rTMS reduces cortical imbalance associated with visual hallucinations after occipital stroke
(2016-10)Objective: To investigate the efficacy of multiday repetitive transcranial magnetic stimulation (rTMS) to the occipital cortex in a patient with continuous visual phosphene hallucinations for more than 2 years following ... -
Own-age and own-sex biases in recognition of aged faces
(2013-10)It is surprising how easily we are able to recognize people whom we have not seen in many years, somehow compensating for the aging-related facial changes that occurred. We measured the limits of the ability to recognize ... -
Own-age and own-sex biases in recognition of aged faces.
(2013-10)It is surprising how easily we are able to recognize people whom we have not seen in many years, somehow compensating for the aging-related facial changes that occurred. We measured the limits of the ability to recognize ... -
Evidence of multisensory plasticity: Asymmetrical medial geniculate body in people with one eye
(NeuroImage: Clinical, 2015-10)The medial geniculate body (MGB) plays a central role in auditory processing with both efferent and afferent tracts to primary auditory cortex. People who have lost one eye early in life have enhanced sound localization, ... -
Consecutive TMS-fMRI reveals an inverse relationship in BOLD signal.
(Journal of Neuroscience, 2013-12)The human visual system is capable of recognizing an infinite number of scenes containing an abundance of rich visual information. There are several cortical regions associated with the representation of a scene, including ... -
TMS to lateral occipital cortex disrupts object processing but facilitates scene processing.
(Journal of Cognitive Neuroscience, 2011-11)The study of brain-damaged patients and advancements in neuroimaging have lead to the discovery of discrete brain regions that process visual image categories, such as objects and scenes. However, how these visual image ... -
Behavioural and neuroimaging evidence for a contribution of color and texture information to scene classification in a patient with visual form agnosia.
(Journal of Cognitive Neuroscience, 2004-03)A common notion is that object perception is a necessary precursor to scene perception. Behavioral evidence suggests, however, that scene perception can operate independently of object perception. Further, neuroimaging has ... -
Altered white matter connectivity associated with visual hallucinations following occipital stroke
(Brain and Behavior, 2018-05)Introduction Visual hallucinations that arise following vision loss stem from aberrant functional activity in visual cortices and an imbalance of activity across associated cortical and subcortical networks subsequent ... -
TMS to the TOS impairs scene but not object categorization
(Journal of Cognitive Neuroscience, 2013-06)Traditionally, it has been theorized that the human visual system identifies and classifies scenes in an object-centered approach, such that scene recognition can only occur once key objects within a scene are identified. ... -
Altered anterior visual system development following early monocular enucleation
(NeuroImage: Clinical, 2014)Purpose Retinoblastoma is a rare eye cancer that generally occurs before 5 years of age and often results in enucleation (surgical removal) of the cancerous eye. In the present study, we sought to determine the consequences ... -
Altered brain morphology following long-term survival from early monocular enucleation.
(NeuroImage: Clinical, 2015)Purpose Retinoblastoma is typically diagnosed before 5 years of age and is often treated by enucleation (surgical removal) of the cancerous eye. Here, we sought to characterize morphological changes of the cortex following ... -
Victimization and Perpetration Experiences of Adults with Autism
(Frontiers Media, 25/05/2018)This study aimed to describe the self-reported experiences of childhood and adult victimization and perpetration in adults with autism spectrum conditions (ASC) compared to a matched sample, and how victimization and ... -
Infant Clinical Pain Assessment: Core Behavioural Cues
(The Journal of Pain, 2018)Diverse behavioral cues have been proposed to be useful cues in infant pain assessment, but there is a paucity of evidence on the basis of formal psychometric evaluation to establish their validity for this purpose. We ... -
Developing a Measure of Distress-Promoting Parent Behaviours During Infant Vaccination: Assessing Reliability and Validity
(Canadian Journal of Pain, 2018)Background: Infants rely on their parents’ sensitive and contingent soothing to support their regulation from pain-related distress. However, despite being of potentially equal or greater import, there has been little focus ... -
Comparing means under heteroscedasticity and nonnormality: Further exploring robust means modeling
(Wayne State University Library System, 2018)Researchers are commonly interested in comparing the means of independent groups when distributions are nonnormal and variances are unequal. Robust means modeling (RMM) has been proposed as an alternative to ANOVA-type ... -
Testing for a Lack of Relationship Among Categorical Variables
(Open Access Scholarly Publishers Association, 2018)Determining a lack of association among two or more categorical variables is frequently necessary in psychological designs such as comparative outcome analyses, assessments of group equivalence at a baseline level, and ... -
Light and heavy heterosexual activities of young Canadian adolescents: Normative patterns and differential predictors
(Wiley, 2008)The objectives of this research were to explore patterns of heterosexual activity in early adolescence and to examine the differential pathways to light and heavy heterosexuality. We utilized the National Longitudinal ... -
Tests for Treatment Group Equality When Data are Nonnormal and Heteroscedastic
(Wayne State University Library System, 2007)Several tests for group mean equality have been suggested for analyzing nonnormal and heteroscedastic data. A Monte Carlo study compared the Welch tests on ranked data and heterogeneous, nonparametric statistics with ... -
Psychological correlates of fatigue: Examining depression, perfectionism, and automatic negative thoughts
(Elsevier, 2007)This study investigated whether depression, perfectionism or automatic negative thoughts would correlate with the symptomatology of fatigue in a non-clinical population. A structural model was developed to determine if ... -
The effects of heteroscedasticity on tests of equivalence
(Wayne State University Library System, 2007)Tests of equivalence, which are designed to assess the similarity of group means, are becoming more popular, yet very little is known about the statistical properties of these tests. Monte Carlo methods are used to compare ...
