Developmental Psychology: ways people change and stay the same from conception to deathII. What is a scientific study?A. Scientific Studies are processes used to obtain and demonstrate discoveries usingscientific research methods for variably sized testing groups Evidence is required, and must be related to what is being tested. Nothing is random, aside from the samples chosen to test in statistical studies. Studies are rigorous – details are important…which makes them a little more difficult to get Searches for Cause-and-Effect Relationships Evidence found overpowers all myths and tall tales- Ex: In relevance to pregnancy, there is a myth stating that boys while in the mother’s womb will ‘ride high’, whereas the girls tend to hang low (regarding where the bulge sits). A scientific study would test this myth using a representative sample of pregnant women and measure bulge against a sonogram reading.III. How Do We Change?A. Physical Changes: changes that can be externally observed.  Examples: weight, height, form, and etceteraThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.B. Cognitive Changes: changes in mental abilities, awareness, perception, judgment, reasoning, and learningC. Psychosocial Changes: generally subtle changes that involve the perception and relationship to ourselves, the people around us, and the worldD. Qualitative Changes: subtle changes in characterization and structure that are quantifiably immeasurable; qualitative changes vary from person to person – very human topics Example: Love and MaturationE. Quantitative Changes: Observable and measurable changes, including, but not limited to, size, shape, and number.IV. What Stays the Same?A. Physical Appearance: A person’s physical appearance changes so slowly, that even after a number of decades, his/her face will generally look the same as it did before.B. Personality: Personalities do not change quickly or completely. However, when pieces of a person’s personality change, it is much easier for it to lean towards the negative side of the spectrum. Example: Paranoia, Pessimism, DepressionC. A change in the positive direction takes far longerV. Conception to DeathA. Development occurs from the moment of conception, even if the life is not capable of livingB. While life may end, a legacy can continue on Legacies and reputations that are left can change even after the person is deceased- Examples:o Van Gogh – the legendary artist committed suicide because he was a failure as an artist; now he is one of the most revered artists of all timeo Nobel – invented gun powder while alive; ironically won the Nobel Peace Prize after deatho Ty Cobb – well respected and famous baseball player whileliving; is now seen as a barbaric, racist, dirty
