Abstract
Feedforward control is a process adjusting behaviour in a continuativeway. Feedforward takes place when an equilibrium state is disrupted andthe system has to automatically retrieve the homeostatic stable state.It also occurs when a perturbation is previewed and must be eliminatedin order to achieve a desired goal. According to the most generaldefinition, a feedforward process operates by fixing the futurerepresentation of the desired state, the achieving of which stops theprocess. Then, feedforward works by means of the refinement determinedby successive comparisons between the actual and target products. In itsapplications, a feedforward process is thought to be modulated by thesubject's purpose and the environmental state. Over the years, thefeedforward process has assumed different connotations in severalcontests of cognitive psychology. An overview of the research fields inpsychology that significantly progressed with the introduction of afeedforward paradigm is provided by: (a) reviewing models in which thefeedforward concept plays a fundamental role in the system control; (b)examining critical experiments related to the interaction of feedforwardand feedback processes; (c) evidencing practical applications for someof the presented feedforward-based architectures.
