The main general theory of perception in cognitivism is that the distance stimulus is the object of the world, starting from our experience of the world.
Visual cognition deals with the processes by which a perceived, remembered, and thought-about world is brought into being from as unpromising a beginning as the retinal patterns.
Most of the time, cognitive psychologists take into account very tiny simple cognitive skills to evaluate into experiments, instead of more complex ones.
Neisser proposes a realistic turn in cognitive psychology, suggesting that it should target processes which are about real life and not artificial circumstances as those taken into account in most laboratory research.
Neisser suggests that if we want to build a more ecologically valid cognitive psychology, we need to take into account more complex skills such as complex decision making and ordinal life decisions.
The concept of computation was rigorized by the theory of Turing machine, a mathematical entity which components are: a control unit with a finite number of states, an infinite tape divided in an infinite number of cells, and a moving read/write head.
Economics is interested in the flow of capital, which requires an autonomy, while psychology is interested in the interference of certain facts and events but not in their material features.
One of the merits of cognitivism was that it reintroduced back issues and concepts that were removed by the behaviorist framework such as sensations, perception, imagery, retention, recall, problem solving and thinking.
Pain is caused by events in the external world (input), has causal relations with other mental states (effects on other mental states), and can contribute to causing the subject’s behavior (effects on behavior).
Functionalism has no ontological commitment on the nature of mental states, being compatible both with dualism (the mind is immaterial) and some form of physicalism (mental properties are physical properties).
Behaviorism and cognitive psychology diverge on the issue of mental states, with behaviorism denying their existence and cognitive psychology affirming their existence.
