Which of the following is NOT an argument against the precategorical nature of iconic memory?

A. When Turvey (1973) presented a letter and a brightness mask to different eyes it had no effect, but if they were presented to the same eye there was an effect. When he used a pattern mask, he got effects in both cases.
B. Merkle (1980) cued subjects to recall either the digits or the letters in a partial report procedure and found an advantage similar in size to cuing with physical location.
C. Errors in the partial report task tend to be auditory confusions not visual.

Ans: A. When Turvey (1973) presented a letter and a brightness mask to different eyes it had no effect, but if they were presented to the same eye there was an effect. When he used a pattern mask, he got effects in both cases.
