My research looks at children’s pragmatic abilities, i.e. how children understand meaning beyond vocabulary and grammar. I investigate how children make choices about how to refer to objects, for example, do they say the spotty dog, the dog, or he to introduce a character in a story? Why does this differ from what adults do? Do they first look at all objects in a scene before describing a specific object, or do they disregard them? How do they work out how much detail to provide in their referring expressions?

One of my current projects focuses on how children understand and process adjectives – a common but challenging category of words. I’m also investigating children’s inferencing ability and whether it can be improved by increased exposure to inferential talk during shared bookreading.

I study language development in monolingual and bilingual children, and seek to understand how it interacts with their cognitive development. Some of the questions I seek to address include:

  • From what age do children master the linguistic rules underlying the exchange of information? How does their cognitive development interact with their linguistic development in that respect?
  • How does the amount of bilingual experience of a child affect their proficiency in the language of schooling?
  • How do bilingual experience and socio-economic factors affect children’s cognitive development

I am a developmental psychologist interested in the factors that affect how children learn to read, these include spoken language skills, working memory, sleep and whether a child has a neurodevelopmental disorder, such as a specific language impairment, dyslexia, attention deficit hyperactivity disorder and narcolepsy.  My current research includes the Paediatric Narcolepsy Project, a behavioural intervention for sleep problems in children with ADHD and a White Rose DTC ESRC Network (2015 – 2018) for understanding and enhancing reading and language skills in children for whom English is an additional language.

I am a linguist currently working as a post-doctoral research assistant on the Q-BEx project. My previous research focused on child bilingualism, cognition (executive functions and the Theory of Mind), figurative language (idioms and metaphors), autistic-like traits, and autism spectrum disorders. My other areas of interest include code-switching, pragmatic language development, language processing, and language impairment.

I graduated with a BA from Gazi University (Ankara, Turkey) in Special Education in 2015, passing my Masters degree in the same field in 2018.  I am currently a PhD researcher in School of Education, investigating the effectiveness of a dialogic reading intervention on the language and early literacy development of children in Turkey. My supervisors are Dr Paula Clarke (Education), Dr Hannah Nash (Psychology) and Dr Cat Davies (Linguistics). My PhD research investigates the impact of a parent-delivered dialogic reading program targeting phonological awareness, vocabulary knowledge, letter knowledge, print awareness, listening comprehension, and reading attitudes in Turkish preschool children whose language development may be at risk due to their socioeconomic background.

I am a PhD researcher in the School of Psychology looking at sleep and its impact on the daytime functioning, academic attainment, cognitive development and well-being in children with ADHD. My project is supervised by Dr Hannah Nash and Dr Ian Kellar from the University of Leeds and Professor Heather Elphick from The Sheffield Children’s Hospital.

Dr Jamie Lingwood

Jamie is a researcher interested in how the quality of the input that children experience relates to how they learn language. His research is broadly focused on how we can design, implement and evaluate evidence-based interventions to foster children’s language development. He works with caregivers and children from a range of socioeconomic backgrounds. Since 2018 Jamie has been working on an ESRC project with Dr Cat Davies in which they investigated how children experience, understand, and use adjectives. Using eyetracking experiments, corpus analyses, and a randomised controlled trial, the project focused how children’s socioeconomic background might affect their descriptive language abilities.

Bissera finished her BA in Linguistics and Phonetics at Leeds in 2013 with a theoretical dissertation discussing metaphor processing, then went on to do an MSc in Cognitive and Decision Sciences at UCL. Her research interests are in language processing and acquisition, especially in the wider context of cognitive and emotional processing and development. Bissera worked with Cat Davies and Jamie Lingwood on children’s processing of adjectives in 2019/20.

Annika spent Spring 2019 at the LCDU on an internship during her Masters in Linguistics at the University of Groningen. She worked with Cat Davies and Jamie Lingwood on children’s processing of adjectives in 2019.

Rachael passed her Masters by Research in 2018. Her thesis investigated the features of child-directed speech used with children diagnosed with Autism Spectrum Disorder (ASD). The project was supervised by Cat Daves and Cecile De Cat.
