Well, youngsters do this.
We all do this because we don't always hear 100% of the time all the clarity.
So we figure out what the word could be.
And, again, that's a closed technique.
And so we test that ability.
We test the child's discrimination in quiet and in noise for speech.
And we also test the child's ability to take in words that may be staggered, words that are rapid.
or time-compressed sentences.
We also test nonverbally the child's ability to detect when one beep becomes two beeps because it is split by a narrow gap anywhere from one millisecond to 40 milliseconds.
Most youngsters certainly can hear a gap between two tones of 20 to 40 milliseconds, but those who have trouble may have trouble hearing the gap and certainly not recognizing a gap that's lower than 20 milliseconds.
So that tells us about their timing, their ability to take advantage of small increments in time, duration.
We also can test pattern and pitch pattern discrimination and duration of pattern discrimination.
That is, it tells us about can the individual recognize differences in pitch or differences in timing.
duration, timing, long and short tones, and that's a nonverbal task.
