Processing Pathways in Mental Arithmetic—Evidence from Probabilistic Fiber Tracking
Figure 5
Hypothetical model capturing the interplay between magnitude-related processing and arithmetic fact retrieval.
The figure depicts an interaction model: Basic fact retrieval related processing is assumed to be involved even in difficult arithmetic, for instance to retrieve partial results from long term memory. However, in easier tasks a larger variable component of fact retrieval may be recruited, whereas in more difficult tasks more and more magnitude-related processing is assumed.
