Pure Selector

The pure selector is a selector which only allows for pure strategies. This selector is good for games like Prisoner's Dilemma or Hawk-Dove when you want the subject to play strictly defect or cooperate.

In the above screenshot, this player chose strategy A for the entire period, and the other player chose B. The numbers in the grid on the left side of the window refer to the different payouts. The subject picks either the top or bottom row (making the subject the 'row player') while the subject's opponent plays either in the left or right columns (making that player the 'column player'). This use of Pure is for a Matrix2x2 game, where each cell has values set ahead of time. The pure selector forces the players to play with A or B, and will highlight the choice that player made. The square that is highlighted by both the row and column indicates which payoff the player will receive. The player receives the amount listed on the left of the pair of numbers in the square.

The below table is an example of the config file pure. The actual file has the items separated by commas, which is why the config files are CSV (comma separated value) files.
