White Matter Connectome Associations With Reading Functions In Children, Chenglin Lou
White Matter Connectome Associations With Reading Functions In Children, Chenglin Lou
Electronic Thesis and Dissertation Repository
This thesis investigated associations between the white matter connectome and reading in children with a wide range of reading abilities. It is well established that the connectome supports the interplay among brain regions and connections within an integrated system. In this dissertation, I examine the hypothesis that it could therefore represent multiple mapping processes among reading components and further explain variations in reading performance. Such associations between the organization of the connectome and reading skills have not been well explored. This thesis aimed to address this issue by considering both the relationship between connectome measures and standardized reading performance out …
Examining The Relationships Between Socio-Cognitive Factors And Neural Synchrony During Movie Watching Across Development, Kathleen M. Lyons
Examining The Relationships Between Socio-Cognitive Factors And Neural Synchrony During Movie Watching Across Development, Kathleen M. Lyons
Electronic Thesis and Dissertation Repository
While different cognitive abilities mature, the conscious experiences of children likely become richer and more elaborate. A challenge in investigating relationships between cognitive development and real-world experiences is having measures that assess naturalistic processing. Movie watching offers a solution, since following the plot of a film requires cognitive processes that are similar to real-world experiences. When different adults watch the same film, their brain activity begins to align (known as neural synchrony). The strength of this alignment has been shown to reflect the degree to which different individuals are having a similar experience of the movie. While this phenomenon has …
Cognitive, Neural, And Educational Contributions To Mathematics Performance: A Closer Look At The Roles Of Numerical And Spatial Skills, Zachary C.K. Hawes
Cognitive, Neural, And Educational Contributions To Mathematics Performance: A Closer Look At The Roles Of Numerical And Spatial Skills, Zachary C.K. Hawes
Electronic Thesis and Dissertation Repository
The principal aims of this thesis were to (1) provide new insights into the cognitive and neural associations between spatial and mathematical abilities, and (2) translate and apply findings from the field of numerical cognition to the teaching and learning of early mathematics.
Study 1 investigated the structure and interrelations amongst cognitive constructs related to numerical, spatial, and executive function (EF) skills and mathematics achievement in 4- to 11-year old children (N=316). Results revealed evidence of highly related, yet separable, cognitive constructs. Together, numerical, spatial, and EF skills explained 84% of the variance in mathematics achievement (controlling for chronological age). …
The Neurocognitive Underpinnings Of Arithmetic In Children And Adults: Examining The Roles Of Domain General And Domain Specific Abilities, Anna A. Matejko
The Neurocognitive Underpinnings Of Arithmetic In Children And Adults: Examining The Roles Of Domain General And Domain Specific Abilities, Anna A. Matejko
Electronic Thesis and Dissertation Repository
What are the cognitive underpinnings of arithmetic and how do they contribute to individual differences in children’s calculation abilities? Behavioural research has provided insights into which domain general (e.g. working memory) and domain specific (e.g. symbol-quantity associations) competencies are important for the acquisition of arithmetic skills. However, how domain general and domain specific skills are related to arithmetic at the neural level remains unclear. This thesis investigates the interplay between arithmetic and both domain general and specific competencies in the brain.
In Chapter 2 I examine how visuo-spatial working memory (VSWM) networks overlap with those for arithmetic in children and …
Interactions Between The Basolateral Amygdala And Ventral Striatum During Probabilistic Learning In Children And Associations With Individual Differences In Free Cortisol, Haley J. Fallowfield
Interactions Between The Basolateral Amygdala And Ventral Striatum During Probabilistic Learning In Children And Associations With Individual Differences In Free Cortisol, Haley J. Fallowfield
Electronic Thesis and Dissertation Repository
Stress can drastically alter the behavioural and functional correlates of feedback learning; however, the functional correlates of these effects are poorly understood, particularly in children. In the present study, typically developing children between the ages of 9- and 11-years-old completed a probabilistic learning task with both appetitive and aversive outcomes in a magnetic resonance imaging scanner. Anticipatory stress to the experimental environment was measured via salivary cortisol at baseline and prior to completion of the task. Although baseline and pre-MRI cortisol values were not reliably different at the group level, subsequent analyses revealed that the basolateral amygdala was less responsive …
Cortical Representation Underlying The Semantic Processing Of Numerical Symbols: Evidence From Adult And Developmental Studies, Stephan Erich Vogel
Cortical Representation Underlying The Semantic Processing Of Numerical Symbols: Evidence From Adult And Developmental Studies, Stephan Erich Vogel
Electronic Thesis and Dissertation Repository
Humans possess the remarkable ability to process numerical information using numerical symbols such as Arabic digits. A growing body of neuroimaging work has provided new insights into the neural correlates associated with symbolic numerical magnitude processing. However, little is known about the cortical specialization underlying the representation of symbolic numerical magnitude in adults and children. To constrain our current knowledge, I conducted a series of functional Magnetic Resonance Imaging (fMRI) studies that aimed to better understand the functional specialization of symbolic numerical magnitudes representation in the human brain.
Using a number line estimation task, the first study contrasted the brain …
