Answer:
True.
Explanation:
Stage 1 of NREM sleep is characterized by a low amplitude EEG, mixed frequency between range a and s (2 to 7Hz). EMG activity is usually higher than at other stages of sleep, but amplitude can vary widely. Stage 2 of NREM sleep is recognized by background activity and episodes of sleep spindles and K-complexes. Sleep spindles are short (12 to 14 Hz) waves that increase and decrease in amplitude to produce a spindle characteristic. Stage 3 NREM sleep is classified when slow waves or d waves (£ 2Hz) and high amplitude greater than 75mV (measured from lowest to highest wave - peak to peak) appear at 20 to 50% of the time of the day. record. Stage 4 NREM sleep is similar for EEG, EMG, and EOG from the previous stage; however, stage 4 is characterized by the presence of d waves in more than 50% of the time.
Accordingly, we can conclude that going through the NREM stages (1 to 4), the frequency of EEG waves decreases but their amplitude increases.
Answer:
is having difficulty with mental representations.
Explanation:
During the sensorimotor phase of the child's development (from birth to 2 years old), the child learns about the world through his senses and the manipulation of objects. The main achievement during this phase is the permanence of the object, that is, knowing that an object still exists, even if you cannot see it. This requires the ability to form a mental representation of objects. Through mental representation, it is also possible for the child to understand that a model and the larger object with which it resembles represent the same thing.
If the child cannot understand these things, this child may be having difficulty with mental representations.
