Familiarity-Based Stimulus Generalization of Conditioned Suppression
We report that stimulus novelty/familiarity is able to modulate stimulus generalization and discuss the theoretical implications of novelty/familiarity coding. Rats in Skinner boxes received clicker → shock pairings before generalization testing to a tone. Before clicker training, different groups of rats received preexposure treatments designed to systematically modulate the clicker and the to...
متن کاملStimulus modality effects on transformations of conditioned enhancement and conditioned suppression in rats.
Unconditioned and conditioned effects of house-light offset and acoustic white noise on barpressing behavior maintained by intermittent food reinforcement were tested in male hooded rats. Presentations of these stimuli prior to their acquiring signal value initially tended to depress and then to enhance barpressing rate, but generally the rate of the on-going barpressing was lower during the li...
متن کاملConditioned and unconditioned stress-induced analgesia: Stimulus preexposure and stimulus change
Aversive events such as electric shock lead to analgesia. There have been differing views with regard to whether the aversive event itself can lead to analgesia as a direct unconditioned reaction, or whether the analgesia is instead a reaction to fear conditioned to cues present during shock or to other associative processes initiated by the aversive event. Maier (1989, 1990) has argued that av...
متن کاملEffects of stimulus preexposure on the generalization of conditioned taste aversions in infant rats.
Generalization of a conditioned taste aversion in infant rats and how this is affected by stimulus preexposure was investigated in a series of experiments. In Experiment 1 generalization of a conditioned aversion between two tastes (sweet and salty) was found, and the effect of tastes preexposure was a reduction in generalization (Experiment 2). However, when these tastes were combined with a c...
متن کاملMorphine-induced suppression of conditioned stimulus intake: effects of stimulus type and insular cortex lesions.
Intake of an unconditionally preferred taste stimulus (e.g., saccharin) is reduced by contingent administration of a drug of abuse (e.g., morphine). We examined the influence of insular cortex (IC) lesions on morphine-induced suppression of an olfactory cue and two taste stimuli with different levels of perceived innate reward value. Two major findings emerged from this study. First, morphine s...
