Source monitoring is not always enhanced for valenced material.

Source monitoring for valenced materials has received very little attention from researchers interested in the residual effects that emotion can have on memory. The three previous studies that examined memory for valenced material found a source-monitoring enhancement effect. By contrast, we used two different combinations of sources and found a novel, consistent source-monitoring deficit for valenced words as compared with neutral ones. In addition, this memory deficit for contextual details did not consistently covary with item memory. We assert that it is possible to obtain an effect in which heightened attention toward valenced material reduces the binding of contextual details into memory.
