Behavioral Contingency Analysis: A formal symbolic language for the analysis of complex contingencies

This PDF of the PowerPoint presentation requires no special background and is designed to be accessible to anyone. It explains the purpose and features of the formal language for codifying and analyzing behavioral contingencies and illustrates some of its potential areas of application. The Table of Contents on slide three lists the general topics that this presentation covers. More detailed and complete presentations of the language and its applications can be found in the published papers below.

Anatomy of Deception: A Behavioral Contingency Analysis
F. Mechner, 2010.

Deception, a basic biological function of most forms of life, is analyzed in terms of  its behavioral contingency components.  The analysis focuses on types of deception that are prevalent in human affairs, including interpersonal relationships and economics, and shows how diverse forms of deception can be categorized according to whether they are disadvantageous to the deceived or not, direct or indirect, based on misperception, non-perception or misprediction, whether the agent of deception is animate or inanimate, and, if animate, whether the deception is intentional or unintentional, gradual, or sudden.

Analyzing Variable Behavioral Contingencies: Are Certain Complex Skills Homologous With Locomotion?
F. Mechner, 2009.

This is the PDF file of the published paper:
Mechner, F. (2009). Analyzing variable behavioral contingencies: Are certain complex skills homologous with locomotion? Behavioral Processes, 81, 316-321.
It shows how behavioral contingency analysis can demonstrate that locomotion behavior is the phylogenetic ancestor and biological homologue of certain complex verbal processes such as reading or copying.  More broadly it illustrates how behavioral contingency analysis can show how behavioral phenomena that may seem to be unrelated actually involve the same underlying behavioral processes.

A more detailed treatment of the subject of this paper, with an expanded range of examples, is provided in the paper "Applications of the Language for Codifying Behavioral Continencies," available below.

Applications of the Language for Codifying Behavioral Contingencies
F. Mechner, 2008.

This is an expanded version of the paper "Behavioral Contingency Analysis" published in Behavioral Processes (PDF version available above).  It presents a formal language for the codification of behavioral contingencies, and illustrates the application of this language to the analysis of behavioral contingencies in such diverse fields as economics, law, business management, clinical psychology, education, public affairs, games, and military planning.

The paper represents a comprehensive update of the Mechner Notation System presented in “A notation system for the description of behavioral procedures" (JEAB, 1959), and the 1966 Weingarten and Mechner paper “The contingency as an independent variable of social interaction,” both of which are available for downloading on this website.

Review of "In Search of Memory: The Emergence of a New Science of Mind" by Eric R. Kandel
F. Mechner, 2008.

This is the PDF file of the published paper:
Mechner, F. (2008). An invitation to behavior analysts: Review of In Search of Memory: The Emergence of a New Science of Mind by Eric R. Kandel. Journal of the Experimental Analysis of Behavior, 90, 235-248.
It discusses the reasons why the study of this book can be valuable to behavior analysts.  It analyses and attempts to bring into perspective criticisms that have been leveled against certain aspects of the language used by some neuroscientists, opportunities for productive collaboration between behavior analysts and neuroscientists, the value of heuristics put forward by Kandel for locating important research problems, and the lessons that can be gleaned from the book for recognizing potentially great achievers and for producing good scientists.

Summary of Neuroscience Information in "In Search of Memory: The Emergence of a New Science of Mind" by Eric R. Kandel
F. Mechner, 2008.

This summary of neuroscience information covered in Eric R. Kandel’s book In Search of Memory: The Emergence of a New Science of Mind is presented in a dry style for reference purposes only. It omits many of the explanatory details and colorful background and historical information that can be found in the book.

Learning and Practicing Skilled Performance.
F. Mechner, 1994. The Mechner Foundation website.

This book develops a theory and technology of skilled performance, based on research in psychology and physiology. Examples are drawn from various performance disciplines, with special emphasis on pianism. It is 101 pages in length and can be downloaded.

Review of "Blindfold Chess: History, Psychology, Techniques, Champions, World Records and Important Games" by Eliot Hearst and John Knott
F. Mechner, 2010.

This review discusses the book as not only the definitive work on the topic, but also an important examination of blindfold chess as it relates to perception and imagery research.  The review also proposes a new way to measure skill and knowledge in choice situations, loosely based on a 1951 proposal by Claude Shannon.  The usual measures of skill and knowledge reflect practical performance results, but such measures are typically confounded by extraneous variables.  The proposed system provides a pure, general measure of any type of knowledge or skill that involves choice -- a "power" measure based on the determination of the shortfall from a theoretical maximum.

The Revealed Operant: A Way to Study the Characteristics of Individual Occurrences of Operant Responses
F. Mechner, et al., 1994. Cambridge Center for Behavioral Studies Monograph Series.

The "revealed operant" is intended as a laboratory research model of any operant response. Its purpose is to permit the internal structure and properties of operants to be recorded and studied. With Commentaries by Donald M. Baer, M. Jackson Marr, John A. Nevin, and Thom Verhave. DOWNLOAD

What Are the Effects of Reinforcer Presentations?
F. Mechner, 1994. Cambridge Center for Behavioral Studies Monograph Series.

Chapter 9 of the monograph The Revealed Operant: A Way to Study the Characteristics of Individual Occurrences of Operant Responses (available in full above). This chapter develops the thesis that the usual effect of a reinforcer is not to increase the strength of the preceding behavior, but rather to perpetuate its direction of change. The Foundation is currently conducting a research program to address this issue experimentally, using shaping procedures for various types of revealed operants. DOWNLOAD

Methodological Points for Behavioral Scientists
F. Mechner, 1993. The Mechner Foundation website.

This paper discusses the status of hypothetical constructs, models, and explanatory fictions in science generally, and in psychology in particular. It explores possible reasons why the problem is particularly insidious in the behavioral sciences. DOWNLOAD

A New Approach to Programmed Instruction
F. Mechner, 1977. The Mechner Foundation website.

Programmed instruction was defined in the early 1960s as using active response by the learner, immediate confirmation of correct responses, and successive approximations towards the knowledge to be learned. This paper, written in 1977, proposes some newer and presumably more effective techniques of programmed instruction and the theoretical justification of those techniques. DOWNLOAD

The Contingency as an Independent Variable of Social Interaction
K. Weingarten & F. Mechner, 1966. T. Verhave (Ed.), Readings in the experimental analysis of behavior.

This paper shows how the Mechner notation system can be applied to behavioral contingencies that involve the interactions of two or more individuals in such dynamics as cooperation, competition (both for individuals and groups) economic interactions, blackmail, flattery, insults, etc. DOWNLOAD


MUSIC

Mechner's involvements with music have included piano performance, composition, study and analysis of certain piano pieces in the classical repertory, and the theory and technology of effective practicing.
