RESUMEN
Attribute amnesia (AA) is a phenomenon in which participants have difficulty answering an unexpected question about an attended attribute of the most recent target stimulus. A similar situation can occur in cases of real-life eyewitness identification when the eyewitness did not explicitly try to remember the alleged perpetrator's face despite having attended to it. We found that AA is generalizable to novel faces, such that when participants were unexpectedly asked to identify a face, performance was poor, even though they had just attended to that face seconds ago (N = 40 each in an initial experiment and its replication). This finding shows that unexpected face identification is inaccurate even when the face had just been attended to and suffered minimal decay and interference, implying that AA can explain some cases of failure of eyewitness identification that cannot be attributed to a lack of attention or post-event interference.
