Experimental Investigation on Top-down and Bottom-up Processing in Graph Comprehension and Decision
نویسندگان
چکیده
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.

Introduction: Emotional stimulus is processed automatically in a bottom-up way or can be processed voluntarily in a top-down way. Imaging studies have indicated that bottom-up and top-down processing are mediated through different neural systems. However, temporal differentiation of top-down versus bottom-up processing of facial emotional expressions has remained to be clarified. The present st...
