Conceptual metaphors influence memory automatically: Evidence from a divided attention false memory task.

Previous research has found that reading a list of ostensibly unrelated expressions based on the same underlying conceptual metaphor can evoke false recognition on a memory task for new expressions that use the same metaphor, the so-called conceptual metaphor false memory effect. We examined the automaticity of this effect by dividing participants' attention with a concurrent task. In Study 1, attention was manipulated while participants read the lists of expressions, whereas in Study 2, attention was manipulated both when they read the lists and when they were engaged in the later recognition memory test. Across both studies, the conceptual metaphor false memory effect was observed when conscious processing was limited by dividing attention. These data support the argument that conceptual metaphors are automatically activated when metaphorical expressions are read.
