Alhamdulillah (praise to be God), finally, I have finished my PhD!

Doing a PhD is a journey. It is a hardworking process and full of tears and joy. It is one of my dreams in life. I could not finish the remarkable journey without the assistance of many colleagues, friends, and people around me.

First of all, I would like thank Allah, the God almighty, for giving me power, knowledge, and strength to finish my PhD.

I would like to express my deepest gratitude to my promotor, my primary supervisor,

Niels Taatgen. I still remembered the first time he accepted my PhD application. I

was so happy at that time, and I immediately told my Mom that I would go to Groningen. I have been supervised by a great supervisor and a great mentor for these 4 years. I have learned a lot from him, not just academically but also many aspects in life. He has taught me how to listen to other people, how to analyze the situation, how to think clearly, logically, and analytically, and how to trust in myself. I have never been so interested in academia before, and now I understand this field more and will continue doing research to be a full Professor someday. Thank you again Niels for all your assistance and support.

I would like to thank my daily supervisor, Fokie Cnossen, for helping me with almost everything. She is a great supervisor and a great mentor indeed. She taught me about PhD life, how to deal with my project, how to be confident, how to handle presentations, how to handle questions, and many more. She also introduced me to Arie, who helped me with heart rate instruments. She is very analytical and helped me how to write publications professionally. I always enjoyed having a discussion with her in all our weekly meetings. Thank you again Fokie for all your assistance and support. I would like to thank all members of the assessment committee: Prof. K.A.

Brookhuis, Prof. D. Van Der Linden, and Prof. P.A. Hancock for spending

time assessing and giving suggestions to my thesis.

I thank all my colleagues in the Cognitive Modeling group: Marieke, Jelmer,

Jacolien, Katja Mehlhorn, Katja Paul, Stefan, Corné, Christina, Hermine, Abby, Oscar, Hagit, Mark, Hang, and Lionel. Everyone has been helping and

supporting me during my PhD, thank you!

I would like to thank Lembaga Pengelola Dana Pendidikan (LPDP) for sponsoring and funding my PhD for 4 years.

My sincere gratitude to my lovely mother Enny Purwanti for bringing me up to be a great person and a great man. May Allah bless you, give you a healthy life, and provide you the best reward in life. You are one of my greatest motivation for me to finish my PhD.
