ENGMANN, Sonja  e  COUSINEAU, Denis. Triple redundant signals effect in the visual modality. Univ. Psychol. [online]. 2013, vol.12, n.spe5, pp.1473-1491. ISSN 1657-9267.

Response times in a visual object recognition task decrease significantly if targets can be distinguished by two redundant attributes. Redundancy gain for two attributes has been commonly found, but redundancy gain from three attributes has been found only for stimuli from three different modalities (tactile, auditory, and visual). This study extends those results by showing that redundancy gain from three attributes within the same visual modality (color, form and direction of movement) is possible. It also presents evidence that the separate activation model cannot account for such a gain.
