Beth Jefferies



Beth Jefferies completed an MA in Experimental Psychology at the University of Oxford and a PhD in Neuropsychology at the University of Bristol. She then moved to the University of Manchester in 2003, where she worked as an RCUK Research Fellow investigating disorders of semantic cognition and language following stroke and dementia. During these years, she started to use complementary neuroscientific methods (transcranial magnetic stimulation; functional neuroimaging) to investigate hypotheses about the neural basis of semantic cognition and language that emerged from the ongoing patient studies. In 2007, she moved to the Department of Psychology at the University of York.

Beth currently holds grants from BBSRC, ERC and Stroke Association which employ multiple methods to explore the neural basis of semantic cognition and conceptual-linguistic interactions, including the evolution of cortical processing over time (using magnetoencephalography). A new project is also using electrical stimulation (tDCS) to explore the potential for improved rehabilitation of acquired disorders of semantics and language, building on Beth’s previous work that examined the underlying cause of semantic deficits in different patient groups.

Neural basis of semantic memory

We are investigating the nature of the semantic impairment in patients with different aetiologies and brain lesions to examine the neural networks underpinning (i) conceptual knowledge of words, sounds and pictures and (ii) control processes that regulate semantic processing.

We also use fMRI and transcranial magnetic stimulation (TMS) in healthy participants to provide convergent evidence and to extend our patient findings. Our results argue for a revised model of semantic cognition, in which brain regions beyond left inferior frontal cortex contribute to semantic control.

Semantic binding in phonological processing

Our studies of patients with semantic dementia and healthy volunteers suggest that word meaning contributes to phonological coherence. When semantic binding is weak, phonological errors such as spoonerisms (e.g., “dart, hog” produced as “heart, dog”) become more frequent in verbal short-term memory and other tasks like paced reading that require rapid serial production. These findings help to constrain models of the interaction between phonology and semantics.
