Question | Answer |
---|---|
What is a human genome? | The complete set of genetic "instructions" for human reproduction |
What are genes? | Small DNA which synthesize proteins. |
What is a monozygotic twin? | one egg that has identical twins, with identical DNA |
What is a dizygotic twin? | two eggs (fraternal) that have twins are are different, just like ordinary siblings |
What does poly genetic mean? | Many genes contribute to a single trait or characteristics |
What is the twin studies? | If twins are separated at birth, raised in separate families, traits that are heavily influence by genetics will be similar in twins; traits influence more by environment will not. Twins tend to have simialr personalities |
What is the adoption studies? | The environment influences personality traits. Adopted siblings (unless identical twins) that are raised together are not alike regarding personality. |
What is temperament? | personality "temperature" How reactive someone is, short temper or not. |
What is heritability? | The extent to which differences between individuals can be attributed to differing genes. |
What is behavior geneticists? | study how environment and genes interplay to make us who we are |
What is molecular behavior geneticists? | studying how the molecular function and structure of genes influence behavior. |
What are epigenetics? | How environmental factors influence genetic expression. "switched" on/off by environmental influences. |
What are epigenetic marks? | organic molecules that attach themselves to DNA and can block or allow gene expression. |
What do evolutionary psychologists study? | how ware similar and the evolutionary forces that caused those similarities. |
Explain theory of evolution and natural selection. | traits which increase the chances of survival are more likely to be passed on to offspring. |
What is sexual over perception bias? | men typically have more sexual interest in women, and often mistakenly perceive friendliness for sexual interest. |
Explain attachment theory example | Having a child-parent bond in the same room, introduced to toys, and the infant is more likely to play with toys in parent is in room/playing with the toys. If a stranger joins, baby cry, but is fine when parent is not alarmed. |
What are social scripts | Cultural rules for behaving |
What is an enriched environment? | environment with plenty of stimuli and opportunities for interaction and learning. |
what does an enriched environment encourage? | neurological development, not only during infancy, but years down the road. early development sets foundation for brain development for years to come. |
True/False: Parents should take full responsibility for their child's successes and failures | False, the influences from people around them (friends) are usually much stronger, therefore parents should take less credit for their child's successes and less blame for their child's failures. |
Explain the selection effect | The tendency for peers to choose friends that most closely resemble them. |
What is culture | stable shared set of attitudes, behaviors, values, traditions, ideas and norms (socially acceptable) |
What is a collectivist? | cultures that tend to vlaue the success of the cultureal group over individual success and individual identity is highly tied to group. |
What is a individualist? | Cultures that tend to value individual success and emphasize the importance of uniqueness and self above group. |
What is androgyny | A blurring of the line between what is "male" and "female". An androgynous individual may express a mixture of male and female characteristics |
