Overshadowing by fixed- and variable-duration stimuli (2014)
Journal Article
Bonardi, C., Mondragón, E., Brilot, B., & Jennings, D. J. (2015). Overshadowing by fixed- and variable-duration stimuli. Quarterly Journal of Experimental Psychology, 68(3), https://doi.org/10.1080/17470218.2014.960875

Two experiments investigated the effect of the temporal distribution form of a stimulus on its ability to produce an overshadowing effect. The overshadowing stimuli were either of the same duration on every trial, or of a variable duration drawn from... Read More about Overshadowing by fixed- and variable-duration stimuli.

SSCC TD: a serial and simultaneous configural-cue compound stimuli representation for temporal difference learning (2014)
Journal Article
Mondragón, E., Gray, J., Alonso, E., Bonardi, C., & Jennings, D. J. (2014). SSCC TD: a serial and simultaneous configural-cue compound stimuli representation for temporal difference learning. PLoS ONE, 9(7), Article e102469. https://doi.org/10.1371/journal.pone.0102469

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...

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
Jennings, D. J., Alonso, E., Mondragón, E., Franssen, M., & Bonardi, C. (2013). The effect of stimulus distribution form on the acquisition and rate of conditioned responding: Implications for theory. Journal of Experimental Psychology: Animal Behavior Processes, 39(3), 233-248. https://doi.org/10.1037/a0032151

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
He, Z., Cassaday, H. J., Bonardi, C., & Bibby, P. A. (2013). Do personality traits predict individual differences in excitatory and inhibitory learning?. Frontiers in Psychology, 4(245), https://doi.org/10.3389/fpsyg.2013.00245

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
Tam, S. K., Jennings, D. J., & Bonardi, C. (2013). Dorsal hippocampal involvement in conditioned-response timing and maintenance of temporal information in the absence of the CS. Experimental Brain Research, 227(4), 547--559. doi:10.1007/s00221-013-3530-4

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...

When to hold that thought: an experimental study showing reduced inhibition of pre-trained associations in schizophrenia (2012)
Journal Article
He, Z., Cassaday, H. J., Park, S. B. G., & Bonardi, C. (2012). When to hold that thought: an experimental study showing reduced inhibition of pre-trained associations in schizophrenia. PLoS ONE, 7(7), Article e42175. https://doi.org/10.1371/journal.pone.0042175

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
Bonardi, C., Bartle, C., & Jennings, D. (2012). US specificity of occasion setting: hierarchical or configural learning?. Behavioural Processes, 90(3), https://doi.org/10.1016/j.beproc.2012.03.005

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?.

The tasks previously used to... Read More about Impaired Pavlovian conditioned inhibition in offenders with personality disorders.
