Neuroscience of socioeconomic status and poverty: Is it actionable?
SES neuroscience, using imaging and other methods, has revealed generalizations of interest for population neuroscience and the study of individual differences. But beyond its scientific interest, SES is a topic of societal importance. Does neuroscience offer any useful insights for promoting socioeconomic justice and reducing the harms of poverty? In this talk I will use research from my own lab and others’ to argue that SES neuroscience has the potential to contribute to policy in this area, although its application is premature at present. I will also attempt to forecast the ways in which practical solutions to the problems of poverty may emerge from SES neuroscience. Bio: Martha Farah has conducted groundbreaking research on face and object recognition, visual attention, mental imagery, and semantic memory and - in more recent times - has been at the forefront of interdisciplinary research into neuroscience and society. This deals with topics such as using fMRI for lie detection, ethics of cognitive enhancement, and effects of social deprivation on brain development.
Social deprivation, coping and drugs: a bad cocktail in the COVID-19 era: evidence from preclinical studies
The factors that underlie an individual’s vulnerability to switch from controlled, recreational drug use to addiction are not well understood. I will discuss the evidence in rats that in individuals housed in enriched conditions, the experience of drugs in the relative social and sensory impoverishment of the drug taking context, and the associated change in behavioural traits of resilience to addiction, exacerbate the vulnerability to develop compulsive drug intake. I will further discuss the importance of the acquisition of alcohol drinking as a mechanism to cope with distress as a factor of exacerbated vulnerability to develop compulsive alcohol intake. Together these results demonstrate that experiential factors in the drug taking context, which can be substantially driven by social isolation, shape the vulnerability to addiction.
Development of the social brain in adolescence and effects of social distancing
Adolescence is a period of life characterised by heightened sensitivity to social stimuli, an increased need for peer interaction and peer acceptance, and development of the social brain. Lockdown and social distancing measures intended to mitigate the spread of COVID-19 are reducing the opportunity to engage in face-to-face social interaction with peers. The consequences of social distancing on human social brain and social cognitive development are unknown, but animal research has shown that social deprivation and isolation have unique effects on brain and behaviour in adolescence compared with other stages of life. It is possible that social distancing might have a disproportionate effect on an age group for whom peer interaction is a vital aspect of development.
