Volunteer sampling can lead to:

• Less bias

• Low reliability

• Demand characteristics

• Biased sample

Which design involves repeating the same test with the same participants?

• Matched pairs

• Repeated measures

• Independent measures

• Volunteer sampling

In Saavedra & Silverman, what was the phobia?

• Spiders

• Loud noises

• Buttons

• Heights

What is operationalization?

• Making variables measurable

• Applying theory to practice

• Asking volunteers to join

• Repeating the experiment

AO Skill Identification: "This procedure was highly standardized, which supports replication."

• AO1

• AO2

• AO3

AO Skill Identification: "Participants reported their dreams during REM sleep."

• AO1

• AO2

• AO3

A strength of lab experiments is:

• High ecological validity

• Natural behavior

• Control of variables

• Large samples

AO Skill Identification: "A limitation of the study is its low population validity."

• AO1

• AO2

• AO3

AO Skill Identification: "This might not apply to adults, since only children were studied."

• AO1

• AO2

• AO3

What is inter-rater reliability?

• Reliability across different tests

• Agreement between raters

• When DV stays constant

• Ecological consistency
