DYNAMIC FIELD THEORY OF SEQUENTIAL EFFECTS
Dynamic Field Theory (DFT; Erlhagen & SchÃ¶ner, 2002) provides a framework how sensorimotor and perceptual decision making may arise from population representations by taking into account principles of Dynamic Systems Theory (SchÃ¶ner, 2002). From a theoretical standpoint decision making may be divided into estimation â€“choosing from a continuum of choices by estimating the current stimulus value â€“ and categorization â€“sorting the stimulus value into a finite number of discrete categories based on preinformation. DFT provides a framework how current stimulus information and preinformation may be flexibly combined and weighted according to current situational constraints (Wilimzig, 2006; Wilimzig & SchÃ¶ner, 2006) such that the system may flexibly switch between estimation and categorization behavior. Sequential effects emerge from the representation of preinformation in this account.
