Abstract

Provided are methods and tools for enhancing cognition in an individual. The methods involve presenting to the individual multiple sets of stimuli. Each set of the multiple set contains two or more stimuli and at least one set of the multiple sets contains a target stimulus. The method then receives an input from the individual, and informs the individual as to whether the input is a correct response. The methods encompass iterations of stimuli presentation, receiving of the input, and lastly, generation of feedback to the individual until the individual learns and retains what the target stimulus is.

First claim

What is claimed is:

1. A method of training for improving an individual's ability to suppress irrelevant stimuli, comprising:
executing instructions using a computer system to present to said individual via an output device multiple sets of auditory stimuli at an inter-stimulus interval of 600 milliseconds or less, wherein:
each of the multiple sets of stimuli comprises three or more auditory stimuli,
at least one set of said multiple sets of stimuli comprises a target auditory stimulus and an irrelevant auditory stimulus,
at least one set of said multiple sets of stimuli does not comprise the target auditory stimulus;
the irrelevant auditory stimulus differs in at least one or more acoustic properties from the target auditory stimulus, and
prior to presentation of a set of stimuli comprising the target auditory stimulus and an irrelevant auditory stimulus for the first time to said individual, said individual has not been informed of said target auditory stimulus or its properties;

receiving an input electronically from said individual in response to the presentation of at least one set of said multiple sets of stimuli, wherein:
the input requires a physical action by the individual, and
an input in response to a set of stimuli comprising the target auditory stimulus is a correct input; and

executing instructions to generate an output to inform said individual as to whether said input is correct.

2. The method of claim 1 , comprising repeating:
said executing instructions to present said multiple sets of stimuli,
said receiving step, and
said executing instructions to generate an output,
as a cycle and repeating said cycle with a selected time interval in between cycle.

3. A non-transitory computer-readable storage medium, comprising instructions executable by at least one processing device that, when executed, cause the processing device to:
(a) present to an individual via an output device multiple sets of auditory stimuli at an inter-stimulus interval of 600 milliseconds or less, wherein:
each of the multiple sets of stimuli comprises three or more auditory stimuli,
at least one set of said multiple sets of stimuli comprises a target auditory stimulus and an irrelevant auditory stimulus,
at least one set of said multiple sets of stimuli does not comprise the target auditory stimulus;
the irrelevant auditory stimulus differs in at least one or more acoustic properties from the target auditory stimulus and
prior to presentation of a set of stimuli comprising the target auditory stimulus and an irrelevant auditory stimulus for the first time to said individual, said individual has not been informed of said target auditory stimulus or its properties;

(b) receive an input electronically from said individual in response to the presentation of at least one set of said multiple sets of stimuli, wherein:
the input requires a physical action by the individual, and
an input in response to a set of stimuli comprising the target auditory stimulus is a correct input;

(c) determine whether said input is a correct input; and
(d) inform said individual by auditory or visual feedback as to whether said input is correct.

4. The non-transitory computer-readable storage medium of claim 3 , further comprising instructions executable by at least one processing device that, when executed, cause the processing device to repeat said presenting, said receiving, and said informing, wherein said target auditory stimulus is presented at least two times to said individual.

5. The non-transitory computer-readable storage medium of claim 4 , further comprising instructions executable by at least one processing device that, when executed, cause the processing device to determine a percentage of correct inputs from said individual, wherein said repeating is terminated where the percentage of correct inputs is the same or greater than a selected threshold.

6. The non-transitory computer-readable storage medium of claim 4 , wherein said repeating is terminated after about 60 minutes.

7. The non-transitory computer-readable storage medium of claim 3 , wherein each of said multiple sets is a group of three auditory stimuli.

8. The non-transitory computer-readable storage medium of claim 3 , further comprising instructions executable by at least one processing device that, when executed, cause the processing device to determine a difficulty in discerning a target auditory stimulus, and increasing or decreasing the difficulty based on said input.

9. The non-transitory computer-readable storage medium of claim 3 , wherein there are two or more different target auditory stimuli in the multiple sets.

10. The non-transitory computer-readable storage medium of claim 3 , further comprising instructions executable by at least one processing device that, when executed, cause the processing device to generate an output.

11. The non-transitory computer-readable storage medium of claim 10 , wherein said output is a reward.

12. The non-transitory computer-readable storage medium of claim 10 , wherein said output is a penalty.

13. The non-transitory computer-readable storage medium of claim 3 , wherein said target auditory stimulus differs from said irrelevant auditory stimuli in frequency, loudness, or timbre.

14. The method of claim 1 , wherein the target auditory stimulus of the multiple sets of stimuli is the same.

15. The method of claim 14 , wherein each of the multiple sets of auditory stimuli comprise two or more irrelevant auditory stimuli, which irrelevant auditory stimuli differ from each other.

16. The non-transitory computer-readable storage medium of claim 3 , wherein the target auditory stimulus of the multiple sets of stimuli is the same.

17. The non-transitory computer-readable storage medium of claim 16 , wherein each of the multiple sets of auditory stimuli comprise two or more irrelevant auditory stimuli, which irrelevant auditory stimuli differ from each other.

18. The method of claim 1 , comprising executing instructions using the computer system to repeat said executing instructions to present said multiple sets of stimuli, said receiving step, and said executing instructions to generate an output, wherein said target auditory stimulus is presented at least two times to said individual.

19. The method of claim 18 , comprising determining a percentage of correct inputs from said individual, wherein said repeating is terminated where the percentage of correct inputs is the same or greater than a selected threshold.

20. The method of claim 18 , wherein said repeating is terminated after about 60 minutes.

21. The method of claim 1 , wherein each of said multiple sets is a group of three auditory stimuli.

22. The method of claim 1 , further comprising executing instructions to increase or decrease a difficulty in discerning a target auditory stimulus based on said input.

23. The method of claim 22 , wherein if said input is correct, a difference between irrelevant stimuli and said target stimulus are decreased in a subsequent cycle, and if said input is incorrect, a difference between irrelevant stimuli and said target stimulus is increased or remains the same.

24. The method of claim 1 , wherein there are two or more different target auditory stimuli in the multiple sets.

25. The method of claim 1 , further comprising executing instructions to generate an output.

26. The method of claim 25 , whe
