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 use change detection task. We applied systems factorial technology (SFT), a framework for measuring cognitive processes across multiple sources of information. Findings of coactive indicated people coordinate orientation and proximity together to make decisions. Results in line with parallel or serial processing indicated people process multiple sources of information simultaneously or sequentially before making decision.
