Recently, the existence of a prediction error signal to the omission of expected punishment in skin conductance recordings has been posited. Here, we re-analyse an existing dataset on aversive delay conditioning and find no evidence for such a signal. We discuss methodical reasons for this discrepancy and technical implications for estimation of central processes from skin conductance data.
