Interoceptive conditioning: An attempt at replication

Excitatory conditioning to the interoceptive nicotine stimulus blocks subsequent conditioning to an exteroceptive light stimulus.

Previous research has shown that a nicotine conditional stimulus (CS) can compete with (i.e., overshadow) a brief light CS. Another form of competition, blocking, has not yet been examined with the nicotine CS. Groups of rats were assigned to an element training condition. For the N+ group, during each daily 2h element training session, there were ten intravenous nicotine infusions (0.03 mg/kg)...

An Attempt at Frankl’s Conjecture

In 1979 Frankl conjectured that in a finite union-closed family F of finite sets, F = {∅} there has to be an element that belongs to at least half of the sets in F . We prove this when | F| 10.

Modeling the development of panic disorder with interoceptive conditioning.

Panic disorder is characterized by the paroxysmal occurrence and fear of bodily symptoms. In recent years it has been proposed that patients "learn" to fear cardiorespiratory sensations through interoceptive conditioning. This study sought to model the initial stage of this process in healthy volunteers (N=44) using mild cardiac sensations. An additional aim was to explore whether anxiety sensi...
