Влияние легкости называния признаков объекта на научение новым категориям

Nameability (ease of naming an object or a feature) is one of the factors supporting new category formation. The effect of a part’s nameability (Zettersten and Lupyan, 2018) depends on the greater success of defining a visual categorical feature of an object part, such as color or shape, among different features with basic names (e.g.,“red”) than among the features with less basic names (e.g, “mustard”). In this study we replicated this effect, and additionally we showed that it is restricted by the type of category rule: the nameability of features did not improve the accuracy of learning in the condition with probabilistic rules. But the nameability of features improved the accuracy of learning in the condition with rules based on one categorical feature. In the second experiment we showed that a verbal interference task eliminates this effect in learning the rules based on one categorical feature. In summary, our results explain how verbal processes (availability of names in long- term memory and verbalization) help us to learn new categories.We discuss the possible sources of the effects of nameability on category learning in the course of ontogenetic development.
