Loftus and palmer - 2
Broken glass - a week later
Loftus and Palmer - results - 2
Smashed - yes - 16 - no - 34
Hit - yes - 7 - no - 43
Control - yes - 6 - no - 44
Loftus and Palmer - conclusion - 2
No broken glass was shown in the video ; therefore any reports are due to reconstructed memory as a result of a leading question
Loftus and Palmer - reliability
Internal - yes , replicable - clear number of controls
Loftus and Palmer - validity

Moray - experiment 1 - procedure
A short list of simple words was spoken 35 times as the rejected or blocked message. At the end of the shadowing task participants were asked to recall all they could remember from the rejected message - recognition test - 21 words - 7 from shadowed - 7 from rejected - 7 similar but not in
Moray - experiment 1 - results
7 words taken from the shadowed passage - 4.9
7 words taken from the list in the rejected message - 1.9
7 similar words that appeared in neither passage - 2.6
Moray - experiment 1 - conclusion
Almost none of the verbal content of the rejected message is able to penetrate the block set up
Moray - experiment 2 - aim
Found out that little to information pass through the inattentive barrier - wanted to find out what could break it - would a message with a strong enough meaning to the participant break the barrier
