The present study evaluates the contribution of visuo-gestural modality versus linguistic factors in determining the order of elements in sign language. The same picture description task was given to 12 hearing subjects using spoken Italian, 12 deaf subjects using Italian Sign Language, and 12 hearing subjects using pantomime. Nonreversible, reversible, and locative productions with two elements were elicited. The results showed that Italian Sign Language differs along significant lines from both spoken Italian and pantomime. The pattern of similarities and differences found among the three experimental conditions allows us to argue that the order of signs in the sentence is sensitive to modality as well as linguistic factors depending on the particular sentence structures considered.

An African Grey parrot, Alex, who had learned to use English speech in studies on referential interspecies communication and animal cognition, produced English monologues in both the presence and absence of human receivers. This study examines one component of Alex’s monologue behavior, private speech, while he was being taught new vocalizations. His private speech during those time periods included a small percentage of novel utterances, not yet used in the presence of his caretakers, that were phonologically related to, but not exact reproductions of, the new vocalizations. His monologues also contained utterances that were part of the general daily routine as well as the specific training paradigm, but rarely included verbatim reproductions of the training scenario. Alex’s behaviors were comparable to those of children in the early stages of language acquisition. Because monologue behavior has been characterized as a form of practice that facilitates human language development, the data are discussed in terms of the possible functions of monologues during Alex’s acquisition of novel vocalizations.

This report presents the results of the second year of a 4-year longitudinal evaluation of a partial French immersion program in Cincinnati, Ohio. This program is of particular interest because it includes children from lower socioeconomic group and ethnic minority group (black) backgrounds in addition to majority group (white), middle-class students who have been the subject of virtually all evaluations of immersion to date. The native language development (English), academic achievement (math), and second language attainment (French) of pilot groups of middle- and working-class students and of black and white students who were in grade 1, as well as those of a follow-up cohort of kindergarten students, were assessed. The results showed that performance differences in English and mathematics between subgroups of students did not depend on the program of instruction they were receiving. Moreover, it was found that the working-class and black students scored as well as the middle-class and white students on the French language tests. The results are discussed further in terms of the immersion students’ level of proficiency in French.

A group of 54 children with specific language impairment was compared with a control group on a referential communication task in which the child was asked to describe a picture from an array of eight similar items so that the listener could identify it. The language-impaired children performed more poorly than age-matched controls. However, there was no relationship between referential communication performance and conversational ability. Children who provided excessive and irrelevant information in conversation did not show the same characteristics in the experimental setting. Formal task requirements, such as the need to scan an array, appeared to be a major determinant of performance on structured referential communication tasks. These tasks are not sensitive to the types of pragmatic difficulty that some children have in open-ended conversation.

This study explores the development in children of dual-level phonological processing. Evidence suggesting that 6-year-olds form underlying representations composed of morphophonemic segments was obtained by asking children to imitate complex words, omit specified portions, and discuss the meaning of the resulting word parts. Trial items represent a variety of instances in which phonetic forms differ from underlying representations. Although language-advanced first graders produced stronger evidence suggesting morphophonemic segments than language-delayed age-mates, and young adults supplied stronger evidence than either first-grade group; strength of evidence leads to the interpretation that even language-delayed 6-year-olds form morphophonemic segments. Differences in performance between groups probably derive from differences in metalinguistic abilities and linguistic experience rather than from differences in units of phonological processing.
