    1. In clinical psychology, treatment decisions are often guided by theories. Consider, for example, dissociative identity disorder (formerly called multiple personality disorder). The prevailing scientific theory of dissociative identity disorder is that people develop multiple personalities (also called alters) because they are familiar with this idea from popular portrayals (e.g., the movie Sybil) and because they are unintentionally encouraged to do so by their clinicians (e.g., by asking to “meet” an alter). This theory implies that rather than encouraging patients to act out multiple personalities, treatment should involve discouraging them from doing this role playing

      I am a bit confused as to why this helps understand prediction.

    2. Men are somewhat more likely than women to seek short-term partners and to value physical attractiveness over material resources in a mate. Women are somewhat more likely than men to seek long-term partners and to value material resources over physical attractiveness in a mate. But why? The standard evolutionary theory holds that because the male investment in becoming a parent is relatively small, men reproduce more successfully by seeking several short-term partners who are young and healthy (which is signaled by physical attractiveness). But because the female investment in becoming a parent is quite large, women reproduce more successfully by seeking a long-term partner who has resources to contribute to raising the child.

    1. In psychology experiments there are numerous other things besides the independent variable that can cause change in the measured dependent variable. In chapter’s two to five we discussed at length how chance and measurement variability (or error) can produce the appearance of differences. We also discussed choices that experimenters can make when designing their experiments to reduce the influence of chance, such as increasing the number of observations, increasing the number of subjects, and improving measurement precision.
