LATENT INHIBITION Meaning and
Definition
-
Latent inhibition is a psychological concept that refers to the ability of an organism to ignore or become less responsive to irrelevant stimuli that have previously been encountered but have not been paired with any significant consequence or event. It is essentially the process by which the brain filters out and suppresses the attention given to unimportant or familiar stimuli.
In practice, latent inhibition can be observed in various situations, such as when we encounter a sound or sight that we have been exposed to multiple times without any noteworthy outcome. The brain recognizes these stimuli as non-threatening or unimportant, leading to a reduced level of attention or arousal. This cognitive mechanism allows individuals to efficiently direct their attention and mental resources to new or relevant stimuli in their environment.
However, when there is a disruption in the latent inhibition process, individuals may experience difficulties in ignoring or filtering out irrelevant information, leading to issues such as distractibility or sensory overload. In some cases, impaired latent inhibition has been associated with certain mental health conditions, such as schizophrenia or attention deficit hyperactivity disorder (ADHD).
Overall, latent inhibition is a cognitive process that serves to protect individuals from being overwhelmed by irrelevant stimuli in their surroundings. It plays a crucial role in attention regulation and the efficient allocation of mental resources.
Etymology of LATENT INHIBITION
The word "latent" originates from the Latin word "latēns", which means "lying hidden" or "concealed". "Inhibition", on the other hand, comes from the Latin word "inhibitio", which means "restraint" or "holding back".
Therefore, the term "latent inhibition" combines these two words to refer to a psychological concept related to the ability of an organism to disregard or "inhibit" previously learned information or stimuli that are no longer relevant or necessary. The term was likely formed to describe the underlying mechanism or process responsible for suppressing or inhibiting the processing and response to irrelevant stimuli.
