An interactive automatic system and technique for measuring and training of mental ability. In the illustrative embodiment, the invention is implemented on a computer which automatically presents a variety of visual and auditory stimuli. The system then measures reaction to the stimuli, adjusts certain stimulus parameters, and provides scores in response thereto. The scores are tabulated and displayed for analysis. In particular embodiments, the invention tests for physical reaction time, perceptual awareness thresholds, attention level, speed, efficiency and capacity of information processing by the brain and elementary cognitive processes, including memory, memory access and decision-making speed. The invention measures, identifies and quantifies noise in the subject's brain and elementary cognitive processing system, and the information exchange rate between the subject's left and right brain hemispheres. The inventive system compiles a history of the test scores, renders an overall performance rating, and delivers comments based on the subject scores. The complexity of the tests are adjusted based on the scores to optimally challenge cognitive capacities, thereby rendering more accurate evaluations of cognitive capacity, and optimizing learning of desired improvements in perceptual, physical and mental response speeds and efficiencies.

A multi-media method and system performs psychological assessment of an individual for suitability for particular jobs, whereby the individual is shown and provided with discrete visual and auditory stimuli on a multi-media computer screen, so that the individual's responses can be monitored in conjunction with physiological responses received by biofeedback sensors. The computer tallies the test subject's recorded responses. Virtual work environments are optionally displayed, to enable the tested individual to simulate a real work environment. Unlike other job evaluation systems, the system evaluates a job candidate's ability to maintain task focus under pressure. It directly measures performance under pressure, rather than only inferring potential performance based upon selective input from a job candidate.

An apparatus and method for presenting high-quality auditory stimuli, receiving patient communication and providing noise cancellation within the environment of magnetic resonance imaging (“MRI”) equipment. A microphone is positioned in a noise attenuated channel for recording of the patient's voice. A microphone is disposed outside of a noise attenuated channel to directly record the sounds of MRI equipment during its operation. The signals generated by the microphones are employed to reduce the output of noise generated by MRI equipment.

A method and apparatus for utilizing the benefits of encoded signal transmission and reception to enhance the performance of medical testing devices (100) adapted to evoke and measure biological response signals such as auditory evoked potentials (AEP), and the auditory brainstem response (ABR) signals in particular. Auditory stimuli, such as clicks, are presented to the ear of a human patient, in a predetermined encoded sequence, resulting in the generation of auditory responses and bio-electric response signals in the human patient. These response signals from the patient are acquired and observed, and are processed according to the predetermined encoded sequence in which the auditory stimuli were presented to the patient's ear in order to extract the desired auditory evoked potential signals or ABR signals.

An automated screener device screens hearing, schedules an appointment, and produces a physician order upon a patient failure of the screening. The screener includes a computer with a touch screen to facilitate responses to a short questionnaire and to auditory stimuli. A set of noise cancelling head phones are used by the patient during the hearing screening. The computer has an associated printer which prints test results. A failed screening test causes production of a printed report having signature line for physician referral. An appointment schedule appears on the touch screen immediately allowing the patient to schedule an appointment with an area audiologist. The method of operation is also disclosed.

A vibroacoustic system includes a shell having a plurality of transducers mounted in an energy transmitting relation thereto. The transducers receive input signals having distinct wave characteristics and drive the shell to simultaneously produce both a vibratory experience effected by a tactile stimulus and an auditory experience effected by an aural stimulus.

Methods and devices (10) generate an exogenous natural speech signal (10s) as an auditory stimulus to a user to enhance the fluency of persons who stutter. The natural speech signal (10s) is independent of the contemporaneous speech production of the stutterer and is provided by a voice gesture and can be a prolonged or sustained voice gesture sound such as a simple vowel, or consonant, or vowel trains and the like. The second speech signal (10s) can be transmitted in advance of a speaking event or speech production of the stutterer and/or concurrently with a speaking event, either intermittently or continuous during the speaking event. The devices (10) of the instant invention are configured to provide the voice based speech signal (10s) such that it is audible to the user and does not require feedback of the user s own speech allowing the user to speak at a substantially normal pace with enhanced fluency. The device (10) and methods can relay the signal (10s) based on a manual activation or automatically based on a detection of speech or a stuttering event on the part of the user.

The invention discloses a P300-based audio-visual dual-channel competition mechanism brain-computer interface method. The method comprises the following steps: setting a first normal form as an audio-visual interference normal form, and displaying visual stimulation as monosyllable letters in the center of a screen in different colors; setting a second normal form as an audio-visual irrelevant normal form, enabling the auditory stimulation to be still monosyllable letters which are the same as those of the first normal form and visual stimulation to be six geometric figures which are differentin shape and color, and enabling the patterns to have no correlation with the letters of the auditory stimulation; setting different stimulation time intervals, stimulation lengths, stimulation presentation sequences and attention modulation modes; and collecting electroencephalogram signals through 64-lead electroencephalogram electrode caps, comparing tested electroencephalogram signals under different tasks, and analyzing quantitative and positioning representation of the competitive relation between vision and auditory senses. To be specific, the auditory stimulation is the same monosyllable letters and is output in two channels of an in-ear earphone; and the sound stimulation is set to have the same semantics as the visual stimulation and have the same visual and auditory stimulationtime.

Hair cells are exquisitely sensitive to auditory stimuli, but also to damage from a variety of sources including noise trauma and ototoxic drugs. Mammals cannot regenerate cochlear hair cells, while non-mammalian vertebrates exhibit robust regenerative capacity. To allow for the effective examination of this process disclosed herein is a design and method of utilizing a device capable of inducing acoustic trauma in the larval lateral line. The device uses ultrasonic transducers to induce cavitation wherein microbubbles form in the fluid medium inside the container. These bubbles oscillate and then implode, sending shockwaves into the fluid inside the well-plate containing the fish. The device emits a broadband signal with peak sound energy in the low-frequency range below 200 Hz, consistent with the response range of the larval lateral line.
