Claire completed her undergraduate study in psychology at the University of Wollongong, where her interest in cognitive science began to develop. Claire has a background in experimental psychology, working within the domain of memory. She is currently completing a Master of Clinical Neuropsychology which has led to a special interest in dementia. Witnessing the effect neurodegenerative processes have on patients and their families has fed Claire’s deep motivation and passion about dementia research.
Claire assists the Anstey group as a Data Manager. She is interested in research integrity, reproducibility and open science. She is passionate about implementing effective data management to support and streamline the research process and enjoys the opportunity to engage with research that has widespread impact on our understanding of dementia.
The Personality and Total Health (PATH) Through Life Project is a large on-going population-based longitudinal cohort study comprising approximately 7500 participants. The first wave of data collection occurred in 1999 and included young (aged 20–24 at baseline), midlife (aged 40–44 at baseline) and older (aged 60–64 at baseline) adults randomly sampled from the electoral roll of the ACT and the nearby city of Queanbeyan. Additional waves of data collection have occurred in 4-year increments, with wave 5 of data collection beginning in 2018.
The broad aims of the PATH study relate to clinical outcomes that constitute the major burden of disease within the Australian community.
Primary PATH Objectives:
Several design features of the PATH project contribute to its unique standing among population-based longitudinal cohort studies.
This project has been funded primarily by the National Health and Medical Research Council. Wave 5 40s and 60s follow-ups will be funded by the ARC Centre of Research Excellence in Population Ageing.

In serial recall tasks, presenting items in alternating female and male voices impairs performance relative to the single-voice presentation. This phenomenon, termed the talker-variability effect (TVE), was recently reexamined by Hughes, Marsh, and Jones (2009, 2011), who used the effect as confirmatory evidence for their perceptual-gestural account of serial recall performance. Despite the authors' claim of generalisability, the serial recall paradigm employed did not reflect the standard parameters more generally adopted in verbal short-term memory research. Specifically, the presentation rate of the stimuli was almost 3 times that typically used. We sought to determine if the TVE, as observed by Hughes et al., was generalisable to the standard serial recall task by directly comparing recall performance in talker-variable conditions at fast and slow stimulus presentation rates. Experiment 1 employed a systematic replication of the foundational study undertaken by Hughes et al. (2009). Utilising a novel stimulus set, Experiment 2 provided a subsequent test of the generalisability of the TVE, examining the influence of item properties. Both experiments showed a robust TVE at the atypical fast presentation rate; however, for the slower item presentation, the TVE was unreliable. Furthermore, error analysis suggests that item recall also contributes to the TVE, contrary to the current explanation proposed by Hughes et al. (2009, 2011). The challenge of the present data to the perceptual-gestural account of the TVE is explored. Alternative accounts that focus on the resource cost of categorical speech perception in the context of talker variability are posited.
