Background + Aim of S&C (1999)

What’s the background study of Simons & Chabris (1999)?

Neisser (1979)

What did Neisser (1979) do in relation to S&C (1999)?

Neisser created a task where participants had to monitor basketball passes between either a white shirt team or a black shirt team.

How did Neisser film the 2 teams in their task?

They filmed the 2 teams seperately, as well as the unexpected event, and superimposed them over each other. Both scenes were left slightly transparent because technology wasn’t good enough to superimpose without doing so.

What did Neisser find when they conducted this task?

They found that 48% noticed the unexpected event of a woman with an umbrella. Additionally, when participants didn’t have to monitor passes, they all noticed the UE (Unexpected Event)

What was the problem with Neisser producing the video?

The problem with superimposing 2 videos on top of each other is that it will create an odd appearance, one that isn’t typically seen / experienced in the real world.

What was the aim of the study?

Aim was to investigate whether inattentional blindness of unexpected objects occurs in dynamic scenes, under controlled conditions
