Grass 7D Polygraph machine

Made in Massachusetts, United States of America, 1984.

The Grass 7D Polygraph machine was used by Macquarie University researchers in the 1980s and 90s for research into a learning process called Associative Learning, in which discrete ideas and precepts become linked to one another and associations are formed between stimuli and reactions. It was never used as a lie detector but was used to record skin conductance response (SCR), evoked cardiac response, reaction times (RT), respiratory response, and orienting response.

The unit is mounted on a trolley. The lower part of the trolley has a recess for storing the continuous-feed paper used for recording data. The middle section of the unit houses the printing apparatus. Above this is the control interface, consisting of six panels of control dials and switches. The second control panel features the inputs for the skin conductance meter and electrodes which are used to measure responses.
