Bradley Gibson, Ph.D.

Principal Investigator

The ability to act in a goal-directed fashion in spite of many competing forces is one of the hallmarks of adaptive human functioning. My research has examined how basic cognitive mechanisms such as selective attention and working memory optimize this adaptive behavior by allowing us to focus on, maintain, and retrieve goal-relevant information. One longstanding research interest concerns the extent to which the control of visual selective attention is voluntary (or goal-directed), and the extent to which salient objects and events in the world (e.g., unique colors, abrupt onset of stimuli or events, moving objects) can distract or “capture” our attention in an involuntary fashion, regardless of our current goals and intentions. Humans also use a wide variety of spatial symbols, ranging from abstract spatial words such as “above,” to iconic symbols such as arrows, to biologically-based symbols such as eye gaze, to control where others shift their attention. A major goal of my research is to provide a semantic-based theory of the symbolic control of spatial attention. A key feature of this theory is to explain how the processes underlying the comprehension of spatial symbols influence the distribution of attention in space. I have also developed a significant translational aspect to my study of goal-directed behavior that has involved working memory. Because working memory capacity may causally constrain the capacity to reason and learn, there has been great interest in knowing the extent to which working memory capacity is malleable, and, therefore, capable of being increased by adaptive training regimens as a strategy to improve reasoning and learning. I have recently created a novel training regimen that is capable of targeting the critical components of working memory capacity, and current research is investigating the extent to which this training can produce detectable improvements in reasoning and learning. Finally, I have also studied special populations of individuals who have both enhanced (synesthetes) and deficient (ADHD) working memory abilities to help understand how these abilities impact adaptive functioning.  

Jamie Trost Headshot

Jamie Trost, M.A.

Graduate Student, Lab Manager

Jamie Trost joined the AMP lab in the Fall of 2019. Jamie is a “double-Domer” who graduated from ND (class of 2015) with joint undergraduate degrees in Psychology and German. Prior to returning to Notre Dame, Jamie received a M.A. in Applied Behavioral Analysis and worked one-on-one with children and adults with ASD. Her research interests lie in understanding foundational and emerging models of attention and interoception. By better understanding these concepts and their associations to related diagnoses such as Autism Spectrum Disorder, Jamie hopes to contribute to research deficits and maladaptive processing related to attention, sensory-related deficits, and memory retrieval. She currently plans to pursue a professorship in academia that will allow her to combine her love of research and her passion for teaching.

David Lavender

Class of 2025

Hometown: Arlington Heights, IL

David Lavender first joined the AMP lab because of his interest in the mind, cognition, and neuroscience, specifically the corresponding mental illnesses and diseases that pertain to both. He was thoroughly interested in selective attention, mental processing, and the biological basis behind all three. With the skills and lessons learned through the AMP lab, he plans to apply to MD programs in the future.

Spencer Leatherberry Headshot

Spencer Leatherberry

Class of 2025

Hometown: Carmel, CA

Spencer joined the AMP lab because of her interest in psychology, specifically in regards to the inner workings of attention, introspection, and visual processing. She has always been fascinated with how the brain works and how certain psychological processes present themselves externally. Being in this lab gives her the opportunity to both explore her passion for psychology as well as give her scientific and research-based experience with the internal. Introspection, attention, and visual processing, play a paramount role in everyday life, and she is excited to delve deeper into understanding processes hidden from the naked eye.

Michael Lukowicz

Class of 2023

Hometown: Dallas, TX

Michael Lukowicz is a senior majoring in Neuroscience and Behavior in addition to Music. As a pre-med student, he is particularly interested in investigating attention, memory, and perception to ultimately advance clinical treatments. After thoroughly enjoying Dr. Gibson's Sensation & Perception class, Michael joined the AMP lab to further engage with these topics. Outside of school, Michael enjoys distance running, playing piano, and singing in the Glee Club. He plans to attend medical school next year after graduating from Notre Dame.

Syd Maxey

Class of 2025

Hometown: Detroit, MI

Sydney Maxey is currently a sophomore at ND. She decided to join the AMP lab because she am interested in how the brain interprets one’s environment and responds to certain stresses placed on the body, such as the COVID epidemic. She is interested in how perception influences human behavior. In addition, Syd would like to incorporate what she has learned about introspection in this lab to physician-patient interaction. Because Syd plans to attend medical school upon graduation, the knowledge she gains from this lab will help her connect with future patients. She believes understanding how the mind processes daily experiences will be beneficial to her as a physician one day.
