PSY 337 - Chapter 2

Behaviorists attributed all learning to:

• Mental maps

• Cognitive schemata

• Learning S-R chains

• Skill acquisition

Which of the following is an example of topography?

• Tracing a sketch

• Making fewer errors

• Reducing learning latency

• Improving final accuracy

If I require a rat to press a lever at 5 grams of force versus 25 grams of force, it is a difference in:

• Strength

• Rate

• Speed

• Intensity

If you are able to speak 25 words per minute correctly in a foreign language, that would reflect a measure of:

• Topography

• Fluency

• Intensity

• Error reduction

The key to an experimental study is that:

• A variable is manipulated

• A variable is measured

• More than 5 variables are measured

• More than 5 variables are manipulated

I give half my rats an experimental drug, and the other half nothing. I record food consumption. Which is true?

• The independent variable is the amount of food they eat

• The independent variable is whether they receive the weight-loss drug

• The independent variable is how much weight they lose

• The study does not have an independent variable

I give all rats an experimental drug, but vary the dosage (some receive 5mg and others get 25mg). This represents:

• Between-participants design

• Correlational design

• Split-level design

• Within-participants design

If I give rats either a strong dose of medicine or no medicine at all, this is an example of a:

• Within-participants design

• Split-level design

• Between-participants design

• Correlational design

Internal validity reflects:

• How well a study applies to the real world

• How well a study appeals to the mass public

• How well a study replicates in other laboratories

• How well a study measures what it intended to measure

If I conducted a well-designed study but it only applies to a specific type of rat, then:

• My study has low internal validity, and low external validity

• My study has high internal validity, and low external validity

• My study has high internal validity, and high external validity

• My study has low internal validity, and high external validity
