Abstract

A computer-implemented method for predicting, diagnosing and/or treating reading deficit in a human being is disclosed. The method includes generating a set of tonal stimuli, which includes at least a first tonal stimulus and a second tonal stimulus. The first tonal stimulus is separated from the second tonal stimulus by an interval. The computer-implemented method further includes providing the set of tonal stimuli to the human being and receiving a response from the human being. The response from the human being indicates a perception by the human being pertaining to the set of tonal stimuli. Further, the computer-implemented method includes ascertaining a first parameter pertaining to the set of tonal stimuli at which the response is inaccurate. The first parameter is one of a frequency parameter and a time parameter. The first parameter indicates that the human is susceptible to the reading deficit if the first parameter is above a predefined parameter value.

Claims

1. A computer-implemented method for predicting reading deficit in a human being based on acoustic measurements, comprising:

(a) generating a first tonal stimulus having a first frequency;

(b) generating a second tonal stimulus having a second frequency;

(c) providing said first tonal stimulus to said human being;

(d) providing said second tonal stimulus to said human being;

(e) receiving a response from said human being, said response having at least two response values, a first response value of said two response values indicating a first perception by said human being that said first tonal stimulus equals said second tonal stimulus, said second response value of said two response values indicating a second perception of said human being that said first tonal stimulus differs from said second tonal stimulus; and

(f) ascertaining a frequency difference at which said response becomes inaccurate, said frequency difference representing a difference between said first frequency and said second frequency, said frequency difference indicating said human being susceptible to said reading deficit if said frequency difference is above a predefined value.

2. The computer-implemented method of claim 1, further comprising:

modifying at least one of said first frequency and said second frequency to reduce said frequency difference if said response is accurate, and

repeating steps (a) through (f).

3. The computer-implemented method of claim 2, further comprising:

modifying at least one of said first frequency and said second frequency to increase said frequency difference if said response is inaccurate, and

repeating steps a through f.

4. The computer-implemented method of claim 1, wherein said human being is of a pre-reading age.

5. A computer-implemented method for predicting reading deficit in a human being, comprising:

(a) generating a set of tonal stimuli, including at least a first tonal stimulus and a second tonal stimulus, said first tonal stimulus being separated from said second tonal stimulus by an interval;

(b) providing said set of tonal stimuli to said human being;

(c) receiving a response from said human being, said response from said human being indicating a perception by said human being pertaining to said set of tonal stimuli;

(d) ascertaining a first parameter pertaining to said set of tonal stimuli at which said response is inaccurate, said first parameter being one of a frequency parameter and a time parameter, said first parameter indicating said human being susceptible to said reading deficit if said first parameter is above a predefined parameter value.

6. The computer-implemented method of claim 5 further comprising:

modifying one of said first tonal stimulus, said second tonal stimulus, and said interval if said response is accurate; and

repeating steps (a) through (d).

7. The computer-implemented method of claim 6 wherein said modifying comprises modifying at least one of a first frequency of said first tonal stimulus and a second frequency of said second tonal stimulus to reduce a difference between said first frequency and said second frequency, said first parameter representing said frequency difference and said predefined parameter value representing a predefined frequency value.

8. The computer-implemented method of claim 7 wherein said predefined frequency value is above about 50 Hertz.

9. The computer-implemented method of claim 7 wherein said set of tonal stimuli is independent of whether said human being is fluent in a given language.

10. The computer-implemented method of claim 7 wherein said human being is a pre-reading child.

11. The computer-implemented method of claim 6 wherein said modifying comprises reducing said interval, said first parameter representing said interval and said predefined parameter value representing a predefined time period.

12. The computer-implemented method of claim 11 wherein said predefined time period is about 100 milliseconds.

13. The computer-implemented method of claim 12 wherein said human being is a pre-reading child.

14. The computer-implemented method of claim 5 wherein said set of tonal stimuli is independent of whether said human being is fluent in a given language.

15. The computer-implemented method of claim 5 wherein said human being is a pre-reading child.

16. The computer-implemented method of claim 5 wherein said set of tonal stimuli further including a first masking sound and a second masking sound, said first masking sound being separated from said first tonal stimulus by a first time gap, said second masking sound being separated from said second tonal stimulus by a second time gap, said method further comprising:

reducing at least one of said first time gap and said second time gap; and

repeating steps (a) through (d).
