Verbal Interference With Visual Classification: Optimal Processing And Experimental Design, John H. Flowers, Beccy Blair Jan 1976

Verbal Interference With Visual Classification: Optimal Processing And Experimental Design, John H. Flowers, Beccy Blair

The speed of classification of six alternative ink colors into two categories of three colors each was measured in tasks for which the colors were displayed as either XXXX patterns or incongruent words (Stroop stimuli). Substantial interference from the words occurred when the classification required grouping nonadjacent hues (red, yellow, and blue vs. orange, green, and purple) regardless of whether subjects received exclusive practice with this classification. Interference also occurred when the classification required grouping adjacent hues (red, orange, and yellow vs. green, blue, and purple), but only if this classification was intermixed within blocks of trials with the nonadjacent …

The Use Of Visual And Name Codes In Scanning And Classifying Colors, John H. Flowers, Susan Dutch

The effect of incongruent color words on speed of classifying ink colors was measured in visual scanning tasks and in card sorting tasks. In both cases, little or no interference effects were noted when the classification allowed focusing on a single ink color or a set of highly similar colors (adjacent hues). Substantial interference occurred when the task required grouping of three dissimilar colors (nonadjacent hues). These findings suggest that the relative efficiency of name and visual codes in making perceptual classifications is largely dependent upon the memory requirements imposed by the task.
