Green, Leonard; Myerson, Joel; Calvert, Amanda L. – Journal of the Experimental Analysis of Behavior, 2010
Pigeons' discounting of probabilistic and delayed food reinforcers was studied using adjusting-amount procedures. In the probability discounting conditions, pigeons chose between an adjusting number of food pellets contingent on a single key peck and a larger, fixed number of pellets contingent on completion of a variable-ratio schedule. In the…

Lagorio, Carla H.; Hackenberg, Timothy D. – Journal of the Experimental Analysis of Behavior, 2012
Pigeons were given repeated choices between variable and fixed numbers of token reinforcers (stimulus lamps arrayed above the response keys), with each earned token exchangeable for food. The number of tokens provided by the fixed-amount option remained constant within blocks of sessions, but varied parametrically across phases, assuming values of…

Mazur, James E. – Journal of the Experimental Analysis of Behavior, 2012
Parallel experiments with rats and pigeons examined whether the size of a pre-trial ratio requirement would affect choices in a self-control situation. In different conditions, either 1 response or 40 responses were required before each trial. In the first half of each experiment, an adjusting-ratio schedule was used, in which subjects could…

Hrepic, Zdeslav – Physics Teacher, 2012
While we still do not have a definitive answer about the reason(s) for which birds stand on one leg, a list of suggestions has been offered both by expert ornithologists and amateur birdwatchers. We offer a perspective grounded in statics and rotational dynamics that has not been suggested in the literature. The discussion has implications for…

Eppolito, Amy K.; France, Charles P.; Gerak, Lisa R. – Journal of the Experimental Analysis of Behavior, 2011
Delay to delivery of a reinforcer can decrease responding for that reinforcer and increase responding for smaller reinforcers that are available concurrently and delivered without delay; acute administration of drugs can alter responding for large, delayed reinforcers, although the impact of chronic treatment on delay discounting is not well…

Grant, Douglas S. – Learning and Motivation, 2011
Experiments 1 and 2 involved independent groups that received primary reinforcement after a correct match with a probability of 1.0, 0.50 or 0.25. Correct matches that did not produce primary reinforcement produced a conditioned reinforcer. Both experiments revealed little evidence that acquisition or retention was adversely affected by use of…

Lagorio, Carla H.; Hackenberg, Timothy D. – Journal of the Experimental Analysis of Behavior, 2010
Pigeon and human subjects were given repeated choices between variable and adjusting delays to token reinforcement that titrated in relation to a subject's recent choice patterns. Indifference curves were generated under two different procedures: "immediate exchange," in which a token earned during each trial was exchanged immediately for access…

Campos, Heloisa Cursi; Debert, Paula; Barros, Romariz da Silva; McIlvane, William J. – Journal of the Experimental Analysis of Behavior, 2011
A go/no-go procedure with compound stimuli typically establishes emergent behavior that parallels in structure and typical outcome that of conventional tests for symmetric, transitive, and equivalence relations in normally capable adults. The present study employed a go/no-go compound stimulus procedure with pigeons. During training, pecks to…

Yankelevitz, Rachelle L.; Bullock, Christopher E.; Hackenberg, Timothy D. – Journal of the Experimental Analysis of Behavior, 2008
Four pigeons were exposed to a token-reinforcement procedure with stimulus lights serving as tokens. Responses on one key (the token-production key) produced tokens that could be exchanged for food during an exchange period. Exchange periods could be produced by satisfying a ratio requirement on a second key (the exchange-production key). The…

Young, Michael E.; Beckmann, Joshua S.; Wasserman, Edward A. – Journal of the Experimental Analysis of Behavior, 2006
We trained four pigeons to discriminate a Michotte launching animation from three other animations using a go/no-go task. The pigeons received food for pecking at one of the animations, but not for pecking at the others. The four animations featured two types of interactions among objects: causal (direct launching) and noncausal (delayed, distal,…

Sanabria, Federico; Thrailkill, Eric – Journal of the Experimental Analysis of Behavior, 2009
The game of Matching Pennies (MP), a simplified version of the more popular Rock, Papers, Scissors, schematically represents competitions between organisms with incentives to predict each other's behavior. Optimal performance in iterated MP competitions involves the production of random choice patterns and the detection of nonrandomness in the…

da Silva, Stephanie P.; Lattal, Kennon A. – Journal of the Experimental Analysis of Behavior, 2010
The effects of reinforcer magnitude and response requirement on pigeons' say choices in an experimental homologue of human say-do correspondence were assessed in two experiments. The procedure was similar to a conditional discrimination procedure except the pigeons chose both a sample stimulus (the say component) and a comparison stimulus that…

Machado, Armando; Rodrigues, Paulo – Journal of the Experimental Analysis of Behavior, 2007
Two experiments examined how pigeons differentiate response patterns along the dimension of number. In Experiment 1, 5 pigeons received food after pecking the left key at least N times and then switching to the right key (Mechner's Fixed Consecutive Number schedule). Parameter N varied across conditions from 4 to 32. Results showed that run length…

Vasconcelos, Marco; Urcuioli, Peter J.; Lionello-DeNolf, Karen M. – Journal of the Experimental Analysis of Behavior, 2007
We report six unsuccessful attempts to replicate the "work ethic" phenomenon reported by Clement, Feltus, Kaiser, and Zentall (2000). In Experiments 1-5, pigeons learned two simultaneous discriminations in which the S+ and S- stimuli were obtained by pecking an initial stimulus once or multiple (20 or 40) times. Subsequent preference tests between…

DeFulio, Anthony; Hackenberg, Timothy D. – Journal of the Experimental Analysis of Behavior, 2007
Two experiments examined pigeons' postponement of a signaled extinction period, or timeout (TO), from an ongoing schedule of response-dependent food delivery. A concurrent-operant procedure was used in which responses on one (food) key produced food according to a variable-interval schedule and responses on a second (postponement) key delayed the…
