J Exp Psychol Anim Learn Cogn
. 2022 Oct;
48(4):370-382.
PMID: 36265025
Considerable discussion has concerned the role of context in conditional discrimination learning. Some authors have proposed that contexts might operate hierarchically on CS-US associations, whereas others have proposed that the...

Wasserman E, Castro L
J Exp Psychol Anim Learn Cogn
. 2022 May;
48(4):315-320.
PMID: 35549395
The associative learning theory of Robert Rescorla and Allan Wagner has been duly celebrated for its 50-year reign as the predominant model in learning science. One special recognition is warranted:...

Wasserman E, Castro L
Curr Dir Psychol Sci
. 2022 Mar;
30(6):495-502.
PMID: 35261490
Appreciating that varied stimuli belong to different categories requires that attention be differentially allocated to relevant and irrelevant features of those stimuli. Such selective attention ought to be definable and...

J Exp Psychol Anim Learn Cogn
. 2021 Oct;
47(3):371-383.
PMID: 34618535
Adaptively and flexibly modifying one's behavior depending on the current demands of the situation is a hallmark of executive function. Here, we examined whether pigeons could flexibly shift their attention...

Castro L, Yang S, Savic O, Sloutsky V, Wasserman E
Psychon Bull Rev
. 2021 Apr;
28(4):1344-1353.
PMID: 33829406
Learning of exceptions - those items that violate a known regularity - takes longer than learning of rule-following items. Studies reporting this disparity have used exceptions that share most of...

Cognition
. 2020 Jul;
204:104350.
PMID: 32634739
Attention to relevant stimulus features in a categorization task helps to optimize performance. However, the relationship between attention and categorization is not fully understood. For example, even when human adults...

Sheridan C, Castro L, Fonseca S, Wasserman E
Learn Behav
. 2019 Feb;
47(3):234-244.
PMID: 30719680
Prior categorization studies have shown that pigeons reliably track features that are relevant to category discrimination. In these studies, category exemplars contained two relevant and two irrelevant features; therefore, category...

Darby K, Castro L, Wasserman E, Sloutsky V
Cognition
. 2018 Apr;
177:30-40.
PMID: 29627718
This work examines cognitive flexibility using a comparative approach. Pigeons (Experiment 1), human children (Experiment 2a), and human adults (Experiment 2b) performed a task that required changing responses to the...

Kim J, Castro L, Wasserman E, Freeman J
Hippocampus
. 2018 Feb;
28(6):392-405.
PMID: 29473984
The hippocampus may play a role in categorization because of the need to differentiate stimulus categories (pattern separation) and to recognize category membership of stimuli from partial information (pattern completion)....

Castro L, Wasserman E, Lauffer M
Cognition
. 2018 Jan;
173:28-33.
PMID: 29289794
Supervised learning results from explicit corrective feedback, whereas unsupervised learning results from statistical co-occurrence. In an initial training phase, we gave pigeons an unsupervised learning task to see if mere...
