In a subliminal perception experiment, a number of irregular shapes are “flashed” for 1 millisecond in front of DeShawn. He is then shown two shapes—the one that was flashed and a new one—and asked to say which of the two he had previously seen, and which he preferred. While unable to correctly recognize the old shapes better than chance, DeShawn still showed a preference for them at better than chance levels. What does this finding suggest?
The shapes were too similar to be distinguishable.
We must have a preference for familiar things.
We cannot sustain our attention during such a task.
We are unable to perceive shapes flashed quickly
