Testing the Labeling Effect in Autistic Children.

PURPOSE

Our objective was to test the labeling effect in autistic children. The effect has been robustly tested in typically developing (TD) individuals. TD children expect that any two objects that receive the same linguistic label will have similar properties, which suggests that they generate concepts based on acts of labeling. The labeling effect has not been tested on autistic children, who may not be equally attuned to the relevance of linguistic clues or may not generalize as swiftly as TD children.

METHODS

We reproduced Graham et al.,'s (Frontiers in Psychology 10.3389/fpsyg.2012.00586, 2013) design on 30 autistic children of different ages. Participants were divided into two groups depending on whether objects presented to them were named alike or differently (Same or Distinct Label between-individuals condition). The dependent variable was the number of target actions the child performed on an object, depending on whether that object made the same sound as a previously shown test object.

RESULTS

We did not reproduce results similar to those reported in Graham et al., (Frontiers in Psychology 10.3389/fpsyg.2012.00586, 2013). Children in the Same Label group did not perform significantly more actions than children in the Distinct Label group when the objects that were handed to the children did not make the same sound as the test object.

CONCLUSIONS

Autistic children do not seem to be sensitive to the labeling effect to the same extent as TD children. If these results are confirmed, intervention programs for autistic children should consider trainings on this way of generating concepts shared by their linguistic community.
