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






2. Supernormal






3. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






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






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






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






7. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






8. The increase in REM sleep seen after a period of REM sleep deprivation






9. 'Roof'






10. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






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






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






13. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






14. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






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






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






17. 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






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






19. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






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






21. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






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






23. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






24. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






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






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






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






29. ...






30. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






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






32. Made from within - natural






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






34. Caudate nucleus and putamen






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






36. Is characteristic of indirect antagonist drugs






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. 'little brain'






39. Expression of traits






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






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






42. Contains delta activity - stages III and IV






43. Is characteristic of indirect antagonists






44. Optic Nerve - sight






45. Are found in the diencephalon






46. Self-dissolving






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






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






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






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