Research has found that faces of own-age group members tend to be detected earlier in attention and retained longer in memory than faces of other-age group members (referred to as the own-age bias). However, few studies have looked at the moderation of perceivers mood state and face emotions on the own-age bias in attention and memory. Aim: The present study was aimed at examining the own-age bias in attention and memory, as well as the moderation effect of perceivers mood and the emotional valence of the face images, with sufficient cognitive resources at the encoding phase (Study 1), and with insufficient cognitive resources at the encoding phase (Study 2). Method: College student participants were randomly assigned to three conditions to induce positive, anxious or neutral mood. Participants performed a face attention task, and encoded the faces with insufficient cognitive resources (Study 1) or with sufficient cognitive resources (Study 2). Participants were then surprised by a face recognition memory task. Results: In both studies, significant own-age biases were found in memory false-alarm rate and response tendency (C), but were not found in attention reaction time, memory hit rate, and memory discriminability (d'). In addition, there was an angry-potentiated effect for own-age bias in both Study 1 and Study 2, such that the own-age bias in false-alarm rate and response tendency of recognizing face emotion was more prominent for angry face emotion than happy and neutral face emotions. Finally, perceivers mood moderates the own-age bias in response tendency of recognizing face emotions: the own-age bias was only present under anxious mood but not present under positive or neutral mood. Conclusion: The own-age bias in memory and the angry-potentiated effect on the own-age bias were robust both when faces were encoded with sufficient cognitive resources and when faces were encoded with insufficient cognitive resources. The findings have important implications for future research on the own-age bias in cognitive processing of emotional faces, and intergenerational interactions in daily life.
