The failure to correctly report two targets ("T[subscript 1]", "T[subscript 2]") that follow each other in close temporal proximity has been called the "attentional blink" (AB). The AB has, so far, mainly been studied using experimental approaches. The present studies investigated individual differences in AB performance, revealing (among further findings) a high positive correlation between the accuracies of detecting the two targets correctly (r = 0.69); and between T[subscript 2][vertical bar]T[subscript 1] accuracy and psychometric intelligence (0.41 [less than or equal to] r [less than or equal to] 0.43) and RT variability in short-term and working memory (-0.38 [less than or equal to] r [less than or equal to] -0.45). Together, these results support important aspects of major theoretical accounts of the AB from an individual differences perspective and introduce intelligence and intra-subject stability as contributing factors in AB performance.
