ROSSINI, Joaquim Carlos  and  GALERA, Cesar. Stimuli selection and analysis in the visual search task. Psicol. Reflex. Crit. [online]. 2008, vol.21, n.1, pp.20-27. ISSN 0102-7972.

The capacity of processing several cognitive stages simultaneously still generates a considerable disagreement among models that try to understand the processing of visual information. Many experimental results suggest two main possibilities for the information flow between information processing stages: a discrete or a continuous flow. Two experiments have in the present study to investigate were designed attentional processing whether the information at first discarded in a pre-attentive state can influence the of selected information in a visual search task. The results show that the stimuli initially discarded in an automatic process of selection do not interfere in the attention all processing of stimuli in a visual search. The results support the models that predict an early selection of the relevant stimuli and a discrete transmission of the information between the cognitive processing stages.

Keywords : Visual search; processing stages; discrete processing; continuous processing.
