Neurolinguists, beware! The bilingual is not two monolinguals in one person.

Two views of bilingualism are presented--the monolingual or fractional view which holds that the bilingual is (or should be) two monolinguals in one person, and the bilingual or wholistic view which states that the coexistence of two languages in the bilingual has produced a unique and specific speaker-hearer. These views affect how we compare monolinguals and bilinguals, study language learning and language forgetting, and examine the speech modes--monolingual and bilingual--that characterize the bilingual's everyday interactions. The implications of the wholistic view on the neurolinguistics of bilingualism, and in particular bilingual aphasia, are discussed.

Aphasia

A study of timing in a manual and a spoken language: American sign language and English.

A comparative analysis of the time variables in the production of speech and sign reveals that signers modify their global physical rate primarily by altering the time they spend articulating, whereas speakers do so by chaning the time they spend pausing. When signers increase or decrease their pause time, however little they do so, they alter the number and the length of the pauses equally, whereas speakers primarily alter the number of pauses and leave their pause durations relatively constant. An analysis of the durations of signs reveals that signs are longer at the end of sentences than within sentences and that the first occurrence of a sign is longer than the second when syntactic location is controlled (both these findings have already been reported for spoken language). The inherent duration of a sign can be accounted for almost totally by the movement characteristic; handshape, location, and number of hands in a sign are of little importance. Finally, signers retain their regular "quiet-breathing" respiratory pattern across signing rates and inhale at locations independent of syntactic importance. In this they are quite unlike speakers, who breathe at syntactic breaks.

Adult

Breathing, pausing and reading.

An analysis of the breathing patterns of speakers in a variable-rate reading task shows that the duration and frequency of breathing pauses are dependent both on the rate of speaking and the syntactic nature of the pause location. Non-breathing pauses follow the same pattern of occurrence as breathing pauses, but are always shorter and tend to occur primarily at minor constituent breaks. At slow and normal rates, speakers accommodate their need to inhale to the preplanned pause patterns. At fast rates, however, the physiological need to breathe is the sole determinant of pausing.

Female

How the listener integrates the components of speaking rate.

The rate of speaking in words per minute is a function of three independent variables, namely, articulation rate and the number and durations of pauses. The present study varies each of these components separately in a factorial design in order to determine how the listener combines them into a global impression of speech rate. A model was obtained by direct scaling and linear regression that accounts reasonably well for the estimates of apparent rate obtained in this and several other studies. It provides for a trading relation between articulation rate and pause rate in which the former is much more influential in determining the listener's perception of speech rate.

Acoustic Stimulation

Base-language effects on word identification in bilingual speech: evidence from categorical perception experiments.

The categorical perception paradigm was used to investigate whether French-English bilinguals categorize a code-switched word as French or English on the basis of its acoustic-phonetic information alone or whether they are influenced by the base-language context in which the word occurs, that is, by the language in which the majority of words are spoken. Subjects identified stimuli from computer-edited series that ranged from an English to a French word as either the English or the French endpoint. The stimuli were preceded by either an English or a French context sentence. In accord with previous studies (Grosjean, 1988), it was found that the base language had a contrastive effect on the perception of a code-switched word when the endpoints of the between-language series were phonetically marked as English and French, respectively. When the endpoints of the series were phonetically unmarked and thus compatible with either language, however, no effect of the base language was found; in particular, we failed to find the assimilative effect that has been observed with other paradigms (Grosjean, 1988; Soares and Grosjean, 1984; Macnamara and Kushnir, 1971). The current results provide confirming evidence that the perception of a code-switched word is influenced by the base-language context in which it occurs and, moreover, that the nature of the effect depends on the acoustic-phonetic characteristics of the code-switched word. In addition, the finding that a contrastive effect occurs across all paradigms used to date, but that an assimilative effect occurs in only some paradigms, suggests that these two context effects may arise at different stages of processing.
