Poor sleep and high levels of anxiety have a detrimental effect on cognitive functioning. However, very little is known about what cognitive functions are affected by poor sleep or high levels of anxiety and if some are more affected than others. This thesis informs the understanding of poor sleep and anxiety with a focus on generalised anxiety disorder and how they affect specific cognitive functioning namely Attention and Working Memory. Chapter one is a systematic literature review of the qualitative research exploring how sleep deprivation impacts on the cognitive functioning of people with Autistic Spectrum Conditions (ASC) and the principal challenges associated with trying to study the impact of sleep deprivation in people with ASC. Following both database and manual searches, fifteen studies were included and reviewed. The review highlights the suggestions that poor sleep has a detrimental effect on the cognitive functioning of people with ASC. Also, the use of objective and subjective measures of sleep was discussed to help in the early detection of these problems and considerations of carers and families was reviewed. Future research/clinical implications are discussed. Chapter two is a quantitative research study that investigated the combined effects of GAD and poor sleep on Attention and Working Memory. Sleep quality and quantity were assessed using subjective and objective measures of sleep. Attention and Working Memory was measured using various neuropsychological measures. Groups were compared for differences in cognitive scores using a non-parametric test. Relationships between GAD-7 scores, sleep quality/quantity and cognition scores were investigated using correlation analyses. Implications for future research and clinical implications are discussed. Chapter three is a reflective account, exploring the role of reflexivity in personal and professional development during the research process.
