Biography: 

Dr. Brooks came to Denison in 2000 and teaches courses in learning and conditioning, animal cognition, and related topics. His research interests focus on the basic learning and memory processes that influence treatment (e.g., of anxiety or substance abuse disorders) and the relapse of unwanted behaviors after treatment. He is interested in understanding those processes that can change behaviors motivated by emotions and/or biological need. He and his students have developed techniques for reducing and even eliminating some instances of relapse modeled in the laboratory. Some of Dr. Brooks' other interests include addiction, the history of psychology, and the role of diet and thought in mental health.

Research: 

Pavlovian Conditioning, Memory, Emotion, and Relapse

My research program involves basic research on the learning and memory processes that modulate emotionally- and motivationally- significant experiences, and the behaviors that accompany those experiences.  I am especially interested in the use of animal models to better understand the learning and memory processes that underlie instances of human relapse of problematic behaviors with emotional components (e.g., substance abuse, anxiety, depression).  Believe it or not, the methods of Pavlovian conditioning are uniquely suited to the study of these and any emotion-based behaviors.

Since Ivan P. Pavlov's time in Russia (circa 1890-1925), psychologists and other scientists have come to realize the fundamental importance of Pavlovian (classical) conditioning for the development of and change in many involuntary ("non-conscious" and other) responses experienced by humans and other animals.  These responses are the result of Pavlovian conditioning, and include heart rate, blood pressure, respiratory, and perspiration changes; emotional reactions like anxiety, fear, excitement, frustration; drug tolerance, withdrawal and craving; and motivational influences on many voluntary behaviors such as feeding, competition, reproduction, and pleasure-seeking activities, to name just a few.

An increasingly popular idea about Pavlovian conditioning is that it results in the formation of memories involving the events that are present in an organism's environment when they have emotionally-significant experiences.  My research focuses on what the content of those memories is, and what happens to those memories (e.g., how memorable they become) usually at some time after they have formed.  Sometimes various different memories can interact, and in some cases, the memory of a particular experience can be retrieved more or less well compared to other memories. This disparity in the ability to retrieve certain memories can produce dramatic changes in behavior.

My research is directed at three interrelated fronts:

  1. The study of animal models of relapse in humans.  One of the more interesting implications of our research here is that clinical relapses (of substance abuse, anxiety-disorders, depression, and so on) occur in part because crucial information learned during the treatment of a disorder is forgotten rather readily after the formal course of treatment ends (i.e., relapse is likely when a period of time has passed, or the setting changes, following treatment).  Using a model involving rats as subjects, my research has shown that laboratory instances of relapse can be reduced or eliminated by straightforward memory retrieval techniques.  (The implications of this research for human treatment are rather important.  Psychology has developed fairly good technologies for the treatment of common psychological disorders like anxiety and depression, but unfortunately, relapse rates post-treatment are disturbingly high.  More information is needed about why relapses occur, and how they can be minimized or completely prevented.) My students and I have found that the memory processes that underlie relapse and its reduction are similar in both aversive and appetitive motivational systems, i.e., when animals form initial memories about either "positive" or "negative" experiences.  One objective of our research is to continue to study the basic memory mechanisms that contribute to various types of relapse, and those that may contribute to reducing relapses.
  2. Our research has implications for a basic understanding of conditioning and memory involving important emotional events.  Some contemporary theories of conditioning and memory can explain the instances of relapse and their reduction that we have been studying intensively (e.g., hierarchical associative learning theories about occasion setting and contextual control).  Other theories cannot.  The theories that suggest explanations are relatively straightforward neural network models that can simulate many conditioning effects.  My students and I conduct ongoing tests of these theories using experimental designs that we hope will advance our understanding of not only the clinically-relevant relapse phenomena, but of the general memory processes involved in motivation & emotions.
  3. Recently, I have begun a project to study alcohol tolerance, withdrawal, and relapse, with the intention of influencing the probability or magnitude of craving-related responses and relapses that motivate an individual to resume alcohol use/abuse.  I believe this work has direct relevance to human substance abuse patterns.  There is always interest in determining whether learning and memory processes shown with nonhuman animals also apply to human experience, behavior, and memory.  I am beginning to investigate drug-use related relapse-like effects in human memory, with particular interest in discovering whether relapses might be reduced by reminder treatments analogous to those I've established with other methods.

I would be happy to talk with students about any aspect of these intriguing and challenging areas of research, and related topics.  Please contact me for questions or comments about my research program.

Biography: 

Dr. Chin-Parker began teaching at Denison in the fall of 2004. He teaches Introduction to Psychology, Research Methods, Cognitive Psychology, Research in Cognitive Psychology, and a seminar titled “Creativity and Cognition”. When he is not in the classroom (or his lab), Dr. Chin-Parker enjoys spending time with his family, running on the trails of the Denison Biological Reserve, and attempting to play the guitar.

Research: 

My research program focuses on the interplay between conceptual knowledge and experience: Conceptual knowledge plays a critical role in shaping the interactions we have with the world, and it is correspondingly shaped by those interactions. Reflecting this interplay, I have adopted two perspectives that frame my research:

  • Access to relevant conceptual knowledge can change the processing associated with a given behavior, and so cognitive functions (e.g. category learning and explanation) that tap into conceptual knowledge should be studied in situations where relevant knowledge is available.
  • The acquisition of conceptual knowledge, or category learning, should be studied in context. People learn about categories of items as they complete other tasks – the processing associated with these tasks, as well as the goals of the individual, affect what is learned about the categories to which the items belong.

By taking this stance, I am able to examine several important issues that have been overlooked by much of the research in the area. Because there is a tendency in experimental work to isolate cognitive functioning in order to get a “cleaner” view of the processes involved, we sometimes inadvertently change the nature of the processing by removing it from the context in which it typically occurs. This is especially a concern when studying cognitive processes that link up with conceptual knowledge.

Ultimately, my research interests stem from a desire to better appreciate what it means to “understand”. I consider our behaviors, especially cognitive processes, to be largely dedicated to meaning making – seen in the constant questions of a three year old and extending to the way that we reflect on our world and ourselves through art, literature, science. I have selected to study the cognitive processes and structures that underlie the acquisition and use of conceptual knowledge because they are so intimately tied to how we make sense of the world.

Biography: 

Prof. Heft has been on the Denison faculty since 1976. His graduate training was in an interdisciplinary program concerning the relationship between psychological processes and the environment. At Denison, he has been a recipient of the Charles A. Brickman Award for Teaching Excellence. He has also been elected as a Fellow in both the American Psychological Association and the American Psychological Society. Dr. Heft serves on the Editorial Boards of the journals "Environment & Behavior" and "William James Studies," and he is the Book Review Editor for the "Journal of Environmental Psychology." He teaches courses in environmental psychology, history and systems of psychology, and cultural psychology.

Research: 

Prof. Heft's scholarly interests primarily concern topics in the related areas of environmental and ecological psychology. His book "Ecological Psychology in Context" (LEA, 2001) elucidates the theoretical and philosophical foundations of ecological psychology and some of its connections to current work in cultural psychology.

Much of his research has examined the process by which humans find their way through the environment, with its focus on identifying the environmental information that is utilized in learning a path or route. On-going research in this vein is attempting to understand how this route knowledge can be employed to promote understanding of the overall configuration of a place. He has also conducted research in the past on the perception of affordances (i.e., the perceived functional meaning of objects and environmental features), the development of children's navigational skills, environmental aesthetics, and the effects of noise in the home on cognitive development.

First, I am interested in gender differences in a variety of social behaviors, as well as differences in the social evaluation of women's and men's behavior.  My research in this area has examined the content of attitudes toward men and women, gender differences in interaction patterns, and the appropriateness of women's and men's emotional reaction to life events.  My current research projects focus on the social consequences of women's and men's emotional expressions during job interviews and political campaign speeches.

Social Influence Processes

My second line of research addresses the social influence processes that individuals and groups use to change others' opinions and behavior.  I am particularly interested in the conditions under which a minority opinion holder can influence the opinion of a majority, and the social influence processes by which a minority and majority opinion holders exert their influences.  My recent work on these issues has been in the context of psychology and law.

Personalities of Attorneys

The third line of research examines the personality characteristics of attorneys.  In particular, I am interested in individual differences between trial and non-trial attorneys as well as gender differences.  To examine some of this research click here. We have developed a webpage that summarizes the research we have conducted on this topic and contains a Psychology and Law Research Guide to articles about various topics in the field of psychology and law .

Research Interests

My research interests are focused in two general areas of behavioral neuroscience and psychopharmacology.  The first area is concerned with how animals' behavioral responses to stimulant drugs such as amphetamine might abe modified by previous drug experience.  This work has implications for models of “addiction,” which maintain that early experiences (such as stress) may make an organism “at risk” for later stimulant addiction.  Secondly, I am interested in the historical and cultural contributions to current drug policy, and the role of science versus popular culture in defining public policy regarding licit and illicit drugs.

Biography: 

Dr. Przybyla is a social-personality psychologist specializing in the study of human sexual behavior.  His research interests in this area include interpersonal attraction, the consequences of physical attractiveness, and contraceptive education.  Dr. Przybyla has been at Denison since 1985, and teaches a range of courses including social psychology, human sexuality, and industrial/organizational psychology. Dr. Przybyla also is the Director of Denison's Organizational Studies Program.

Research: 

My major research program is in morphological characteristics and their consequences in the area of interpersonal attraction.  Broadly speaking, morphological characteristics may be conceptualized as physical attractiveness cues -- facial and otherwise.  A current primary focus of my work is cranial hair loss in men.  I am interested in continuing my work in this area and would be particularly interested in working with students who have expertise with Photoshop.  Research projects into other physical attractiveness cues are also of interest.

A second area of interest is that of gender and sexuality.  I am interested in comparing the experiences of men and women in areas ranging from contraception and abortion, to pregnancy and childbirth, to erotica and coercion, to sexual dysfunction. I would be interested in research extending either of the preceding content areas into the field of organizational behavior (e.g., romantic attraction in the workplace).
