Lanugo is nearly gone. - Basic spinal cord - heartbeat - lanugo disappears When does the Embryonic period begin? - 2 weeks after conception During which trimester is a heartbeat detectable using utrasound? - first Martha's children participated in a study from the time that they were in preschool until they reached middle school. - longitudinal A researcher is studying a group of Baby Boomers to see whether, as they age, they become increasingly religious. - longitudinal Teenagers in a study are interviewed regarding who are the most popular peers in their grade. - Cross-sectional Why might a researcher decide to use a survey as the research method of choice? Give two reasons. - Obtain large sample Study additional options Efficiency Cost Effective Place the following prenatal stages in order, from earliest to latest: Embryonic, Fetal, Germinal. - germinal - embryonic - fetal What are the advantages and disadvantages of naturalistic observations? Describe one advantage and one disadvantage. - Advantage: observe participants realistically with natural behaviors Disadvantage: Can only observe behaviors, not thoughts. The module discussed three key variables that influence the effect of a teratogen. A) Describe these three variables. B) Then, name an example of a teratogen. C) Finally, come up with a realistic scenario (that is, make up a story) about a mother and child for whom this teratogen might play a role, and describe how the three key variables influence the effect of that specific teratogen in this specific example. - A. Age/ Gestation at which the baby is exposed to the teratogen. If it is at a vital point when the organs are developing the baby is at risk at more harm. The amount of teratogen the baby is exposed to. The more exposure correlations to the more damage to the baby. The susceptibility of a teratogen that is present with the mother may/ may not pass to her child. B. Nictone C. A mother smoking nicotine during her pregnancy. During the stages and gestational phases she smoked may or may not have an effect on the baby. The amount of nicotine she uses may effect the baby. The susceptibility of the mother to nicotine may pass on to the child. The lasting effects on nicotine on the child range from miscarriage, low birth weight, SIDS, development problems, premature birth, learning disabilities.

Smoking during pregnancy can cause a miscarriage. - True What is the current age of viability? - 22-26 weeks During which trimester do hair and nails typically form? - second What are the advantages and disadvantages of conducting an experiment? Give one advantage and one disadvantage. - Advantage: observe directly/ determine causality Disadvantage: human error/ hawthorne effect (subject acting unnaturally) What are the two key features of an experiment that enable it to determine causality? Name these features and then describe them - Manipulation - the experimenter administering something to the participants
