Studies have shown that forgetting is more laborful than remembering

U.S. researchers have discovered using neuroimaging techniques that forgetting something can take more brainpower than remembering it.
researchers at the University of Texas at Austin said in a new issue of the Journal of Neuroscience that they showed a group of healthy adults a series of pictures of scenes and faces, instructing them to remember or forget each image and tracking their brain activity patterns through neuroimaging techniques.
previous studies on "intentional forgetting" have focused on "hot zone" activity in the brain-controlled areas such as the pre-cortical cortical layer and long-term memory regions such as the hippocupal body. The latest study focused on the sensation and perception regions of the brain, especially the abdominal cortical cortical layer, and focused on the analysis of brain activity patterns that correspond to complex visual stimulation memory characteristics.
study found that forgetting an unpleasant experience requires more concentration than remembering it. The results not only confirm the ability of humans to choose what to forget, but also suggest that intentionally forgetting something requires "moderate" activity in the sensory and sensory regions of the brain, which is higher than remembering the same thing.
researchers point out that "moderate" brain activity is essential for "intentional forgetting." Too much brain activity enhances memory, and too weak to change it. Specifically, the subjective intent to forget first increases brain memory activity, which occurs when it reaches a "moderate" level.
"We may want to discard memories that cause adverse reactions, such as traumatic memories, so that we can better face new experiences," said Jarrod Lewis-Picock, an assistant professor of psychology at the University of Texas at Austin who led the study. (Source: Xinhua News Agency)
