Question 2

The definition of a word is:
 
  A. a collection of phonemes that obeys a language's phonotactic rules.
  B. an arbitrary symbol that refers to elements in the word.
  C. a sound that is used to communicate.
  D. the smallest unit of meaning in language.

Question 3

What do biologically and usage based theories of phonology focus on?
 
  A. Biologically based theories focus on the importance of computational constraints of phonotactics while usage based theories focus on how phonology is used in emerging literacy.
  B. Both biologically and usage based theories focus on the organization of the phonological system.
  C. Biologically based theories focus on the role of anatomical and physiological factors in development while usage based theories focus on the role of environmental input.
  D. Biologically based theories focus on the role of environmental input while usage based theories focus on the role of anatomical and physiological factors in development.

Question 4

Which best describes the relationship between phonological and lexical development?
 
  A. phonological development leads lexical development: children's first words are composed of sounds from within children's phonological inventory and children with larger inventories usually have larger vocabularies
  B. lexical development leads phonological development: as the size of children's lexicons gets larger, they develop more precise phonology in order to distinguish among the words.
  C. neither answer A nor B are true: phonological and lexical development operate wholly independently from each other.
  D. both answers A and B are true: the relationship between phonological and lexical development is an inter-dependent one.
