THE INFLUENCE OF EXPERIMENTER ATTITUDE ON THE PERFORMANCE OF CHILDREN OF DIFFERENT COGNITIVE-ABILITY LEVELS

We investigated the influence of the experimenter’s attitude on children’s performance in a classification task. We chose 96 children (M age: 5 years, 9 months) on the basis of their performance in a spontaneous classification task. Fortyeight children made partial alignments on the basis of a link established from one object to the next (O-level group); 48 looked for objects having one common property (P-level group). The children had to perform a dichotomy task in two testing situations: One with a caring experimenter, and one with an indifferent experimenter. In the O-level group, the children’s performance was superior when the experimenter was caring even though they did not seem to notice the difference between the two attitudes. P-level children clearly distinguished the experimenter attitudes, but their performance remained the same. To determine children’s actual abilities accurately, researchers must take into account children’s interactions with both objects and partners. © 1990 Taylor & Francis Group, LLC.
