Coordinative Dynamic of Hierarchical Visual Processing


In order to navigate and make sense of one's surroundings, a person must integrate pieces of information into larger wholes. On the flip side, the person also must be able to differentiate among more detailed pieces of information. Adaptive functioning requires the coordination of both processes, where one can flexibly switch from integrated higher-order patterns to differentiated details and vice versa. What is the nature of this coordination? Through fractal and recurrence quantification analyses used in three visual tasks (search, matching and classification), we provide evidence that this coordination has properties of dynamical systems, modulated by task features. Findings are discussed in terms of organism-environment coupling; in which local-global visual processing is conceptualized as a soft-assembled and self-organized system.
