Experiment 1: Results from a 3 (sound sequence) Ă— 2 (valence) repeated-measures ANOVA on stimulus ratings, reaction times (RT), and phasic sympathetic arousal as estimated from skin conductance responses (SCR); and from a one-way ANOVA on tonic sympathetic arousal as estimated from spontaneous fluctuations (SF) in skin conductance.
<p>For the sound factor, only the a priori contrasts unpredictable vs. predictable and predictable vs. silence are tested.</p><p>Experiment 1: Results from a 3 (sound sequence) Ă— 2 (valence) repeated-measures ANOVA on stimulus ratings, reaction times (RT), and phasic sympathetic arousal as estimated from skin conductance responses (SCR); and from a one-way ANOVA on tonic sympathetic arousal as estimated from spontaneous fluctuations (SF) in skin conductance.</p

Schematic showing the crowding experiment and selected examples of stimuli used in the experiment.
<p><b>Panel A:</b> A fixation point was first presented for 1500 ms, followed by a target/distracter array (4° spacing/10° eccentricity condition shown here) for 60 ms. Then, a mask appeared for 200 ms. Finally, a response screen displaying a fixation point was shown and the subjects were required to register whether they saw an upright or 90° tilted target “T” by pressing a key. <b>Panel B:</b> 2° spacing/10° eccentricity condition (top left); 8° spacing/10° eccentricity condition (top right); target-only/10° eccentricity condition, 90° tilted target “T” (bottom left); 8° spacing/8° eccentricity condition (bottom right).</p
Accuracy and fitted logistic curves as a function of spacing at 8° eccentricity (panel A) and 10° eccentricity (panel B) in schizophrenia patients and healthy controls.
<p>Vertical dotted lines indicate critical spacing. Values represent the mean ± standard error of mean.</p
Raw fMRI data of controls and patients
Raw fMRI data of 14 healthy controls (HC) and 15 chronic low back pain patients (CLBP). Subject had to perform a motor imagery (MI) task during scanning session
Brain activity of the chronic Low Back Pain (LBP) group, peak activations.
<p>Cluster maxima of brain activity of the video clips of activities of daily living (“Activities”) and walking activities (“Walking”) together. All results are false discovery rate corrected (FDR, q<0.05).
