While prior studies found task-irrelevant threatening pictures are harder to ignore than neutral or other valenced ones, they only used static stimuli (pictures) not resembling real-life threat encounters. This study expands the scope by using auditory stimuli alongside videos with sounds and muted videos related to threatening weather conditions (e.g., thunder, lightning, rain) and neutral weather conditions. We seek to explore the impact of threatening task-irrelevant distractors on attentional executive control during a number-matrix task. Task-irrelevant distractors are chosen based on online ratings from an independent sample. Both experimental stimuli and ratings are accessible on the OSF page: https://osf.io/xzfhc/. In the number matrix task, participants search for numbers in a chess-like array in ascending order, starting from number 1, for 30 seconds in each trial. Based on a priori sample size calculation, we plan to recruit 75 participants. We plan to analyze the data with 2x3 mixed ANOVAs with threat level (neutral, threatening) as a within-subject factor and modality (visual, auditory, audiovisual) as a between-subject factor. Behavioral measures will include assessing the time to find Number 1 (RTs) and the total search time for Numbers 1 to 10. Based on the arousal stimulation effect hypothesis, we expect that in the threat compared to the neutral condition, participants will be slower to find Number 1 but will produce faster search times. Further, we expect that this effect will be more pronounced in the audiovisual condition compared to the audio- and video-only conditions.
