About this Lecture


In this lecture, we think about how studying patients with brain damage can help researchers to better understand memory, focusing in particular on: (i) Henry Molaison (HM) as one of the most famous patients in history, who suffered brain damage as a teenager; (ii) the operation HM underwent to remove the medial temporal lobes, which were the source of his acquired epilepsy; (iii) the resulting memory damage, which led him to lay down no further long term memories after the operation; (iv) Atkinson and Shiffrin’s multi-store model of memory, differentiating short- and long-term memory; (v) the phenomenon that HM was able to learn and remember skills, demonstrated by the mirror drawing task, despite not remembering that he had performed the task before; (vi) research into HM, which uncovered the distinction between procedural and declarative memory, further dividing declarative memory into episodic and semantic memory; (vii) three proposed questions, which all address different forms of memory.


In this course, Dr Ashok Jansari (Goldsmiths, University of London) explores the processes of remembering and forgetting. In the first lecture, we think about what memory is and how it can be conceptualised. In the second lecture, we think about some key individual differences in memory performance, including the impacts of physical and emotional states. In the third lecture, we think about how studying individuals with specific, acquired brain damage can help researchers better understand memory. Next, we think about amnesia, both in healthy ageing and through neurodegenerative disorders. In the fifth and final lecture, we think about some current research in the field of memory.


Dr Ashok Jansari is a senior lecturer in the Department of Psychology at Goldsmiths, University of London. Dr Jansari’s research interests include memory disorders, prosopagnosia, executive functions, and synaesthesia. Dr Jansari is most famous for his research into prosopagnosia, having made numerous TV appearances, including on BBC1’s The One Show, as well as hosting his own ‘Neuro Talk’ YouTube channel:

Some of Dr Jansari's recent publications include 'Acquired synaesthesia following 2C-B use' (2019), 'Using virtual reality to investigate multitasking ability in individuals with frontal lobe lesions' (2019), and 'Identification from CCTV: Assessing police super-recogniser ability to spot faces in a crown and susceptibility to change blindness' (2018).
