- belief in β a treatment
- may be enough β to change
- the course β of a personβs
- physical β illness
- mental β illness
IMPURE β PLACEBO
- MEDICATIONS β THAT HAVE
- ACTIVE EFFECT β BODY
- BUT NOT β ON THE
- CONDITION β BEING TREATED
HOW DO β PLACEBOS WORK
- SELF-LIMITING β DISORDERS
- REMISSION
- CHANGE β IN BEHAVIOR
- ALTERED β PERCEPTION
- REDUCED β ANXIETY
- BRAIN β CHEMICALS
- ALTERED β BRAIN STATE
- CHARACTERISTICS β PLACEBO
- THE PERSONβS β ATTITUDE
- DOCTOR-PATIENT β RELATIONSHIP
SELF-LIMITING β DISORDERS
- MANY CONDITIONS β SUCH AS
- COMMON β COLD
- THEY WILL β RESOLVE
- BY THEMSELVES β ANYWAY
- WITH β WITHOUT
- PLACEBOS β MEDICATIONS
- THE END β SYMPTOMS
- JUST A β COINCIDENCE
REMISSION
- SYMPTOMS β SOME DISORDERS
- SUCH AS β MULTIPLE SCLEROSIS
- LUPUS β MAY
- COME β AND GO
- A REMISSION β DURING
- COURSE OF β PLACEBOS
- MAY BE β COINCIDENCE
CHANGE IN BEHAVIOR β PLACEBO
- THE PLACEBO β MAY INCREASE
- PERSONβS β MOTIVATION
- TO TAKE β BETTER CARE
- OF β THEMSELVES
- IMPROVED β DIET
- REGULAR β EXERCISE
- REST
ALTERED PERCEPTION β PLACEBO
- THE PERSONβS β INTERPRETATION
- OF THEIR β SYMPTOMS
- MAY CHANGE β WITH EXPECTATION
- OF FEELING β BETTER
- THEY MAY β INTERPRET
- SHARP PAIN β UNCOMFORTABLE
- TINGLING β INSTEAD
REDUCED ANXIETY β PLACEBO
- TAKING β PLACEBO
- EXPECTING β FEEL BETTER
- MAY BE β SOOTHING
- REDUCE β LEVELS
- STRESS β CHEMICALS
- THE BODY β PRODUCES
- SUCH AS β ADRENALINE
BRAIN CHEMICALS β PLACEBO
- PLACEBOS β MAY TRIGGER
- RELEASED β BODYβS OWN
- NATURAL β PAIN RELIEVERS
- THE BRAIN β CHEMICALS
- KNOWN AS β ENDORPHINS
ALTERED BRAIN STATE β PLACEBO
- RESEARCH β INDICATES
- THE BRAIN β RESPONDS
- AN IMAGINED β SCENE
- IN MUCH β THE SAME WAY
- AS IT RESPONDS β TO
- ACTUAL β VISUALISED SCENE
- PLACEBO β MAY HELP
- BRAIN β REMEMBER
- TIME BEFORE β ONSET
- SYMPTOMS β AND THEN
- BRING β ABOUT
- CHANGE TO β THE BODY
- THIS THEORY β IS CALLED
- REMEMBERED β WELLNESS
PLACEBO β APPEARANCE
- IF THE PILL β LOOKS REAL
- THE PERSON β TAKING IT
- IS MORE β LIKELY
- TO BELIEVE β THAT IT
- CONTAINS β ACTIVE MEDICINE
- RESEARCH β SHOWS
- LARGER SIZED β PILLS
- SUGGEST β STRONGER DOSE
- THAN β SMALLER PILLS
- TAKING β TWO PILLS
- APPEARS TO β BE MORE
- PONTENT β THAN JUST 1
- GENERALLY β INJECTIONS
- MORE POWERFUL β THAN PILLS
THE PERSONβS ATTITUDE β PLACEBO
Incompleto
- IF PERSON β EXPECTS
- TREATMENT β TO WORK
- THE CHANCES β ARE HIGHER
- BUT PLACEBOS β CAN
- STILL WORK β EVEN IF
- PERSON IS β SCEPTICAL
- OF SUCCESS
RELIABILITY
- CONSISTENCY OF β RESULTS
VALIDITY
- EFFECTIVENESS
- IN β MEASURING
- WHAT IT β WAS
- DESIGNED β TO
- MEASURE
What type of experimental design uses each participant as his/her own control?
- A within-subjects β design
- exposes β each participant
- to the β treatment
- and β compares
- their β pre-test
- post-test β results
- This design β can also
- compare β the results
- of two β different
- treatments β administered
How do researchers specifically define what variables mean?
- Researchers β use
- operational β definitions
- to precisely β describe
- variables β in relation
- to β their study
- for β example
- effectiveness β of studying
- can be β operationally defined
- with a β test score
What is a single-blind procedure?
- research β design
- in which β the subjects
- are β unaware
- if they β are in
- control β group
- experimental β group
- demand β characteristics
What is a double-blind procedure?
- research β design
- in which β neither
- the β experimenter
- nor the β subjects
- are β aware
- whoβs β in the
- control β group
- experimental β group
- experimenter β bias
What is the Hawthorne effect?
- individuals β who
- are being β experimented on
- behave β differently
- than in their β everyday life
How are quasi-experiments different from controlled experiments?
- Random β assignment
- is not β possible in
- quasi β experiments
What types of research are considered quasi-experiments?
- Differences in β behavior between
- males β females
- various β age groups
- students in β different classes
Define: correlational research
- establishes β relationship
- between β two variables
- doesnβt β determine
- cause β effect
- used to make β predictions
- and generate β future research
List three types of correlational research
- naturalistic observation
- surveys
- tests
Clinical trials (placebo)
- there are many β clinical trials
- where a person β who has taken
- the placebo β has reported
- an improvement β symptoms
Define naturalistic observation as it relates to correlational research
- consists of β field observation
- of naturally β occurring behavior
- such as β the way
- students β behave
- in the β classroom
- there is β no
- manipulation β of variables
