Survey design
Six memory questions with different combinations of audio and visual components were integrated into a Qualtrics online survey to test the ability of the working memory to respond accurately in a stressful versus controlled environment. All participants received the same questions in the same order. The survey questions are available in Fig. Two questions tested the efficiency of audio-only instruction (Q3 and Q5) by providing an audio sample of random words or sounds with no context. The next screen targeted the working memory with a question about the audio content where the participant selected their answer from a list of multiple-choice options. Two questions tested the efficacy of visual-only instruction (Q2 and Q4) by providing a picture on the first screen with no additional instruction and a memory question with a list of multiple-choice options on the next screen. Participants selected an arrow button to move to the second screen, and they were not able to return to the previous screen at any time. Two questions tested a blend of audio and visual components (Q1 and Q6). One question verbally asked the participants to place the pictured four buildings in order from shortest to tallest (Q6), and the other asked participants to identify the picture of the instrument that they heard in the audio clip (Q1).
