In response priming, the reaction times to classify an object can be affected by previous exposure to a similar object. Most priming experiments focus on how primes prime a target. In the following set of experiments, we investigate how the interaction between two primes prime a target. Specifically, we address if the offsets of the two prime verniers integrate before they prime, and which prime, if any, dominates the integration (and therefore, the priming). We show that the offsets of the primes fuse before they prime. However, other features of the primes (such as color or temporal location) changes how the primes integrate with each other and hence, priming. We see that when the two primes do not equally integrate, the second prime dominates over the first prime.
