Methodology: Mouse-tracking
• Mouse trajectories can tap into multi-stage decision processes
• Compared to SAT techniques• Advantages: no extra cognitive load, natural for participants, fewer trials required
• Now used in many domains• Software: MouseTracker (Jon Freeman)

Discussion• Predictability of important words in a sentence seems to be
a critical factor for how easily negating elements can be incorporated incrementally
• This is an effect beyond the correlation between predictability and pragmatic felicity (all sentences are felicitous in the context)
• Why is this? Two possible interpretations:● Predictability facilitates processing in a similar way to
pragmatic felicity● The apparent ease of processing is an illusion
produced by people employing an anti-prediction strategy where available
