Morphometric dissimilarity in association cortices linked to autism subtype with more severe symptoms

Hongxiu Jiang, Raul Rodriguez-Cruces, Ke Xie, Valeria Kebets et autres

• MSN-based clustering revealed three neuroanatomical subtypes in individuals with ASD. • Subtype with weaker MSN values in frontal temporal association regions exhibited more ASD symptoms. • Distinct functional hyperconnectivity patterns were observed across subtypes, involving salience, default, language, and visual networks. …

Understanding the role of the default mode network in episodic memory, theory-of-mind, and self-referencing in typical and atypical development

Hilary Sweatman

This thesis investigates the developmental specialization of brain networks supporting self-processing, theory of mind (ToM), and episodic memory, with a particular focus on the default mode network (DMN). Across a series of studies using naturalistic paradigms and precision neuroimaging, we show that …

Epistemic Fragility in Large Language Models: Prompt Framing Systematically Modulates Misinformation Correction

Sekoul Krastev, Hilary Sweatman, Anni Sternisko, Steve Rathje

As large language models (LLMs) rapidly displace traditional expertise, their capacity to correct misinformation has become a core concern. We investigate the idea that prompt framing systematically modulates misinformation correction - something we term 'epistemic fragility'. We manipulated prompts by open-mindedness, user …

Self-referential encoding in the developing brain

Hilary Sweatman, Ying He, Ross Lawrence, Xiaoqian J. Chai

Episodic memory is closely linked to the self and information related to the self tends to be better remembered. In adults, the brain's default mode network (DMN) supports self-referential thought and memory, with the medial prefrontal cortex (mPFC) being important for both …

Regional Excitatory–Inhibitory Balance Relates to Self-Reference Effect on Recollection via the Precuneus/Posterior Cingulate Cortex–Medial Prefrontal Cortex Connectivity

Ying He, Hilary Sweatman, Alice R. Thomson, Zeus Garcia Tabuenca et autres

Self-related representation can enhance perception and memory—a phenomenon known as the self-referential effect (SRE). While SRE has been linked to the activation of the default mode network (DMN), including the precuneus/posterior cingulate cortex (Pcu/PCC) and the medial prefrontal cortex (mPFC), the underlying …

Specialization of anterior and posterior hippocampal functional connectivity differs in autism

Jonah Kember, Pascale Patenaude, Hilary Sweatman, Lachlan Van Schaik et autres

Structural and functional differences in the hippocampus have been related to the episodic memory and social impairments observed in autism spectrum disorder (ASD). In neurotypical individuals, hippocampal-cortical functional connectivity systematically varies between anterior and posterior hippocampus, with changes observed during typical development. …

Transforming Learning Data into a Machine Learning Model to Help STEM students Transition to University

Neeraj Katiyar, Armin Yazdani, Janette Barrington, Kira Smith et autres

Machine Learning (ML) may be a promising tool for predicting student success.Our research aims to predict student performance in specific STEM courses using ML.Self-reported scores on learning strategies, metacognitive awareness, mindset, and misconceptions about the brain were evaluated along with learning analytics …

A prognostic risk score for development and spread of chronic pain

Christophe Tanguay-Sabourin, Matt Fillingim, Gianluca V. Guglietti, Azin Zare et autres

Chronic pain is a complex condition influenced by a combination of biological, psychological and social factors. Using data from the UK Biobank (n = 493,211), we showed that pain spreads from proximal to distal sites and developed a biopsychosocial model that predicted …

Children's hypothetical reasoning about complex and dynamic systems

Angela Nyhout, Hilary Sweatman, Patricia A. Ganea

Children's hypothetical reasoning about a complex and dynamic causal system was investigated. Predominantly White, middle-class 5- to 7-year-old children from the Greater Toronto Area learned about novel food chains and were asked to consider the effects of removing one species on the …
