A response rule for positive and negative stimulus interaction in associative learning and performance
The present article presents a response rule developed to account for both positive and negative stimulus interaction. In the response rule proposed...

Potentiation of taste and extract stimuli in conditioned flavor preference learning
In these experiments, we investigated the nature of potentiation in the conditioned flavor preference paradigm. Almond and banana extracts, which...

Temporal integration in Pavlovian appetitive conditioning in rats
We used an appetitive sensory preconditioning procedure to investigate temporal integration in rats in two experiments. In Phase 1, rats were...

Conditioning of tentacle lowering in the snail (Helix aspersa): Acquisition, latent inhibition, overshadowing, second-order conditioning, and sensory preconditioning
In a series of related experiments, we studied associative phenomena in snails ( Helix aspersa ), using the conditioning procedure of tentacle...

CS-duration and partial-reinforcement effects counteract overshadowing in select situations
Two experiments used rats in a conditioned lick suppression preparation to investigate how the conditioned stimulus (CS)-duration and...

Interactions between retroactive-interference and context-mediated treatments that impair Pavlovian conditioned responding
In Pavlovian fear conditioning, context-mediated decrements in conditioned responding (e.g., the US preexposure effect) can counteract competition...

Resistance to Interference of Olfactory Perceptual Learning
Olfactory memory is especially persistent. The current study explored whether this applies to a form of perceptual learning, in which experience of...

Extinction of a saccharin—lithium association: Assessment by consumption and taste reactivity
Extinction of a conditioned palatability shift preceded extinction of conditioned taste avoidance whether rats were tested using a within-subjects...

Trace and long-delay fear conditioning in the develo** rat
In two experiments with rats, we examined the developmental emergence of conditioned freezing following trace and short-delay conditioning and also...

When more is less: Extending training of the blocking association following compound training attenuates the blocking effect
Three conditioned lick suppression experiments with rats were performed to assess the influence, following compound training of two stimuli (A and X)...

Stimulus specificity of concurrent recovery in the rabbit nictitating membrane response
Three experiments demonstrated that, following the extinction of an established conditioned stimulus (CS; e.g., tone), the pairing of an orthogonal...

Surprise and change: Variations in the strength of present and absent cues in causal learning
It is said that “absence makes the heart grow fonder.” But, when and why does an absent event become salient to the heart or to the brain? An absent...

Chemosensory conditioning in molluscs: II. A critical review
We critically review chemosensory conditioning studies with molluscs and find that, in many studies, the influence of nonassociative processes...
-
Interaction of retention interval with CS-preexposure and extinction treatments: Symmetry with respect to primacy
Imposition of a retention interval between cue-outcome pairings and testing can alleviate the retardation of conditioned responding induced by...

The visual search analogue of latent inhibition: Implications for theories of irrelevant stimulus processing in normal and schizophrenic groups
Latent inhibition (LI) is a robust phenomenon that is demonstrated when a previously inconsequential stimulus is less effective in a new learning...
-
Extinction and retraining of simultaneous and successive flavor conditioning
In three experiments, rats received pairings of flavor conditioned stimuli with polycose unconditioned stimuli, in either a simultaneous or a...
-
The role of sensory preconditioning in memory retrieval by preverbal infants
Infants’ memories are highly specific to their training stimuli; they rarely transfer learned responding. In two experiments, we asked whether...

Amygdala and hippocampal activity during acquisition and extinction of human fear conditioning
Previous functional magnetic resonance imaging (fMRI) studies have characterized brain systems involved in conditional response acquisition during...

Chemosensory conditioning in molluscs: I. Failure of contextual conditioning inHermissenda
Aversive chemosensory conditioning alters Hermissenda’s feeding behavior. But opposite behavioral changes have been reported, depending on whether...
