Investigating the Integration of Two Sources of Visual Information
Researchers suggest emergent features are fundamental to visual processing. Earlier work examined the perception of combined local information in terms of the emergent features (i.e., orientation and proximity). Our current study investigated how those emergent features combine together. To examine this question, we used change detection task. We applied systems factorial technology (SFT), a framework for measuring cognitive processes across multiple sources of information. Findings of coactive indicate people coordinate orientation and proximity together to make decisions. Results in line with parallel or serial processing indicated people process orientation and proximity of information simultaneously or sequentially before making a decision. The result indicates that people process emergent features separately.
