| Edward F. Malagodi Symposium One: Experimental Analyst, Philosopher, Radical Behaviorist |
| Monday, May 30, 2005 |
| 1:30 PM–2:50 PM |
| International South (2nd floor) |
| Area: EAB; Domain: Basic Research |
| Chair: Jeff Kupfer (Jeff Kupfer, PA, and Florida Residential Solutions, LLC) |
| CE Instructor: Jeff Kupfer, Ph.D. |
| Abstract: These symposia are devoted to celebrating the works of E. F. Malagodi (1935 – 1996), and recognizing his contributions to the science of behavior. The contributing speakers are behavior analysts who were graduate students under Malagodi, and colleagues that worked closely with Malagodi at the University of Florida. The two symposia are classified into areas in which Malagodi had significant influence upon behavior analysis. The first symposium consists of four papers devoted to human and non-human experimental analyses in sensory and conditioned reinforcement, and experimental psychopathology. The second symposium consists of three papers and a discussion devoted to Radical behaviorism, extending behavior analyses to cultural issues, and Malagodi’s impact on the development of graduate training at the University of Florida. |

| Shedding Light on the Problem of Conditioned Reinforcement |
| RONALD F. ALLEN (Ivy Street School), Jeff Kupfer (Jeff Kupfer, PA) |
| Abstract: A series of experiments with pigeons explored stimulus conditions under two- and three-link second-order chained schedules of food presentation. In each study, illumination of a houselight during a component schedule produced rate enhancement effects in the component preceding it.This “houselight effect” had not been examined explicitly in previous studies; however, a review of the literature suggests uncontrolled houselight conditions may account for discrepancies between experimental findings. Kupfer, Allen & Malagodi (1980) conducted a replication of Stubbs (1972) study on conditioned reinforcement. Systematic manipulation of brief-stimulus presentations, both with and without the houselight illumination accounted for Stubb’s general. Results support the general notion that brief-stimuli paired with food presentation enhances response rates and generates patterns of responding similar to those generated when component schedules terminate with food delivery. |

| E. F. Malagodi's Work on Shock-Maintained Behavior: A Case History in Scientific Method |
| RAYMOND C. PITTS (University of North Carolina, Wilmington) |
| Abstract: In this presentation, I will review some of Ed’s work investigating the maintenance of behavior by the presentation of electric shock and use it to illustrate his experimental approach to addressing perplexing problems. |

| What's the Response Requirement Got to Do with It: Ed Malagodi's Contribution to the Nature of Adjunctive Behavior |
| ANNE S. KUPFER (Arizona State University) |
| Abstract: Adjunctive behavior is considered by some to be just another instance of either operant or respondent behavior. But to Ed, it was clearly different and worthy of a separate classification. The nature of adjunctive behavior and its relation to establishing operations and emotions will be discussed. |

| Back to the Future: E. F. Malagodi's Enduring Contributions to Token Reinforcement |
| TIMOTHY D. HACKENBERG (University of Florida) |
| Abstract: The field of token reinforcement was substantially enriched and refined by the work of Malagodi and students in the 1960s and 1970s. Prior to this, the laboratory study of token reinforcement had been conducted exclusively with chimpanzees as subjects and poker chips as tokens. Malagodi extended token reinforcement to a different species (rats) and a different token (marbles). But more importantly, Malagodi's research laid the groundwork for a systematic exploration of variables operating within a token reinforcement system, while at the same time, established connections to broader issues in the analysis of behavior--conditioned reinforcement, chaining and temporal organization, response units, to name a few. In this talk I will summarize Malagodi's enduring contributions to the field of token reinforcement, including some recent research to illustrate the extent to which his legacy survives on the contemporary scene. |
