    can someone explain eyewitness testimony with lab and or field experiments to me

    Loftus and Palmer did lab studies in their studies where they asked people to watch a car crash video. They then asked participants "how fast do you think the car was going when they _*__?" *hit, smashed, collided, bumped, contacted.

    As this was a lab study it was artificial. A video isn't as emotionally arousing as real-life and demand characteristics may have been present, it's possible to control extraneous variables which means we can establish cause and effect.

    For field experiment you could look at research which involves staged crimes.

    Is this what you mean?

Do you agree with the proposed ban on plastic straws and cotton buds?
