A female rodent exposed to high levels of testosterone while in the mothers uterus is likely to
show more interfemale aggression as an adult

Which of the following results from studies of people with spinal cord injuries supports james-lange theory of emotion?
people who could not feel reactions from most of their bodies reported that they no longer felt intense emotions.
Studies by Ekman and colleauges suggest that
simulated facial emotional expression changes sympathetic activity
The various stages of sleep are easily distinguished by
changes in the electrical activity of the brain
The ___ is an instrument used to record electrical potentials from muscles during sleep
The ___ pattern of the EEG activity is characterized by irregular, high-frequency, low voltage waves
The observation that a persons brain shows beta wave activity is not a reliable indicator of being awake because
this brian wave pattern also appears during sleep
The translation between wakefulness and sleep is marked by the appearance of ___ waves in the sleep record
The theta brain wave pattern is characterized by changes in frequency of electrical activity of
You are watching a sleep record of a person whose record contains 85% delta wave activity. Your best guess is that this person is
in stage 4 of slow wave sleep
A key aspect of slow-wave sleep is the presence of ____ Hz oscillations comprised of a down state followed by an up state
___ will occur soon after the appearance of rapid eye movements in the sleep record.
Sleep stages 1-4 are termed ___, whereas stages 3-4 are referred to as___.
non-REM sleep; slow wave sleep
