Weaving in and out of this core drama a handful of vividly drawn figures add incidental color and commentary that can be compassionate or sharp.
The incidental color conjunction was more evident in the second experiment.
This response pattern demonstrates the occurrence of incidental color codification when shapes should be memorized, and their asymmetrical relationship.
However, the results of the second experiment showed no difference in the incidental color conjunction when the perceptual load was high or low, which indicates that the perceptual load does not interfere in incidental conjunction.
It is also possible that the presentation of distractors in a gradient has facilitated the prioritization of relevant stimuli and did not overload the perception as expected, maintaining the low perceptual load in both conditions, and therefore, the incidental color conjunction.
It is possible that these differences between results can be attributed to minor differences in procedure, for example, the use of animal figures and longer retention intervals, which may have allowed a contribution from the long-term memory to override the effect of incidental color conjunction.
Our results also show that the increase in perceptual load obtained by introducing irrelevant items during the presentation of colored shapes has no effect on the incidental conjunction of color.
Ecker et al. (2013) conversely, found evidence of incidental conjunction of color and shape, but only in conditions in which the color was intrinsic to the memorized figure.
Therefore, the objective of this first experiment was to verify the incidental conjunction between color and shape, and a possible asymmetry in a recognition task for colors and shapes.
In conclusion, our results suggest the occurrence of an incidental conjunction of color and shape.
