Reliability and validity MCQ

which of the following is not a characteristic of a field experiment?

• conducted in a natural environment

• IV is directly manipulated by the experimenter

• extraneous variables can be controlled

• P's are often not aware they're being studied

which of the following is NOT a characteristic of a lab experiment?

• conducted in a natural environment

• IV is directly manipulated by the experimenter

• EV's can be well controlled

• P's are often aware they're being studied

mundane realism refers to:

• using a video to capture P's behaviour

• a study being boring & not holding P's interest

• the extent to which the study mirrors the real world

• a Spanish football team

Variables in an experiment are operationalised - meaning:

• understandable to P's

• used in a medical experiment

• described in a way that is easily measured or manipulated

• turned into numbers

lab experiments are sometimes artificial because:

• P's know they are being studied & this may affect their behaviour

• setting may lack mundane realism

• IV may be operationalised in such a way that doesn't represent real-life experiences

• all of the above

internal validity is concerned with:

• generalisability of research

• consistency of measurement

• whether an observed effect can be attributed to the IV

• if the findings are what the experimenter expected

external validity refers to:

• generalisability of findings

• whether findings are what the experimenter expected

• whether an observed effect can be attributed to the IV

• All of the above

which of the following is NOT a kind of external validity?

• ecological

• mundane

• population

• temporal

demand characteristics are:

• uncontrollable features of the study

• threats to external validity

• problem behaviours

• cues in a study that help P's work out the hypothesis

which of the following would not be a threat to internal validity?

• experimenter bias

• P's reactivity

• social desirability bias

• single-blind design
