The psychometric properties of the late positive potential during emotion processing and regulation
Abstract
The late positive potential (LPP) is a commonly used event-related potential (ERP) in the study of emotion and emotion regulation. The LPP has also been evaluated as a neural marker of affective psychopathology. The psychometric properties of this component have not been examined, however. The current study was conducted with the aim of addressing two questions: how internally consistent is the LPP, and how many trials are necessary to obtain a stable LPP? Fifty-eight participants completed an emotion regulation task. First, split-half reliabilities were computed for the LPP and for difference waves revealing emotion effects (negative minus neutral) and regulation effects (reappraise minus negative). Second, averages including progressively more trials were evaluated and compared to overall participant averages. These data indicated good-to-excellent reliability for neutral, negative and reappraise trials, as well as difference waves. Furthermore, the LPP varies little after 8 trials are added to the average and the difference waves vary little after 12 trials are included. Together, the findings of the current study suggest that the LPP demonstrates good internal consistency and can be adequately quantified with relatively few trials.

“Although our choice of filtering cutoffs, artifact rejection parameters and the use of the ocular correction method developed by Gratton et al. (1983) are common in the literature, such choices do vary between labs.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
