Savings and recovery after extinction of a classically conditioned response in the rabbit
… the rate of reacquisition to the original conditioned stimulus (CS) and to a cross-modal CS following various amounts of extinction. In both the rabbit nictitating membrane (NM) preparation and rabbit heart rate (HR) conditioning, there was a graded reduction in the rate of reacquisition as …

Feedback control of cerebellar learning
… by an unconditional stimulus, acquires a conditioned response. Importantly, the conditioned response is timed so that it anticipates the unconditioned response. Available neurophysiological evidence suggests that Purkinje cells, in the cerebellar cortex, generate the conditioned response. …

EFFECTS OF ACUTE THC ADMINISTRATION ON EXTINCTION OF CONDITIONED FEAR RESPONSES IN HUMANS: A FUNCTIONAL ANALYSIS OF HIGH DENSITY EEG
… (THC) administration on extinction of conditioned fear responses. Fear conditioning was initiated using a differential classical conditioning paradigm that paired an aversive unconditioned stimulus (shock) with a signaling stimulus (CS+), whereas another stimulus served as a safety …

Conditioning and retention, as studied in a behavior-genetic analysis of the blowfly Phormia regina: A search for relationships between learning and memory
Using proboscis extension (unconditioned response) to sucrose (unconditioned stimulus), individual blowflies (Phormia regina) were classically conditioned to saline (conditioned stimulus). Directional and stabilizing selection for retention and conditioning, respectively, have bred two strains of …

Operant Conditioning in the King Snake (<em>Lampropeltis getulus getulus</em>)
… study demonstrated that king snakes could be conditioned to press a pigeon key for water reinforcement on a continuous reinforcement schedule. There was evidence of conditioning, extinction, and re-conditioning.</p> <p>Results of this study support the Kleinginna's results (1970)p that …

Aprendizaje inconsciente: Condicionamiento a estímulos visuales subliminales
… visually masked neutral words were used as the conditioned stimuli (CS) and an electric shock as the unconditioned stimulus (US). The inter-stimulus interval (ISI) was established individually. A detection threshold was used in Experiment 1 and an identification threshold in Experiment 2. The …

Comparison of Auditory Thresholds Obtained with a Conditioned and an Unconditioned Response
… sound. One is to observe an animal’s spontaneous response (reflex) to the sound; the other is to train (condition) it to respond to the sound. Because reflexive-response thresholds are typically not as low as conditioned-response thresholds, the question of whether the two thresholds are …

Olfactory conditioned ejaculatory preference in the male rat : implications for the role of learning in sexual partner preferences
… expression, and extinction of a novel conditioned sexual behavior, conditioned ejaculatory preference (CEP), were studied. Male rats allowed to copulate with sexually-receptive females bearing an artificial odor (almond or lemon) displayed a subsequent preference for a female bearing …

Effects of the Administration of 5-Hydroxydl-Tryptophan and 3,4-Dihydroxyphenylalanine on the Acquisition of a Conditioned Avoidance Response
… L-Dopa do not facilitate the acquisition of a conditioned avoidance task. A significant number of inter-trial crossovers was obtained for the L-Dopa group for the 13 days of training and the 5-HTP group for the first 2 days. It was concluded that possible peripheral effects of L-Dopa interfered …

The role of species typical cues in sexual conditioning : analysis of potential adaptive specializations in learning
… of sexual behavior involves the association of a conditioned stimulus (CS) with a live female (the unconditioned stimulus or US). Studies using male domesticated quail have shown that adding taxidermic female head and neck cues to a CS results in facilitated conditioned sexual responding (the …

Effects of priming, food palatability and calorie information on appetite in restrained eaters
… to high calorie information represents a conditioned response to a food that is perceived as palatable and filling. However, responding may be greater for restrained than for unrestrained eaters. Finally, the effect of calorie information on salivation supports the argument against an …

Development of Semantic Reference for Location Symbols by Bottlenose Dolphins (<i>Tursiops truncatus</i>) Using a Two-Way Communication Keyboard
… make associations between a designated cue and conditioned response (Pryor, 1986). Two-way communication, however, in which both species can express wants/needs has been predominantly pursued with apes and dolphins. Studies conducted by Louis Herman demonstrated the capabilities of dolphins to …

The Effects of Progressive Relaxation and Myoelectric Feedback on Respiratory Resistance in Bronchial Asthmatics
… experience. A theory of bronchial asthma as a conditioned response has been recently proposed by several investigators. It was suggested that this conditioned response may be modified by lowering the arousal level, and as a result, decreasing the asthmatic response.</p> <p>The problem …

Insights into drama in the early childhood setting: A rationale for the use of drama
… experience. The expectation was of a less conditioned response both in their conduct and expression within the drama environment. The lessons were captured on video and transcribed, then analysed utilising an ethnomethodological methodology. The responses of these children were recorded in …

The Effects of Manipulating One Requirement of a Conjunctive Schedule on Responding in the Pigeon
… homing pigeons initially trained to peck a red response key on a fixed-interval schedule (FI 180 sec) served as subjects. The inter-reinforcer response range was determined for each subject on the fixed-interval schedule. The ratio values used on the subsequent conjunctive schedules were …
