Our new article ‘Duration Estimation of Angry and Neutral Faces: Behavioral and Electrophysiological Correlates’, published in Timing & Time perception is now online. Lisa Eberhardt, Ferdinand Pittino, Anna Scheins, Anke Huckauf, Markus Kiefer and Katrin Kliegl aimed at investigating the processes underlying the temporal overestimation of emotional faces by combining behavioral and electrophysiological correlates in a temporal bisection task. Subjective ratings and the early posterior negativity confirmed encoding and processing of stimuli’s emotionality. However, temporal ratings did not differ between angry and neutral faces. In line with this behavioral result, the Contingent Negative Variation (CNV), an electrophysiological index of temporal accumulation, was not modulated by the faces’ emotionality. Duration estimates, i.e., short or long responses toward stimuli of ambiguous durations of 1000 ms, were nevertheless associated with a differential CNV amplitude. Interestingly, CNV modulation was already observed at 600–700 ms after stimulus onset, i.e., long before stimulus offset.
