Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
30 positive, 30 negative, and 30 neutral pictures were displayed individually on separate trials. Participants responded as quickly as possible to the border color (purple or yellow) presented during the first 0.5 s of the picture presentation in order to maintain attention during the task. Startle probes were presented at 2900 ms after picture onset (assessing reactivity) and 1900 ms after picture offset (assessing recovery). Note: to avoid publication of an IAPS picture, the example negative picture was selected from the author’s personal collection to be representative of a prototypical IAPS picture. As the mother of the baby in the photograph, she has given written informed consent, as outlined in the PLOS consent form, to publication of their photograph.
