AAAS Science and Technology Policy Yearbook 2001
This edition of the AAAS Science and Technology Policy Yearbook
coincides with both the start of the new millennium and the 25th
Anniversary of the AAAS Colloquium on Science and Technology
Policy. In recognition of these events, it takes both a retrospective and prospective look at S&T policy, and examines the mutual impacts of technology and society.
Poverty and the Brain
Tough also deftly summarizes much of the recent work done on the cognitive neuroscience of poverty, or how our brain is changed by the details of our upbringing. (One crucial finding is that "middle-class" parents are much more verbose than parents living in poverty. For instance, one study found that wealthier parents directed an average of 487 "utterances" towards to their child per hour. In contrast, homes with a parent on welfare averaged a mere 178 utterances per hour. This leads, over time, to dramatic differences in the vocabulary size of the child, which strongly correlates with IQ.). (The Frontal Cortex)
