Human Development


My research and teaching are interwoven so that the two activities reinforce each other and so that, to the greatest extent possible, the latest research findings are integrated into the courses I teach. Throughout my career, my research and teaching have revolved around a single broad theme: the scientific study of human cognition. I have concentrated most extensively on the development of cognitive processes in normal and atypical children, but I have also published considerable research on adult cognition and have taught widely in that area. Thus, my vitae is sprinkled with publications in outlets such as Journal of Experimental Psychology and Journal of Memory and Language, as well as the familiar developmental outlets, such as Child Development, Developmental Psychology, Developmental Review, and Journal of Experimental Child Psychology. In recent years, my research and teaching have also encompassed questions about how cognitive processes are affected by normal aging and by the diseases of late adulthood. This, in turn, has stimulated a research program in cognitive neuroscience. Across all of these areas, a particular focus has been the relationship between memory processes and higher reasoning abilities. After several years of research and teaching on the memory/reasoning interface, I began to develop, with the collaboration of my colleague V. F. Reyna, a general model of how memory influences reasoning and how reasoning influences memory, which is known as fuzzy-trace theory. Fuzzy-trace theory, which seeks to explain some of the most counterintuitive aspects of memory and reasoning, is now widely used by investigators in fields such as forensic psychology, judgment and decision making, and human memory. The theory has become standard fare in undergraduate and graduate courses and can be found in freshman psychology textbooks.

All of my research and teaching have been characterized by commitments to (a) rigorous research that relies on the experimental method, (b) the application of mathematical models, and (c) the development of predictive theories of cognition. Concerning (a), when it comes to the gain in reliable knowledge that can be derived from research, the experimental method is without parallel. Although important information can be gained from descriptive correlational investigations, especially in the early stages of research, only carefully-counterbalanced studies that are conducted under controlled conditions are able to separate the factors that influence cognition from each other and to establish the cause-effect relations that are essential to theoretical interpretation. For that reason, virtually all of my research has been characterized by hypothesis-driven experimental designs. Concerning (b), a standard conundrum in research on cognitive functions is that the procedures that are used to measure human cognition, from the simplest attentional task to the most complex reasoning task, are not process-pure. That is, performance on such tasks is invariably due to a mixture of contributing cognitive processes. Therefore, by definition, the respective contributions of those processes cannot be separated, let alone quantified, using task performance as the sole source of dependent variables. To accomplish separation and quantification, it is necessary to implement the target processes in a mathematical model that is defined over the task in question and to estimate the model's parameters from performance. Because it is the parameters that carry information about the target processes, data analysis then centers on estimated values of those parameters, rather than on task performance. This, in turn, allows theoretical hypotheses to be directly evaluated, rather than indirectly evaluated under weak measurement assumptions. An additional strength of model-based research that redounds to the benefit of knowledge gain is that theoretical ideas must be sharpened to a fine edge before they can be embedded in mathematical models. In light of all these advantages, there is no cognitive task that I have studied extensively for which I have not also developed relevant mathematical models. A few examples include Markov models of recognition and recall, Markov models of logical and scientific reasoning, multinomial models of mathematical reasoning, and multinomial models of false recognition and recall. I am now coupling mathematical models with neuroscience methods to achieve process separation at the level of brain activity. Last, concerning (c), one of the abiding limitations of cognitive theories is that they emphasize explanation at the expense of prediction. That is, what counts as an acceptable theory is a body of assumptions that can cover available research findings, hopefully with due regard to parsimony, with little consideration being given to whether new and surprising results fall out of those same assumptions as predictions. However, explaining data is the easy part, and experience has shown that it is possible to formulate multiple competing explanations of any set of data. The more formidable part of theorizing is developing a set of assumptions that will also predict novel findings that would not have been envisioned without those assumptions. That is the type of theorizing that I have stressed in my research and teaching, and fuzzy-trace theory is a prime example. In addition, it is the emphasis on predictive theorizing that is responsible for the fact that my experimental work has so often been concerned with counterintuitive findings--for instance, the cognitive triage effect, the false persistence effect, the mere-testing effect, the memory-independence effect, the memory-interference effect, the overdistribution effect, and the phantom recollection effect.

Report all public service and public engagement beyond that of the formal Extension programming

Throughout my career, I have maintained strong commitments to public service activities that implement the latest scientific knowledge. Regardless of the age range that has occupied my attention during particular phases of my career, I have devoted continuing attention to the application scientific findings to real-world problems in human cognition. For some years, this focus took the form of intense work on elementary-school mathematics and science curricula. As part of that work, I made contributions on topics such as the types of number concepts and arithmetical operations that are easiest for young children to learn, the order in which such skills should be introduced in classrooms, and the instructional methods that promote learning of such skills. Following that work, I turned to applications of cognitive research to instruction in high-technology teaching environments. Here, I made contributions to early understanding of computer-based learning, including learning via proprietary instructional software, web-based learning, and distance learning via video conferencing. Most recently, I have devoted much effort to applications of research on cognitive processes to problems in the law. In that arena, I have made contributions to topics such as criminal interrogation, criminal confession, false memory in psychotherapy, investigative interviewing of children, witness competence, and eyewitness identification. I have also provided expert scientific information on such research to courts in many states and have taught such information to varied groups of legal professionals (e.g., to bar associations, to judicial associations, to teams of trial officers of the Judge Advocate General, to teams of private attorneys), as well as to graduate students.  I routinely advise state and federal courts on the reliability of scientific evidence through the mechanism of Frye and Daubert hearings.  As a result of my activities in the legal sphere, fuzzy-trace theory has become a model that is widely used to evaluate the reliability of memory evidence by courts in the United States.
