Bar and Line Graph Comprehension: An Interaction of Top-Down and Bottom-Up Processes

Bar and Line Graph Comprehension: An Interaction of Top-Down and Bottom-Up Processes

This experiment investigated the effect of format (line vs. bar), viewers' familiarity with variables, and viewers' graphicacy (graphical literacy) skills on the comprehension of multivariate (three variable) data presented in graphs. Fifty-five undergraduates provided written descriptions of data for a set of 14 line or bar graphs, half of which depicted variables familiar to the population an...

Top-down and bottom-up processes in speech comprehension.

Speech comprehension includes both bottom-up and top-down processes, and imaging studies have isolated a frontal-temporal network of brain areas active during speech perception. However, the precise role of the various areas in this network during normal speech comprehension is not yet fully understood. In the present fMRI study, the signal-to-noise ratio (SNR) of spoken sentences was varied in...

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-...

Event-Related Potentials of Bottom-Up and Top-Down Processing of Emotional Faces

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...
