Abstract

Spatial representations, such as maps, charts, and graphs, convey different levels of information, depending on how their elements are grouped into different units of objects. Therefore, how people set boundaries to graphical objects to be interpreted and how they maintain the object boundaries during the given task are two important problems in understanding the way people utilize spatial representations for problem-solving. Table comprehension process was experimentally investigated in terms of eye gaze control behaviors when people were required to read off information distributed over large-scale objects, e.g., a row or a column, of the given table. Evidence was found that a large-scale object can be bounded by a single attentional shift to it, and that they can be retained as coherent objects for subsequent reference. These findings suggest the existence of a higher-order information processing in the comprehension of a spatial representation, based on rather intricate processes of attention management.
