Biography

The study of the relationship between psychology and biology goes by many names, including: Biopsychology, Psychobiology, Biological Psychology, and Behavioral Neuroscience. No matter what name you choose to use, it is the discipline that delves into the interaction of the mind and the body and seeks to understand how our biology contributes to our thoughts and behavior. Neuroscientists and behavioral psychologists use a variety of experimental models, including individual neurons, live animals, and even humans, with methods involving electrophysiology, genetics, pharmacology, and biochemistry, among many others. Dr. Keith Feigenson’s path to Albright College has taken him through many of these disciplines, as he has tried to approach the the human mind from a variety of different angles. Dr. Feigenson’s graduate background was in developmental neuroscience, investigating the changes of neurons in models of multiple sclerosis. Since then, he been studying some of the perceptual and cognitive problems facing people with serious mental illnesses, such as schizophrenia. Dr. Feigenson’s current research involves exploring how we can understand neurobiological processes by studying human behavior.

Areas of Research

Perceptual organization and optical illusions

Perceptual organization is how we interpret our surroundings by combining individual pieces of stimuli into coherent wholes. It depends on the ability to interpret context, such as estimating an object’s size by comparing it to other nearby objects and is often impaired in schizophrenia. Dr. Feigenson studies how this varies in the general population using optical illusions, which trick the visual system using cues that misrepresent the size, shape, or distance of a specific object.

Predictive reasoning

Our brains use predictive reasoning when forming perceptions of the world around us, using memories to inform current judgments. This occurs in many cognitive and perceptual activities and is believed to be impaired when people suffer from delusions, or strongly held ideas that are not supported by factual evidence. Dr. Feigenson is interested in studying this in the general population, employing such tools as the hollow mask illusion and a jumping to conclusions task.

Biomarkers

A hot topic in psychiatric research is how we can use biomarkers to identify or predict states, conditions, or disorders. In the mental health field, increasing attention is being given to things such as inflammatory molecules, circulating antibodies, and cortisol levels, and how they could relate to the onset, development, and progression of specific disorders. Dr. Feigenson is interested in how biomarkers can be used as markers of states like stress and altered perceptual states.

Cognitive Training

Can training in one domain of behavior improve performance in a separate domain, if the two share a common biological mechanism? To this extent, Dr. Feigenson hopes to use perceptual organization tasks to see if improving performance in visual areas can simultaneously improve performance in auditory areas (and vice versa). Another question that arises from this line of investigation is what other mechanisms exist to improve mental processes involved in perception and cognition?
