RESEARCH METHODS AQA A LEVEL PSYCHOLOGY GLOSSARY ALREADY GRADED A Experimental Method ✔✔a research method using random allocation of participants and the manipulation of variables to determine... cause and effect Variable ✔✔A variable is anything that can vary, i.e. changed or be changed, such as memory, attention, time taken to perform a task, etc. Experimental Method ✔✔a research method using random allocation of participants and the manipulation of variables to determine cause and effect Variable ✔✔A variable is anything that can vary, i.e. changed or be changed, such as memory, attention, time taken to perform a task, etc. Independent Variable ✔✔the factor manipulated by researchers in an investigation Dependent Variable ✔✔the factor measured by researchers in an investigation Operationalism ✔✔the process of defining variables into measurable factors Investigator effects ✔✔a researcher effect where researcher features influence participants results Double blind technique ✔✔A double-blind study is one in which neither the participants nor the experimenters know who is receiving a particular treatment. This procedure is utilized to prevent bias in research results. Double-blind studies are particularly useful for preventing bias due to demand characteristics or the placebo effect. Extraneous variables ✔✔variables other than the IV that might affect the DV Confounding Variables ✔✔uncontrolled extraneous variables that negatively affect results Participant variables ✔✔These extraneous variables are related to individual characteristics of each participant that may impact how he or she responds. These factors can include background differences, mood, anxiety, intelligence, awareness and other characteristics that are unique to each person Situational variable ✔✔features of an environment that affect the degree to which individuals yield to group pressure Demand characteristics ✔✔features of a piece of research which allow the participants to work out its aim and/or hypotheses. Participant may then change their behaviour and so frustrate the aim of the research. Single blind technique ✔✔The Single-Blind research method is a specific research procedure in which the researchers (and those involved in the study) do not tell the participants if they are being given a test treatment or a control treatment. Laboratory experiment ✔✔experiment conducted in a controlled environment allowing the establishment of causality Field experiment ✔✔experiment conducted in a naturalistic environment where the researchers manipulate the independent variable Natural/Quasi Experiment ✔✔experiment conducted i [Show More]
