Dimensional Relevance Modulates Early Response priming

Based on our experiment design, we expect that the prime will elicit early, automatic response activation in a feedforward manner. Specifically, we predicted that the priming effect increases with prime target SOA and with prime visibility. Extending this, we propose that dimensional relevance gates response activation. We hypothesise that the priming effect will be stronger when the prime feature (shape or colour) is congruent with the task-relevant dimension. In the colour-relevant task, the priming effect is independent of the shape. Conversely, in shape-relevant tasks, the priming effect is independent of colour.
