| The Learn-by-Doing Principle |
| Domain: Theory |
| HAYNE W. REESE (West Virginia University) |

| Abstract: “Learning-by-doing” has been a precept and a principle for thousands of years; it has had many proponents, including Plato, Thomas Hobbes, English and Spanish epigrammatists, Karl Marx and Mao Zedong, cultural anthropologists, Montessori, John B. Watson, and B. F. Skinner; and it has been advocated in many ways, including learning by doing, instruction versus discovery, direct experience versus book-learning, proof upon practice, and the practice-theory-practice dialectic. I will discuss various versions of the principle, with examples, to establish what it means; modifications of the principle such as instructed learning-by-doing and a role of reasoning; and possible explanations of its effectiveness. |

| Juvenile Anxiety: An Animal Model of Adolescent Fear-Conditioning Acquisition and Extinction |
| Domain: Experimental Analysis |

| Abstract: Behavior analysis has traditionally eschewed guiding metaphors to describe behavioral development. As an alternative to these metaphorical developmental stages, it has offered the description of systematic patterns of contingencies throughout the lifespan. Nonetheless, many contingencies result in distinctly different functional relationships depending on the age of the organism: this fact has been frequently overlooked within the Experimental Analysis of Behavior, where the overwhelming majority of experiments are carried out with adult organisms. The shortcomings of this approach are illustrated with data comparing the acquisition and extinction of fear-conditioning in adolescent and adult rats. Furthermore, we explore the use of the concept of establishing operations to describe these developmental changes. |
