It is well known that English and Dutch children often allow pronouns to refer to local ccommanding antecedents, the so-called Principle B Delay. A similar observation has been made for English agrammatics. This phenomenon, which we call the Pronoun Interpretation Problem (PIP), has been argued to be due to children's and agrammatics' difficulties…

Previous studies have shown that an aphasic patient (AB) with a semantic short-term memory deficit (STM) had difficulties comprehending and producing sentences with structures that demanded the simultaneous retention of several individual word meanings (Martin & Freedman, 2001a, 2001b; Martin & Romani, 1994; Martin, Shelton, & Yaffee, 1994). The…

We report results of an experimental study with Dutch agrammatic aphasics that investigated their ability to interpret pronominal elements in transitive clauses and Exceptional Case Marking constructions (ECM). Using the obtained experimental results as a tool, we distinguish between three competing linguistic theories that aim at determining…

We tested the effects of multiple exemplar instruction (MEI) on the emergence of untaught mands or tacts of adjective-object pairs in a multiple-probe design across four students with autism/developmental disabilities. None of the students emitted either mands or tacts for three sets of three adjective-object pairs (word sets counterbalanced…

In two eye-tracking experiments the role of contrastive pitch accents during the on-line determination of referents was examined. In both experiments, German listeners looked earlier at the picture of a referent belonging to a contrast pair ("red scissors," given "purple scissors") when instructions to click on it carried a…

We report the results of an experiment investigating the ramifications of using space to express coreference in American Sign Language (ASL). Nominals in ASL can be associated with locations in signing space, and pronouns are directed toward those locations to convey coreference. A probe recognition technique was used to investigate the case of…

If people believe that some property is true of all members of a class such as sofas, then they should also believe that the same property is true of all members of a conjunctively defined subset of that class such as uncomfortable handmade sofas. A series of experiments demonstrated a failure to observe this constraint, leading to what is termed…

Data from child language comprehension show that children make errors in interpreting pronouns as late as age 6;6 yet correctly comprehend reflexives from the age of 3;0. On the other hand, data from child language production show that children correctly produce both pronouns and reflexives from the age of 2 or 3. Current explanations of this…

This study reports the results of a picture verification task assessing the interpretation of intra-sentential anaphora and cataphora in Italian by a group of English-Italian bilingual eight-year-olds, a group of age-matched Italian monolinguals, and a group of Italian monolingual adults. No significant differences between the groups were observed…

In three experiments we investigated the locus of the frequency effect in lexical access and the mechanism of gender feature selection. In Experiment 1, participants were asked to produce gender-marked verb plus pronominal clitic utterances in Italian (e.g., "portalo" (bring it [masculine]) in response to a written verb and pictured object. We…

Idiom comprehension was assessed in 10 aphasic patients with semantic deficits by means of a string-to-picture matching task. Patients were also submitted to an oral explanation of the same idioms, and to a word comprehension task. The stimuli of this last task were the words following the verb in the idioms. Idiom comprehension was severely…

Microelectrode recordings of human sensori-motor subthalamic neuronal activity during spoken sentence and syllable-repetition tasks provided an opportunity to evaluate the relationship between changes in neuronal activities and specific aspects of these vocal behaviors. Observed patterns of neuronal activity included a build up of activity in…

In Study 1, English-speaking 3- and 4-year-olds heard a novel adjective used to label one of two objects and were asked for the referent of a different novel adjective. Children were more likely to select the unlabeled object if the two adjectives appeared prenominally (e.g., "a very DAXY dog") than as predicates (e.g., "a dog that is very DAXY").…

In two eye-tracking experiments, we investigate adults' and children's on-line processing of referentially ambiguous English pronouns. Sixteen adults and 16 four-to-seven-year-olds listened to sentences with either an unambiguous reflexive ("himself") or an ambiguous pronoun ("him") and chose a picture with two characters that corresponded to…

This paper investigates object omission in French longitudinal production from two English-speaking children (Lightbown, 1977). Similar patterns of object omission are observed: direct objects start being dropped as transitive verbs are emerging and licit and illicit null objects occur in all recordings thereafter. Moreover, the incidence of…
