Answer:

K-complexes

Explanation:

Like sleep spindles, K-complexes are defining brainwaves of stage 2 sleep. They differ from sleep spindles in their form. Unlike the rapid burst of activity represented by sleep spindles, K complexes are large waves that react to external stimuli while sleeping.

K-complexes also develop later than sleep spindles. Sleep spindles develop at about 6 weeks of age, while K-complexes do not show up until about 5 months.

K-complexes form as a reaction to external stimuli in the bedroom or outside while a person is asleep. Sleep spindles follow K-complexes as the brain works to stay asleep.

Abnormal K-complex activity is linked with epilepsy, restless legs syndrome (RLS), and obstructive sleep apnea. For example, RLS sufferers experience a higher volume of K-complexes, which typically happen right before the leg movements. This increased K-complex activity may contribute to the less restful sleep associated with restless legs syndrome.

Lana71 [14]

Answer:

This is an example of the encoding specificity principle.

Explanation:

According to the encoding specificity principle, memories are connected to the context in which they were created. As a matter of fact, retrieving a memory will be more easily done if the context and the cues of the current moment somehow duplicate the conditions present when the memory was formed. That is why Sharon cannot remember who the veterinarian is. They are not in his office, he is not wearing the usual attire, and so on. The context and the cues do not resemble the usual ones.
