Bower and Springston (1970)
Aim: To test the effects of chunking
Method: They had two groups of participants. The control group was presented with groups of letters such as: FB, IPH, DTW, AIB, and M. The experimental group was given the same letters but grouped differently: FBI, PHD, CIA, IBM.
Results: The experiemental group recalled more letters than the control group
Conclusion: The researchers concluded that 'chunking' increases the capacity of our short-term memory. These groups of three letters refer to things we already know e.g. FBI - Federal Bureu of Investigation. This information is stored elsewhere in our long-term memory.
