When the producer participates in the experiment, she is instructed to think about certain kinds of stimuli, such as a hammer or an apartment. When the computer analyzes her thoughts, it is making a decision about whether she thought about a tool or a dwelling. Considering these methods, which of the following is a valid criticism of this experiment? 1. Because the computer is indicating what the participant should think about, it knows what the correct answer should be for each trial. 2. The computer isn't really reading people's thoughts, it's making a probability-based choice between two very different kinds of thoughts. 3. This research is pointless, because it doesn't have any real-world application. 4. The person's thoughts can be identified only after the computer has had a chance to record their brain activity for a wide range of objects.
