Kenny Yu; Wolf Vanpaemel; Francis Tuerlinckx; Jonas Zaman – npj Science of Learning, 2024
Perception and perceptual memory play crucial roles in fear generalization, yet their dynamic interaction remains understudied. This research (N = 80) explored their relationship through a classical differential conditioning experiment. Results revealed that while fear context perception fluctuates over time with a drift effect, perceptual memory…

Atlas, Lauren Y.; Phelps, Elizabeth A. – Learning & Memory, 2018
Fear-relevant stimuli such as snakes and spiders are thought to capture attention due to evolutionary significance. Classical conditioning experiments indicate that these stimuli accelerate learning, while instructed extinction experiments suggest they may be less responsive to instructions. We manipulated stimulus type during instructed aversive…

Jones, Carolyn E.; Monfils, Marie-H. – Learning & Memory, 2016
Traumatic experiences early in life can contribute to the development of mood and anxiety disorders that manifest during adolescence and young adulthood. In young rats exposed to acute fear or stress, alterations in neural development can lead to enduring behavioral abnormalities. Here, we used a modified extinction intervention…
