Further background information and hints for lateralization settings
Lateral width ...
Limitation - AlphaTrainer HOME:
You can only adjust the lateral width with the AlphaTrainer Professional.
•
Some clients may feel slightly uneasy when the lateral width is set to 180° (when experiencing latera-
lization for the
fi
rst time). Adjust this setting only with clients that express such a discomfort. With each
training session you then increase the lateral width until reaching 180°.
•
This function allows you to analyze how well your clients can direct their attention towards the lateral
movement and how well they can concentrate on their respective reading task: Slightly adjust the set-
tings for the lateral width. If the client responds to this adjustment and gets distracted from the reading
task, the level of concentration is not at its best.
•
In return, applying very small values for the lateral width allows you to analyze how well the spatial
hearing of your client works.
Auditory-visual synchronization ...
•
As soon as you change one of the settings for lateralization (hold times, transfer times) the synchro-
nicity is no longer in place.
•
This function should only be applied with clients that show dif
fi
culties using the LCD shutter glasses
in parallel to the auditory stimulation. After some training sessions you should reach a level of compe-
tence in your client that allows for continuous non-synchronized training
Employment and settings for the LCD shutter glasses ...
Limitation - AlphaTrainer HOME:
With the AlphaTrainer HOME the shutter glasses can be used. With the AlphaTrainer Professional,
the level of darkness intensity is scalable.
• Note:
The client should continue to wear his regular glasses underneath the LCD shutter glasses.
•
Use the LCD shutter glasses only in a later stage of the training. The client should already be accusto-
med to the auditory training modes.
Exception:
For clients with visual perception problems, the LCD shutter glasses should be used
at starting at an early stage of training.
•
The level of intensity for the LCD glasses should usually be set to 100%. If the client struggles with the
reading process when applying the LCD glasses, temporarily reduce the level of darkening intensity.
Rebuild it to 100% within a few weeks of training.
• Important:
As with the auditory settings, ensure that you choose values comfortable for your client in
order to keep him motivated for the training.
Lateralization for the coach ...
•
If you drove through lateral training daily in several training units with clients, have possibly the need
to hear the language normally. For this purpose you can use the non-lateralization adapter. This sup-
presses the movement at the jack headset-phone, at which he is attached. The lateralization to client
headphones remains unimpaired of it.
•
In order to use the adapter, you proceed as follows:
1. Pull the plug at the headphone cable out of the AlphaTrainer.
2. Put the non-lateralization plug into the device socket.
3. Put the plug at the headphone cable into the socket of the non-lateralization plug.
