Final answer:
1. True. Research shows that by age 7, children can make judgments about trustworthiness in facial expressions that match adults. 2. False. The habit of looking at other people's faces develops between the ages of 12 and 18 months. 3. True. Politicians with more competent-looking faces are more likely to win. 4. True. Our facial expressions can reveal our thoughts unintentionally.
Step-by-step explanation:
1. True. According to research by Paul Ekman, by age 7, children can make judgments about a face's trustworthiness that match adults' judgments. This suggests that children develop the ability to assess trustworthiness in facial expressions at a fairly young age.
2. False. The habit of looking at other people's faces actually develops between the ages of 12 and 18 months, as babies become more socially aware and begin to recognize and respond to facial expressions.
3. True. Research has shown that politicians whose faces are rated as looking more competent are more likely to win. This suggests that facial appearance can play a role in electoral success.
4. True. Our facial expressions can unintentionally reveal our thoughts. For example, when we feel angry or happy, our facial muscles can involuntarily show these emotions, even if we are trying to conceal them.
