Tam, Shu K.E. and Robinson, Jasper and Jennings, Dómhnall J. and Bonardi, Charlotte (2014) Dissociations in the effect of delay on object recognition: evidence for an associative model of recognition memory. Journal of Experimental Psychology: Animal Learning

Rats were administered three 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 two familiar objects, one of which had been presented more recently than the other; and, in the object-in-place task, they discriminated among four previousl...

Dorsal hippocampal lesions disrupt Pavlovian delay conditioning and conditioned-response timing

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 followed immediately by food delivery. Dorsal hippocampal lesions impaired Pavlovian conditioning in this task. They also produced a deficit in interva...

Tam, Shu K.E. and Bonardi, Charlotte and Robinson, Jasper (2015) Relative recency influences object-in-

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 context x or context y. Usually more exploration is seen of the object that has not previously been paired with the test context, an effect attributed to...

Mondragón, Esther and Gray, Jonathan and Alonso, Eduardo and Bonardi, Charlotte and Jennings, Dómhnall J. (2014) SSCC TD: a serial and simultaneous configural-cue compound stimuli

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 cues. This Simultaneous and Serial Configural-cue Compound Stimuli Temporal Difference model (SSCC TD) can model both simultaneous and serial stimulus...
