# Digit Span Evaluation: Summary

You have now completed the module on evaluating digit span evidence. The most important ideas when evaluating digit span evidence are:

- In laboratory experiments like Miller's and Simon's, participants are put in an unfamiliar situation
- They may feel anxious about the laboratory environment and feel under pressure to perform well
- This may affect the way they carry out the experimental tasks, and the results that are produced
- Consequently, digit span research has low ecological validity and may be of limited relevance to real-world behaviour
