Go over DV/IV, hypothesis, operational definition (25 min)

 

DV = dependent variable = thing that you measure

IV = independent variable = thing that you manipulate

 

Hypothesis

 

Theoretical definition = what theoretical construct is being measured or manipulated

Operational definition  = what exactly (in concrete terms) is being measured or manipulated

 

Discuss concepts above abstractly

 

Do Color Stroop Demo

            Make transparency

            Color words with pen.

Make some congruent (name=color)

            and some incongruent (name mismatches color)

            Have students do task twice aloud

                        First time, name ink color of words aloud as fast as they can

                        Second time, read words (ignore ink color)

 

Fill-out design worksheet for this experiment

 

Independent variables (and levels)

            Task: Color name, word reading

            Condition: Congruent, Incongruent, Control

 

Design = 2 x 3 factorial, within subject

 

Dependent variables:

            Reaction time

Errors

 

Then assign Design Worksheet for Blair & Banaji, Experiment 1 only
