Prediction-Based Learning And Processing Of Event Knowledge., Ken Mcrae, Kevin S Brown, Jeffrey L Elman

Psychology Publications

Knowledge of common events is central to many aspects of cognition. Intuitively, it seems as though events are linear chains of the activities of which they are comprised. In line with this intuition, a number of theories of the temporal structure of event knowledge have posited mental representations (data structures) consisting of linear chains of activities. Competing theories focus on the hierarchical nature of event knowledge, with representations comprising ordered scenes, and chains of activities within those scenes. We present evidence that the temporal structure of events typically is not well-defined, but it is much richer and more variable both …

Following the trend of repurposing library space to meet modern user needs, Western University is undergoing a planned revitalization and renovation of its largest library on campus. As a result, 500,000 items will need to be shifted to other locations or off-site storage. In this session we will outline the impact of metadata work in shifting this large collection of material to a shared print preservation storage facility, in coordination with Western University’s Keep@Downsview partnership (https://downsviewkeep.org/). Keep@Downsview is a partnership of five universities to preserve the scholarly record in Ontario in a shared, high-density storage and preservation facility. We will …

A Framework For Considering Dissociative Identity Effects In Consumption, Bonnie Simpson, Lea Dunn, Katherine White

Management and Organizational Studies Publications

This chapter examines the mirror image of the identity association principle: dissociation. While the association principle posits that stimuli associated with a positively regarded identity receive more positive evaluations, the dissociation principle suggests that stimuli associated with negatively regarded identities will receive negative evaluations and be abandoned. The authors focus on the nature of dissociative reference groups or groups that the consumer is motivated to avoid association with, and present a framework outlining how dissociative influence can impact consumer behavior. They review the literature on dissociative influence and note that although dissociative reference groups often spur avoidance behaviors, they can …

A Macaque Connectome For Large-Scale Network Simulations In Thevirtualbrain, Kelly Shen, Gleb Bezgin, Michael Schirner, Petra Ritter, Stefan Everling, Anthony R. Mcintosh

Brain and Mind Institute Researchers' Publications

© 2019, The Author(s). Models of large-scale brain networks that are informed by the underlying anatomical connectivity contribute to our understanding of the mapping between the structure of the brain and its dynamical function. Connectome-based modelling is a promising approach to a more comprehensive understanding of brain function across spatial and temporal scales, but it must be constrained by multi-scale empirical data from animal models. Here we describe the construction of a macaque (Macaca mulatta and Macaca fascicularis) connectome for whole-cortex simulations in TheVirtualBrain, an open-source simulation platform. We take advantage of available axonal tract-tracing datasets and enhance the existing …

Predator-Induced Fear Causes Ptsd-Like Changes In The Brains And Behaviour Of Wild Animals, Liana Y. Zanette, Emma C. Hobbs, Lauren E. Witterick, Scott A. Macdougall-Shackleton, Michael Clinchy

Brain and Mind Institute Researchers' Publications

© 2019, The Author(s). Predator-induced fear is both, one of the most common stressors employed in animal model studies of post-traumatic stress disorder (PTSD), and a major focus of research in ecology. There has been a growing discourse between these disciplines but no direct empirical linkage. We endeavoured to provide this empirical linkage by conducting experiments drawing upon the strengths of both disciplines. Exposure to a natural cue of predator danger (predator vocalizations), had enduring effects of at least 7 days duration involving both, a heightened sensitivity to predator danger (indicative of an enduring memory of fear), and elevated neuronal …

Consciousness-Specific Dynamic Interactions Of Brain Integration And Functional Diversity, Andrea I. Luppi, Michael M. Craig, Ioannis Pappas, Paola Finoia, Guy B. Williams, Judith Allanson, John D. Pickard, Adrian M. Owen, Lorina Naci, David K. Menon, Emmanuel A. Stamatakis

Brain and Mind Institute Researchers' Publications

Prominent theories of consciousness emphasise different aspects of neurobiology, such as the integration and diversity of information processing within the brain. Here, we combine graph theory and dynamic functional connectivity to compare resting-state functional MRI data from awake volunteers, propofol-anaesthetised volunteers, and patients with disorders of consciousness, in order to identify consciousness-specific patterns of brain function. We demonstrate that cortical networks are especially affected by loss of consciousness during temporal states of high integration, exhibiting reduced functional diversity and compromised informational capacity, whereas thalamo-cortical functional disconnections emerge during states of higher segregation. Spatially, posterior regions of the brain’s default mode …

Altered Motor, Anxiety-Related And Attentional Task Performance At Baseline Associate With Multiple Gene Copies Of The Vesicular Acetylcholine Transporter And Related Protein Overexpression In Chat::Cre+ Rats, Craig P. Mantanona, Johan Alsiö, Joanna L. Elson, Beth M. Fisher, Jeffrey W. Dalley, Timothy Bussey, Ilse S. Pienaar

Brain and Mind Institute Researchers' Publications

© 2019, The Author(s). Transgenic rodents expressing Cre recombinase cell specifically are used for exploring mechanisms regulating behavior, including those mediated by cholinergic signaling. However, it was recently reported that transgenic mice overexpressing a bacterial artificial chromosome containing choline acetyltransferase (ChAT) gene, for synthesizing the neurotransmitter acetylcholine, present with multiple vesicular acetylcholine transporter (VAChT) gene copies, resulting in altered cholinergic tone and accompanying behavioral abnormalities. Since ChAT::Cre+ rats, used increasingly for understanding the biological basis of CNS disorders, utilize the mouse ChAT promotor to control Cre recombinase expression, we assessed for similar genotypical and phenotypical differences in such rats compared …

Are Specific Learning Disorders Truly Specific, And Are They Disorders?, Lien Peters, Daniel Ansari

Brain and Mind Institute Researchers' Publications

© 2019 The Authors Specific learning disorders, such as dyslexia and dyscalculia, are frequently studied to inform our understanding of cognitive development, genetic mechanisms and brain function. In this Opinion Paper, we discuss limitations of this research approach, including the use of arbitrary criteria to select groups of children, heterogeneity within groups and overlap between domains of learning. By drawing on evidence from cognitive science, neuroscience and genetics, we propose an alternative, dimensional framework. We argue that we need to overcome the problems associated with a categorical approach by taking into account interacting factors at multiple levels of analysis that …

Should It Stay Or Should It Go? Smartphone Dependency, Kira Foreman-Tran, Karina Schnurr, Ana C. Ruiz Pardo, John Paul Minda

Psychology Publications

As smartphones grow in use and popularity, it is important to understand the possible effects that varying levels of smartphone use may have on human cognition. Although smartphones provide many advantages for daily activities, one must also recognize the potential disadvantages. For example, smartphone use may lead to nomophobia, which is defined as the modern fear of not being able to access your smartphone or the internet (Yildirim & Correia, 2015). The present study used a pilot and main study to examine the effects smartphones have on human cognition. The pilot study was conducted to measure nomophobia, mobile phone involvement, …

Disability And Accessibility Language In Subject Headings And Social Tags, Mackenzie Johnson, Carlie Forsythe

FIMS Publications

Mackenzie Johnson and Carlie Forsythe’s article on disability and accessibility language in subject headings and social tagging stresses the importance of involving subject experts in the creation of subject headings, and of getting the headings right to allow effective information retrieval. The authors also assess the ‘third way’, of semi-structured, moderated social tagging systems, that lies between fully controlled vocabularies and free social tagging.

How Do You Solve A Problem Like The Whole User? The Construction Of Worthy And Problematic Users In Online Discussions Of The Public Library, Pam Mckenzie

FIMS Publications

In this article I use a discursive approach and the concept of the ‘category entitlement’ to analyse the ways that contributors to a public Internet discussion of the value of the public library make cases for different user characteristics and behaviour as ‘worthy’ or ‘problematic’, and use these characteristics to discuss and debate the kinds of individuals and the kinds of behaviour that properly belong to each category. Contributors to the discussion represented users in three categories: a fluid ‘everyone’, which included people represented as being disadvantaged and in legitimate need of the library’s resources, expertise, and support; the user …

Functional Localization Of The Frontal Eye Fields In The Common Marmoset Using Microstimulation, Janahan Selvanayagam, Kevin D. Johnston, David J. Schaeffer, Lauren K. Hayrynen, Stefan Everling

Brain and Mind Institute Researchers' Publications

Copyright © 2019 the authors. The frontal eye field (FEF) is a critical region for the deployment of overt and covert spatial attention. Although investigations in the macaque continue to provide insight into the neural underpinnings of the FEF, due to its location within a sulcus, the macaque FEF is virtually inaccessible to electrophysiological techniques such as high-density and laminar recordings. With a largely lissencephalic cortex, the common marmoset (Callithrix jacchus) is a promising alternative primate model for studying FEF microcircuitry. Putative homologies have been established with the macaque FEF on the basis of cytoarchitecture and connectivity; however, physiological investigation …

Preventing Adolescent Dating Violence: An Outcomes Protocol For Evaluating A Gender-Transformative Healthy Relationships Promotion Program, Deinera Exner-Cortens, Alysia Wright, Debb Hurlock, Roseline Carter, Pam Krause, Claire Crooks

Journal Articles

Adolescent dating violence (ADV) is a pressing public health problem in North America. Strategies to prevent perpetration are needed, and a substantial body of research demonstrates the importance of applying a gender lens to target root causes of adolescent dating violence as part of effective prevention. To date, however, there has been limited research on how to specifically engage boys in adolescent dating violence prevention. In this short communication, we describe the protocol for a longitudinal, quasi-experimental outcome evaluation of a program called WiseGuyz. WiseGuyz is a community-facilitated, gender-transformative healthy relationships program for mid-adolescent male-identified youth that aims to reduce …

Sign And Speech Share Partially Overlapping Conceptual Representations, Samuel Evans, Cathy J. Price, Jörn Diedrichsen, Eva Gutierrez-Sigut, Mairéad Macsweeney

Brain and Mind Institute Researchers' Publications

© 2019 The Author(s) Conceptual knowledge is fundamental to human cognition. Yet, the extent to which it is influenced by language is unclear. Studies of semantic processing show that similar neural patterns are evoked by the same concepts presented in different modalities (e.g., spoken words and pictures or text) [1–3]. This suggests that conceptual representations are “modality independent.” However, an alternative possibility is that the similarity reflects retrieval of common spoken language representations. Indeed, in hearing spoken language users, text and spoken language are co-dependent [4, 5], and pictures are encoded via visual and verbal routes [6]. A parallel approach …

Variational Representational Similarity Analysis, Karl J. Friston, Jörn Diedrichsen, Emma Holmes, Peter Zeidman

Brain and Mind Institute Researchers' Publications

© 2019 The Authors This technical note describes a variational or Bayesian implementation of representational similarity analysis (RSA) and pattern component modelling (PCM). It considers RSA and PCM as Bayesian model comparison procedures that assess the evidence for stimulus or condition-specific patterns of responses distributed over voxels or channels. On this view, one can use standard variational inference procedures to quantify the contributions of particular patterns to the data, by evaluating second-order parameters or hyperparameters. Crucially, this allows one to use parametric empirical Bayes (PEB) to infer which patterns are consistent among subjects. At the between-subject level, one can then …

Canada’S Feminist International Assistance Policy And Private Sector Engagement In Education: Considering Action For Girls’ And Women’S Education In Asia, Deanna Matthews, Prachi Srivastava

Education Publications

This brief aims to inform potential action in view of two significant developments in Canada’s international assistance strategy — the $400 million commitment to girls’ and women’s education in response to the Charlevoix Declaration on Quality Education for Girls, Adolescent Girls and Women in Developing Countries and the strategy for engaging in private sector partnerships in the Feminist International Assistance Policy. The brief is based on original analysis of data on activity by private foundations and private sector impact investors in girls’ and women’s education in East Asia and the Pacific and South Asia, drawing on a larger regional-level …

Cognitive Change In Cognitive-Behavioural Therapy, Leanne Quigley, David J A Dozois, R Michael Bagby, Daniela S S Lobo, Lakshmi Ravindran, Lena C Quilty

Psychology Publications

BACKGROUND: Although cognitive-behavioural therapy (CBT) is a well-established treatment for adult depression, its efficacy and efficiency may be enhanced by better understanding its mechanism(s) of action. According to the theoretical model of CBT, symptom improvement occurs via reductions in maladaptive cognition. However, previous research has not established clear evidence for this cognitive mediation model.

METHODS: The present study investigated the cognitive mediation model of CBT in the context of a randomized controlled trial of CBT v. antidepressant medication (ADM) for adult depression. Participants with major depressive disorder were randomized to receive 16 weeks of CBT (n = 54) or ADM …

A Sound-Sensitive Source Of Alpha Oscillations In Human Non-Primary Auditory Cortex, Alexander J. Billig, Björn Herrmann, Ariane E. Rhone, Phillip E. Gander, Kirill V. Nourski, Beau F. Snoad, Christopher K. Kovach, Hiroto Kawasaki, Matthew A. Howard, Ingrid S. Johnsrude

Brain and Mind Institute Researchers' Publications

Copyright © 2019 Billig, Herrmann et al. The functional organization of human auditory cortex can be probed by characterizing responses to various classes of sound at different anatomical locations. Along with histological studies this approach has revealed a primary field in posteromedial Heschl's gyrus (HG) with pronounced induced high-frequency (70-150 Hz) activity and short-latency responses that phase-lock to rapid transient sounds. Low-frequency neural oscillations are also relevant to stimulus processing and information flow, however, their distribution within auditory cortex has not been established. Alpha activity (7-14 Hz) in particular has been associated with processes that may differentially engage earlier versus …

An Accurate Registration Of The Bigbrain Dataset With The Mni Pd25 And Icbm152 Atlases., Yiming Xiao, Jonathan C Lau, Taylor Anderson, Jordan Dekraker, D Louis Collins, Terry Peters, Ali R Khan

Brain and Mind Institute Researchers' Publications

Brain atlases that encompass detailed anatomical or physiological features are instrumental in the research and surgical planning of various neurological conditions. Magnetic resonance imaging (MRI) has played important roles in neuro-image analysis while histological data remain crucial as a gold standard to guide and validate such analyses. With cellular-scale resolution, the BigBrain atlas offers 3D histology of a complete human brain, and is highly valuable to the research and clinical community. To bridge the insights at macro- and micro-levels, accurate mapping of BigBrain and established MRI brain atlases is necessary, but the existing registration is unsatisfactory. The described dataset includes …

Demystifying Wikipedia, Alie Visser, Erin Johnson

Western Libraries Presentations

Wikipedia: we all know it, and we all use it. As the 5th most visited website in the world, the English version of Wikipedia was viewed 92 billion times last year. Yet, in its short history, libraries have historically stigmatized this resource for its crowd-sourced editing system and inconsistent source quality. Increasingly, librarians from around the world are collaborating with Wikimedia to improve its authority by linking to open resources, hosting edit-a-thons, and integrating our organizational structures into Wikidata. In this workshop, we will highlight the power of the platform, the overlapping values of libraries and Wikipedia, and how both …

Interrogating Discourses Of Global Education: Reconceptualizing Education As A Common Good?, Prachi Srivastava

Education Publications

This contribution analyses UNESCO's framework of education as a common good in the context of the Global South. It argues that dominant conceptions view education in a narrow, instrumentalist perspective. Despite its promise to reorient education as a broader social endeavour towards human wellbeing to lead meaningful lives (Sen, 1999), UNESCO's framework has failed to gain significant traction. I argue this is linked to challenges associated with: education and unemployment; global mobility and learning assessment systems; citizenship education; and the global governance of education policymaking.

A Framework For Evaluating Correspondence Between Brain Images Using Anatomical Fiducials., Jonathan C Lau, Andrew G Parrent, John Demarco, Geetika Gupta, Jason Kai, Olivia W Stanley, Tristan Kuehn, Patrick J Park, Kayla Ferko, Ali R Khan, Terry M Peters

Brain and Mind Institute Researchers' Publications

Accurate spatial correspondence between template and subject images is a crucial step in neuroimaging studies and clinical applications like stereotactic neurosurgery. In the absence of a robust quantitative approach, we sought to propose and validate a set of point landmarks, anatomical fiducials (AFIDs), that could be quickly, accurately, and reliably placed on magnetic resonance images of the human brain. Using several publicly available brain templates and individual participant datasets, novice users could be trained to place a set of 32 AFIDs with millimetric accuracy. Furthermore, the utility of the AFIDs protocol is demonstrated for evaluating subject-to-template and template-to-template registration. Specifically, …

Terrorism And Its Legal Aftermath: The Limits On Freedom Of Expression In Canada’S Anti-Terrorism Act & National Security Act, Percy Sherwood

FIMS Publications

This analysis aims to demonstrate how s. 83.221 in Bill C-51 is likely to violate freedom of expression guaranteed under the Charter. The first section employs the two-step Irwin Toy analysis to show that the speech offense infringes upon s. 2(b) of the Charter. The second section uses the Oakes test to determine whether the breach of freedom of expression is a reasonable limit. On whether the speech offense can be justified under s. 1 of the Charter as a reasonable limit, the legislation fails at the third and fourth step of the Oakes test. Section three of this paper …

"Being In Time": New Public Management, Academic Librarians, And The Temporal Labor Of Pink-Collar Public Service Work, Karen P. Nicholson

FIMS Publications

Time is a site of power, one that enacts particular subjectivities and relationships. In the workplace, time enables and constrains performance, attitudes, and behaviors. In this qualitative research study, I examine the impact of the values and practices of new public management on academic librarians’ experiences of time when engaged in pink-collar public service (reference and information literacy) work. Data gathered during semi-structured interviews with twenty-four public service librarians in Canadian public research-intensive universities, members of the U15 Group, serve as a site of analysis for this study. Interview data were first analyzed using thematic analysis (Braun and Clarke 2006) …

Stress And Well-Being At The Consumer-Employee Interface, Bonnie Simpson, Madelynn Stackhouse, Katherine White

Management and Organizational Studies Publications

Although stress has become a prominent research theme in consumer behavior and occupational health, to the authors knowledge there is only one review on the relationship between consumer behavior and stress (i.e., when internal and external factors exceed an individual’s resources and endangering the individual’s well-being) and this was published 10 years ago. Further, research on occupational stress has yet to be fully integrated into the consumer stress literature. In this chapter, the authors attempt to advance research on consumer stress by a drawing on a satisfaction mirror framework which outlines that consumers and employees influence each other through a …

Thirty-Five Years Of Computerized Cognitive Assessment Of Aging — Where Are We Now?, Avital Sternin, Alistair Burns, Adrian M. Owen

Brain and Mind Institute Researchers' Publications

Over the past 35 years, the proliferation of technology and the advent of the internet have resulted in many reliable and easy to administer batteries for assessing cognitive function. These approaches have great potential for affecting how the health care system monitors and screens for cognitive changes in the aging population. Here, we review these new technologies with a specific emphasis on what they offer over and above traditional ‘paper-and-pencil’ approaches to assessing cognitive function. Key advantages include fully automated administration and scoring, the interpretation of individual scores within the context of thousands of normative data points, the inclusion of …

Stimulus-Locked Responses On Human Upper Limb Muscles And Corrective Reaches Are Preferentially Evoked By Low Spatial Frequencies, Rebecca A. Kozak, Philipp Kreyenmeier, Chao Gu, Kevin Johnston, Brian D. Corneil

Brain and Mind Institute Researchers' Publications

© 2019 Kozak et al. In situations requiring immediate action, humans can generate visually-guided responses at remarkably short latencies. Here, to better understand the visual attributes that best evoke such rapid responses, we recorded upper limb muscle activity while participants performed visually-guided reaches towards Gabor patches composed of differing spatial frequencies (SFs). We studied reaches initiated from a stable posture (experiment 1, a static condition), or during on-line reach corrections to an abruptly displaced target (experiment 2, a dynamic condition). In both experiments, we detail the latency and prevalence of stimulus-locked responses (SLRs), which are brief bursts of EMG activity …
