5.3.4.2 Procedure for the Pre-test measures

British Picture Vocabulary Scale

In each trial the child was presented with plates which presented four pictures (the picture of
the target word, a semantic foil, a phonological foil and an irrelevant foil). The children were
asked to play a “word game”, which in fact was the administration of the BPVS. In that game
they had to point to one out of four pictures to indicate the word spoken by the experimenter
(e.g. Can you show me the x ?”). The test took a maximum of five minutes.

Target and control vocabulary pre-test

Each child was told that he∕she was going to play a game with the puppet. Then the puppet
asked the child “What do you think this is 'N (pointing at the target words).

Test of Non-word Repetition: A test of phonological working memory

The test contains 40 non-words, each of which is presented on the accompanying audio
cassette tape. The child listens to each non-word and then is required to attempt to repeat it
immediately, in the silent interval that follows the spoken presentation of the word on the
tape. The experimenter introduced the test by saying:

1. ⁱⁱIwould Hkeyou to help me. When I switch on this cassette recorder in a minute (point
to recorder), you will hear a funny made-up word. I would like you to say the funny word
back to me as soon as you have heard it. So, if the made-up word you heard was “noop ”, you
should say “noop” back to me. Let’s try that now, shall we I

2. “Voop”(child attempted repetition). If repetition attempt was incorrect, the experimenter
said:

3. “That was a good try, but it wasn ^,t quite right. Let’s try again ”. The procedure described
in 2 was repeated until a satisfactory repetition attempt was made by the child to this.

4. “ Very good. Now, let ^,s switch the tape on and hear some more made up words ”.

The experimenter asked the child “are you ready?” and then switches on the cassette
recorder.

The tape began as follows: ⁱⁱHello. In a few seconds you will hear a funny made-up word.
Please say the word aloud yourself as soon as you hear it ” Now here ^,s another one. Repeat
