Boundaries of the relation between conscious recollection and source memory for perceptual details

The relation between conscious recollection and source memory for perceptual details was investigated in three experiments that combined the remember–know paradigm with a multidimensional source monitoring test. Experiment 1 replicated that source memory for perceptual details is better in the case of “remember” than “know” judgments. Experiment 2 showed that the relation between “remember” judgments and source memory for perceptual details is diminished by a semantic orienting task during encoding. Experiment 3 demonstrated that “remember” judgments are related to enhanced source memory for specific and unique kinds of perceptual source information, whereas memory for incomplete and global perceptual source information does not differentiate between “remember” and “know” judgments. The results show that the attentional focus during encoding and the specificity of retrieved source information form boundary conditions for the use of source memory for perceptual details as a basis of “remember” judgments.
