Abstract
The aim of the experiment was to research whether leading
questions have influence on people.
The study done is a Loftus and Palmer (1974) replication. It was
laboratory experiment in which
16 students were tested. Independent variable was verb (smashed
and hit) set in two conditions.
Dependent variable was the estimated speed of the car crashing
when participants tried to recall
the stimulant (car crash video) from their memory. After
watching a video, the participants were
given a series of questions. According to the question asked,
participants gave different speed
estimates of cars when they crashed. Results indicated that the
verb used could have influenced
the memory and resulted in false reconstructed memory. Question
using verb smashed was
expected to give higher speed estimates than the question in
which the critical verb hit was used.
Where the verb smashed was used, speed estimates were 34.89
kilometers per hour (km/h) higher,
so we can say that the experiment was successful.
