106. Answers will vary. In longitudinal research, the same people are observed repeatedly over time, and changes in development, such as gains in height or changes in mental abilities, are recorded. Longitudinal studies have drawbacks. For example, it can be difficult to enlist volunteers to participate in a study that will last a lifetime. Many subjects fall out of touch as the years pass; others die. The researchers must be patient or arrange to enlist future generations of researchers. 107. Answers will vary. Freud theorized three parts of the personality: the id, ego, and superego. The id is present at birth and is unconscious. It represents biological drives and demands instant gratification, as suggested by a baby’s wailing. The ego, or the conscious sense of self, begins to develop when children learn to obtain gratification consciously, without screaming or crying. The ego curbs the appetites of the id and makes plans that are in keeping with social conventions so that a person can find gratification but avoid social disapproval. The superego develops throughout infancy and early childhood. It brings inward the wishes and morals of the child’s caregivers and other members of the community.
