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. Holds the lens in place






2. Is everything anterior to the central sulcus






3. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






4. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






5. Transparent substance between lens and retina






6. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

7. Absolute; relative






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






9. Moving forward






10. Binding of drug to receptor site that doesn'T interfere with the principal ligand






11. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






12. Has neurons for reflexes






13. Consummatory stimulus






14. If head is rotated - eye movements occur in the same direction






15. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






16. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






17. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






18. Self-dissolving






19. 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)






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






21. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






22. Made from within - natural






23. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






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






25. Sleep tests (i.e. to diagnosis sleep apnea)






26. Accessory Nerve - moves the head






27. Is found in the interior rostral temporal lobe - part of limbic system






28. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






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






30. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






31. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






32. Cumulative effects of repeated stimulation from a presynaptic neuron






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. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






35. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






36. Hypothalamic-pituitary-adrenal axis -controls stress response






37. 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)






38. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






39. 'covering'






40. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






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






42. Are found in the diencephalon






43. Hormones that reduce pain






44. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






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






46. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






47. Combines input from diverse brain regions; receives sensory information/sends motor impulses






48. Some brain communications are with the same side of the body






49. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






50. Maintains balance/posture and coordinates body movements
