The similarities between the target and the intruder in naturally occurring person naming errors: a comparison between repeated and single naming confusions

This study investigated the phenomenon of personal name confusion, i.e. calling a familiar person by someone else’s name. Two types of name confusion were considered: single confusions (i.e. confusions that appeared only once) and repeated confusions (i.e. confusions that appeared repeatedly). The main purpose of the present study was to compare these two types of personal name confusion and to identify the similarities and differences between them. Participants were asked to fill in two questionnaires (one for each type of confusion) in order to collect information about the properties of the confusions. Results indicated that single and repeated confusions shared some similarities (the similarity of the gender and age of the bearers of the confused names, the phonological similarity between the confused names, the positive or negative valence of the relationship between the participant and the bearers of the names, the frequency of encountering the bearers of the names, and the low level of stress on the part of the participant when the confusions were made). However, some differences were also found between single and repeated confusions (the context of encountering, the length of time that the participant had known the two bearers of the names, the presence of the inverse confusion, the facial resemblance between the two bearers, the kind of relationship shared by the participant and the two bearers, and the state of tiredness on the part of the participant when the confusions were made). In addition, regression analysis indicated that the facial resemblance between the target person and the intruder, the phonological similarity of the names and the difference in age between the two bearer of the names were significant predictors of the frequency of the repeated confusions.
