<p>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 <i>reactivity</i>) and 1900 ms after picture offset (assessing <i>recovery</i>). 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.
