About this Lecture


In this lecture, we think about memory and amnesia, focusing in particular on: (i) the challenges of creating clinical tests for memory with the correct level and type of sensitivity; (ii) accelerated long-term forgetting as a memory condition wherein sufferers do not forget things immediately, but they do forget them faster than is typical; (iii) accelerated long-term forgetting being characterised not by an inability to form memories, like HM’s form of forgetting, but an inability to maintain those connections within memory over time; (iv) Verbal Associative Learning and Memory Test (VALMT), developed to detect memory problems like accelerated long-term forgetting; (v) the challenge of differentiating forgetting due to healthy ageing and forgetting due to a neurodegenerative disorder like dementia, because of large individual differences in memory performance and degradation; (vi) the ability of VALMT to pick up pre-clinical signatures of dementia; (vii) research into the field of chronic traumatic encephalopathy, characterised by repeated, sub-concussive head injuries, typically associated with playing contact sports; (viii) current research into the hormonal system changes during the perimenopause and menopause, leading to memory problems.


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).
