Attitudes to the use of animals in biomedical research: Effects of stigma and selected research project summaries (2023)
Journal Article
Three groups of participants (largely recruited from the UK) completed a survey to examine attitudes to the use of animals in biomedical research, after reading the lay (N = 182) or technical (N = 201) summary of a research project, or no summary (N...

From safety to frustration: The neural substrates of inhibitory learning in aversive and appetitive conditioning procedures (2023)
Journal Article
Inhibitory associative learning counters the effects of excitatory learning, whether appetitively or aversively motivated. Moreover, the affective responses accompanying the inhibitory associations are of opponent valence to the excitatory conditione...

Strain comparisons in inhibitory discrimination learning and novel object recognition procedures (2021)
Journal Article
Strain differences in visual abilities and exploratory tendencies can confound rats’ performance in cognitive tests of learning and memory. In the present study we compared the performance of albino Wistar and pigmented Lister Hooded rats in appetiti...

Time or place? Dissociation between object-in-place and relative recency in young APPswe/PS1dE9 mice. (2021)
Journal Article
This study tests the predictions of a novel analysis of recognition memory based on a theory of associative learning, according to which recognition comprises two independent underlying processes, one relying on the to-be-recognized item having been...

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...

Timing impairments in early Alzheimer's disease: Evidence from a mouse model (2020)
Journal Article
A key characteristic of Alzheimer's disease (AD) is loss of episodic memory-memory for what happened, where and when; this final aspect-timing-is the focus of the present article. Although timing deficits have been reported in AD patients, few parall... Read More about Timing impairments in early Alzheimer's disease: Evidence from a mouse model.
Under the influence of the environment: children’s responding invigorated and biased by predictive cues (2019)
Journal Article
Cues that signal motivationally significant consequences can elevate responding and bias choice. A task known as Pavlovian-to-instrumental transfer (PIT) has been used to assess the influence of these cues on independently trained responses, and to s...

The effect of conditioned inhibitors and preexposed cues on the outcome-specific Pavlovian-to-instrumental transfer (PIT) effect in humans (2019)
Journal Article
Using a human Pavlovian-to-instrumental transfer (PIT) task, Alarcón and Bonardi showed that the selective elevation of instrumental responding produced by excitatory transfer cues was reduced when these cues were presented with a conditioned inhibit...

Associative mechanisms involved in specific Pavlovian-to-instrumental transfer (PIT) in human learning tasks (2018)
Journal Article
Four experiments compared the effect of forward and backward conditioning procedures on the ability of conditioned stimuli (CSs) to elevate instrumental responding in a Pavlovian-to-instrumental transfer (PIT) task. Two responses were each trained wi... Read More about Associative mechanisms involved in specific Pavlovian-to-instrumental transfer (PIT) in human learning tasks.
The effects of stimulus distribution form during trace conditioning (2018)
Journal Article
Three experiments examined the effect of the distribution form of the trace interval on trace conditioning. In Experiments 1 and 2 two groups of rats were conditioned to a fixed duration CS in a trace interval procedure; rats in Group Fix received a...

Blocking by fixed and variable stimuli: effects of stimulus distribution on blocking (2016)
Journal Article
An experiment with rats compared the ability of fixed and variable duration cues to produce blocking. Rats in Group B (Blocking) were trained that both fixed- (F) and variable- (V) duration cues would be followed by food delivery. In a subsequent tra...

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.
Deficits in object-in-place but not relative recency performance in the APPswe/PS1dE9 mouse model of Alzheimer's disease: implications for object recognition (2016)
Journal Article
Performance was examined on three variants of the spontaneous object recognition (SOR) task, in 5-month old APPswe/PS1dE9 mice and wild-type littermate controls. A deficit was observed in an object-in-place (OIP) task, in which mice are preexposed to...

Learning about the CS during latent inhibition: preexposure enhances temporal control (2016)
Journal Article
In three experiments rats were given nonreinforced preexposure to an auditory stimulus, after which this stimulus and a second, novel cue were paired with food. Lower rates of conditioned responding were observed to the preexposed stimulus across the... Read More about Learning about the CS during latent inhibition: preexposure enhances temporal control.
The effect of conditioned inhibition on the specific Pavlovian-instrumental transfer effect (2016)
Journal Article
Four experiments examined the effect of Pavlovian conditioned inhibition on specific Pavlovian-instrumental transfer (PIT) in human participants. The task comprised an instrumental phase in which two responses (R1, R2) were each paired with one of tw...

The effects of ageing and exercise on recollection and familiarity based memory processes (2015)
Book Chapter
In the UK’s 2011 census there were high proportions of people between 20 and 49 years-old, with each 5-year band containing at least 4 million. Thus between 2022 and 2051 we can expect large numbers of people to enter their 60s, around 2 billion glob...

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...
