    uncontrollable and shows an observer signs of every emotion. It shows signs of deceit as well. Usually these are undetectable, but with some training they can be detected and used in investigations. Therefore, facial micro-expressions should be admissible in federal investigations. We need a replacement for polygraphs, and micro-expressions are a fine candidate. The previously used lie detector, the polygraph, is unreliable. This is because “physiological responses measured by the polygraph are…

    For instance, many paradigms in lie detection studies include memory confounds, which make it difficult to isolate the brain processes specific to deception. Farah et al. (2014, p. 125) cite a study by Gamer et al. as an example of this, in that Gamer et al. found showing participants pictures they had previously memorized resulted in activation in the same brain areas that are often implicated in studies of deception. Satel and Lilienfeld (2013, p. 79) cite an additional memory confound in that…

    A polygraph, or a lie detector, is a device used to detect duplicity by replicating a subjects inner reactions on a scroll of paper. A subjects reactions to a particular yes or no question would then be recorded on to one of the multiple graphs the polygraph produced. Many people feel as if a polygraph is the key to figuring out whether a person is either innocent or guilty when investigating crimes such as murders but, what they may not know is that a polygraph cannot fully be trusted. In the…

    Deception skills involve the ability to detect when someone is deceiving you and the ability to convincingly deceive others. A study conducted by Ranick, Persicke, Tarbox, and Kornack (2012) was the first to succeed at teaching children with autism to detect when others were lying to them. They focused specifically on lies in which another student tried to exclude them or take their possessions. Using behavioral skills training consisting of rules, modeling, roleplay, and immediate feedback,…

    concentration of Triton-X to be 0.05%, so 1 mL of 0.5% was added to the final 10 mL matrix. Dr. Doolittle’s handout suggested that the optimal dithizone concentration was 50 μM in 10 mL, so 0.5 mL of 1μM dithizone was added to the matrix. 1 mL of solution was added to the matrix, along with 3 mL of water. In previous trials, 0.5 mL of buffer was added to solution (and water was added appropriately to get to 10 mL); however, this was later modified (see table below), as it was crucial to main a…

    warrant. The case that brought this to be was Florida v. Jardines. Jardines’ front door was closed and Franky the chocolate Labrador got a good enough whiff of what was inside.

Police felt that provided enough ground to obtain a search warrant, and they arrested Jardines with more than $700,000 worth of marijuana (Gray). Jardines’ attorney argued Franky’s sniff was unreasonable and does not constitute with the protection guaranteed…
