This will help on determining how long it took players to associate the color/button process. Same process as problem 1. Problem 3 Problem 4 (A) The effects are interactive because the lines are non-parallel. (B) The two variables affect the same processing stages because Mean lane deviations depend both on traffic levels and on what kind of phone is being used P h o n e t y p e
Problem 5 a) Transition points were calculated by averaging the threshold of every series, this means adding the last No to the Yes and dividing it by 2 (when the pain was perceived). The pain threshold is just the average of the transition points (127 +131+127+127+125+131+129+133)/8 = 128.750 b) Absolute threshold because purpose was to determine threshold for detecting a stimulus (pain) c) Method of Limits was used to determine the pain threshold Problem 6 He should make it 5-10dB below the pain threshold, so in that way the worker who might want to remain does not feel any pain, human factors should make a comfortable environment. Also, alarms should have a 75dB as regulated by the National Fire Association, so it should be expected to lower the pain threshold. Problem 7 127 131 127 127 125 131 129 133 128.750

Problem 8 False Alarm = 75% Hit = 70% Hit Z (.300) = -.520 .520 distance from mean False Alarm Z(.250) = -.670 .670 distance from the mean D’ = .670 - .520 = .150 Problem 9 a) Inspector 2
B Yes, if we take a look at the table, the liberal, which is closest to (1,1) has a higher probability of hitting ( finding any gel) on the luggage, while more conservative is closer to (0,0). C Inspector 2 has the highest sensitivity. The line point towards closer to the hit rate axis. Inspector 1

### What students are saying

• 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.
