Impact of inhibition level on field-dependent and field-independent individuals in attentional blink.

The attentional blink (AB) phenomenon is a cognitive limitation that refers to the failure in identifying the second target if it follows the first one in close temporal proximity (200-500 ms). However, more recent studies have demonstrated that AB task performance greatly differs among individuals. This behavioral heterogeneity in AB has promoted research on exploring the predictive value of individual differences. The present study examined how AB magnitudes were related to personal cognitive styles. The Embedded Figures Test was carried out to classify participants' cognitive styles, along with the manipulation of the physical characteristics of distractors in the rapid serial visual presentation paradigm (RSVP) as two levels of inhibition (target-distractor similarity). Results from two experiments of varying difficulty revealed that the AB effect varied between field-dependent (FD) and field-independent (FI) individuals. The AB magnitude in FD individuals was more easily influenced by different inhibition levels of distractors, compared to the FI individuals. Results are interpreted in terms of the contemporary theories of AB that highlighted the inhibitory control over attention.
