Article
Abstract Background Neurological disorders and mental health conditions, including mood/anxiety disorders, are a leading cause of disability and healthcare use. These disorders have shared risk factors and commonly co-occur in older adults. Mood/anxiety disorders are often under-diagnosed and under-treated among those with neurological disorders, p...
Article
Little has been quantified, at a population‐level, about the magnitude of heath service disruption to persons living with dementia in community settings during the COVID‐19 pandemic. Sustained access to health care services is particularly important for persons with dementia and other neurodegenerative diseases as they are vulnerable to decline. He...
Article
Background: Free-text fields in electronic medical records (EMRs) are a rich source of information about persons with dementia. The signs and symptoms of dementia (e.g., responsive behaviours, cognitive impairment) can present to primary care providers many years before a formal diagnosis. We used natural language processing (NLP) to develop a lis...

Money laundering is a pervasive legal and economic problem that hides criminal activity. Identifying money laundering is a priority for both banks and governments, thus, machine learning algorithms have emerged as a possible strategy to detect suspicious financial activity within financial institutions. We used traditional regression and supervised...
Article
Sound-shape crossmodal correspondence, the naturally occurring associations between abstract visual shapes and nonsense sounds, is one aspect of multisensory processing that strengthens across early childhood. Little is known regarding whether school-aged children exhibit other variants of sound-shape correspondences such as audio-tactile (AT) asso...

STUDY OBJECTIVE: To characterize oral health practices using data from statewide, multi-stakeholder surveys. STUDY DESIGN AND METHODS: We analyzed data from two Rhode Island surveys. Together, the surveys targeted all nursing homes, residents, and resident representatives in Rhode Island, and asked about staff training on mouth care, frequency of...
Article
Background: In nursing homes, residents with dementia frequently receive potentially inappropriate medications that are associated with an increased risk of adverse events. Despite known sex differences in clinical presentation and sociodemographic characteristics among persons with dementia, few studies have examined sex differences in patterns a...
Article
Full-text available
Background: Population-based assessments of the association between personal technology use and cognitive performance have shown positive effects among seniors. However, prior cognitive function, which predicts future technology use, is seldom considered as a potential confounder in previous cross-sectional studies. Objective: Estimate the associat...

There is a well-established relationship between high ambient temperature and risk of death. However, the number of deaths attributable to heat each year in the United States remains incompletely quantified. Methods: We replicated the approach from a large, international study to estimate temperature-mortality associations in 297 United States co...
Article
Introduction Antipsychotics are widely used to treat neuropsychiatric symptoms (NPS) of dementia in long-term care (LTC), despite many adverse effects. Targeted quality improvement, broader awareness of risks, and other initiatives over the last ten years have resulted in substantial reductions in antipsychotic prescribing in Canadian LTC, but conc...
Article
Importance Physician attitudes about websites that publicly report health care quality and experience data have not been recently described. Objectives To examine physician attitudes about the accuracy of websites that report information about quality of care and patient experience and to describe physician beliefs about the helpfulness of these d...
Article
Full-text available
One source of information we glean from everyday experience, which guides social interaction, is assessing the emotional state of others. Emotional state can be expressed through several modalities: body posture or movements, body odor, touch, facial expression, or the intonation in a voice. Much research has examined emotional processing within on...
Article
Advance care planning (ACP) conversations occur infrequently among patients and their health care professionals, and when they do occur, the context is often a stressful clinical situation.¹,2 Advance care planning conversations that occur too late (or not at all) can result in care that is invasive, expensive, and not aligned with patients’ wishes...
Article
The Centers for Medicare & Medicaid Services (CMS) reported 15,634 certified nursing homes in the United States in 2014. Approximately 1.4 million older adults reside in nursing homes due to a variety of clinical and social factors. Older adults who transition into nursing home care tend to have a greater prevalence of cognitive and physical morbid...

Faces drive our social interactions. A vast literature suggests an interaction between gender and emotional face perception, with studies using different methodologies demonstrating that the gender of a face can affect how emotions are processed. However, how different is our perception of affective male and female faces? Furthermore, how does our...
Poster
Faces convey a wealth of information, cueing us to features such as the gender, identity or emotional status of individuals, and providing crucial signals for navigating social interactions. We examined the extent to which emotionally charged voices alter the emotion seen in a face and the corresponding physiological stress response. We used face a...
Poster
Crossmodal correspondence, the association of information across the senses, is an ubiquitous multisensory phenomenon. The bouba/kiki effect, a prime example, finds an association between an abstract shape, spikey or round, and a nonsense word, /kiki/ or /baba/, respectively. This effect is found across cultures and languages, early in development,...
Presentation
Full-text available
There is long standing interest in understanding how features of a face are represented, with behavioral and neuronal data suggesting independent as well as interdependent processing (for example, (Bestelmeyer, Jones, DeBruine, Little, & Welling, 2010; Haxby, Hoffman, Gobbini, 2000; Ng, Ciaramitaro, Anstis, Boynton, Fine, 2006). We used contingent...
Article
Full-text available
While some models of how various attributes of a face are processed have posited that face features, invariant physical cues such as gender or ethnicity as well as variant social cues such as emotion, may be processed independently (e.g., Bruce & Young, 1986), other models suggest a more distributed representation and interdependent processing (e.g...
