Abstract: <p>Ageism is pervasive and harmful, creating an urgent need to understand how ageist attitudes can be improved. Building on the novel age-conscious student concept, this thesis explored the outcomes of a pilot intergenerational classroom, aimed at reducing ageism, that integrated 13 older community participants into a university-based psychology of aging course alongside 60 younger students… more

Abstract: <p>Maladaptive fear can develop when nonthreatening stimuli are misinterpreted as dangerous. While fear extinction has been extensively studied, organisms can also learn safety through relief learning, in which cues signalling the termination of an aversive event acquire positive value. Although the medial prefrontal cortex (mPFC) is implicated in regulating responses to threat and safety… more

This study tests the hypothesis that: 1) freezing is linked to
executive dysfunction; 2) freezing is a global motor phenomenon, not limited to gait. We
compared 14 PwPD to 16 controls. Several aspects of executive function were measured
using pro- and anti-saccade tasks… more

Abstract: <p>Freezing of gait is a debilitating symptom affecting individuals with Parkinson's disease. Emerging evidence suggests freezing may represent a global motor control deficit beyond gait. We investigated freezing episodes in the upper limbs using spatially-constrained reaching tasks known to elicit freezing of gait. Fourteen people with Parkinson's disease and 13 controls… more

Abstract: <p>Stress during adolescence has profound effects on psychological, behavioral, and neurobiological outcomes in adulthood. This study investigates the impact of adolescent stress on safety learning, anxiety- and depressive-like behaviors, and associated neurocircuitry using a rat model. Adolescent male Long Evans rats underwent an unpredictable intermittent stress regimen, followed by… more
