    Amnesia for Complex Naturalistic Scenes and for Objects Following Fornix Transection in the Rhesus Monkey. by Gaffan, D

    Published 1992
    “…The impairment in object discrimination learning in the present experiment is attributable to an interaction of object discrimination learning with scene discrimination learning, and can be understood as an effect of interference in long-term memory. …”

    Scene-specific memory for objects: a model of episodic memory impairment in monkeys with fornix transection. by Gaffan, D

    Published 1994
    “…The animals learned four types of discrimination problem: (1) object-in-place discrimination learning, in which the correct (rewarded) response was to a particular object that always occupied the same place in a particular unique background, (2) place discrimination learning, in which the correct response was to a particular place in a unique background, with no distinctive object at that place, (3) object discrimination learning in unique backgrounds, in which the correct response was to a particular object that could occupy one or the other of two possible places in a unique background, and (4) object discrimination learning in varying backgrounds, in which the correct response was to a particular object that could appear at any place in any background. …”

    Distinct neural signatures of threat learning in adolescents and adults. by Lau, J, Britton, J, Nelson, E, Angold, A, Ernst, M, Goldwin, M, Grillon, C, Leibenluft, E, Lissek, S, Norcross, M, Shiffrin, N, Pine, D

    Published 2011
    “…In experiment 1, we first demonstrated the capacity of this paradigm to generate threat/safety discrimination learning in both adolescents and adults. Next, in experiment 2, we used this paradigm to compare the behavioral and neural correlates of threat/safety discrimination learning in adolescents and adults using functional MRI. …”

    Towards and understanding of the role of associative learning in risk for mental health problems by Byrom, N

    Published 2012
    “…</p> <p>Associative learning paradigms were used to test ability to learn about combinations of information and neuroticism was observed to be associated with strong non-linear discrimination learning. The tendency to focus on specific details was associated with weak non-linear discrimination learning. …”

    Visual agnosia and Kluver-Bucy syndrome in marmosets (Callithrix jacchus) following ablation of inferotemporal cortex, with additional mnemonic effects of immunotoxic lesions of ch... by Ridley, R, Warner, K, Maclean, C, Gaffan, D, Baker, H

    Published 2001
    “…Inferotemporal ablations in the New World monkey, the common marmoset (Callithrix jacchus), produced a persistent impairment on visual discrimination learning and a florid, but transient, Klüver-Bucy syndrome. …”

    Impairment in object-in-place scene learning after uncinate fascicle section in macaque monkeys. by Browning, P, Gaffan, D

    Published 2008
    “…Three previous experiments have shown that a disconnection of frontal cortex from inferior temporal cortex in monkeys impairs a variety of visual learning tasks but leaves concurrent object discrimination learning intact. In the present experiment, three monkeys were trained on an object-in-place task where concurrent object discrimination learning took place within unique background scenes. …”

    Prefrontal Cortex in Learning to Overcome Generalized Fear by Edward Korzus

    Published 2015-01-01
    “…Recent studies on molecular mechanisms that underlie the role of mPFC in fear discrimination learning are discussed. These studies suggest that prefrontal N-methyl-D-aspartate receptors expressed in excitatory neurons govern fear discrimination learning via a mechanism involving cAMP response element-binding protein-dependent engagement of acetyltransferase.…”

    The anterior cingulate and reward-guided selection of actions. by Hadland, K, Rushworth, M, Gaffan, D, Passingham, R

    Published 2003
    “…They were also taught a visual discrimination learning task. Cingulate lesions significantly impaired selection of responses associated with different rewards but did not interfere with visual discrimination learning or performance. …”

    Learning and transfer of object-reward associations and the role of the perirhinal cortex. by Buckley, M, Gaffan, D

    Published 1998
    “…Perirhinal cortex ablation has previously been shown only to impair new postoperative object discrimination learning with large stimulus set sizes (&gt; or = 40 problems). …”

    Specificity of binaural perceptual learning for amplitude modulated tones: a comparison of two training methods. by Kumpik, D, Ting, J, Campbell, R, Schnupp, J, King, A

    Published 2009
    “…These data show that ILD discrimination learning with SAM tones does generalize to an untrained carrier frequency but does not generalize across the midline. …”

    Discrimination, reversal, and shift learning in Huntington's disease: mechanisms of impaired response selection. by Lawrence, A, Sahakian, B, Rogers, R, Hodge, JR, Robbins, T

    Published 1999
    “…HD patients showed no deficits in CP discrimination learning or reversal. In Experiment 3, the performance of HD patients on a probabilistic discrimination and reversal task was examined. …”
