Welcome to Lyndsey Nickels' personal web page

My research interest can broadly be described as the cognitive neuropsychology of language. Much of this research has focused on spoken word production and its remediation in aphasia. However, more recently this has extended to acquired and developmental disorders of reading and spelling with, once again, an interest in how best to remediate these disorders.

• recent publications (some with downloads of reprints and preprints)
• a selection of other downloads - conferences/talks & a model of language processing.

Note: Some preprints contain phonetic fonts, to ensure that these are legible you will need to install silipa93.exe
