Answering this questionnaire will not affect your participation in this study, nor will it affect your payment for participation in this study. You may answer some of these questions, all of these questions, or none of these questions. The questions are designed for one of two things:</p>\n <ol>\n <li>Provide us with information that will better help us conduct the experiment and analyze the data from the experiment.</li>\n <li>Provide us with information regarding participant demographics (age, race, sex, etc.) that is often requested by groups monitoring and/or funding our research. This information is requested by groups such as the National Science Foundation (NSF), the National Institute of Health (NIH), and the university's Institutional Review Board (IRB) to ensure that human research studies accurately sample the population base of the region. This also helps to make sure that certain population subsets are no longer wittingly or unwittingly underrepresented in scientific research data.</li>\n </ol>\n <p>If after you complete and submit this questionnaire you later decide that you wish to amend or erase any information you supplied us, please let us know at <strong>[email protected]</strong>, as you are always free to make changes to this info.</p>\n </div>\n </main>\n\n <body>\n\n <form>\n\n <div id=\"endForm\" class=\"survey\">\n <ol>\n <li> How were you playing the audio in this study? \n <select id=\"audioequip\" name=\"audioequip\">\n <option>In-ear headphones/earbuds (cost $30 or less)</option>\n <option>In-ear headphones/earbuds (cost $100 or less)</option>\n <option>In-ear headphones/earbuds (cost more than $100)</option>\n <option>Over-the-ear headphones (cost $30 or less)</option>\n <option>Over-the-ear headphones (cost $100 or less)</option>\n <option>Over-the-ear headphones (cost more than $100)</option>\n </select>\n </li>\n\n <li> Age \n <textArea id=\"age\" name=\"age\" placeholder=\"Enter your age here.\" ></textArea>\n </li>\n <li> Sex \n <select id = \"sex\" name=\"sex\">\n <option value=\"NA\" selected>Other (non-binary, agender, etc)</option>\n <option value=\"Female\">Female</option>\n <option value=\"Male\">Male</option>\n </select>\n </li>\n\n <li> Ethnicity \n <select name=\"ethnicity\">\n <option value=\"NA\" selected>N/A</option>\n <option value=\"Hisp\">Hispanic or Latinx/Latine</option>\n <option value=\"NonHisp\">Not Hispanic or Latinx/Latine</option>\n </select>\n </li>\n\n <li> Race \n <ul>\n <li><input type=\"checkbox\" name=\"race\" value=\"amerind;\">American Indian / Alaska Native</input></li>\n <li><input type=\"checkbox\" name=\"race\" value=\"black;\">Black or African-American</input></li>\n <li><input type=\"checkbox\" name=\"race\" value=\"pacif;\">Native Hawaiian or Other Pacific Islander</input></li>\n <li><input type=\"checkbox\" name=\"race\" value=\"asian;\">Asian</input></li>\n <li><input type=\"checkbox\" name=\"race\" value=\"white;\">White</input></li>\n <li><input type=\"checkbox\" name=\"race\" value=\"unknown;\">Unknown</input></li>\n <li><input type=\"checkbox\" name=\"race\" value=\"other;\">Other</input></li>\n If Other:\n <input type=\"text\" name=\"raceother\"/>\n </ul>\n </li>\n\n <li> Were you born in the USA? \n <select id=\"where_born\" name=\"born\">\n <option>no</option>\n <option>yes</option>\n <option>prefer not to answer</option>\n </select>\n </li>\n\n <li> Did all of your parents speak Engish at home growing up? \n <select id=\"parent_english\" name=\"parent\">\n <option>no</option>\n <option>yes</option>\n <option>prefer not to answer</option>\n </select>\n </li>\n\n <li>(optional) if not, what languages did they speak?\n <textArea id=\"parent_lang\" name=\"lang\" placeholder=\"Enter language here.\"> </textArea>\n </li>\n\n <li> Enter any comments you have below.
