Experimental investigation of effects of representations and contexts on comprehension and generation of line graphs

Abstract: In this study, we investigated the representation effect in comprehending graphs.Many previous studies have confirmed the representation effect.In Experiment 1, we replicated the representation effect but using a set of graphs each of which is completely identical from the other in its perceptual characteristics.Participants drew a specific aspect of information from a line graph depending on the relation of x-axis and z-legend of the graph.In Experiment 2, participants were given a context for problem solving.The result showed that participants read a graph based on a given context; and the representation effect in comprehension was limited.In Experiment 3, participants generated a line graph by themselves.The result showed that they did not necessarily generate a consistent graph with a given context, and in comprehension the requirement of a context has very strong effects similarly as in Experiment 2.
