Abstract:
In this paper, we conduct two word learning experiments to study the human word learning and generalization behaviour. The participants are shown abstract figures that form the positive examples of a word concept. All the positive examples have a common defining feature. The participants are then asked whether the word applies to various test examples. We vary several independent variables across our two word learning experiments. Our results show that the word generalization behaviour is based on the similarity of a test example with the positive examples of a word. The generalization behaviour is not based on the defining features. This is true even when enough examples exist from which the defining features can be inferred.
