skallmodell

A skallmodell is a term used in certain academic and theoretical contexts, particularly within philosophy and cognitive science, to describe a conceptual framework or model that emphasizes the functional aspects of a system rather than its underlying physical implementation. The term originates from the Swedish word "skal" meaning "shell" or "layer," suggesting a focus on external behavior or observable interactions.

In essence, a skallmodell treats a system, such as a mind or a computational process, as a series of nested or interacting layers. Each layer is defined by its inputs, outputs, and the rules governing its transformations, without necessarily specifying the exact nature of the hardware or biological substrate that carries out these operations. This allows for a level of abstraction, enabling the study of cognitive functions or system behaviors independent of their specific realization.

For instance, in artificial intelligence, a skallmodell might describe a vision system by outlining distinct modules for edge detection, object recognition, and scene understanding, focusing on the data flow and processing logic between these modules. The actual algorithms or neural network architectures used within each module are secondary to the overall functional architecture.

The utility of skallmodelle lies in their ability to facilitate understanding and comparison across different systems. By abstracting away from specific implementations, researchers can identify common functional principles and structures that may be present in diverse systems, whether biological or artificial. This approach is central to computational theories of mind and functionalism, which propose that mental states are defined by their causal roles rather than their physical composition.
