Fitness And Action Monitoring: Evidence For Improved Cognitive Flexibility In Young Adults, Jason R. Themanson, Matthew B. Pontifex, Charles H. Hillman

Jason R. Themanson, Ph.D

To improve behavior, one must detect errors and initiate subsequent corrective adaptations. This action monitoring process has been widely studied, but little is known about how one may improve this aspect of cognition. To examine the relationship between cardiorespiratory fitness and action monitoring, we recorded the error-related negativity (ERN), an event-related brain potential believed to index action monitoring, as well as post-error behavioral indices of action monitoring from healthy young adults (18–25 years) who varied in cardiorespiratory fitness. These measures were collected during the execution of flanker tasks emphasizing response accuracy or speed to better assess the specificity of any …

Self-Efficacy Effects On Neuroelectric And Behavioral Indices Of Action Monitoring In Older Adults, Jason R. Themanson, Charles H. Hillman, Edward Mcauley, Sarah M. Buck, Shawna E. Doerksen, Katherine S. Morris, Matthew B. Pontifex

Jason R. Themanson, Ph.D

The relationships between self-efficacy (SE), i.e., beliefs in personal capabilities, and behavioral and neuroelectric (i.e., ERN, Pe) indices of action monitoring were investigated in 40 older adults (13 male) during the completion of a flanker paradigm performed under task conditions emphasizing either accuracy or speed. SE relative to task performance during both conditions was assessed prior to each cognitive task. Results indicated that high-SE older adults exhibited larger ERN and Pe amplitudes compared to low-SE older adults under the accuracy instruction condition. Additionally, a moderating effect of SE on the relationship between ERN and post-error response accuracy was revealed in …

Age And Physical Activity Influences On Action Monitoring During Task Switching, Jason R. Themanson, Charles H. Hillman, John J. Curtin

Jason R. Themanson, Ph.D

Behavioral and neuroelectric indices of action monitoring were compared for 53 high and low physically active older (60–71 years) and younger (18–21 years) adults during a task-switching paradigm in which they performed a task repeatedly or switched between two different tasks. The error-related negativity (ERN) of a response-locked event-related brain potential (ERP) and behavioral measures of response speed and accuracy were measured during the heterogeneous condition (switching randomly between two tasks) of the switch task. Results indicated that older adults exhibited a greater relative slowing in RT during heterogeneous blocks and smaller ERN amplitude compared to younger adults. Additionally, physical …

A History Of Political Experience, Leslie Marsh

Leslie Marsh

This book survives superficial but fails deeper scrutiny. A facile, undiscerning criticism of Lectures in the History of Political Thought (LHPT) is that on Oakeshott’s own account these are lectures on a non-subject: ‘I cannot detect anything which could properly correspond to the expression “the history of political thought”’ (p. 32). This is an entirely typical Oakeshottian swipe – elegant and oblique – at the title of the lecture course he inherited from Harold Laski. If title and quotation sit awkwardly we should remember that Oakeshott never prepared the text for publication – a fortiori he did not prepare it …

Cardiorespiratory Fitness And Acute Aerobic Exercise Effects On Neuroelectric And Behavioral Measures Of Action Monitoring, Jason R. Themanson, Charles H. Hillman

Jason R. Themanson, Ph.D

Cardiorespiratory fitness and acute aerobic exercise effects on cognitive function were assessed for 28 higher- and lower-fit adults during a flanker task by comparing behavioral and neuroelectric indices of action monitoring. The error-related negativity, error positivity, and N2 components, as well as behavioral measures of response speed, accuracy, and post-error slowing were measured following a 30-minute acute bout of treadmill exercise or following 30-minutes of rest. A graded maximal exercise test was used to measure cardiorespiratory fitness by assessing maximal oxygen uptake. Results indicated that higher-fit adults exhibited reduced error-related negativity amplitude, increased error positivity amplitude, and increased post-error response …

Memory Perception And Strategy Use In Parkinson's Disease, Andrew Johnson, Carrie Pollard, Philip Vernon, Jennifer Tomes, Mandar Jog

Andrew M. Johnson

Although there is growing support for the existence of memory deficits within Parkinson's disease (PD), little has been done to evaluate the extent to which PD patients demonstrate differences in their use of metacognitive strategies. In the present study, 79 PD patients (46 men and 33 women) and 49 age-matched healthy participants (19 men and 30 women) were compared on a metamemory questionnaire. PD patients reported significantly less strategy-use than age-matched controls, particularly with regards to external memory strategies (such as making lists). This suggests that auxiliary treatments such as memory strategy training might be effective in this population.

The Report, Beyond the Middle: A Report about Literacy and Numeracy Development of a Target Group Students in the Middle Years of Schooling, provides a useful national coverage of approaches assisting the literacy and numeracy development of Australian students in Years 5 to 10.

The work was undertaken by a research team headed by Professor Allan Luke and Professor John Elkins from the School of Education, University of Queensland and is a study of the efficacy of middle years programmes in all States and Territories for improving teaching and learning, and student outcomes in literacy and numeracy.

The project involved …

A Role Of The Basal Ganglia In Movement: The Effect Of Precues On Discrete Bi-Directional Movements In Parkinson's Disease, Andrew Johnson, Philip Vernon, Quincy Almeida, Linda Grantier, Mandar Jog

Andrew M. Johnson

The effect of a precue on improving movement initiation (i.e., reaction time; RT) is well understood, whereas its influence on movement execution (i.e., movement time; MT) has rarely been examined. The current study investigated the influence of a directional precue (i.e., left vs. right) on the RT and MT of simple and discrete bi-directional movements in a large sample of Parkinson's disease patients and healthy control participants. Both patients and controls were tested twice, with testing sessions separated by 2 hours. Patients were tested first following an overnight levodopa withdrawal and again after they had taken their medication. Both patients …

Age And Neuropsychological Status Following Exposure To Violent Nonimpact Acceleration Forces In Mvas, James Sweeney, Andrew Johnson

Andrew M. Johnson

Performance on the Halstead-ReitanNeuropsychological Test Battery (HRB) was analyzed for 33 ind viduals, aged 20 to 69, who had been subjected to violent aceeleration forces in motor vehicle accidents . Age was considered as a continuous variable and correlated with single and compos ite HRB measures. With the one exception of the Left Neuropsychological Deficit Scale (NDS) score, agere lated de cline was consistently demonstrated by com positeHRB scores (i.e., Gen eralNDS, Right NDS, Level of Performance NDS, Pathognomonic SignNDS, Pattern NDS, Right-Left Differ enceNDS, and Halstead Impairment Index). In contrast, most single non-composite HRB measures did not refleet a …
