Most people are able to ignore the constant stream of incoming stimuli, but this capability is reduced in those with low latent inhibition.
Low latent inhibition (that may resemble hyper-activity in early decades of the individual life) seems to often correlate with distracted behaviors.
This distractedness can manifest itself as general inattentiveness, a tendency to switch subjects without warning in conversation, and other absentminded habits. […]
This is not to say that all distractedness can be explained by low latent inhibition, nor does it necessarily follow that people with low LI will have a hard time paying attention.
It does mean, however, that the higher quantity of incoming information requires a mind capable of handling it.
These individuals tend to sense other’s pain and suffering as they are very sensitive persons.
Those with less than average intelligence, on the other hand, are less able to cope, and as a result are more likely to suffer from mental illness and sensory overload.
It is hypothesized that a low level of latent inhibition can cause either psychosis or a high level of creative achievement or both, which is usually dependent on the individual’s intelligence.
When they can not develop the creative ideas, they become frustrated and/or depressive.
Furthermore, it does not necessarily lead to mental disorder or creative achievement—this is, like many other factors of life, a case of environmental and predispositional influences, whether these be positive (e.g., education) or negative (e.g., abuse) in nature.
