Iranian Child

This study investigates the development of early Persian vocabulary in the process of first language acquisition in case of an Iranian child at age 2. The child was named Melica in this paper and her speech was observed for the period of 6 months. The outcomes show that Melica could produce about 150 words and understand many more when she was 2 years old. Also she understood such meanings as “on”, “under”, and “in”. At that age, she mostly produced nouns, which represented more than half of her vocabulary. Observed for a period of six months, Melica showed a gradual development in word as well as in sentence production, though some discrepancies in the use of certain words, such as developmental errors and overextensions, were also reported.

Do So

This case study aims to discover the process of first language acquisition of a 4–year-old Iranian child. The focus of the research is on developmental errors the child has created in his language development, i.e. the words which are not correct. To do so, the researcher, during four months, observed and recorded the subject's produced strange words. The recording was done by two ways, Interval recording strategy and event sampling.Developmental errors or strange words are part of the learning process. These words are created due to different reasons. The research shows that during four months and in thirty three records, eleven strange words and expressions were produced. These eleven errors were investigated in this study in details. A table was presented by the researcher in which these errors were thoroughly described.

Learning Rates

First language acquisition is facilitated by several characteristics of infant-directed speech, but we know little about their relative contribution to learning different aspects of language. We investigated infant-directed speech effects on the acquisition of a linear artificial grammar in two experiments. We examined the effect of incremental presentation of strings (starting small) and prosody (comparing monotonous, arbitrary and phrase prosody). Presenting shorter strings before longer ones led to higher learning rates compared to random presentation. Prosody marking phrases had a similar effect, yet, prosody without marking syntactic units did not facilitate learning. These studies were the first to test the starting small effect with a linear artificial grammar, and also the first to investigate the combined effect of starting small and prosody. Our results suggest that starting small and prosody facilitate the extraction of regularities from artificial linguistic stimuli, indicating they may play an important role in natural language acquisition.

Striking Fact

The chapter argues that empirical studies of first-language acquisition lend support to the Wittgensteinian-Merleau-Pontian conception of language as against the prevailing conception that underwrites the method of cases in either its armchair or experimental version. It offers a non-representationalist model, inspired by the work of Michael Tomasello, for the acquisition of “knowledge,” with the aim of showing that we could fully account for the acquisition of this and other philosophically troublesome words without positing independently existing “items” to which these words refer. The chapter also aims at bringing out and underscoring the striking fact that, whereas many in contemporary analytic philosophy regard and present themselves as open and attentive to empirical science, they have often relied on a conception of language that has been supported by no empirical evidence.
