Purpose: This study examines whether differences in acquisition exist among the inflectional constructions of number, gender, possessive pronouns, and tense. Moreover, the study investigates whether these inflectional patterns develop with age. Method: The participants were 1,020 Arabic-speaking kindergartners from K2 and K3. Children were…

This study investigated the acquisition of word-patterns and roots in the nominal system of the spoken language of Palestinian Arabic (PA) and its distance from Standard Arabic (StA). It described, analyzed, and quantified the nominal system (roots and word-patterns) as reflected in the language corpus of Palestinian-Arab kindergarteners 3 to 6…

Given the rich bound morphology of Spoken Arabic, an attempt was made here to construct a developmental measure corresponding to the mean length utterance (MLU) in English and to morpheme-per-utterance (MPU) in Hebrew. The adaptation to Arabic resulted in a new measurement termed Arabic-MPU, that was experimentally tested on a sample of 98…

The acquisition of German plurals has been the focus of controversy in the last decade. In this paper we claim that degree of productivity (i.e. the capacity of nouns to form potential plurals) plays a key role in determining pace of acquisition. A plural elicitation task was administered to 84 Viennese German-speaking children aged 2;6 to 6;0.…

The present research examined how 3- and 5-year-old Japanese children map novel nouns and verbs onto dynamic action events and generalize them to new instances. Studies 1 to 3 demonstrated that although both 3- and 5-year-olds were able to map novel nouns onto novel objects, only 5-year-olds could generalize verbs solely on the basis of the…
