I just have a feeling the 16/longest-marker for memory will be on one of the models, and the 16/longest-marker for psychopathology will be related to either biological explanations or treatments for OCD.
For Paper 2, we know the long/16-marker won't (or is incredibly unlikely to be) on humanism, as that's what it was on last year. And for Paper 3, we know Baillargeon won't be on the longest-marker for Cognition and Development.
