| Paper 1 | Memory |
| What is sensory memory | -where information from our senses is stored temporarily -unless we pay attention to it decays -it has a limited capacity -info is coded depending on the sense |
| What is STM? | -Short term memory is coded acoustically -7+/- Items capacity -15-30 second duration -Study was done by Peterson and Peterson |
| What is LTM? | -Coded semantically -unlimited capacity -Duration indefinite -Study by Bahrick et al -3 types: episodic, semantic and procedural |
| Episodic memory | -stores info about events that you've experienced, ie concerts or visits out contains info about time and place, the emotions you felt and the details of what happened, they can consciously be recalled |

| Method? | -lab exp -P's given a grid with 3 rows of four letters -for 0.5 seconds then had to immediately recall either the whole or rows based on a tone |
| Results? | -when told to recall all grid they only managed four or five letters -when a row was indicated the p's recalled an average of 3 items recalled, no matter which row was indicated. |
| Conclusion? | -Almost the whole grid was held in their sensory memory, they couldn't record it all however as it began to fade before they finished of recall. |
