Overview

What is he best known for?

The fields of study he is best known for:

  • Cognition
  • Developmental psychology
  • Internal medicine

Developmental psychology, Cognition, Longitudinal study, Cognitive psychology and Effects of sleep deprivation on cognitive performance are his primary areas of study. His Developmental psychology research incorporates themes from Metamemory, Working memory, Stroop effect, Verbal fluency test and Structural equation modeling. His Cognition research integrates issues from Social psychology, Age differences and Cognitive decline.

His studies in Longitudinal study integrate themes in fields like Cognitive skill, Follow up studies, Personality and Adult development. His studies examine the connections between Cognitive psychology and genetics, as well as such issues in Cognitive aging, with regards to Cognitive neuroscience. His Effects of sleep deprivation on cognitive performance research is multidisciplinary, incorporating elements of Young adult, Demography and Cognitive change.

His most cited work include:

  • Use it or lose it: Engaged lifestyle as a buffer of cognitive decline in aging? (718 citations)
  • Variability in Reaction Time Performance of Younger and Older Adults (547 citations)
  • Measurement properties of the Center for Epidemiological Studies Depression Scale (CES-D) in older populations. (415 citations)

What are the main themes of his work throughout his whole career to date?

The scientist’s investigation covers issues in Developmental psychology, Cognition, Longitudinal study, Cognitive psychology and Gerontology. He is involved in the study of Developmental psychology that focuses on Psychometrics in particular. His research ties Cognitive decline and Cognition together.

The various areas that Roger A. Dixon examines in his Longitudinal study study include Demography, Moderation, Clinical psychology, Neurocognitive and Latent growth modeling. His Cognitive psychology study combines topics in areas such as Compensation and Cognitive aging. In Gerontology, Roger A. Dixon works on issues like Apolipoprotein E, which are connected to Genetic risk and Oncology.

He most often published in these fields:

  • Developmental psychology (47.92%)
  • Cognition (43.75%)
  • Longitudinal study (25.52%)

What were the highlights of his more recent work (between 2016-2021)?

  • Cognition (43.75%)
  • Dementia (10.42%)
  • Longitudinal study (25.52%)

In recent papers he was focusing on the following fields of study:

Roger A. Dixon mainly investigates Cognition, Dementia, Longitudinal study, Disease and Apolipoprotein E. His work deals with themes such as Gait, Gait, Preferred walking speed, Proxy and Cognitive decline, which intersect with Cognition. Roger A. Dixon has researched Cognitive decline in several fields, including Meta-analysis, Neurocognitive, Cognitive skill and Clinical trial.

His Dementia research includes themes of Demography, Representativeness heuristic, Oncology and Episodic memory. The study incorporates disciplines such as Logistic regression, Gerontology, Neuropsychology, Clinical psychology and Latent growth modeling in addition to Longitudinal study. Roger A. Dixon combines subjects such as Neuroscience and Moderation with his study of Apolipoprotein E.

Between 2016 and 2021, his most popular works were:

  • Investigation of antihypertensive class, dementia, and cognitive decline: A meta-analysis (36 citations)
  • Profiling novel metabolic biomarkers for Parkinson's disease using in-depth metabolomic analysis. (32 citations)
  • Executive function performance and change in aging is predicted by apolipoprotein E, intensified by catechol-O-methyltransferase and brain-derived neurotrophic factor, and moderated by age and lifestyle (19 citations)

In his most recent research, the most cited papers focused on:

  • Cognition
  • Internal medicine
  • Social psychology

Roger A. Dixon mostly deals with Cognition, Dementia, Internal medicine, Metabolomics and Gerontology. His Cognition research is multidisciplinary, incorporating perspectives in Longitudinal study, Apolipoprotein E and Cognitive decline. His work in the fields of Dementia, such as Dementia research and Mild memory loss, intersects with other areas such as CCNA and Hogan.

His Internal medicine study combines topics from a wide range of disciplines, such as Liquid chromatography–mass spectrometry, Oncology, Metabolic biomarkers and Pathology. Roger A. Dixon works mostly in the field of Metabolomics, limiting it down to topics relating to Disease and, in certain cases, Neuroimaging and Computational biology, as a part of the same area of interest. His work carried out in the field of Gerontology brings together such families of science as Meta-analysis, Clinical trial and Cohort.
