How Associative Thinking Influences Scene Perception

Perception of our external environment is not isolated from the influence of our internal thoughts. Here, we investigate the nature of their interaction. We argue that a common associative mechanism underlies both the perception of scenes and our internal thoughts, and in three experiments hypothesize that there is a functional advantage to an associative thought pattern in the perception of scenes. Experiments 1 and 2 showed that associative thinking indeed facilitates scene perception, an effect that evolved over the course of the experiments. Experiment 3 showed that associative thinking hinders the perception of individual, isolated objects, in which associative information is minimized, but that object perception is facilitated when associative thinking is reduced. This double dissociation reveals that a match between the orientation of internal and external processing is key for perception, suggesting that an associative mind is more receptive of externally perceived associative information.
