Abstract
A new speech development test was prepared for one-year-old infants. The test consists of three parts: test I, II, and III The overall test originally comprised a total of 98 test items (47 for Test I, 32 for Test II and 19 for Test III).
Test I (for pre-speech language)
§1 Situation of language
i) Differentiation of information to be communicated
ii) Comprehension of speech-related situation (Initiation of “signe”, and comprehension of objects and events by means of speech)
§2 Development of symbolizing function (Development and transformation of ability to handle and manipulate objects)
§3 Representing the function of language (First utterance, and acquisition of meaningful words after first utterance)
Test II (for speech comprehension)
Ability to name concrete objects, and to relate objects to their uses and functions; comprehension of words representing spatial concept such as quantity, number and dimensions, as well as words representing color or position.
Test III (for speech expression)
Ability to verbalize or name concrete objects, and to verbalize the conduct and state of a person.
For infants, language is an objective to be achieved, while for adults it is the mean of thinking and communicating. Despite this difference the scope of this test comprises two major aspects common to the language-related experience of infants and of adults: pragmatics and vocabulary.
