Chapter 6~ Sensation and Perception

In this chapter I learned about thresholds. For example an absolute threshold is the minimum stimulation needed for detection 50 percent of the time. The other threshold is the difference threshold. This threshold is the minimum difference between two stimuli needed for detection 50 percent of the time. I also learned about different laws and theories; like Weber's law and the signal detection theory. What I found most interesting about this chapter is the part that teaches us about the eye. My mom had laser eye surgery to perfect her vision and ever since then I have always been interested in the eyes. I also enjoyed reading about all the senses and how they work. What was really interesting in this chapter was ESP. I have always been intrigued by ghost stories and scary movies so this part of the chapter was interesting to me. One of the varieties of ESP is clairvoyance and there is a local band called clairvoyance; I just think that is interesting and now I know what the band name stands for!
