不佳。为了定义符号在透明度、名称一致性和识别准确性方面的表现,制定了特定于变量的标准。此外,还制定了跨变量启发式标准,将符号分为四类:(a)表现出色,(b)有效表现,(c)表现充分,以及(d)表现不足。这些标准应用于动词的 24 个符号和介词的 8 个符号,分别以动画和静态格式呈现。结果表明,绝大多数符号表现良好或更好,而少数符号表现不佳。讨论了一些符号表现不佳的可能原因。在适当的情况下,对修改现有符号和未来研究的影响进行了探讨。尽管事后制定启发式标准被认为是一个限制,但所提出的类别对于未来的应用是有益的。
