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. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






2. Important to motor system






3. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






4. Audition: protrusions on top of midbrain; part of auditory system






5. Expression of traits






6. The visual image of the world on the retina






7. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






8. Consummatory stimulus






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






10. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






11. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






12. Regulates body temperature






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






14. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






15. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






16. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






17. 'Roof'






18. Controls sexual activity






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






20. The viscous substance between cornea and lens






21. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






22. In the CNS - is an amino acid that stabilizes neural activity






23. Caudate nucleus and putamen






24. Absolute; relative






25. Trochlear Nerve - moves eye






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






27. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






28. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






29. Opening in the iris; dilates and contracts allowing different levels of light in






30. Is regulated by the hypothalamus






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






32. Is characteristic of indirect antagonists






33. 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)






34. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






35. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






36. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






37. A peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






38. Accessory Nerve - moves the head






39. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






40. Projects to ventral tegmental area






41. 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






42. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death

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






44. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential






45. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

46. Measure changes in the electrical resistance of the skin (sweat gland activity)






47. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






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






49. Supernormal






50. Holds the lens in place
