A class of plasticizing chemicals used to make products more pliable or to make fragrances stick to skin. Phthalates disrupt the endocrine system and may cause birth defects. They have been linked to damage of the kidneys, lungs, and liver, as well.
Psychologists have debated the age of adultsâ earliest memories. To date, estimates have ranged from 2 to 6â8 years of age. Some research show that the offset of childhood amnesia (earliest age of recall) is 2 years of age for hospitalization and sibling birth and 3 years of age for a death or change in houses.
Then, around age 3, children's memory capabilities rapidly accelerate to adult levels. However, psychologists have discovered that children as young as 3 months old and 6 months old can form long-term memories. The difference comes in which memories stick around. For instance, it appears that babies are born with more intact implicit, or unconscious, memories.
