Increased anxiety during anticipation of unpredictable but not predictable aversive stimuli as a psychophysiologic marker of panic disorder.
OBJECTIVE Predictability is a fundamental modulator of anxiety in that the ability to predict aversive events mitigates anxious responses. In panic disorder, persistent symptoms of anxiety are caused by anticipation of the next uncued (unpredictable) panic attack. The authors tested the hypothesis that elevated anxious reactivity, specifically toward unpredictable aversive events, is a psychoph...

متن کاملPredictable semiautomata
We introduce a new class of nondeterministic semiautomata: A nondeterministic semiautomaton S is predictable if there exists k ≥ 0 such that, if S knows the current input a and the next k inputs, the transition under a can be made deterministically. Nondeterminism may occur only when the length of the unread input is ≤ k. We develop a theory of predictable semiautomata. We show that, if a semia...
متن کاملRat's Anticipation of Diurnal
Rats, confined either to Skinner boxes or to activity wheels, were fed at regularly scheduled feeding times which were either diurnal, i.e., every 24 hr., or a-diurnal, i.e., every 19 or 29 hr. Even though the a-diurnal Ss had been born, reared, and tested under 19or 29-hr, schedules to provide further support for the anticipation of feeding, they failed to show such an effect. The fact that th...
