<div dir="ltr">Hello Everyone, <div><br></div><div>I am trying to use E-prime to build a stop signal frustration task, but I have encountered a few complications in building the task. </div><div>At the moment, I am trying to create an initial script that would allow E-prime to automatically run a participant in a condition (high frustration or low frustration) depending on the participant number that I input before running the experiment. </div><div>So for example, if I wanted to run 80 participants, half would be placed in the high frustration condition and the other half would be placed in the low frustration condition. </div><div><br></div><div>I have some ideas about how this could theoretically be carried out, but I'm not sure if/how this can actually be implemented in the script. For example, I would want the initial script to begin by telling the program to pull 40 random numbers 1-80 (I would need to somehow make the same 40 numbers be pulled each time). The 40 numbers pulled would be placed in the low frustration condition where pctcorrect (percent correct)=.80. </div><div>If else, (so if one of the other 40 numbers were pulled), place the participant in a high frustration condition where pctcorrect (percent correct)=.30. </div><div><br></div><div>e.g. If I were running the program and I typed in my participant number as 3 and 3 was one of the random numbers pulled between 1 and 80 then the program would automatically run the stop signal task placing the participant in the low frustration condition where pctcorrect=.80 (where participants could accurately inhibit on 80% of stop signal trials). </div><div><br></div><div>However, if the participant ID number was 8 and 8 was not one of the 40 random numbers initially pulled between 1 and 80 then the program would place the participant in the high frustration condition where pctcorrect=.30. </div><div><br></div><div><br></div><div>Is this something that is possible in E-prime? </div><div><br></div><div>I hope this makes sense. Thanks in advance for your input! </div><div>-Kelsey </div><div><br></div></div>
