APA Code 1953
-American Psychologists Association wanted to write ethics for psychology -two additional elements: deception and confidentiality -some researchers started putting benefit over risk like milgram and zombardo (1) confidentiality (2) informed consent (3) right to withdraw (4) deception (5) risk vs. benefit
Confidentiality
-Beneficence -it is the researcher's responsibility to protect the participants identity and right to privacy (including participant responses) during and after the research study
Risk-benefit analysis
-Beneficence -weighing the risks against the benefits of a research study to ensure that the benefits outweigh the risks
Beneficience
-Beneficence refers to the reduction of risk of harm to the participants as compared with the benefit of the study. -In other words, a risk-benefit analysis should be conducted to ensure that the benefits of a study outweigh the risks to the participants.
Non Experimental
IV to DV
counterbalencing
a control used in within-subjects experiments where different participants are assigned in equal numbers to the different orders of the conditions
(IV) group differences: experimenter bias
a source of bias in a study created when a researcher treats groups differently based on knowledge
(EV) Demand characteristics
a source of bias that can occur in a study due to participants changing their behavior based on their perception of the study and its purpose
(EV) Hawthorne effect
a source of bias that can occur in a study due to participants changing their behavior because they are aware that they are being observed
a quasi-independent variable is the same as
a subject variable
Independent experimental variable: amount
a variable that includes levels with a different amount of the treatment changing from level to level
Independent experimental variable: type
a variable that involves a manipulation of types of a treatment
Independent experimental variable: presence/absence
a variable that involves a manipulation with a level that involves the treatment and a level that does not involve the treatment
adherence to ethical guidelines in psychological studies with humans is currnently monitored by
an review board at each institution where research is conducted (IRB)

Confederate
apa code: a person who is part of a research study but acts as though he or she is not, to decieve the participant about the study's purpose
Debriefing
apa code: discussing the purpose and benefits of a research study with participants, often done at the end of the study

probability sampling
probability of choosing an individual in the population is known
Double blind design
procedure used to control for experimenter bias by keeping the knowledge of the group assignments from both the participants and the researchers who interact with the participants -double blind eliminates threats to internal validity b/c of random assignment
Single blind design
procedure used to hide the group assignment from the participants in a study to prevent their beliefs about the effectiveness of a treatment from affecting the results
birth weights

respect for persons
the difference in scores tat occurs when we test a sample drawn out of the population is
sampling error
smallest amount of sampling error
simple random
a variable that affects the results of the study but it not a variable of interest is called
confounding variable
Exempt studies
-Exempt studies are those studies that have the smallest amount of risk involved. -They are typically studies that involve educational or cognitive testing of participants, where there is no physical or psychological risk and little or no risk of loss of social standing if confidentiality were to be breached.
Institutional review boards
-a committee of knowledgeable individuals who oversee the ethics of research with human participants conducted at an institution
nominal
-categorical and qualitative -scale of data measurement that involves non-ordered categorical responses -number only means theyre different, numbers used to classify differences -majors, genders -red dresses you're group 1 and blue dresses you're group 2
independent
-cause, predictor -hair length, gender -a variable that in an experiment is manipulated by the researcher such that the levels of the variable change across or within subjects in the experiment
(P) cluster sampling
-clusters of individuals are identified and then a subset of clusters is randomly chosen to sample from -randomly choose doctors and then sample the hospitals they work at
ordinal
-differences put in an order 1. tall 2. second tallest -doesn't tell you how far behind the 6ft and 3 ft person is -scale of data measurement that involves ordered categorical responses
dependent
-effect, outcome -intelligence levels, or friendliness of a child -what you measure -response -a variable that is measured or observed from an individual
Justice
-fair selection of participants -Researchers are responsible for ensuring that all participants have a fair chance of receiving potentially beneficial treatments in research (e.g., treatments for specific mental illnesses or conditions), as well as ensuring that potentially harmful conditions are not exclusively administered to a specific group. -Special considerations must be provided for groups that may be easier to manipulate (e.g., individuals with illnesses, low-income individuals).
Informed consent
-informing participants about the study and then gaining their consent for participation -a form provided to the participants at the beginning of a research study to obtain their consent for the study and explain the study's purpose and risks, and the participants rights as participants
Belmont Report
-lists the responsibilites of researchers as they conduct research with human participants and the rights of those participants before, during, and after a study -provides set of ethical guidelines that researchers must adhere to 1. respect for persons 2. beneficence 3. justice
(P) stratified sampling
-members of a population are selected such that the proportion of a group in the sample is equal to the proportion of that group in the population using random sampling -divide population into groups (maybe republican, and democrat) and then from that you random sample m and f
(NP) Quota sampling
-members of population are selected such that the proportion of a group in the sample -get better understanding
expedited studies
-minimal risk -reviewed by only one member -mau involve a small amount of physical or psychological risk
(P) simple random sampling
-picked out of a hat -most representative, and highest level of EV -sample is chosen randomly from the population such that each individual has an equal chance at being selected -students are chosen randomly from a list
Nuremberg Code
-set of ethical guidelines developed for research with human participants based on information gained during the Nuremburg trials after WW2 -developed by officials involved in the trials as a result of what they learned -early attempt to specify ethical standards for any research involving human participants 1. participation is voluntary, they must be aware of risks 2. must contribute to scientific knowledge and be conducted by qualified researchers 3. avoid harm and terminate if so 4. participants canleave when they want -address important questions - risk weighed against benefit -qualified scientists
full review studies
-studies requiring full review by the IRB so each memeber reviews proposal -special population has a risk of harm, such as studies with particular risk to kids who may not be capable of giving consent
Respect for persons
-treatment of participants in research studies -informed consent
Coercion

involves choosing individuals from the population such that individuals are chosen from a preexisting group
cluster
psychologist developed a test to measure intelligence but this test was poorly developed and really only measured how well people perform on standardized tests in other wordsm it doesnt actually meausre intelligence so it lasks:
construct validity
according to ethical guidelines at the end of their participation participants are often be fully informed as to the purpose of the study and given an explanation of any deception used in the study. is called:
debriefing
External validity
degree to which the results of the study apply to individuals and realistic behaviors outside the study
(IV) group differences: order effects
different order of treatments of a different group but still is a threat to the IV -makes groups unequal
Within subjects variables

include an informed consent process
operational defintion (chp 3)
the definition of an abstract concept used by a researcher to measure or manipulate the concept in a research study
Internal validity
