Evidence from dual-process and cognitive behavioral theorists points to the conclusion that the products of associative learning are sometimes available in working memory. Adolescents, adults, and children (to a lesser extent) can engage in "metacognitive intercession," reflecting on the products of associative processing and deciding whether to assimilate these products to existing knowledge or create new levels of understanding. To highlight my arguments, I discuss research on belief-biased reasoning and an intervention that reduced reasoning biases.
