AT64 Portable Single-Channel SCR
 The Advanced Technology AT64 is an
easy-to-use, portable, single-channel SCR instrument with built-in data collection
capabilities. Skin conductance response (and its reciprocal GSR) has long been recognized
as a valid indicator of autonomic arousal. Now, the AT64 provides the MOST USEFUL SCR
information ever: quantified data on an individual's arousal level.
Clinical Applications
The AT64 SCR provides QUANTIFIED DATA for:
- Skin Conductance Activity, Level and Response (SCA, SCL & SCR).
- Testing the validity of self-reports. By displaying an individual's
SCR response to pertinent topics or visual stimuli, the AT64 SCR provides the hard data
for OBJECTIVE VERIFICATION.
- Early recognition of affective disorders through weekly monitoring of
patient baselines.
- Training appropriate emotional reactions and behavioral responses.
- Treating stress related disorders with patients who do not exhibit
elevated EMG readings or low peripheral skin temperature in response to stress.
- General relaxation training.
Superior Feedback
Audio: The AT64 SCR's built-in audio synthesizer
provides state-of-the-art audio feedback, clearly conveying information on the SIZE AND
DURATION of the SCR response. Audio feedback selections include:
- 1. Melodic piano tone,
- 2. Continuous tone and
- 3. Integrated clicks.
Visual: Visual feedback is provided via a numerical
display and/or a lightbar. The AT64's SCR Display button lets you select whether one
display is on, by itself, or both displays are on simultaneously.
Quality Information for Quality
Care
Like other Advanced Technology series instruments, the AT64 has
built-in data collection and analysis capabilities.
Data on the size and duration of each SCR response (indicating the
sensitivity of the topic) can be provided by the AT64 immediately following the response.
SUMMARY DATA (the mean, max., min., and SD) of all SCR
responses can be displayed by the AT64 at the end of the session.
