Research
Dr Jessica Brough
During my Masters and my PhD, I studied descriptions of interactions at the University of Edinburgh, with children and adults. My research interests include social biases of mention order, developmental psycholinguistics, perceptions of agency, animacy and social robotics. During my PhD, I received supervision from Prof Hugh Rabagliati and Prof Holly Branigan at UoE and Prof Lasana Harris at UCL.
The first paper from my PhD thesis, Cognitive causes of ‘like me’ race and gender biases in human language production, is out in Nature Human Behaviour.

Research areas
Mention order
What can first mention, the entity mentioned first in an utterance, tell us about group identification, self-other equivalences and assumptions of agency? In the field of psycholinguistics, language is not routinely studied in relation to social identity or social contexts. Yet, language is a fundamental social behaviour that is often influenced by culture and society. Through a series of production experiments, my thesis showed that a speaker who is describing an interaction such as a hug taking place between someone from their ingroup and someone from their outgroup will demonstrate a tendency to mention the ingroup member first.
Judgements of agency
Who a listener hears first in an utterance influences semantic inferences. In addition to studying mention order in language production, my thesis also investigated the effects of mention order on judgements of agency. If you hear “Kate is hugging Beth”, who do you suspect instigated the hug? First-mention agency biases have important implications for how we conceptualise a host of behaviours, including responsibility, victimhood and aggression.
Animacy
Animacy is a multi-faceted concept, distinguishing humans from other living things, and living things from inanimate objects or concepts. In my thesis, I explored what makes an entity animate, and how flexible (or inflexible) this qualifier can be, using theories such as conceptual accessibility and mind perception to inform my work. I studied how perceptions of animacy influence descriptions of interactions between a more animate and a less animate entity, pairing humans with social robots and manipulating how speakers perceive their relative humanness.
