Here are some results from an eye-tracking experiment I did once. These results look similar to self-paced reading results: each graph shows several jagged lines representing the reading times for each word in a sentence. Each graph has four different lines, because in my experiment I tested four different sentences. Don't worry about the labels; you don't need to understand all the details about the different sentences I used in this experiment.
When we looked at self-paced reading results before, we only needed to look at one graph, because there's only one way to measure reading time in a self-paced reading experiment. But this time there are six different graphs, because I calculated six different eye movement measures. Most of these measures (e.g. first fixation time, first pass time, go-past time, and total time) should be familiar to you by now.
Imagine that my research hypothesis was that the NOUN part of the sentence would be read more slowly in the "DE-some" and "UE-some" sentence types (represented by dashed lines) than it is in the "DE-onlysome" and "UE-onlysome" sentence types (represented by solid lines). You don't need to worry about what DE and UE mean; they are just labels from my experiment. All you need to know is that, for this example, we are imagining that I predicted the NOUN to be read more slowly in DE-some and UE-some sentences than it is read in DE-onlysome and UE-onlysome sentences.
Looking at these data, does it look like my prediction was correct or incorrect? Or is it impossible to make a conclusion? Why or why not?
