Chapter 4 1. the three stages o prenatal life include a. Zygote- 23 chromosomes, this is the very beginning. b. Germinal Period- this is when the mass of cells is planted in the mother’s womb. Nothing more really happens here. c. Embryonic Period- this is from the 9 th week on. This is when the bones are made, along with the muscles and rest of the mind and body. 2. There are many things that can disrupt prenatal development, they range form alcohol in the body, to just the way the mother moves. Environmental agents that can be harmful to an undeveloped baby are called teratogens. 3. As you get older, like the difference between someone in their mid-forties, your dendrites are much smaller and less complex than those of someone in their seventies. 4. there are three main types of research done to test infants mentally: a. the preference technique- this is when you show a single infant a picture of his mother and father always with his mother on the right, and then play a recording of his mother reading to him. Then all of a sudden, one of the days his mother appears on the left, where does he look? Is his attention still towards the noise, or is it towards the mother’s picture? b. The Habituation technique- this is when you are able to measure how great a baby’s memory is by measuring how long its attention span is. Babies are only really interested in new things, and when you show them something again and again, if they remember, it will no longer hold their attention. c. Using rewards- this is like the rat pushing one of two buttons. If the baby crawls to the picture of his mother, then he will be rewarded with some affection. So if you move the picture of his mother, will he go to the picture of his mother or the other? 5. Memory loss in the elderly- as you get old, you become better at recalling information if you have a second to think of the information you need. While when you are younger, you are better at immediate recall. 6. Cognitive capacities include conservation, assimilation, accommodation, and abstract reasoning. a. Assimilation- the process through which we fit new experiences into our schema. b. The process through which we change or modify existing schemata to accommodate new experiences. 7. People didn’t think that there was much of a difference between children and adults; it was only a difference of them being stupid. 8. Basically what this shows is that people and animals prefer something called comfort contact over nourishment. This could be useful in child behavior, because this could show why children usually prefer soft caring mothers from rough fathers with bottles of food.

9. Strange situation attachment- gradually putting children in stressful situations, and seeing how they react toward their caregiver. There are four types of this attachment, secure, resistant, avoidant, or disorganized. a.
