About this Lecture


In this lecture, we think about delayed gratification, focusing in particular on: (i) the 2011 study by Casey, which followed up on participants who completed a delayed gratification study as infants, 40 years later; (ii) the findings that those who expressed the ability to delay gratification as children maintained that ability into adulthood; (iii) the physical differences in brain circuitry in the frontal lobes, discovered using fMRI scans, between those who were and were not able to delay gratification.


In this course, Dr Ashok Jansari (Goldsmiths, University of London) explores the layout and function of the brain from a biopsychological perspective. In the first lecture, we think about how the nervous system transcodes sensory input into electrical signals that can be processed in the brain. In the second lecture, we think about how different areas of the brain are specialised to perform certain functions, and some of the early research which led to these discoveries. In the third lecture, we think about the different techniques used to generate images of brain structure and activity. Next, we think about how internal and external cues can influence our biological rhythms. In the fifth and final lecture, we think about the role of longitudinal research and brain imaging in understanding how behaviour consistency and change can be represented by physical brain structure differences, contextualised in a study on delayed gratification.


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).
