what critical question where group one asked
“about how fast the cars where going when they hit into each other?”

found that all conditions most pp correctly identified that their was no broken glass in film clip
a significantly higher number of of pp in the ‘smashed’ group (16) repported seeing glass that the ‘hit’ group (7)
what did Loftus and Palmer conclude
they argue that 2 kinds of information go into a persons memory for a complex event
what where the two types of memory
info at the time of the event
info supplied to us after the event
what do these two types of info create
this creates an overall memory of the event called reconstructive memory
what is this memory called
reconstructive memory
in total what did Loftus and Palmer conclude
that leading questions do influence EWT
