Is inattentional blindness related to individual differences in visual working memory capacity or executive control functioning?

Inattentional blindness (IB) research deals with situations where, under focused attention tasks, salient stimuli that are irrelevant to that task do not reach conscious awareness Although such research has captured popular imagination, to date very little research has been conducted on whether some are more likely to experience this phenomenon than others Here we provide evidence that working memory capacity (WMC) contributed to this experience, with lower WMC being predictive of IB We also investigated whether IB could be more readily explained in terms of domain-specific visual WMC No group differences in visual WMC were found, nor any differences in the ability to perform the primary IB task These findings suggest that differences in higher-order executive control of attention contributes to the experience of IB
