Human temporal perception
The time perception group at Sussex is jointly based in the Department of Informatics and the School of Psychology. We are interested in how humans understand and interact with the temporal aspects of the world. In particular, we want to understand how humans can generate estimates of time, investigating both the cognitive and neural bases. We are also interested in how the bases of time perception are linked with the formation and recall of episodic memory. We are especially interested in how our understanding of these aspects of human experience can be used in the context of digital health technologies and generally in developing human-centred AI.
Beyond time itself, we are also interested in how time perception interacts with other aspects of experience, as expressed in perceived presence and sense of agency, again from both human understanding and AI development perspectives.
We use a combination of behavioural, computational modelling, neuroimaging, and artificial systems approaches to approach these issues. Depending on background, a PhD project might focus on behavioural experiments, developing cognitive models to describe results and make predictions for neuroimaging experiments, or focus more on specifically on model development, with behavioural and/or neuroimaging experiments used as validation. Specific projects we are currently interested in include: determining the contribution of “emotion” to time perception beyond stimulus-driven differences; mapping between model-based, human-annotated, and neuroimaging estimated notions of “event”; developing digital augmentation devices for people with memory impairment. We are also open to student-led proposals.
