In this laboratory experiment, you will be working as an amateur seismologist to locate the epicenter of a fictional earthquake. Your task will involve interpreting seismograms from three seismograph stations; determining the difference in time between the arrival of the P waves and arrival of the S waves from the earthquake; using a travel-time graph to determine how far each seismograph station is from the epicenter; and using the technique of triangulation to pinpoint the location of the quake.…

The participant was instructed to name each of the INK colours as quickly as possible, starting at the top of the list. The experimenter signals ‘GO’ and the participant names all of the INK colours. Once the participant has named all of the colours on the list, the participant says STOP. Reaction time is measured with a stopwatch from the time experimenter says GO until the time the participant says STOP. At the completion of each list, reaction time is recorded to the nearest 10th of a second. Experimenter then moves on to the next condition. Once all the conditions are done, the experimenter and participant swap roles. Upon completion of the experiment, everyone handed in the results to collaborate the data.
