Childhood adversity affects adult brain and body functions
Adversity in early childhood – in the form of anything from poverty to physical abuse – has measurable changes in the function of the brain and body well into adulthood, according to researchers. Growing up in a low socioeconomic (SES) background can impair working memory as an adult and affect the size of different parts of the brain, while abuse can lead to a higher risk of developing cardiovascular disease in later life.
In a series of presentations that will be made on Tuesday at the annual meeting of the Society of Neuroscience in New Orleans, scientists will report on work studying critical periods of development for the brain. Eric Pakulak, at the University of Oregon, found that people who grew up in lower SES homes had greater deficits in working memory, compared with those with higher SES parents, even when he controlled for the participants' education.
Working memory, Pakulak said, was broadly associated with general intelligence. "As a four- or five-year-old, if you have very good attention and regulations skills, it's a foundational skill that would spill over into other areas of cognition – if you're trying to learn your letters, or to read or learning numbers or math or a musical instrument. When you're learning a musical instrument, you're really training attention.".. Read more:
