  Turkish speaking children's early lexicon in terms of noun/verb dominance

  A great number of research findings reveal that nouns are acquired earlier
  than verbs because basic level object categories are represented by nouns,
  leading to dominance of nouns over verbs. This noun-before-verb acquisition
  pattern is universal regardless of the language (Gentner, 1981, 1982; Au et
  al, 1994; Caselli et al, 1995).  However, some researchers are in
  disagreement with this claim and they propose that verbs can be acquired
  earlier than nouns as children are exposed to more verbs in the maternal
  input and some language characteristics such as word order and morphology
  can reinforce dominance of verbs over nouns (Choi & Gopnik, 1993, 1995;
  Tardif, 1993, 1996). This constitutes the other end of this controversial
  topic. Therefore, the arguments show two opposite ends: universal conceptual
  constraints versus language characteristics. 

                 The primacy of nouns or verbs have been studied in different
  languages, such as English, German, Korean and Chinese by using various data
  collection tools. However, this issue was not studied in Turkish by means of
  longitudinal data-frequency analysis. Leading Turkish researchers focused on
  that aspect but their analysis were different (Küntay & Slobin, 1996, 2001,
  2002; Ketrez & Aksu-Koç, 2003; Ketrez, 2004). That is why, this study mainly
  concentrated on Turkish speaking children's lexical development in terms of
  noun and verb frequencies. 

                 Another much debated issue is the role of the motherese. Choi
  (2000) states that "in various domains of language, there is a growing body
  of evidence that caregiver input influences children's early language".
  Tardiff, Shatz & Naigles (1997) compared the degree of saliency of nouns and
  verbs in caregivers' spontaneous speech in English, Chinese and Italian. As
  a result of this study, it was shown that Chinese caregivers provided verbs
  more frequently than English and Italian caregivers, and verbs are at the
  end of their utterances. In line with this argument, it is claimed that such
  language specific properties in the input may explain the early acquisition
  of verbs by children. Turkish is also a language in which verb is placed at
  the end of the clause and because of the rich inflectional system a single
  verb can stand for a sentence. Some elements (even the head in some some
  noun phrases) can be dropped in utterances; whereas, verbs cannot. This
  study also investigated the Turkish motherese in terms of this structural
  property. 

  The findings of the study indicated that the frequency of nouns in Turkish
  speaking children's early lexicon was not considerably higher than their
  verbs. Nouns became statistically dominant over verbs in a very limited
  number of observed times. The results of this study supported an important
  point regarding noun and verb acquisition pattern. In all children, verb
  acquisition was more progressive, whereas the nouns were context-dependent.
  In some children, towards the end of the data collection period, a higher
  verb frequency over nouns was seen.
