• WHY DO THE RESULTS LACK ECOLOGICAL VALIDITY?

  artificial setting
• WHY DO THE RESUTS LACK INTERNAL VALIDITY?

  artificial setting (participants more likely to guess the aim and respond to demand characteristics)
• WHAT DOES THE LACK OF INTERNAL VALIDITY OF CONTROLLED OBSERVATIONS SUGGEST?

  researcher is not measuring what they intend to measure
