SSCC TD: a serial and simultaneous configural-cue compound stimuli representation for temporal difference learning (2014)
Journal Article

This paper presents a novel representational framework for the Temporal Difference (TD) model of learning, which allows the computation of configural stimuli – cumulative compounds of stimuli that generate perceptual emergents known as configural cue...

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...

The effect of stimulus distribution form on the acquisition and rate of conditioned responding: Implications for theory (2013)
Journal Article

In four experiments rats were conditioned to an auditory conditioned stimulus (conditioned stimulus; CS) that was paired with food, and learning about the CS was compared across two conditions in which the mean duration of the CS was equated. In one,... Read More about The effect of stimulus distribution form on the acquisition and rate of conditioned responding: Implications for theory.

Do personality traits predict individual differences in excitatory and inhibitory learning? (2013)
Journal Article

Conditioned inhibition (CI) is demonstrated in classical conditioning when a stimulus is used to signal the omission of an otherwise expected outcome. This basic learning ability is involved in a wide range of normal behavior – and thus its disruptio...

Dorsal hippocampal involvement in conditioned-response timing and maintenance of temporal information in the absence of the CS (2013)
Journal Article

Involvement of the dorsal hippocampus (DHPC) in conditioned-response timing and maintaining temporal information across time gaps was examined in an appetitive Pavlovian conditioning task, in which rats with sham and DHPC lesions were first condition... Read More about Dorsal hippocampal involvement in conditioned-response timing and maintenance of temporal information in the absence of the CS.

When to hold that thought: an experimental study showing reduced inhibition of pre-trained associations in schizophrenia (2012)
Journal Article

Schizophrenia encompasses a wide variety of cognitive dysfunctions, a number of which can be understood as deficits of inhibition. To date, no research has examined ‘conditioned inhibition’ in schizophrenia - the ability of a stimulus that signals th...

US specificity of occasion setting: hierarchical or configural learning? (2012)
Journal Article

Four experiments in rats examined whether occasion setters and target CSs play qualitatively different roles in occasion-setting discriminations. Two visual occasion setters, A and B, signalled reinforcement of two auditory target CSs, x and y, with... Read More about US specificity of occasion setting: hierarchical or configural learning?.

Dorsal hippocampal involvement in appetitive trace conditioning and interval timing (2012)
Journal Article

Involvement of the dorsal hippocampus (DHPC) in acquisition of Pavlovian trace conditioning and interval timing was examined in an appetitive preparation in which presentations of one conditioned stimulus (CS) were immediately followed by food (delay...

Dorsal hippocampal lesions disrupt Pavlovian delay conditioning and conditioned-response timing (2012)
Journal Article

The involvement of the rat dorsal hippocampus (dhpc) in Pavlovian conditioning and timing of conditioned responding was examined in an appetitive preparation in which presentation of a relatively long, 40-s auditory conditioned stimulus (CS) was foll...

Impaired Pavlovian conditioned inhibition in offenders with personality disorders (2011)
Journal Article

Certain types of violent offending are often accompanied by evidence of personality disorders (PDs), a range of heterogeneous conditions characterised by disinhibited behaviours that are generally described as impulsive. The tasks previously used to... Read More about Impaired Pavlovian conditioned inhibition in offenders with personality disorders.
