Evaluation - Blakemore and Cooper

• Evaluation - Research Method (Lab experiment)


  +Highly controlled environment reduces extraneous variables such as vertical or horizontal striped

  -Low ecological validity - not true to life and may not apply to all situations
• Evaluation - Data (Quantitative)

  -Lacks detail and reasons why the cats responded as they did

  +Data can be easily compared
• Evaluation - Data (Qualitative)

  +Lots of detail rich data so we know why they behaved as they did

  -Hard to compare
• Evaluation - Validity 


  +High internal as there were tight controls such as being kept in complete darkness

  +Face and concurrent as measures what it intends to and biased off of other studies

  -Low ecological validity as it was an artificial lab experiment
• Evaluation - Reliability 


  Internal - only two cats in each condition

  External - standardised procedures allows it to be repeated
• Evaluation - Sample (2 lab raised cats )


  -Only two cats so lacks generalisability 

  -Cannot elaborate results from cats to human
• Evaluation - Ethics 


  Conducted within ethical guidelines set by the home office at the time

  Research on animals should aim to replace, reduce and refine their work on animals. They did reduce and refine but cause permanent damage
