25
Q

It is an effective way of controlling demand characteristics, but it
obviously entails deception.

● If you believe that your research can have internal validity without a
cover story, do not use one.

A

Cover strories

26
Q

● Refers to the situation where the experimenter himself/herself does
something that creates confounding in the experiment.

● This happens when the experimenter behaves differently in various
treatment conditions.

A

Experimenter bias

27
Q

Gestures, tone, facial expression of the experimenter varies
across treatment conditions.

A

Experimenter bias

28
Q

This also occurs when the researcher intentionally or unintentionally
gives the subject a cue to respond in a particular way.

A

Experimenter bias

29
Q

____ also known as the _____ or Self-
Fulfilling Prophecy, this refers to the tendency of positive
expectations to influence performance positively, and negative
expectations to influence performance negatively.

A

Rosenthal effect
Pymaglion effect
Self-fulfilling prohecy

30
Q

Experimenter treats subject differently and gives more attention
to the subjects that seems having difficulty in understanding the
instruction.

A

Experimenter bias

31
Q

If consistency of the experimenter’s behavior seems not enough, it is
best to use _____ the subjects do not know
which treatment they are receiving, and the researcher does not know
either.

A

Double-blind experiment

32
Q

• Not assigning participants to treatment conditions until after we have
finished interacting with them.
● Making sure that the scorer of responses does not know which
treatment each subject received.
● Using standardized testing and scoring procedures.
● Keeping the words and voice in reading instructions consistent.
● Anticipating subjects’ reactions or doing pilot study.

A

Other methods

33
Q

• ____ Only control demand characteristics.

• _____ Control both the demand characteristic and experimenter bias.

A

Single blind
Double blind

34
Q

● If possible, use multiple experimenters and make sure that each runs
about the same number of people in each of the conditions of the
experiment (i.e., balancing)

● It is also best to limit face-to-face interactions and adhere to the
experimental procedures

A

Experimenter

35
Q

• In experiment, we need to ensure that the subjects truly represent the
population of our interest

• Volunteers tend to be more sociable, liberal, and less authoritarian
than non-volunteers (Rosenthal and Rosnow, 1969)

A

Volunteer subjects

36
Q

Friends of the researchers should ___ be selected as their subjects
because they can threaten external validity and they might act
differently during the experiment compared to stranger subjects

A

Not

37
Q

Set of extraneous variables that come about from procedures created
by the environment of the research setting

A

Content variable

38
Q

Include subject recruitment, selection, and assignment procedures

A

Content variable

39
Q

If you are allowed to choose your own participants (e.g., through
convenience sampling), it is always best to gather people you do not
know
● You cannot recruit only those who smile and seem friendly

A
40
Q

Even if you have subjects that are aggressive or intimidating, stick
with ____

A

Random assignment

41
Q

WHEN THE EXPERIMENTER CHANGES THEMSELVES

Experimenters could become more accurate and faster as they read
instructions to subjects
● This can be controlled if you are highly practiced before you run any
subjects

A
42
Q

They could also become less interested or bored as they conduct the
experiment
● This can be solved through _____ to ensure that one
condition does not finish earlier than another, or through ____

A

Random assignment
Limiting face-to-face interactions

43
Q

Keep in mind that there is often a trade-off between internal validity
and external validity

A
44
Q

Controlling extraneous variables increases our ____, but it
reduces our ____ at the same time

A

Internal validity
External validity

45
Q

Nonetheless, do not sacrifice the internal validity for the external

48
Q

If you will use ____ mas maganda na dimo kakilala ang kukunin na subjects (looks, regardless of characteristics)

A

CONVENIENT SAMPLING

A

Friendly

54
Q

Ensure that the procedure is ____ when measuring Dependent variable and introducing independent variable. There should be specific procedure that should be adhere (kailangan sundin) For example; 1 hour lang ang time para i-measure ang DV

A

Standardized

55
Q

We should build ___ before random assignment

A

Rapport

56
Q

A

Double blind experiment

57
Q

Kapag ang experimenter ay may ini-expect positively or negatively sa subject they perform what is expected

A

Rosenthal effect

58
