Hello,
I have a database of Stroop data that I am not sure how to analyze/ interpret. What I am looking for (I believe) are the differences in average latency between the congruent and incongruent trials. Here is a snapshot of what the variables in the database look like:
subject trialcode stimulusitem1 trialnum latency correct congruentlatency incongruentlatency
1 bluecongruent blue 3 1520 1 1520 0
1 redincongruent green 4 2425 1 1520 2425
1 blueincongruent red 5 2543 1 1520 2484
From my understanding, the congruentlatency and incongruentlatency compute average latency response times for the congruent and incongruent trials using the latency response times. For each subject, the last entries for the congruentlatency and incongruentlatency columns represent the subject's average latency times for the congruent and incongruent trials for the entire task. I've tried taking this difference for each subject, and running some analyses, but I believe this is not the appropriate method to analyze this data. Any suggestions on how to analyze this for what I'm looking for (please see above)?
Thanks in advance!
