Mechanism diagrams and abstraction-by-aggregation.

Area of Science:

• Biological sciences
• Scientific illustration
• Epistemology of science

Background:

• Mechanism diagrams visually represent biological mechanisms and their operations.
• Existing research emphasizes mechanistic explanations and models, but the role of background knowledge is underexplored.
• The contribution of non-depicted background knowledge to biological explanations via diagrams is unclear.

Purpose of the Study:

• To explore the relationship between depicted elements in mechanism diagrams and non-depicted background knowledge.
• To articulate the process by which mechanism diagrams provide mechanistic explanations.
• To investigate how background knowledge enhances the explanatory power of mechanism diagrams in biological sciences.

Main Methods:

• Conceptual analysis of mechanism diagrams and their explanatory function.
• Articulating the process of abstraction-by-aggregation in diagrammatic explanation.
• Examining the role of visual cues in accessing background knowledge.

Main Results:

• Mechanism diagrams provide mechanistic explanations through a process termed abstraction-by-aggregation.
• Visual cues within diagrams facilitate access to relevant, non-depicted background knowledge.
• This integration of visual and background knowledge leads to better-informed mechanistic explanations.

Conclusions:

• Mechanism diagrams are powerful tools for mechanistic research in biology.
• Abstraction-by-aggregation is a key cognitive process linking visual representation and background knowledge.
• Understanding this relationship enhances the epistemic value and clarity of scientific explanations.
