Experimentation
![Page 2: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/2.jpg)
Bell ringer
Do you think listening to music while you read interferes with reading comprehension? Explain
![Page 3: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/3.jpg)
Lets see how we would conduct an experiment on whether listening to music interferes with reading comprehension. Identify the variables and conditions
![Page 4: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/4.jpg)
Experiment
A scientific method in which researchers manipulate, or change, a variable to observe the effect on some other variable
Proves cause and effect relationship
![Page 5: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/5.jpg)
Independent Variable
The variable that is manipulated or changed.
The variable whose effect is being studied.
The Cause
What is the independent variable in our experiment?

Music
![Page 7: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/7.jpg)
Dependent Variable
The experimental factor that is being measured. The constant
Variable may change in response to manipulations on the independent variable
The Effect
What is the dependent variable?

Reading Comprehension
![Page 9: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/9.jpg)
Confounding variable
Confounding variables (aka third variables) are variables that the researcher failed to control, or eliminate, damaging the validity of the experiment
What is a possible confounding variable?
![Page 10: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/10.jpg)
Volume of music
Level of reading
![Page 11: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/11.jpg)
Experimental Condition (group)
The condition (group) of an experiment that exposes participants to the independent variable
What is the experimental condition?
![Page 12: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/12.jpg)
Listening to music while reading
![Page 13: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/13.jpg)
Control Condition (group)
Contrasts with the experimental condition and serves as a comparison for evaluating the effect of the treatment
The constant or controlled condition
What is the control condition?
![Page 14: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/14.jpg)
Reading without music
![Page 15: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/15.jpg)
Random Assignment
Assigning participants to experimental and control conditions by chance
![Page 16: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/16.jpg)
Placebo
Used in experiments with substances (active agents) such as drugs
Pseudotreatment that is administered instead of the active agent to see if it triggers the same results
Blind experiment: Participants don’t know if they receive the placebo
Think of an example of a placebo
![Page 17: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/17.jpg)
Placebo effect
Effect on behavior caused by a placebo
Thinking you are receiving treatment or a drug will cause people to act a certain way
![Page 18: Experimentation. Bell ringer Do you think listening to music while you read interferes with reading comprehension? Explain.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f355503460f94c52c43/html5/thumbnails/18.jpg)
Double-Blind Procedure
Both the research participants and and the research staff do not know which group has received the placebo
Eliminates bias and enthusiasm
