Q

which of the following describes that exists but is not being directly examined

A

extraneous

31
Q

what aspect of a study is threatened if the participants are tested in one treatment condition at one time and then tested in second treatment condition at a different time

A

internal validty

32
Q

minimizes the potential for experimentor bias

A

single blind and double blind

33
Q

demand characterisitcs

A

any of the potential cues or features of a study that suggests to participants what the purpose and hypothesis is and influence the participant responds or behaves a certain way

34
Q

true experiment

A

must demonstrate that changes in one variable are directly responsible for causing changes in the second variable

35
Q

4 elements of an experiment

A

manipulation
measurment
comparison
control

36
Q

independent variable

A

variable manipulated by the researcher

37
Q

dependent variable

A

variable observed for changes in assess to the effects of manipulating the independent variable

38
Q

levels

A

different values of the indenpendent variable selected to create and define the treatment conditions

39
Q

manipulation

A

consists of identifying the specific values of the independent variable to be examined and then creating a set of treatment conditions to the set of identified values

40
Q

randomization

A

use of a random process to help avoid a systematic relationship between two variables

41
Q

random assignment

A

use of random process to assign participants to treatment conditions

42
Q

which of the following is the primary goal for randomly assigning participants to treatment conditions in an experiment

A
43
Q

experimental condition

A

condition in which the treatment is administered

44
Q

control conditon

A

the condition in which the treatment is not administered

45
Q

no treatment control condition

A

condition in which the participants do not receive the treatment being evaluated

46
Q

placebo

A

fake treatment

47
Q

placebo effect

A

postivie response by a participant to an inert medication that has no real effect on the body

48
Q

placebo control condition

A

condition in which participants recieve a placebo instead of the actual treatment

49
Q

manipulation check

A

is an additional measure to assess how the participants perceived and interpreted the manipulation and or to asses the direct effect of the manipulation

50
Q

types of manipulations

A
  1. participant manipulation
  2. subtle manipulation
  3. placebo control
  4. simulations
51
Q

simulation

A

creation of conditions within an experiment that stimulate or closely duplicate the natural environment in which behaviors being examined normally occur

52
Q

mundane realism

A

refers to supeficial characteristics of the stimulation which may effect internal validity

53
Q

experimental realism

A

extent to which participants become immeresed in the simulation and behave normally and not know they are in an experiment

54
Q

within-subjects- design

A

one group, tested multiple times

55
Q

between subjects

A

2 groups tested on the same data

56
Q

which statement best characteristics a between-subjects experimental design

A

each participant is assigned to one condition of the experiment

57
Q

in a between-subjects experiment, if the participants in one group have characteristics that are different from the participants in another group, which is threatened

A

internal validity

58
Q

matching

A

involves assigning individuals to groups so that a specific participant variable is balanced, or matched, across the groups
-the intent is to create groups that are equivalent with respect to the variable matched

59
Q

limitation of using matching rather than a random assignment to form groups in between subjects

A

matching requires another measurement procedure

60
Q

how does holding a variable constant prevent the variable from becoming a confound

A

it eliminates the possibility that the variable will be substantially different from one group to another

61
Q

variance

A

statistically, value that measures the size of the differences from one score to another

62
Q

differential attribution

A

refers to differences in attribution rates from one group to another and can threaten the internal validity of a between-subjects experiment

63
Q

diffusion

A

the spread of the treatment from the experimental group to the control group which leads to reduce the difference between 2 conditions

Q

compensatory equalization

A

when both groups demand the same treatment

65
Q

resentful demoralization

A

giving up when special treatment is found for other groups

66
Q

compensatory rivalry

A

one group works extra hard to make up for not receiving the benefits received by another group

67
Q

single factor multiple group design

A

testing one thing in 3 different conditions

68
Q

limitation of a two-group design

A

may not provide a complete picture of the relationship between variables
