Purpose Psychological studies provide information about what we do, why we do it and what changes take place in the process.

What is a sample??? `

METHODS OF RESEARCH List the 4 methods of research in you notebook. 1. NO 2. CS 3. LS 4. S

What are the 3 types of studies? 1. C 2. C 3. E

Lets Get Started.. Decide what you want to know about Then….

FORUMLATE A HYPOTHESIS A CLEARLY DEFINED STATEMENT OF EXPECTED RESULTS. EDUCATED GUESS…

TEST HYPOTHESIS Determine the best method to use to test your hypothesis and then develop your procedures. Determine if you need an experimental group and one or more control groups.

EXPERIMENTAL METHOD You’ll need two different groups.. Experimental group- receives the independent variable Control group- does not receive the independent variable If………..(independent variable) Then……….(dependent variable)

EXAMPLE STRICT PARENTS RAISE CHILDREN WHO RARELY GET IN TROUBLE. Agree / Disagree The independent variable is the “if” part of the experiment The dependent variable is the “then” part of the experiment-what you are measuring.

MY HYPOTHESIS Your hypothesis… parents and how they raise children… WRITE ONE NOW… IF.. THEN..

Placebo Sometime a placebo is used in experiments What's that?? Why?? Attempt to control other variables

Placebo The POWER of SUGGESTION… Hypochondriacs…

EXPERIMENTAL GROUP EXPOSED TO THE ______________ WHAT YOU ARE TESTING

Control Group ______ EXPOSED TO THE INDEPENDENT VARIABLE

SCENERIO AT 3:00 A.M. IN NYC, KITTY GENOVESE WAS ATTACKED ON THE STREET IN FRONT OF HER APARTMENT. IT TOOK THE MAN OVER 30 MINUTES TO MURDER HER.

38 NEIGHBORS STOOD AT THEIR WINDOWS AND WATCHED

Additional info.. KITTY BROKE AWAY FROM HER ASSAILANT, ONLY TO BE CAUGHT AGAIN. SHE SCREAMED FOR HELP OVER AND OVER AGAIN. NO ONE HELPED HER OR CALLED THE POLICE. FINALLY, ONE NEIGHBOR CALLED THE POLICE, BUT IT WAS TOO LATE FOR KITTY.

What is your hypothesis? HYPOTHESIS IS…

PONDER… IN A GAME OF CATCH, THE WAY THE BALL IS THROWN WILL AFFECT WHETHER THE BALL IS CAUGHT. STUDENTS SCORE HIGHER ON ACT TESTS IN THE MORNING THAN IN THE AFTERNOON HYPOTHESIS???

Additional Methods

LABORATORY EXPERIMENT

FIELD EXPERIMENT

SURVEY METHOD

NATURALISTIC OBSERVATION

INTERVIEW

PSYCHOLOGICAL TEST MORE ACCURATE, OBJECTIVE DATA

PSYCHOLOGICAL TEST OFTEN COMBINED WITH THE INTERVIEW PROVIDE SUBJECTIVE AND OBJECTIVE PERSPECTIVE.

CASE STUDY METHOD

LONGITUDINAL METHOD

CROSS-SECTIONAL LESS EXPENSIVE AND TIME- CONSUMING THAN THE LONGITUDINAL METHOD. NOT APPROPRIATE FOR STUDIES ONDEVELOPMENT OVER TIME.

CAN YOU TRUST THOSE POLLS What do you think???

From what you now know about the standards of research studies, find out as much as you can about any study or poll that you read about in a newspaper or magazine.
