Unformatted text preview: Psychology 1000–crazy Friday 8/31 GET A SCANTRON ************* **On Blackboard there is the required research documents!!!!!!!!!!!!!!!! DO EEEET Types of research 1. Descriptive –Systematic observations (going into environment and observing) * No causation or prediction*- naturalistic observation- going into place where you observe DISCRETELY ^^when people know they are being oberserved they act differently_called Hawthorn effect- Ethnographic research ( Going into other environments to study)-Archival research - observing topic from different times.- Case Study - Intensive examination of one person at a time 2. Correlational Research.----- Enables Prediciton...DOES NOT TALK ABOUT CAUSATION *use correlational reseach when we cannot introduce variable for ethical/logistical reasons* *example. Adolescent drug use—cant really interview them because of legal deniability and such*-Correlation Coefficient---- degree of realationship between two or more variables-Positive - variables change in same direction (ex. Age/height up to point)- Negative- variables change into opp. Directions (ex. Sleep/stress) **range of coefficient ranges from 0 to +/- 1.00 ** as variable changes one degree the other changes one degree CORRELATION DOES NOT EQUAL CAUSATION !! 3. Experimental Research- Causal relationship * need a sample of the population- everyone who could be involved in your research question*-representative sample- accurately reflects characteristics of the population (Half population asian–Half sample must be asian–examp.)-random sample- each participant is equally likely to be part of experiment _convienience samples- whoever is on-hand *MOST POPULAR* Variables Independent variable- IV- manipulated by experimenter. Dependent variables _DV_ shows any effects of the IV People exposed to IV — Experimental Groups* people not exposed to IV- Control Groups* Extraneous Variable- anything other than IV that causes change to the DV - Experimenter bias- accidentally signals to participant how they are supposed to respond ^ to not use experimenter bias the experimenter uses double-blind design _when the experimenter does not know what group he is in *ex. In drug study the experimenter doesnt know if perosn had drug or placebo -Ethnocentrism- same stimulus may mean very different things to people of different cultures Random Variables- to avoid..test a lot of people Participant expectancy effects- participants change behavior because they figure out meaning of experiment and answer accordingly Social Desirability response- PARTICIPANTS LIE TO LOOK BETTER!!!!!! 4. Biological research- Lesions- damaged areas of brain Mid-1800's – one way to determine what a particular area of brain does....
