Measuring Children's Age Stereotyping Using a Modified Piagetian Conservation Task

We examined five-year-old-children's age stereotyping using a modified Piagetian conservation task. Children were asked if two lines of objects were the "same" after one line had been made longer (transformed). A conversational account posits that children's answers reflect assumptions about the asker's motivation for the question (Schwarz, 1996). We reasoned that when asked by a young adult (puppet Experiment 1, experimenter Experiment 2) children would assume the question is to ascertain if they have noted a perceptual change and would provide answers focused on the change (length). If older adults are assumed to be in decline because of negative age stereotyping, however, children may assume an older adult (puppet, experimenter) is seeking clarification about line equality and would, therefore, give responses focused on the similarity of the lines (number). The expectation that a focus on length or number should differ across puppet/experimenter conditions was supported in both experiments and provides behavioral evidence for children's old age stereotyping.
