Most and colleagues (2001) asked participants to track either white or black shapes as they moved across a screen. They then asked these participants if they had noticed an unexpected object which had also moved across the screen during the task. Which statement best reflects their findings:

Question

Answer

Participants were highly unlikely to notice the unexpected object. Rates of noticing were not affected by the luminance of the unexpected object, and were also not affected by whether or not participants were talking on a mobile phone during the task.

Answer

Participants were highly unlikely to notice the unexpected object. Rates of noticing were not affected by the luminance of the unexpected object, though they were affected by whether or not participants were talking on a mobile phone during the task.

Answer

There was a linear trend in the likelihood of participants noticing the unexpected object   they were more likely to notice the unexpected object if it was less similar in luminance to the objects that they were tracking.

Answer

There was a linear trend in the likelihood of participants noticing the unexpected object   they were more likely to notice the unexpected object if it was more similar in luminance to the objects that they were tracking.
