Your participating in this study is voluntary.</p>\n\n<p>The lead investigator is Prof. Dr. Julian Keil, Department of Psychology at Kiel University (CAU).</p>\n\n\n<p> <h4>1. Purpose of the study </h4> </p>\n\n<p>The study is used for fundamental research regarding perception. Prof. Dr. Keil's team investigates multisensory perception, viz. the integration of visual and auditory information which results in our complex perception of our environment.</p> \n  \n<p>In the following experiment, we'll present to you a combination of simple symbols and sounds and ask you to react as fast as possible by pressing a key on your keyboard. In this study, we're testing the influence of the perception of a stimulus in one modality on the perception of a stimulus in another modality. This study doesn't test any clinical interventions.</p>\n\n<p> <h4>2. Procedure</h4></p>\n<p>If you decide to participate in this study, the procedures and your task will be explained to you. During the experiment, the aforementioned stimuli will be presented, and you will have to respond to them by pressing certain keys on the keyboard.</p>\n <p>There will be practice trials, so you can learn the task before the start of the actual experiment.</p>\n\n<p><h4>3. Behavior during the study</h4></p>\n\n<p>Please follow the instructions as strictly as possible. The experiment is about the perception of visual and auditory stimuli. There are no right or wrong answers.</p>\n\n<p><h4>4. Benefits</h4></p>\n\n<p>Participating in our study will not benefit you directly, but you will help us expand the scientific knowledge on the topic of multisensory integration. </p> <p>Students of psychology at Kiel University (CAU) can get course credit for the participation in the study.</p>\n\n<p><h4>5. Risks</h4></p>\n</p>Participating in our study is not associated with any foreseeable risks.</p>\n\n<p><h4>6. Privacy</h4></p>\n<p>If you are willing to participate in our study, you give the lead investigator and his team permission to collect and analyze your personal data. The collection and analysis of your data will take place at the Department of Psychology at Kiel University (CAU). Both will be contributed to by the lead investigator and his team. Personal data can be your birthday, your gender, information regarding your physical and mental health or other information you are asked about during the study. The lead investigator and his team will use these data for purposes of managing and carrying out the study and for purposes of research and statistical analysis.</p>\n<p>All data will be processed and stored in encrypted form. Therefore, no collected data (e.g. the answers to the questions on the computer) can be connected to you. As per the legal retention period, all collected data will be stored on a password encrypted computer for a maximum of ten\nyears and will be destroyed afterwards. You may disagree with the further processing of your data and request their complete erasure at any time.\n</p>\n<p>You are entitled to disclosure of all your personal data that are available to the investigators. You are also entitled to the correction of inaccurate personal data. In this case, please contact the lead investigator directly. You will find his address and phone number further on in this text.</p>\n<p>Please be aware that the results of this study may be published in a scientific journal. Your identity will remain anonymous.</p>\n\n<p><h4>7. Right to question / Disclosure requirement</h4></p>\n<p>You are entitled to ask the investigators any questions regarding the study at any time. In this case, please contact the lead investigator or his team: </p>\n\nProf. Dr. Julian Keil <br>\nBiologische Psychologie<br>\nOlshausenstraße 62 - R. 306<br>\n24118 Kiel<br>\n<br>\n0431 / 880 - 4872<br>\nkeil@psychologie.uni-kiel.de<br>\n\n<p> <h4>8. Voluntariness of participation</h4></p>\n<p>Your participation is voluntary. You can only participate in this study if you consent. You are entitled to withdraw your consent to participating in the study at any time informally and without giving reasons. There will be no adverse consequences for you. The same applies to the discontinuation of participation, the withdrawal of your declaration of consent, and your disagreeing with the (further) processing of your data.<p>\n\n<p><h4>9. Costs</h4></p>\n<p>Participation in the study is not associated with any costs for you.</p>\n<br>\n</div>\n</main>\n\n<footer style=\"background-color:grey;\"> \n  <em>Continue by pressing Space on your keyboard</em>\n</footer>\n\n",

Please indicate if you saw one, two or three flash(es) by pressing a key on your keyboard when you see a questionmark.\n  \n<p>Please press <strong>B</strong> if you saw <strong>0 flashes</strong>, <strong>N</strong> if you saw <strong>1 flash</strong> and <strong>M</strong> if you saw <strong>2 flashes</strong>. <p>\n\n<p>In some blocks you'll get an additional task. In these cases, you will see a letter before each flash/beep. Please try to memorise this letter and indicate, whether the current letter is the same as the letter before, the penultimate letter or the same as a beforehand specified letter (e.g. an \"X\"). Before each new task, you'll get precise instructions, so please don't worry if you didn't understand everything now. <p> Please just remember that in each of these letter-tasks, you'll have to press the <strong>X</strong> on your keyboard, if the letters match. Don't press any key, if the letters don't match. </p> \n\n<p>Before each block, you'll get the chance to practice the task in a short training block. After that, the main block starts. You can take a break between the blocks if you want to, but please be aware that you can't take a break during a block. Each main block is about 5 minutes long. <p>\n</main>\n<footer style=\"background-color: grey;\">\n<em>Please press the space bar to continue.</em>\n</footer>\n</div>",
