The effects of acoustic mismatch and selective listening on repetition deafness.
Previous research (i.e., M. Miller & D. O. MacKay, 1994, 1996) has suggested that repetition deafness (RD), like repetition blindness, is robust to physical identity and that it consists in a failure to recall specifically the 2nd of the 2 critical targets (C1 and C2). However, some confounds due to memory load and response biases make available evidence inconclusive. Experiment 1 provided a strong test of RD between physically mismatching stimuli using a low memory load methodology. In Experiment 2, the same presentation method was combined with a selective recall task to find that RD is specific of C2. Experiments 3A and 3B showed, through an attentional manipulation, that RD is eliminated when people can successfully ignore C1 but not otherwise. It is argued that present data favor a perceptual interpretation of the RD. Furthermore, the present results support the hypothesis of recognition failure as opposed to the alternative token individuation failure hypothesis.
