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.
