Experimental Investigation on Top-down and Bottom-up Processing in Graph Comprehension and Decision
Graph comprehension requires both bottom-up processing
from the graph representation and top-down processing guided
by knowledge and attitude. In the current study, we
investigated which of the bottom-up process phases: extraction,
interpretation, and decision: were affected by the top-down
processing derived by the impressions and social attitudes. The
experimental results showed that the top-down processing
driven by impressions temporarily formed in specific contexts
affected both the extraction of information and the following
decision phase whereas top-down processing driven by attitude
formed over a long time based on social norms affected only
the decision phase. In the latter case, a decision was made
without any need for bottom-up processing
