The attentional biases toward body-related information for individuals with weight concerns and eating disorders have been well documented. However, our knowledge of the attentional biases toward body-related information for subjects with physical stature concerns is only at the beginning. And the research on the auditory attentional biases for individuals with physical stature concerns is rare. The identification of attentional biases may provide an impetus for interventions to reduce distress among height dissatisfied individuals. Therefore, the present study investigated the neural mechanisms of attentional bias toward auditory physical stature-related words among height dissatisfied young males by using event-related potential recordings. Forty-four young male participants screened by Negative Physical Self Scale-Stature Concerns subscale (NPS-S) were assigned into an experimental group with high levels of height dissatisfaction (HHD) and a control group with low levels of height dissatisfaction (LHD). Task irrelevant auditory tall-related words, short-related words and neutral words were presented unilaterally to the participants as the cue in a cue-target paradigm. Participants were required to respond to the visual target preceded by the task-irrelevant auditory cue. The results found that significantly larger N2ac was elicited by tall-related words than short-related words and neutral words only for the HHD group, but not for the LHD group. LPCpc amplitudes did not differ significantly by the functions of word types and experimental groups. These results suggest an attentional orienting bias toward auditory tall-related words for young males with high levels of height dissatisfaction.
