Product Number: HMS-500

This program is provided to allow the user to make changes in system parameters for each installed module of the Human Measurement System and to test the hardware and subject connections before beginning any of the procedures.  Sound level calibration for the Startle module is accomplished here as is the testing of the integrators used for EMG channels in all software modules.  System parameters such as the sensitivity and offset settings are determined and recorded, and values for the software filters for the ECG are entered in the Utilities module.  Other features allow for testing all channels of the A/D converter and testing the subject devices (video splitter, mouse splitter, finger shocker).

Product Number: HMS-400

Acquisition and extinction of a conditional response to an aversive stimulus, typically an electric shock delivered to two fingers of one hand, are studied in this procedure.  The user selects the images to be presented – any of four geometric figures in any of six colors – which will be designated as S+ (the stimulus presentation which does not end in aversive stimulation) and which as S- (which is followed by aversive stimulation), and the duration of the aversive stimulus.  The sequence in which the visual stimuli are presented and the number of stimulus exposures in the session are user-specified. The software controls the separate subject monitor and finger shocker while acquiring data for ECG, SCR, and EMG modalities.

Product Number: HMS-300

In this procedure, scripts are read to subjects and they are asked to imagine themselves in the situations described.  Baseline data are collected in the periods between scripts, and response data are acquired during the reading of the scripts, during the imagery periods immediately following the scripts, and during a recovery period.  Self-reports of various emotional responses to the scripts follow the recovery period.  Data include EMG, ECG, SCR and self-report scores; both scored and raw psychophysiological data may be saved.  Scripts are recorded as .wav files and are presented in a sequence which is user-determined.  All aspects of the exposure to the selected scripts are automated as is the subjects’ access to a monitor and mouse for self-reports.

Product Number: HMS-200

In the classic Stroop paradigm, a subject is presented with a task designed to affect reaction time.  For example, the stimulus may be the word “green” printed in red ink and the subject is required to respond to the ink color rather than the word itself.  In this variation of the classic procedure, the subject is presented with photographs on different colored backgrounds and is asked to respond to the background color.  Reaction time is measured as an index of any interference in processing time introduced by the subjects’ reaction to the content of the photographic image.  The software controls the separate monitor on which the subject views the images and records the responses from a four-button console on which the subject indicates the background color.  Both the latency of the response and the color choice are recorded.  The stimulus may, at the users’ discretion, be masked by a different image on some or all trials.  On masked trials, the stimulus is presented for a brief time and is then masked by another image.  The subject is instructed to respond to the first image only.  In addition to response data, the system collects psychophysiological data for EMG (one or two channels), ECG and SCR.

Product Number: HMS-100

The standard CI Human Startle System is a turnkey hardware/software package designed to facilitate protocol design, collecting & storing data and viewing subjects' responses both real time and delayed time. All data are readily exportable to any spreadsheet application.

During the protocol phase, the user selects which stimuli will be presented on each trial. Any trial may include a pure tone and/or white noise stimulus and either may appear in the pre-pulse or startle stimulus temporal position. Blank trials (i.e., trials during which neither stimulus is presented) may also be included. For tones, the user specifies the duration, the amplitude and the frequency. For white noise, the duration and amplitude are specified by the user.
