Cognitive flexibility reflects both a trait that reliably differs between individuals and a state that can fluctuate moment-to-moment. Whether individuals can undergo persistent changes in cognitive flexibility as a result of reward learning is less understood. Here, we investigated whether reinforcing a periodic shift in an object selection strategy can make an individual more prone to switch ...

It is becoming increasingly apparent that the vast blue expanse of ocean—the last frontier—is not as inexhaustible as it once seemed. While we have yet to fully explore the reaches of the sea, technology has granted humans the ability to harvest its wealth. We can now fi sh anywhere, at any depth, for any species.

Economic integration between North and South Korea occurs through three modalities: traditional arm’s-length trade and investment, processing on commission (POC) trade, and operations within the Kaesong Industrial Complex (KIC). In order, these three modalities are characterized by decreasing exposure of South Korean fi rms to North Korean policy and infrastructure. Th rough a survey of 200 Sou...

Different subregions of nucleus accumbens (NAc) have been implicated in reward seeking, promoting flexible approach responses, suppressing nonrewarded actions, and facilitating shifts between different discrimination strategies. Interestingly, the NAc does not appear to mediate shifting between stimulus-reward associations (i.e., reversal learning) when reinforcement is predictable. How these n...
