Negative conditioned reflexes or inhibition of conditioned reflexes?

Answer 1

The established conditioned reflexes can be inhibited by some factors. The inhibition is of two types. External or indirect inhibition Internal or direct inhibition External or indirect inhibitionThe established conditioned reflex is inhibited by some form of stimulus, which is quite different from the conditioned stimulus. It is not related to conditioned stimulus. For example, some disturbing factors like sudden entrance of a stranger, sudden noise, or a strong smell can abolish the conditioned reflex and inhibit salivary secretion. The extra stimulus evokes the animal's curiosity and distracts the attention. According to Pavlov, this evokes an investigatory reflex. If the extra (inhibitory) stimulus is repeated for some time, its inhibitory effect gets weakened or abolished. Internal or direct inhibition There are four ways in which, the established conditioned reflex is abolished by direct or internal factors, which are related to the conditioned stimulus.
