A study was done to see why crickets chirp and the reactions to stimulus that caused the audible sound to occur. Throughout the experiment they tested how a target (male) cricket interacts with different stimuli in the form of both male and female cricket. Their methods revolved around getting quantitive data on three separate behaviors that occurred in the target male: locomotion(any time the target did a continuous movement), contact(counted when the target touched a stimulus with any part of its body), and chirping(audible, chirp sound with leg or wing movement from the target). The target was rotated each test, so each data point came from a different cricket with the female stimulus, being the same each time, and their previous target becoming the male stimulus. They would place the two male crickets in the target bin and let them acclimate for two minutes before they began collecting data from the target for three minutes. Then the female stimulus was placed in the bin and left…
