+xHello! I am very new to Stroop task and have only just used it in my thesis (an emotional Stroop task) so I apologise if this question has an obvious answer. I have collected my data and I was wondering how to go about analysing it. From what I understand I will have to calculate an interference score (e.g., interference score = neutral word  negative word). For the neutral word score, do I just average the reaction times for all the neutral words and use that to calculate the interference score for each negative word and then average that to get a total score for negative word for each participant? Also how do the correct and incorrect responses fit into this? I am sorry if this is obvious! I am new to Stroop. Thanks! Sherry Assuming you used this script, https://www.millisecond.com/download/library/v5/stroop/emotionalstroop/emotionalstroopwithkeyboardinput.manual , bias scores are already calculated and provided in your summary data file. See the expressions.Bias_Agg to expressions.Bias_Pos variables in the output. They are calculated as the difference in mean latency between the emotional category minus the neutral category, as you can see here: <expressions> /percCorrect_Agg = (values.correct_aggressionwords/trial.aggression.trialcount) * 100 /percCorrect_Neg = (values.correct_negativewords/trial.negativeword.trialcount) * 100 /percCorrect_Neu = (values.correct_neutralwords/trial.neutralword.trialcount) * 100 /percCorrect_Col = (values.correct_colorwords/trial.colorword.trialcount) * 100 /percCorrect_Pos = (values.correct_positivewords/trial.positiveword.trialcount) * 100 /meanRT_Agg = values.sumrt_agg/values.correct_aggressionwords /meanRT_Neg = values.sumrt_neg/values.correct_negativewords /meanRT_Neu = values.sumrt_neu/values.correct_neutralwords /meanRT_Pos = values.sumrt_pos/values.correct_positivewords /meanRT_Col = values.sumrt_col/values.correct_colorwords /Bias_Agg = expressions.meanrt_agg  expressions.meanrt_neu /Bias_Neg = expressions.meanrt_neg  expressions.meanrt_neu /Bias_Pos = expressions.meanrt_pos  expressions.meanrt_neu /Bias_Col = expressions.meanrt_col  expressions.meanrt_neu</expressions> As you can also see in the user manual as well as in the above, only latencies stemming from *correct* responses are considered.
