Eye fixation determined by the visual shape and semantic matches in language-mediated visual search
When participants are presented simultaneously a visual display with spoken input, eye fixation could be determined by a match between representations from spoken input and visual objects. Previous studies found that eye fixation on the semantic-related object and the shape competitor could be determined by the semantic match and the visual match (Huettig & Altmann, 2007). However, two matches could not be substituted by each other. Huettig and McQueen (2007) claimed the co-existence of the visual match and the semantic match in visual search. By controlling the co-presence of the target object snake and the shape competitor cable in the experiment, the visual shape competition effect has been found, although there is a semantic processing before the visual match. In other words, the preceding semantic match would not influence the visual match processing in this experiment. Due to different types of information (e.g., semantic information and visual information) from representations of spoken input and visual world are independent, the visual match and the semantic match may be independent processing in language-mediated visual search.
