For example:There was a mistake in the Funding statement, an incorrect number was used. The correct number is "2015C03Bd051.". The publisher apologizes for this mistake.The original version of this article has been updated. In the published article, there was an error. The abstract had errors in the number of therapy sessions in the methods and results. And the subheading "Results" appeared in the wrong place.A correction has been made to Abstract, Methods, second sentence. This sentence previously stated:"Three hour-long VRET sessions were delivered over two consecutive weeks."The corrected sentence appears below:"Three hour-long VRET sessions were delivered over three consecutive weeks."A correction has been made to position of the subtitle, "Results" in the Abstract. This section and the preceding section previously read: "Methods: Seventy-two individuals with high self-reported social anxiety were randomly allocated to 25 completers) or VRET alone (n=35;25 completers). Three hour-long VRET sessions were delivered over three consecutive weeks. During each session, participants delivered a 20-minute public speech in front of a virtual audience.Results: Participants in the VRET-plus-biofeedback group received biofeedback on heartrate and frontal alpha asymmetry (FAA) within the virtual environment and were asked to lower their arousal accordingly. Participants in both groups completed psychometric assessments of social anxiety after each session and at one-month follow-up. PSA improved by the end of treatment and overall social anxiety improved one month after the VRET across both groups. The VRETplus-biofeedback group showed a steadier reduction in FAA in the first VRET session and a greater reduction in self-reported arousal across the two sessions than the VRET-alone group."The subtitle, "Results" appears in the correct location below: "Methods: Seventy-two individuals with high self-reported social anxiety were randomly allocated to 25 completers) or VRET alone (n=35;25 completers).
