Encoding and inhibition of arbitrary episodic context with abstract concepts
Davis, Charles P.; Paz-Alonso, Pedro M.; Altmann, Gerry T. M.; Yee, Eiling (SPRINGER, 2022)Context is critical for conceptual processing, but the mechanism underpinning its encoding and reinstantiation during abstract concept processing is unclear. Context may be especially important for abstract concepts—we ... -
Functional characterization of correct and incorrect feature integration
Rodríguez-SanEsteban, Pablo; Chica, Ana B.; Paz-Alonso, Pedro M. (OXFORD, 2023)Our sensory system constantly receives information from the environment and our own body. Despite our impression to the contrary, we remain largely unaware of this information and often cannot report it correctly. Although ... -
