The Avoidance Model of Worry (AMW) theorizes that worry is a verbal linguistic, thought based activity, which arises as an attempt to inhibit vivid mental imagery and associated somatic and emotional activation [REF].
This model explains pathological worry to be an interaction between involuntary (bottom-up) processes, such as habitual biases in attention and interpretation favoring threat content, and voluntary (top-down) processes, such as attentional control.
