AIM: To see if rehersal is necessary to hold information in the STM
METHOD: Participants were shown 3 letter words (i.e WKG, THY) and were asked to remeber them. Immediately, they were then asked to count backwards in 3s from 100 for different lengths of time. They were then asked to recall the trigrams in the correct order.
RESULTS: It was found that virtually all the information was forgotten after 18 seconds.
CONCLUSION: Rehearsal is necessary to hold informmation in the STM (duration is around 18 seconds)
EVALUATION:
-Nonsense syllables are not the type of memory tasks in real life therefore it lacks mundane realism
-It was a lab study therefore it lacks ecological calidity as there was hihc control over the variables
+It helps us understands why postcded and our car number plate never exceeds 7 chuncs of information (capacity of STM)
