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






2. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






3. Optic Nerve - sight






4. The visual image of the world on the retina






5. 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






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






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






8. 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






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






10. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






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






12. Olfactory Nerve - smell






13. Is everything anterior to the central sulcus






14. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






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






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






17. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






18. Vestibulocochlear Nerve - hearing and balance






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






20. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






21. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






22. 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)






23. There are 12 add more






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






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






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






27. Is found between the dura mater and arachnoid mater meninges






28. Increasing effects/effectiveness of a medication due to repeated administration






29. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






30. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






31. Most brain communications are with the opposite side of the body






32. Regulates body temperature






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






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






35. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






36. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






37. 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






38. Two different presynaptic neurons/inputs to a post-synaptic cell






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






40. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






41. Produce drowsiness and sleepiness






42. Midbrain - medulla and the pons






43. Holds the lens in place






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






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






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






48. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






49. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






50. Forebrain -band of nerve fibers connecting the two cerebral hemispheres
