Excitotoxic lesions of the perirhinal cortex leave intact rats’ gustatory sensory preconditioning (2021)
Journal Article

We report findings from two sensory preconditioning experiments in which rats consumed two flavoured solutions, each with two gustatory components (AX and BY), composed of sweet, bitter, salt, and acid elements. After this pre-exposure, rats were con... Read More about Excitotoxic lesions of the perirhinal cortex leave intact rats’ gustatory sensory preconditioning.

An associative analysis of recognition memory: Relative recency effects in an eye-tracking paradigm (2020)
Journal Article

We report 2 eye-tracking experiments with human variants of 2 rodent recognition memory tasks, relative recency and object-in-place. In Experiment 1 participants were sequentially exposed to 2 images, A then B, presented on a computer display. When s...

A Computational Implementation of a Hebbian Learning Network and its Application to Configural Forms of Acquired Equivalence (2019)
Journal Article

We describe and report the results of computer simulations of the three-layer Hebbian network informally described by Honey, Close, and Lin (2010). Simulations were of four published experimental demonstrations of configural acquired equivalence. Exp...

Ratios and effect size (2017)
Journal Article

Responding to a related pair of measurements is often expressed as a single discrimination ratio. Authors have used various discrimination ratios; yet, little information exists to guide their choice. A second use of ratios is to correct for the infl... Read More about Ratios and effect size.

Familiarity-based stimulus generalization of conditioned suppression (2017)
Journal Article

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... Read More about Familiarity-based stimulus generalization of conditioned suppression.

Can existing associative principles explain occasion setting? Some old ideas and some new data (2016)
Journal Article

Since occasion setting was identified as a type of learning independent of 'simple' associative processes, a great deal of research has explored how occasion setters are established and operate. Initial theories suggested that they exert hierarchical... Read More about Can existing associative principles explain occasion setting? Some old ideas and some new data.

Relative recency influences object-in-context memory (2014)
Journal Article

In two experiments rats received training on an object-in-context (OIC) task, in which they received preexposure to object A in context x, followed by exposure to object B in context y. In a subsequent test both A and B are presented in either contex... Read More about Relative recency influences object-in-context memory.

An associative analysis of object memory (2014)
Journal Article

Different aspects of recognition memory in rodents are commonly assessed using variants of the spontaneous object recognition procedure in which animals explore objects that differ in terms of their novelty, recency, or where they have previously bee...

Dissociations in the effect of delay on object recognition: evidence for an associative model of recognition memory (2014)
Journal Article

Rats were administered 3 versions of an object recognition task: In the spontaneous object recognition task (SOR) animals discriminated between a familiar object and a novel object; in the temporal order task they discriminated between 2 familiar obj...

Improved spontaneous object recognition following spaced preexposure trials: evidence for an associative account of recognition memory (2013)
Journal Article

Rodents' biased exploration of a novel object over a familiar object is taken as an indication of recognition memory. According to a general associative model of memory, the biased exploration is a consequence of reduced processing of the familiar ob...

Indirect object recognition: Evidence for associative processes in recognition memory (2012)
Journal Article

Familiarity-based stimulus generalization of conditioned suppression in rats is dependent on the perirhinal cortex (2010)
Journal Article

We report that bilateral, excitoxic lesions of the perirhinal cortex attenuate rats' familiarity-based stimulus generalization. After surgery, rats were preexposed either to 2 auditory stimuli (A and B) or to only 1 auditory stimulus (B). Following p...

Suppression to visual, auditory, and gustatory stimuli habituates normally in rats with excitotoxic lesions of the perirhinal cortex (2009)
Journal Article

In 3 habituation experiments, rats with excitotoxic lesions of the perirhinal cortex were found to be indistinguishable from control rats. Two of the habituation experiments examined the habituation of suppression of responding on an appetitive, inst...
