Lie detector tests works because of a few reasons o Children are raised w/ really strong social norm where you should not lie o We have anxious response when we violate social norms most of the time People have internalized the norm that you are not supposed to lie o When we are anxious, this causes a series of predictable changes in our body Lie detection tests are not admissible in court – they label a lot of innocent people as liars o Only catches about 80% of guilty people’s lies, 40% of the time it causes an innocent person lying One characteristic of psychopath is fearlessness o Someone w/ psychopathy is more likely to commit violent crime o Someone w/ psychopathy is less likely to have normal sweat of a fear anxiety response Some people beat lie detector test by giving a stressful response even when speaking the truth o Some people use a sharp pin in shoe and press hard on pin to elicit a response even when telling the truth Lecture 6 – Sensation Psychology in The News When perceiving color, brain is taking in information about what does the background light look like o Our brains take information about the lighting and discount it to try to figure out the color of the object Dress was white/gold if you perceive it to be in a shadow, dress was blue/black if you perceive it to be in bright light Sensation and Perception Sensation – mental process resulting from immediate external stimulation of a sense organ o Sensation is about how info from physical world get into our brain o Specialized cells in our sense organs take physical energy from world & transduce it into electrical signals that can be transmitted by neurons

o Transduction – process by which specialized cells convert physical energy (sound waves, light waves, pressure) into electrical signals that can be sent from one neuron to another neuron We actually have SIX senses not five – (1) Sight (2) Sound (3) Touch (4) Taste (5) Smell (6) Vestibular Sense o Vestibular sense – tells our body where we are in space, ESP extrasensory perception Perception o Perception is about making sense of the world around us Echolocation – can be used to see things by using acoustic energy (sound waves) rather than light energy o Energy comes out from the individual, bounces off of everything in the environment, and returns to listener What’s Cooking in the Lab Vision involves different receptors o Vision depends on specialized cells in the back of your eyeball on the retina called rods & cones Rods & cone are differentially sensitive to light – only cones give you info about color Rods and cones are distributed in a particular way on your retina o Rods – responsible for vision at low light levels, do not provide color vision and have low spatial acuity o Cones – responsible for vision at higher light levels, provide color vision and high spatial acuity Neurons from the rods and cones will leave the eye close to center of our visual field o Where the neurons leave the eye, there are no rods and cones – blind spot

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
