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. Moving forward






2. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






3. Skin senses that register the sensations of pressure - warmth and cold






4. Controls sexual activity






5. Cumulative effects of repeated stimulation from a presynaptic neuron






6. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






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






8. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






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






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






11. Hormones that reduce pain






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






13. 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)






14. Includes the tectum and tegmentum






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






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






17. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






18. Include tolerance (possible withdrawal) and sensitivity






19. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






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






21. Precursor to the catecholamine neurotransmitters (DA + NE)






22. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






23. 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)






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






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






26. Synchronized EEG activity during its deeper stages






27. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






28. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






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






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






31. Trochlear Nerve - moves eye






32. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






33. Is regulated by the hypothalamus






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






35. Damage to this are causes clumsiness and loss of balance






36. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






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






38. 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






39. 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






40. Vagus Nerve - heart rate and digestion






41. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






42. 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






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






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






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






46. Glossopharyngeal Nerve - taste swallow






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






48. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






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






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