Kelsey Perrykkad

Kelsey Perrykkad (previously Palghat) has an interdisciplinary background, working between cognitive science and philosophy. She is a Post Doctoral Research Fellow in the Cognition and Philosophy Lab.

Kelsey studies how people act in the world to learn about who they are, and in turn, how one’s self-representation influences behaviour and wellbeing. She investigates self-representation in various mental health conditions (e.g. autism), at key developmental points in the lifespan (e.g. pregnancy), and how features of self-representation correlate with real-world behaviour (e.g. charitable donation).

Kelsey's PhD was conferred in mid-2021, and conducted in the lab under the primary supervision of Jakob Hohwy along with secondary supervisor Sharna Jamadar. Titled Self in Autism: A Predictive Perspective, the project was about how putting together predictive processing theories of the self and autism spectrum conditions might lead us to better understand self-cognition in autism. She primarily used eye-tracking and behavioural measures in a judgement of agency task, along with other theoretical and experimental projects.

Before starting her PhD at Monash, Kelsey worked at the Queensland Brain Institute as a Senior Research Assistant and the EEG lab manager. There, she studied the sense of agency, the intersection between education and neuroscience in real classrooms (with the SLRC) and neural correlates of motor preparation in naturalistic movements. She simultaneously worked for the Autism CRC, as a Senior Research Officer under the Classroom Acoustics Project , which tested the efficacy of sound field systems in improving the classroom environment for autistic children. She has also worked as a research assistant at Occidental College, where she helped develop novel pedagogical methods and worked on a project about the ethical, social and legal implications of the human genome project.
