Document Summary

Experimental: requires exerting control through manipulation & assignment. Manipulation: researcher systematically varies conditions in which ppl do task. Treatments = varying conditions (researcher decides who gets which treatment. No manipulation of iv & some degree of control during data collection. No manipulation in many cases ,", no treatments. Aka correlational research but all research is correlational in seeking relations b/t variables. Hermeneutic approach; attempts to discover reasons for behaviour rather than causes. Observational research: goals = to describe behaviour as it naturally occurs & to assess relationship among variables present. 4 approaches to observation; naturalistic, participant-observer, structured, eld experiments. Naturalistic: some phenomena of interest to science cannot be created in lab (occur naturally) Observer tries to disturb the behaviour of the person being observed as little as possible. Reactivity = subject reacts to presence of observer. Measures: use traces & products physical trace research. Use traces: accretion (collecting litter after public event/handprints on car window) &
