N2 - Recently a novel interference task was developed, that was aimed at obtaining robust patterns of interference in individual subjects, both behaviorally and neurophysiologically (Bush, Shin, Holmes, Rosen & Vogt, 2003). This multi-source interference task (MSIT) combined elements of spatial and flanker interference, and huge interference effects were obtained in a blocked design. This task could thus in principle be used to assess frontal abnormalities, such as ADHD. In the present study, we further examined the nature of the MSIT. We examined the effect of randomization, and the relative contribution of each type of interference. Using a group of healthy subjects, we found a much smaller interference effect than Bush et al. (2003). In addition, we found that most of the interference could be ascribed to flanker interference, and much less to spatial interference. It seems to be the case that there is a trade-off between obtaining robust and reliable effects, and isolating a specific psychological process. Copyright © Taylor & Francis Ltd.
