Experimental Design 2

A small scale preliminary study conducted in order to determine limitations of the design and improve the study prior to carrying out the study on a larger scale.

• Double blind control

• Random allocation

• Pilot study

• Counter-balancing

• Pretest posttest design

A type of external validity that refers to the generalizability of a study's results across time.

• Placebo

• Temporal validity

• Random allocation

• Participant variability

• Ecological validity

A lot of early psychological research was done exclusively with male participants - this research is considered to be

• Placebo

• Pilot study

• Androcentric

• Ethnocentric

• Random allocation

In experimental research, the researcher manipulates the

• Dependent variable

• Single blind control

• Double blind control

• Placebo

• Independent variable

An experiment in which the researchers know who is receiving the treatment and who is receiving the placebo or control condition - but the participants do not. This is a technique for controlling for the placebo effect.

• Dependent variable

• Single blind control

• Double blind control

• Placebo

• Independent variable

How experimenters divide participants into each experimental condition, to reduce any bias in the distribution of participant characteristics.

• Random allocation

• Pretest posttest design

• Counter-balancing

• Single blind control

• Participant variability

In repeated measures designs, this is when some groups have condition A followed by condition B - and some have condition B before condition A. This is done to test for order effects.

• Random allocation

• Pretest posttest design

• Counter-balancing

• Single blind control

• Participant variability

A problem with experiments is that if they are highly controlled and the environment is artificial, the study may have low

• Placebo

• Temporal validity

• Random allocation

• Participant variability

• Ecological validity

A small scale preliminary study conducted in order to determine limitations of the design and improve the study prior to carrying out the study on a larger scale.

• Placebo

• Pilot study

• Pretest posttest design

• Ethnocentric

• Random allocation

Often we see studies that have sampling bias. In that case, we can say that the study has poor

• Temporal validity

• Ecological validity

• Population validity

• Double blind control

• Single blind control
