The negativity bias also affects memory. Negative experiences are quickly sent to long-term store. By contrast, most positive experiences have little impact on memory systems of the brain unless they are intense or new.
Neuroplasticity refers to the ability of the brain to change through the growth and reorganization of its basic building block, namely neural networks. In other words the brain is malleable. Before the discovery of neuroplasticity, neuroscientists believed that the brain, once fully developed, was static. There was no way to change or further develop it.
