Document Summary

Functional fixedness in problem solving: ex) duncker"s candle problem. Presented with a box of tacks, a matchbox, and candle. If the tacks were presented in the box, the task completion took longer. If the tacks were presented outside of the box, the task was completed faste. Creative problem solving: insiders vs. outsiders, ex) non-invasive strep throat testing, three variables, expertise: expert vs novice in medicine, search variation: single body of knowledge of several, effort: amount of time put into solution. Field of research that uses genetic methods to investigate individual differences in behavior. How related two people are genetically how similar they are in behavior: twin studies. Monozygotic (identical) twins share 100% of genes. Dizygotic (fraternal) twins share 50% of genes. If monozygotic twins are more similar than dizygotic in a behavior/trait, then that behavior/trait should have a large gene faster enetic behavior/trait, then that behavior/trait should have a large gene component: adoption studies.
