1. In an experiment studying the effects of sleep on memory, the independent variable is the factor that is manipulated or changed by the researcher. Here, the amount of sleep participants receive can be controlled by the researcher to observe its impact on memory test - scores. The other options are either dependent variables (memory test scores) or extraneous variables (environment, previous sleep habits).

When adolescents start thinking more logically about abstract ideas and enjoy debating different points of view, this growth is related to their mental processes of thinking, reasoning, and understanding. This falls under the cognitive developmental domain. Emotional development is related to feelings, physical development to bodily changes, and psychosocial development to social and emotional - social interactions.
