00:00

and here's your schmuck du jour brought to you by yoga the number one [People doing yoga by a lake]

00:07

way to exercise while moving as little as humanly possible yeah all right

00:12

here's your question a researcher is interested in whether or not exercise

00:15

can improve the mood of people diagnosed with depression she decides to teach a [The question being written out]

00:19

yoga class for 10 of her patients diagnosed with depression and will then

00:24

compare their moods to 10 members in her usual yoga class the knowledge of the

00:29

patient's diagnosis unknowingly influences the behavior of the

00:32

researcher while she teaches the yoga class to her patient the instructor is

00:37

extra kind and patient with the group compared to the way she usually treats

00:41

members of the yoga class which of the following best describes the researchers

00:46

behavior potential answers on your Center find your light and well it's [Pause prompt appears]

00:57

just I'm away alright well start would be double-blind bias a basic blind [People sat looking at the sun rise]

01:01

experiment is the minimum standard for all tests involving test subjects a [Two crowds of blindfolded people, control group and test group]

01:06

blind experiment works a little something like this all of the group's

01:09

being studied that's even the control groups have no idea which group they're [Guy walks past with a magnifying glass]

01:13

part of this prevents any placebo effect from taking place however the researcher

01:18

knows which group is which so the possibility of bias yes they'll exist [The research appears in a lab coat]

01:22

however a double-blind experiment means that even the researcher doesn't know [Another research appears with a blindfold on]

01:27

which group is which so that they can't unintentionally influence the outcome

01:31

well this is a step further than the basic blind experiment and describes

01:36

exactly what didn't happen in a given experiment long story short be as an

01:40

easy no confounding variables describes an extraneous variables that correlates

01:46

in some way with both the dependent and the independent variables if you're [The definition of confounding bias is shown]

01:50

attempting to study the correlation between variables a and B it's probably

01:54

not too productive to bring see into the mix and throw everything off however see [The letter C drops down and forces A and B apart]

01:58

describes a piece of data not a behavior that means it's not our answer all right

02:03

what about demand characteristic Adam and characteristic with

02:07

context of psychology describes that tell that indicates to the participant [Definition of demand characteristics is shown]

02:12

exactly what the researcher is looking for potentially influencing the

02:16

participants behavior while the researchers extra creaminess might be

02:20

seen as a demand characteristic well we're considering your overall behavior [Researcher handing over money to a participant]

02:24

not a specific in so he isn't our answer what about experimenter preference that

02:31

sounds exactly like what's going on here but before we namaste and call it a day [Guy puts his hands together and walks off]

02:35

let's take a closer look experimenter preference is simply a made-up variation

02:40

of the actual answer see experimenter bias the unconscious act of a researcher

02:47

treating experimental groups differently is known as experiment or bias if a

02:52

researcher knows which research subjects are assigned to which group he or she [Research pointing to one of the groups]

02:56

may unconsciously skew the results a certain way by treating the depressed

03:01

group differently from the control the researcher is exhibiting experiment or [The researcher gives a prize ribbon to one of the groups]

03:05

bias now if you'd excuse us we have some yoga to get to have active yeah the [Guy watching yoga on the TV as he is laid on the couch eating]

03:10

burrito is part of yoga don't question
