April 2018 – The first month

In my first week I met with my professor, Sonja Kotz, in order to kick-start the project. The agenda included:

  1. Ethics application
  2. Stimuli and sample population
  3. Training

For each of these, up to this date I have achieved:

  1. Ethics: I submitted the application on 23rd of April. The application included documents such as the information letter for subjects (including both EEG, fMRI and TMS), statement of consent form (for EEG, fMRI and TMS), debriefing form, and advertisement. The application form was submitted online through the Ethics Reveiw Committee Psychology and Neuroscience (ERCPN) of Maastricht University. The application is planned to be discussed at the next meeting of the committee, which is on May 14th. In order to prepare the documents for TMS I had a meeting with Sonja and Alexander Sack at FPN day. His assistant sent me the TMS forms that I needed to include in the ethics application; the TMS ethics application is dealt with internally in their group and there is no extra application needed with the ERCPN for this method. He also invited me to his group meeting, which is on May 8th.
  2. Stimuli and sample population: The main question was whether we run the study in Dutch or German. This decision is dependent on two factors: a) the availability of the targeted populations in Maastricht (both musicians and non-musicians) and b) the availability of high quality audio samples in German or Dutch on the public domain Librivox.
    • On the populations: I have contacted the Conservatory via email twice, but they have not responded up to this date. I have had a meeting with Niels Diesbergen, a PhD student of Elia Formisano, who has collaborated with musicians from the conservatory befoe. We will try to establish the contact with Elia’s help.
    • On the stimuli: I have been listening to various stimuli from Librivox. There is 10x more material in German than in Dutch. I contacted my collaborator in Berlin Thanos Lykartsis in order to discuss about how to model the linguistic rhythm from the auditory signal. This led to a joint meeting with Sonja, Ben Schultz (currently post doc in the BAND-LAB) and Thanos, in which we discussed how to approach the analysis of the speech signal in order to correlate it with the EEG and fMRI data. Also, we decided to employ Ben’s adaptive beat perception task in the behavioural part of the study. We then discussed how beat tracking algorithms (Ellis, 2007; Böck & Schedl, 2011; Lykartsis & Lerch, 2015) work, what are the strengths of each algorithm and how these strengths might suit well or less well to speech auditory signal than to music auditory signal. In order to avoid turning the rhythm identification task into a speaker identification task, we decided to choose stimuli from two male-voiced and two female-voiced speakers. This way, the timbre differences will not be tagged as rhythm differences by the beat tracking algorithms.
  3. Training: I have registered for two training courses to take in May.
    • On the 2nd and 9th of May I am participating in Problem-based learning (PBL) training, which is a novel method of teaching used in Maastricht University. I will be trained to become a tutor, in order to complete my teaching tasks, as included in my MSC fellowship timeline and in my contract with Maastricht University, which poses that 10% of my working hours need to be devoted to teaching.
    • On the 7th, 14th and 28th of May I am participating in fMRI security and certified user training in the Maastricht Brain Imaging Centre (M-BIC).

Last, on April 30th, last day of the month, I presented my proposed project to the BAND-LAB meeting. Here is my presentation: NERHYMUS_plan_30042018

On a slightly different note, on April 17th, I took part in the Faculty of Psychology and Neuroscience Day, in which I met many of the people of the Faculty, from PhD students to Professors. Participants were informed about the ongoing PhD projects and entertained with fun workshops on several topics such as Mindfullness and Games as interventions in teaching and learning. Some pictures:

On this event I also met Isabelle Grosch, a new colleague from the Communication Department. She brought me to contact with her colleagues and we have scheduled an interview in order to promote NERHYMUS. More on this to come in May.

April was creative and fruitful. Things are starting to roll in Maastricht. I am focused on work and I plan to keep this pace until the first deliverable in August. Then, and before starting the measurements, I will have to take a little break into the sun and the sea of Crete.
