PS-M67 Structure and Function of the Brain
This module provides an introduction into basic human functional neuroanatomy. Students will learn about the principles underlying the anatomical organisation and functional segregation of the human brain. Evolutionary and developmental origins of brain structure and function, as well as the relation between brain structure and function will be discussed.

PSY319 Independent Research Project
Students conduct an independent research project under the supervision of a member of staff. The research topic is decided in conjunction with supervisors and Research topics. Students must design, conduct, analyse and write up a piece of research in order to achieve Graduate Basis for Chartership with the British Psychological Society (BPS). They must also complete an Ethical Considerations Form, showing that they have considered and resolved ethical issues relating to their project, and that they have implemented appropriate best practices for improving the reproducibility of their research.

PSY319W Prosiect Ymchwil Annibynnol
Mae myfyrwyr yn cynnal prosiect ymchwil annibynnol dan oruchwyliaeth aelod o staff. Penderfynir ar bwnc yr ymchwil ar y cyd â goruchwylwyr a phynciau Ymchwil. Rhaid i fyfyrwyr ddylunio, cynnal, dadansoddi ac ysgrifennu darn o ymchwil er mwyn cyflawni Sail Graddedig ar gyfer Siarter gyda Chymdeithas Seicolegol Prydain (BPS). Rhaid iddynt hefyd lenwi Ffurflen Ystyriaethau Moesegol, gan ddangos eu bod wedi ystyried a datrys materion moesegol sy'n ymwneud â'u prosiect, a'u bod wedi gweithredu arferion gorau priodol ar gyfer gwella atgynyrchioldeb eu hymchwil.
