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. A single - unfertilized cell created during conception; the combined egg + sperm






3. Is characteristic of indirect antagonist drugs






4. 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






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






6. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






7. Maintains balance/posture and coordinates body movements






8. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






9. Expression of traits






10. Is regulated by the hypothalamus






11. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






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






13. Trigerminal Nerve - face sensation






14. 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






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






16. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






17. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






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






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






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






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






22. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






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

24. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

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






26. 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)






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






28. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






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






30. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






31. Caudate nucleus and putamen






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






33. Is characteristic of indirect antagonists






34. 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)






35. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






36. 'little brain'






37. 'covering'






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






39. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






40. The maintenance of water balance in the body






41. Important to motor system






42. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






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






44. Pleasure center of the brain; discovered by Olds & Milner






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






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






47. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






49. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






50. 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
