Visuomotor Rotation Adaptation And Workspace Manipulation: A Behavioral And Cognitive Emphasis, Reuben N. Addison
Visuomotor Rotation Adaptation And Workspace Manipulation: A Behavioral And Cognitive Emphasis, Reuben N. Addison
LSU Doctoral Dissertations
This is a three-study dissertation in which we aimed to broaden our knowledge of the mechanisms contributing to a 45° clockwise visuomotor adaptation by including variations in workspace. We provide behavioral and in one study physiological outcomes as evidence to support our conclusions. In the first experiment, we observed the adaptation of movement parameters such as pathlength, movement time, resultant velocity, and normalized jerk across groups trained with rotated visual feedback with both the left and right hands. Workspace location and hand differentially affected movement trajectory length. The group that practiced the task with their nondominant, left hand showed larger …
Turn That Frown Upside-Down! The Effectiveness Of Opposite Action In Changing Emotion, Kaitlyn Diane Chamberlain
Turn That Frown Upside-Down! The Effectiveness Of Opposite Action In Changing Emotion, Kaitlyn Diane Chamberlain
Graduate Theses and Dissertations
While research demonstrates that opposite action (OA) impacts emotion (Rizvi & Linehan, 2005), we lack an understanding of the mechanisms by which it produces opposite emotions. The current study dismantled emotion regulation skill components by comparing tasks with different combinations of cognitive, emotive and behavioral components. I predicted that the OA condition would be the most effective in altering negative emotion. University students (n = 194) completed a sadness induction and were randomly assigned to either a (1) control, (2) low arousal positive imagery (3) high arousal positive imagery, or (4) OA plus high arousal positive imagery condition. The control …
Neuroscience In Forensic Contexts: Ethical Concerns, Stephen J. Morse
Neuroscience In Forensic Contexts: Ethical Concerns, Stephen J. Morse
All Faculty Scholarship
This is a chapter in a volume, Ethics Challenges in Forensic Psychiatry and Psychology Practice, edited by Ezra E. H. Griffith, M.D. and to be published by Columbia University Press. The chapter addresses whether the use of new neuroscience techniques, especially non-invasive functional magnetic resonance imaging (fMRI) and the data from studies employing them raise new ethical issues for forensic psychiatrists and psychologists. The implicit thesis throughout is that if the legal questions, the limits of the new techniques and the relevance of neuroscience to law are properly understood, no new ethical issues are raised. A major ethical lapse …
Assessing The Synergistic Effect Of Caffeine And Sugar On Cognitive Performance In Undergraduate Students, Sandra P. Urquiza, Michelle Vieyra
Assessing The Synergistic Effect Of Caffeine And Sugar On Cognitive Performance In Undergraduate Students, Sandra P. Urquiza, Michelle Vieyra
Journal of the South Carolina Academy of Science
Working independently, both caffeine and sugar provide benefits to attention and memory. However, there is sparse literature on the synergistic effects on improved cognitive performance between caffeine and sugar when taken together. This study explored the dynamics between caffeine and sugar when consumed under ordinary conditions – as a cup of coffee. Twenty-four undergraduate students (15 women and 9 men) were asked to complete a baseline cognitive test, and one of the three variables was given at random in the form of a cup of coffee: decaffeinated with sugar, caffeinated with no sugar, and caffeinated with sugar. The remaining two …
Musical Expertise And Melodic Structure In Memory For Musical Notation, Andrea Halpern
Musical Expertise And Melodic Structure In Memory For Musical Notation, Andrea Halpern
Faculty Journal Articles
Two experiments plus a pilot investigated the role of melodic structure on short-term memory for musical notation by musicians and nonmusicians. In the pilot experiment, visually similar melodies that had been rated as either "good" or "bad" were presented briefly, followed by a 15-sec retention interval and then recall. Musicians remembered good melodies better than they remembered bad ones: nonmusicians did not distinguish between them. In the second experiment, good, bad, and random melodies were briefly presented, followed by immediate recall. The advantage of musicians over nonmusicians decreased as the melody type progressed from good to bad to random. In …
