This study investigated explicit (cued recall) and implicit memory (word completion) memory bias for catastrophic associations among individuals with panic disorder (n = 24), clinician controls (n = 24), and normal controls (n = 24). Compared to both control groups, the panic disorder group showed biased explicit and implicit memory for catastrophic associations to bodily sensation words (e.g., palpitation-coronary) compared to positive (e.g., smiles-elation) and neutral (e.g., groceries-coupons) word pairs of equal relatedness. These results support cognitive formulations of panic disorder which suggest that individuals with panic disorder have biased memory for
