| What is the capacity of short term memory? | 5-9 Pieces of information. |
| What is the duration of short term memory? | 18-30 Seconds. |
| How is short term memory encoded? | Acoustic (sounds) |
| What is the capacity for long term memory? | Unlimited. |
| What is the duration of long term memory? | Potentially a lifetime. |
| How is long term memory encoded? | Semantically (meanings). |
| What are the 3 types of sensory memory stores? | Haptic store (touch) Echoic store (hear) Ionic store (see). |
| What is memory? | A system of retaining information from daily experiences. |
| Factors effecting long term memory duration. | Intention to recall Amount of information to recall Depth of learning. |
| Factors effecting short term memory capacity. | Reading aloud Digit span Individual differences |
| Evidence for sensory memory. | Sperling Aim: To investigate how attentions effects sensory memory Method: Lab experiment and independent measures where participants given a grid to look at. There was two conditions. 1 - asked to look at first row of the grid. 2- asked to look at the whole of the grid. Results: The participants in condition 2 recalled more items on average because they paid attention to more items on the grid. Conclusion: The more we pay attention to the more is can recall, therefore attention does effect sensory memory. |
| Evidence for short term memory encoding. | Conrad Aim: To investigate how sound in an important feature in encoding in short term memory. Method: Lab experiment where students were presented with 6 consonants rapidly on the screen. There were 2 conditions. 1 - Acoustically different. 2 - Acoustically similar. the participants were then asked to write the letters in the correct order. Results: Conrad found those in condition 2 found it harder to recall the words and substituted same sounding words for similar sounding words. Findings: Short term memory in encoded acoustically. |
