Chalmers (2004), Wu (2010), and Block (2010) have independently argued that the effect of attention on the content of perception raises a challenge for representationalism.
Covert shifts of attention seem to involve a change in the phenomenal character of perception, without a corresponding change in representational content. Adrienne Prettyman (Toronto) shows that the challenge fails because the arguments provided do not rule out a change in representational content. She argues that the strongest version of the challenge dissolves once we accept that there can be different ways of veridically representing the same object in perception.
