Cued Zone Stimuli Simulation and Model Analysis

Abstract

Attention may be a significant precursor to visual awareness but does not fulfil the sufficiency test. Moreover, the study uses a Posner endogenous spatial cueing paradigm to show that the time taken by the subject to discriminate the point of reference of a stimulus is minimized if the individual is signal towards the location of the stimulus. The reaction-time advantage is achieved without any reduction in discrimination accuracy. It implies that it cannot be said to have been caused by the speed-error trade off or distinctions in bias between the cued and uncued locations. Therefore, the subject was unaware of the stimuli to which processing was attenionally directed. In the end, the researchers conclude that attention is not a satisfactory condition for awareness.
