Developmental Psychology Study Guide 1) Qualitative change is a change in quality or style. This change is not easily counted. For example it would be something like the way a child does something. If one time they hop and they can’t keep their feet together but a few weeks later they can keep their feet together when they hop and land on both feet at the same time, that would be a qualitative change. On the other hand a quantitative change is something that can be counted. For example as a child develops their weight and height fluctuates. For the most part if they are developing correctly their weight and height should increase or stay the same as they get to their peak. 2) Maturation is changes that result from the unfolding of an individual’s genetic plan. An example of maturation would be the natural process of puberty in both girls and boys. This process happens at different times for each person because it depends mainly on the individual’s genetic plan. Learning is permanent changes resulting from interaction with the environment. For example if a child learns and observes people fighting all the time such as parents, they are more likely to be aggressive and start fights in school. 3) The cohert effect is belonging to a particular generation, basically being raised in a particular time. When observing people, you must also be aware of the generation in which they grew up in. The environmental factors at that time could most likely have a huge influence on their behavior today. For example the children who grew up during the depression, know the value of a dollar while as most kids today seem to believe that money grows on trees and don’t really know the value of hard work because they are handed everything. 4) The four methods that a researcher can use to collect physiological data are 1. Observation - a researcher might choose this one because you can catch something in a person’s own environment. They can also not now that you are watching and therefore you can get more data. A potential problem though is that if the subject knows the researcher is watching their behavior may change. 2. Surveys – A researcher may chose to do a survey because you are able to get a random sample. You may also be able to get more data because you could have more subjects respond. The problem with a survey is that people can lie so you could receive false data. 3. Case Study - a researcher might chose to do a case study because you are able to observe an individual person for an extended period of time and seeing patterns and such. The limitation with a case study is that you are only getting data from one subject. You don’t know if the person being observed is similar to others with the same condition. 4. Experiment – allow us to find a cause and effect relationship. The researcher is able to manipulate and control the situation as much as possible. The limitation with experiments is that the subjects may hold back information knowing they are under watch. 5) Correlation is a relationship between two variables. A cause and effect relationship is that one
