Stimulus alignment and age in the selection of bigger rectangles.
90 children (28 3-yr.-olds, 32 5-yr.-olds, and 30 8-yr.-olds) were presented pairs of quadrangles with the bases or the centers aligned and asked to select the bigger ones. 3- and 8-yr.-olds selected larger ones under both aligned conditions, while 5-yr.-olds selected the taller ones more often under the base- than under the center-aligned conditions. 5-yr.-olds selected the larger ones less often than 3- and 8-yr.-olds under the base-aligned condition. These results were discussed in relation to the attention given to height.
