Electroencephalography (EEG) Designs

*** THIS PRODUCT HAS BEEN WITHDRAWN FROM SALE. ***

A set of 8 designs offering both continuous and discrete feedback.

Design features

• Dual screen designs (therapist and client) included.
• Discrete feedback with refractory periods: after a point has been scored (the signal has crossed a threshold) there is a brief period in which subsequent threshold crosses are not rewarded. Leaders in the field recommend this as offering the best conditions for learning.
• Use of training periods: a button begins a timed period of training, at the end of which the client's feedback is switched off, allowing rest, but the trainer can continue to monitor the signal, change thresholds etc. The length of training period can be easily changed. At the end of the session the overall pattern can be clearly visualised - see trend below. The gain over each training period is calculated.

Graphical Feedback Features

• long term trend (20 min), showing training periods (green blocks in lower graph)
• 

DVD Feedback

DVD feedback follows a negative reinforcement paradigm: when the signal moves in the "wrong" direction, the picture quality degrades by either "greying out" or by shrinking. Sound quality is also degraded (using white noise). Conversely, when the signal moves in the "right" direction, the picture is unimpeded.

	1. Basic EEG Design In the basic design, the main training feedback is the bar graph to the right, with points score below. The trainee must lower the bar graph to score a point. This design has two channels of EEG.
	2. EEG DVD Design The area surrounding the DVD, normally black, flashes green when a point is scored, and the DVD picture becomes clear.
