This is the data to replicate all analyses from Urai AE, Braun A, Donner THD. (2017) Pupil-linked arousal is driven by decision uncertainty and alters serial choice bias. Nature Communications, 8: 14637.See https://github.com/anne-urai/pupilUncertainty for the analysis code, including detailed instructions for replicating the figures from the manuscript.You probably only want to use <code>2ifc_data_allsj.</code><code>csv</code>. Column names:<code>stim</code>: generative stimulus identity, i.e. 'weaker' (-1) vs 'stronger' (+1)<code>coherence</code>: generative coherence difference from referenceNote: a column <code>stim</code> * <code>coherence</code> will get you the signed motion coherence, that is most useful for generating regular choice-based psychometric functions.<code>difficulty</code>: level of difficulty within the session; see 'Task and procedure' in the Methods section. <code>motionstrength</code>: the estimated motion energy in each generated video. Correlates highly with <code>stim</code>*<code>coherence</code>, as shown in Figure 2c<code>resp</code>: response of the subject<code>rt</code>: reaction time, after offset of the second stimulus<code>correct</code>: feedback given<code>correctM</code>: feedback that should have been given, had the exact stimulus identity been based on the motion energy filtered values (rather than the generative values)<code>trialnr</code> within each block<code>blocknr</code> within each session<code>sessionnr</code> within each sj<code>subjnr</code> participant IDbaseline_pupil, decision_pupil, feedback_pupil, trialend_pupil, response_pupil: pupil dilation at various epochs during the trial<code>int1motion</code>, <code>int2motion</code>: filtered motion energy values during the reference and test interval. Their difference generates the <code>motionstrength</code> column.<code>rtNorm</code>: z-score(log(rt))<br><code>correctM:</code>
