B.F. Skinner (1904-1990) is often referred to as the father of operant conditioning, and his work is frequently cited in connection with this topic. His book The Behavior of Organisms,[5] published in 1938, initiated his lifelong study of operant conditioning and its application to human and animal behavior. Following the ideas of Ernst Mach, Skinner rejected Thorndikes reference to unobservable mental states such as satisfaction, building his analysis on observable behavior and its equally observable consequences.[6]. To implement his empirical approach, Skinner invented the operant conditioning chamber, or Skinner Box, in which subjects such as pigeons and rats were isolated and could be exposed to carefully controlled stimuli. Unlike Thorndikes puzzle box, this arrangement allowed the subject to make one or two simple, repeatable responses, and the rate of such responses became Skinners primary behavioral measure.[7] Another invention, the cumulative recorder, produced a graphical ...

As has been reported after lesions of the GC (Balleine and Dickinson, 2000), BLA lesions were found to produce a clear deficit in the sensitivity of instrumental performance to post-training changes in the incentive value of the instrumental outcome. The effect of GC lesions was limited, however, to choice performance assessed in an extinction test, whereas the effect of BLA lesions was observed both in extinction and in a test in which both the valued and devalued rewards were delivered contingent on instrumental performance. As such, although the effects of GC lesions appeared to be limited to the ability of rats to freely recall changes in incentive value, the current data suggest that BLA lesions affect the ability of animals to encode those changes, most likely because of a deficit in encoding the motivational significance associated with sensory features of instrumental outcomes. Thus, although the rats were able to discriminate the performance of lever pressing from chain pulling, both ...

Drug effects on operant behavior are often characterized by their effects on rate of responding, usually expressed as the number of responses per unit of time. The time between two consecutive responses constitutes an interresponse time (IRT), and this measure has been used also to characterize the effects of drugs on operant behavior. IRTs which occur during a session can be classified on a statistical basis as: 1) short-IRT, an IRT(s) of short duratio generated by high-frequency responses; 2) pause, an IRT of long duratio generated by low-frequency responses; and 3) post-reinforcement pause, an IRT which immediately follows reinforcement. This investigation used three schedules of water reinforcement (fixed-ratio 20, fixed-interval 90-seconds and variable-interval 20-seconds) to examine how these IRT classes are influenced by changes in water deprivation conditions or amphetamine administration. Base-line IRT distributions depended upon the schedule of reinforcement. Changes induced by doses ...

Finally to make sure the effects of reinforcement/punishment werent specific to learning an operant task the mice were also tested for place preference. In a place preference test an imaginary line divides the cage in half and only one side of the cage activates illumination.. The results were consistent with the previous findings with operant training; the reinforced dMSN mice learned faster and gave stronger responses as well as proved to be far more resistant during the extinction test. Like with the operant task, punished iMSN mice lost all preference during the extinction trial.. In short, reinforced (dMSN) mice learned faster, showed stronger responses, were more resistant to extinction. The punishment mediated pathway (iMSN) gave weak responses between trials and within trials, it was the behavior was prone to extinction.. If you must choose then choose wisely.. REFERENCES.

Five male Long-Evans rats, maintained at 80% of their free-feeding weight, were trained to bar-press for food reward on a one-minute fixed-interval (FI1) schedule of reinforcement. Once stable FI1 baseline response rates were established, dose-response functions were generated for Chlordiazepoxide HC1 (CDZ). Subsequent treatments with CDZ were followed by 30 min. pulsed microwave radiation (MWR) and FI1 behavioral assessment. Pulsed MWR exposures were in the far zone of an anechoic chamber at an averaged incident power density of 1 mW/sq cm (PRF = 300/sec, 3 usec pulse width). After 2 replications of the combined treatments another CDZ dose-response function was generated. This was followed by 3 more CDZ and MWR replications the first of which was carried out at an averaged incident power density of 1 mW/ sq cm2 Increased rates of response for the CDZ and 1 mW/sq cm MWR treatment were demonstrated relative to initial CDZ dose-response functions in 4 of 5 rats tested. However, the dose-response functions

Aplysia can readily exhibit operant conditioning of their head-waving response when bright light is used as aversive reinforcement (Cook and Carew, 1986). In the first paper of this series (Cook and Carew, 1989a), we showed that the electromyographic (EMG) activity of a discrete band of neck muscles, the lateral columellar muscles (LCMs) of Aplysia is significantly correlated with the component of head-waving (the horizontal component) that is modified during operant conditioning. In the present paper, we asked whether the EMG activity of the LCMs themselves could also be contingently modified, using the same procedures that produce operant conditioning of the behavioral response. Differential EMG from the LCMs was recorded in freely behaving animals with chronically implanted muscle cuff electrodes. Animals receiving aversive reinforcement (bright light) that was contingent upon specific patterns of LCM activity readily learned to alter their differential EMG output. Like operant conditioning ...

In the same paper they compared operant (used by Gary Whitford recently) and direct-observation methodologies (a computer pattern recognition system like I used). The following quote summarizes their comparison: Since EPA is concerned ultimately with how chronic, low-level exposure to toxic substances affects behavior, the relative sensitivity of the direct observation and operant methodologies is extremely important. A significant question is: which of the two methods can detect behavioral changes at lower levels of exposure to a given substance? Research beyond the scope of the original EPA contract would be needed to determine minimum concentrations that can be detected with the two methods. Direct observation, however, is as sensitive as operant procedures and in some cases is significantly more sensitive. At an exposure of 0.11 mg/kg of d-amphetamine, PROBE [pattern recognition of behavioral events] indicated dramatic changes in the location of the primate within the cage during the ...

Marian Breland Bailey played a major role in developing empirically validated and humane animal training methods and in promoting their widespread implementation.[14] Marian was a graduate student under B.F. Skinner. Her first husband Keller Breland also came to study with Skinner and they collaborated with him, training pigeons to guide bombs. The Brelands saw the commercial possibilities of operant training, founding Animal Behavior Enterprises (ABE). In 1955, they opened the I.Q. Zoo as both a training facility and a showcase of trained animals. They were among the first to use trained animals in television commercials, and the first to train dolphins and whales as entertainment, as well as for the navy.[14] Keller died in 1965, and in 1976 Marian married Bob Bailey, who had been director of marine mammal training for the navy. They pioneered the use of the clicker as a conditioned reinforcer for training animals at a distance.[13] ABE went on to train thousands of animals of more than 140 ...

Decision-making is a complex process influenced not only by the drive to maximize cumulative reward but also by proximate influences such as the drive to approach feeders, outcome-related cues, and choice reflex tendencies such as lose-shift and win-stay responses. These influences likely involve interactions among multiple brain circuits with unique information-processing capacities (Daw et al., 2005; Balleine and ODoherty, 2010; Gruber and McDonald, 2012). Here, we have revealed dissociations among regions of the striatum in win-stay, lose-shift, and the suppression of approach to the feeders outside of the normal task sequence (e.g. context). This latter behavior (EFS) was insensitive to reinforcements, but it strongly affected subsequent choice in the task; rats lose-shifted away from the last feeder sampled before the subsequent nose poke, regardless of whether feeder entry was from a choice within the operant task or a consequence of EFS. This is a novel mechanism by which ...
