Short-Duration Stimulation Of The Supplementary Eye Fields Perturbs Anti-Saccade Performance While Potentiating Contralateral Head Orienting., Brendan B Chapman, Brian D Corneil

Brain and Mind Institute Researchers' Publications

Many forms of brain stimulation utilize the notion of state dependency, whereby greater influences are observed when a given area is more engaged at the time of stimulation. Here, by delivering intracortical microstimulation (ICMS) to the supplementary eye fields (SEF) of monkeys performing interleaved pro- and anti-saccades, we show a surprising diversity of state-dependent effects of ICMS-SEF. Short-duration ICMS-SEF passed around cue presentation selectively disrupted anti-saccades by increasing reaction times and error rates bilaterally, and also recruited neck muscles, favoring contralateral head turning to a greater degree on anti-saccade trials. These results are consistent with the functional relevance of the …

An Invitation To The Study Of Brain Networks, With Some Statistical Analysis Of Thresholding Techniques, Mark Daley

Brain and Mind Institute Researchers' Publications

We provide a brief introduction to the nascent application of network theory to mesoscale networks in the human brain. Following an overview of the typical data-gathering, processing, and analysis methods employed in this field, we describe the process for inferring a graph from neural time series. A crucial step in the construction of a graph from time series is the thresholding of graph edges to ensure that the graphs represent physiological relationships rather than artifactual noise. We discuss the most popular currently employed methodologies and then introduce one of our own, based on the theory of random matrices. Finally, we …

Observing Object Lifting Errors Modulates Cortico-Spinal Excitability And Improves Object Lifting Performance., Gavin Buckingham, Jeremy D Wong, Minnie Tang, Paul L Gribble, Melvyn A Goodale

Brain and Mind Institute Researchers' Publications

Observing the actions of others has been shown to modulate cortico-spinal excitability and affect behaviour. However, the sensorimotor consequences of observing errors are not well understood. Here, participants watched actors lift identically weighted large and small cubes which typically elicit expectation-based fingertip force errors. One group of participants observed the standard overestimation and underestimation-style errors that characterise early lifts with these cubes (Error video--EV). Another group watched the same actors performing the well-adapted error-free lifts that characterise later, well-practiced lifts with these cubes (No error video--NEV). We then examined actual object lifting performance in the subjects who watched the EV …

Sign Language Ability In Young Deaf Signers Predicts Comprehension Of Written Sentences In English., Kathy N Andrew, Jennifer Hoshooley, Marc F Joanisse

Brain and Mind Institute Researchers' Publications

We investigated the robust correlation between American Sign Language (ASL) and English reading ability in 51 young deaf signers ages 7;3 to 19;0. Signers were divided into 'skilled' and 'less-skilled' signer groups based on their performance on three measures of ASL. We next assessed reading comprehension of four English sentence structures (actives, passives, pronouns, reflexive pronouns) using a sentence-to-picture-matching task. Of interest was the extent to which ASL proficiency provided a foundation for lexical and syntactic processes of English. Skilled signers outperformed less-skilled signers overall. Error analyses further indicated greater single-word recognition difficulties in less-skilled signers marked by a higher …

Links Between White Matter Microstructure And Cortisol Reactivity To Stress In Early Childhood: Evidence For Moderation By Parenting., Haroon I Sheikh, Marc F Joanisse, Sarah M Mackrell, Katie R Kryski, Heather J Smith, Shiva M Singh, Elizabeth P Hayden

Brain and Mind Institute Researchers' Publications

Activity of the hypothalamic-pituitary-adrenal axis (measured via cortisol reactivity) may be a biological marker of risk for depression and anxiety, possibly even early in development. However, the structural neural correlates of early cortisol reactivity are not well known, although these would potentially inform broader models of mechanisms of risk, especially if the early environment further shapes these relationships. Therefore, we examined links between white matter architecture and young girls' cortisol reactivity and whether early caregiving moderated these links. We recruited 45 6-year-old girls based on whether they had previously shown high or low cortisol reactivity to a stress task at …

Sensitivity Of Human Auditory Cortex To Rapid Frequency Modulation Revealed By Multivariate Representational Similarity Analysis., Marc F Joanisse, Diedre D Desouza

Brain and Mind Institute Researchers' Publications

Functional Magnetic Resonance Imaging (fMRI) was used to investigate the extent, magnitude, and pattern of brain activity in response to rapid frequency-modulated sounds. We examined this by manipulating the direction (rise vs. fall) and the rate (fast vs. slow) of the apparent pitch of iterated rippled noise (IRN) bursts. Acoustic parameters were selected to capture features used in phoneme contrasts, however the stimuli themselves were not perceived as speech per se. Participants were scanned as they passively listened to sounds in an event-related paradigm. Univariate analyses revealed a greater level and extent of activation in bilateral auditory cortex in response …

Dopaminergic Medication Impairs Feedback-Based Stimulus-Response Learning But Not Response Selection In Parkinson's Disease., Andrew Vo, Nole M Hiebert, Ken N Seergobin, Stephanie Solcz, Allison Partridge, Penny A Macdonald

Brain and Mind Institute Researchers' Publications

Cognitive dysfunction is a feature of Parkinson's Disease (PD). Some cognitive functions are impaired by dopaminergic medications prescribed to address the movement symptoms that typify PD. Learning appears to be the cognitive function most frequently worsened by dopaminergic therapy. However, this result could reflect either impairments in learning (i.e., acquisition of associations among stimuli, responses, and outcomes) or deficits in performance based on learning (e.g., selecting responses). We sought to clarify the specific effects of dopaminergic medication on (a) stimulus-response association learning from outcome feedback and (b) response selection based on learning, in PD. We tested 28 PD patients on …

Rule-Based Category Learning In Children: The Role Of Age And Executive Functioning., Rahel Rabi, John Paul Minda

Brain and Mind Institute Researchers' Publications

Rule-based category learning was examined in 4-11 year-olds and adults. Participants were asked to learn a set of novel perceptual categories in a classification learning task. Categorization performance improved with age, with younger children showing the strongest rule-based deficit relative to older children and adults. Model-based analyses provided insight regarding the type of strategy being used to solve the categorization task, demonstrating that the use of the task appropriate strategy increased with age. When children and adults who identified the correct categorization rule were compared, the performance deficit was no longer evident. Executive functions were also measured. While both working …

The Motivating Role Of Dissociative Outgroups In Encouraging Positive Consumer Behaviors, Katherine White, Bonnie Simpson, Jennifer Argo

Management and Organizational Studies Publications

Previous research has found that people tend to avoid products or behaviors that are linked to dissociative reference groups. The present research demonstrates conditions under which consumers exhibit similar behaviors to dissociative out-group members in the domain of positive consumption behaviors. In particular, when a consumer learns that a dissociative out-group performs comparatively well on a positive behavior, the consumer is more likely to respond with positive intentions and actions when the setting is public (vs. private). The authors suggest that this occurs because learning of the successful performance of a dissociative out-group under public conditions threatens the consumer’s group …

Is The Very Notion Of “Representation” Relevant For The Regulation Game Of Video Game Developers?, Marie-Josee Legault, Johanna Weststar

Management and Organizational Studies Publications

Using Kelly’s mobilisation theory (1998) to assess their propensity to collective action, this article examines where videogame developers stand regarding the representation of their interests. These workers are good examples of knowledge work in project-based organisations. If Kelly’s model allows in general for projections of unionisation in a given sector, we find this is not the case here. Rather, our study leads us to observe how much the labour market has changed since the elaboration of Kelly’s model, and how much these workers’ needs differ from the options laid out by traditional unions’ action as presented by Kelly. This group …

The Logogenesis Of Writing To Learn: A Systemic Functional Perspective., Perry Klein, Len Unsworth

Education Publications

Writing to learn has become an important practice in science education. How is scientific knowledge constructed during writing? To investigate this question, we examined the process through which four university students constructed written explanations of either projectile motion or buoyancy. The analysis, informed by systemic functional linguistics, focused on the mapping of semantic elements to grammatical choices, and the way in which this mapping unfolded throughout the course of each text. The texts began largely congruently; grammar mapped closely to experience. Gradually, each text shifted toward greater use of grammatical metaphor. Nominalization allowed propositions and sequences of events to serve …

Training Lawyers, Cultivating Citizens, And Re-Enchanting The Legal Professional, David Sandomierski

Law Publications

Law schools ought to have a vision for how they contribute to the public good. This article identifies two views of how public value might fit into the mission of the law school. The additive view holds that pursuing public value (cultivating “citizens”) and training “lawyers” are distinct objectives. This view underlies traditional claims that the law school should be housed in the university, and also accounts for the historic tension between academic law schools and the profession.

By contrast, the integrative view holds that training lawyers and cultivating citizens are mutually reinforcing. This view inheres in the desire to …

Failure To Replicate Retrocausal Recall, Imants Barušs, Vanille Rabier

Psychology

In two temporally inverted memory experiments, Daryl Bem found that participants had better recall for words that were practiced after the recall task than for control words that were not practiced after the recall task. We attempted to replicate the second of Bem’s two experiments with the addition of a personality measure. After completing the Six Factor Personality Questionnaire, participants (n = 102) interacted with a computer on which they were shown 48 nouns, one at a time, then asked to type as many of the words as they could recall, and then asked to practice a random selection …

Questions About Interacting With Invisible Intelligences, Imants Barušs

Psychology

So little of the physical universe is made up of the sort of material of which we think reality is made. Indeed 96% of it consists of dark matter and dark energy. And of the 4% made of “matter” as we ordinarily understand it, only a tiny sliver reflects visible light. Yet our ideas about what can or cannot be “out there” are often based on our minuscule exposure to the visible part of the universe. And we assume that whatever might be “out there,” where we cannot see anything, surely must be insentient. But what if we are wrong? …

Emotional Processing In Music: Study In Affective Responses To Tonal Modulation In Controlled Harmonic Progressions And Real Music, Marina Korsakova-Kreyn, Jay W. Dowling

Lander College for Women - The Anna Ruth and Mark Hasten School Publications and Research

Tonal modulation is one of the main structural and expressive aspects of music in the European musical tradition. Experiment 1 investigated affective responses to modulations to all eleven major and minor keys (relative to the starting tonality) in brief, specially constructed harmonic progressions, by using six bipolar scales related to valence, potency, and synaesthesia. The results indicated the dependence of affective response on degree of modulation in terms of key proximity, and of mode. Experiment 2 examined affective responses to the most common modulations in nineteenth-century piano music: to the subdominant, dominant, and minor sixth in the major mode. The …

Revisiting Pragmatic Abilities In Autism Spectrum Disorder, Jessica De Villiers, Brooke Myers, Robert Stainton

Philosophy Publications

In a 2007 paper, we argued that speakers with Autism Spectrum Disorders (ASDs) exhibit pragmatic abilities which are surprising given the usual understanding of communication in that group. That is, it is commonly reported that people diagnosed with an ASD have trouble with metaphor, irony, conversational implicature and other non-literal language. This is not a matter of trouble with knowledge and application of rules of grammar. The difficulties lie, rather, in successful communicative interaction. Though we did find pragmatic errors within literal talk, the transcribed conversations we studied showed many, many successes. A second paper reinforced our finding of a …

The Progressive Movement And Conservation (1890s - Present), John Freemuth

Political Science Faculty Publications and Presentations

The Progressive movement of the 1890s to the 1920s was a seminal movement affecting the U.S. policy in many areas. Specifically, the original conservation movement, part of the larger Progressive movement during this same time period (1890-1920), had a profound influence over natural resource policies that remain to this day. Perhaps best seen as a response to the changes brought by the modernization of life in the United States, key aspects of the Progressive movement were electorial reform to counter political corruption, the women's movement, fear of corporate power, and the need to control that power.

The Relationship Between Emotional Intelligence And Leadership Styles Of African American Law Enforcement Executives, B. Bernard Ferguson

2010-2016 Archived Posters

Ineffective leadership within police organizations has resulted in worker disengagement, absenteeism, and high turnover. This quantitative study examined the relationship between ethnicity, emotional intelligence (EI) and leadership styles of African American law enforcement executives. Hypotheses were tested using data collected from 130 members of the National Organization of Black Law Enforcement Executives (NOBLE), and comparing results to data from a prior similar study using Caucasian law enforcement executives. Results indicated that ethnicity had a statistically significant relationship with EI and leadership style factors.

Examining The Effect Of Medical-Surgical Nurse Manager Leadership On Employee Organizational Citizenship, Cheryl B. Cullen

2010-2016 Archived Posters

An intriguing question in a hospital is “What makes one medical-surgical nursing unit more desirable to nurses, physicians, and patients than another?” This quantitative, correlational research study identified a moderately positive correlation (r = .35, p = .000 between the leadership and communication behaviors of the nurse manager and the organizational citizenship of the nurses and nursing assistants who worked on the medical-surgical nursing units studied. The social impact of this positive correlation is better patient care outcomes.
