Abstract: This paper reviewed the cognitive bias of Panic Disorder on attention, interpretation and memory. We concluded that the attention bias can enhance anxiety feelings, the interpretative bias can increase anxiety levels and the memory bias can facilitate the retrieve of anxiety experiences. As studies have shown that these three kinds of cognitive bias maybe are the vulnerable factors of PD, and also maybe are the key factors in developing and maintaining of PD

Key words: Panic Disorder, attention bias, interpretative bias, memory bias
