ABSTRACT
Trajectory paths in walking seem to be highly determiner in agreement with the generalization that organisms easily and promptly counteract and correct slight deviations from some internalized form of desired paths in natural locomotion. Accounts of trajectory path determination might require constructs that refer to internal control of a series of specific views appearing in perceptual awareness and based on invariant object structure. Maximal control should refer to a path between an initial view and a terminal view that matches a target view specified as such by perceptual activity in a past event. Limitations of capacity for perceptual view reinstatement in task conditions may depend on the functioning of an internalized model of target-specifying perceptual activities tied to a past event, feedforward determining a predictive quality of implicit visualization activity that terminates in expected view(s) and aiming point(s) followed by goaldirection-intrinsic feedback from perceptual views during path progression. These compromise premises, as compared to other approaches (cf. Gibson, 1979; Hollerbach, 1990), guided the following research.
