Gre Psychology: Experimental/natural Science Biology

Subjects : gre, psychology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






2. Functions as both a hormone and a neurotransmitter in the brain






3. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






4. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






5. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






6. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






7. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






8. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






9. Is a peptide neurotransmitter and a natural painkiller and antianxiety






10. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






11. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells






12. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






13. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

14. Sleepwalking - sleep talking






15. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






16. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






17. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






18. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






19. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






20. All have similar molecular structure - so many 'dirty' medications






21. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






22. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






23. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






24. Synchronized EEG activity during its deeper stages






25. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






26. A single - unfertilized cell created during conception; the combined egg + sperm






27. Is an oversensitivity to dopamine (D2)






28. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






29. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






30. Trochlear Nerve - moves eye






31. Pleasure center of the brain; discovered by Olds & Milner






32. Is everything anterior to the central sulcus






33. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






34. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






35. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






36. Viscous substance between cornea and lens; transparent substance between lens and retina






37. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






38. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






39. Emotional perception and expression (particularly fearful emotions and detection of threat)






40. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






41. Found in the ventricles and spinal canal






42. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






43. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






44. Controls sexual activity






45. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






46. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






47. Self-dissolving






48. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






49. Is used as an anaesthetic for children and animals but causes psychosis in adults






50. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)
