Total questions: 14
Worksheet time: 10mins
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
the person who designs an experiment is the:
investigator
experimenter
participant
designer
the narrow definition of an investigator effect is any effect the investigator has on:
an investigation
P's behaviour
EV's
all of the above
ecological validity concerns:
representativeness
generalisability
representativeness and generalisability
representativeness and reliability
if the P's in a study are all only men, the study COULD have low:
population validity
ecological validity
external validity
population validity & external validity
