Abstract: | Thirty-two spider-fearful, 33 blood/injury/injection fearful, and 28 non-fearful individuals (N = 93) participated in dual-task study. Participants were presented with blood, spider, neutral, positive and pseudo-word stimuli while having to also verbally identify numbers as either even or odd. Blood-fearful individuals responded slower than spider and non-fearful individuals. However, there was no interaction of group membership with stimuli type. This study replicates the results of two previous studies that have used a lexical decision task in an effort to differentiate between fearful and non-fearful individuals and found no significant differences between these two groups on this task. These results suggest that the lexical decision task in general may not be sensitive enough to elicit processing differences in non-clinical samples. |
