Abstract

The present invention provides a method and apparatus for screening infants at high risk for central auditory processing deficits and then remediating less efficient processing behaviorally using an adaptive training algorithm that gradually increases sensitivity to rapidly occurring stimuli streams.

First claim

The invention claimed is:

1. A system for screening information processing deficiencies or improving information processing in an infant comprising:
a processor operably connected to a sound-emitting device and an input device, wherein the processor is configured to:
generate a first sequence of auditory stimuli comprising at least one control stimulus having a plurality of control components and at least one test stimulus having a plurality of test components, wherein the at least one control stimulus differs from the at least one test stimulus by at least one of amplitude, frequency, pitch, and duration, the at least one control stimulus and the at least one test stimulus are administered within about 0.5 seconds to about 3 seconds of each other, and
receive from the input device an indication of one or more of the following: an initiation or modification of the first sequence of auditory stimuli, and a reinforcement stimulus in conjunction with the at least one test stimulus;
a recorder adapted to register a response of the infant to the at least one test stimulus or the at least one control stimulus, wherein the recorder is operably connected to the input device,
wherein the sound emitting device is configured to emit the first sequence of auditory stimuli,
wherein the processor is configured to modify a duration of a filled temporal interval or an unfilled temporal interval between the control or test components in the at least one control stimulus or the at least one test stimulus based on the response of the infant.

2. The system of claim 1 , further comprising a memory containing a plurality of sensory components, wherein the processor is further configured to combine or modify the sensory components to produce a plurality of sequences of auditory stimuli, and wherein the memory is operably connected to the processor.

3. The system of claim 2 , wherein the memory comprises the plurality of the sequences of auditory stimuli, and wherein the processor is further configured to transmit at least a second sequence of auditory stimuli to the sound-emitting device in response to receiving the response of the infant to the at least one test stimulus.

4. The system of claim 2 , wherein the memory comprises the plurality of the sequences of auditory stimuli, and wherein the processor is further configured to transmit at least a second sequence of auditory stimuli that is identical to the first sequence of auditory stimuli to the sound-emitting device in response to receiving the response of the infant to the at least one test stimulus.

5. The system of claim 4 , wherein the processor is further configured to initiate at least the second sequence of auditory stimuli based on an incorrect response of the infant.

6. The system of claim 2 , wherein the processor is further configured to transmit at least a second sequence of auditory stimuli to the sound-emitting device in response to receiving the response of the infant to the at least one test stimulus, wherein at least the second sequence of auditory stimuli is different from the first sequence of auditory stimuli, wherein at least the second sequence of auditory stimuli comprises at least one control stimulus and at least one additional test stimulus, and wherein the at least one additional test stimulus differs from at least one test stimulus by at least one characteristic selected from the group consisting of frequency, duration, pitch and amplitude.

7. The system of claim 2 , wherein the processor is further configured to transmit at least a second sequence of auditory stimuli to the sound-emitting device in response to receiving the response of the infant to the at least one test stimulus, wherein at least the second sequence of auditory stimuli is different from the first sequence of auditory stimuli, wherein at least the second sequence of auditory stimuli comprises at least one control stimulus and at least one additional test stimulus, wherein the at least one additional test stimulus differs from at least one test stimulus by at least one characteristic selected from the group consisting of frequency, duration, pitch and amplitude, and wherein a difference between the at least one control stimulus of at least the second sequence of auditory stimuli and the at least one additional test stimulus of at least the second sequence of auditory stimuli is larger than a difference between the at least one control stimulus of the first sequence of auditory stimuli and the at least one test stimulus of the first sequence of auditory stimuli.

8. The system of claim 1 , wherein:
the sound-emitting device is further configured to emit a sequence of auditory stimuli comprising at least one control stimulus having a plurality of control components and at least one test stimulus having a plurality of test components, wherein a number of control components in the at least one control stimulus is identical to a number of test components in the at least one test stimulus,
the processor is further configured to modify a duration of a filled temporal interval or an unfilled temporal interval between the control or test components in the at least one control stimulus or the at least one test stimulus based on the response of the infant such that the duration of the filled or unfilled temporal interval in the at least one control stimulus is identical to the duration of the filled or unfilled temporal interval in the at least one test stimulus.

9. A toy for screening information processing deficiencies or improving information processing in an infant comprising:
a processor operably connected to a sound-emitting device and an input device, wherein the processor is configured to:
generate a sequence of auditory stimuli comprising at least one control stimulus having a plurality of control components and at least one test stimulus having a plurality of test components, wherein the at least one control stimulus differs from the at least one test stimulus by at least one of amplitude, frequency, pitch, and duration, the at least one control stimulus and the at least one test stimulus are administered within about 0.5 seconds to about 3 seconds of each other, and
receive from the input device an indication of one or more of the following: an initiation or modification of the sequence of auditory stimuli, and a reinforcement stimulus in conjunction with the at least one test stimulus;

a recorder adapted to register a response of the infant to the at least one test stimulus or the at least one control stimulus, wherein the recorder is operably connected to the input device,
wherein the sound emitting device is configured to emit the sequence of auditory stimuli,
wherein the processor is configured to modify a duration of a filled temporal interval or an unfilled temporal interval between the control or test components in the at least one control stimulus or the at least one test stimulus based on the response of the infant.

10. A system for screening information processing deficiencies or improving information processing in an infant comprising:
a processor configured to generate a sequence of auditory stimuli comprising at least one control stimulus having a plurality of control components and at least one test stimulus having a plurality of test components, wherein the at least one control stimulus differs from the at least one test stimulus by at least one of amplitude, frequency, pitch, and duration, the at least one control stimulus and the at least one test stimulus are administered within about 0.5 seconds to about 3 seconds of each other;
one or more speakers in communication with the processor, wherein the one or more speakers are configured to emit the sequence of auditory stimuli
