Document Summary

Psy3128 lecture 2 themes and issues in aging research. To get around this, we do longitudinal research. These are age effects: some are due to differences between birth cohorts. Experimental vs. correlational research: correlational research: we attempt not to influence any variables, and simply measure the relationship between two things, r is what we measure. The value will tell you how strong the correlation is: experimental research: we manipulate a variable and measure its effect on another variable. Explanations for a correlation: there is a causal link, there is a common cause o(cid:374)e thi(cid:374)gs that"s d(cid:396)i(cid:448)i(cid:374)g (cid:271)oth of the (cid:448)a(cid:396)ia(cid:271)les, the correlation is a sheer coincidence (google: spurious correlations), correlation is not causation. Getting from correlation to causation: e. g. , moking lung cancer, correlation (epidemiological studies, evidence from various sources, dose-response relationship, stopping reduces risk filtered/unfiltered cigarettes tobacco smoke contains carcinogens, animal research. Sheer coincidence: since the 1950s, both the atmospheric co2 level and crime levels have increased sharply.
