Various communication studies have revealed the existence of a "preverbal" stage of communication consisting of centers within the brain that exists in an innate form or a form preprogrammed for future information acquired from the environment through experience (socialization). Such centers serve to prepare the individual for…

The sentence processing abilities of a conduction aphasic adult woman with a documented phonological coding deficit were investigated in tests of auditory and visual sentence comprehension of reversible active and passive sentences and spatial prepositions, sentence production through story completion and picture description, and repetition of…

Gives the results of a survey showing that the age factor, rather than the learning situation, is the predominant variant in learning the pronunciation of a second language. As Eric Lenneberg suggested, puberty may indeed be an important turning point in language learning ability. (TL)

The following papers are included: (1) "The Theoretical and Practical Relevance of Simple Codes in Second Language Acquisition" (Krashen); (2) "Talking to Foreigners versus Talking to Children: Similarities and Differences" (Freed); (3) "The Levertov Machine" (Stevick); (4) "Acquiring a Second Language when You're Not the Underdog" (Edelsky and…

The study summarized in this paper deals with the grammatical analysis of the spontaneous speech of approximately 150 children who are classified as mentally disabled; educable (I.Q. range 50-80). The performance of these mentally disadvantaged children is compared with the performance of 200 normally developing children by using a clinical…

This panel discussion seeks to determine the role of babbling and of nonlinguistic behavior in language acquisition. A central question is whether there is a continuity between babbling and speech. The paper presents the views that: the infant's ability to assimilate and adapt to his environment antedates the maturation of his visual and auditory…

Analysis of the questions asked by normal children suggests that there are cognitive stages of question development. Samples of spontaneous questions asked by normal children and linguistically deviant children were compared in this study in order to determine if linguistically deviant (aphasic) children suffer primarily from a syntactic…

Cognition, not to be confused with perception, reception, or stimulus detection, is defined as relationships of sensory experiences in single-loop matrices. The reticular system of the upper brain stem is centered upon as the likely locus of sensory filtering and modification that can modulate language usage. That is, higher cognitive functions…

Examines the language difficulties of an adult aphasic, particularly in the areas of reading and writing, in an attempt to fill a gap in the study of reading and writing pathology. (AM)

Reports on structural asymmetrics between the hemispheres which are found in the human brain. Auditory region and Sylvian Fissure asymmetry have also been observed in the fetus and in other primates. Describes research which has correlated asymmetries with hand preference, certain childhood learning disabilities and some dementing illnesses of…

In order to show the problem second language learners face when confronted with ambiguity, this article explores the linguistic and metalinguistic strategies used by adult Dutch learners of English. These learners possess the cognitive maturity and metalinguistic skills of native speakers but resemble--in knowledge of English-- children acquiring…

Proposes a theoretical information-processing-based neuropsychological model of writing and oral spelling which contains linguistic and motor components and which helps explain agraphia independently of other language disorders. Disruption of the phonological system is thought to cause phonological agraphia. Disruption of the lexical system is…

Emphasizes the importance of psycholinguistic research in enabling us to discover phenomena which will later be seen to have representations in the brain. In addition, the different ways a second language is learned and used, as well as the differences in the actual language structures themselves, will participate in determining brain organization…
