| Question | Answer |
|---|---|
| Lab experiment: | an experiment done under highly controlled conditions. |
| Field experiment | an experiment done in a natural setting. There is less control over variables. |
| A true experiment | An IV is manipulated and a DV measured under controlled conditions. Participants are randomly allocated to conditions. |
| A quasi experiment: No IV is manipulated and participants are not randomly allocated to conditions. Instead, it is their traits that set them apart | a fish seller, a hot dog vendor and a jeweler. |
| A natural experiment | An experiment that is the result of a "naturally occurring event." For example: Did stress increase at our school after the introduction of the IB? Or did aggression increase in rural Canada after the introduction of television? |
| Independent variable | the variable that is manipulated by the researcher. |
| Dependent variable | the variable that is measured by the researcher. It is assumed that this variable changes as a result of the manipulation of the independent variable. |
| Controlled variables | variables that are kept constant in order to avoid influencing the relationship between the IV and the DV. |
| Standardized procedure | the idea that directions given to participants during an experiment are exactly the same. This is the most basic form of "control" for a study. |
| Random allocation to conditions | In a true experiment, participants are randomly allocated to conditions in order to avoid sampling bias. |
| Aim | purpose of a study |
| Population | a group of people studied |
| Procedure | process by which the researcher will carry out the study |
| Results | numerical or descriptive data that is obtained and processed. |
| Findings | how the researcher interpreted the data |
| Participants | people who take part in a psychological study |
| Target Population | a specific group of people whom are interested in the study |
| Sample | group of people chosen from the target population |
| Representative sample | a sample that represents a population |
| Population validity | the population can be indicative of a larger population |
| Opportunity sampling | a group that already exists |
| Haphazard sampling | a method that is neither random nor systematic |
| Self | selected sample |
| Snowball sampling | participants recruit other participants for a study |
| Random sampling | participants have an equal chance of being selected |
| Stratified sampling | participants match the make |
| Sampling bias | preference of some participants over others |
| Participant variables | differing characteristics of participants |
| Method triangulation | studying behavior by both quantitative and qualitative methods |
| Naturalistic | research conducted in environments in which the behavior is most likely to take place |
| Participant observation | researchers immerse themselves in a setting to observe behavior |
| Overt observation | requires the researcher to gain the trust of the group being observed |
| Covert observation | researcher does not disclose intentions to the groups |
| Cognitive dissonance theory | humans change their beliefs to reduce their feelings of dissonance (inconsistency) |
| Ethics | correct rules when carrying out research |
| Protection from undue stress or harm | participants should not be harmed |
| Informed consent | participants are informed of the study and agree to participate |
| Deception | may be used in a study or an experiment but must be justified |
| Right to withdraw | participants can withdraw at any time |
| Debriefing | true aims and purpose of study is revealed to participants |
| Anonymized | participants identity are anonymous |
