Question 1
The leading cause of deaths in infants between the ages of 1 month and 1 year of age in the United States is:
◦ shaken baby syndrome
◦ protein deficiency
◦ respiratory problems
◦ sudden infant death syndrome
Question 2
The major conclusion to be drawn from Rosenzweig's study of the brains of rats raised in an enriched environment is that:
◦ early experience shapes the way in which the brain develops
◦ genes exert their greatest influence in guiding neural development during the prenatal period
◦ too much "privilege" can cause the development of selfishness that cannot be undone through later training
◦ neural development is for the most part determined by genes, and especially by those carried on the sex chromosomes
