Answer 2

limited capacity
limited duration

Question 3

long term memory

Answer 3

permanent
usually semantic

Question 4

sensory register - duration - method

Answer 4

sperling
in a laboratory experiment, participants were shown a grid with three rows of four letters for 50 milliseconds then had to immediately recall either the whole grid or a randomly chosen row indicated by a tone (high, medium, low) played straight after the grid was shown

Question 5

sensory register - duration - results

Answer 5

when participants had to recall the whole grid, they only managed to recall four or five letters on average
when a particular row was indicated, participants could recall an average of three items no matter which row was selected

Question 6

sensory register - duration - conclusion

Answer 6

the participants didnt know which row was going to be selected, so it could be concluded that they would have been able to recall three items from any row, therefore almost the whole grid was being held in their sensory register
they couldnt report the whole grid because the trace faded before they could finish recall
