A long-awaited book from developmental disorders expert John Morton,
Understanding Developmental Disorders: A Causal Modelling Approach makes sense of the many competing theories about what can go wrong with early brain development, causing a child to develop outside the normal range.
- Based on the idea that understanding developmental disorders requires us to talk about biological, cognitive, behavioral and environmental factors, and to talk about causal relationships among these elements.
- Explains what causal modelling is and how to do it.
- Compares different theories about particular developmental disorders using causal modelling.
- Will have a profound impact on research in the fields of psychology, neuroscience and medicine.
