Freud believed dreams represent

Answer: Unconscious wishes and desires (manifest vs latent content) Manifest = surface story; latent = hidden meaning.

Circadian rhythms are

Answer: Approximately 24-hour biological cycles Body temperature, hormones, and alertness follow this daily pattern.

The stage described in the study is best identified as

Answer: REM sleep Fast desynchronized EEG, rapid eye movements, atonia, and vivid narrative dreaming are hallmark features of REM (rapid eye movement) sleep.

Sample 3difficulty 3/5
$In a study, researchers monitored EEG, EMG, and EOG recordings from sleeping participants across the night. They observed periods of fast, low-amplitude brain waves accompanied by rapid eye movements and near-paralysis of skeletal muscles. When awakened during these periods, 87 percent of participants reported vivid story-like dreams, compared with 25 percent in other stages.$
$The stage described in the study is best identified as$
- A
  $REM sleep$
  check_circle
- B
  $Stage N1 (light NREM)$
- C
  $Stage N3 (slow-wave sleep)$
- D
  $Stage N2 (with sleep spindles)$
Why
$Fast desynchronized EEG, rapid eye movements, atonia, and vivid narrative dreaming are hallmark features of REM (rapid eye movement) sleep.$

Sample 4difficulty 3/5
$In a study, researchers monitored EEG, EMG, and EOG recordings from sleeping participants across the night. They observed periods of fast, low-amplitude brain waves accompanied by rapid eye movements and near-paralysis of skeletal muscles. When awakened during these periods, 87 percent of participants reported vivid story-like dreams, compared with 25 percent in other stages.$
$According to the activation-synthesis hypothesis, the vivid dreams reported in this stage are best explained as$
- A
  $The cortex's attempt to make sense of random neural activity originating in the brainstem$
  check_circle
- B
  $Symbolic expressions of repressed unconscious wishes$
- C
  $Hallucinations caused by sensory deprivation$
- D
  $Memories being literally replayed in real time$
Why
$Activation-synthesis (Hobson & McCarley) proposes that REM dreams arise as the cortex synthesizes a coherent narrative from random brainstem signals.$

Sample 5difficulty 3/5
$Insomnia is$
- A
  $Repeated breathing pauses that disrupt sleep continuity$
- B
  $Persistent difficulty falling or staying asleep$
  check_circle
- C
  $Sudden uncontrollable sleep attacks during the daytime$
- D
  $Episodes of complex motor behavior during slow-wave sleep$
Why
$Can be triggered by stress, anxiety, or poor sleep habits.$
