Simultaneous Same/Different Task This is an example of the simultaneous same/different task used to train pigeons. An array of "icons" will be displayed. Red and green choice buttons will be displayed - click on one and you will be told whether you are correct. This program differs in small ways from the one used in our experiments. In the actual pigeon studies: when a pigeon chose correctly, they received a food reinforcer when a pigeon chose the wrong key, the chamber was darkened and it was required to repeat the same trial (only the first trial was scored, though) the pigeons had to complete a 20-30 peck orienting response requirement (pecks at the display) before the choice keys were displayed; when the choice keys were displayed, the screen colors reversed (to white on a black background) until a choice was made. the real experiment used block randomization NOTE: I have noticed that the first few icons usually flicker on the first trial as it loads the pictures in the background. This degree of flicker is a function of the speed of your machine and the speed of your connection. After the first trial, icons are displayed normally. If you encounter problems or wish to provide feedback, please contact me Mike Young. Please click on the white screen below to begin the experiment.
