“…Dopaminergic activity has also been correlated with AB magnitude. Individuals with higher spontaneous eyeblink rates, indicative of greater dopa minergic activity, had smaller AB magnitudes (Colzato, Slagter, Spapé, & Hommel, 2008). That extraversion and the AB both appear to be modulated by dopaminergic activity provides an additional reason to expect that extraversion could predict smaller ABs.…”

Accuracy for a second target is reduced when it is presented within 500 msec of a first target. This phenomenon is called the attentional blink (AB). A diffused attentional state (via positive affect or an additional task) has been shown to reduce the AB, whereas a focused attentional state (via negative affect) has been shown to increase the AB, purportedly by influencing the amount of attentional investment and flexibility. In the present study, individual differences in personality traits related to positive affect, negative affect, and cognitive flexibility were used to predict individual differences in AB magnitude. As hypothesized, greater extraversion and openness predicted smaller ABs. Greater openness also predicted higher overall target accuracy. Greater neuroticism predicted larger ABs and lower overall target accuracy. Conscientiousness, associated with less cognitive flexibility, predicted lower overall target accuracy. Personality may modulate the AB by influencing overinvestment via dispositional tendencies toward more or less stringent or capable cognitive control.

“…The majority of investigations reviewed indicated that the interaction of the conditions or groups of interest with lag was due to differences between conditions or groups at shorter, but not at longer, lags (e.g., Akyürek, Hommel, & Jolicoeur, 2007;Arend, Johnston, & Shapiro, 2007;Colzato, Slagter, Spapé, & Hommel, 2008;Rokke et al, 2002;Shapiro et al 1997b;Smith, Most, Newsome, & Zald, 2006;Stein et al, 2009). This pattern provides a clear case for concluding that the AB effect, the posttarget impairment confined to a critical period, was modulated (see Fig.…”

The attentional blink (AB) is a transient attention cost that is shown when report accuracy for a second target (T2) is reduced when T2 is presented within approximately 500 ms of a first target (T1). Thus, by definition an AB is only observed when T2 accuracy is reduced at short relative to long T1-T2 separations, and the magnitude of the AB is reflected in the change in T2 performance across target separations. However, the designs, analyses, and interpretations of several studies of the AB have suggested a lack of clear definitions about what constitutes a demonstration of the AB, what constitutes a modulation of the AB across participant groups or manipulations, and how AB magnitude might best be represented accurately as a single value for a given individual. In this article, we discuss the important conceptual and methodological issues that should be considered when obtaining, analyzing, and interpreting AB data, and we discuss the pros and cons of various approaches while providing suggestions as to how best to validly represent the AB and its modulations.

“…These patterns may be the expression of an intrinsic feature of each individual determined by mesencephalic dopaminergic activity. Although the hypothesis of blinking rate central regulation is well accepted in neuropsychology (4)(5)(6)(7)(8)(9) , there are several lines of ophthalmologic evidence showing that the condition of the ocular surface modulates the blink rate (1,(10)(11) . A classical example is the reduced blink rate that occurs after topical ocular anesthesia (12) .…”
