Research: Linguistic Inquiry and Word Count (LIWC) Analysis to Detect Deception

In law enforcement, a number of techniques and devices have been employed through the years as investigative tools to help identify deception.  One technique which is not commonly in use but which is gaining popularity is linguistic analysis of raw text.  Linguistic Inquiry and Word Count (LIWC) is a quantitative text analysis software program that categorizes individual words into various dimensions to study individual speech.  The premise is that when words are analyzed as decomposed units of speech, a latent meaning of the individual’s thoughts, which are independent of context, are exposed for analysis. It is proposed that research be undertaken to determine whether LIWC analysis could be employed by law enforcement as an investigative tool to indicate deception or possible deception in written statements.

Buddy Broncho

Buddy Broncho made his first appearance in UCO's own newspaper The Vista. It was the October 3, 1932, issue where a Broncho appears wearing a UCO football uniform. He has appeared numerous times throughout the years from local Edmond papers in the 60's to state-wide papers in the 80's. The commissioning of the first ever live mascot appears in UCO's 1979 Bronze Book where Buddy Broncho made his first public appearance at Homecoming. Since that time, Buddy has been a fixture at UCO events and in the hearts of UCO students.
