Cognitive And Neuroscientific Perspectives Of Healthy Ageing, Jon B. Prince, Helen L. Davis, Jane Tan, Katrina Muller-Townsend, Shaun Markovic, David M. G. Lewis, Brianne Hastie, Matthew B. Thompson, Peter D. Drummond, Hakuei Fujiyama, Hamid R. Sohrabi

Research outputs 2022 to 2026

With dementia incidence projected to escalate significantly within the next 25 years, the United Nations declared 2021–2030 the Decade of Healthy Ageing, emphasising cognition as a crucial element. As a leading discipline in cognition and ageing research, psychology is well-equipped to offer insights for translational research, clinical practice, and policy-making. In this comprehensive review, we discuss the current state of knowledge on age-related changes in cognition and psychological health. We discuss cognitive changes during ageing, including (a) heterogeneity in the rate, trajectory, and characteristics of decline experienced by older adults, (b) the role of cognitive reserve in age-related cognitive decline, …

The Effect Of Acute Exercise On Objectively Measured Sleep And Cognition In Older Adults, Kelsey R. Sewell, Nathan D. W. Smith, Stephanie R. Rainey-Smith, Jeremiah Peiffer, Hamid R. Sohrabi, Kirk I. Erickson, Belinda M. Brown

Research outputs 2022 to 2026

Background: Exercise can improve cognition in aging, however it is unclear how exercise influences cognition, and sleep may partially explain this association. The current study aimed to investigate whether objectively measured sleep mediates the effect of an acute exercise intervention on cognition in older adults. Methods: Participants were 30 cognitively unimpaired, physically active older adults (69.2 ± 4.3 years) with poor sleep (determined via self-report). After a triple baseline cognitive assessment to account for any natural fluctuation in cognitive performance, participants completed either a single bout of 20-minutes of high intensity exercise on a cycle ergometer, or a control condition, …

ABSTRACT: Coyne, JOC, Coutts, AJ, Newton, RU, and Haff, GG. The influence of mental fatigue on sessional ratings of perceived exertion in elite open and closed skill sports athletes. J Strength Cond Res 35(4): 963-969, 2021-The main purpose of this investigation was to examine influence of mental fatigue on sessional ratings of perceived exertion (sRPE) over a training week in elite athletes in open skill (OS, i.e., more unpredictable and externally paced sports) and closed skill (CS, i.e., more predictable and internally paced) sports. Visual analogue scales for mental fatigue, sRPE (CR-10 scale), and training duration were collected from an …


A Novel Approach To Measure Executive Functions In Students: An Evaluation Of Two Child-Friendly Apps, Valeska Berg, Shane Rogers, Mark Mcmahon, Michael Garrett, Dominic Manley Jan 2020

A Novel Approach To Measure Executive Functions In Students: An Evaluation Of Two Child-Friendly Apps, Valeska Berg, Shane Rogers, Mark Mcmahon, Michael Garrett, Dominic Manley

Research outputs 2014 to 2021

Interest in measurement of children’s executive functions has shown a major increase over the past two decades. The present study evaluates two new apps (EYT and eFun) for measuring executive functions in children. The results of this study show that children (aged 5–8) enjoy executive function assessment in the form of games on an iPad. However, only one executive function, EYT working memory, showed significant positive correlations with several types of grades (e.g., English and maths) in primary school students. New, self-assessed, child-friendly executive function measurement tools have the potential to provide future possibilities for teachers to integrate information on …


Effects Of Long-Term Participation In Tennis On Cognitive Function In Elderly Individuals, Scott Culpin Jan 2018

Effects Of Long-Term Participation In Tennis On Cognitive Function In Elderly Individuals, Scott Culpin

Theses: Doctorates and Masters

Many studies have reported the relationship between exercise and cognition with conflicting results. This may be due to differences in intervention durations, session lengths, intensities, and type of exercise. It has been suggested that exercises requiring greater cognitive demand such as football, basketball and racquet sports, are protective against cognitive decline, compared to less cognitively demanding exercises such as swimming, cycling and running, however, research concerning exercise types are currently limited. The present study tested the hypothesis that elderly individuals who had been regularly playing tennis more than 10 years, would have greater cognitive function than those who had been …


The Relationship Between Physical Exercise And Cognition In Children With Typical Development And Neurodevelopmental Disorders, Beron Wei Zhong Tan Jan 2017

The Relationship Between Physical Exercise And Cognition In Children With Typical Development And Neurodevelopmental Disorders, Beron Wei Zhong Tan

Theses: Doctorates and Masters

This research project sought to investigate the relationship between physical exercise and cognition in children with and without a neurodevelopmental condition. To achieve this aim, three approaches were undertaken to explore the exercise and cognition relationship. The first approach sought to understand the efficacy of exercise interventions on cognition in individuals with a neurodevelopmental disorder. The second approach was to understand the effectiveness of an exercise activity when compared to a cognitively-engaging tablet game activity on measures of implicit learning and attention in children with and without a neurodevelopmental condition. The third approach was to investigate if psychophysiological measures could …


The Role Of Awareness Of Repetition During The Development Of Automaticity, Emma Shadbolt Jan 2015

The Role Of Awareness Of Repetition During The Development Of Automaticity, Emma Shadbolt

Theses : Honours

Investigation into the influence of contextual information on performance of an automatic task has found inconsistent results. The majority of studies have investigated whether changing the context of a simple cognitive task can inhibit an automatic response, but do not review whether context can help the development of automatic responding. The current study examined whether bringing awareness to the context of a simple numerosity task could aid the development of automaticity. It also examined whether participants were aware of when automaticity developed for them via a post-test interview. The numerosity task used in this study was a simple counting task …


How Mean Is The Mean?, Craig P. Speelman, Marek Mcgann Jan 2013

How Mean Is The Mean?, Craig P. Speelman, Marek Mcgann

Research outputs 2013

In this paper we voice concerns about the uncritical manner in which the mean is often used as a summary statistic in psychological research. We identify a number of implicit assumptions underlying the use of the mean and argue that the fragility of these assumptions should be more carefully considered. We examine some of the ways in which the potential violation of these assumptions can lead us into significant theoretical and methodological error. Illustrations of alternative models of research already extant within Psychology are used to explore methods of research less mean-dependent and suggest that a critical assessment of the …


Visual Memory Improvement In Recognition, Allison Prandl Jan 2012

Visual Memory Improvement In Recognition, Allison Prandl

Theses : Honours

Fluid intelligence and working memory has been improved by training on a visual working memory n-back task (Jaeggi, Buschkuehl, Jonides & Perrig, 2008). The present study investigated whether n-back training can improve visual memory using a test of visual recognition. A sample of 47 participants were trained for 20 days on either the single n-back task (n = 26) or a general knowledge and vocabulary task (n = 21). The results showed that training using the single n-back task did not significantly increase scores on a test of visual recognition when compared with general knowledge and vocabulary training. However, when …


Improving Memory Using N-Back Training, Paul Beavon Jan 2012

Improving Memory Using N-Back Training, Paul Beavon

Theses : Honours

Investigations into n-back training and near transfer to short-term memory (STM) and working memory (WM) have realised inconsistent results. A significant transfer to STM was reported using dual n-back training (Jaeggi, Buschkuehl, Jonides, & Perrig, 2008). However, the majority of studies have found no significant transfer to WM as operationalised by complex span tasks using either single or dual n-back training. The current study examined the single n-back task and near transfer to STM and WM as operationalised by the Woodcock-Johnson III Tests of Cognitive Abilities (Mather & Woodcock-Johnson, 2001). Forty-seven participants were divided into experimental treatment (n = 26) …


Short Term Effects Of Repeated Masked Priming In Stem Completion Tasks, Anthony Van Andel Jan 1995

Short Term Effects Of Repeated Masked Priming In Stem Completion Tasks, Anthony Van Andel

Theses : Honours

This thesis examines the effect of time delay and intervening items on masked repetition studies with word stem completion tasks. In the first experiment a masked priming effect was obtained. The effect was strongest 500ms after the presentation of the prime, and decreasing in a linear trend seven seconds after the presentation of the prime. The second experiment found that interpolating a naming task between the masked prime and the stem completion task eliminated the effects of the repeated masked prime. This result is a failure to replicate previous research which found a masked repetition effect over a short delay …
