Evaluation of Peterson and Peterson study

The researchers used fixed timings for participants to count backwards from. They also eliminated noise and other factors that could have had an influence on memory.

• Strength

• Weakness

The previous question was a strength because......

• High control enhances reliability

• Low control enhances reliability

Reliability is a strength because

• it means the study cannot be replicated and the reliability of the findings can be checked to make sure they were not a one-off result.

• it means the study can be replicated

• it means the study can be replicated and the reliability of the findings can be checked to make sure they were not a one-off result.

The study has practical implications as it shows us

how interference in the form of verbal distractions can affect our ability to retain information.

So what should we avoid when revising?

• Distractions

• Fast food

• Going outside

What does mundane realism mean?

• Un - realistic,everyday task.

• a realistic, everyday task.

• variables that could affect the results of a study.

• when the outcomes of a study are consistent.

How does Peterson and Peterson lack mundane realism

• Remembering 3 letters such as a trigram and counting backwards is not an everyday activity

• Remembering 3 letters such as a trigram and counting backwards is an everyday activity

The study is scientific because ......

• It has good control, using standardised procedures to make sure all participants experienced the same process.

• It it demonstrates how interference in the form of verbal distractions can affect our ability to retain information.

• the use nonsense trigrams for participants to remember because real words could have personal relevance for some participants
