Habituation is when the repetition of a stimulus leads to a decrease in its response. This serves to stop responding to stimuli that is potential important but situationally irrelevant. 


- Researchers theorize that it is related to a decrease in the efficiency of synaptic transmission, "a decrease that may be caused by a conductivity change in the membrane of the stimulated neuron’s iconic channels" (Camina and Güel, 2017).

Habituation

Sensitization is the increase in response to a stimulus after being repeatedly presented. 


- Sensitization may be related to a provision in transmission (presypnatic or postsypnatic). Although its effect is the opposite of habituation because there is an increase in response, the precesses underlying habituation may be the same as those in sensitization. 

Sensitization

Non-associative memory is learning that occurs when a behavior toward a stimuli changes without the presence of any associated stimulus or event; in contrast to associative memory, no direct connection is made between stimuli and a respective response. There are two important processes of non-associative memory:

- Habituation
- Sensitization

References for implicit memory

Priming is an effect where an individual's exposure to certain stimuli influences their response to a stimuli presented later without being consciously aware of it.

Priming

Associative memory is the unconscious retrieval and storage of information through association with other information. Associative memory can be acquired through two different learning processes: 

- Classical conditioning
- Operant conditioning

Associative memory

Non-associative memory

Implicit memory involved in recalling motor and executive skills necessary to perform tasks. Procedural memories develop through continuously repeating a complex task until all the neural systems involved working together are automatized.
