Hi, We are preparing an experiment in which participants are asked to gather information about four options which names are presented simultaneously on the screen. After they click on one of the options an information about this option should appear on the screen. They can choose which option they want to get information about and can ask for several information about each option (previous information disappears when new information is presented). In our script we have sets of information about each option (=items). However we don’t know how to arrange it so that the presentation of those information (=trial?) depends on the response from participant (if they click on optionA then item from list A is presented, if they click on optionB then item from list B and so on). Thanks in advance for your help!
