Background:
 
I have a Ph.D. in behavioural neuroendocrinology during which I investigated the influence of in utero, dietary, and social factors on time to sexual maturity in developing females. This work is published in journals such as Reproduction, Physiology & Behavior, Reproduction, Fertility and Development, Hormones and Behavior, and Hormone and Metabolic Research.
 
Teaching:
 
My passion for teaching is driven by my interactions with the enthusiastic and inquisitive students I meet on a regular basis. I teach a variety of courses covering topics such as animal behaviour, the physiology and endocrinology of reproductive behaviour, and neuropsychology (see complete list below).

Current Research:
 
My research interests explore ways through which the undergraduate student experience is enhanced by incorporating experiential education in large enrollment courses. As part of a multi-institutional initiative, I am also investigating the impact of the newly implemented Fall Break on student mental health. I have received funding from the Forward With Integrity Initiative at McMaster University to create an online strategy to disseminate information about community-engaged education for Instructors on McMaster campus and beyond. I am a Research Fellow at the McMaster Institute for Innovation and Excellence in Teaching and Learning (MIIETL) and am in current collaboration with this institute to investigate the impact of community-engaged education on academic engagement and development in undergraduate students.

My research questions investigate:

1. The influence of community engaged education on student development.
2. Changes in stress hormones due to a mid-semester break in university students.                       
3. Practical uses of e-Portfolio technology to enhance reflective thinking and student engagement.

Our research has been concerned with the general area of Pavlovian conditioning, especially the contribution of such conditioning to physiological and behavioural regulation. Recently, we have been applying conditioning concepts to the understanding of the judgment of contingent relationships.  In this research we are attempting to integrate  associative and signal detection approaches.

The specific features of many sounds that we hear and the significance attached to these sounds are unique for each individual and cannot be anticipated by a genetic code. To meet the challenge of uniqueness, the brain contains mechanisms for neural plasticity that tune auditory neurons to represent the sounds that are meaningful to us. We use brain imaging and acoustic training methods to understand how neural plasticity modifies sensory maps in children and adults and to uncover the principles and mechanisms involved.  The knowledge gained from laboratory studies is applied to understand how plasticity sculpts foundations for auditory skills in professional musicians and in children receiving music training and how it may generate tinnitus (chronic ringing of the ears), an auditory deafferentation syndrome affecting quality of life for millions of individuals world-wide.  By understanding tinnitus we gain insight into how the brain generates the sensation of sound.

My students and I have been studying the role of social learning in development of adaptive patterns of behaviour in animals as diverse as Norway rats and Japanese quail. The results of our experiments provide evidence of an important role for social learning in development of behavioural repertoires. Such evidence is important because, in the endless arguments over whether instinct or individual learning guides development of behaviour in adaptive directions, the possibility that animals might learn what to do as a result of interaction with more experienced conspecifics was ignored. We have been kept busy filling the gaps both providing evidence that, for example, animals can learn where to eat, what to eat, and when to eat from their fellows, and analyzing behavioural and sensory processes supporting such social learning.

Dr. Galef is a Fellow of both the Canadian and American Psychological Associations as well as the American Psychological Society, Animal Behavior Society and American Association for the Advancement of Science. He is co-founder, and was, for 8 years, co-organizer of the Winter Animal Behavior Conferences. Dr. Galef was a member of the boards of directors of the International Society for Developmental Psychobiology, the Animal Behavior Society and the McMaster Museum of Art, and has served on the editorial boards of 12 journals including the Journal of Comparative Psychology and Animal Behaviour of which he was Executive Editor from 1998 to 2001. He has co-edited three books (Social Learning in Animals: the Roots of Culture, Social Learning : Psychological and Biological Perspectivesand Behavioral Aspects of Feeding) and two special issues of journals. He is the author of more than 250 published papers. Dr. Galef has been a Visiting Professor in Panama, Israel, Australia and the United States and is currently Emeritus Professor of Psychology at McMaster University in Hamilton, Ontario and President of the Animal; Behavior Society.

Lee left a lasting mark

I just saw this news, searching for some papers of his to pass on to some colleagues. I lost touch with Lee, but I always expected to see him again.

New contributions appear to be closed, so I am writing my tribute as a response to the most appropriate post that I can find in this set…

================

I studied psychology with John Vokey, in the late 1970?s, early 1980?s. I worked in a different sub-area (psychophysics) but Lee took me under his wing. He allowed me to do mentored research in his lab. He joined my doctoral committee and critiqued my ideas and, especially, my methodology.

I thought I knew a lot about the philosophy of science when I came to McMaster. I had studied philosophy as an undergrad. Lee gently, but enthusiastically, made me realize how little I knew and what fascinating ideas were on my horizon. Kuhn was a starting point. But his approach to nonanalytic concept formation was an education in itself in questioning one’s assumptions, holding the “obvious” up to scrutiny, and thinking through how to create a credible critique of things that everyone “knows”.

Lee was remarkably patient with me, before I graduated and after. He was always helpful.

As a teaching assistant for his cognition course, I discovered that he was sensitive, perhaps too ready to accept (or worry about) criticism (especially criticism of his teaching). I learned a lot about the humility of teaching from him, the art of being the authority in a class while recognizing that there is much to improve and the students can and will point that out and deserve your attention when they do. I apply that teaching every day, now, as a teacher myself.

Lee was one of the small set of teachers who left a lasting mark on my career and my persona. I will miss him forever.

A great scientist

I only met Lee in person once (in Cambridge in around 1999, when he attended a conference I was co-organizing), but I’m a long-time follower of his work, and he provided a number of signed, very useful and wonderfully full, reviews of my articles. It’s very sad to hear of his death.

This post was submitted by Andy J. Wills.


Lee was my mentor before the word was used for this relationship

I was an assistant professor at McMaster 1970-74. I have always said that, although I did teaching and earned my salary, it was like doing what we would now call a post-doc, under Lee’s supervision. He rounded out my education in psychology. We talked constantly; he was across the hall most of the time I was there. I came to think of him as one of the smartest people I knew. Also underappreciated. Not UN-appreciated, but he certainly should have been more famous than he was. In part, he didn’t try. He just wanted to find the truth.

We also talked politics, constantly. He was always arguing the conservative side, because I was farther left than I am now. Now I think we would agree about political matters. I also learned a lot from him about Canada. In many ways I’m sorry we did not stay there. Although I was out of touch with Lee for many decades, the thought that he isn’t around any more is a sad one.

Academic History

The general topic I am interested in is concept learning and the process of gaining sensitivity to complex structure. This general topic breaks down into several specific areas. Medical diagnosis. When reading a textbook list of the rules for diagnosing a disorder and looking at the illustrations of the key features, it is hard to believe that diagnosis of the disorder could be difficult. The experience, however, is very different. Our research program has been aimed at understanding some of the sources of difficulty.

1. Difficulty in noticing the obvious. We have two lines of evidence that the perception and reporting of supposedly obvious features of patient appearance is strongly influenced by contextual factors. Both experts and students gained 20% in diagnostic accuracy by having textbook examples of features verbally described for them. Both experts and students reported from 15 to 30% more of these features when the correct diagnosis was suggested to them. The informal report by experts and students alike was that they simply had not noticed features that then seemed clear after they were pointed out. We believe that this is a major characteristic of many medical stimuli, and one that results from the large number of potential categories, the presence of many variations of normal features, and the relatively low redundancy of these stimuli. (Norman, LeBlanc & Brooks)

2. Disadvantage of Searching Medical Stimuli without a Diagnostic Hypothesis. Students who were instructed to avoid making any diagnosis until after they had worked down a list of all potential features for the disorders under consideration came to 1/3 fewer correct diagnoses than did a group that was asked to make a diagnosis first and then report the features. The "feature first" subjects informally reported that they wound up with so many potential features that they became confused with incompatible possibilities when confronting the list of diagnoses. (Brooks, Colle, Hatala & Norman)

3. Influence of similar prior instances. Different prior cases may come to mind under different circumstances. The prior cases that do come to mind might help in guiding the search for relevant features. The variability provided by depending on a wide variety of prior cases might help to explain big variations in the reliability of diagnosis. (Brooks, Allen & Norman, 1991; Norman, Brooks, Coblentz, & Babcook, 1992).

Implicit structure. Without deliberately trying to, people often become sensitive to the structure of a domain, such as musical style or even the design of an experiment in which they participate. We have documented a strong nonanalytic contribution from prior episodes in this kind of learning.

1. Abstract analogies in artificial grammars. In an artificial grammar experiment subjects are given sets of consonant strings to memorize. They then are told that these strings were generated by a complex set of rules and are asked to judge whether new strings are or are not consistent with those rules. Subjects perform well above chance on this even though they claim to not have been looking for rules while memorizing. We have shown that a major portion of this ability is due to similarity between test strings and particular training instances. even when the literal surface elements are changed. Reber (1969, 1989a) and Mathews et al (1989), in experiments on learning artificial grammars, reported good transfer to letter strings consisting of letters not used in the training stimuli, provided that the same grammar generated both training and transfer strings. They conclude from this that the transfer predominantly relies on abstract knowledge. We report an experiment showing that much of the transfer to "changed letter set" strings is due to abstract similarity between test strings and specific training stimuli. That is, a string such as MXVVVM could be seen as similar to BDCCCB without implying that regularities common to a large number of training items had been abstracted. We conclude that reliance on an abstract (relational) analogy to an individual item must be distinguished from reliance on knowledge of the structure of the grammar abstracted across many training items (Brooks & Vokey, 1991).

2. Learning the experimenter's design. One premise of the artificial grammar literature is that people are continually gaining sensitivity to the structure of the world around them. In this paper we demonstrate that this sensitivity to structure extends to general memory experiments as well as the experiments deliberately designed to investigate structural learning. Rules that experimenters use to select words for memory experiments, such as frequency, length and grammatical class, produce consistencies to which subjects can become sensitive. Replicating the key results from the tacit learning literature, subjects in our experiments discriminated new words consistent with the experimenters' selection rules from inconsistent words, even when they could not describe those rules. The results also reveal a close relation between the information underlying recognition memory and classification judgments. In particular, a "mirror effect" (Glanzer & Bowles, 1976) is found with both tasks. (Higham & Brooks, 1997)

Coordination of analytic and nonanalytic knowledge. One of the overarching themes of research on natural concepts over the last 25 years is that our knowledge of the world is generally inexplicit: We judge items to be members of categories and anticipate their properties with reference to category prototypes or by comparison to previously experience instances of the category. However, in laboratory experiments, people persistently look for and use rules. Even some of the evidence that was originally taken to support the use of instances can be better fit by models that assume people are seeking rules (Nosofsky, Palmeri & McKinley's RULEX model). This discrepancy between the observed behavior of people in the laboratory and their inferred behavior in the world is, in our view, the major issue that need resolution in this field.

1. Identification in the service of use: Most people seem to believe that natural categories have perfectly predictive defining features. They do not easily accept the family resemblance view that the features characteristic of a category are not individually consistent enough to act as a simple rule. But common categorization tasks in the laboratory do not produce this "simpler than it is" belief. If there is not a simple classification principle in these tasks, the subjects know that fact and can report it. We argue that most laboratory tasks using family resemblance categories do not result in the everyday "simpler than it is" belief because the stimuli and the tasks encourage analysis of identification procedures during training. In order to simulate the learning that occurs under many natural circumstances, we describe a procedure, diverted analysis, in which the subjects' analytic abilities are diverted from the way in which the stimuli are identified to the use to which those stimuli are to be put. This procedure has the effect of providing a special role for "family resemblance" data structures, unlike the situation with more analytic training procedures. We also suggest that the informational descriptions of the stimuli commonly used in laboratory tasks are better suited to describe the subjects' analytic behavior than their impressions of consistency that are critical to their belief in the existence of perfectly predictive features. Finally, we discuss the prevalence of "diverted analysis" in everyday categorization tasks.

2. The erosion of analytic control of classification: One hypothesis we entertained was that possibly people originally developed rules (attention to salient predictors) to guide classification, but that with practice, they would start relying more on similarity to prior, well known instances. This process of retrieval would likely be easier, faster and generally yield the same answers as the rules, since the more similar prior items would probably be in the correct category. To investigate this, our participants received a classification rule and practice classifying a set of stimuli. Test stimuli included items very similar to training items, with expectation of observing a shift from classification by rule to greater reliance on similarity. However, the only similarity effect occurred by generating false recognitions, which went down with practice. Otherwise, people applied the rule to any items they recognized as new, even though they were slowed at applying the rule than they were in categorizing the new items they mistakenly thought were old. Variables ineffective in producing the shift include: Increasing practice, training with many close variants of category members, confounding many salient features with category membership. If our original hypothesis had been correct, it would have helped to explain the general discrepancy between laboratory performance and inferred behavior in the world.
