Asymmetric recognition of pictures of cats as a function of age in 4-, 5-, and 6-year-old children.

In the present study it was investigated whether children recognized deletions more accurately than additions in pictures of animate objects as a function of age between 4 and 6 years. Children, presented pictures of cats with features added to or deleted from the original pictures, judged whether the pictures were the same or different as those in a test of recognition. Analysis showed both 5-yr.-olds and 6-yr.olds discovered deletions more accurately than additions. This asymmetric effect is in accord with that of adults, with whom the same stimuli were used in earlier research, but are contrary to previous studies in which additions were recognized more accurately than deletions when inanimate objects were stimuli. Asymmetric effects, that is, greater recognition accuracy for deletions may be related to children's being uncomfortable about modified pictures of animals.
