Abstract
It is known that emotion at encoding and consolidation memory can largely modulate face memory. However, how emotional cues at retrieval plays their roles remains unclear (Phaf & Rotteveel, 2005; Sergerie, Lepage, & Armony, 2007). Here we investigated the independent modulation of emotional cue on face recognition decision without the emotional impact at encoding and consolidation, and demonstrated how face recognition may be affected by facial expression at retrieval in terms of diffusion model decision biases. By comparing memory performance of angry, happy and neutral faces learned with neutral expression in a standard old/new recognition task, we found higher threshold separation (a), lower drift rate (v), lower starting point (z) for angry expression cue relative to happy expression cue, indicating a detrimental effect of angry expression cue on face recognition decision. Overall, these results suggested that an old/new decision for angry faces is characterized with the larger amount of information and the slower speed of information accumulation, which may result from the impaired holistic processing of angry faces (Curby, Johnson, & Tyson, 2012). It also indicated that a priori biases to “old” response of angry face with higher false alarm rate
