The attentional blink (AB) refers to the impairment in consciously perceiving the second of two targets presented in close temporal proximity (200 – 500ms) in a rapid serial visual presentation paradigm. The present paper is a preliminary report describing a conceptual and partially computational model of the AB based on the LIDA (Learning Intelligent Distribution Agent) cognitive architecture. The model aims to provide a biologically plausible explanation of the AB, explaining a wide range of AB-related phenomena, among other mental phenomena accounted for by LIDA. Computational results in a basic visual AB paradigm are presented and compared to human data.
