Claim 6

Independent Claim 74 words

A method of conditioning a desired psychological response in a subject comprising the steps of: a) monitoring at least one of the subject's electrophysiological parameters indicative of his psychological response; and b) presenting to the subject a sequence of versions of an audio-visual scene, said versions exhibiting varying audio and visual reality wherein said audio and visual reality are increased as said monitored parameters indicate that the subject's psychological response has become more desirable.

Claim 7

Independent Claim 74 words

A method of conditioning a desired psychological response in a subject comprising the steps of: a) monitoring at least one of the subject's electrophysiological parameters indicative of his psychological response; and b) presenting to the subject a sequence of versions of an audio-visual scene, said versions exhibiting varying audio and visual reality wherein said audio and visual reality are increased as said monitored parameters indicate that the subject's psychological response has become more desirable.

Claim 8

Dependent Claim 39 words

The method of claim 5 further comprising the step of: c) repeating steps a and b on distinct occasions until said monitored parameters indicate that the subject has become conditioned to exhibit the desired response to said audio-visual scene.

Claim 9

Dependent Claim 64 words

The method of claim 6 wherein the desired psychological state is relaxation and further comprising the step of: d) teaching the subject to perform a motor skill while presenting to the subject said audio-visual scene at a time subsequent to the conditioning, whereby the subject's ability to learn said skill is enhanced by the subject having been conditioned to enter said desired psychological state.

Claim 10

Dependent Claim 64 words

The method of claim 6 wherein the desired psychological state is relaxation and further comprising the steps of: d) presenting the subject with material to be learned while presenting to the subject said audio-visual scene at a time subsequent to the conditioning, whereby the subject's ability to learn said material is enhanced by the subject having been conditioned to enter said desired psychological state.

Claim 11

Dependent Claim 17 words

The method of claim 5 wherein said audio and visual reality are increased occurs in discrete steps.

Claim 12

Dependent Claim 43 words

The method of claim 5 wherein at step b, said increase is in response to a weighted combination of said parameters and said audio and visual reality are decreased as said weighted combination indicates that the subject's psychological response has become less desirable.

Claim 13

Dependent Claim 18 words

The method of claim 10 wherein said increase and said decrease in said reality occurs in discrete steps.

Claim 14

Dependent Claim 55 words

The method of claim 5 wherein the desired psychological state is relaxation and further comprising the step of: c) teaching the subject to perform a motor skill when the subject's psychological response has become more desirable, whereby the subject's ability to learn said skill is enhanced by the subject's being in said desired psychological state.

Claim 15

Dependent Claim 55 words

The method of claim 5 wherein the desired psychological state is relaxation and further comprising the step of: c) presenting the subject with material to be learned when the subject's psychological response has become more desirable, whereby the subject's ability to learn said material is enhanced by the subject's being in said desired psychological state.

Claim 16

Independent Claim 19 words

The method of claims 12, 13, 7 or 8 wherein said improvement in said reality occurs in discrete steps.

Claim 17

Independent Claim 111 words

An apparatus for conditioning a desired psychological response in a subject comprising: (a) means for monitoring at least one of the subject's electrophysiological parameters indicative of his psychological response; (b) means for determining from the values of said monitored parameters when the subject's psychological response has become more desirable; (c) means for presenting to the subject a sequence of versions of an audio-visual scene, said versions exhibiting varying audio and visual reality; and (d) means for controlling said presenting of said sequence so as to display to the subject a scene of increased audio and visual reality when said monitored parameters indicate that the subject's psychological response has become more desirable.

Claim 18

Independent Claim 111 words

An apparatus for conditioning a desired psychological response in a subject comprising: (a) means for monitoring at least one of the subject's electrophysiological parameters indicative of his psychological response; (b) means for determining from the values of said monitored parameters when the subject's psychological response has become more desirable; (c) means for presenting to the subject a sequence of versions of an audio-visual scene, said versions exhibiting varying audio and visual reality; and (d) means for controlling said presenting of said sequence so as to display to the subject a scene of increased audio and visual reality when said monitored parameters indicate that the subject's psychological response has become more desirable.

Claim 19

Dependent Claim 45 words

The apparatus of claim 15 wherein said determining means measures a weighted combination of said monitored parameters and said controlling means also displays a scene of decreased audio and visual reality when said monitored parameters indicate that the subject's psychological response has become less desirable.

Claim 20

Dependent Claim 21 words

The apparatus of claim 16, wherein said presenting means further comprises means for increasing and decreasing said reality in discrete steps.

Claim 21

Claim 22

Independent Claim 105 words

An apparatus for mediating a biofeedback session with a subject, at least one of whose electrophysiological parameters is being measured, comprising: a) means for receiving signals indicative of the measurements of the parameters; b) audio-visual storage medium comprising at least one cluster, wherein each of said clusters comprises a plurality of physically contiguous audio-visual sequences progressively degraded in reality; c) playback means for retrieving said sequences from said medium; d) control mean for receiving said signals and controlling an order of retrieval of said sequences based on said signals; and e) audio-visual output means whereby the subject is able to view an hear said sequences.

Dependent Claim 21 words

The apparatus of claim 18 wherein said control means is a digital computer, said digital computer further comprising a computer program.

Claim 24

Dependent Claim 95 words

The apparatus of claim 19 wherein said computer program is a computer program for controlling a biofeedback session in which at least one of said signals is acquired from a subject and version of an audio-visual scene are exhibited to the subject, said versions having varying levels of reality, said computer program comprising: a) means for selecting a combination of said signals to be monitored; b) means for computing a weighted average of said monitored signals; c) means for repeatedly selecting one of said versions for exhibition to the subject based upon said weighted average.
