Author(s): Arseneau-Robar TJ; Teichroeb JA; Macintosh AJJ; Saj TL; Glotfelty E; Lucci S; Sicotte P; Wikberg EC;

Sibling relationships as sources of risk and resilience in the development and maintenance of internalizing and externalizing problems during childhood and adolescence

The Recruitment of a Neuronal Ensemble in the Central Nucleus of the Amygdala During the First Extinction Episode Has Persistent Effects on Extinction Expression

Adaptive behaviour under conflict: deconstructing extinction, reversal, and active avoidance learning.

In complex environments, organisms must respond adaptively to situations despite conflicting information. Under natural (i.e. non-laboratory) circumstances, it is rare that cues or responses are consistently paired with a single outcome. Inconsistent pairings are more common, as are situations where cues and responses are associated with multiple outcomes ...
