• Experimental Psychology


  Objective observation of phenomena which are made to occur in a strictly controlled situation in which one or more factors are varied and the others are kept constant
• Objective Observation

  • Ability of researcher to measure and record behaviour in a systematic and precise manner using a reliable standard to avoid subjective measurement
  • Accepting the possibility that mistakes can occur
  • Attempt to identify where the mistakes are likely to occur
  • Take the necessary steps to avoid the errors
• Phenomena that are made to occur

  Experimenter is manipulating the conditions that cause a certain effect to identify cause-and-effect relationships
• Strictly controlled situation

  Need to eliminate the influence of variables other than those manipulated by the experimenter
• One or more factors are varied and the others are kept constant

  Constancy refers to controlling or eliminating the influence of all variables except the one (or ones) of interest<|>Variation refers to the independent variable being manipulated along a defined range
• Experimental Research Settings

  • Field Experimentation
  • Laboratory Experimentation
• Commonly used experimental designs

  • Within Subject Design
  • Between Subject Design
  • Factorial Design
