In 3 experiments, 9-month-old infants' expectations for what distinct count noun labels refer to were investigated. In Experiment 1, a box was opened to reveal 2 objects inside during familiarization: either 2 identical objects or 2 different objects. Test trials followed the same procedure, except before the box was opened, the contents were…

Notes that prior assumptions that writing requires phonological mediation has been questioned due to the observation that on tasks requiring the production of spoken and written responses on the same naming attempt, some aphasic subjects produce different words. The data suggest that phonological and orthographic word forms can interact. (53…

Investigated overextensions in comprehension and production, using the preferential-looking model, in 99 children (ages 1;9 to 2;3) who were asked to find the referent that matched the label they were given in real and anomalous trials. Results confirm that overextensions in production are not diagnostic of children's underlying semantic…

Many authors have argued that word-learning constraints help guide a word-learner's hypotheses as to the meaning of a newly heard word. One such class of constraints derives from the observation that word-learners of all ages prefer to map novel labels to novel objects in situations of referential ambiguity. In this paper I use eye-tracking to…

Discusses the results of an error analysis of 100 English compositions written by university students in Iran. It is suggested that mistakes are not primarily due to interference from the native language, but to developmental errors, similar to errors made in first language acquisition. (Author/AMH)
