## Abstract

A method of training a subject to improve anticipatory timing includes presenting the subject with multiple sequences of stimuli, receiving sensor signals associated with responses by the subject to the stimuli, and recording response times in accordance with the sensor signals, wherein the recorded response times are associated with the responses by the subject to the multiple sequences of stimuli, and wherein the response times have an associated distribution. The method further includes analyzing the distribution of response times for the subject to determine variability in anticipatory timing of the subject with respect to the stimuli, and generating a subject feedback signal corresponding to a result of the analyzing so as to train the subject to improve anticipatory timing of the subject.

## Claims

### Claim 1

A method of training a subject to improve anticipatory timing, comprising:
performing a sequence of operations, including:
using a display device, visually presenting to the subject multiple sequences of visual stimuli;
receiving, from a sensor, sensor signals associated with responses by the subject to the stimuli;
recording response times in accordance with the sensor signals, wherein the recorded response times are associated with the responses by the subject to the multiple sequences of stimuli, and wherein the response times have an associated distribution;
analyzing the distribution of response times for the subject to determine variability in anticipatory timing of the subject with respect to the stimuli; and
presenting a subject feedback signal to the subject, the feedback signal corresponding to a result of the analyzing, and repeating the sequence of operations so as to train the subject to improve anticipatory timing and reduce variability of the subject responses with respect to the stimuli.

### Claim 2 (depends on 1)

The method of claim 1, wherein the analyzing includes comparing the anticipatory timing of the subject with normative data and classifying the anticipatory timing of the subject, including the variability of the anticipatory timing of the subject, as normal or abnormal in accordance with a result of the analyzing.

### Claim 3 (depends on 1)

The method of claim 1, including repeating the presenting, receiving, recording, analyzing and generating multiple times so as to generate a sequence of subject feedback signals, thereby enabling the subject to improve responses to the visual stimuli in accordance with the subject feedback signals.

### Claim 4 (depends on 1)

The method of claim 1, wherein the visual stimuli consists of a smoothly moving object, repeatedly moving over a tracking path and the sensor signals are signals derived from video signals monitoring eye movements of the subject; and wherein the determined variability corresponds to how consistently eye movements of the subject visually track movement of the object.

### Claim 5 (depends on 4)

The method of claim 4, wherein the video signals are generated by a camera operating at a picture update rate of at least 200 Hertz.

### Claim 6 (depends on 1)

The method of claim 1, wherein the sensor signals are associated with a manual action by the subject.

### Claim 7 (depends on 1)

The method of claim 1, wherein presenting the subject feedback signal is responsive repeated analysis of the subject's variability in anticipatory timing with respect to the visual stimuli.

### Claim 8 (depends on 1)

The method of claim 1, wherein presenting the subject feedback signal includes presenting the subject feedback signal so as to train the subject to reduce the subject's variability in anticipatory timing with respect to the stimuli.
