Unconscious processing refers to automatic thinking processing when individual consciousness
is not awakened. The traditional dual-processing model divides the processing system into logical system
and intuitive system, and believes that the intuitive system is easily affected by experience and emotion,
which leads to errors in decision-making. But Dijksterhuis found that when people encounter complex
situations, unconscious thinking can make better decisions than conscious thinking, and put forward
the theory of unconscious thinking. He believes that unconscious thought has many characteristics,
such as large capacity of information processing, free from the influence of power, and decentralized and
integrated processing from bottom to top, which makes it not limited to experience and stereotype in the
process of information processing, so it is superior to conscious processing in the decision-making of
complex and creative tasks. Although some of the experiments of unconscious thought showed the lack
of repetition and were questioned, they were generally supported by most of the evidence, and the doubts
about them could be effectively explained from the theoretical perspective. The theory of unconscious
thought provides a direction for future research on unconscious thought.
