Background: Some individuals who sustain traumatic brain injuries (TBIs) continue to experience significant cognitive impairments chronically (months to years post injury). Many tests of executive function are insensitive to these executive function impairments, as such impairments may only appear during complex daily life conditions. Daily life o...

Traumatic brain injuries (TBIs) occur when we receive a harmful blow to the head that results in disruptions to normal brain functioning. TBIs often cause cognitive deficits that include difficulties in concentration (e.g., mental fog), planning, and setting/achieving goals. These cognitive abilities are often classified more broadly as executive f...

Analogical reasoning—our ability to abstract relational similarities between situations despite surface-level differences—varies between individuals; however, current analogy tasks are often not difficult enough to capture variability in performance across healthy and clinical populations. To address this challenge, we developed a scene analogy ass...

Performing relational comparisons is considered among the most intelligent cognitive capacities. Animal studies have demonstrated that chimpanzees and crows are capable of relational reasoning with second-order relationships (e.g., analogies); however, it has been hypothesized that only humans are capable of reasoning with third-order relationships...

Article
Full-text available
Depression is the most frequent comorbid psychiatric condition among individuals with traumatic brain injury (TBI). Yet, little is known about changes in the brain associated with reduced depressive symptoms following rehabilitation for TBI. We identified whether cognitive training alleviates comorbid depressive symptoms in chronic TBI (>6 months p...
Article
Full-text available
Clinical investigations of individuals with chronic stage traumatic brain injury (TBI) showing mild-to-moderate levels of residual impairment largely use standardized neuropsychological assessments to measure executive functioning. The Hayling Sentence Completion Test (HSCT) relies upon several executive functions but detects cognitive impairments...

Poster to be presented at the annual American Congress of Rehabilitation Medicine (ACRM) in Chicago, IL. Presents a partial least squares correlation analysis of the relationships between BOLD response and white matter microstructure in adults with chronic mild-moderate traumatic brain injury (TBI). Note: the currently published abstract in the Arc...

Analogical reasoning—the ability to understand and utilize relational similarities between entities despite surface-level differences—helps individuals solve problems and navigate through novel situations. This ability varies across healthy and clinical populations, yet current analogical reasoning tasks often fail to capture subtle performance var...

Top-down strategic cognitive intervention results in changes in white matter axial diffusivity in a priori selected ROIs and improvements in assessments of executive functioning.

Traumatic brain injury (TBI) is a chronic health condition. The prevalence of TBI, combined with limited advances in protocols to mitigate persistent TBI-related impairments in higher order cognition, present a significant challenge. In this randomised study (n = 60), we compared the benefits of Strategic Memory Advanced Reasoning Training (SMART,...
Article
Despite evidence that individuals with bipolar disorder have neurocognitive impairment that persists during euthymia, the impact of changes in affective symptoms on cognitive function has not been well established. Here, we sought to determine whether specific neurocognitive functions are sensitive to mood changes in individuals with bipolar disord...
Article
Cognitive processing inefficiency, often measured using digit symbol coding tasks, is a putative vulnerability marker for schizophrenia and a reliable indicator of illness severity and functional outcome. Indeed, performance on the digit symbol coding task may be the most severe neuropsychological deficit patients with schizophrenia display at the...

Goals: 1) explore executive dysfunction in chronic-phase traumatic brain injury (TBI) using the Hayling Sentence Completion Test (Burgess & Shallice, 1996, 1997) and 2) improve how errors are scored by applying Latent Semantic Analysis (LSA; Landauer, Foltz, & Laham, 1998) and lexical estimates (e.g., word frequency) to characterize the quality of word generations.
