Externality, internality, and (in)dispensability of grammatical features in speech production: evidence from Czech declension and conjugation.
In 3 picture-word experiments, the authors explored the activation of 2 grammatical features in Czech during lexical access: declensional class of nouns and conjugational class of verbs. Experiments 1 and 2 demonstrated congruency effects of declensional and conjugational class, respectively. Picture naming times were reliably longer if the declensional or conjugational classes of the pictures' names and the distractors were incongruent. Experiment 3 explored the origin of the congruency effect in more detail. Congruency effects were obtained for declensional class regardless of whether the target name and the distractor differed in form, speaking for competition at the lemma level. These findings are discussed in comparison with gender congruency effects. The authors propose a differentiation between externally and internally specified features of lemmas, especially with respect to the time course of their activation. Internal features that become available only when the lemma is activated (e.g., gender, declensional or conjugational class of nouns and verbs) can be bypassed or not, depending on the grammatical specification of the earlier available external features (like case or number). Following this argument, supposedly inconsistent findings regarding grammatical gender and declensional or conjugational class can be explained straightforwardly.
