Psychology paper 2: Research Methods confounding variables - correct answersUncontrolled variables that are actually influencing the DV and contaminating the results demand characteristics - correct answersparticipants guess the aim of the study and form an idea of its purpose and try to respond to the researcher in a way that pleases them (behaviour they want to see) or in a way that displeases them (behaviour they don't want to see) Dependent Variable - correct answersThe variable that the researcher measures, it will be affected by the changes in the IV Extraneous variables - correct answersany variable other than the IV that may affect the DV and are considered beforehand, they need to be controlled so they don't contaminate the results Field Experiment - correct answersConducted in the natural environment with less control over extraneous variables. Researcher manipulates IV deliberately to investigate effect on DV. Independent group design - correct answersEach participant only takes part in one condition of the study. The groups will be exposed to different kinds of treatments. Independent Variable - correct answersThe variable that is directly manipulated by the researcher to see what effect it has on the DV. Lab Experiment - correct answersConducted in an artificial setting with an artificial task and high/ strict control over extraneous variables. Researcher deliberately manipulates IV to see the effect on the DV Matched pairs design - correct answersParticipants are matched in pairs beforehand based on important variables that are relevant to the experiment. Then both members of the pair are randomly allocated to the different conditions of the study Natural experiment - correct answersCan be conducted in a lab or field setting. The IV isn't manipulated by the researcher as it occurs naturally but they still look fo
