a processor, the processor presenting to a subject one or more statements or questions, as part of a credibility assessment test, prompting a response from the subject, wherein the one or more statements or questions presented by the processor includes a topic phrase and a declaration phrase;
an eye tracking device connected to the processor comprising:
an infrared camera configured to track one or more oculomotor activities of the subject during the credibility assessment test;
an audio output device in electronic communication with the processor configured to transmit the one or more statements or questions as sound to the subject;
a display screen connected to the processor presenting to the subject one or more images during the presentation of the one or more statements or questions, wherein at least a portion of the one or more images comprises a neutral image;
wherein the neutral image is an icon serving as a focal point for the subject;
wherein the infrared camera measures the one or more oculomotor activities when the neutral image is displayed and the subject observes the neutral image, and wherein the audio output device transmits the one or more statements or questions while the subject observes the neutral image;
wherein the processor analyzes the response received from the subject and compares the response to an expected response;
