- 6.1-6.2 In a famous series of experiments conducted by Harry Harlow, infant monkeys were separated from their mothers at birth. The infants were then given two surrogate mothers (a terry-cloth "mother" and a wire "mother"), each of which alternately had a nursing bottle that provided food to the infants. The experimental results showed that in frightening situations the infant monkeysA) were more likely to become aggressive toward the wire mother than toward the Terry-cloth motherB) failed to seek out either of the mothers because of their lack of experiences in seeking contact comfort C) preferred the wire mother, even when the Terry-cloth mother had the nursing bottleD) preferred the Terry-cloth mother, even when the wire mother had the nursing bottleE) would run and cling to whichever mother had the nursing bottle
- 6.1-6.2 Researchers hypothesize that the older a baby is when it begins to crawl, the longer it will take the baby to stop exhibiting earlier rocking behaviors. The researchers go into the infant room of a day care center every day for six weeks. Every time a baby rocks, the researchers record it. They document which babies are already crawlers and at what age each started crawling. What will help the researchers with their investigation?A) sharing the researcher's hypothesis with parents before the study begins B) surveying 100 parents about prenatal careC) their knowledge that babies develop fine motor skills before they develop gross motor skills D) their knowledge that rocking behavior develops before crawling behavior and that rocking behavior eventually goes away once crawling behavior begins E) randomly assigning the babies to crawling versus not-crawling conditions
