An Example of the Difference Between Perception and Conscious Perception

question 1

Multiple Choice

An example of the difference between perception and conscious perception is shown by Moore and Egeth (1997) , who showed participants a display containing two horizontal lines and a series of surrounding dots. In one trial the lines and dots were arranged to produce the Müller-Lyer illusion (an illusion that causes two same-length lines to look different in length) . In this experiment, MOST participants were

• A) consciously aware of the Müller-Lyer pattern and perceived the two lines to be of the same length.
• B) consciously aware of the Müller-Lyer pattern and perceived the two lines to be of different lengths.
• C) not consciously aware of the Müller-Lyer pattern and perceived the two lines to be of different lengths.
• D) not consciously aware of the Müller-Lyer pattern and perceived the two lines to be of the same length.
