  • Title: Information integration in an area judgment task: effect of aids on children's perceptual judgments.
    Author: Mullet E, Lautrey J, Glaser PL.
    Journal: J Genet Psychol; 1989 Dec; 150(4):375-88. PubMed ID: 2625633.
    Abstract:
    This study was designed to examine the cognitive processes involved in perceptual judgments of area with the methodology and concepts of Anderson's (1981) information integration theory. The Area = Height + Width rule, which Anderson and Cuneo (1978) showed to be operant in children's judgments, can in fact cover two different processes. Children may make a height judgment and then a length judgment and apply an additive integration operation to both. Alternatively, children may base themselves on the figure outline and estimate total length directly as a function of the distance scanned. Similarly, the multiplicatory integration pattern can result either from applying a multiplicatory operation to separate estimates or from visual exploration of the area bounded by the figure. In the present experiment, the characteristics of the areas of the test figures were modified (perimeter marking, rows of Xs covering the area, etc.) to elicit additive or multiplicatory integration patterns as a function of condition. The findings demonstrate that the second interpretation of both rules is more likely.
