Identify a trend -- use numerical data. Key Science Skills (CH1): 01 Psychology is: The **scientific** study of human behaviour and mental processes. Mental processes are a series of actions that takes place in the mind. Behaviour is any action that someone else can observe and measure. (e.g. Whistling aloud is a behaviour, while thinking about what to have for dinner is a mental process) Aim: A statement that outlines the purpose of an investigation. Hypothesis: A testable prediction of the relationship between two variables. Controlled Variable: A variable that is kept constant to remove potential effects on the dependent variable. Operationalising: Operationalising a variable is defining how a variable will be measured and changed in a research setting. 02 The research methodology refers to the techniques, processes or types of studies that researchers use to find information about psychological phenomena. A controlled experiment is when the causal relationship between two variables is investigated. Advantages of controlled experiments are that the cause effect between two variables can be examined meanwhile disadvantages include some experiments being ethically irresponsible and some variables not possible to test (such as grief). Between-Subjects Design: A between subjects design is when the sample is allocated to only the experimental group or the control group. Advantages of the between subjects design is that it reduces order effects, while disadvantages include requiring more participants than a within subjects design and participant differences. Within Subjects Design: The within subjects design has the sample complete both the control and experimental condition. Pros include the elimination of order effects and needing less participants, while disadvantages include potential order effects. Mixed Design: The mixed design is when the experimenter can compare between and within subjects, and includes two or more IVs. Pros include allowing experimenters to compare between and within participants while cons being more time and more resources. Case
